When I speak with parents and colleagues about the well-being of today’s youth, the nearly unanimous cry is the negative effects of social media. But then, after a few moments of silence they say, “I don’t know how we can stop it. The genie is out of the bottle.”

The helplessness we as responsible adults and professionals feel about our inability to change this cultural shift to youth fixation on social media and its increasingly clear impact on depression, anxiety, self-esteem, and even suicide is profound. In China the country has “simply” regulated access to the Internet for children to 2 hours per day and blocked many websites. But such universal restriction is not likely in the United States. We need some other solutions.
 

A solution for all ages

Reach Out and Read, an international program promoting early relational health and literacy by encouraging and modeling reading and handing out books to families with children aged 0-5 years, has significant evidence for improving child development and parent-child interaction.

But why stop promoting reading and the associated parent-child bonding at 5 years old? Academic progress, child mental health and well-being, and family relationships are all currently in trouble and could all benefit from more reading. As pediatric providers for all ages of children and youth we can effectively promote reading as part of preventive care, not just for the youngest.

Reading fluency is a key factor in academic success. A study from 2019, before the pandemic, found that by the end of high school, students were reading 19% slower than were students of a similar age 50 years ago. The possible reasons, among many, include poverty with its effect on vocabulary, modeling and access to books, hours on social media, and less unstructured time to read for pleasure. With less reading comes less practice. Reading then doesn’t feel as comfortable and is avoided.

The pandemic made measures of academic level even worse, with reading fluency in second and third grade now about 30% behind what would be expected. Reading fluency and comprehension become more critical for future academic progress beginning in third grade when “learning to read” shifts to “reading to learn.” Educators are doing their best to catch children up but with limited support resources, and families need strategies to help their children.

Early strategies to promote reading by discussing the benefits with parents of bedtime stories and sharing books seems easy in comparison to encouraging school-aged children and older youth to read. But there are good reasons and strategies to persist.

Reading can help a child’s mental health as well as development. After a day at school, picking up another book may seem to the parent like more homework. But “reading for pleasure” is different. Reading has been shown to lower heart rate and muscle tension and reduce stress by as much as 68% in minutes, even lowering cortisol and activating pleasure centers of the brain. An immersive story can distract one from worries and be a real escape; the opposite of looking at social media online where peer comparisons and a constant stream of nasty comments 24/7 are culprits producing anxiety, depression, eating disorders, and suicide. Books that have characters going through similar struggles as those of the youth provide a sense of not being alone with these stresses and generally include models of problem solving and resolution that can inspire hopefulness. Joining (or starting) a kids’ or parent-child book club offers a chance to socialize with a nonjudgmental shared focus. There are books with content about all sorts of topics that may be areas the child or youth have as life and career goals that may help them gain new ideas and confidence as well as knowledge and skills. Having clear ideas about future roles is a one way to reduce the chance of developing depression and even suicide.

Reading a book, ideally illuminated by a warm colored light, assists in falling asleep, a huge issue for many youth. This is valuable in itself as inadequate sleep is a large contributor to worsening of many mental conditions. In contrast, the blue light from computer screens makes it harder to fall asleep. When reading a book is a bedtime habit, just as for babies and toddlers and whether read to by a parent (no age is too old!) or reading alone, the routine itself helps prepare the brain to transition into sleep.
 

Encouraging good habits

But how can parents get their children away from scanning the Internet to reading books? The American Academy of Pediatrics suggests setting time blocks for the day designated for school, exercise, homework, media, and sleep with a goal of a healthy balance. Reading could be added to the family’s plan. Making reading in the same room with parents as a regular habit both models reading (as parents have to get offline, too!) and sets up an opportunity to ask questions and converse about the reading materials, thereby building family relationships. Children are notorious for being recalcitrant about talking “about their day” when coming home from school. Having a less personal and intrusive subject to talk about creates a favorable setting for precious parent-child discussions. Some families read aloud to each other. This comes up naturally when reading a clip from a newspaper or magazine. It is especially valuable and inclusive for younger children who may not yet be able to read that level of material.

Getting creative

Some other strategies to promote reading include bringing books, magazines, or even comics with subjects that interest the child or youth into the house and leaving them around without comment. Getting started on a book series (Nancy Drew, Harry Potter, etc.) that is captivating provides extra incentive. Parents can talk about their favorites from their childhood, some of which are timeless! Families may need to be creative and find literature about the online characters from video games or movies that already interest their child, even if those are not seen as ideal learning material. Not commenting on the presence of the reading material takes the pressure off and makes it clear that it is their choice whether to read them or not.

Books need to be seen as a gift rather than a “penalty” for being online. Visiting a bookstore together or giving a gift certificate for books are other ways a parent can support reading while indicating that the youth has choice. There are now more than 150,000 Little Free Library locations worldwide (visible on the app) where books can be obtained 24/7 at no cost. Bringing books to donate or even joining the cause and becoming a steward of one of these pop-up libraries models high valuation of reading but is also a volunteer activity of which the child can be proud. We brought our children’s old books to our pediatric practice and encouraged patients to “bring one and take one.” Of course, the public library is often an option and is free. Another advantage of the library is that librarians and other children there may make suggestions of books that are popular with children their age. There are lots of specific suggestions online as well.

We need to be aware that children who resist reading books may have reading weaknesses. We can assess reading fluency with standard Gray Oral Reading paragraphs or the Wide Range Achievement test in the office or recommend a reading assessment by the school. Parents who already know that their child has a reading problem may be getting advice from teachers or tutors on how to help. But to promote reading that is not onerous for a child with a reading disability, parents can do more reading aloud at home, offer audiobooks or podcasts at home or play them while driving, and aim for books with a lower reading level. Teachers or librarians can make suggestions. It is important for family members to not be judgmental about a child’s choice of reading materials.

We do not need to feel helpless in the face of the Internet – we can recommend more reading!

Women with moderate to severe psoriasis had a lower fertility rate, compared with age-matched peers without psoriasis, and overall, those with psoriasis had a slightly higher risk of pregnancy loss, compared with those who did not have the disease, in a U.K. cohort study.

Those are key findings from what is believed to be one of the largest studies to investigate fertility and obstetric outcomes in patients with psoriasis.

“Studies that have examined fertility and pregnancy outcomes in women with psoriasis have reported conflicting findings,” lead author Teng-Chou Chen, PhD, of the Centre for Pharmacoepidemiology and Drug Safety at the University of Manchester (England), and colleagues from the Global Psoriasis Atlas wrote in the study, published in JAMA Dermatology. Most of the studies were small, with under 100 women, “and are thus likely underpowered to detect a difference in pregnancy outcomes. The majority of those studies used disease registry data or lacked a matched comparison group and hence were unable to estimate the association of fertility and adverse pregnancy outcomes in women with psoriasis when compared with the general population.”

To determine fertility rates and birth outcomes in female patients with psoriasis, compared with age- and practice-matched patients without psoriasis, the researchers evaluated EHR data from a large U.K. primary care database, the Clinical Practice Research Datalink GOLD, from 1998 to 2019. They limited the analysis to patients aged 15-44 years and used relevant codes from clinical consultations to identify those with psoriasis. Then, for each patient with psoriasis, the researchers selected five comparators without psoriasis from the same primary care practice and matched for year of birth.

Both sets of patients were followed from the index date to age 45 years, death, transfer out of practice, last date of data collection, or end of the study period (Dec. 31, 2019), whichever came first. Pregnancy records were extracted for both sets of patients, and birth outcomes were categorized as pregnancy loss, live birth, stillbirth, and preterm birth. Adverse pregnancy outcomes were also collected. Finally, Dr. Chen and colleagues used a negative binomial model to examine the association between psoriasis and the fertility rate, and they applied logistic regression to compare the association between psoriasis and obstetric outcomes.

The analysis included 63,681 patients with psoriasis and 318,405 comparators whose median age on the index date was 30 years and who were followed for a median of 4.1 years. Among patients with psoriasis, 5.1% met criteria for moderate to severe disease in the follow-up period. The researchers observed that, compared with their age- and practice-matched counterparts, patients with psoriasis were more likely to be current smokers, alcohol drinkers, or overweight on the index date. They were also more often diagnosed with diabetes, hypertension, inflammatory bowel disease, thyroid disorders, and respiratory diseases such as asthma and chronic obstructive pulmonary disease.

Fertility, birth outcomes

When they looked at fertility outcomes, the researchers found that, compared with their matched peers without psoriasis, those with psoriasis had higher rates of fertility (risk ratio, 1.30; 95% confidence interval, 1.27-1.33; P < .001). But after the researchers stratified patients based on psoriasis severity, those with moderate to severe disease had significantly lower rates of fertility (RR, 0.75; 95% CI, 0.69-0.83; P < .001), compared those who did not have psoriasis.

As for adverse birth outcomes, compared with their matched comparators, pregnancies in patients with psoriasis were less likely to end in a live birth (odds ratio, 0.91; 95% CI, 0.88-0.93; P < .001). They also had a higher risk of pregnancy loss (OR, 1.06; 95% CI, 1.03-1.10; P < .001), most during the first trimester, at a gestation period of under 91 days.

In addition to psoriasis, patients younger than age 20 (OR, 2.04; 95% CI, 1.94-2.15; P < .011) and those aged between 20 and 24 years (OR, 1.35; 95% CI, 1.31-1.40; P < .001) had a higher risk of pregnancy loss, compared with those aged between 25 and 34 years.

However, no increases in the risks of antenatal hemorrhage, preeclampsia, or gestational diabetes were observed in patients with psoriasis, and no statistically significant differences in the odds of stillbirth and preterm birth were found between patients with psoriasis and matched comparators who did not have psoriasis.

“The mechanism to link the higher risk of pregnancy loss in patients with psoriasis is not clear, but there might be potential explanations,” the researchers wrote. “Psoriasis is characterized by the increased activity of [interleukin]-17, IL-23, and tumor necrosis factor–alpha. Those proinflammatory cytokines may negatively affect the placenta and cause impaired fetal growth.”

They recommended that further studies “evaluate the effects of better management of psoriasis and close monitoring during pregnancy on pregnancy loss.” In particular, “patients with psoriasis were more likely to have comorbidities that may be related to poor pregnancy outcomes, and hence increased emphasis of managing comorbidities as part of the routine management plan is also warranted.”

Asked to comment on the study, Alexa B. Kimball, MD, MPH, who has been involved with research on this topic, said that she and other investigators had observed some years ago that fertility rates for women with moderate to severe psoriasis might be lower than expected.

This trend was observed in some psoriasis registries, some pregnancy registries, and in clinical practice, Dr. Kimball, professor of dermatology at Harvard Medical School, Boston, said in an interview. “This study clearly demonstrates that lower fertility rates in the moderate to severe psoriasis population occurs and compels further exploration of the reason why.” The reasons could be biologic, she continued, including difficulty conceiving or an increased risk of miscarriage, sociobehavioral issues, or a combination.

“Behavioral examples could include that some women with moderate to severe psoriasis can flare during pregnancy, which might affect their choice” to become pregnant, Dr. Kimball said. “Stigma may also play a role in how women with moderate to severe psoriasis form relationships. Now that there are much better treatments for moderate to severe psoriasis and better knowledge about managing psoriasis during pregnancy, it will also be important to explore whether these trends change over time.”

The study was funded by the International League of Dermatological Societies on behalf of the Global Psoriasis Atlas. Two of the study authors reported receiving consulting fees and grant support from many pharmaceutical companies. Dr. Kimball disclosed that she serves or has served on several Organization of Teratology Information Specialists advisory board pregnancy registries, is a consultant and investigator for Abbvie, Janssen, Lilly, Bristol-Myers Squibb, Moonlake, UCB, and Amgen; has fellowship funding from Janssen; and serves on the board of Almirall.

Now that there are much better treatments for moderate to severe psoriasis and better knowledge about managing psoriasis during pregnancy, it will also be important to explore whether these trends change over time.”

The study was funded by the International League of Dermatological Societies on behalf of the Global Psoriasis Atlas. Two of the study authors reported receiving consulting fees and grant support from many pharmaceutical companies. Dr. Kimball disclosed that she serves or has served on several Organization of Teratology Information Specialists advisory board pregnancy registries, is a consultant and investigator for Abbvie, Janssen, Lilly, Bristol-Myers Squibb, Moonlake, UCB, and Amgen; has fellowship funding from Janssen; and serves on the board of Almirall.

Women with moderate to severe psoriasis had a lower fertility rate, compared with age-matched peers without psoriasis, and overall, those with psoriasis had a slightly higher risk of pregnancy loss, compared with those who did not have the disease, in a U.K. cohort study.

Those are key findings from what is believed to be one of the largest studies to investigate fertility and obstetric outcomes in patients with psoriasis.

“Studies that have examined fertility and pregnancy outcomes in women with psoriasis have reported conflicting findings,” lead author Teng-Chou Chen, PhD, of the Centre for Pharmacoepidemiology and Drug Safety at the University of Manchester (England), and colleagues from the Global Psoriasis Atlas wrote in the study, published in JAMA Dermatology. Most of the studies were small, with under 100 women, “and are thus likely underpowered to detect a difference in pregnancy outcomes. The majority of those studies used disease registry data or lacked a matched comparison group and hence were unable to estimate the association of fertility and adverse pregnancy outcomes in women with psoriasis when compared with the general population.”

To determine fertility rates and birth outcomes in female patients with psoriasis, compared with age- and practice-matched patients without psoriasis, the researchers evaluated EHR data from a large U.K. primary care database, the Clinical Practice Research Datalink GOLD, from 1998 to 2019. They limited the analysis to patients aged 15-44 years and used relevant codes from clinical consultations to identify those with psoriasis. Then, for each patient with psoriasis, the researchers selected five comparators without psoriasis from the same primary care practice and matched for year of birth.

Both sets of patients were followed from the index date to age 45 years, death, transfer out of practice, last date of data collection, or end of the study period (Dec. 31, 2019), whichever came first. Pregnancy records were extracted for both sets of patients, and birth outcomes were categorized as pregnancy loss, live birth, stillbirth, and preterm birth. Adverse pregnancy outcomes were also collected. Finally, Dr. Chen and colleagues used a negative binomial model to examine the association between psoriasis and the fertility rate, and they applied logistic regression to compare the association between psoriasis and obstetric outcomes.

The analysis included 63,681 patients with psoriasis and 318,405 comparators whose median age on the index date was 30 years and who were followed for a median of 4.1 years. Among patients with psoriasis, 5.1% met criteria for moderate to severe disease in the follow-up period. The researchers observed that, compared with their age- and practice-matched counterparts, patients with psoriasis were more likely to be current smokers, alcohol drinkers, or overweight on the index date. They were also more often diagnosed with diabetes, hypertension, inflammatory bowel disease, thyroid disorders, and respiratory diseases such as asthma and chronic obstructive pulmonary disease.

Fertility, birth outcomes

When they looked at fertility outcomes, the researchers found that, compared with their matched peers without psoriasis, those with psoriasis had higher rates of fertility (risk ratio, 1.30; 95% confidence interval, 1.27-1.33; P < .001). But after the researchers stratified patients based on psoriasis severity, those with moderate to severe disease had significantly lower rates of fertility (RR, 0.75; 95% CI, 0.69-0.83; P < .001), compared those who did not have psoriasis.

As for adverse birth outcomes, compared with their matched comparators, pregnancies in patients with psoriasis were less likely to end in a live birth (odds ratio, 0.91; 95% CI, 0.88-0.93; P < .001). They also had a higher risk of pregnancy loss (OR, 1.06; 95% CI, 1.03-1.10; P < .001), most during the first trimester, at a gestation period of under 91 days.

In addition to psoriasis, patients younger than age 20 (OR, 2.04; 95% CI, 1.94-2.15; P < .011) and those aged between 20 and 24 years (OR, 1.35; 95% CI, 1.31-1.40; P < .001) had a higher risk of pregnancy loss, compared with those aged between 25 and 34 years.

However, no increases in the risks of antenatal hemorrhage, preeclampsia, or gestational diabetes were observed in patients with psoriasis, and no statistically significant differences in the odds of stillbirth and preterm birth were found between patients with psoriasis and matched comparators who did not have psoriasis.

“The mechanism to link the higher risk of pregnancy loss in patients with psoriasis is not clear, but there might be potential explanations,” the researchers wrote. “Psoriasis is characterized by the increased activity of [interleukin]-17, IL-23, and tumor necrosis factor–alpha. Those proinflammatory cytokines may negatively affect the placenta and cause impaired fetal growth.”

They recommended that further studies “evaluate the effects of better management of psoriasis and close monitoring during pregnancy on pregnancy loss.” In particular, “patients with psoriasis were more likely to have comorbidities that may be related to poor pregnancy outcomes, and hence increased emphasis of managing comorbidities as part of the routine management plan is also warranted.”

Asked to comment on the study, Alexa B. Kimball, MD, MPH, who has been involved with research on this topic, said that she and other investigators had observed some years ago that fertility rates for women with moderate to severe psoriasis might be lower than expected.

This trend was observed in some psoriasis registries, some pregnancy registries, and in clinical practice, Dr. Kimball, professor of dermatology at Harvard Medical School, Boston, said in an interview. “This study clearly demonstrates that lower fertility rates in the moderate to severe psoriasis population occurs and compels further exploration of the reason why.” The reasons could be biologic, she continued, including difficulty conceiving or an increased risk of miscarriage, sociobehavioral issues, or a combination.

“Behavioral examples could include that some women with moderate to severe psoriasis can flare during pregnancy, which might affect their choice” to become pregnant, Dr. Kimball said. “Stigma may also play a role in how women with moderate to severe psoriasis form relationships. Now that there are much better treatments for moderate to severe psoriasis and better knowledge about managing psoriasis during pregnancy, it will also be important to explore whether these trends change over time.”

Frailty is an age-associated, nonspecific vulnerability to adverse health outcomes. Frailty can also be described as a complex of symptoms characterized by impaired stress tolerance due to a decline in the functionality of different organs.¹ The prevalence of frailty varies widely depending on the method of measurement and the population studied.^2-4 It is a nonconstant factor that increases with age. A deficit accumulation frailty index (FI) is one method used to measure frailty.⁵ This approach sees frailty as a multidimensional risk state measured by quantity rather than the nature of health concerns. A deficit accumulation FI does not require physical testing but correlates well with other phenotypic FIs.⁶ It is, however, time consuming, as ≥ 30 deficits need to be measured to offer greater stability to the frailty estimate.

Health care is seeing increasing utilization of big data analytics to derive predictive models and help with resource allocation. There are currently 2 existing automated tools to predict health care utilization and mortality at the US Department of Veterans Affairs (VA): the VA Frailty Index (VA-FI-10) and the Care Assessment Need (CAN). VA-FI-10 is an International Statistical Classification of Diseases, Tenth Revision (ICD-10) update of the VA-FI that was created in March 2021. The VA-FI-10 is a claims-based frailty assessment tool using 31 health deficits. Calculating the VA-FI-10 requires defining an index date and lookback period (typically 3 years) relative to which it will be calculated.⁷

CAN is a set of risk-stratifying statistical models run on veterans receiving VA primary care services as part of a patient aligned care team (PACT) using electronic health record data.⁸ Each veteran is stratified based on the individual’s risks of hospitalization, death, and hospitalization or death. These 3 events are predicted for 90-day and 1-year time periods for a total of 6 distinct outcomes. CAN is currently on its third iteration (CAN 2.5) and scores range from 0 (low) to 99 (high). CAN scores are updated weekly. The 1-year hospitalization probabilities for all patients range from 0.8% to 93.1%. For patients with a CAN score of 50, the probability of being hospitalized within a year ranges from 4.5% to 5.2%, which increases to 32.2% to 36% for veterans with a CAN score of 95. The probability range widens significantly (32.2%-93.1%) for patients in the top 5 CAN scores (95-99).

CAN scores are a potential screening tool for frailty among older adults; they are generated automatically and provide acceptable diagnostic accuracy. Hence, the CAN score may be a useful tool for primary care practitioners for the detection of frailty in their patients. The CAN score has shown a moderate positive association with the FRAIL Scale.^9,10 The population-based studies that have used the FI approach (differing FIs, depending on the data available) give robust results: People accumulate an average of 0.03 deficits per year after the age of 70 years.¹¹ Interventions to delay or reverse frailty have not been clearly defined with heterogeneity in the definition of frailty and measurement of frailty outcomes.^12,13 The prevalence of frailty in the veteran population is substantially higher than the prevalence in community populations with a similar age distribution. There is also mounting evidence that veterans accumulate deficits more rapidly than their civilian counterparts.¹⁴

COVID-19 was declared a pandemic in March 2020 and had many impacts on global health that were most marked in the first year. These included reductions in hospital visits for non-COVID-19 health concerns, a reduction in completed screening tests, an initial reduction in other infectious diseases (attributable to quarantines), and an increase or worsening of mental health concerns.^15,16

We aimed to investigate whether frailty increased disproportionately in a subset of older veterans in the first year of the COVID-19 pandemic when compared with the previous year using CAN scores. This single institution, longitudinal cohort study was determined to be exempt from institutional review board review but was approved by the Phoenix VA Health Care System (PVAHCS) Research and Development Committee.

Methods

The Office of Clinical Systems Development and Evaluation (CSDE–10E2A) produces a weekly CAN Score Report to help identify the highest-risk patients in a primary care panel or cohort. CAN scores range from 0 (lowest risk) to 99 (highest risk), indicating how likely a patient is to experience hospitalization or death compared with other VA patients. CAN scores are calculated with statistical prediction models that use data elements from the following Corporate Data Warehouse (CDW) domains: demographics, health care utilization, laboratory tests, medical conditions, medications, and vital signs (eAppendix available online at 10.12788/fp.0385).

The CAN Score Report is generated weekly and stored on a CDW server. A patient will receive all 6 distinct CAN scores if they are: (1) assigned to a primary care PACT on the risk date; (2) a veteran; (3) not hospitalized in a VA facility on the risk date; and (4) alive as of the risk date. New to CAN 2.5 is that patients who meet criteria 1, 2, and 4 but are hospitalized in a VA facility on the risk date will receive CAN scores for the 1-year and 90-day mortality models.

Utilizing VA Informatics and Computing Infrastructure (VA HSR RES 13-457, US Department of Veterans Affairs [2008]), we obtained 2 lists of veterans aged 70 to 75 years on February 8, 2019, with a calculated CAN score of ≥ 75 for 1-year mortality and 1-year hospitalization on that date. A veteran with a CAN score of ≥ 75 is likely to be prefrail or frail.^9,10 Veterans who did not have a corresponding calculated CAN score on February 7, 2020, and February 12, 2021, were excluded. COVID-19 was declared a public health emergency in the United States on January 31, 2020, and the World Health Organization declared COVID-19 a pandemic on March 11, 2020.¹⁷ We picked February 7, 2020, within this time frame and without any other special significance. We picked additional CAN score calculation dates approximately 1 year prior and 1 year after this date. Veterans had to be alive on February 12, 2021, (the last date of the CAN score) to be included in the cohorts.

Statistical Analyses

The difference in CAN score from one year to the next was calculated for each patient. The difference between 2019 and 2020 was compared with the difference between 2020 to 2021 using a paired t test. Yearly CAN score values were analyzed using repeated measures analysis of variance. The number of patients that showed an increase in CAN score (ie, increased risk of either mortality or hospitalization within the year) or a decrease (lower risk) was compared using the χ² test. IBM SPSS v26 and GraphPad Prism v18 were used for statistical analysis. P < .05 was considered statistically significant.

Results

There were 3538 veterans at PVAHCS who met the inclusion criteria and had a 1-year mortality CAN score ≥ 75 on February 8, 2019.

In the hospitalization group, there were 6046 veterans in the analysis; 57 veterans missing a 1-year hospitalization CAN score that were excluded. The mean age was 71.7 (1.3) years and included 5874 male (97.2%) and 172 female (2.8%) veterans. There was a decline in mean 1-year hospitalization CAN scores in our subset of frail older veterans by 2.8 (95% CI, -3.1 to -2.6) in the year preceding the COVID-19 pandemic. This mean decline slowed significantly to 1.5 (95% CI, -1.8 to -1.2; P < .0001) after the first year of the COVID-19 pandemic. Mean CAN scores for 1-year hospitalization were 84.6 (95% CI, 84.4 to 84.8), 81.8 (95% CI, 81.5 to 82.1), and 80.2 (95% CI, 79.9 to 80.6) for 2019, 2020, and 2021, respectively.

We also calculated the number of veterans with increasing, stable, and decreasing CAN scores across each of our defined periods in both the 1-year mortality and hospitalization groups.

Discussion

We studied frailty trends in an older veteran subpopulation enrolled at the PVAHCS 1 year prior and into the COVID-19 pandemic using CAN scores. Frailty is a dynamic state. Previous frailty assessments aimed to identify patients at the highest risk of death. With the advent of advanced therapeutics for several diseases, the number of medical conditions that are now managed as chronic illnesses continues to grow. There is a role for repeated measures of frailty to try to identify frailty trends.¹⁹ These trends may assist us in resource allocation, identifying interventions that work and those that do not.

Some studies have shown an overall declining lethality of frailty. This may reflect improvements in the care and management of chronic conditions, screening tests, and increased awareness of healthy lifestyles.²⁰ Another study of frailty trajectories in a veteran population in the 5 years preceding death showed multiple trajectories (stable, gradually increasing, rapidly increasing, and recovering).¹⁹

The PACT is a primary care model implemented at VA medical centers in April 2010. It is a patient-centered medical home model (PCMH) with several components. The VA treats a population of socioeconomically vulnerable patients with complex chronic illness management needs. Some of the components of a PACT model relevant to our study include facilitated self-management support for veterans in between practitioner visits via care partners, peer-to-peer and transitional care programs, physical activity and diet programs, primary care mental health, integration between primary and specialty care, and telehealth.²¹ A previous study has shown that VA primary care clinics with the most PCMH components in place had greater improvements in several chronic disease quality measures than in clinics with a lower number of PCMH components.²²

Limitations

Our study is limited by our older veteran population demographics. We chose only a subset of older veterans at a single VA center for this study and cannot extrapolate the results to all older frail veterans or community dwelling older adults. Robust individuals may also transition to prefrailty and frailty over longer periods; our study monitored frailty trends over 2 years.

CAN scores are not quality measures to improve upon. Allocation and utilization of additional resources may clinically benefit a patient but increase their CAN scores. Although our results are statistically significant, we are unable to make any conclusions about clinical significance.

Conclusions

Our study results indicate frailty as determined by 1-year mortality CAN scores significantly increased in a subset of older veterans during the first year of the COVID-19 pandemic when compared with the previous year. Whether this change in frailty is temporary or long lasting remains to be seen. Automated CAN scores can be effectively utilized to monitor frailty trends in certain veteran populations over longer periods.

CAN scores are calculated with statistical prediction models that use data elements from the following Corporate Data Warehouse (CDW) domains: demographics, health care utilization, laboratory tests, medical conditions, medications, and vital signs (eAppendix available online at 10.12788/fp.0385).

The CAN Score Report is generated weekly and stored on a CDW server. A patient will receive all 6 distinct CAN scores if they are: (1) assigned to a primary care PACT on the risk date; (2) a veteran; (3) not hospitalized in a VA facility on the risk date; and (4) alive as of the risk date. New to CAN 2.5 is that patients who meet criteria 1, 2, and 4 but are hospitalized in a VA facility on the risk date will receive CAN scores for the 1-year and 90-day mortality models.

Utilizing VA Informatics and Computing Infrastructure (VA HSR RES 13-457, US Department of Veterans Affairs [2008]), we obtained 2 lists of veterans aged 70 to 75 years on February 8, 2019, with a calculated CAN score of ≥ 75 for 1-year mortality and 1-year hospitalization on that date. A veteran with a CAN score of ≥ 75 is likely to be prefrail or frail.^9,10 Veterans who did not have a corresponding calculated CAN score on February 7, 2020, and February 12, 2021, were excluded. COVID-19 was declared a public health emergency in the United States on January 31, 2020, and the World Health Organization declared COVID-19 a pandemic on March 11, 2020.¹⁷ We picked February 7, 2020, within this time frame and without any other special significance. We picked additional CAN score calculation dates approximately 1 year prior and 1 year after this date. Veterans had to be alive on February 12, 2021, (the last date of the CAN score) to be included in the cohorts.

Statistical Analyses

The difference in CAN score from one year to the next was calculated for each patient. The difference between 2019 and 2020 was compared with the difference between 2020 to 2021 using a paired t test. Yearly CAN score values were analyzed using repeated measures analysis of variance. The number of patients that showed an increase in CAN score (ie, increased risk of either mortality or hospitalization within the year) or a decrease (lower risk) was compared using the χ² test. IBM SPSS v26 and GraphPad Prism v18 were used for statistical analysis. P < .05 was considered statistically significant.

Results

There were 3538 veterans at PVAHCS who met the inclusion criteria and had a 1-year mortality CAN score ≥ 75 on February 8, 2019.

In the hospitalization group, there were 6046 veterans in the analysis; 57 veterans missing a 1-year hospitalization CAN score that were excluded. The mean age was 71.7 (1.3) years and included 5874 male (97.2%) and 172 female (2.8%) veterans. There was a decline in mean 1-year hospitalization CAN scores in our subset of frail older veterans by 2.8 (95% CI, -3.1 to -2.6) in the year preceding the COVID-19 pandemic. This mean decline slowed significantly to 1.5 (95% CI, -1.8 to -1.2; P < .0001) after the first year of the COVID-19 pandemic. Mean CAN scores for 1-year hospitalization were 84.6 (95% CI, 84.4 to 84.8), 81.8 (95% CI, 81.5 to 82.1), and 80.2 (95% CI, 79.9 to 80.6) for 2019, 2020, and 2021, respectively.

We also calculated the number of veterans with increasing, stable, and decreasing CAN scores across each of our defined periods in both the 1-year mortality and hospitalization groups.

Discussion

We studied frailty trends in an older veteran subpopulation enrolled at the PVAHCS 1 year prior and into the COVID-19 pandemic using CAN scores. Frailty is a dynamic state. Previous frailty assessments aimed to identify patients at the highest risk of death. With the advent of advanced therapeutics for several diseases, the number of medical conditions that are now managed as chronic illnesses continues to grow. There is a role for repeated measures of frailty to try to identify frailty trends.¹⁹ These trends may assist us in resource allocation, identifying interventions that work and those that do not.

Some studies have shown an overall declining lethality of frailty. This may reflect improvements in the care and management of chronic conditions, screening tests, and increased awareness of healthy lifestyles.²⁰ Another study of frailty trajectories in a veteran population in the 5 years preceding death showed multiple trajectories (stable, gradually increasing, rapidly increasing, and recovering).¹⁹

The PACT is a primary care model implemented at VA medical centers in April 2010. It is a patient-centered medical home model (PCMH) with several components. The VA treats a population of socioeconomically vulnerable patients with complex chronic illness management needs. Some of the components of a PACT model relevant to our study include facilitated self-management support for veterans in between practitioner visits via care partners, peer-to-peer and transitional care programs, physical activity and diet programs, primary care mental health, integration between primary and specialty care, and telehealth.²¹ A previous study has shown that VA primary care clinics with the most PCMH components in place had greater improvements in several chronic disease quality measures than in clinics with a lower number of PCMH components.²²

Limitations

Our study is limited by our older veteran population demographics. We chose only a subset of older veterans at a single VA center for this study and cannot extrapolate the results to all older frail veterans or community dwelling older adults. Robust individuals may also transition to prefrailty and frailty over longer periods; our study monitored frailty trends over 2 years.

CAN scores are not quality measures to improve upon. Allocation and utilization of additional resources may clinically benefit a patient but increase their CAN scores. Although our results are statistically significant, we are unable to make any conclusions about clinical significance.

Conclusions

Our study results indicate frailty as determined by 1-year mortality CAN scores significantly increased in a subset of older veterans during the first year of the COVID-19 pandemic when compared with the previous year. Whether this change in frailty is temporary or long lasting remains to be seen. Automated CAN scores can be effectively utilized to monitor frailty trends in certain veteran populations over longer periods.

Pyogenic hepatic abscess (PHA) is a collection of pus in the liver caused by bacterial infection of the liver parenchyma. This potentially life-threatening condition has a mortality rate reported to be as high as 47%.¹ The incidence of PHA is reported to be 2.3 per 100,000 individuals and is more common in immunosuppressed individuals and those with diabetes mellitus, cancer, and liver transplant.^2,3 PHA infections are usually polymicrobial and most commonly include enteric organisms like Escherichia coli and Klebsiella pneumoniae.⁴

We present a rare cause of PHA with Fusobacterium nucleatum (F nucleatum) in an immunocompetent patient with poor oral health, history of diverticulitis, and recent COVID-19 infection whose only symptoms were chest pain and a 4-week history of fever and malaise.

Case Presentation

A 52-year-old man initially presented to the C.W. Bill Young Veterans Affairs Medical Center (CWBYVAMC) emergency department in Bay Pines, Florida, for fever, malaise, and right-sided chest pain on inspiration. The fever and malaise began while he was on vacation 4 weeks prior. He originally presented to an outside hospital where he tested positive for COVID-19 and was recommended ibuprofen and rest. His symptoms did not improve, and he returned a second time to the outside hospital 2 weeks later and was diagnosed with pneumonia and placed on outpatient antibiotics. The patient subsequently returned to CWBYVAMC 2 weeks after starting antibiotics when he began to develop right-sided inspiratory chest pain. He reported no other recent travel and no abdominal pain. The patient’s history was significant for diverticulitis 2 years before. A colonoscopy was performed during that time and showed no masses.

On presentation, the patient was febrile with a temperature of 100.8 °F; otherwise, his vital signs were stable. Physical examinations, including abdominal, respiratory, and cardiovascular, were unremarkable. The initial laboratory workup revealed a white blood cell (WBC) count of 18.7 K/μL (reference range, 5-10 K/μL) and microcytic anemia with a hemoglobin level of 8.8 g/dL. The comprehensive metabolic panel revealed normal aspartate transaminase, alanine transaminase, and total bilirubin levels and elevated alkaline phosphatase of 215 U/L (reference range, 44-147 U/L), revealing possible mild intrahepatic cholestasis. Urinalysis showed trace proteinuria and urobilinogen. Coagulation studies showed elevated D-dimer and procalcitonin levels at 1.9 ng/mL (reference range, < 0.1 ng/mL) and 1.21 ng/mL (reference range, < 0.5 ng/mL), respectively, with normal prothrombin and partial thromboplastin times. The patient had a normal troponin, fecal, and blood culture; entamoeba serology was negative.

A computed tomograph (CT) angiography of the chest was performed to rule out pulmonary embolism, revealing liver lesions suspicious for abscess or metastatic disease. Minimal pleural effusion was detected bilaterally. A subsequent CT confirmed the presence of hepatic lesions consistent with an abscess (Figure 1).

Discussion

F nucleatum is a gram-negative, nonmotile, spindle-shaped rod found in dental plaques.⁵ The incidence of F nucleatum bacteremia is 0.34 per 100,000 people and increases with age, with the median age being 53.5 years.⁶ Although our patient did not present with F nucleatum bacteremia, it is possible that bacteremia was present before hospitalization but resolved by the time the sample was drawn for culture. F nucleatum bacteremia can lead to a variety of presentations. The most common primary diagnoses are intra-abdominal infections (eg, PHA, respiratory tract infections, and hematological disorders).^1,6

PHA Presentation

The most common presenting symptoms of PHA are fever (88%), abdominal pain (79%), and vomiting (50%).⁴ The patient’s presentation of inspiratory right-sided chest pain is likely due to irritation of the diaphragmatic pleura of the right lung secondary to the abscess formation. The patient did not experience abdominal pain throughout the course of this disease or on palpation of his right upper quadrant. To our knowledge, this is the only case of PHA in the literature of a patient with inspiratory chest pain without respiratory infection, abdominal pain, and cardiac abnormalities. There was no radiologic evidence or signs of hypoxia on admission to CWBYVAMC, which makes respiratory infection an unlikely cause of the chest pain. Moreover, the patient presented with new-onset chest pain 2 weeks after the diagnosis of pneumonia.

Common laboratory findings of PHA include transaminitis, leukocytosis, and bilirubinemia.⁴ Of note, increased procalcitonin has also been associated with PHA and extreme elevation (> 200 μg/L) may be a useful biomarker to identify F nucleatum infections before the presence of leukocytosis.³ CT of PHA usually reveals right lobe involvement, and F nucleatum infection usually demonstrates multiple abscesses.^4,7

Contributing Factors in F nucleatum PHA

F nucleatum is associated with several oral diseases, such as periodontitis and gingivitis.⁸ It is important to do an oral inspection on patients with F nucleatum infections because it can spread from oral cavities to different body parts.

F nucleatum is also found in the gut.⁹ Any disease that can cause a break in the gastrointestinal mucosa may result in F nucleatum bacteremia and PHA. This may be why F nucleatum has been associated with a variety of different diseases, such as diverticulitis, inflammatory bowel disease, appendicitis, and colorectal cancer.^10,11 Our patient had a history of diverticulosis with diverticulitis. Bawa and colleagues described a patient with recurrent diverticulitis who developed F nucleatum bacteremia and PHA.¹¹ Our patient did not have any signs of diverticulitis.

Our patient’s COVID-19 infection also had a role in delaying the appropriate treatment of PHA. Without any symptoms of PHA, a diagnosis is difficult in a patient with a positive COVID-19 test, and treatment was delayed 1 month. Moreover, COVID-19 has been reported to delay the diagnosis of PHA even in the absence of a positive COVID-19 test. Collins and Diamond presented a patient during the COVID-19 pandemic who developed a periodontal abscess, which resulted in F nucleatum bacteremia and PHA due to delayed hospital presentation after the patient’s practitioners recommended self-isolation, despite a negative COVID-19 test.¹² This highlights the impact that COVID-19 may have on the timely diagnosis and treatment of patients with PHA.

Malignancy has been associated with F nucleatum bacteremia.^1,13 Possibly the association is due to gastrointestinal mucosa malignancy’s ability to cause micro-abrasions, resulting in F nucleatum bacteremia.¹⁰ Additionally, F nucleatum may promote the development of colorectal neoplasms.⁸ Due to this association, screening for colorectal cancer in patients with F nucleatum infection is important. In our patient, a colonoscopy was performed during the patient’s hospitalization for diverticulitis 2 years prior. No signs of colorectal neoplasm were noted

Conclusions

PHA due to F nucleatum is a rare but potentially life-threatening condition that must be diagnosed and treated promptly. It usually presents with fever, abdominal pain, and vomiting but can present with chest pain in the absence of a respiratory infection, cardiac abnormalities, and abdominal pain, as in our patient. A wide spectrum of infections can occur with F nucleatum, including PHA.

Suspicion for infection with this organism should be kept high in middle-aged and older individuals who present with an indolent disease course and have risk factors, such as poor oral health and comorbidities. Suspicion should be kept high even in the event of COVID-19 infection, especially in individuals with prolonged fever without other signs indicating respiratory infection. We believe that the most likely causes of this patient’s infection were his dental caries and periodontal disease. The timing of his symptoms is not consistent with his previous episode of diverticulitis. Due to the mortality of PHA, diagnosis and treatment must be prompt. Initial treatment with drainage and empiric anaerobic coverage is recommended, followed by a tailored antibiotic regiment if indicated by culture, and further drainage if suggested by imaging.

The US Coast Guard (USCG) operates within the US Department of Homeland Security during times of peace and represents a force of > 55,000 active-duty service members (ADSMs), civilians, and reservists. ADSMs account for about 40,000 USCG personnel. The missions of the USCG include activities such as maritime law enforcement (drug interdiction), search and rescue, and defense readiness.¹ Akin to other US Department of Defense (DoD) services, USCG ADSMs are required to maintain medical readiness to maximize operational success.

Whereas the DoD centralizes its health care services at military treatment facilities, USCG health care tends to be dispersed to smaller clinics and sickbays across large geographic areas. The USCG operates 42 clinics of varying sizes and medical capabilities, providing outpatient, dentistry, pharmacy, laboratory, radiology, physical therapy, optometry, and other health care services. Many ADSMs are evaluated by a USCG medical officer in these outpatient clinics, and ADSMs may choose to fill prescriptions at the in-house pharmacy if present at that clinic.

The USCG has 14 field pharmacists. In addition to the standard dispensing role at their respective clinics, USCG pharmacists provide regional oversight of pharmaceutical services for USCG units within their area of responsibility (AOR). Therefore, USCG pharmacists clinically, operationally, and logistically support these regional assets within their AOR while serving the traditional pharmacist role. USCG pharmacists have access to ADSM electronic health records (EHRs) when evaluating prescription orders, similar to other ambulatory care settings.

New recruits and accessions into the USCG are first screened for disqualifying health conditions, and ADSMs are required to maintain medical readiness throughout their careers.² Therefore, this population tends to be younger and overall healthier compared with the general population. Equally important, medication errors or inappropriate prescribing in the ADSM group could negatively affect their duty status and mission readiness of the USCG in addition to exposing the ADSM to medication-related harms.

Duty status is an important and unique consideration in this population. ADSMs are expected to be deployable worldwide and physically and mentally capable of executing all duties associated with their position. Duty status implications and the perceived ability to stand watch are tied to an ADMS’s specialty, training, and unit role. Duty status is based on various frameworks like the USCG Medical Manual, Aeromedical Policy Letters, and other governing documents.³ Duty status determinations are initiated by privileged USCG medical practitioners and may be executed in consultation with relevant commands and other subject matter experts. An inappropriately dosed antibiotic prescription, for example, can extend the duration that an ADSM would be considered unfit for full duty due to prolonged illness. Accordingly, being on a limited duty status may negatively affect USCG total mission readiness as a whole. USCG pharmacists play a vital role in optimizing ADSMs’ medication therapies to ensure safety and efficacy.

Currently no published literature explores the number of medication interventions or the impact of those interventions made by USCG pharmacists. This study aimed to quantify the number, duty status impact, and replicability of medication interventions made by one pharmacist at the USCG Base Alameda clinic over 6 months.

Methods

As part of a USCG quality improvement study, a pharmacist tracked all medication interventions on a spreadsheet at USCG Base Alameda clinic from July 1, 2021, to December 31, 2021. The study defined a medication intervention as a communication with the prescriber with the intention to change the medication, strength, dose, dosage form, quantity, or instructions. Each intervention was subcategorized as either a drug therapy problem (DTP) or a non-DTP intervention. Interventions were divided into 7 categories.

Each DTP intervention was evaluated in a retrospective chart review by a panel of USCG pharmacists to assess for duty status severity and replicability. For duty status severity, the panel reviewed the intervention after considering patient-specific factors and determined whether the original prescribing (had there not been an intervention) could have reasonably resulted in a change of duty status for the ADSM from a fit for full duty (FFFD) status to a different duty status (eg, fit for limited duty [FFLD]). This duty status review factored in potential impacts across multiple positions and billets, including aviators (pilots) and divers. In addition, the panel, whose members all have prior community pharmacy experience, assessed replicability by determining whether the same intervention could have reasonably been made in the absence of access to the patient EHR, as would be common in a community pharmacy setting.

Interventions without an identified DTP were considered non-DTP interventions. These interventions involved recommendations for a more cost-effective medication or a similar in stock therapeutic option to minimize delay of patient care. The spreadsheet also included the date, medication name, medication class, specific intervention made, outcome, and other descriptive comments.

Results

During the 6-month period, 1751 prescriptions were dispensed at USCG Base Alameda pharmacy with 116 interventions (7%).

Among the DTP interventions, 26 (41%) dealt with an inappropriate dose, 13 (20%) were for medication omission, 7 (11%) for inappropriate dosage form, and 6 (9%) for excess medication (Table 2).

Discussion

This study is novel in examining the impact of a pharmacist’s medication interventions in a USCG ambulatory care practice setting. A PubMed literature search of the phrases “Coast Guard AND pharmacy” or “Coast Guard AND pharmacy AND intervention” yielded no results specific to pharmacy interventions in a USCG setting. However, the 2021 implementation of the enterprise-wide MHS GENESIS EHR may support additional tracking and analysis tools in the future.

Pharmacist interventions have been studied in diverse patient populations and practice settings, and most conclude that pharmacists make meaningful interventions at their respective organizations.^4-7 Many of these studies were conducted at open-door health care systems, whereas USCG clinics serve ADSMs nearly exclusively. The ADSM population tends to be younger and healthier due to age requirements and medical accession and retention standards.

It is important to recognize the value of a USCG pharmacist in identifying and rectifying potential medication errors, particularly those that may affect the ability to stand duty for ADSMs. An example intervention includes changing the daily starting dose of citalopram from the ordered 30 mg to the intended 10 mg. Inappropriately prescribed medication regimens may increase the incidence of adverse effects or prolong duration to therapeutic efficacy, which impairs the ability to stand duty. There were 3 circumstances where the prescriber had ordered the medication for an incorrect ADSM that were rectified by the pharmacist. If left unchanged, these errors could negatively affect the ADSM’s overall health, well-being, and duty status.

The acceptance rate for interventions in this study was 96%. The literature suggests a highly variable acceptance rate of pharmacist interventions when examined across various practice settings, health systems, and geographic locations.^8-10 This study’s comparatively high rate could be due to the pharmacist-prescriber relationships at USCG clinics. By virtue of colocatation and teamwork initiatives, the pharmacist has the opportunity to develop positive rapport with physicians, physician assistants, and other clinic staff.

Having access to EHRs allowed the pharmacist to make 18 of the DTP interventions. Chart access is not unique to the USCG and is common in other ambulatory care settings. Those 18 interventions, such as reconciling a prescription ordered as fluticasone/salmeterol but recorded in the EHR as “will prescribe montelukast,” were deemed possible because of EHR access. Such interventions could potentially be lost if ADSMs solely received their pharmaceutical care elsewhere.

USCG uses independent duty health services technicians (IDHSs) who practice in settings where a medical officer is not present, such as at smaller sickbays or aboard Coast Guard cutters. In this study, an IDHS had mistakenly created a medication order for the medical officer to sign for bupropion SR, when the ADSM had been taking and was intended to continue taking bupropion XL. This order was signed off by the medical officer, but this oversight was identified and corrected by the pharmacist before dispensing. This indicates that there is a vital educational role that the USCG pharmacist fulfills when working with health care team members within the AOR.

Equally important to consider are the non-DTP interventions. In a military setting, minimizations of delay in care are a high priority. There were 34 instances where the pharmacist made an intervention to recommend a similar therapeutic medication that was in stock to ensure that the ADSM had timely access to the medication without the need for prior authorization. In the context of short-notice, mission-critical deployments that may last for multiple months, recognizing medication shortages or other inventory constraints and recommending therapeutic alternatives ensures that the USCG can maintain a ready posture for missions in addition to providing timely and quality patient care.

Saving about $1700 over 6 months is also important. While this was not explicitly evaluated in the study, prescribers may not be acutely aware of medication pricing. There are often significant price differences between different formulations of the same medication (eg, naproxen delayed-release vs tablets). Because USCG pharmacists are responsible for ordering medications and managing their regional budget within the AOR, they are best poised to make cost-savings recommendations. These interventions suggest that USCG pharmacists must continue to remain actively involved in the patient care team alongside physicians, physician assistants, nurses, and corpsmen. Throughout this setting and in so many others, patients’ health outcomes improve when pharmacists are more engaged in the pharmacotherapy care plan.

Limitations

Currently, the USCG does not publish ADSM demographic or health-related data, making it difficult to evaluate these interventions in the context of age, gender, or type of disease. Accordingly, potential directions for future research include how USCG pharmacists’ interventions are stratified by duty station and initial diagnosis. Such studies may support future models where USCG pharmacists are providing targeted education to prescribers based on disease or medication classes.

This analysis may have limited applicability to other practice settings even within USCG. Most USCG clinics have a limited number of medical officers; indeed, many have only one, and clinics with pharmacies typically have 1 to 5 medical officers aboard. USCG medical officers have a multitude of other duties, which may impact prescribing patterns and pharmacist interventions. Statistical analyses were limited by the dearth of baseline data or comparative literature. Finally, the assessment of DTP interventions’ impact did not use an official measurement tool like the US Department of Veterans Affairs’ Safety Assessment Code matrix.¹¹ Instead, the study used the internal USCG pharmacist panel for the fitness for duty consideration as the main stratification of the DTP interventions’ duty status severity, because maintaining medical readiness is the top priority for a USCG clinic.

Conclusions

The multifaceted role of pharmacists in USCG clinics includes collaborating with the patient care team to make pharmacy interventions that have significant impacts on ADSMs’ wellness and the USCG mission. The ADSMs of this nation deserve quality medical care that translates into mission readiness, and the USCG pharmacy force stands ready to support that goal.

The US Coast Guard (USCG) operates within the US Department of Homeland Security during times of peace and represents a force of > 55,000 active-duty service members (ADSMs), civilians, and reservists. ADSMs account for about 40,000 USCG personnel. The missions of the USCG include activities such as maritime law enforcement (drug interdiction), search and rescue, and defense readiness.¹ Akin to other US Department of Defense (DoD) services, USCG ADSMs are required to maintain medical readiness to maximize operational success.

Whereas the DoD centralizes its health care services at military treatment facilities, USCG health care tends to be dispersed to smaller clinics and sickbays across large geographic areas. The USCG operates 42 clinics of varying sizes and medical capabilities, providing outpatient, dentistry, pharmacy, laboratory, radiology, physical therapy, optometry, and other health care services. Many ADSMs are evaluated by a USCG medical officer in these outpatient clinics, and ADSMs may choose to fill prescriptions at the in-house pharmacy if present at that clinic.

The USCG has 14 field pharmacists. In addition to the standard dispensing role at their respective clinics, USCG pharmacists provide regional oversight of pharmaceutical services for USCG units within their area of responsibility (AOR). Therefore, USCG pharmacists clinically, operationally, and logistically support these regional assets within their AOR while serving the traditional pharmacist role. USCG pharmacists have access to ADSM electronic health records (EHRs) when evaluating prescription orders, similar to other ambulatory care settings.

New recruits and accessions into the USCG are first screened for disqualifying health conditions, and ADSMs are required to maintain medical readiness throughout their careers.² Therefore, this population tends to be younger and overall healthier compared with the general population. Equally important, medication errors or inappropriate prescribing in the ADSM group could negatively affect their duty status and mission readiness of the USCG in addition to exposing the ADSM to medication-related harms.

Duty status is an important and unique consideration in this population. ADSMs are expected to be deployable worldwide and physically and mentally capable of executing all duties associated with their position. Duty status implications and the perceived ability to stand watch are tied to an ADMS’s specialty, training, and unit role. Duty status is based on various frameworks like the USCG Medical Manual, Aeromedical Policy Letters, and other governing documents.³ Duty status determinations are initiated by privileged USCG medical practitioners and may be executed in consultation with relevant commands and other subject matter experts. An inappropriately dosed antibiotic prescription, for example, can extend the duration that an ADSM would be considered unfit for full duty due to prolonged illness. Accordingly, being on a limited duty status may negatively affect USCG total mission readiness as a whole. USCG pharmacists play a vital role in optimizing ADSMs’ medication therapies to ensure safety and efficacy.

Currently no published literature explores the number of medication interventions or the impact of those interventions made by USCG pharmacists. This study aimed to quantify the number, duty status impact, and replicability of medication interventions made by one pharmacist at the USCG Base Alameda clinic over 6 months.

Methods

As part of a USCG quality improvement study, a pharmacist tracked all medication interventions on a spreadsheet at USCG Base Alameda clinic from July 1, 2021, to December 31, 2021. The study defined a medication intervention as a communication with the prescriber with the intention to change the medication, strength, dose, dosage form, quantity, or instructions. Each intervention was subcategorized as either a drug therapy problem (DTP) or a non-DTP intervention. Interventions were divided into 7 categories.

Each DTP intervention was evaluated in a retrospective chart review by a panel of USCG pharmacists to assess for duty status severity and replicability. For duty status severity, the panel reviewed the intervention after considering patient-specific factors and determined whether the original prescribing (had there not been an intervention) could have reasonably resulted in a change of duty status for the ADSM from a fit for full duty (FFFD) status to a different duty status (eg, fit for limited duty [FFLD]).

Advances in technology, including ubiquitous access to the internet and the capacity to transfer high-resolution representative images, have facilitated the adoption of telepathology by laboratories worldwide.^1-5 Telepathology includes the use of telecommunication links that enable transmission of digital pathology images for primary diagnosis, quality assurance (QA), education, research, or second opinion diagnoses.³ This improvement has culminated in approvals by the US Food and Drug Administration (FDA) of whole slide imaging (WSI) systems for surgical pathology slides: specifically, the Philips IntelliSite Digital Pathology Solution in 2017 and the Leica Aperio AT2 DX in 2020.^6-8 However, the approvals do not include telecytology due to lack of whole slide multiplanar scanning at different planes of focus or z-stacking capabilities.⁷

Long-term trends in pathology, specifically the slow reduction in the number of practicing pathologists available in the workforce compared with the total served population, along with the social distancing imperatives and disruptions brought about by the COVID-19 pandemic have made telepathology implementation pertinent to continue and improve pathology practice.^8-10

Description and Definitions

The primary modes of telepathology (static image telepathology, robotic telepathology, video microscopy, WSI, and multimodality telepathology) have been defined by the American Telemedicine Association (ATA).² WSI has been particularly suited for telepathology due to the ability to view digital slides in high resolution at various magnifications. These image files can also be viewed and shared with ease with other observers. Also, they take a shorter time to view compared with the use of a robotic microscope.³

Selection, Validation, and Implementation

WSI platforms vary in their characteristics and have several parameters, including but not limited to batch scanning vs continuous or random-access processing, throughput volume capacities, scan speed, cost, manual vs automatic loading of slides, image quality, slide capacity, flexibility for different slide sizes/features, telepathology capabilities once slide scanned, z-stacking, and regulatory approval status.⁸ Selection of the WSI device is dependent on need and cost considerations. For example, use for frozen section requires faster scanning speed and does not generally require a high throughput scanner.

Validation of telepathology by the testing site demonstrates that the new system performs as expected for its intended clinical use before being put into service and that the digital slides produced are acceptable for clinical diagnostic interpretation.¹¹ The College of American Pathologists (CAP) established WSI validation guidelines are part of the published laboratory standard of care.^11-13 An appropriate validation enables the benefits of telepathology while mitigating the risks.

There are 3 major CAP recommendations for validation. First, ≥ 60 cases should be included for each use case being validated with 20 additional cases for relevant ancillary applications not included in the 60 cases. Second, diagnostic concordance (ideally ≥ 95%) should be established between digital and glass slides for the same observer. Third, there should be a 2-week washout period between the viewing of digital and glass slides (Table 2).^12,13

Guidelines from the ATA establish that telepathology systems should be validated for clinical use, including non-WSI platforms.² Published validations of other non-WSI platforms (such as by robotic or multimodality telepathology) have followed the structure proposed in the guidelines by CAP for validating WSI.^14,15

Ensuring that all relevant responsibilities (clinical, facility, technical, training, documentation/archiving, quality management, and operations related) for the use of telepathology are met is another aspect of validation and implementation.² Clinical responsibilities include an agreement between the sending (referring) and receiving (consulting) parties on the information to accompany the digital material.² From ATA clinical guidelines, this includes identification information, provision to the consulting pathologist of all relevant clinical data, provision to retrieve for access any needed and/or relevant diagnostic material, and responsibility by referrer that the correct image/metadata was sent.² Involved parties should be trained to manage the materials being transmitted.²

Facility responsibilities include maintaining the standard of care defined by the facility and regulatory agencies.² The maintenance of accreditation, adherence to licensure requirements, and proper management of privileges to practice telepathology are also important.² Technical responsibilities include ensuring a proper validation that meets the standard of care and covers use cases.^2,11-13

All processes, training, and competencies should be followed and documented per standard facility operating procedures.² ATA recommends that telepathology should result in a formal report for diagnostic consultations, maintain logs of telepathology interactions or disclaimer statements, and have an appropriate retention policy.² The CAP recommends digital images used for primary diagnosis should be kept for 10 years if the original glass slides are not available.¹⁶ Once implemented, telepathology reports must be incorporated into the pathology and laboratory medicine department’s quality management plan for both the technical performance of the telepathology system and diagnostic performance of the pathologists using the system.² Operations responsibilities include ensuring that the telepathology system is maintained according to vendor recommendations and regulatory standards. Appropriate provisions for space and associated needs should be developed in conjunction with the information technology team of the facility to ensure appropriate security, privacy, and regulatory compliance.²

Applications and Uses

Telecytology. Rapid real-time telecytology has been documented to be useful in rapid on-site evaluations (ROSE) of the adequacy of fine needle aspirations (FNA).^17-21 Nevertheless, current Medicare reimbursement is limited given that ROSE is cost prohibitive, time consuming, and affects productivity in cytology laboratories.^17,22,23 Estimates of the time to provide ROSE for 1 procedure without telecytology range from 48.7 to 56.2 minutes.^17,23 The use of telecytology significantly reduces pathologist ROSE time without losing quality to about 12 minutes, of which only an average of 7.5 minutes was spent by the cytopathologist for the ROSE diagnosis.^17-21 ROSE also can be used for distant and remote locations to improve patient care.^17-21 Multiple vendors provide real-time telecytology service. Innovations using smartphone adapters, digital cameras that could work as their own IP addresses, and connection with high-speed dedicated connections with viewing platforms on high-sensitivity monitors can facilitate ROSE to improve patient management.^24,25 The successful accurate use of ROSE has been described; however, there are currently no FDA-approved telepathology ROSE platforms.^17-19,21-25

To date, the FDA has not approved any telecytology whole slide scanner due to a lack of z-stacking capability in submitted scanners.^7,21 Not all whole slide scanners offer z-stacking, though even in those that do offer it, the time necessary to scan the entire slide with adequate z-stacking takes too long to be clinically acceptable for many situations involving ROSE.²¹ WSI has also been used to develop international consensus for cytologic samples.²⁶ Published recommendations for the validation of these other modalities before usage follow the spirit of the CAP guidelines (as far as multiple cases with high concordance rates) for validation of WSI for diagnostic purposes but vary on the exact number of slides and acceptable concordance rate.^21,27 For ROSE with a robotic microscope without any on-site cytology personnel, documented standardized training of nonpathology staff members, such as the radiologist or other physician performing the FNA procedure, may be needed to enable the performance of ROSE telecytology and ensure compliance with regulations.^2,21 Besides ROSE, there are published validations for telecytology in primary diagnosis and QA, indicating a role for telecytology for diagnosis for laboratories that have properly validated and implemented the laboratory-developed test.^28-30

Frozen section. Telepathology has significant potential to improve access to frozen section consultation.^5,31-33 Benefits to improving access to frozen section include providing frozen section consultation at remote or off-site locations, increasing access to subspecialty consultation, improving workflow by eliminating the need to travel off-site to the frozen section case, cost savings in staff work time, and providing educational opportunities for pathology trainees.^5,31-33 In our experience, WSI with real-time viewing of frozen section allows for the assessment of transplant tissues, which is an evaluation that generally occurs at night. Discrepancies from frozen section telepathology using WSI to the final diagnosis may occur and those specific to WSI could result from slide or image quality, internet connectivity, and lack of training in using the telepathology system.³² Other issues that may lead to discrepancies between the frozen section diagnosis and the final diagnosis may occur with the review of glass slides by light microscopy.³⁴ Appropriate performance of validation, training, implementation, and quality control for telepathology can help in reaping the benefits while mitigating the risks.² In a large study comparing frozen section evaluation by telepathology with light microscopy, the sensitivity and specificity of frozen section were comparable between telepathology and light microscopy with a trend toward greater sensitivity by telepathology (0.92 and 0.99 for telepathology vs 0.90 and 0.99 by light microscopy alone, sensitivity and specificity, respectively).³³

Other applications. Evidence for efficacy in surgical pathology diagnosis led to FDA approval of the Philips IntelliSite Digital Pathology in 2017 and the Leica Aperio AT2 DX in 2020 WSI platforms.^6-8 The use of WSI in surgical pathology has been successfully validated or used in clinical practice at several pathology laboratory settings with documented benefits in the literature for primary and secondary diagnoses, QA, research, and education.^6-8,35-45 Benefits of telepathology include improved ergonomics and access to real-time pathologic services in remote areas or during on-site pathologist absence and expert second opinions. Telepathology also may reduce risk of slide loss during transport, shortened turnaround time, reduced costs of operation through workflow efficiencies, better load balancing, improve virtual collaboration, and digital storage of slides that may be irreplaceable.^3-8,35-45 Telepathology also has been shown to be useful for education, improving access to learning materials and increasing quality instructional materials at a lower cost.⁴⁵ The increased ease of collaboration with remote experts and access to slide material for other pathologists improves QA capabilities.^3-8,35-45 The availability of virtual slides is expected to promote further research in telepathology and pathology due to the increased availability of virtual material to researchers.^1,5,46

Telehematology. Published validations have shown effectiveness for hematopathology specimens, such as the peripheral smear. Telehematology also has demonstrated potential in a laboratory after proper validation and implementation as a laboratory-developed test.^37,47-49

Telemicrobiology and Computer-Assisted Pathologic Diagnosis. Telemicrobiology also has been successfully used for clinical, educational, and QA purposes.⁵⁰ The digitalization of slides involved with telepathology enables further innovation in machine learning for computer-assisted pathologic diagnosis (CAPD), which is already being used clinically for cervical Pap smears.²⁰ An artificial intelligence (AI)–based algorithm analyzes the slides to identify cells of interest, which are presented to the cytopathologist for confirmation.²⁰ However, the expansion of CAPD to include a variety of specimen types or diagnostic situations as well as safely and effectively take initiative in completing an accurate automated diagnosis requires additional development.^20,51,52 One of the key factors for machine learning to develop AI is the provision of a corpus of data.^51,52 Public, open-source data sources have been limited in size while private proprietary sources have highly restricted and expensive access; to address this, there is a current effort to build the world’s largest public open-source digital pathology corpus at Temple University Hospital, which may help enable innovations in the future.⁵²

Long-Term Trends/Applications

The COVID-19 pandemic has been unprecedented not only in its widespread morbidity and mortality, but also for the significant socioeconomic, health, lifestyle, societal, and workspace changes.^53-57 Specifically, the pandemic has introduced not only a need for social distancing and staff quarantines to prevent the spread of infection, but also a reduction in the workforce due to the stresses of COVID-19 (also known as the Great Resignation).⁵⁵ Before the pandemic, there was an existing downtrend in the number of pathologists in the US workforce.^9-10,58,59 From 2007 to 2017, the number of active pathologists in the US declined by 17.5% despite the increasing national population, resulting in not only an absolute decrease in the number of pathologists, but also an increasing population served per pathologist ratio.⁵⁹ Since 2017, this downtrend has continued; given the increasing loss of active pathologists from the workforce and the decreasing training of new pathologists, this decrease shows no signs of reversing even as the impact of the COVID-19 pandemic has begun to wane.^9,10,58-60

The advantages of telepathology in enabling social distancing and reducing travel to remote sites are known.^3-7,17 Given these advantages, some medical centers in the US have previously successfully validated and implemented telepathology operations earlier during the COVID-19 pandemic to ease workflow and ensure continued operations.^56,57 The use of telepathology also helps in balancing workload and continuing pathology operations even in light of the workforce reduction as cases no longer need to be signed out on site with glass slides but instead can be signed out at a remote laboratory. Although the impact of the COVID-19 pandemic on operations is decreasing, the capabilities for social distancing and reducing travel remain important to both improve operations and ensure resiliency in response to similar potential events.^3-7,17,60

Considering the long-term trends, the lessons of the COVID-19 pandemic, and the potential for future pandemics or other disasters, telepathology’s validation and implementation remains a reasonable choice for pathology practices looking to improve. A variety of practices not just in the general population, but also among US Department of Veterans Affairs medical centers (VAMCs) and the US Department of Defense Military Health System treating a veteran population can benefit from telepathology where it has previously been reported to have been reliable or successfully implemented.^61-63 Although the veteran population differs from the general population in several characteristics, such as the severity of disease, coexisting morbidities, and other history, given proper validation and implementation, telepathology’s usefulness extends across different pathology practice settings.^35-43,61-66

Limitations of Telepathology

In telepathology’s current state, there are limitations despite its immense promise.^6,35 These include initial capital costs, the additional training requirement, the additional time necessary to scan slides, technical challenges (ie, laboratory information system integration, color calibration, display artifacts, potential for small particle scanner omissions, and information technology dependence), the potential for slower evaluation per slide compared with optical microscopes, limitations of slide imaging (ie, z-stacking or lack of polarization on digital pathology), and occupational concerns regarding eye strain with increased computer monitor usage (ie, computer vision syndrome).^6,35 In addition, there are few telepathology scanners with FDA approval for WSI.^6-8

The improving technology of telepathology has made these limitations surmountable, including faster slide scanning and increasing digital storage capacity for large WSI files. Due to this improvement in technology, an increasing number of laboratory settings, have adopted telepathology as its advantages have begun to outweigh the limitations.^2-5 Additionally, the proper validation performed before implementing telepathology can help laboratories identify their unique challenges, troubleshoot, and resolve the limitations before use in clinical care.^11-13 Continuing QA during its use and implementation is important to ensure that telepathology performs as expected for clinical purposes despite its limitations.²

Conclusions

Telepathology is a promising technology that may improve pathology practice once properly validated and implemented.^1-8 Though there are barriers to this validation and implementation, particularly the capital costs and training, there are several potential benefits, including increased productivity, cost savings, improvement in the workflow, enhanced access to pathologic consultation, and adaptability of the pathology laboratory in an era of a decreased workforce and social distancing due to the COVID-19 pandemic.^1-8,55-56 This potential applies across the wide spectrum of potential telepathology uses from frozen section, telecytology (including ROSE) to primary and second opinion diagnoses.^1-8,17-33 The benefits also extends to QA, education, and research, as diagnoses can not only be rereviewed by specialty or second opinion consultation with ease, but also digital slides can be produced for educational and research purposes.^3-8,35-45 Settings that treat the general population and those focused on the care of veterans or members of the armed forces have reported similar reliability or successful implementation.^35-44,61-63 All in all, the use of telepathology represents an innovation that may transform the practice of pathology tomorrow.

Advances in technology, including ubiquitous access to the internet and the capacity to transfer high-resolution representative images, have facilitated the adoption of telepathology by laboratories worldwide.^1-5 Telepathology includes the use of telecommunication links that enable transmission of digital pathology images for primary diagnosis, quality assurance (QA), education, research, or second opinion diagnoses.³ This improvement has culminated in approvals by the US Food and Drug Administration (FDA) of whole slide imaging (WSI) systems for surgical pathology slides: specifically, the Philips IntelliSite Digital Pathology Solution in 2017 and the Leica Aperio AT2 DX in 2020.^6-8 However, the approvals do not include telecytology due to lack of whole slide multiplanar scanning at different planes of focus or z-stacking capabilities.⁷

Long-term trends in pathology, specifically the slow reduction in the number of practicing pathologists available in the workforce compared with the total served population, along with the social distancing imperatives and disruptions brought about by the COVID-19 pandemic have made telepathology implementation pertinent to continue and improve pathology practice.^8-10

Description and Definitions

The primary modes of telepathology (static image telepathology, robotic telepathology, video microscopy, WSI, and multimodality telepathology) have been defined by the American Telemedicine Association (ATA).² WSI has been particularly suited for telepathology due to the ability to view digital slides in high resolution at various magnifications. These image files can also be viewed and shared with ease with other observers. Also, they take a shorter time to view compared with the use of a robotic microscope.³

Selection, Validation, and Implementation

WSI platforms vary in their characteristics and have several parameters, including but not limited to batch scanning vs continuous or random-access processing, throughput volume capacities, scan speed, cost, manual vs automatic loading of slides, image quality, slide capacity, flexibility for different slide sizes/features, telepathology capabilities once slide scanned, z-stacking, and regulatory approval status.⁸ Selection of the WSI device is dependent on need and cost considerations. For example, use for frozen section requires faster scanning speed and does not generally require a high throughput scanner.

Validation of telepathology by the testing site demonstrates that the new system performs as expected for its intended clinical use before being put into service and that the digital slides produced are acceptable for clinical diagnostic interpretation.¹¹ The College of American Pathologists (CAP) established WSI validation guidelines are part of the published laboratory standard of care.^11-13 An appropriate validation enables the benefits of telepathology while mitigating the risks.

There are 3 major CAP recommendations for validation. First, ≥ 60 cases should be included for each use case being validated with 20 additional cases for relevant ancillary applications not included in the 60 cases. Second, diagnostic concordance (ideally ≥ 95%) should be established between digital and glass slides for the same observer. Third, there should be a 2-week washout period between the viewing of digital and glass slides (Table 2).^12,13

Guidelines from the ATA establish that telepathology systems should be validated for clinical use, including non-WSI platforms.² Published validations of other non-WSI platforms (such as by robotic or multimodality telepathology) have followed the structure proposed in the guidelines by CAP for validating WSI.^14,15

Ensuring that all relevant responsibilities (clinical, facility, technical, training, documentation/archiving, quality management, and operations related) for the use of telepathology are met is another aspect of validation and implementation.² Clinical responsibilities include an agreement between the sending (referring) and receiving (consulting) parties on the information to accompany the digital material.² From ATA clinical guidelines, this includes identification information, provision to the consulting pathologist of all relevant clinical data, provision to retrieve for access any needed and/or relevant diagnostic material, and responsibility by referrer that the correct image/metadata was sent.² Involved parties should be trained to manage the materials being transmitted.²

Facility responsibilities include maintaining the standard of care defined by the facility and regulatory agencies.² The maintenance of accreditation, adherence to licensure requirements, and proper management of privileges to practice telepathology are also important.² Technical responsibilities include ensuring a proper validation that meets the standard of care and covers use cases.^2,11-13

All processes, training, and competencies should be followed and documented per standard facility operating procedures.² ATA recommends that telepathology should result in a formal report for diagnostic consultations, maintain logs of telepathology interactions or disclaimer statements, and have an appropriate retention policy.² The CAP recommends digital images used for primary diagnosis should be kept for 10 years if the original glass slides are not available.¹⁶ Once implemented, telepathology reports must be incorporated into the pathology and laboratory medicine department’s quality management plan for both the technical performance of the telepathology system and diagnostic performance of the pathologists using the system.² Operations responsibilities include ensuring that the telepathology system is maintained according to vendor recommendations and regulatory standards. Appropriate provisions for space and associated needs should be developed in conjunction with the information technology team of the facility to ensure appropriate security, privacy, and regulatory compliance.²

Discrepancies from frozen section telepathology using WSI to the final diagnosis may occur and those specific to WSI could result from slide or image quality, internet connectivity, and lack of training in using the telepathology system.³² Other issues that may lead to discrepancies between the frozen section diagnosis and the final diagnosis may occur with the review of glass slides by light microscopy.³⁴ Appropriate performance of validation, training, implementation, and quality control for telepathology can help in reaping the benefits while mitigating the risks.² In a large study comparing frozen section evaluation by telepathology with light microscopy, the sensitivity and specificity of frozen section were comparable between telepathology and light microscopy with a trend toward greater sensitivity by telepathology (0.92 and 0.99 for telepathology vs 0.90 and 0.99 by light microscopy alone, sensitivity and specificity, respectively).³³

Other applications. Evidence for efficacy in surgical pathology diagnosis led to FDA approval of the Philips IntelliSite Digital Pathology in 2017 and the Leica Aperio AT2 DX in 2020 WSI platforms.^6-8 The use of WSI in surgical pathology has been successfully validated or used in clinical practice at several pathology laboratory settings with documented benefits in the literature for primary and secondary diagnoses, QA, research, and education.^6-8,35-45 Benefits of telepathology include improved ergonomics and access to real-time pathologic services in remote areas or during on-site pathologist absence and expert second opinions. Telepathology also may reduce risk of slide loss during transport, shortened turnaround time, reduced costs of operation through workflow efficiencies, better load balancing, improve virtual collaboration, and digital storage of slides that may be irreplaceable.^3-8,35-45 Telepathology also has been shown to be useful for education, improving access to learning materials and increasing quality instructional materials at a lower cost.⁴⁵ The increased ease of collaboration with remote experts and access to slide material for other pathologists improves QA capabilities.^3-8,35-45 The availability of virtual slides is expected to promote further research in telepathology and pathology due to the increased availability of virtual material to researchers.^1,5,46

Telehematology. Published validations have shown effectiveness for hematopathology specimens, such as the peripheral smear. Telehematology also has demonstrated potential in a laboratory after proper validation and implementation as a laboratory-developed test.^37,47-49

Telemicrobiology and Computer-Assisted Pathologic Diagnosis. Telemicrobiology also has been successfully used for clinical, educational, and QA purposes.⁵⁰ The digitalization of slides involved with telepathology enables further innovation in machine learning for computer-assisted pathologic diagnosis (CAPD), which is already being used clinically for cervical Pap smears.²⁰ An artificial intelligence (AI)–based algorithm analyzes the slides to identify cells of interest, which are presented to the cytopathologist for confirmation.²⁰ However, the expansion of CAPD to include a variety of specimen types or diagnostic situations as well as safely and effectively take initiative in completing an accurate automated diagnosis requires additional development.^20,51,52 One of the key factors for machine learning to develop AI is the provision of a corpus of data.^51,52 Public, open-source data sources have been limited in size while private proprietary sources have highly restricted and expensive access; to address this, there is a current effort to build the world’s largest public open-source digital pathology corpus at Temple University Hospital, which may help enable innovations in the future.⁵²

Long-Term Trends/Applications

The COVID-19 pandemic has been unprecedented not only in its widespread morbidity and mortality, but also for the significant socioeconomic, health, lifestyle, societal, and workspace changes.^53-57 Specifically, the pandemic has introduced not only a need for social distancing and staff quarantines to prevent the spread of infection, but also a reduction in the workforce due to the stresses of COVID-19 (also known as the Great Resignation).⁵⁵ Before the pandemic, there was an existing downtrend in the number of pathologists in the US workforce.^9-10,58,59 From 2007 to 2017, the number of active pathologists in the US declined by 17.5% despite the increasing national population, resulting in not only an absolute decrease in the number of pathologists, but also an increasing population served per pathologist ratio.⁵⁹ Since 2017, this downtrend has continued; given the increasing loss of active pathologists from the workforce and the decreasing training of new pathologists, this decrease shows no signs of reversing even as the impact of the COVID-19 pandemic has begun to wane.^9,10,58-60

The advantages of telepathology in enabling social distancing and reducing travel to remote sites are known.^3-7,17 Given these advantages, some medical centers in the US have previously successfully validated and implemented telepathology operations earlier during the COVID-19 pandemic to ease workflow and ensure continued operations.^56,57 The use of telepathology also helps in balancing workload and continuing pathology operations even in light of the workforce reduction as cases no longer need to be signed out on site with glass slides but instead can be signed out at a remote laboratory. Although the impact of the COVID-19 pandemic on operations is decreasing, the capabilities for social distancing and reducing travel remain important to both improve operations and ensure resiliency in response to similar potential events.^3-7,17,60

Considering the long-term trends, the lessons of the COVID-19 pandemic, and the potential for future pandemics or other disasters, telepathology’s validation and implementation remains a reasonable choice for pathology practices looking to improve. A variety of practices not just in the general population, but also among US Department of Veterans Affairs medical centers (VAMCs) and the US Department of Defense Military Health System treating a veteran population can benefit from telepathology where it has previously been reported to have been reliable or successfully implemented.^61-63 Although the veteran population differs from the general population in several characteristics, such as the severity of disease, coexisting morbidities, and other history, given proper validation and implementation, telepathology’s usefulness extends across different pathology practice settings.^35-43,61-66

Limitations of Telepathology

In telepathology’s current state, there are limitations despite its immense promise.^6,35 These include initial capital costs, the additional training requirement, the additional time necessary to scan slides, technical challenges (ie, laboratory information system integration, color calibration, display artifacts, potential for small particle scanner omissions, and information technology dependence), the potential for slower evaluation per slide compared with optical microscopes, limitations of slide imaging (ie, z-stacking or lack of polarization on digital pathology), and occupational concerns regarding eye strain with increased computer monitor usage (ie, computer vision syndrome).^6,35 In addition, there are few telepathology scanners with FDA approval for WSI.^6-8

The improving technology of telepathology has made these limitations surmountable, including faster slide scanning and increasing digital storage capacity for large WSI files. Due to this improvement in technology, an increasing number of laboratory settings, have adopted telepathology as its advantages have begun to outweigh the limitations.^2-5 Additionally, the proper validation performed before implementing telepathology can help laboratories identify their unique challenges, troubleshoot, and resolve the limitations before use in clinical care.^11-13 Continuing QA during its use and implementation is important to ensure that telepathology performs as expected for clinical purposes despite its limitations.²

Conclusions

Telepathology is a promising technology that may improve pathology practice once properly validated and implemented.^1-8 Though there are barriers to this validation and implementation, particularly the capital costs and training, there are several potential benefits, including increased productivity, cost savings, improvement in the workflow, enhanced access to pathologic consultation, and adaptability of the pathology laboratory in an era of a decreased workforce and social distancing due to the COVID-19 pandemic.^1-8,55-56 This potential applies across the wide spectrum of potential telepathology uses from frozen section, telecytology (including ROSE) to primary and second opinion diagnoses.^1-8,17-33 The benefits also extends to QA, education, and research, as diagnoses can not only be rereviewed by specialty or second opinion consultation with ease, but also digital slides can be produced for educational and research purposes.^3-8,35-45 Settings that treat the general population and those focused on the care of veterans or members of the armed forces have reported similar reliability or successful implementation.^35-44,61-63 All in all, the use of telepathology represents an innovation that may transform the practice of pathology tomorrow.

AT EULAR 2023

MILAN – Safety considerations, particularly regarding the use of Janus kinase (JAK) inhibitors, are of utmost importance in the 2023 update to recommendations for managing psoriatic arthritis (PsA) by the European Alliance of Associations for Rheumatology (EULAR). Additionally, the selection of therapy should now take into account the complete clinical presentation, explicitly considering nonmusculoskeletal manifestations.

Safety considerations with JAK inhibitors

Expanding on the existing six overarching principles from the 2019 recommendations, the PsA EULAR recommendations now introduce a seventh principle: “The choice of treatment should consider safety considerations regarding individual modes of action to optimize the benefit-risk profile.”

This addition was prompted by recent safety data on JAK inhibitors, which revealed serious potential side effects, such as heart attacks, blood clots, cancer, and severe infections, that recently prompted the European Medicines Agency to restrict their use. As indicated by the new principle, safety considerations have been incorporated into several recommendations.

For instance, in the context of peripheral arthritis, JAK inhibitors may now be considered if there is an inadequate response to at least one conventional synthetic disease-modifying antirheumatic drug (csDMARD) such as methotrexate, sulfasalazine, or leflunomide, and at least one biologic DMARD (bDMARD).

Alternatively, JAK inhibitors may be utilized when bDMARDs are not suitable for other reasons. However, EULAR now emphasizes caution whenever JAK inhibitors are mentioned. Specifically, “careful consideration is necessary for patients aged 65 or above, current or past long-time smokers, individuals with a history of atherosclerotic cardiovascular disease or other cardiovascular risk factors, those with other malignancy risk factors, or individuals with a known risk for venous thromboembolism.”
 

Consider nonmusculoskeletal manifestations in treatment decisions

In another significant update, EULAR now recommends that the choice of therapy should also consider nonmusculoskeletal manifestations associated with PsA. “There is a notable shift in perspective here,” Dr. Gossec told this news organization. Clinically relevant skin involvement should prompt the use of IL-17A or IL-17A/F or IL-23 or IL-12/23 inhibitors, while uveitis should be treated with tumor necrosis factor (TNF) inhibitors.

In the case of inflammatory bowel disease, EULAR advises the use of anti-TNF agents, IL-12/23 or IL-23 inhibitors, or a JAK inhibitor. The recommended course of action within each treatment category is not ranked in order of preference, but EULAR emphasizes the importance of following EMA recommendations and considering safety.
 

Systemic glucocorticoids removed

Certain medications have been removed from the recommendations, reflecting the heightened focus on treatment safety. The use of systemic glucocorticoids as adjunctive therapy is no longer recommended. “We always had reservations about their use, and now we have eliminated them. We are aware that they are still utilized, with 30% of patients in Germany, for instance, receiving low doses of glucocorticoids. However, the long-term efficacy/safety balance of glucocorticoids is unfavorable in any disease, particularly in patients with psoriatic arthritis and multiple comorbidities,” Dr. Gossec explained.

NSAIDs and local glucocorticoids are now limited to specific patient populations, namely those affected by oligoarthritis without poor prognostic factors, entheseal disease, or predominant axial disease. Their use should be short-term, generally no longer than 4 weeks. Polyarthritis or oligoarthritis with poor prognostic factors should instead be treated directly with csDMARDs.
 

No specific biologic treatment order recommended for peripheral arthritis

Regarding patients with peripheral arthritis, recent efficacy data have led EULAR to refrain from recommending any specific order of preference for the use of bDMARDs, which encompass TNF inhibitors and drugs targeting the IL-17 and IL-12/23 pathways. “We lack the data to propose an order of preference in patients with peripheral arthritis. Different classes of molecules exhibit efficacy in joint inflammation, generally resulting in a 50% response rate and similar overall effects,” said Dr. Gossec, referencing head-to-head trials between biologics that yielded very comparable results, such as the EXCEED trial or SPIRIT-H2H trial.

The updated recommendations now consider two IL-23p19 inhibitors, guselkumab (Tremfya) and risankizumab (Skyrizi), the JAK inhibitor upadacitinib (Rinvoq), and the very recently EMA-approved bimekizumab (Bimzelx), an IL-17A/F double inhibitor.

The recommendation for patients with mono- or oligoarthritis and poor prognostic factors now aligns with the previous recommendations for polyarthritis: A csDMARD should be initiated promptly, with a preference for methotrexate if significant skin involvement is present. New data suggest that methotrexate may be beneficial for enthesitis, achieving resolution in approximately 30% of patients. When considering treatment options, JAK inhibitors may also be taken into account, with safety considerations in mind.

In cases of clinically relevant axial disease and an inadequate response to NSAIDs, therapy with an IL-17A inhibitor, a TNF inhibitor, an IL-17A/F inhibitor, or a JAK inhibitor may be considered. This approach now aligns with the most recent axial spondyloarthritis recommendation from EULAR and the Assessment of SpondyloArthritis international Society (ASAS).
 

Which disease manifestation to treat first?

During the discussion, chairwoman Uta Kiltz, MD, PhD, a rheumatologist at Rheumatism Center Ruhrgebiet, Herne, Germany, and clinical lecturer at Ruhr University Bochum, inquired about identifying the primary manifestation to guide the course of action.

“Psoriatic arthritis is highly heterogeneous, and determining the predominant manifestation is sometimes challenging,” Dr. Gossec said. “However, we believe that a certain order of preference is necessary when making treatment decisions. Starting with peripheral arthritis, which can lead to structural damage, allows for treatment selection based on that aspect. If peripheral arthritis is not present, attention should be directed towards axial disease, ensuring the presence of actual inflammation rather than solely axial pain, as mechanical origin axial pain can occur due to the patient’s age.”

David Liew, MBBS, PhD, consultant rheumatologist and clinical pharmacologist at Austin Health in Melbourne, commented on the update to this news organization: “We are fortunate to have a wide range of targeted therapy options for psoriatic arthritis, and these guidelines reflect this abundance of choices. They emphasize the importance of selecting therapies based on specific disease manifestations and tailoring care to each patient’s unique type of psoriatic arthritis. It’s worth noting that some changes in these guidelines were influenced by regulatory changes following ORAL Surveillance. In an era of numerous options, we can afford to be selective at times.”

Regarding safety concerns and JAK inhibitors, Dr. Liew added: “It is not surprising to see these guidelines impose certain restrictions on the use of JAK inhibitors, especially in psoriatic arthritis, where other therapies offer distinct advantages. Until high-quality evidence convincingly points away from a class effect, we can expect to see similar provisions in many more guidelines.”

Many of the recommendations’ authors report financial relationships with one or more pharmaceutical companies. These include AbbVie, Amgen, Biogen, Bristol-Myers Squibb, Boehringer Ingelheim, Celgene, Celltrion, Chugai, Galapagos, Gilead, GlaxoSmithKline, Janssen, Leo, Lilly, Medac, Merck, Merck Sharp & Dohme, Novartis, Pfizer, R-Pharma, Regeneron, Roche, Sandoz, Sanofi, Takeda, UCB, and Viatris.

In patients with acute heart failure, a urine sodium-guided diuretic protocol, currently recommended in guidelines from the Heart Failure Association of the European Society of Cardiology (HFA-ESC), led to significant increases in natriuresis and diuresis over 2 days in the prospective ENACT-HF clinical trial.

The guideline protocol was based on a 2019 HFA position paper with expert consensus, but it had not been tested prospectively, Jeroen Dauw, MD, of AZ Sint-Lucas Ghent (Belgium), explained in a presentation at HFA-ESC 2023.

“We had 282 millimoles of sodium excretion after one day, which is an increase of 64%, compared with standard of care,” Dr. Dauw told meeting attendees. “We wanted to power for 15%, so we’re way above it, with a P value of lower than 0.001.”

The effect was consistent across predefined subgroups, he said. “In addition, there’s an even higher benefit in patients with a lower eGFR [estimated glomerular filtration rate] and a higher home dose of loop diuretics, which might signal more diuretic resistance and more benefit of the protocol.”

After 2 days, the investigators saw 52% higher natriuresis and 33% higher diuresis, compared with usual care.

In an interview, Dr. Dauw said, “The protocol is feasible, safe, and very effective. Cardiologists might consider how to implement a similar protocol in their center to improve the care of their acute heart failure patients.”
 

Twice the oral home dose

The investigators conducted a multicenter, open-label, nonrandomized pragmatic trial at 29 centers in 18 countries globally. “We aimed to recruit 500 to detect a 15% difference in natriuresis,” Dr. Dauw said in his presentation, “but because we were a really low-budget trial, we had to stop after 3 years of recruitment.”

Therefore, 401 patients participated, 254 in the SOC arm and 147 in the protocol arm, because of the sequential nature of the study; that is, patients in the SOC arm of the two-phase study were recruited first.

Patients’ mean age was 70 years, 38% were women, and they all had at least one sign of volume overload. They were on a maintenance daily diuretic dose of 40 mg of furosemide for a month or more, and the NT-proBNP was above 1,000.

In phase 1 of the study, all centers treated 10 consecutive patients according to the local standard of care, at the discretion of the physician. In phase 2, the centers again recruited and treated at least 10 consecutive patients, this time according to the standardized diuretic protocol.

In the protocol phase, patients were treated with twice the oral home dose as an IV bolus. “This meant if, for example, you have 40 mg of furosemide at home, then you receive 80 mg as a first bolus,” Dr. Dauw told attendees. A spot urine sample was taken after 2 hours, and the response was evaluated after 6 hours. A urine sodium above 50 millimoles per liter was considered a good response.

On the second day, patients were reevaluated in the morning using urine output as a measure of diuretic response. If it was above 3 L, then the same bolus was repeated again twice daily, with 6-12 hours between administrations.

As noted, after one day, natriuresis was 174 millimoles in the SOC arm versus 282 millimoles in the protocol group – an increase of 64%. The effect was consistent across subgroups, and those with a lower eGFR and a higher home dose of loop diuretics benefited more.

Furthermore, Dr. Dauw said, there was no interaction on the endpoints with SGLT2 inhibitor use at baseline.

After two days, natriuresis was 52% higher in the protocol group and diuresis was 33% higher.

However, there was no significant difference in weight loss and no difference in the congestion score.

“We did expect to see a difference in weight loss between the study groups, as higher natriuresis and diuresis would normally be associated with higher weight loss in the protocol group,” Dr. Dauw told this news organization. “However, looking back at the study design, weight was collected from the electronic health records and not rigorously collected by study nurses. Previous studies have shown discrepancies between fluid loss and weight loss, so this is an ‘explainable’ finding.”

Participants also had a relatively high congestion score at baseline, with edema above the knee and also some pleural effusion, he told meeting attendees. Therefore, it might take more time to see a change in congestion score in those patients.

The protocol also led to a shorter length of stay – one day less in the hospital – and was very safe on renal endpoints, Dr. Dauw concluded.

A session chair asked why only patients already on diuretics were included in the study, noting that in his clinic, about half of the admissions are de novo.

Dr. Dauw said that patients already taking diuretics chronically would benefit most from the protocol. “If patients are diuretic-naive, they probably will respond well to whatever you do; if you just give a higher dose, they will respond well,” he said. “We expected that the largest benefit would be in patients already taking diuretics because they have a higher chance of not responding well.”

“There also was a big difference in the starting dose,” he added. “In the SOC arm, the baseline dose was about 60 mg, whereas we gave 120 mg, and we could already see a high difference in the effect. So, in those patients, I think the gain is bigger if you follow the protocol.”
 

More data coming

Looking ahead, “we only showed efficacy in the first 2 days of treatment and a shorter length of stay, probably reflecting a faster decongestion, but we don’t know for sure,” Dr. Dauw told this news organization.

“It would be important to have a study where the protocol is followed until full decongestion is reached,” he said. “That way, we can directly prove that decongestion is better and/or faster with the protocol.”

“A good decongestive strategy is one that is fast, safe and effective in decreasing signs and symptoms that patients suffer from,” he added. “We believe our protocol can achieve that, but our study is only one piece of the puzzle.”

More data on natriuresis-guided decongestion is coming this year, he said, with the PUSH-AHF study from Groningen, the European DECONGEST study, and the U.S. ESCALATE study.

The study had no funding. Dr. Dauw declared no relevant financial relationships.

In patients with acute heart failure, a urine sodium-guided diuretic protocol, currently recommended in guidelines from the Heart Failure Association of the European Society of Cardiology (HFA-ESC), led to significant increases in natriuresis and diuresis over 2 days in the prospective ENACT-HF clinical trial.

The guideline protocol was based on a 2019 HFA position paper with expert consensus, but it had not been tested prospectively, Jeroen Dauw, MD, of AZ Sint-Lucas Ghent (Belgium), explained in a presentation at HFA-ESC 2023.

“We had 282 millimoles of sodium excretion after one day, which is an increase of 64%, compared with standard of care,” Dr. Dauw told meeting attendees. “We wanted to power for 15%, so we’re way above it, with a P value of lower than 0.001.”

The effect was consistent across predefined subgroups, he said. “In addition, there’s an even higher benefit in patients with a lower eGFR [estimated glomerular filtration rate] and a higher home dose of loop diuretics, which might signal more diuretic resistance and more benefit of the protocol.”

After 2 days, the investigators saw 52% higher natriuresis and 33% higher diuresis, compared with usual care.

In an interview, Dr. Dauw said, “The protocol is feasible, safe, and very effective. Cardiologists might consider how to implement a similar protocol in their center to improve the care of their acute heart failure patients.”
 

Twice the oral home dose

The investigators conducted a multicenter, open-label, nonrandomized pragmatic trial at 29 centers in 18 countries globally. “We aimed to recruit 500 to detect a 15% difference in natriuresis,” Dr. Dauw said in his presentation, “but because we were a really low-budget trial, we had to stop after 3 years of recruitment.”

Therefore, 401 patients participated, 254 in the SOC arm and 147 in the protocol arm, because of the sequential nature of the study; that is, patients in the SOC arm of the two-phase study were recruited first.

Patients’ mean age was 70 years, 38% were women, and they all had at least one sign of volume overload. They were on a maintenance daily diuretic dose of 40 mg of furosemide for a month or more, and the NT-proBNP was above 1,000.

In phase 1 of the study, all centers treated 10 consecutive patients according to the local standard of care, at the discretion of the physician. In phase 2, the centers again recruited and treated at least 10 consecutive patients, this time according to the standardized diuretic protocol.

In the protocol phase, patients were treated with twice the oral home dose as an IV bolus. “This meant if, for example, you have 40 mg of furosemide at home, then you receive 80 mg as a first bolus,” Dr. Dauw told attendees. A spot urine sample was taken after 2 hours, and the response was evaluated after 6 hours. A urine sodium above 50 millimoles per liter was considered a good response.

On the second day, patients were reevaluated in the morning using urine output as a measure of diuretic response. If it was above 3 L, then the same bolus was repeated again twice daily, with 6-12 hours between administrations.

As noted, after one day, natriuresis was 174 millimoles in the SOC arm versus 282 millimoles in the protocol group – an increase of 64%. The effect was consistent across subgroups, and those with a lower eGFR and a higher home dose of loop diuretics benefited more.

Furthermore, Dr. Dauw said, there was no interaction on the endpoints with SGLT2 inhibitor use at baseline.

After two days, natriuresis was 52% higher in the protocol group and diuresis was 33% higher.

However, there was no significant difference in weight loss and no difference in the congestion score.

“We did expect to see a difference in weight loss between the study groups, as higher natriuresis and diuresis would normally be associated with higher weight loss in the protocol group,” Dr. Dauw told this news organization. “However, looking back at the study design, weight was collected from the electronic health records and not rigorously collected by study nurses.

CHARLESTON, S.C. – Melanie Gray Miller, a 30-year-old physician, wiped away tears as she described the isolation she felt after losing a beloved patient.
 

“It was at the end of a night shift, when it seems like bad things always happen,” said Dr. Miller, who is training to become a pediatrician.

The infant had been sick for months in the Medical University of South Carolina’s pediatric intensive care unit and the possibility that he might not improve was obvious, Dr. Miller recalled during an April meeting with physicians and hospital administrators. But the suddenness of his death still caught her off guard.

“I have family and friends that I talk to about things,” she said. “But no one truly understands.”

Doctors don’t typically take time to grieve at work. But during that recent meeting, Dr. Miller and her colleagues opened up about the insomnia, emotional exhaustion, trauma, and burnout they experienced from their time in the pediatric ICU.

“This is not a normal place,” Grant Goodrich, the hospital system’s director of ethics, said to the group, acknowledging an occupational hazard the industry often downplays. “Most people don’t see kids die.”

The recurring conversation, scheduled for early-career doctors coming off month-long pediatric ICU rotations, is one way the hospital helps staffers cope with stress, according to Alyssa Rheingold, a licensed clinical psychologist who leads its resiliency program.

“Often the focus is to teach somebody how to do yoga and take a bath,” she said. “That’s not at all what well-being is about.”

Dr. Miller says working in the hospital’s pediatric intensive care unit can be tough. “In medicine, we’re just expected to be resilient 24/7,” she says. The trauma and stress from patients dying can be particularly hard to process.

Burnout in the health care industry is a widespread problem that long predates the COVID-19 pandemic, though the chaos introduced by the coronavirus’s spread made things worse, physicians and psychologists said. Health systems across the country are trying to boost morale and keep clinicians from quitting or retiring early, but the stakes are higher than workforce shortages.

Rates of physician suicide, partly fueled by burnout, have been a concern for decades. And while burnout occurs across medical specialties, some studies have shown that primary care doctors, such as pediatricians and family physicians, may run a higher risk.

“Why go into primary care when you can make twice the money doing something with half the stress?” said Daniel Crummett, a retired primary care doctor who lives in North Carolina. “I don’t know why anyone would go into primary care.”

Doctors say they are fed up with demands imposed by hospital administrators and health insurance companies, and they’re concerned about the notoriously grueling shifts assigned to medical residents during the early years of their careers. A long-standing stigma keeps physicians from prioritizing their own mental health, while their jobs require them to routinely grapple with death, grief, and trauma. The culture of medicine encourages them to simply bear it.

“Resiliency is a cringe word for me,” Dr. Miller said. “In medicine, we’re just expected to be resilient 24/7. I don’t love that culture.”

And though the pipeline of physicians entering the profession is strong, the ranks of doctors in the United States aren’t growing fast enough to meet future demand, according to the American Medical Association. That’s why burnout exacerbates workforce shortages and, if it continues, may limit the ability of some patients to access even basic care. A 2021 report published by the Association of American Medical Colleges projects the United States will be short as many as 48,000 primary care physicians by 2034, a higher number than any other single medical specialty.

A survey published last year by The Physicians Foundation, a nonprofit focused on improving health care, found more than half of the 1,501 responding doctors didn›t have positive feelings about the current or future state of the medical profession. More than 20% said they wanted to retire within a year.

Similarly, in a 2022 AMA survey of 11,000 doctors and other medical professionals, more than half reported feeling burned out and indicated they were experiencing a great deal of stress.

Those numbers appear to be even higher in primary care. Even before the pandemic, 70% of primary care providers and 89% of primary care residents reported feelings of burnout.

“Everyone in health care feels overworked,” said Gregg Coodley, a primary care physician in Portland, Ore., and author of the book “Patients in Peril: The Demise of Primary Care in America”

“I’m not saying there aren’t issues for other specialists, too, but in primary care, it’s the worst problem,” he said.

The high level of student debt most medical school graduates carry, combined with salaries more than four times as high as the average, deter many physicians from quitting medicine midcareer. Even primary care doctors, whose salaries are among the lowest of all medical specialties, are paid significantly more than the average American worker. That's why, instead of leaving the profession in their 30s or 40s, doctors often stay in their jobs but retire early.

“We go into medicine to help people, to take care of people, to do good in the world,” said Dr. Crummett, who retired from the Duke University hospital system in 2020 when he turned 65.

Dr. Crummett said he would have enjoyed working until he was 70, if not for the bureaucratic burdens of practicing medicine, including needing to get prior authorization from insurance companies before providing care, navigating cumbersome electronic health record platforms, and logging hours of administrative work outside the exam room.

“I enjoyed seeing patients. I really enjoyed my coworkers,” he said. “The administration was certainly a major factor in burnout.”

Jean Antonucci, a primary care doctor in rural Maine who retired from full-time work at 66, said she, too, would have kept working if not for the hassle of dealing with hospital administrators and insurance companies.

Once, Dr. Antonucci said, she had to call an insurance company – by landline and cellphone simultaneously, with one phone on each ear – to get prior authorization to conduct a CT scan, while her patient in need of an appendectomy waited in pain. The hospital wouldn’t conduct the scan without insurance approval.

“It was just infuriating,” said Dr. Antonucci, who now practices medicine only 1 day a week. “I could have kept working. I just got tired.”

Providers’ collective exhaustion is a crisis kept hidden by design, said Whitney Marvin, a pediatrician who works in the pediatric ICU at the Medical University of South Carolina. She said hospital culture implicitly teaches doctors to tamp down their emotions and to “keep moving.”

“I’m not supposed to be weak, and I’m not supposed to cry, and I’m not supposed to have all these emotions, because then maybe I’m not good enough at my job,” said Dr. Marvin, describing the way doctors have historically thought about their mental health.

This mentality prevents many doctors from seeking the help they need, which can lead to burnout – and much worse. An estimated 300 physicians die by suicide every year, according to the American Foundation for Suicide Prevention. The problem is particularly pronounced among female physicians, who die by suicide at a significantly higher rate than women in other professions.

A March report from this news organization found, of more than 9,000 doctors surveyed, 9% of male physicians and 11% of female physicians said they have had suicidal thoughts. But the problem isn’t new, the report noted. Elevated rates of suicide among physicians have been documented for 150 years.

“Ironically, it’s happening to a group of people who should have the easiest access to mental health care,” said Gary Price, a Connecticut surgeon and president of The Physicians Foundation.

But the reluctance to seek help isn’t unfounded, said Corey Feist, president of the Dr. Lorna Breen Heroes’ Foundation .

“There’s something known in residency as the ‘silent curriculum,’ ” Mr. Feist said in describing an often-unspoken understanding among doctors that seeking mental health treatment could jeopardize their livelihood.

Mr. Feist’s sister-in-law, emergency room physician Lorna Breen, died by suicide during the early months of the pandemic. Dr. Breen sought inpatient treatment for mental health once, Mr. Feist said, but feared that her medical license could be revoked for doing so.

The foundation works to change laws across the country to prohibit medical boards and hospitals from asking doctors invasive mental health questions on employment or license applications.

“These people need to be taken care of by us, because really, no one’s looking out for them,” Mr. Feist said.

In Charleston, psychologists are made available to physicians during group meetings like the one Dr. Miller attended, as part of the resiliency program.

But fixing the burnout problem also requires a cultural change, especially among older physicians.

“They had it worse and we know that. But it’s still not good,” Dr. Miller said. “Until that changes, we’re just going to continue burning out physicians within the first 3 years of their career.”

Doctors don’t typically take time to grieve at work. But during that recent meeting, Dr. Miller and her colleagues opened up about the insomnia, emotional exhaustion, trauma, and burnout they experienced from their time in the pediatric ICU.

“This is not a normal place,” Grant Goodrich, the hospital system’s director of ethics, said to the group, acknowledging an occupational hazard the industry often downplays. “Most people don’t see kids die.”

The recurring conversation, scheduled for early-career doctors coming off month-long pediatric ICU rotations, is one way the hospital helps staffers cope with stress, according to Alyssa Rheingold, a licensed clinical psychologist who leads its resiliency program.

“Often the focus is to teach somebody how to do yoga and take a bath,” she said. “That’s not at all what well-being is about.”

Dr. Miller says working in the hospital’s pediatric intensive care unit can be tough. “In medicine, we’re just expected to be resilient 24/7,” she says. The trauma and stress from patients dying can be particularly hard to process.

Burnout in the health care industry is a widespread problem that long predates the COVID-19 pandemic, though the chaos introduced by the coronavirus’s spread made things worse, physicians and psychologists said. Health systems across the country are trying to boost morale and keep clinicians from quitting or retiring early, but the stakes are higher than workforce shortages.

Rates of physician suicide, partly fueled by burnout, have been a concern for decades. And while burnout occurs across medical specialties, some studies have shown that primary care doctors, such as pediatricians and family physicians, may run a higher risk.

“Why go into primary care when you can make twice the money doing something with half the stress?” said Daniel Crummett, a retired primary care doctor who lives in North Carolina. “I don’t know why anyone would go into primary care.”

Doctors say they are fed up with demands imposed by hospital administrators and health insurance companies, and they’re concerned about the notoriously grueling shifts assigned to medical residents during the early years of their careers. A long-standing stigma keeps physicians from prioritizing their own mental health, while their jobs require them to routinely grapple with death, grief, and trauma. The culture of medicine encourages them to simply bear it.

“Resiliency is a cringe word for me,” Dr. Miller said. “In medicine, we’re just expected to be resilient 24/7. I don’t love that culture.”

And though the pipeline of physicians entering the profession is strong, the ranks of doctors in the United States aren’t growing fast enough to meet future demand, according to the American Medical Association. That’s why burnout exacerbates workforce shortages and, if it continues, may limit the ability of some patients to access even basic care. A 2021 report published by the Association of American Medical Colleges projects the United States will be short as many as 48,000 primary care physicians by 2034, a higher number than any other single medical specialty.

A survey published last year by The Physicians Foundation, a nonprofit focused on improving health care, found more than half of the 1,501 responding doctors didn›t have positive feelings about the current or future state of the medical profession. More than 20% said they wanted to retire within a year.

Similarly, in a 2022 AMA survey of 11,000 doctors and other medical professionals, more than half reported feeling burned out and indicated they were experiencing a great deal of stress.

Those numbers appear to be even higher in primary care. Even before the pandemic, 70% of primary care providers and 89% of primary care residents reported feelings of burnout.

“Everyone in health care feels overworked,” said Gregg Coodley, a primary care physician in Portland, Ore., and author of the book “Patients in Peril: The Demise of Primary Care in America”

“I’m not saying there aren’t issues for other specialists, too, but in primary care, it’s the worst problem,” he said.

The high level of student debt most medical school graduates carry, combined with salaries more than four times as high as the average, deter many physicians from quitting medicine midcareer. Even primary care doctors, whose salaries are among the lowest of all medical specialties, are paid significantly more than the average American worker. That's why, instead of leaving the profession in their 30s or 40s, doctors often stay in their jobs but retire early.

“We go into medicine to help people, to take care of people, to do good in the world,” said Dr. Crummett, who retired from the Duke University hospital system in 2020 when he turned 65.

Dr. Crummett said he would have enjoyed working until he was 70, if not for the bureaucratic burdens of practicing medicine, including needing to get prior authorization from insurance companies before providing care, navigating cumbersome electronic health record platforms, and logging hours of administrative work outside the exam room.

“I enjoyed seeing patients. I really enjoyed my coworkers,” he said. “The administration was certainly a major factor in burnout.”

Jean Antonucci, a primary care doctor in rural Maine who retired from full-time work at 66, said she, too, would have kept working if not for the hassle of dealing with hospital administrators and insurance companies.

Once, Dr. Antonucci said, she had to call an insurance company – by landline and cellphone simultaneously, with one phone on each ear – to get prior authorization to conduct a CT scan, while her patient in need of an appendectomy waited in pain. The hospital wouldn’t conduct the scan without insurance approval.

“It was just infuriating,” said Dr. Antonucci, who now practices medicine only 1 day a week. “I could have kept working. I just got tired.”

Providers’ collective exhaustion is a crisis kept hidden by design, said Whitney Marvin, a pediatrician who works in the pediatric ICU at the Medical University of South Carolina. She said hospital culture implicitly teaches doctors to tamp down their emotions and to “keep moving.”

“I’m not supposed to be weak, and I’m not supposed to cry, and I’m not supposed to have all these emotions, because then maybe I’m not good enough at my job,” said Dr. Marvin, describing the way doctors have historically thought about their mental health.

This mentality prevents many doctors from seeking the help they need, which can lead to burnout – and much worse. An estimated 300 physicians die by suicide every year, according to the American Foundation for Suicide Prevention. The problem is particularly pronounced among female physicians, who die by suicide at a significantly higher rate than women in other professions.

A March report from this news organization found, of more than 9,000 doctors surveyed, 9% of male physicians and 11% of female physicians said they have had suicidal thoughts. But the problem isn’t new, the report noted. Elevated rates of suicide among physicians have been documented for 150 years.

“Ironically, it’s happening to a group of people who should have the easiest access to mental health care,” said Gary Price, a Connecticut surgeon and president of The Physicians Foundation.

But the reluctance to seek help isn’t unfounded, said Corey Feist, president of the Dr. Lorna Breen Heroes’ Foundation .

“There’s something known in residency as the ‘silent curriculum,’ ” Mr. Feist said in describing an often-unspoken understanding among doctors that seeking mental health treatment could jeopardize their livelihood.

Mr. Feist’s sister-in-law, emergency room physician Lorna Breen, died by suicide during the early months of the pandemic. Dr. Breen sought inpatient treatment for mental health once, Mr. Feist said, but feared that her medical license could be revoked for doing so.

The foundation works to change laws across the country to prohibit medical boards and hospitals from asking doctors invasive mental health questions on employment or license applications.

“These people need to be taken care of by us, because really, no one’s looking out for them,” Mr. Feist said.

In Charleston, psychologists are made available to physicians during group meetings like the one Dr. Miller attended, as part of the resiliency program.

But fixing the burnout problem also requires a cultural change, especially among older physicians.

“They had it worse and we know that. But it’s still not good,” Dr. Miller said. “Until that changes, we’re just going to continue burning out physicians within the first 3 years of their career.”

A low-carbohydrate breakfast was better than a control (low-fat) breakfast to decrease glycemic variability throughout the day in type 2 diabetes, in new research.

These findings from a 3-month randomized study in 121 patients in Canada and Australia were published online recently in the American Journal of Clinical Nutrition.

The researchers aimed to determine whether a low-carbohydrate, high-fat breakfast (focused around eggs), compared with a standard, low-fat control breakfast (designed to have no/minimal eggs), would improve blood glucose control in individuals with type 2 diabetes.

“We’ve determined that if the first meal of the day is low-carb and higher in protein and fat we can limit hyperglycemic swings,” lead author Barbara Oliveira, PhD, School of Health and Exercise Sciences, University of British Columbia, Kelowna, said in a press release from the university.

“Having fewer carbs for breakfast not only aligns better with how people with [type 2 diabetes] handle glucose throughout the day,” she noted, “but it also has incredible potential for people with [type 2 diabetes] who struggle with their glucose levels in the morning.”

“By making a small adjustment to the carb content of a single meal rather than the entire diet,” Dr. Oliveira added, “we have the potential to increase adherence significantly while still obtaining significant benefits.”

The researchers conclude that “this trial provides evidence that advice to consume a low-carbohydrate breakfast could be a simple, feasible, and effective approach to manage postprandial hyperglycemia and lower glycemic variability in people living with type 2 diabetes.”
 

Could breakfast tweak improve glucose control?

People with type 2 diabetes have higher levels of insulin resistance and greater glucose intolerance in the morning, the researchers write.

And consuming a low-fat, high-carbohydrate meal in line with most dietary guidelines appears to incur the highest hyperglycemia spike and leads to higher glycemic variability.

They speculated that eating a low-carb breakfast, compared with a low-fat breakfast, might be an easy way to mitigate this.

They recruited participants from online ads in three provinces in Canada and four states in Australia, and they conducted the study from a site in British Columbia and one in Wollongong, Australia.

The participants were aged 20-79 years and diagnosed with type 2 diabetes. They also had a current hemoglobin A1c < 8.5% and no allergies to eggs, and they were able to follow remote, online guidance.

After screening, the participants had a phone or video conference call with a member of the research team who explained the study.

The researchers randomly assigned 75 participants in Canada and 46 participants in Australia 1:1 to the low-carbohydrate intervention or the control intervention.

The participants had a mean age of 64 and 53% were women. They had a mean weight of 93 kg (204 lb), body mass index of 32 kg/m², and A1c of 7.0%.

Registered dietitians in Canada and Australia each designed 8-10 recipes/menus for low-carb breakfasts and an equal number of recipes/menus for control (low-fat) breakfasts that were specific for those countries.

Each recipe contains about 450 kcal, and they are available in Supplemental Appendix 1A and 1B, with the article.

Each low-carbohydrate breakfast contains about 25 g protein, 8 g carbohydrates, and 37 g fat. For example, one breakfast is a three-egg omelet with spinach.

Each control (low-fat) recipe contains about 20 g protein, 56 g carbohydrates, and 15 g fat. For example, one breakfast is a small blueberry muffin and a small plain Greek yogurt.

The participants were advised to select one of these breakfasts every day and follow it exactly (they were also required to upload a photograph of their breakfast every morning). They were not given any guidance or calorie restriction for the other meals of the day.

The participants also filled in 3-day food records and answered a questionnaire about exercise, hunger, and satiety, at the beginning, middle, and end of the intervention.

They provided self-reported height, weight, and waist circumference, and they were given requisitions for blood tests for A1c to be done at a local laboratory, at the beginning and end of the intervention.

The participants also wore a continuous glucose monitor (CGM) during the first and last 14 days of the intervention.
 

Intervention improved CGM measures

There was no significant difference in the primary outcome, change in A1c, at the end of 12 weeks, in the two groups. The mean A1c decreased by 0.3% in the intervention group vs 0.1% in the control group (P = .06).

Similarly, in secondary outcomes, weight and BMI each decreased about 1% and waist circumference decreased by about 2.5 cm in each group at 12 weeks (no significant difference). There were also no significant differences in hunger, satiety, or physical activity between the two groups.

However, the 24-hour CGM data showed that mean and maximum glucose, glycemic variability, and time above range were all significantly lower in participants in the low-carbohydrate breakfast intervention group vs. those in the control group (all P < .05).

Time in range was significantly higher among participants in the intervention group (P < .05).

In addition, the 2-hour postprandial CGM data showed that mean glucose and maximum glucose after breakfast were lower in participants in the low-carbohydrate breakfast group than in the control group.

Little, PhD, School of Health and Exercise Sciences, University of British Columbia, from the Egg Nutrition Center, United States, and Egg Farmers of Canada.
