The rapid transition to and reliance on telehealth to manage patients with heart failure during the COVID-19 pandemic does not appear to impact clinical outcomes, according to real-world data.

HF outpatients managed with telehealth visits did not show a significantly higher adjusted risk for subsequent ED visits, hospital admissions, intensive care use, or death at 30 and 90 days, the investigators reported in JACC: Heart Failure.

“Telehealth is safe and effective in probably some of our highest-risk patients who traditionally have needed hands-on, in-person assessment and evaluation – those patients who have heart failure – so we shouldn’t be afraid to use it all the time, not when needed as a minimum,” senior author Brett W. Sperry, MD, said in an interview.

Heart failure is a perfect case example to examine telehealth because the chronic condition not only requires continual assessment and medication adjustments, but HF patients are also particularly vulnerable to complications related to COVID-19 infection, he noted. A small, single-center report on telehealth early in Italy’s outbreak showed fewer HF hospitalizations and similar mortality, compared with in-person visits in 2019 but, overall, few data exist.

The current analysis took a wider sweep, comparing HF patients seen from March 15 to June 15, 2020 with those seen during the same time period in 2018 and 2019 at 16 cardiology clinics in Saint Luke’s Health System, which serves the Kansas City metro area and surrounding suburbs in Missouri and Kansas.

Among 8,263 unique patients and 15,421 visits identified, telehealth was not used in 2018 or 2019 but accounted for 88.5% of visits during the study period in 2020, 70% of which were by telephone and 30% of which were by video.

“We had zero telehealth before March 2020 and basically built an entire telehealth apparatus in a week or 2,” explained Dr. Sperry. “Initially it was a lot of telephone visits while we were getting the video stuff figured out, which is reflected in the paper, and then went to mostly video visits.”

Despite the pandemic, however, more outpatients were seen in 2020 than in 2018 and 2019 (4,063 vs. 3675 and 3,619 patients, respectively). This likely reflects the shift of personnel and resources from hospital duties to outpatient virtual visits, which were strongly recommended by the Heart Failure Society of America and other professional societies to manage patients during the pandemic, he said.

Unadjusted analyses demonstrated fewer ED visits and hospital admissions and more ICU admissions and all-cause mortality in 2020 than in previous years.

A propensity-matched analysis involving 4541 pairs of patients, however, showed admissions to the ED or hospital were lower after the telehealth visits than after in-person visits at 30 days (6.8% vs 10.4%; P < .001) and 90 days (17.9% vs. 23.3%; P < .001).

Among hospitalized patients, there was no difference between telehealth and in-patient visits in ICU admissions at 30 or 90 days. Mortality was also similar at 30 days (0.8% vs. 0.7%; P = .465) and 90 days (2.9% vs. 2.4%; P = .133).

Dr. Sperry said the pendulum has swung since 2020 and that the team is back to seeing most people in person, with about 15% of his clinic visits that day done via video. Standardized quality of life assessments prior to outpatient visits can help triage patients to telehealth in-patient visits, but in-person visits will still be needed for cases with greater acuity, older patients, and those with limited or no access to quality telephone videos or the internet.

“It isn’t for everyone,” Dr. Sperry said. “You’re going to need some kind of hybrid model with both in-person and video visits available and be able to offer both for patients and be able to titrate that as the pandemic changes in the future.”

Ankit Bhatia, MD, an advanced HF cardiologist at Christ Hospital in Cincinnati, who was not part of the study, said in an interview the use of telehealth in 85% of patients may be higher than the norm at most centers but that the study provides much-needed data.

“I’m really appreciative of a study like this because we were all in such a rush last year to get patients seen that very few people thought how could we design a study to really ensure we’re treating our patients within an equipoise with prior practices,” he said.

“The fact that they were able to do that [85%] and demonstrate in a propensity-matched analysis that outcomes were similar really just shows that telehealth is a strategy that we can use well in patients with heart failure to extend our ability to take care of them,” said Dr. Bhatia, a member of the American College of Cardiology Health Care Innovation Council.

Even beyond the pandemic, he said, the trend in health care is for patients to want health care delivered closer to home and for health care systems to become more patient centric. “This accelerated that but what I think this study showed me was that it’s okay to have this be part of my care model and I’m not sacrificing on my patient care if I choose to intersperse telehealth with inpatient visits.”

Besides the inherent limitations of retrospective studies, the authors noted that diagnoses in the study were based on ICD-10 codes and that subsequent ED visits or hospitalizations outside the single system may have been underreported. A further limitation is that they could not identify the cause of death or reasons for hospital encounters.

“Further data are needed to confirm the relative safety of a telehealth strategy in the HF population over a more sustained period of time, although we hypothesize that greater risks would be observed early after telehealth visits, where patients’ acuity might be misjudged,” they wrote.

The Food and Drug Administration issued a warning today about the use of needle-free devices for injecting dermal fillers – which are promoted to the public on social media and have resulted in serious and permanent injuries.

Specifically, the warning advises consumers and health care professionals “not to use needle-free devices such as hyaluron pens for injection of hyaluronic acid (HA) or other lip and facial fillers, collectively and commonly referred to as dermal fillers or fillers.”

According to the statement, the agency “is aware of serious injuries and in some cases, permanent harm to the skin, lips, or eyes with the use of needle-free devices for injection of fillers.”

Needle-free devices and lip and facial fillers for use with these devices are being sold directly to consumers online, and are promoted on social media “to increase lip volume, improve the appearance of wrinkles, change the shape of the nose, and other similar procedures,” according to the FDA warning.

The FDA points out that FDA-approved dermal fillers are for prescription use only, and should be administered only by licensed health care professionals using a syringe with a needle or cannula, and advises consumers not to buy or use lip or facial fillers sold directly to the public.

These products may be contaminated with infectious agents or chemicals. Moreover, “needle-free injection devices for aesthetic purposes do not provide enough control over where the injected product is placed,” the statement adds. In addition to infections, other risks include bleeding and bruising, formation of lumps, allergic reactions, blockage of a blood vessel (which can result in necrosis, blindness, or stroke), and transmission of diseases from sharing devices.

The FDA’s recommendations for health care providers include not using any aesthetic fillers with a needle-free device, and not using approved dermal fillers in such devices.

The American Society for Dermatologic Surgery Association (ASDSA) commended the FDA on the safety communication in a statement issued on October 11. In February, the ASDSA issued an alert about children using hyaluron pens to self-inject hyaluronic filler into the epidermal and upper dermal skin layers. 

“I am pleased that the FDA has taken notice of this disturbing new trend, especially that of children using these devices on social media,” ASDSA president Mathew Avram, MD, JD, director of the Dermatology Laser and Cosmetic Center, at Massachusetts General Hospital, Boston, said in the statement. “The complexity of facial anatomy requires in-depth knowledge and expertise, and patients should always have medical procedures done by a physician who also has knowledge of adverse events,” he added, urging consumers to see a board-certified dermatologist before undergoing any cosmetic procedure.

In response to a query, an FDA spokesperson did not have an estimate of the number of reports of these adverse events.

People who have problems or are concerned about having had a filler injected with a needle-free device should contact a licensed health care provider. Consumers and health care professionals should report adverse events related to injection of fillers with a needle-free device to the FDA’s MedWatch program. In addition to MedWatch, adverse events can also be reported to the Cutaneous Procedures Adverse Events Reporting (CAPER) Registry, established earlier this year by the ASDSA with the department of dermatology at Northwestern University, Chicago.

A new position statement from the Royal Australian and New Zealand College of Psychiatrists (RANZCP) stresses the importance of a mental health evaluation for people with gender dysphoria – in particular for children and adolescents – before any firm decisions are made on whether to prescribe hormonal treatments to transition, or perform surgeries, often referred to as “gender-affirming care.”

“There is a paucity of quality evidence on the outcomes of those presenting with gender dysphoria. In particular, there is a need for better evidence in relation to outcomes for children and young people,” the guidance states.

Because gender dysphoria “is associated with significant distress ... each case should be assessed by a mental health professional, which will frequently be a psychiatrist, with the person at the center of care. It is important the psychological state and context in which gender dysphoria has arisen is explored to assess the most appropriate treatment,” it adds.

The move by the psychiatry body represents a big shift in the landscape regarding recommendations for the treatment of gender dysphoria in Australia and New Zealand.

Asked to explain the new RANZCP position, Philip Morris, MBBS, FRANZCP, said: “The College acknowledged the complexity of the issues and the legitimacy of different approaches.”

Exploration of a patient’s reasons for identifying as transgender is essential, he said in an interview, especially when it comes to young people.

“There may be other reasons for doing it, and we need to look for those, identify them and treat them. This needs to be done before initiating hormones and changing the whole physical nature of the child,” he said.

“A cautious psychotherapy-first approach makes sense. If we can do that with adolescents, then we will take a big step in the right direction,” stressed Dr. Morris, who is president of the National Association of Practising Psychiatrists in Australia.
 

Keira Bell case and Scandinavian stance lead to more open discussion

The rapid rise in gender dysphoria among adolescents in the Western world, referred to as “rapid-onset” or “late-onset” gender dysphoria, has seen a huge increase in the number of natal girls presenting and created frenzied debate that has intensified worldwide in the last 12 months about how to best treat youth with gender dysphoria.

Concerns have arisen that some transgender identification is due to social contagion, and there is a growing number of “detransitioners” – people who identified as transgender, transitioned to the opposite gender, but then regretted their decision, changed their minds, and “detransitioned” back to their birth sex. If they have had hormone therapy, and in some cases surgery, they are left with irreversible changes to their bodies.

As a result, Scandinavian countries, most notably Finland, once eager advocates of the gender-affirmative approach, have pulled back and issued new treatment guidelines in 2020 stating that psychotherapy, rather than gender reassignment, should be the first line of treatment for gender-dysphoric youth.

This, along with a landmark High Court decision in the U.K. regarding the use of puberty-blocking drugs for children with gender dysphoria, brought by detransitioner Keira Bell, which was recently overturned by the Appeal Court, but which Ms. Bell now says she will take to the Supreme Court, has led to a considerable shift in the conversation around treating transgender adolescents with hormonal therapy, says Dr. Morris.

“This [has moved from] ... a topic that could previously not be talked about freely to one that we can discuss more openly now. This is a big improvement. Previously, everyone thought it was all settled, but it’s not, certainly not from a medical angle,” he states.
 

At odds with prior Australian recommendations

The RANZCP had previously endorsed the standard guidelines of the Royal Children’s Hospital (RCH) Melbourne, followed by most gender-identity services in Australia and similar guidance from New Zealand, which both recommend gender-affirming care.

“Increasing evidence demonstrates that with supportive, gender-affirming care during childhood and adolescence, harms can be ameliorated and mental health and well-being outcomes can be significantly improved,” state the RCH guidelines.

But in 2019, RANZCP removed its endorsement of the RCH guidelines and started a consultation, which resulted in the new position statement.

However, Ken Pang, MD, of the Murdoch Children’s Research Institute in Melbourne and an author of the RCH guidelines, says the key recommendations of the new RANZCP position statement are consistent with their own guidelines.

The former note “the need for a skilled mental health clinician in providing comprehensive exploration of a child or adolescent’s biopsychosocial context,” Dr. Pang says.

However, it’s difficult not to see the contrast in stance when the new RANZCP statement maintains: “Research on gender dysphoria is still emerging. There are polarized views and mixed evidence regarding treatment options for people presenting with gender identity concerns, especially children and young people.”

Dr. Pang says the RCH guidelines do, however, recognize the need for further research in the field.

“I look forward to being able to incorporate such research, including from our own Trans20 study, into future revisions of our guidelines,” he told this news organization.
 

Watch your backs with affirmative therapy: Will there be a compromise?

Dr. Morris says there will obviously be cases where “the child might transition with a medical intervention, but that wouldn’t be the first step.”

And yet, he adds, “There are those who push the pro-trans view that everyone should be allowed to transition, and the doctors are only technicians that provide hormones with no questions asked.” 

But from a doctor’s perspective, clinicians will still be held responsible in medical and legal terms for the treatments given, he stressed.

“I don’t think they will ever not be accountable for that. They will always need to determine in their own mind whether their actions have positive value that outweigh any disadvantages,” Dr. Morris continues.

The RANZCP statement does, in fact, stress just this.

All health care professionals need to “be aware of ethical and medicolegal dilemmas” pertaining to affirmative therapy, it indicates. “Psychiatrists should practice within the relevant laws and accepted professional standards in relation to assessing capacity and obtaining consent...”

Dr. Morris hopes there will ultimately be many more checks and balances in place and that courts and clinicians will need to step back and not assume every child who seeks to transition is doing it as a result of pure gender dysphoria.

He predicts that things will end in a compromise. 

“In my view, this compromise will treat children with respect and approach them like any other patient that presents with a condition that requires proper assessment and treatment.”

“In the end, some cases will be transitioned, but there will be fewer than [are] transitioned at the moment,” he predicts.

A new position statement from the Royal Australian and New Zealand College of Psychiatrists (RANZCP) stresses the importance of a mental health evaluation for people with gender dysphoria – in particular for children and adolescents – before any firm decisions are made on whether to prescribe hormonal treatments to transition, or perform surgeries, often referred to as “gender-affirming care.”

“There is a paucity of quality evidence on the outcomes of those presenting with gender dysphoria. In particular, there is a need for better evidence in relation to outcomes for children and young people,” the guidance states.

Because gender dysphoria “is associated with significant distress ... each case should be assessed by a mental health professional, which will frequently be a psychiatrist, with the person at the center of care. It is important the psychological state and context in which gender dysphoria has arisen is explored to assess the most appropriate treatment,” it adds.

The move by the psychiatry body represents a big shift in the landscape regarding recommendations for the treatment of gender dysphoria in Australia and New Zealand.

Asked to explain the new RANZCP position, Philip Morris, MBBS, FRANZCP, said: “The College acknowledged the complexity of the issues and the legitimacy of different approaches.”

Exploration of a patient’s reasons for identifying as transgender is essential, he said in an interview, especially when it comes to young people.

“There may be other reasons for doing it, and we need to look for those, identify them and treat them. This needs to be done before initiating hormones and changing the whole physical nature of the child,” he said.

“A cautious psychotherapy-first approach makes sense. If we can do that with adolescents, then we will take a big step in the right direction,” stressed Dr. Morris, who is president of the National Association of Practising Psychiatrists in Australia.
 

Keira Bell case and Scandinavian stance lead to more open discussion

The rapid rise in gender dysphoria among adolescents in the Western world, referred to as “rapid-onset” or “late-onset” gender dysphoria, has seen a huge increase in the number of natal girls presenting and created frenzied debate that has intensified worldwide in the last 12 months about how to best treat youth with gender dysphoria.

Concerns have arisen that some transgender identification is due to social contagion, and there is a growing number of “detransitioners” – people who identified as transgender, transitioned to the opposite gender, but then regretted their decision, changed their minds, and “detransitioned” back to their birth sex. If they have had hormone therapy, and in some cases surgery, they are left with irreversible changes to their bodies.

As a result, Scandinavian countries, most notably Finland, once eager advocates of the gender-affirmative approach, have pulled back and issued new treatment guidelines in 2020 stating that psychotherapy, rather than gender reassignment, should be the first line of treatment for gender-dysphoric youth.

This, along with a landmark High Court decision in the U.K. regarding the use of puberty-blocking drugs for children with gender dysphoria, brought by detransitioner Keira Bell, which was recently overturned by the Appeal Court, but which Ms. Bell now says she will take to the Supreme Court, has led to a considerable shift in the conversation around treating transgender adolescents with hormonal therapy, says Dr. Morris.

“This [has moved from] ... a topic that could previously not be talked about freely to one that we can discuss more openly now. This is a big improvement. Previously, everyone thought it was all settled, but it’s not, certainly not from a medical angle,” he states.
 

At odds with prior Australian recommendations

The RANZCP had previously endorsed the standard guidelines of the Royal Children’s Hospital (RCH) Melbourne, followed by most gender-identity services in Australia and similar guidance from New Zealand, which both recommend gender-affirming care.

“Increasing evidence demonstrates that with supportive, gender-affirming care during childhood and adolescence, harms can be ameliorated and mental health and well-being outcomes can be significantly improved,” state the RCH guidelines.

But in 2019, RANZCP removed its endorsement of the RCH guidelines and started a consultation, which resulted in the new position statement.

However, Ken Pang, MD, of the Murdoch Children’s Research Institute in Melbourne and an author of the RCH guidelines, says the key recommendations of the new RANZCP position statement are consistent with their own guidelines.

The former note “the need for a skilled mental health clinician in providing comprehensive exploration of a child or adolescent’s biopsychosocial context,” Dr. Pang says.

However, it’s difficult not to see the contrast in stance when the new RANZCP statement maintains: “Research on gender dysphoria is still emerging. There are polarized views and mixed evidence regarding treatment options for people presenting with gender identity concerns, especially children and young people.”

Dr. Pang says the RCH guidelines do, however, recognize the need for further research in the field.

“I look forward to being able to incorporate such research, including from our own Trans20 study, into future revisions of our guidelines,” he told this news organization.
 

Watch your backs with affirmative therapy: Will there be a compromise?

Dr. Morris says there will obviously be cases where “the child might transition with a medical intervention, but that wouldn’t be the first step.”

And yet, he adds, “There are those who push the pro-trans view that everyone should be allowed to transition, and the doctors are only technicians that provide hormones with no questions asked.” 

But from a doctor’s perspective, clinicians will still be held responsible in medical and legal terms for the treatments given, he stressed.

“I don’t think they will ever not be accountable for that. They will always need to determine in their own mind whether their actions have positive value that outweigh any disadvantages,” Dr. Morris continues.

The RANZCP statement does, in fact, stress just this.

All health care professionals need to “be aware of ethical and medicolegal dilemmas” pertaining to affirmative therapy, it indicates. “Psychiatrists should practice within the relevant laws and accepted professional standards in relation to assessing capacity and obtaining consent...”

Dr. Morris hopes there will ultimately be many more checks and balances in place and that courts and clinicians will need to step back and not assume every child who seeks to transition is doing it as a result of pure gender dysphoria.

He predicts that things will end in a compromise. 

“In my view, this compromise will treat children with respect and approach them like any other patient that presents with a condition that requires proper assessment and treatment.”

“In the end, some cases will be transitioned, but there will be fewer than [are] transitioned at the moment,” he predicts.

New research shows that supine orthostatic hypotension is more common and better predicts falls and orthostatic symptoms than seated OH, supporting a supine OH protocol in clinical practice, the researchers say.

“Older adults at risk for falls undergoing assessment for OH should lie supine rather than sitting prior to standing to get the most informative OH assessment,” study author Stephen Juraschek, MD, PhD, Beth Israel Deaconess Medical Center/Harvard Medical School, Boston, said in an interview.

“The findings call for a change in current practice,” Dr. Juraschek said.

He presented the study Sept. 29 at the joint scientific sessions of the American Heart Association Council on Hypertension, AHA Council on Kidney in Cardiovascular Disease, and American Society of Hypertension.

The seated position for detecting OH is “commonly used for convenience. Since many clinics already perform a seated blood pressure, it saves time for people to stand shortly afterward,” he explained.

“It has also been thought that the two are interchangeable [i.e., the change in blood pressure from seated to standing was just a lower magnitude than the change from supine to standing]. However, we showed that the physiology is on average quite different, questioning prior perspectives on the interchangeability of the two protocols,” he added.

The researchers studied 522 adults (mean age, 76 years; 42% women) at high risk for falls and with vitamin D levels in the insufficient/deficient range participating in the Study to Understand Fall Reduction and Vitamin D (STURDY).

The study showed that vitamin D supplementation was not associated with OH or the main study outcome of falls.

The study used two different OH assessment protocols – seated to standing and supine to standing – and Dr. Juraschek’s team used the data to gauge the impact of supine and seated positions on OH prevalence and its relation with fall risk and orthostatic symptoms.

OH was defined as a drop in systolic BP of at least 20 mm Hg or diastolic BP of at least 10 mm Hg.

At baseline, mean BP was 129/68 mm Hg. Mean BP increased 3.4/2.6 mm Hg after sitting, but decreased 3.7/0.7 mm Hg after lying supine.

Of the 953 OH assessments (supine and seated), OH was detected in 14.8% of the supine measurements but in only 2.2% of the seated measures.

Supine OH better predicted falls (hazard ratio, 1.60; 95% CI, 0.98-2.61; P = .06) than seated OH (HR, 0.70; 95% CI, 0.30-1.60; P = .39).

Although both were nonsignificant, “potentially due to power,” the association with falls was stronger for supine OH than for seated OH, Dr. Juraschek said.

In addition, seated OH was not associated with orthostatic symptoms, whereas supine OH was significantly associated with a greater risk of fainting, blacking out, seeing spots, room spinning, and headache in the previous month (P = .048-.002).
 

Useful study confirms anecdotal evidence

This is a “useful study” from a “reputable” group, “and the results reveal what I would have expected,” Robert Carey, MD, University of Virginia, Charlottesville, who wasn’t involved in the study, said in an interview.

The findings, Dr. Carey said, show that measuring supine, compared with standing, “actually correlates much better with the untoward effects of orthostatic hypotension which are falls and symptoms such as dizziness and spots before your eyes.”

“Seated BP is mostly used for convenience and a little bit shorter protocol. Most clinical trials do seated orthostatic hypotension measurements. I’ve always taught my medical students and others to use the supine to standing because I’ve just anecdotally felt that this was a much better way of detecting true orthostatic hypotension and that’s how we do it at the University of Virginia Hospital,” Dr. Carey said.

The study had no funding. Dr. Juraschek and Dr. Carey have no relevant conflicts of interest.

Psychological therapy that changes an individual’s beliefs about pain not only provides lasting chronic pain relief but also alters brain regions related to pain generation, new research shows.

In the first randomized controlled test of pain-reprocessing therapy (PRT), two-thirds of patients with chronic back pain (CBP) who received 4 weeks of PRT were pain free or nearly pain free afterward – and for most patients, relief was maintained for 1 year, the researchers found.

“Primary chronic back pain can be dramatically reduced or even eliminated by psychological treatment focused on changing how threatening we perceive the pain to be,” first author Yoni Ashar, PhD, department of psychiatry, Weill Cornell Medicine, New York, said in an interview.

“We were very surprised” by the impact, Dr. Ashar admitted, given that large reductions in pain have rarely been observed in studies that tested psychological therapies for chronic back pain.

The study was published online Sept. 29, 2021, in JAMA Psychiatry.
 

Rethinking pain

CBP is a leading cause of disability, and treatment is often ineffective. In about 85% of cases of primary CBP, a definitive cause of the pain can’t be identified. In these cases, fear, avoidance, and beliefs that pain indicates injury may contribute to ongoing CBP.

Thinkstock.com

PRT educates patients about the role of the brain in generating chronic pain; helps them reappraise their pain as they engage in movements that they had been afraid to undertake; and helps them address emotions that may exacerbate pain.

The study included 151 adults (54% women; mean age, 41 years) who had primary CBP of low to moderate severity (mean pain intensity, 4 of 10) for an average of 10 years.

A total of 50 participants were randomly allocated to undergo PRT (one telehealth session with a physician and eight PRT sessions over 4 weeks), 51 to receive placebo (subcutaneous saline injection in the back), and 50 to continue their routine, usual ongoing care.

Large group differences in pain were observed after treatment. The mean pain score was 1.18 in the PRT group, 2.84 in the placebo group, and 3.13 in the usual-care group. Hedges’ g was –1.14 for PRT versus placebo and –1.74 for PRT versus usual care (P < .001).

Two-thirds (66%) of adults in the PRT group were pain free or nearly pain free following treatment (pain-intensity score of 0 or 1 out of 10), compared with 20% of those in the placebo group and 10% of those who received usual care.

Treatment effects were maintained at 1-year follow-up. The mean pain score was 1.51 in the PRT group, 2.79 in the placebo group, and 3.00 in the usual-care group. Neither age nor sex moderated the effect of PRT on pain intensity.
 

Retraining the brain

The researchers said the effects of PRT on pain were mediated by lessening the belief that pain indicates tissue damage. Of note, PRT also reduced experimentally evoked back pain and spontaneous pain during functional MRI, with large effect sizes.

“The idea is that by thinking about the pain as safe rather than threatening, patients can alter the brain networks reinforcing the pain, and neutralize it,” Dr. Ashar said in a news release.

The authors noted that study participants were relatively well educated and active. The participants reported having longstanding low to moderate pain and disability at baseline.

The physician and therapists were experts in delivering PRT. Future studies should test generalizability to other patient populations, therapists, and treatment contexts.

“Our clinical experience shows that PRT is effective for other primary chronic pain conditions as well,” said Dr. Ashar, including primary knee pain and tension headache.
 

Restoring function

Commenting on the findings, Shaheen E. Lakhan, MD, PhD, neurologist and pain specialist in Newton, Mass., said he has long experience using psychological approaches to address pain, with good results.

“Imagine telling a person suffering from decades of chronic pain that your pain is all in your head. I’ve done that for years as a board-certified pain physician managing only the most severe and debilitating forms of pain. When used to ground brain retraining, I could ultimately restore function to people living with chronic pain,” Dr. Lakhan said.

“The statement is true – the brain ultimately processes signals from throughout the body, forms the perception of pain, and links it to emotional brain centers, among others. Pain is an important survival mechanism so that when your body is at threat of injury, you protect yourself from further damage and withdraw. The problem lies when pain outlasts its welcome and chronifies,” said Dr. Lakhan, senior vice president of research and development of Click Therapeutics in Boston.

The investigators in this study “eloquently prove” that with 4 weeks of PRT, patients can learn that chronic pain is largely a “brain-generated false alarm and that constantly affirming this truth can actually reduce or eliminate it,” Dr. Lakhan said.

“Further, the brain areas implicated with pain are calmed after going through the therapy to both resting pain and pain induced by extending the back,” he noted.

“Pain-reprocessing therapy can improve the lives of chronic [pain patients] who have low to moderate levels of pain and disability; however, much work needs to be done to make this scalable and universally available and covered by insurers as a treatment modality,” Dr. Lakhan added.

He cautioned that he has not seen therapies such as this work when there is significant depression, withdrawal, or lack of control over one’s situation such that one behaves in a helpless manner – “a terrible state of mind called learned helplessness.”

The study was funded by the National Institutes of Health, the National Center for Advancing Translational Sciences, the Radiological Society of North America, the German Research Foundation, the Psychophysiologic Disorders Association, the Foundation for the Study of the Therapeutic Encounter, and community donations. Dr. Ashar received grants from the National Institutes of Health during the conduct of the study and personal fees from UnitedHealth Group, Lin Health, Pain Reprocessing Therapy Center, and Mental Health Partners of Boulder County outside the submitted work. Dr. Lakhan disclosed no relevant financial relationships.

“The idea is that by thinking about the pain as safe rather than threatening, patients can alter the brain networks reinforcing the pain, and neutralize it,” Dr. Ashar said in a news release.

The authors noted that study participants were relatively well educated and active. The participants reported having longstanding low to moderate pain and disability at baseline.

The physician and therapists were experts in delivering PRT. Future studies should test generalizability to other patient populations, therapists, and treatment contexts.

“Our clinical experience shows that PRT is effective for other primary chronic pain conditions as well,” said Dr. Ashar, including primary knee pain and tension headache.
 

Restoring function

Commenting on the findings, Shaheen E. Lakhan, MD, PhD, neurologist and pain specialist in Newton, Mass., said he has long experience using psychological approaches to address pain, with good results.

“Imagine telling a person suffering from decades of chronic pain that your pain is all in your head. I’ve done that for years as a board-certified pain physician managing only the most severe and debilitating forms of pain. When used to ground brain retraining, I could ultimately restore function to people living with chronic pain,” Dr. Lakhan said.

“The statement is true – the brain ultimately processes signals from throughout the body, forms the perception of pain, and links it to emotional brain centers, among others. Pain is an important survival mechanism so that when your body is at threat of injury, you protect yourself from further damage and withdraw. The problem lies when pain outlasts its welcome and chronifies,” said Dr. Lakhan, senior vice president of research and development of Click Therapeutics in Boston.

The investigators in this study “eloquently prove” that with 4 weeks of PRT, patients can learn that chronic pain is largely a “brain-generated false alarm and that constantly affirming this truth can actually reduce or eliminate it,” Dr. Lakhan said.

“Further, the brain areas implicated with pain are calmed after going through the therapy to both resting pain and pain induced by extending the back,” he noted.

“Pain-reprocessing therapy can improve the lives of chronic [pain patients] who have low to moderate levels of pain and disability; however, much work needs to be done to make this scalable and universally available and covered by insurers as a treatment modality,” Dr. Lakhan added.

He cautioned that he has not seen therapies such as this work when there is significant depression, withdrawal, or lack of control over one’s situation such that one behaves in a helpless manner – “a terrible state of mind called learned helplessness.”

The study was funded by the National Institutes of Health, the National Center for Advancing Translational Sciences, the Radiological Society of North America, the German Research Foundation, the Psychophysiologic Disorders Association, the Foundation for the Study of the Therapeutic Encounter, and community donations.

Psychological therapy that changes an individual’s beliefs about pain not only provides lasting chronic pain relief but also alters brain regions related to pain generation, new research shows.

In the first randomized controlled test of pain-reprocessing therapy (PRT), two-thirds of patients with chronic back pain (CBP) who received 4 weeks of PRT were pain free or nearly pain free afterward – and for most patients, relief was maintained for 1 year, the researchers found.

“Primary chronic back pain can be dramatically reduced or even eliminated by psychological treatment focused on changing how threatening we perceive the pain to be,” first author Yoni Ashar, PhD, department of psychiatry, Weill Cornell Medicine, New York, said in an interview.

“We were very surprised” by the impact, Dr. Ashar admitted, given that large reductions in pain have rarely been observed in studies that tested psychological therapies for chronic back pain.

The study was published online Sept. 29, 2021, in JAMA Psychiatry.
 

Rethinking pain

CBP is a leading cause of disability, and treatment is often ineffective. In about 85% of cases of primary CBP, a definitive cause of the pain can’t be identified. In these cases, fear, avoidance, and beliefs that pain indicates injury may contribute to ongoing CBP.

PRT educates patients about the role of the brain in generating chronic pain; helps them reappraise their pain as they engage in movements that they had been afraid to undertake; and helps them address emotions that may exacerbate pain.

The study included 151 adults (54% women; mean age, 41 years) who had primary CBP of low to moderate severity (mean pain intensity, 4 of 10) for an average of 10 years.

A total of 50 participants were randomly allocated to undergo PRT (one telehealth session with a physician and eight PRT sessions over 4 weeks), 51 to receive placebo (subcutaneous saline injection in the back), and 50 to continue their routine, usual ongoing care.

Large group differences in pain were observed after treatment. The mean pain score was 1.18 in the PRT group, 2.84 in the placebo group, and 3.13 in the usual-care group. Hedges’ g was –1.14 for PRT versus placebo and –1.74 for PRT versus usual care (P < .001).

Two-thirds (66%) of adults in the PRT group were pain free or nearly pain free following treatment (pain-intensity score of 0 or 1 out of 10), compared with 20% of those in the placebo group and 10% of those who received usual care.

Treatment effects were maintained at 1-year follow-up. The mean pain score was 1.51 in the PRT group, 2.79 in the placebo group, and 3.00 in the usual-care group. Neither age nor sex moderated the effect of PRT on pain intensity.

Vancomycin is a widely used IV antibiotic due to its broad-spectrum of activity, bactericidal nature, and low rates of resistance; however, adverse effects (AEs), including nephrotoxicity, are commonly associated with its use.¹ The vancomycin therapeutic monitoring guidelines recognize the incidence of nephrotoxicity and suggest strategies for reducing the risk, including area under the curve/mean inhibitory concentration (AUC/MIC) monitoring rather than trough-only monitoring. Vancomycin-associated acute kidney injury (AKI) has been defined as an increase in serum creatinine (SCr) over a 48-hour period of ≥ 0.3 mg/dL or a percentage increase of ≥ 50%, which is consistent with the Acute Kidney Injury Network (AKIN) guidelines.^2,3 Vancomycin-associated AKI is a common AE, with its incidence reported in previous studies ranging from 10 to 20%.^4,5

The most common crystalloid fluid administered to patients in the United States is 0.9% sodium chloride (NaCl), also known as normal saline (NS), and recent trials have explored its potential to cause AEs.^6-8 Balanced crystalloid solutions, such as Plasma-Lyte and lactated Ringer’s solution (LR), contain buffering agents and lower concentrations of sodium and chloride compared with that of NS. Trials in the intensive care unit (ICU) and emergency department, such as the SMART-MED, SMART-SURG, and SALT-ED have reported a significantly lower rate of AKI when using balanced crystalloids compared with NS due to the concentration of sodium and chloride in NS being supraphysiologic to normal serum concentrations.^6,7 Alternatively, the SPLIT trial evaluated the use of NS compared with Plasma-Lyte for ICU fluid therapy and did not find a statistically significant difference in AKI.⁸ Furthermore, some studies have reported increased risk for hyperchloremia when using NS compared with dextrose 5% in water (D5W) or balanced crystalloids, which can result in metabolic acidosis.^6,7,9,10 These studies have shown how the choice of fluid can have a large effect on the incidence of AEs; bringing into question whether these effects could be additive when combined with the nephrotoxicity associated with vancomycin.^6-9

Vancomycin is physically and chemically stable if diluted in D5W, NS, 5% dextrose in NS, LR, or 5% dextrose in LR.¹ It is not known whether the selection of diluent has an effect on nephrotoxicity or other AEs of vancomycin therapy. Furthermore, clinicians may be unaware or unable to specify which diluent to use. There are currently no practice guidelines that favor one diluent over another for vancomycin; however, trials showing higher rates of AKI and hyperchloremia using NS for fluid resuscitation may indicate an increased potential for vancomycin-associated AKI when using NS as a diluent.^6,7,9 This study was performed to evaluate whether the type of crystalloid used (D5W vs NS) can influence adverse outcomes for patients. While many factors may contribute to these AEs, the potential to reduce the risk of negative adverse outcomes for hospitalized patients is a significant area of exploration.

The primary outcome of this study was the incidence of AKI, defined using AKIN guidelines where the increase in SCr occurred at least 24 hours after starting vancomycin and within 36 hours of receiving the last vancomycin dose.³ AKI was staged using the AKIN guidelines (stage 1: increase in SCr of ≥ 0.3 mg/dL or by 50 to 99%; stage 2: increase in SCr by 100 to 199%; stage 3: increase in SCr by > 200%) based on changes in SCr from baseline during vancomycin therapy or within 36 hours of stopping vancomycin therapy.³ Secondary outcomes included the incidence of hyperglycemia, hyperchloremia, metabolic acidosis, hypernatremia, mortality in hospital, and mortality within 30 days from hospital discharge.

Methods

This single-center, retrospective study of veterans who received IV vancomycin within the North Florida/South Georgia Veterans Health System (NF/SGVHS) in Gainesville, Florida, from July 1, 2015 to June 30, 2020, compared veterans who received vancomycin diluted in NS with those who received vancomycin diluted in D5W to assess for differences in AEs, including AKI, metabolic acidosis (serum bicarbonate level < 23 mmol/L), hyperchloremia (serum chloride levels > 108 mmol/L), hypernatremia (serum sodium > 145 mmol/L), and hyperglycemia (blood glucose > 180 mg/dL). The endpoint values were defined using the reference ranges determined by the local laboratory. At NF/SGVHS, vancomycin is diluted in D5W or NS based primarily on factors such as product availability and cost.

Study Criteria

Veterans were included if they received IV vancomycin between July 1, 2015 and June 30, 2020. The cohorts were grouped into those receiving vancomycin doses diluted in NS and those receiving vancomycin doses diluted in D5W. Veterans were excluded if they received < 80% of vancomycin doses diluted in their respective fluid, if they were on vancomycin for < 48 hours, or if they did not have laboratory results collected both before and after vancomycin therapy to assess a change. There were more patients receiving vancomycin in D5W, so a random sample was selected to have an equal size comparison group with those receiving NS. A sample size calculation was performed with an anticipated AKI incidence of 14%.⁵ To detect a 10% difference in the primary outcome with an α of 0.05 and 75% power, 226 patients (113 in each cohort) were needed for inclusion.

Data were collected using the Data Access Request Tracker tool through the US Department of Veterans Affairs (VA) Informatics and Computing Infrastructure. Data collected included demographics, laboratory data at baseline and during vancomycin therapy, characteristics of antibiotic therapy, and mortality data. Of note, all laboratory values assessed in this study were obtained while the veteran was receiving vancomycin or within 36 hours of receiving the last vancomycin dose to appropriately assess any changes.

Statistical analysis of categorical data were analyzed using a χ² test on the GraphPad online program. This study received institutional review board approval from the University of Florida and was conducted in accordance with protections for human subjects.

Results

A total of 792 veterans received IV vancomycin NF/SGVHS in the defined study period. Of these, 381 veterans were excluded, including having < 80% of doses in a single solution (213 veterans), receiving IV vancomycin for < 48 hours (149 veterans), and not having necessary laboratory data available to assess a change in kidney function (19 veterans). An additional 165 veterans were randomly excluded from the D5W cohort in order to have an equal comparison group to the NS cohort; therefore, a total of 246 veterans were included in the final assessment (123 veterans in each cohort). The median patient age was 73 years (IQR, 68.0, 80.5) in the D5W group and 66 years (IQR, 60.0, 74.0) in the NS group; 83.7% of veterans in the D5W group and 74% veterans in the NS group were white; 94.3% of the D5W group and 100% of the NS group were male (Table 1).

Adverse Effects by Solution

The percentage of AKI in the D5W group was 22.8% compared with 14.6% in the NS group (P = .14), and all cases were classified as stage 1 AKI. Baseline cases of hyperglycemia, hypernatremia, hyperchloremia, or metabolic acidosis were not included in the reported rates of each in order to determine a change during vancomycin therapy (Table 2).

The percentage of patients with hyperglycemia in the D5W group was 32.5% compared with 39.8% in the NS group (P = .29). The percentage of patients with hypernatremia in the D5W group was 15.4% compared with 10.6% in the NS group (P = .34). The percentage of patients with hyperchloremia in the D5W group was 22.8% compared with 17.9% in the NS group (P = .43). The percentage of patients with metabolic acidosis in the D5W group was 48.0% compared with 49.6% in the NS group (P = .90).

Discussion

This retrospective cohort study comparing the AEs of vancomycin diluted in NS and vancomycin diluted with D5W showed no statistically significant differences in the incidence of AKI or any metabolic AEs. Although these results did not show an association between the incidence of AEs and the dilution fluid for vancomycin, other factors may contribute to the overall incidence of AEs. Factors such as cumulative vancomycin dose, duration of therapy, and presence of concomitant nephrotoxins have been known to increase the incidence of AKI and may have a greater impact on this incidence than the fluid used in administering the vancomycin.

These results specifically the incidence of AKI were not consistent with previous trials evaluating the AEs of NS. Based on previous trials, we expected the vancomycin in the NS cohort to have a significantly higher incidence of hypernatremia, hyperchloremia, and AKI. Our results may indicate that the volume of crystalloid received played a greater role on the incidence of AEs. Our study assessed the effect of a diluent for one IV medication that may have been only a few hundred milliliters of fluid per day. The total volume of IV fluid received from vancomycin was not assessed; thus, it is not known how the volume of fluid may have impacted the results.

One consideration with this study is the method used for monitoring vancomycin levels. Most of the patients included in this study were admitted prior to the release of the updated vancomycin guidelines, which advocated for the transition from traditional trough-only monitoring to AUC/MIC. In September 2019, NF/SGVHS ICUs made the transition to this new method of monitoring with a hospital-wide transition following the study end date. The D5W group had a slightly higher percentage of patients admitted to the ICU, thus were more likely to be monitored using AUC/MIC during this period. Literature has shown the AUC/MIC method of monitoring can result in a decreased daily dose, decreased trough levels, and decreased incidence of nephrotoxicity.^11-14 Although the method for monitoring vancomycin has the potential to affect the incidence of AKI, the majority of patients were monitored using the traditional trough-only method with similar trough levels reported in both groups.

Limitations

This study is limited by its retrospective nature, the potential introduction of biases, and the inability to control for confounders that may have influenced the incidence of AEs. Potential confounders present in this study included the use of concomitant nephrotoxic medications, vancomycin dose, and underlying conditions, as these could have impacted the overall incidence of AEs.

The combination of piperacillin/tazobactam plus vancomycin has commonly been associated with an increased risk of nephrotoxicity. Previous studies have identified this nephrotoxic combination to have a significantly increased risk of AKI compared with vancomycin alone or when used in combination with alternative antibiotics such as cefepime or meropenem.^15,16 In our study, there was a higher percentage of patients in the NS group with concomitant piperacillin/tazobactam, so this difference between the groups may have influenced the incidence of AKI. Nephrotoxic medications other than antibiotics were not assessed in this study; however, these also could have impacted our results significantly. While the vancomycin duration of therapy and highest trough levels were similar between groups, the NS group had a larger average daily dose and overall cumulative dose. Studies have identified the risk of nephrotoxicity increases with a vancomycin daily dose of 4 g, troughs > 15 mg/mL, and a duration of therapy > 7 days.^15,16 In our study, the daily doses in both groups were < 4 g, so it is likely the average daily vancomycin dose had little impact on the incidence of AKI.

Another potential confounder identified was assessment of underlying conditions in the patients. Due to the limitations associated with the data extraction method, we could not assess for underlying conditions that may have impacted the results. Notably, the potential nephrotoxicity of NS has mostly been shown in critically ill patients. Therefore, the mixed acutely ill patient sample in this study may have been less likely to develop AKI from NS compared with an exclusively critically ill patient sample.

Selection bias and information bias are common with observational studies. In our study, selection bias may have been present since prospective randomization of patient samples was not possible. Since all data were extracted from the medical health record, information bias may have been present with the potential to impact the results. Due to the single-center nature of this study with a predominantly older, white male veteran patient sample, generalizability to other patient populations may be limited. We would expect the results of this study to be similar among other patient populations of a similar age and demographic; however, the external validity of this study may be weak among other populations. Although this study included enough patients based on sample size estimate, a larger sample size could have allowed for detection of smaller differences between groups and decreased the chance for type II error.

Conclusions

Overall, the results of this study do not suggest that the crystalloid used to dilute IV vancomycin is associated with differences in nephrotoxicity or other relevant AEs. Future studies evaluating the potential for AEs from medication diluent are warranted and would benefit from a prospective, randomized design. Further studies are both necessary and crucial for enhancing the quality of care to minimize the rates of AEs of commonly used medications.

An additional 165 veterans were randomly excluded from the D5W cohort in order to have an equal comparison group to the NS cohort; therefore, a total of 246 veterans were included in the final assessment (123 veterans in each cohort). The median patient age was 73 years (IQR, 68.0, 80.5) in the D5W group and 66 years (IQR, 60.0, 74.0) in the NS group; 83.7% of veterans in the D5W group and 74% veterans in the NS group were white; 94.3% of the D5W group and 100% of the NS group were male (Table 1).

The percentage of patients with metabolic acidosis in the D5W group was 48.0% compared with 49.6% in the NS group (P = .90).

Discussion

This retrospective cohort study comparing the AEs of vancomycin diluted in NS and vancomycin diluted with D5W showed no statistically significant differences in the incidence of AKI or any metabolic AEs. Although these results did not show an association between the incidence of AEs and the dilution fluid for vancomycin, other factors may contribute to the overall incidence of AEs. Factors such as cumulative vancomycin dose, duration of therapy, and presence of concomitant nephrotoxins have been known to increase the incidence of AKI and may have a greater impact on this incidence than the fluid used in administering the vancomycin.

These results specifically the incidence of AKI were not consistent with previous trials evaluating the AEs of NS. Based on previous trials, we expected the vancomycin in the NS cohort to have a significantly higher incidence of hypernatremia, hyperchloremia, and AKI. Our results may indicate that the volume of crystalloid received played a greater role on the incidence of AEs. Our study assessed the effect of a diluent for one IV medication that may have been only a few hundred milliliters of fluid per day. The total volume of IV fluid received from vancomycin was not assessed; thus, it is not known how the volume of fluid may have impacted the results.

One consideration with this study is the method used for monitoring vancomycin levels. Most of the patients included in this study were admitted prior to the release of the updated vancomycin guidelines, which advocated for the transition from traditional trough-only monitoring to AUC/MIC. In September 2019, NF/SGVHS ICUs made the transition to this new method of monitoring with a hospital-wide transition following the study end date. The D5W group had a slightly higher percentage of patients admitted to the ICU, thus were more likely to be monitored using AUC/MIC during this period. Literature has shown the AUC/MIC method of monitoring can result in a decreased daily dose, decreased trough levels, and decreased incidence of nephrotoxicity.^11-14 Although the method for monitoring vancomycin has the potential to affect the incidence of AKI, the majority of patients were monitored using the traditional trough-only method with similar trough levels reported in both groups.

Limitations

This study is limited by its retrospective nature, the potential introduction of biases, and the inability to control for confounders that may have influenced the incidence of AEs. Potential confounders present in this study included the use of concomitant nephrotoxic medications, vancomycin dose, and underlying conditions, as these could have impacted the overall incidence of AEs.

The combination of piperacillin/tazobactam plus vancomycin has commonly been associated with an increased risk of nephrotoxicity. Previous studies have identified this nephrotoxic combination to have a significantly increased risk of AKI compared with vancomycin alone or when used in combination with alternative antibiotics such as cefepime or meropenem.^15,16 In our study, there was a higher percentage of patients in the NS group with concomitant piperacillin/tazobactam, so this difference between the groups may have influenced the incidence of AKI. Nephrotoxic medications other than antibiotics were not assessed in this study; however, these also could have impacted our results significantly. While the vancomycin duration of therapy and highest trough levels were similar between groups, the NS group had a larger average daily dose and overall cumulative dose. Studies have identified the risk of nephrotoxicity increases with a vancomycin daily dose of 4 g, troughs > 15 mg/mL, and a duration of therapy > 7 days.^15,16 In our study, the daily doses in both groups were < 4 g, so it is likely the average daily vancomycin dose had little impact on the incidence of AKI.

Another potential confounder identified was assessment of underlying conditions in the patients. Due to the limitations associated with the data extraction method, we could not assess for underlying conditions that may have impacted the results. Notably, the potential nephrotoxicity of NS has mostly been shown in critically ill patients. Therefore, the mixed acutely ill patient sample in this study may have been less likely to develop AKI from NS compared with an exclusively critically ill patient sample.

Selection bias and information bias are common with observational studies. In our study, selection bias may have been present since prospective randomization of patient samples was not possible. Since all data were extracted from the medical health record, information bias may have been present with the potential to impact the results. Due to the single-center nature of this study with a predominantly older, white male veteran patient sample, generalizability to other patient populations may be limited. We would expect the results of this study to be similar among other patient populations of a similar age and demographic; however, the external validity of this study may be weak among other populations. Although this study included enough patients based on sample size estimate, a larger sample size could have allowed for detection of smaller differences between groups and decreased the chance for type II error.

Conclusions

Overall, the results of this study do not suggest that the crystalloid used to dilute IV vancomycin is associated with differences in nephrotoxicity or other relevant AEs. Future studies evaluating the potential for AEs from medication diluent are warranted and would benefit from a prospective, randomized design. Further studies are both necessary and crucial for enhancing the quality of care to minimize the rates of AEs of commonly used medications.

Vancomycin is a widely used IV antibiotic due to its broad-spectrum of activity, bactericidal nature, and low rates of resistance; however, adverse effects (AEs), including nephrotoxicity, are commonly associated with its use.¹ The vancomycin therapeutic monitoring guidelines recognize the incidence of nephrotoxicity and suggest strategies for reducing the risk, including area under the curve/mean inhibitory concentration (AUC/MIC) monitoring rather than trough-only monitoring. Vancomycin-associated acute kidney injury (AKI) has been defined as an increase in serum creatinine (SCr) over a 48-hour period of ≥ 0.3 mg/dL or a percentage increase of ≥ 50%, which is consistent with the Acute Kidney Injury Network (AKIN) guidelines.^2,3 Vancomycin-associated AKI is a common AE, with its incidence reported in previous studies ranging from 10 to 20%.^4,5

The most common crystalloid fluid administered to patients in the United States is 0.9% sodium chloride (NaCl), also known as normal saline (NS), and recent trials have explored its potential to cause AEs.^6-8 Balanced crystalloid solutions, such as Plasma-Lyte and lactated Ringer’s solution (LR), contain buffering agents and lower concentrations of sodium and chloride compared with that of NS. Trials in the intensive care unit (ICU) and emergency department, such as the SMART-MED, SMART-SURG, and SALT-ED have reported a significantly lower rate of AKI when using balanced crystalloids compared with NS due to the concentration of sodium and chloride in NS being supraphysiologic to normal serum concentrations.^6,7 Alternatively, the SPLIT trial evaluated the use of NS compared with Plasma-Lyte for ICU fluid therapy and did not find a statistically significant difference in AKI.⁸ Furthermore, some studies have reported increased risk for hyperchloremia when using NS compared with dextrose 5% in water (D5W) or balanced crystalloids, which can result in metabolic acidosis.^6,7,9,10 These studies have shown how the choice of fluid can have a large effect on the incidence of AEs; bringing into question whether these effects could be additive when combined with the nephrotoxicity associated with vancomycin.^6-9

Vancomycin is physically and chemically stable if diluted in D5W, NS, 5% dextrose in NS, LR, or 5% dextrose in LR.¹ It is not known whether the selection of diluent has an effect on nephrotoxicity or other AEs of vancomycin therapy. Furthermore, clinicians may be unaware or unable to specify which diluent to use. There are currently no practice guidelines that favor one diluent over another for vancomycin; however, trials showing higher rates of AKI and hyperchloremia using NS for fluid resuscitation may indicate an increased potential for vancomycin-associated AKI when using NS as a diluent.^6,7,9 This study was performed to evaluate whether the type of crystalloid used (D5W vs NS) can influence adverse outcomes for patients. While many factors may contribute to these AEs, the potential to reduce the risk of negative adverse outcomes for hospitalized patients is a significant area of exploration.

The primary outcome of this study was the incidence of AKI, defined using AKIN guidelines where the increase in SCr occurred at least 24 hours after starting vancomycin and within 36 hours of receiving the last vancomycin dose.³ AKI was staged using the AKIN guidelines (stage 1: increase in SCr of ≥ 0.3 mg/dL or by 50 to 99%; stage 2: increase in SCr by 100 to 199%; stage 3: increase in SCr by > 200%) based on changes in SCr from baseline during vancomycin therapy or within 36 hours of stopping vancomycin therapy.³ Secondary outcomes included the incidence of hyperglycemia, hyperchloremia, metabolic acidosis, hypernatremia, mortality in hospital, and mortality within 30 days from hospital discharge.

Methods

This single-center, retrospective study of veterans who received IV vancomycin within the North Florida/South Georgia Veterans Health System (NF/SGVHS) in Gainesville, Florida, from July 1, 2015 to June 30, 2020, compared veterans who received vancomycin diluted in NS with those who received vancomycin diluted in D5W to assess for differences in AEs, including AKI, metabolic acidosis (serum bicarbonate level < 23 mmol/L), hyperchloremia (serum chloride levels > 108 mmol/L), hypernatremia (serum sodium > 145 mmol/L), and hyperglycemia (blood glucose > 180 mg/dL). The endpoint values were defined using the reference ranges determined by the local laboratory. At NF/SGVHS, vancomycin is diluted in D5W or NS based primarily on factors such as product availability and cost.

Study Criteria

Veterans were included if they received IV vancomycin between July 1, 2015 and June 30, 2020. The cohorts were grouped into those receiving vancomycin doses diluted in NS and those receiving vancomycin doses diluted in D5W. Veterans were excluded if they received < 80% of vancomycin doses diluted in their respective fluid, if they were on vancomycin for < 48 hours, or if they did not have laboratory results collected both before and after vancomycin therapy to assess a change. There were more patients receiving vancomycin in D5W, so a random sample was selected to have an equal size comparison group with those receiving NS. A sample size calculation was performed with an anticipated AKI incidence of 14%.⁵ To detect a 10% difference in the primary outcome with an α of 0.05 and 75% power, 226 patients (113 in each cohort) were needed for inclusion.

Data were collected using the Data Access Request Tracker tool through the US Department of Veterans Affairs (VA) Informatics and Computing Infrastructure. Data collected included demographics, laboratory data at baseline and during vancomycin therapy, characteristics of antibiotic therapy, and mortality data. Of note, all laboratory values assessed in this study were obtained while the veteran was receiving vancomycin or within 36 hours of receiving the last vancomycin dose to appropriately assess any changes.

Statistical analysis of categorical data were analyzed using a χ² test on the GraphPad online program. This study received institutional review board approval from the University of Florida and was conducted in accordance with protections for human subjects.

Results

A total of 792 veterans received IV vancomycin NF/SGVHS in the defined study period. Of these, 381 veterans were excluded, including having < 80% of doses in a single solution (213 veterans), receiving IV vancomycin for < 48 hours (149 veterans), and not having necessary laboratory data available to assess a change in kidney function (19 veterans). An additional 165 veterans were randomly excluded from the D5W cohort in order to have an equal comparison group to the NS cohort; therefore, a total of 246 veterans were included in the final assessment (123 veterans in each cohort). The median patient age was 73 years (IQR, 68.0, 80.5) in the D5W group and 66 years (IQR, 60.0, 74.0) in the NS group; 83.7% of veterans in the D5W group and 74% veterans in the NS group were white; 94.3% of the D5W group and 100% of the NS group were male (Table 1).

Adverse Effects by Solution

The percentage of AKI in the D5W group was 22.8% compared with 14.6% in the NS group (P = .14), and all cases were classified as stage 1 AKI. Baseline cases of hyperglycemia, hypernatremia, hyperchloremia, or metabolic acidosis were not included in the reported rates of each in order to determine a change during vancomycin therapy (Table 2).

The percentage of patients with hyperglycemia in the D5W group was 32.5% compared with 39.8% in the NS group (P = .29). The percentage of patients with hypernatremia in the D5W group was 15.4% compared with 10.6% in the NS group (P = .34). The percentage of patients with hyperchloremia in the D5W group was 22.8% compared with 17.9% in the NS group (P = .43). The percentage of patients with metabolic acidosis in the D5W group was 48.0% compared with 49.6% in the NS group (P = .90).

Discussion

This retrospective cohort study comparing the AEs of vancomycin diluted in NS and vancomycin diluted with D5W showed no statistically significant differences in the incidence of AKI or any metabolic AEs. Although these results did not show an association between the incidence of AEs and the dilution fluid for vancomycin, other factors may contribute to the overall incidence of AEs. Factors such as cumulative vancomycin dose, duration of therapy, and presence of concomitant nephrotoxins have been known to increase the incidence of AKI and may have a greater impact on this incidence than the fluid used in administering the vancomycin.

These results specifically the incidence of AKI were not consistent with previous trials evaluating the AEs of NS. Based on previous trials, we expected the vancomycin in the NS cohort to have a significantly higher incidence of hypernatremia, hyperchloremia, and AKI. Our results may indicate that the volume of crystalloid received played a greater role on the incidence of AEs. Our study assessed the effect of a diluent for one IV medication that may have been only a few hundred milliliters of fluid per day. The total volume of IV fluid received from vancomycin was not assessed; thus, it is not known how the volume of fluid may have impacted the results.

One consideration with this study is the method used for monitoring vancomycin levels. Most of the patients included in this study were admitted prior to the release of the updated vancomycin guidelines, which advocated for the transition from traditional trough-only monitoring to AUC/MIC. In September 2019, NF/SGVHS ICUs made the transition to this new method of monitoring with a hospital-wide transition following the study end date. The D5W group had a slightly higher percentage of patients admitted to the ICU, thus were more likely to be monitored using AUC/MIC during this period. Literature has shown the AUC/MIC method of monitoring can result in a decreased daily dose, decreased trough levels, and decreased incidence of nephrotoxicity.^11-14 Although the method for monitoring vancomycin has the potential to affect the incidence of AKI, the majority of patients were monitored using the traditional trough-only method with similar trough levels reported in both groups.

Limitations

This study is limited by its retrospective nature, the potential introduction of biases, and the inability to control for confounders that may have influenced the incidence of AEs. Potential confounders present in this study included the use of concomitant nephrotoxic medications, vancomycin dose, and underlying conditions, as these could have impacted the overall incidence of AEs.

The combination of piperacillin/tazobactam plus vancomycin has commonly been associated with an increased risk of nephrotoxicity. Previous studies have identified this nephrotoxic combination to have a significantly increased risk of AKI compared with vancomycin alone or when used in combination with alternative antibiotics such as cefepime or meropenem.^15,16 In our study, there was a higher percentage of patients in the NS group with concomitant piperacillin/tazobactam, so this difference between the groups may have influenced the incidence of AKI. Nephrotoxic medications other than antibiotics were not assessed in this study; however, these also could have impacted our results significantly. While the vancomycin duration of therapy and highest trough levels were similar between groups, the NS group had a larger average daily dose and overall cumulative dose. Studies have identified the risk of nephrotoxicity increases with a vancomycin daily dose of 4 g, troughs > 15 mg/mL, and a duration of therapy > 7 days.^15,16 In our study, the daily doses in both groups were < 4 g, so it is likely the average daily vancomycin dose had little impact on the incidence of AKI.

Another potential confounder identified was assessment of underlying conditions in the patients. Due to the limitations associated with the data extraction method, we could not assess for underlying conditions that may have impacted the results. Notably, the potential nephrotoxicity of NS has mostly been shown in critically ill patients. Therefore, the mixed acutely ill patient sample in this study may have been less likely to develop AKI from NS compared with an exclusively critically ill patient sample.

Selection bias and information bias are common with observational studies. In our study, selection bias may have been present since prospective randomization of patient samples was not possible. Since all data were extracted from the medical health record, information bias may have been present with the potential to impact the results. Due to the single-center nature of this study with a predominantly older, white male veteran patient sample, generalizability to other patient populations may be limited. We would expect the results of this study to be similar among other patient populations of a similar age and demographic; however, the external validity of this study may be weak among other populations. Although this study included enough patients based on sample size estimate, a larger sample size could have allowed for detection of smaller differences between groups and decreased the chance for type II error.

Conclusions

Overall, the results of this study do not suggest that the crystalloid used to dilute IV vancomycin is associated with differences in nephrotoxicity or other relevant AEs. Future studies evaluating the potential for AEs from medication diluent are warranted and would benefit from a prospective, randomized design. Further studies are both necessary and crucial for enhancing the quality of care to minimize the rates of AEs of commonly used medications.

Yoga is an effective clinical intervention for cancer survivors. Studies indicate a wide range of benefits, including improvements in physical functioning, emotional well-being and overall quality of life.^1-7 Two-thirds of National Cancer Institute designated comprehensive cancer centers offer yoga on-site.⁸ Yoga is endorsed by the National Comprehensive Cancer Network and American Society of Clinical Oncology for managing symptoms, such as cancer-related anxiety and depression and for improving overall quality of life.^9,10

Although the positive effects of yoga on cancer patients are well studied, most published research in this area reports on predominantly middle-aged women with breast cancer.^11,12 Less is known about the use of yoga in other groups of cancer patients, such as older adults, veterans, and those from diverse racial or ethnic backgrounds. This gap in the literature is concerning considering that the majority of cancer survivors are aged 60 years or older, and veterans face unique risk factors for cancer associated with herbicide exposure (eg, Agent Orange) and other military-related noxious exposures.^13,14 Older cancer survivors may have more difficulty recovering from treatment-related adverse effects, making it especially important to target recovery efforts to older adults.¹⁵ Yoga can be adapted for older cancer survivors with age-related comorbidities, similar to adaptations made for older adults who are not cancer survivors but require accommodations for physical limitations.^16-20 Similarly, yoga programs targeted to racially diverse cancer survivors are associated with improved mood and well-being in racially diverse cancer survivors, but studies suggest community engagement and cultural adaptation may be important to address the needs of culturally diverse cancer survivors.^21-23

Yoga has been increasingly studied within the Veterans Health Administration (VHA) for treatment of posttraumatic stress disorder (PTSD) and has been found effective in reducing symptoms through the use of trauma-informed and military-relevant instruction as well as a military veteran yoga teacher.^24-26 This work has not targeted older veterans or cancer survivors who may be more difficult to recruit into such programs, but who would nevertheless benefit.

Clinically, the VHA whole health model is providing increased opportunities for veterans to engage in holistic care including yoga.²⁷ Resources include in-person yoga classes (varies by facility), videos, and handouts with practices uniquely designed for veterans or wounded warriors. As clinicians increasingly refer veterans to these programs, it will be important to develop strategies to engage older veterans in these services.

One important strategy to enhancing access to yoga for older veterans is to consider beliefs about yoga. Beliefs about yoga or general expectations about the outcomes of yoga may be critical to consider in expanding access to yoga in underrepresented groups. Beliefs about yoga may include beliefs about yoga improving health, yoga being difficult or producing discomfort, and yoga involving specific social norms.²⁸ For example, confidence in one’s ability to perform yoga despite discomfort predicted class attendance and practice in a sample of 32 breast cancer survivors.²⁹ Relatedly, positive beliefs about the impact of yoga on health were associated with improvements in mood and quality of life in a sample of 66 cancer survivors.³⁰

The aim of this study was to examine avenues to enhance access to yoga for older veterans, including those from diverse backgrounds, with a focus on the role of beliefs. In the first study we investigate the association between beliefs about and barriers to yoga in a group of older cancer survivors, and we consider the role of demographic and clinical variables in such beliefs and how education may alter beliefs. In alignment with the whole health model of holistic health, we posit that yoga educational materials and resources may contribute to yoga beliefs and work to decrease these barriers. We apply these findings in a second study that enrolled older veterans in yoga and examining the impact of program participation on beliefs and the role of beliefs in program outcomes. In the discussion we return to consider how to increase access to yoga to older veterans based on these findings.

Methods

Study 1 participants were identified from VHA tumor registries. Eligible patients had head and neck, esophageal, gastric, or colorectal cancers and were excluded if they were in hospice care, had dementia, or had a psychotic spectrum disorder. Participants completed a face-to-face semistructured interview at 6, 12, and 18 months after their cancer diagnosis with a trained interviewer. Complete protocol methods, including nonresponder information, are described elsewhere.³¹

Questions about yoga were asked at the 12 month postdiagnosis interview. Participants were read the following: “Here is a list of services some patients use to recover from cancer. Please tell me if you have used any of these.” The list included yoga, physical therapy, occupational therapy, exercise, meditation, or massage therapy. Next participants were provided education about yoga via the following description: “Yoga is a practice of stress reduction and exercise with stretching, holding positions and deep breathing. For some, it may improve your sleep, energy, flexibility, anxiety, and pain. The postures are done standing, sitting, or lying down. If needed, it can be done all from a chair.” We then asked whether they would attend if yoga was offered at the VHA hospital (yes, no, maybe). Participants provided brief responses to 2 open-ended questions: (“If I came to a yoga class, I …”; and “Is there anything that might make you more likely to come to a yoga class?”) Responses were transcribed verbatim and entered into a database for qualitative analysis. Subsequently, participants completed standardized measures of health-related quality of life and beliefs about yoga as described below.

Study 2 participants were identified from VHA tumor registries and a cancer support group. Eligible patients had a diagnosis of cancer (any type except basil cell carcinoma) within the previous 3 years and were excluded if they were in hospice care, had dementia, or had a psychotic spectrum disorder. Participants completed face-to-face semistructured interviews with a trained interviewer before and after participation in an 8-week yoga group that met twice per week. Complete protocol methods are described elsewhere.¹⁶ This paper focuses on 28 of the 37 enrolled patients for whom we have complete pre- and postclass interview data. We previously reported on adaptations made to yoga in our pilot group of 14 individuals, who in this small sample did not show statistically significant changes in their quality of life from before to after the class.¹⁶ This analysis includes those 14 individuals and 14 who participated in additional classes, focusing on beliefs, which were not previously reported.

Measures

Participants reported their age, gender, ethnicity (Hispanic/Latino or not), race, and level of education. Information about the cancer diagnosis, American Joint Committee on Cancer (AJCC) cancer stage, and treatments was obtained from the medical record. The Physical Function and Anxiety Subscales from the Patient-Reported Outcomes Measurement Information System were used to measure health-related quality of life (HRQoL).^32-34 Items are rated on a Likert scale from 1 (not at all) to 5 (very much).

The Beliefs About Yoga Scale (BAYS) was used to measure beliefs about the outcomes of engaging in yoga.²⁸ The 11-item scale has 3 factors: expected health benefits (5 items), expected discomfort (3 items), and expected social norms (3 items). Items from the expected discomfort and expected social norms are reverse scored so that a higher score indicates more positive beliefs. To reduce participant burden, in study 1 we selected 1 item from each factor with high factor loadings in the original cross-validation sample.²⁸ It would improve my overall health (Benefit, factor loading = .89); I would have to be more flexible to take a class (Discomfort, factor loading = .67); I would be embarrassed in a class (Social norms, factor loading = .75). Participants in study 2 completed the entire 11-item scale. Items were summed to create subscales and total scales.

Analysis

Descriptive statistics were used in study 1 to characterize participants’ yoga experience and interest. Changes in interest pre- and posteducation were evaluated with χ² comparison of distribution. The association of beliefs about yoga with 3 levels of interest (yes, no, maybe) was evaluated through analysis of variance (ANOVA) comparing the mean score on the summed BAYS items among the 3 groups. The association of demographic (age, education, race) and clinical factors (AJCC stage, physical function) with BAYS was determined through multivariate linear regression.

For analytic purposes, due to small subgroup sample sizes we compared those who identified as non-Hispanic White adults to those who identified as African American/Hispanic/other persons. To further evaluate the relationship of age to yoga beliefs, we examined beliefs about yoga in 3 age groups (40-59 years [n = 24]; 60-69 years [n = 58]; 70-89 years [n = 28]) using ANOVA comparing the mean score on the summed BAYS items among the 3 groups. In study 2, changes in interest before and after the yoga program were evaluated with paired t tests and repeated ANOVA, with beliefs about yoga prior to class as a covariate. The association of demographic and clinical factors with BAYS was determined as in the first sample through multivariate linear regression, except the variable of race was not included due to small sample size (ie, only 3 individuals identified as persons of color).

Thematic analysis in which content-related codes were developed and subsequently grouped together was applied to the data of 110 participants who responded to the open-ended survey questions in study 1 to further illuminate responses to closed-ended questions.³⁵ Transcribed responses to the open-ended questions were transferred to a spreadsheet. An initial code book with code names, definitions, and examples was developed based on an inductive method by one team member (EA).³⁵ Initially, coding and tabulation were conducted separately for each question but it was noted that content extended across response prompts (eg, responses to question 2 “What might make you more likely to come?” were spontaneously provided when answering question 1), thus coding was collapsed across questions. Next, 2 team members (EA, KD) coded the same responses, meeting weekly to discuss discrepancies. The code book was revised following each meeting to reflect refinements in code names and definitions, adding newly generated codes as needed. The process continued until consensus and data saturation was obtained, with 90% intercoder agreement. Next, these codes were subjected to thematic analysis by 2 team members (EA, KD) combining codes into 6 overarching themes. The entire team reviewed the codes and identified 2 supra themes: positive beliefs or facilitators and negative beliefs or barriers.

Consistent with the concept of reflexivity in qualitative research, we acknowledge the influence of the research team members on the qualitative process.³⁶ The primary coding team (EA, KD) are both researchers and employees of Veterans Affairs Boston Healthcare System who have participated in other research projects involving veterans and qualitative analyses but are not yoga instructors or yoga researchers.

Results

Study 1

The sample of 110 military veterans was mostly male (99.1%) with a mean (SD) age of 64.9 (9.4) years (range, 41-88)(Table 1). The majority (70.9%) described their race/ethnicity as White, non-Hispanic followed by Black/African American (18.2%) and Hispanic (8.2%) persons; 50.0% had no more than a high school education. The most common cancer diagnoses were colorectal (50.9%), head and neck (39.1%), and esophageal and gastric (10.0%) and ranged from AJCC stages I to IV.

When first asked, the majority of participants (78.2%) reported that they were not interested in yoga, 16.4% reported they might be interested, and 5.5% reported they had tried a yoga class since their cancer diagnosis. In contrast, 40.9% used exercise, 32.7% used meditation, 14.5% used physical or occupational therapy, and 11.8% used massage therapy since their cancer diagnosis.

Study 2 Intervention Sample

This sample of 28 veterans was mostly male (96.4%) with a mean (SD) age of 69.2 (10.9) years (range, 57-87). The majority (89.3%) described their race as White, followed by Black/African American (10.7%); no participants self-identified in other categories for race/ethnicity. Twelve veterans (42.9%) had no more than a high school education. The most common cancer diagnosis was genitourinary (35.7%) and the AJCC stage ranged from I to IV.

We employed information learned in study 1 to enhance access in study 2. We mailed letters to 278 veterans diagnosed with cancer in the previous 3 years that provided education about yoga based on study 1 findings. Of 207 veterans reached by phone, 133 (64%) stated they were not interested in coming to a yoga class; 74 (36%) were interested, but 30 felt they were unable to attend due to obstacles such as illness or travel. Ultimately 37 (18%) veterans agreed and consented to the class, and 28 (14%) completed postclass surveys.

In multivariate regression, higher expected health benefits of yoga were associated with higher physical function, lower concern about expected discomfort was also associated with higher physical function as well as higher education; similarly, lower concern about expected social norms was associated with higher physical function. Age was not associated with any of the BAYS factors.

Beliefs about yoga improved from before to after class for all 3 domains with greater expected benefit and lower concerns about discomfort or social norms: expected benefit (mean difference, 5.3; t = 4.44, P < .001), expected discomfort (mean difference, 3.0; t = 4.92, P < .001), expected social norms (mean difference, 3.5; t = 4.38, P < .001). Physical function improved from before the class to afterwards (mean difference, 7.5; t = 3.97, P < .001) but there were no changes in anxiety (mean difference, 0.6; t = 0.76, P = .46). Beliefs about yoga moderated changes in physical function, such that those with higher beliefs experienced a greater improvement in physical function (F = 15.24, P < .001).

Discussion

Yoga is an effective clinical intervention for addressing some long-term adverse effects in cancer survivors, although the body of research focuses predominantly on middle aged, female, White, college-educated breast cancer survivors. There is no evidence to suggest yoga would be less effective in other groups, but it has not been extensively studied in survivors from diverse subgroups. Beliefs about yoga are a factor that may enhance interest in yoga interventions and research, and measures aimed at addressing potential beliefs and fears may capture information that can be used to support older cancer survivors in holistic health. The aims of this study were to examine beliefs about yoga in 2 samples of older cancer survivors who received VHA care. The main findings are (1) interest in yoga was initially low and lower than that of other complementary or exercise-based interventions, but increased when participants were provided brief education about yoga; (2) interest in yoga was associated with beliefs about yoga with qualitative comments illuminating these beliefs; (3) demographic characteristics (education, race) and physical function were associated with beliefs about yoga; and (4) positive beliefs about yoga increased following a brief yoga intervention and was associated with improvements in physical function.

Willingness to consider a class appeared to shift for some older veterans when they were presented brief information about yoga that explained what is involved, how it might help, and that it could be done from a chair if needed. These findings clearly indicated that when trying to enhance participation in yoga in clinical or research programs, it will be important that recruitment materials provide such information. This finding is consistent with the qualitative findings that reflected a lack of knowledge or skepticism about benefits of yoga among some participants. Given the finding that physical function was associated with beliefs about yoga and was also a prominent theme in qualitative analyses, when referring older veterans to yoga it may be useful to explicitly state that yoga may enhance some aspects of physical function and can be adapted for level of physical function or pain limitations. The finding that beliefs about yoga were associated with education also suggests that materials should be presented at all levels of education.

Age was not associated with beliefs about yoga in either study. Importantly, in a more detailed study 1 follow-up analysis, beliefs about yoga were equivalent for aged > 70 years compared with those aged 40 to 69 years. It is not entirely clear why older adults have been underrepresented in studies of yoga in cancer survivors. However, older adults are vastly underrepresented in clinical trials for many health conditions, even though they are more likely to experience many diseases, including cancer.³⁷ A new National Institutes of Health policy requires that individuals of all ages, including older adults, must be included in all human subjects research unless there are scientific reasons not to include them.³⁸ It is therefore imperative to consider strategies to address underrepresentation of older adults.

Limitations

These findings have several limitations. First, participants were homogeneous in age, gender, race/ethnicity and veteran status, which provides a window into this understudied population but limits generalizability and our ability to control across populations. Second, the sample size limited the ability to conduct subgroup and interaction analyses, such as examining potential differential effects of cancer type, treatment, and PTSD on yoga beliefs or to consider the relationship of yoga beliefs with changes in quality of life before and after the yoga intervention in study 2. Additionally, age was not associated with beliefs about yoga in these samples that of mostly older adults. We were able to compare middle-aged and older adults but could not compare beliefs about yoga to adults aged in their 20s and 30s. Last, our study excluded people with dementia and psychotic disorders. Further research is needed to examine yoga for older cancer survivors who have these conditions.

Conclusions

Education that specifically informs potential participants about yoga practice, potential modifications, and potential benefits, as well as adaptations to programs that address physical and logistical barriers may be useful in increasing access to and participation in yoga for older Veterans who are cancer survivors.

This gap in the literature is concerning considering that the majority of cancer survivors are aged 60 years or older, and veterans face unique risk factors for cancer associated with herbicide exposure (eg, Agent Orange) and other military-related noxious exposures.^13,14 Older cancer survivors may have more difficulty recovering from treatment-related adverse effects, making it especially important to target recovery efforts to older adults.¹⁵ Yoga can be adapted for older cancer survivors with age-related comorbidities, similar to adaptations made for older adults who are not cancer survivors but require accommodations for physical limitations.^16-20 Similarly, yoga programs targeted to racially diverse cancer survivors are associated with improved mood and well-being in racially diverse cancer survivors, but studies suggest community engagement and cultural adaptation may be important to address the needs of culturally diverse cancer survivors.^21-23

Yoga has been increasingly studied within the Veterans Health Administration (VHA) for treatment of posttraumatic stress disorder (PTSD) and has been found effective in reducing symptoms through the use of trauma-informed and military-relevant instruction as well as a military veteran yoga teacher.^24-26 This work has not targeted older veterans or cancer survivors who may be more difficult to recruit into such programs, but who would nevertheless benefit.

Clinically, the VHA whole health model is providing increased opportunities for veterans to engage in holistic care including yoga.²⁷ Resources include in-person yoga classes (varies by facility), videos, and handouts with practices uniquely designed for veterans or wounded warriors. As clinicians increasingly refer veterans to these programs, it will be important to develop strategies to engage older veterans in these services.

One important strategy to enhancing access to yoga for older veterans is to consider beliefs about yoga. Beliefs about yoga or general expectations about the outcomes of yoga may be critical to consider in expanding access to yoga in underrepresented groups. Beliefs about yoga may include beliefs about yoga improving health, yoga being difficult or producing discomfort, and yoga involving specific social norms.²⁸ For example, confidence in one’s ability to perform yoga despite discomfort predicted class attendance and practice in a sample of 32 breast cancer survivors.²⁹ Relatedly, positive beliefs about the impact of yoga on health were associated with improvements in mood and quality of life in a sample of 66 cancer survivors.³⁰

The aim of this study was to examine avenues to enhance access to yoga for older veterans, including those from diverse backgrounds, with a focus on the role of beliefs. In the first study we investigate the association between beliefs about and barriers to yoga in a group of older cancer survivors, and we consider the role of demographic and clinical variables in such beliefs and how education may alter beliefs. In alignment with the whole health model of holistic health, we posit that yoga educational materials and resources may contribute to yoga beliefs and work to decrease these barriers. We apply these findings in a second study that enrolled older veterans in yoga and examining the impact of program participation on beliefs and the role of beliefs in program outcomes. In the discussion we return to consider how to increase access to yoga to older veterans based on these findings.

Methods

Study 1 participants were identified from VHA tumor registries. Eligible patients had head and neck, esophageal, gastric, or colorectal cancers and were excluded if they were in hospice care, had dementia, or had a psychotic spectrum disorder. Participants completed a face-to-face semistructured interview at 6, 12, and 18 months after their cancer diagnosis with a trained interviewer. Complete protocol methods, including nonresponder information, are described elsewhere.³¹

Questions about yoga were asked at the 12 month postdiagnosis interview. Participants were read the following: “Here is a list of services some patients use to recover from cancer. Please tell me if you have used any of these.” The list included yoga, physical therapy, occupational therapy, exercise, meditation, or massage therapy. Next participants were provided education about yoga via the following description: “Yoga is a practice of stress reduction and exercise with stretching, holding positions and deep breathing. For some, it may improve your sleep, energy, flexibility, anxiety, and pain. The postures are done standing, sitting, or lying down. If needed, it can be done all from a chair.” We then asked whether they would attend if yoga was offered at the VHA hospital (yes, no, maybe). Participants provided brief responses to 2 open-ended questions: (“If I came to a yoga class, I …”; and “Is there anything that might make you more likely to come to a yoga class?”) Responses were transcribed verbatim and entered into a database for qualitative analysis. Subsequently, participants completed standardized measures of health-related quality of life and beliefs about yoga as described below.

Study 2 participants were identified from VHA tumor registries and a cancer support group. Eligible patients had a diagnosis of cancer (any type except basil cell carcinoma) within the previous 3 years and were excluded if they were in hospice care, had dementia, or had a psychotic spectrum disorder. Participants completed face-to-face semistructured interviews with a trained interviewer before and after participation in an 8-week yoga group that met twice per week. Complete protocol methods are described elsewhere.¹⁶ This paper focuses on 28 of the 37 enrolled patients for whom we have complete pre- and postclass interview data. We previously reported on adaptations made to yoga in our pilot group of 14 individuals, who in this small sample did not show statistically significant changes in their quality of life from before to after the class.¹⁶ This analysis includes those 14 individuals and 14 who participated in additional classes, focusing on beliefs, which were not previously reported.

Measures

Participants reported their age, gender, ethnicity (Hispanic/Latino or not), race, and level of education. Information about the cancer diagnosis, American Joint Committee on Cancer (AJCC) cancer stage, and treatments was obtained from the medical record. The Physical Function and Anxiety Subscales from the Patient-Reported Outcomes Measurement Information System were used to measure health-related quality of life (HRQoL).^32-34 Items are rated on a Likert scale from 1 (not at all) to 5 (very much).

The Beliefs About Yoga Scale (BAYS) was used to measure beliefs about the outcomes of engaging in yoga.²⁸ The 11-item scale has 3 factors: expected health benefits (5 items), expected discomfort (3 items), and expected social norms (3 items). Items from the expected discomfort and expected social norms are reverse scored so that a higher score indicates more positive beliefs. To reduce participant burden, in study 1 we selected 1 item from each factor with high factor loadings in the original cross-validation sample.²⁸ It would improve my overall health (Benefit, factor loading = .89); I would have to be more flexible to take a class (Discomfort, factor loading = .67); I would be embarrassed in a class (Social norms, factor loading = .75). Participants in study 2 completed the entire 11-item scale. Items were summed to create subscales and total scales.

Analysis

Descriptive statistics were used in study 1 to characterize participants’ yoga experience and interest. Changes in interest pre- and posteducation were evaluated with χ² comparison of distribution. The association of beliefs about yoga with 3 levels of interest (yes, no, maybe) was evaluated through analysis of variance (ANOVA) comparing the mean score on the summed BAYS items among the 3 groups. The association of demographic (age, education, race) and clinical factors (AJCC stage, physical function) with BAYS was determined through multivariate linear regression.

For analytic purposes, due to small subgroup sample sizes we compared those who identified as non-Hispanic White adults to those who identified as African American/Hispanic/other persons. To further evaluate the relationship of age to yoga beliefs, we examined beliefs about yoga in 3 age groups (40-59 years [n = 24]; 60-69 years [n = 58]; 70-89 years [n = 28]) using ANOVA comparing the mean score on the summed BAYS items among the 3 groups. In study 2, changes in interest before and after the yoga program were evaluated with paired t tests and repeated ANOVA, with beliefs about yoga prior to class as a covariate. The association of demographic and clinical factors with BAYS was determined as in the first sample through multivariate linear regression, except the variable of race was not included due to small sample size (ie, only 3 individuals identified as persons of color).

Thematic analysis in which content-related codes were developed and subsequently grouped together was applied to the data of 110 participants who responded to the open-ended survey questions in study 1 to further illuminate responses to closed-ended questions.³⁵ Transcribed responses to the open-ended questions were transferred to a spreadsheet. An initial code book with code names, definitions, and examples was developed based on an inductive method by one team member (EA).³⁵ Initially, coding and tabulation were conducted separately for each question but it was noted that content extended across response prompts (eg, responses to question 2 “What might make you more likely to come?” were spontaneously provided when answering question 1), thus coding was collapsed across questions. Next, 2 team members (EA, KD) coded the same responses, meeting weekly to discuss discrepancies. The code book was revised following each meeting to reflect refinements in code names and definitions, adding newly generated codes as needed. The process continued until consensus and data saturation was obtained, with 90% intercoder agreement. Next, these codes were subjected to thematic analysis by 2 team members (EA, KD) combining codes into 6 overarching themes. The entire team reviewed the codes and identified 2 supra themes: positive beliefs or facilitators and negative beliefs or barriers.

Consistent with the concept of reflexivity in qualitative research, we acknowledge the influence of the research team members on the qualitative process.³⁶ The primary coding team (EA, KD) are both researchers and employees of Veterans Affairs Boston Healthcare System who have participated in other research projects involving veterans and qualitative analyses but are not yoga instructors or yoga researchers.

Results

Study 1

The sample of 110 military veterans was mostly male (99.1%) with a mean (SD) age of 64.9 (9.4) years (range, 41-88)(Table 1). The majority (70.9%) described their race/ethnicity as White, non-Hispanic followed by Black/African American (18.2%) and Hispanic (8.2%) persons; 50.0% had no more than a high school education. The most common cancer diagnoses were colorectal (50.9%), head and neck (39.1%), and esophageal and gastric (10.0%) and ranged from AJCC stages I to IV.

When first asked, the majority of participants (78.2%) reported that they were not interested in yoga, 16.4% reported they might be interested, and 5.5% reported they had tried a yoga class since their cancer diagnosis. In contrast, 40.9% used exercise, 32.7% used meditation, 14.5% used physical or occupational therapy, and 11.8% used massage therapy since their cancer diagnosis.

Study 2 Intervention Sample

This sample of 28 veterans was mostly male (96.4%) with a mean (SD) age of 69.2 (10.9) years (range, 57-87). The majority (89.3%) described their race as White, followed by Black/African American (10.7%); no participants self-identified in other categories for race/ethnicity. Twelve veterans (42.9%) had no more than a high school education. The most common cancer diagnosis was genitourinary (35.7%) and the AJCC stage ranged from I to IV.

We employed information learned in study 1 to enhance access in study 2. We mailed letters to 278 veterans diagnosed with cancer in the previous 3 years that provided education about yoga based on study 1 findings. Of 207 veterans reached by phone, 133 (64%) stated they were not interested in coming to a yoga class; 74 (36%) were interested, but 30 felt they were unable to attend due to obstacles such as illness or travel. Ultimately 37 (18%) veterans agreed and consented to the class, and 28 (14%) completed postclass surveys.

In multivariate regression, higher expected health benefits of yoga were associated with higher physical function, lower concern about expected discomfort was also associated with higher physical function as well as higher education; similarly, lower concern about expected social norms was associated with higher physical function. Age was not associated with any of the BAYS factors.

Beliefs about yoga improved from before to after class for all 3 domains with greater expected benefit and lower concerns about discomfort or social norms: expected benefit (mean difference, 5.3; t = 4.44, P < .001), expected discomfort (mean difference, 3.0; t = 4.92, P < .001), expected social norms (mean difference, 3.5; t = 4.38, P < .001). Physical function improved from before the class to afterwards (mean difference, 7.5; t = 3.97, P < .001) but there were no changes in anxiety (mean difference, 0.6; t = 0.76, P = .46). Beliefs about yoga moderated changes in physical function, such that those with higher beliefs experienced a greater improvement in physical function (F = 15.24, P < .001).

Discussion

Yoga is an effective clinical intervention for addressing some long-term adverse effects in cancer survivors, although the body of research focuses predominantly on middle aged, female, White, college-educated breast cancer survivors. There is no evidence to suggest yoga would be less effective in other groups, but it has not been extensively studied in survivors from diverse subgroups. Beliefs about yoga are a factor that may enhance interest in yoga interventions and research, and measures aimed at addressing potential beliefs and fears may capture information that can be used to support older cancer survivors in holistic health. The aims of this study were to examine beliefs about yoga in 2 samples of older cancer survivors who received VHA care. The main findings are (1) interest in yoga was initially low and lower than that of other complementary or exercise-based interventions, but increased when participants were provided brief education about yoga; (2) interest in yoga was associated with beliefs about yoga with qualitative comments illuminating these beliefs; (3) demographic characteristics (education, race) and physical function were associated with beliefs about yoga; and (4) positive beliefs about yoga increased following a brief yoga intervention and was associated with improvements in physical function.

Willingness to consider a class appeared to shift for some older veterans when they were presented brief information about yoga that explained what is involved, how it might help, and that it could be done from a chair if needed. These findings clearly indicated that when trying to enhance participation in yoga in clinical or research programs, it will be important that recruitment materials provide such information. This finding is consistent with the qualitative findings that reflected a lack of knowledge or skepticism about benefits of yoga among some participants. Given the finding that physical function was associated with beliefs about yoga and was also a prominent theme in qualitative analyses, when referring older veterans to yoga it may be useful to explicitly state that yoga may enhance some aspects of physical function and can be adapted for level of physical function or pain limitations. The finding that beliefs about yoga were associated with education also suggests that materials should be presented at all levels of education.

Age was not associated with beliefs about yoga in either study. Importantly, in a more detailed study 1 follow-up analysis, beliefs about yoga were equivalent for aged > 70 years compared with those aged 40 to 69 years. It is not entirely clear why older adults have been underrepresented in studies of yoga in cancer survivors. However, older adults are vastly underrepresented in clinical trials for many health conditions, even though they are more likely to experience many diseases, including cancer.³⁷ A new National Institutes of Health policy requires that individuals of all ages, including older adults, must be included in all human subjects research unless there are scientific reasons not to include them.³⁸ It is therefore imperative to consider strategies to address underrepresentation of older adults.

Limitations

These findings have several limitations. First, participants were homogeneous in age, gender, race/ethnicity and veteran status, which provides a window into this understudied population but limits generalizability and our ability to control across populations. Second, the sample size limited the ability to conduct subgroup and interaction analyses, such as examining potential differential effects of cancer type, treatment, and PTSD on yoga beliefs or to consider the relationship of yoga beliefs with changes in quality of life before and after the yoga intervention in study 2. Additionally, age was not associated with beliefs about yoga in these samples that of mostly older adults. We were able to compare middle-aged and older adults but could not compare beliefs about yoga to adults aged in their 20s and 30s. Last, our study excluded people with dementia and psychotic disorders. Further research is needed to examine yoga for older cancer survivors who have these conditions.

Conclusions

Education that specifically informs potential participants about yoga practice, potential modifications, and potential benefits, as well as adaptations to programs that address physical and logistical barriers may be useful in increasing access to and participation in yoga for older Veterans who are cancer survivors.
