A 49-year-old woman, previously recuperating from COVID-19, was found unconscious at her workplace, setting off a chain of events that would ultimately lead to an unexpected diagnosis.

This case report was published in the New England Journal of Medicine.

Noting the patient’s confusion and aphasia, emergency medical services were alerted, and she was taken to the emergency department of Massachusetts General Hospital. Initial examination revealed aphasia and coordination difficulties. However, imaging studies, including CT angiography, showed no signs of stroke or other neurological abnormalities.

The patient’s coworkers had observed that she appeared “unwell.” Her medical history included hypertension, which was managed with amlodipine, and there was no known family history of neurologic disorders.

During the examination, her vital signs were within normal ranges.

The patient’s potassium level of 2.5 mmol/L was noteworthy, indicating hypokalemia. Additionally, the patient presented with anemia and thrombocytopenia. Additional laboratory results unveiled thrombotic thrombocytopenic purpura (TTP), a rare blood disorder characterized by microangiopathic hemolytic anemia. The microscopic examination of a peripheral blood smear confirmed the extent of thrombocytopenia and was particularly notable for the increased number of schistocytes. The patient’s peripheral blood smear revealed five or six schistocytes per high-power field, constituting approximately 5% of the red cells. This significant number of schistocytes aligned with the severity of anemia and thrombocytopenia, confirming the diagnosis of microangiopathic hemolytic anemia.

Acquired TTP is an autoimmune condition driven by antibody-mediated clearance of the plasma enzyme ADAMTS13 (a disintegrin and metalloproteinase with thrombospondin motif 13). Confirmatory laboratory testing for ADAMTS13 takes 1-3 days; therefore, therapeutic plasma exchange with glucocorticoid therapy and rituximab was initiated, which promptly improved her condition.

In this patient, the ADAMTS13 activity level was severely reduced (< 5%; reference value > 67%), and the inhibitor was present (1.4 inhibitor units; reference value ≤ 0.4).

Rectal cancer was diagnosed in this patient 2 months after the diagnosis of acquired TTP.

After undergoing four weekly infusions of rituximab and a 2-month tapering course of glucocorticoids, the patient experienced a relapse, approximately 6 months following the acquired TTP diagnosis. In response, therapeutic plasma exchange and glucocorticoid therapy were administered. There is a possibility that the underlying cancer played a role in the relapse. To minimize the risk for recurrence, the patient also received a second round of rituximab.

While establishing a clear cause is difficult, acquired TTP often appears to arise in connection with either an immune trigger, such as a viral infection, or immune dysregulation associated with another autoimmune disease or ongoing cancer. In this case, 4 weeks before the acquired TTP diagnosis, the patient had experienced COVID-19, which was likely to be the most probable trigger. However, rectal cancer was also identified in the patient, and whether these conditions are directly linked remains unclear.

Making medications more accessible to those who need them is the focus of attention in the media and in all levels of government. For a drug to be accessible, it must be affordable and available. Something may be affordable, but if it isn’t available, no one will have access to it. Think of toilet paper in the first year of the COVID pandemic. The opposite is also true. An item may be available, but if it isn’t affordable, access is lost. While medication affordability is viewed as the major problem for patients, lack of availability has begun to creep into our drug supply chain. We are now experiencing drug shortages for medications that are very affordable. The perverse incentives, inherent in formulary construction, favor higher-priced medications, which decreases the availability of lower-priced – yet still expensive – drugs, thus increasing patient cost share. Formulary placement and patient cost share, important determinants of accessibility, are controlled by health plans and differ considerably even from the same payer. And yet, the price of drugs remains the target of most approaches to increasing patients’ access. And now price negotiations and drug affordability boards enter into the picture.

What are prescription drug affordability boards?

Both state and federal legislatures have placed the affordability of medications front and center on their agendas. However, neither are considering how formulary construction affects patient’s access to medications. The Inflation Reduction Act is Congress’s foray into price setting/negotiation of expensive drugs. Over the last few years, states are also attempting to make drugs more affordable by creating prescription drug affordability boards (PDABs). Governors (or other state leaders) appoint PDAB members who are charged with the task of evaluating the affordability of certain drugs for both the state and its residents. How to do it, and what the limitations are, vary from state to state. In 2019, Maryland was first state to establish a PDAB, charging its members to study commercial insurance and drug pricing and make recommendations on how to make drugs more affordable for Maryland residents. Other states that have passed PDAB legislation are Colorado, Maine, Minnesota, New Hampshire, Ohio, Oregon, and Washington.

Colorado, Minnesota, and Washington – and soon Maryland and Oregon – hope to make drugs more affordable for patients by allowing their PDABs to set an upper payment limit (UPL). A UPL serves as a cap on the sales price and reimbursement for a drug. The Michigan legislature is actively debating legislation that would establish a PDAB and allow it to set UPLs. On the surface, this may appear to be a potential solution to the affordability issue. However, as always, there are many questions as to how this will work and what are the unintended consequences of price setting and establishing UPLs for medications. UPLs have the potential to harm access to provider-administered drugs. With the help of advocacy from the Coalition of State Rheumatology Organizations (CSRO), Washington’s PDAB statute potentially has a carve-out for provider-administered drugs.
 

Possible unintended consequences for provider-administered drugs

CSRO asked for a meeting with the Colorado PDAB after they announced their list of drugs for which UPLs would be set. We spoke with the PDAB in October, hoping to point out some of the unintended consequences that needed to be considered. One of the big questions we have revolves around the “buy and bill” provider-administered drugs. According to the language of the Colorado statute, providers would not be paid any more than the UPL for a drug administered in their office. CSRO is concerned that this would leave providers uncompensated for the service of administering the drug and associated overhead. This is not to mention that providers may not be able to find a group purchasing organization that would even sell the drug at the UPL, much less a lower price than the UPL. And even if a provider could buy it at the UPL, that would mean there would be no margin to cover the overhead for their infusion suite. Interestingly, while Colorado’s rules for the UPL state that pharmacies can be paid an additional reasonable dispensing fee beyond the UPL, no such allowance is made for providers administering one of these medications. In fact, the Colorado PDAB specifically indicated that the goal of the state’s UPL methodology was to ensure that there was no “delta” between what is paid for the drug by the provider and what is reimbursed to a provider for the drug by the payer. This may cause some providers to be unable to “afford” to administer those drugs with UPLs, which ultimately reduces access for residents of Colorado to that particular medication. This is the exact opposite of what the PDAB is supposed to accomplish.

There are still many questions. What impact will UPLs have on a medication’s placement on a formulary? As we know, preferred formulary placement is often given to drugs with the highest price concession from the manufacturers. Will setting a UPL on payment for specialty pharmacy drugs to pharmacy benefit manager-owned specialty pharmacies affect that drug’s ability to be on the formulary? And again, how will the PDAB resolve the issue of compensating the provider for overhead costs associated with administering the medication?

Even more confusing questions remain. How will the UPL be enforced when a “purchase” or “sale” of the drug is made by an out-of-state entity somewhere along the supply chain? When ultimately the drug is purchased and delivered to a Colorado consumer by a Colorado provider/pharmacy, there are multiple points of the supply chain that may be outside of the jurisdiction of Colorado to enforce the UPL. This would create a misalignment in pricing among various supply chain entities.

While the sentiment behind creating PDABs is noble, it may end up having the unintended consequence of patients losing access to these drugs because of the perverse incentives involved in formulary construction or providers’ inability to afford to offer provider-administered drugs with UPLs.

Remember, expensive specialty pharmacy medications are already discounted greatly by manufacturers, often more than 50% to pharmacy benefit managers; and yet those cost savings are not passed on to the patients. Also, there is no oversight of 340B hospital contracted pharmacies to make sure that they pass those savings on to needy patients. Perhaps PDABs should address those issues, as well, if patient access to expensive medications is the goal.

Clearly, there are no easy answers. But with so many variables in the drug supply chain affecting patient access, concentrating only on one aspect may end up causing more harm than good. If your state is thinking of passing a PDAB, please let your legislators know that there are issues with this type of legislation that perhaps should be worked out before the bill is passed.

A meta-analysis appears to allay concerns that surgeons might be performing total knee arthroplasties (TKA) on healthier patients.

“Both the total number [of surgeons performing primary TKA] and the number of surgeons per capita have been generally increasing,” wrote Peter Dust, MD, of McGill University, Montreal, and coauthors. “Reassuringly, however, our results suggest that despite the increasing number of surgeons, the indications for surgery are not being eroded by operating on healthier patients to fill operating room time.”

The study was published in the Canadian Journal of Surgery.
 

Rising demand

In the paper, Dr. Dust and colleagues noted that there was a 162% increase in volume of total knee arthroplasties among people enrolled in the Medicare program between 1991 and 2010.

Unrelated to the study, the Canadian Institute for Health Information (CIHI) has reported similar trends. In 2018-2019, about 75,000 knee replacements were performed in Canada; an increase of 22.5% over the previous 5 years. The numbers dropped in 2020-2021 during the pandemic because of limited access to medical facilities during that time, but then rebounded between April and September 2022 to close to prepandemic numbers. However, about 50% of patients were waiting longer during that time than the recommended 6 months (182 days) for their surgery.
 

So, what’s happening?

The trends for rising numbers of knee surgeries cannot be fully explained by population growth and increasing rates of obesity, Dr. Dust and colleagues wrote. That led them to ask whether some patients were undergoing surgery with a higher level of preoperative function compared with the past.

They conducted a systematic review and meta-analysis of the MEDLINE, Embase, and Cochrane databases with the aim of determining the effect of time, age, and sex on preoperative functional status. A total of 149 studies were ultimately included in the study, with data from 257 independent groups and 57,844 patients recruited from 1991 to 2015.

The analysis revealed that patients are undergoing TKA with a level of preoperative function similar to that in the past. Also, patient age, sex, and location did not influence the functional status at which patients were considered for surgery.

Jasvinder Singh, MD, professor of medicine and epidemiology at University of Alabama at Birmingham, who was not involved with the research, offered another suggestion to explain the trend: People today are more familiar with knee replacement surgery and thus find it a less daunting option.

“Everybody knows somebody who has had a knee done or a hip done,” Singh said in an interview.”People are a lot more familiar with these things than they were 30 years ago.”
 

Subjective criteria persists

In the paper, Dr. Dust said that he and his colleagues had hoped this study might reveal a target physical component summary (PCS) score, used to assess functional status, based on which patients could be considered for surgery. Their findings, however, did not enable such a recommendation to be made.

In an interview, Claudette M. Lajam, MD, a spokesperson for the American Academy of Orthopedic Surgeons (AAOS), agreed that there does not appear to be a trend toward earlier intervention. Also, a precise number or score that can be used to determine when patients should undergo TKA still does not exist. Dr. Lajam is professor of orthopedic surgery and system chief for orthopedic quality and risk at NYU Langone Health, New York.

The “sweet spot time” for TKA is still not clear based on available metrics, Dr. Lajam said. Physicians need to consider not only patient level of function before surgery, but also when to intervene so they will get the most benefit from these procedures.

The knee has to be “bad enough to justify major surgery,” she said, while waiting too long might lead to inferior outcomes.

In time, she thinks artificial intelligence (AI) could help in identifying when primary care clinicians should advise patients to seek specialist care for ailing knees.

AI could allow physicians and researchers to search for clues about the best timing for surgery by combing through millions of x-rays, a variety of functional scores used in assessing patients, and other sources of information, she explained. At this time, the PCS used by Dr. Dust and colleagues is just one of many measures used to assess patient level of function. AI might be able to bring these data together for scientists to review.

“AI can see patterns that I can’t see right now,” Dr. Lajam said.

But she emphasized that any AI application would be an aid to physicians in counseling patients. Evaluation by an experienced surgeon, together with guidance from any AI tool, could provide a greater understanding of how TKA could help patients with arthritis of the knee.

“The physician sees intangibles that AI would not see because we actually talk to the patient,” she explained.

Dr. Dust said there was no outside funding for the study and the authors and Dr. Lajam reported no relevant financial relationships. Dr. Singh said he has received consulting fees from AstraZeneca and institutional research support from Zimmer Biomet Holdings. He has received food and beverage payments from Intuitive Surgical Inc./Philips Electronics North America, and owns stock options in Atai Life Sciences. He is a member of the executive committee of Outcome Measures in Rheumatology (OMERACT), an organization that receives arms-length funding from eight companies.

In 2018-2019, about 75,000 knee replacements were performed in Canada; an increase of 22.5% over the previous 5 years. The numbers dropped in 2020-2021 during the pandemic because of limited access to medical facilities during that time, but then rebounded between April and September 2022 to close to prepandemic numbers. However, about 50% of patients were waiting longer during that time than the recommended 6 months (182 days) for their surgery.
 

So, what’s happening?

The trends for rising numbers of knee surgeries cannot be fully explained by population growth and increasing rates of obesity, Dr. Dust and colleagues wrote. That led them to ask whether some patients were undergoing surgery with a higher level of preoperative function compared with the past.

They conducted a systematic review and meta-analysis of the MEDLINE, Embase, and Cochrane databases with the aim of determining the effect of time, age, and sex on preoperative functional status. A total of 149 studies were ultimately included in the study, with data from 257 independent groups and 57,844 patients recruited from 1991 to 2015.

The analysis revealed that patients are undergoing TKA with a level of preoperative function similar to that in the past. Also, patient age, sex, and location did not influence the functional status at which patients were considered for surgery.

Jasvinder Singh, MD, professor of medicine and epidemiology at University of Alabama at Birmingham, who was not involved with the research, offered another suggestion to explain the trend: People today are more familiar with knee replacement surgery and thus find it a less daunting option.

“Everybody knows somebody who has had a knee done or a hip done,” Singh said in an interview.”People are a lot more familiar with these things than they were 30 years ago.”
 

Subjective criteria persists

In the paper, Dr. Dust said that he and his colleagues had hoped this study might reveal a target physical component summary (PCS) score, used to assess functional status, based on which patients could be considered for surgery. Their findings, however, did not enable such a recommendation to be made.

In an interview, Claudette M. Lajam, MD, a spokesperson for the American Academy of Orthopedic Surgeons (AAOS), agreed that there does not appear to be a trend toward earlier intervention. Also, a precise number or score that can be used to determine when patients should undergo TKA still does not exist. Dr. Lajam is professor of orthopedic surgery and system chief for orthopedic quality and risk at NYU Langone Health, New York.

The “sweet spot time” for TKA is still not clear based on available metrics, Dr. Lajam said. Physicians need to consider not only patient level of function before surgery, but also when to intervene so they will get the most benefit from these procedures.

The knee has to be “bad enough to justify major surgery,” she said, while waiting too long might lead to inferior outcomes.

In time, she thinks artificial intelligence (AI) could help in identifying when primary care clinicians should advise patients to seek specialist care for ailing knees.

AI could allow physicians and researchers to search for clues about the best timing for surgery by combing through millions of x-rays, a variety of functional scores used in assessing patients, and other sources of information, she explained. At this time, the PCS used by Dr. Dust and colleagues is just one of many measures used to assess patient level of function. AI might be able to bring these data together for scientists to review.

“AI can see patterns that I can’t see right now,” Dr. Lajam said.

But she emphasized that any AI application would be an aid to physicians in counseling patients. Evaluation by an experienced surgeon, together with guidance from any AI tool, could provide a greater understanding of how TKA could help patients with arthritis of the knee.

“The physician sees intangibles that AI would not see because we actually talk to the patient,” she explained.

Dr. Dust said there was no outside funding for the study and the authors and Dr. Lajam reported no relevant financial relationships. Dr. Singh said he has received consulting fees from AstraZeneca and institutional research support from Zimmer Biomet Holdings. He has received food and beverage payments from Intuitive Surgical Inc./Philips Electronics North America, and owns stock options in Atai Life Sciences. He is a member of the executive committee of Outcome Measures in Rheumatology (OMERACT), an organization that receives arms-length funding from eight companies.

A meta-analysis appears to allay concerns that surgeons might be performing total knee arthroplasties (TKA) on healthier patients.

“Both the total number [of surgeons performing primary TKA] and the number of surgeons per capita have been generally increasing,” wrote Peter Dust, MD, of McGill University, Montreal, and coauthors. “Reassuringly, however, our results suggest that despite the increasing number of surgeons, the indications for surgery are not being eroded by operating on healthier patients to fill operating room time.”

The study was published in the Canadian Journal of Surgery.

SAN DIEGO – The Spondyloarthritis Research and Treatment Network (SPARTAN) has created the first referral recommendations for axial spondyloarthritis (axSpA).

The draft recommendations use a points scoring system, with the goal that at least one in three patients referred would be diagnosed with axSpA, an inflammatory arthritis that affects the central skeleton and shares a genetic overlap with skin psoriasis, inflammatory bowel disease, and inflammatory eye disease.

Lucy Hicks/Medscape Medical News

Patients with axSpA can wait 10 years after symptom onset to be diagnosed with the condition. There are currently no guidelines to advise clinicians on when to refer to a rheumatologist, and with the rheumatology workforce shortage, “it is impossible for rheumatologists to evaluate the 20% of adults in the U.S. who have chronic back pain,” said Maureen Dubreuil, MD, a rheumatologist at Boston University. She presented the work at the annual meeting of the American College of Rheumatology. 

To address this issue, Dr. Dubreuil and colleagues conducted a literature review to determine how predictive different spondyloarthritis features were of eventual axSpA diagnosis. The interdisciplinary team identified 38 studies published before March 2022, and uncovered 28 individual potential features associated with axSpA, including pain sites, family history of axSpA and related conditions, blood markers of inflammation, genetic testing, and imaging findings.

Inflammatory back pain elements had the lower predictive values, with positive likelihood ratios (LR+) ranging from 1.15 to 2.32, while imaging findings were the most predictive (LR+s from 6.40 to 10.02).

Using a Delphi exercise and discrete choice experiments, members narrowed the checklist down to 10 features. These 10 features were assigned points, with a score of 3 points qualifying for a referral of adults 45 years or younger with chronic pain (3 or more months) in the back, hip, or buttock.

“I went to the woods because I wished to live deliberately, to front only the essential facts of life, and see if I could not learn what it had to teach.” – Henry David Thoreau

I have many patients like Maxine. Tall, with a shock of white hair. Old, but still in charge. When you try to make eye contact, she looks right through you. First with her left eye. Then her right. Her face is inscrutable. What’s she thinking? Unlike many of my patients, however, this Maxine was a llama. Every morning my daughter and I tried to coax her into moving as we leaned on the cold steel gate that kept her in her pasture. We were visiting family in October and chose to stay on a working New England farm. The kids will love the animals, we thought, and we’ll appreciate the extra bedrooms.

Jeffrey Benabio, MD, MBA

Airbnb helped us find this charming fiber-farm in Rhode Island where they raise Leicester Longwool sheep, a historic breed that once roamed George Washington’s pastures, along with a few goats, ducks, chickens, and Maxine. It’s situated deep in the woods, which were yellow, orange, and red that week. As it happens, we were just a short drive due south of Walden Pond where Henry David Thoreau spent 2 years, 2 months and 2 days escaping “overcivilization” nearly 175 years ago. Hoisting our overweight bags over the uneven granite stone steps when we arrived, I realized this was going to be more like the Thoreau experiment than I intended. The farmhouse dated to the 1790s. There were wide, creaky floorboards, low ceilings, one staircase to the bedrooms (which could have aptly been called a ladder) and loads of book-laden shelves. Instructions posted in the kitchen warned that the heat is tricky to regulate – a redundant admonition as we watched our 3-year-old putting on her socks and shoes as she got into bed.

Now, if you’ve ever been on vacation with little kids, you know that it’s basically just childcare in a novel location. After barricading the staircase with luggage and unplugging lamps from their dicey outlets we set out to feed the chickens and try to pet a sheep. Walking the perimeter of the farm we saw stone walls that needed mending and stumbled across two ancient cemeteries, one had been for family, the other for slaves. I wondered how many farmers and weavers and menders had walked this trail with their kids over the generations.

The next morning, we learned that roosters do not in fact crow at dawn, they crow before dawn (which could also aptly be called nighttime). There were no commutes or late patients here. But there was work to be done. Chickens don’t care that it’s Sunday. It downpoured. Watching the sheep from the kitchen as I sipped my coffee, they didn’t seem to mind. Nor did our farmer hosts who trudged past them in tall boots, just as they had every other day of their farmer lives.

Kaiser Permanente

By the fifth day, we had fallen into the rhythms of the homestead. We cracked the blue, green, and brown eggs that our hosts placed outside our door in the early hours and made omelets that were as orange as the foliage. We finally learned to adjust the heat so we neither got chilblains nor had to open the windows and strip naked to cool down. The sky was a brilliant blue that last morning and Sloan ran around trying to catch leaves as they blew off the trees. She had no objective. No counting. No contest. Just chasing leaves as they fell. It was the ultimate atelic activity, done just for doing it. I joined her and found I was no better at this than a 3-year-old.

We came to see family and a few animals and we left with a new appreciation for the goodness of people and nature. Perhaps it’s time to bring back Transcendentalism again? We might all benefit from a little time in the woods.

SAN DIEGO – Even when taken at low doses and over short periods, glucocorticoids (GCs) were linked to a higher risk of major adverse cardiovascular events (MACE) over the long term in a Veterans Affairs population of older, mostly male patients with rheumatoid arthritis, a new retrospective cohort study has found.

The analysis of nearly 19,000 patients, presented by rheumatologist Beth Wallace, MD, MSc, at the annual meeting of the American College of Rheumatology, showed that the level of risk for MACE rose with the dose, duration, and recency of GC use, in which risk increased significantly at prednisone-equivalent doses as low as 5 mg/day, durations as short as 30 days, and with last use as long as 1 year before MACE.

University of Michigan

“Up to half of RA patients in the United States use long-term glucocorticoids despite previous work suggesting they increase MACE in a dose-dependent way,” said Dr. Wallace, assistant professor of medicine at the University of Michigan, Ann Arbor, and a rheumatologist at the VA Ann Arbor Healthcare Center. “Our group previously presented work suggesting that less than 14 days of glucocorticoid use in a 6-month period is associated with a two-thirds increase in odds of MACE over the following 6 months, with 90 days of use associated with more than twofold increase.”

In recent years, researchers such as Dr. Wallace have focused attention on the risks of GCs in RA. The American College of Rheumatology and the European Alliance of Associations for Rheumatology emphasize avoiding long-term use of GCs in RA and keeping doses as small and over the shortest amount of time as possible.

When Dr. Wallace and colleagues looked at the clinical pattern of GC use for patients with RA during the past 2 years, those who took 5 mg, 7.5 mg, and 10 mg daily doses for 30 days and had stopped at least a year before had risk for MACE that rose significantly by 3%, 5%, and 7%, respectively, compared with those who didn’t take GCs in the past 2 years.

While those increases were small, risk for MACE rose even more for those who took the same daily doses for 90 days, increasing 10%, 15%, and 21%, respectively. Researchers linked current ongoing use of GCs for the past 90 days to a 13%, 19%, and 27% higher risk for MACE at those respective doses.

The findings “add to the literature suggesting that there is some risk even with low-dose steroids,” said Michael George, MD, assistant professor of rheumatology and epidemiology at the University of Pennsylvania, Philadelphia, who did not take part in the research but is familiar with the findings.

“We can see that even glucocorticoids taken several years ago may affect cardiovascular risk but that recent use has a bigger effect on risk,” Dr. George said in an interview. “This study also suggests that very low-dose use affects risk.”

For the new study, Dr. Wallace and colleagues examined a Veterans Affairs database and identified 18,882 patients with RA (mean age, 62.5 years; 84% male; 66% GC users) who met the criteria of being > 40 and < 90 years old. The subjects had an initial VA rheumatology visit during 2010-2018 and were excluded if they had a non-RA rheumatologic disorder, prior MACE, or heart failure. MACE was defined as MI, stroke/TIA, cardiac arrest, coronary revascularization, or death from CV cause.

A total of 16% of the cohort had the largest exposure to GCs, defined as use for 90 days or more; 23% had exposure of 14-89 days, and 14% had exposure of 1-13 days.

The median 5-year MACE risk at baseline was 5.3%, and 3,754 patients (19.9%) had high baseline MACE risk. Incident MACE occurred in 4.1% of patients, and the median time to MACE was 2.67 years (interquartile ratio, 1.26-4.45 years).

Covariates included factors such as age, race, sex, body mass index, smoking status, adjusted Elixhauser index, VA risk score for cardiovascular disease, cancer, hospitalization for infection, number of rheumatology clinic visits, and use of lipid-lowering drugs, opioids, methotrexate, biologics, and hydroxychloroquine.

Dr. Wallace noted limitations including the possibility of residual confounding and the influence of background cardiovascular risk. The study didn’t examine the clinical value of taking GCs or compare that to the potential risk. Nor did it examine cost or the risks and benefits of alternative therapeutic options.

A study released earlier this year suggested that patients taking daily prednisolone doses under 5 mg do not have a higher risk of MACE. Previous studies had reached conflicting results.

“Glucocorticoids can provide major benefits to patients, but these benefits must be balanced with the potential risks,” Dr. George said. At low doses, these risks may be small, but they are present. In many cases, escalating DMARD [disease-modifying antirheumatic drug] therapy may be safer than continuing glucocorticoids.”

He added that the risks of GCs may be especially high in older patients and in those who have cardiovascular risk factors: “Often biologics are avoided in these higher-risk patients. But in fact, in many cases biologics may be the safer choice.”

No study funding was reported. Dr. Wallace reported no relevant financial relationships, and some of the other authors reported various ties with industry. Dr. George reported research funding from GlaxoSmithKline and Janssen and consulting fees from AbbVie.

The American College of Rheumatology and the European Alliance of Associations for Rheumatology emphasize avoiding long-term use of GCs in RA and keeping doses as small and over the shortest amount of time as possible.

When Dr. Wallace and colleagues looked at the clinical pattern of GC use for patients with RA during the past 2 years, those who took 5 mg, 7.5 mg, and 10 mg daily doses for 30 days and had stopped at least a year before had risk for MACE that rose significantly by 3%, 5%, and 7%, respectively, compared with those who didn’t take GCs in the past 2 years.

While those increases were small, risk for MACE rose even more for those who took the same daily doses for 90 days, increasing 10%, 15%, and 21%, respectively. Researchers linked current ongoing use of GCs for the past 90 days to a 13%, 19%, and 27% higher risk for MACE at those respective doses.

The findings “add to the literature suggesting that there is some risk even with low-dose steroids,” said Michael George, MD, assistant professor of rheumatology and epidemiology at the University of Pennsylvania, Philadelphia, who did not take part in the research but is familiar with the findings.

“We can see that even glucocorticoids taken several years ago may affect cardiovascular risk but that recent use has a bigger effect on risk,” Dr. George said in an interview. “This study also suggests that very low-dose use affects risk.”

For the new study, Dr. Wallace and colleagues examined a Veterans Affairs database and identified 18,882 patients with RA (mean age, 62.5 years; 84% male; 66% GC users) who met the criteria of being > 40 and < 90 years old. The subjects had an initial VA rheumatology visit during 2010-2018 and were excluded if they had a non-RA rheumatologic disorder, prior MACE, or heart failure. MACE was defined as MI, stroke/TIA, cardiac arrest, coronary revascularization, or death from CV cause.

A total of 16% of the cohort had the largest exposure to GCs, defined as use for 90 days or more; 23% had exposure of 14-89 days, and 14% had exposure of 1-13 days.

The median 5-year MACE risk at baseline was 5.3%, and 3,754 patients (19.9%) had high baseline MACE risk. Incident MACE occurred in 4.1% of patients, and the median time to MACE was 2.67 years (interquartile ratio, 1.26-4.45 years).

Covariates included factors such as age, race, sex, body mass index, smoking status, adjusted Elixhauser index, VA risk score for cardiovascular disease, cancer, hospitalization for infection, number of rheumatology clinic visits, and use of lipid-lowering drugs, opioids, methotrexate, biologics, and hydroxychloroquine.

Dr. Wallace noted limitations including the possibility of residual confounding and the influence of background cardiovascular risk. The study didn’t examine the clinical value of taking GCs or compare that to the potential risk. Nor did it examine cost or the risks and benefits of alternative therapeutic options.

A study released earlier this year suggested that patients taking daily prednisolone doses under 5 mg do not have a higher risk of MACE. Previous studies had reached conflicting results.

“Glucocorticoids can provide major benefits to patients, but these benefits must be balanced with the potential risks,” Dr. George said. At low doses, these risks may be small, but they are present. In many cases, escalating DMARD [disease-modifying antirheumatic drug] therapy may be safer than continuing glucocorticoids.”

He added that the risks of GCs may be especially high in older patients and in those who have cardiovascular risk factors: “Often biologics are avoided in these higher-risk patients. But in fact, in many cases biologics may be the safer choice.”

No study funding was reported. Dr. Wallace reported no relevant financial relationships, and some of the other authors reported various ties with industry. Dr. George reported research funding from GlaxoSmithKline and Janssen and consulting fees from AbbVie.

SAN DIEGO – Even when taken at low doses and over short periods, glucocorticoids (GCs) were linked to a higher risk of major adverse cardiovascular events (MACE) over the long term in a Veterans Affairs population of older, mostly male patients with rheumatoid arthritis, a new retrospective cohort study has found.

The analysis of nearly 19,000 patients, presented by rheumatologist Beth Wallace, MD, MSc, at the annual meeting of the American College of Rheumatology, showed that the level of risk for MACE rose with the dose, duration, and recency of GC use, in which risk increased significantly at prednisone-equivalent doses as low as 5 mg/day, durations as short as 30 days, and with last use as long as 1 year before MACE.

Changes may be in store for how physicians do business based on pending proposals from the Federal Trade Commission to ban noncompete clauses and monitor potential merger monopolies.

In January 2023, the FTC announced a rule that would ban noncompete clauses, stating that such clauses reduce workers’ wages and stifle new businesses. Simply put, the rule would ban employers from entering into noncompete clauses with workers, including independent contractors.

Aspects of the rule include whether it should pertain to franchisees, whether senior executives should be exempted, and whether low-wage and high-wage workers should be treated differently.

According to the FTC, banning noncompete clauses would increase workers’ earnings by approximately $300 billion per year, save consumers as much as $148 billion in health care costs, and double the number of companies founded by former workers in the same field.

In June 2023, the FTC and the Department of Justice proposed changes to rules governing mergers, including changes to prenotification forms that would promote more efficient screening of potential mergers. According to a press release from the FTC, the proposed changes include provision of details about investments or corporate relationships, product and services, projected revenue streams, and previous acquisitions.

The proposal also includes a waiting period during which agencies would assess the risk that a merger would lessen competition or tend to create a monopoly.
 

What the FTC proposals mean for physicians

FTC Chair Lina M. Khan addressed attendees at the American College of Physicians at their annual meeting in October.

In March 2023, ACEP wrote to Ms. Khan in support of the banning of noncompete clauses. The ACEP also stated that the FTC should monitor the effect of a ban on the ability to recruit and maintain a stable physician workforce in rural and underserved areas “and should examine the potential impacts should nonprofit health systems be exempt from a ban.”

However, the American Medical Group Association, a nonprofit trade organization that supports multispecialty medical groups, opposes the ban. In a press release issued in March 2023, AMGA noted that, “As employers, AMGA members rely in part on noncompete agreements to build strong, sustainable care teams that work together to coordinate care for their patients. These care teams emphasize the importance of the doctor-patient relationship, which reasonable noncompete agreements help support.”

The American Medical Association supports the ban on noncompete clauses, detailed in an official AMA policy statement as, “support[ing] policies, regulations, and legislation that prohibits covenants not-to-compete for all physicians in clinical practice who hold employment contracts with for-profit or nonprofit hospital, hospital system, or staffing company employers.”

In regard to the merger guidelines, ACEP wrote a separate letter to Ms. Khan identifying some of the unique aspects of emergency medicine practice. The ACEP stressed the need for caution as the consolidation of medical practices continues, many under the umbrella of private equity investment companies.

“Unchecked mergers that substantially lessen competition in the labor market for emergency physicians, in which the employer is the buyer and the physician is the seller, can impact physicians directly by lowering wages or slowing wage growth, worsening benefits or working conditions, or contributing to other degradations in workplace quality,” according to ACEP.

The AMA also supports the FTC’s draft merger guidelines as protective of physicians and their working environments.

In September 2023, the AMA sent a letter to the FTC commending the agency on the proposed guidelines: “It is our strong contention that the agencies must have merger guidelines that protect physicians against health insurer mergers that may substantially lessen competition for the purchase of physician services and that degrade physician working conditions,” according to the AMA letter.

According the FTC, the proposed changes represent an expansion and reorganization of information along with the addition of new document requirements and represents the first comprehensive review of the Hart-Scott-Rodino Antitrust Improvements Act since 1978.

After soliciting public comments, the FTC is reviewing the proposals, and no specific date for a final vote has been announced.

More specifics on the potential changes to premerger notification, reporting, and waiting period requirements are available on the FTC website.

New research strengthens the body of evidence demonstrating an increased risk of blood cancer from exposure to low doses of radiation from CT scans. The results suggest that, for every 10,000 children examined with an average low dose of 8 mGy, 1-2 will likely develop a hematologic malignancy related to radiation exposure over the next 12 years.

The findings, published online in Nature Medicine, are based on more than 1.3 million CT scans in nearly 900,000 people younger than 22 years old when scanned.

This study makes a “significant contribution to the understanding of the effects of ionizing radiation, specifically x-rays, on the human body at the levels of radiation exposure encountered in diagnostic CT procedures,” Peter Marsden, PhD, and Jim Thurston, radiation protection experts at Dorset County (England) Hospital, NHS Foundation Trust, said in a press release from the U.K. nonprofit Science Media Centre.

These findings highlight levels of risk that “align with those currently estimated and do not suggest that the use of CT carries a greater risk than previously thought,” Dr. Marsden and Thurston said.

Exposure to moderate- (≥ 100 mGy) to high-dose (≥ 1 Gy) ionizing radiation is a well-established risk factor for leukemia in both children and adults. However, the risk associated with low-dose exposure (< 100 mGy) typically associated with diagnostic CT exams in children and teens remains unclear.

The current study, coordinated by the International Agency for Research on Cancer, aimed to improve direct estimates of cancer risk from low-dose radiation exposure from CT scans performed in childhood and adolescence. The researchers estimated radiation doses to the active bone marrow based on body part scanned, patient characteristics, time period, and inferred CT technical parameters.

A total of 790 hematologic malignancies, including lymphoid and myeloid malignancies, were identified during follow-up. More than half (51%) of the cases were diagnosed in people under age 20 and 88.5% were diagnosed in people under age 30 years.

Overall, the observational study found a nearly twofold excess risk of all hematologic malignancies per 100 mGy in children, adolescents, and young adults, with similar risk estimates observed for lymphoid and myeloid cancers. The excess relative risk for hematologic malignancies increased as the number of CT exams increased – with risk rising by 43% per exam.

The results of this study “strengthen the findings from previous low-dose studies of a consistent and robust dose-related increased risk of radiation-induced hematological malignancies” and highlight the importance of optimizing doses in this patient population, study author Elisabeth Cardis, PhD, with the Barcelona Institute for Global Health, and colleagues concluded.

Sarah McQuaid, PhD, chair of the nuclear medicine special interest group, Institute of Physics and Engineering in Medicine, York, England, agreed.

“This publication indicates that there could be a small cancer risk from CT scans in young people, but it is important for this to be viewed in the context of the substantial benefit these scans bring, due to the important diagnostic information they provide,” Dr. McQuaid said in the press release. Overall, “the number of patients whose medical care will have been improved from these CT scans will have been very high, and lives undoubtedly saved as a result.”

The study had no commercial funding. The authors and outside experts reported no relevant financial relationships.

Here is how old I am: When I graduated from medical school in 1977, marketing was prohibited. It was the legal profession that challenged the ban on advertising by professionals, leading to a landmark Supreme Court decision (Bates v State Bar of Arizona, 1977), which opened the door to marketing in the legal and medical professions.

Since then, marketing has become a critical component of growing, sustaining, and supporting private medical practices. Strategies range from the basic Internet website through postings on the major social media sites, and occasionally to larger-budget campaigns involving local radio, television, or billboard advertising.

All these methods are effective, to varying degrees; but nothing provides as much benefit – relative to its comparatively low cost – as the original marketing tool, word-of-mouth patient referrals. According to one survey, a clear majority of Americans still consider word-of-mouth recommendations to be the most influential element driving purchase decisions. Of course, some of your new patients already come from such referrals; but you can get a lot more by actively encouraging your existing patients to sing your praises, rather than waiting for them to do it on their own.

Soliciting current patients for referrals does take a little planning, structure, and a basic understanding of exactly how patient referral programs work. When executed correctly, a patient referral program can add substantial growth to your practice at minimal cost.

Your first step, as with any new project, should be to identify your goals: Clearly define what kind of patients you are looking to attract. Do you want more patients for cosmetic procedures, medical treatment, skin cancer screenings, a specific diagnosis (such as psoriasis), or a general mix? Design your announcements, brochures, and other literature (more on that in a minute) with those goals in mind.

Next, identify any applicable federal or state laws that dictate what you can and cannot legally do to encourage such referrals. It might be tempting, for example, to offer discounts on future services for successful referrals; but some medical groups frown on it, some states prohibit it, and the Federal Anti-Kickback Statute makes it illegal to pay anyone to refer Medicare or Medicaid patients to you if you file a claim for your services. In my experience, most patients are happy to recommend someone whom they believe provides excellent care to a friend or relative without any sort of monetary incentive; but if you plan to offer a material reward of any kind, run it by your attorney first.

Once your legal ducks are in order, make patients aware that you are accepting new patients and would welcome referrals by posting notices to that effect around your office and on your website and social media pages. Outline exactly what sort of patients (based on your goals, above) you are looking for, how to refer someone, whom to contact, and what kind of information is needed. Make it clear why existing patients should refer someone to your practice. Remind them of your specialized training, advanced technology, and patient-focused approach to health care. Highlight the benefits of the program and encourage your patients to participate.

Before implementation, you will need to educate your employees about the referral program and its benefits. All staff members should understand the program and be able to answer basic questions about it from patients or referring professionals. Encourage staffers to actively promote the program during patient interactions.

Then, start making some decisions. How, specifically, will you be requesting referrals in the office? Many physicians are not comfortable asking patients themselves. If you are going to let your assistants or receptionists do it, you will need to write a script for them to follow. An example of a basic script might be, “If you are happy with the care you are receiving here, we would love for you to tell your friends and family about us.” Your staff can then hand out cards, brochures, or both to reinforce the message, and perhaps send a follow-up email to remind them.

A referral system isn’t worth the effort if you don’t know whether it is working. Establish a system to track and monitor referrals. This could be as simple as a spreadsheet or purchasing a more sophisticated software program. Ensure that you can accurately identify and credit the referring patients for their referrals.

Make sure to thank referring patients with a thank-you note or email. Expressing gratitude will encourage continued participation in the program.

A successful referral program does not happen overnight. It relies on providing exceptional patient care and building strong relationships with your existing patients. By implementing such a program, you can leverage the satisfaction and loyalty of your patients to attract new patients and grow your private practice.

Here is how old I am: When I graduated from medical school in 1977, marketing was prohibited. It was the legal profession that challenged the ban on advertising by professionals, leading to a landmark Supreme Court decision (Bates v State Bar of Arizona, 1977), which opened the door to marketing in the legal and medical professions.

Since then, marketing has become a critical component of growing, sustaining, and supporting private medical practices. Strategies range from the basic Internet website through postings on the major social media sites, and occasionally to larger-budget campaigns involving local radio, television, or billboard advertising.

All these methods are effective, to varying degrees; but nothing provides as much benefit – relative to its comparatively low cost – as the original marketing tool, word-of-mouth patient referrals. According to one survey, a clear majority of Americans still consider word-of-mouth recommendations to be the most influential element driving purchase decisions. Of course, some of your new patients already come from such referrals; but you can get a lot more by actively encouraging your existing patients to sing your praises, rather than waiting for them to do it on their own.

Soliciting current patients for referrals does take a little planning, structure, and a basic understanding of exactly how patient referral programs work. When executed correctly, a patient referral program can add substantial growth to your practice at minimal cost.

Your first step, as with any new project, should be to identify your goals: Clearly define what kind of patients you are looking to attract. Do you want more patients for cosmetic procedures, medical treatment, skin cancer screenings, a specific diagnosis (such as psoriasis), or a general mix? Design your announcements, brochures, and other literature (more on that in a minute) with those goals in mind.

Next, identify any applicable federal or state laws that dictate what you can and cannot legally do to encourage such referrals. It might be tempting, for example, to offer discounts on future services for successful referrals; but some medical groups frown on it, some states prohibit it, and the Federal Anti-Kickback Statute makes it illegal to pay anyone to refer Medicare or Medicaid patients to you if you file a claim for your services. In my experience, most patients are happy to recommend someone whom they believe provides excellent care to a friend or relative without any sort of monetary incentive; but if you plan to offer a material reward of any kind, run it by your attorney first.

Once your legal ducks are in order, make patients aware that you are accepting new patients and would welcome referrals by posting notices to that effect around your office and on your website and social media pages. Outline exactly what sort of patients (based on your goals, above) you are looking for, how to refer someone, whom to contact, and what kind of information is needed. Make it clear why existing patients should refer someone to your practice. Remind them of your specialized training, advanced technology, and patient-focused approach to health care. Highlight the benefits of the program and encourage your patients to participate.

Before implementation, you will need to educate your employees about the referral program and its benefits. All staff members should understand the program and be able to answer basic questions about it from patients or referring professionals. Encourage staffers to actively promote the program during patient interactions.

Artificial intelligence can distinguish overlapping inflammatory conditions with total accuracy, according to a new study presented at the annual meeting of the American College of Rheumatology.

Texas pediatricians faced a conundrum during the pandemic. Endemic typhus, a flea-borne tropical infection common to the region, is nearly indistinguishable from multisystem inflammatory syndrome in children (MIS-C), a rare condition set in motion by SARS-CoV-2 infection. Children with either ailment had seemingly identical symptoms: fever, rash, gastrointestinal issues, and in need of swift treatment. A diagnosis of endemic typhus can take 4-6 days to confirm.

Tiphanie Vogel, MD, PhD, a pediatric rheumatologist at Texas Children’s Hospital, Houston, and colleagues sought to create a tool to hasten diagnosis and, ideally, treatment. To do so, they incorporated machine learning and clinical factors available within the first 6 hours of the onset of symptoms.

The team analyzed 49 demographic, clinical, and laboratory measures from the medical records of 133 children with MIS-C and 87 with endemic typhus. Using deep learning, they narrowed the model to 30 essential features that became the backbone of AI-MET, a two-phase clinical-decision support system.

Phase 1 uses 17 clinical factors and can be performed on paper. If a patient’s score in phase 1 is not determinative, clinicians proceed to phase 2, which uses an additional 13 weighted factors and machine learning.

In testing, the two-part tool classified each of the 220 test patients perfectly. And it diagnosed a second group of 111 patients with MIS-C with 99% (110/111) accuracy.

Of note, “that first step classifies [a patient] correctly half of the time,” Dr. Vogel said, so the second, AI phase of the tool was necessary for only half of cases. Dr. Vogel said that’s a good sign; it means that the tool is useful in settings where AI may not always be feasible, like in a busy ED.

Melissa Mizesko, MD, a pediatric rheumatologist at Driscoll Children’s Hospital in Corpus Christi, Tex., said that the new tool could help clinicians streamline care. When cases of MIS-C peaked in Texas, clinicians often would start sick children on doxycycline and treat for MIS-C at the same time, then wait to see whether the antibiotic brought the fever down.

“This [new tool] is helpful if you live in a part of the country that has typhus,” said Jane Burns, MD, director of the Kawasaki Disease Research Center at the University of California, San Diego, who helped develop a similar AI-based tool to distinguish MIS-C from Kawasaki disease. But she encouraged the researchers to expand their testing to include other conditions. Although the AI model Dr. Vogel’s group developed can pinpoint MIS-C or endemic typhus, what if a child has neither condition? “It’s not often you’re dealing with a diagnosis between just two specific diseases,” Dr. Burns said.

Dr. Vogel is also interested in making AI-MET more efficient. “This go-round we prioritized perfect accuracy,” she said. But 30 clinical factors, with 17 of them recorded and calculated by hand, is a lot. “Could we still get this to be very accurate, maybe not perfect, with less inputs?”

In addition to refining AI-MET, which Texas Children’s eventually hopes to make available to other institutions, Dr. Vogel and associates are also considering other use cases for AI. Lupus is one option. “Maybe with machine learning we could identify clues at diagnosis that would help recommend targeted treatment,” she said

Dr. Vogel disclosed potential conflicts of interest with Moderna, Novartis, Pfizer, and SOBI. Dr. Burns and Dr. Mizesko disclosed no relevant conflicts of interest.
