Oh, insurance claim denials. When patient care or treatment is warranted by a specific diagnosis, I wish insurers would just reimburse it without any hassle. That’s not reality. Let’s talk about insurance claim denials, how they’re rising and harming patient care, and what we can do about it. That’s kind of complicated.

Rising Trend in Claim Denials and Financial Impact

First, denials are increasing. Experian Health surveyed provider revenue cycle leaders— that’s a fancy term for people who manage billing and insurance claims — and 75% said that denials are increasing. This is up from 42% a few years ago. Those surveyed also said that reimbursement times and errors in claims are also increasing, and changes in policy are happening more frequently. This all adds to the problem. 

Aside from being time-consuming and annoying, claim denials take a toll on hospitals and patients. One analysis, which made headlines everywhere, showed that hospitals and health systems spent nearly $20 billion in 2022 trying to repeal overturned claims. This analysis was done by Premier, a health insurance performance company.

 

Breakdown of Denial Rates and Costs

Let’s do some quick whiteboard math. Health insurance companies get about 3 billion claims per year. According to surveys, about 15% of those claims are denied, so that leaves us with 450 million denied claims. Hospitals spend, on average, $43.84 per denied claim in administrative fees trying to get them overturned.

That’s about $19.7 billion spent on claim denials. Here’s the gut punch: Around 54% of those claims are ultimately paid, so that leaves us with $10.7 billion that we definitely should have saved. 

 

Common Reasons for Denials

Let’s take a look at major causes and what’s going on. 

Insurance denial rates are all over the place. It depends on state and plan. According to one analysis, the average for in-network claim denials across some states was 4% to 5%. It was 40% in Mississippi. According to HealthCare.gov, in 2021, around 17% of in-network claims were denied. 

The most common reasons were excluded services, a lack of referral or preauthorization, or a medical treatment not being deemed necessary. Then there’s the black box of “other,” just some arbitrary reason to make a claim denial. 

Many times, these denials are done by an algorithm, not by individual people. 

What’s more, a Kaiser Family Foundation analysis found that private insurers, including Medicare Advantage plans, were more likely to deny claims than public options. 

When broken down, the problem was higher among employer-sponsored and marketplace insurance, and less so with Medicare and Medicaid. 

 

Impact on Patient Care

Many consumers don’t truly understand what their health insurance covers and what’s going to be out of pocket, and many people don’t know that they have appeal rights. They don’t know who to call for help either. 

The ACA set up Consumer Assistance Programs (CAPs), which are designed to help people navigate health insurance problems. By law, private insurers have to share data with CAPs. Yet, only 3% of people who had trouble with health insurance claims called a CAP for help.

We all know some of the downstream effects of this problem. Patients may skip or delay treatments if they can’t get insurance to cover it or it’s too expensive. When post-acute care, such as transfer to a skilled nursing facility or rehab center, isn’t covered and we’re trying to discharge patients from the hospital, hospital stays become lengthened, which means they’re more expensive, and this comes with its own set of complications.

 

How Can We Address This?

I’m genuinely curious about what you all have done to efficiently address this problem. I’m looking at this publication from the American Health Information Management Association about major reasons for denial. We’ve already talked about a lack of preauthorization or procedures not being covered, but there are also reasons such as missing or incorrect information, duplicate claims, and not filing within the appropriate time.

Also, if treatments or procedures are bundled, they can’t be filed separately. 

Preventing all of this would take a large effort. Healthcare systems would have to have a dedicated team, who would understand all the major reasons for denials, identify common patterns, and then fill everything out with accurate information, with referrals, with preauthorizations, high-specificity codes, and the correct modifiers — and do all of this within the filing deadline every time. 

You would need physicians on board, but also people from IT, finance, compliance, case management, registration, and probably a bunch of other people who are already stretched too thin. 

Perhaps our government can do more to hold insurers accountable and make sure plans, such as Medicare Advantage, are holding up their end of the public health bargain.

It’s an uphill $20 billion battle, but I’m optimistic. What about you? What’s your unfiltered take on claim denials? What more can we be doing?

TOPLINE:

Oral doxycycline (200 mg twice daily for 28 days) appears to be as effective as intravenous (IV) penicillin for the treatment of ocular syphilis for some patients with the condition.

METHODOLOGY:

• Researchers conducted a retrospective cohort study of ocular syphilis cases diagnosed from 2017 to 2023 in Los Angeles, analyzing 32 patients with a median age of 46 years (78% men).
• Patients treated before January 2022 received IV doxycycline, while those treated after that date were given the option to receive an oral form of the drug.
• A total of 16 patients received oral doxycycline (seven patients received only oral doxycycline; nine received a short course of parenteral penicillin followed by a full course of oral doxycycline); another 16 patients received a full course of IV penicillin.
• The analysis measured visual acuity (VA), ocular inflammation, and rapid plasma reagin (RPR).

TAKEAWAY:

• The doxycycline group had better median VA at both the initial presentation and the final follow-up than the penicillin group (VA, 0.44, 0.18; P = .04; VA, 1.0, 0.40; P = .03, respectively).
• Resolution of ocular inflammation showed no significant differences between the doxycycline and IV penicillin groups (P = .62 for both).
• All patients who had follow-up at 9 months demonstrated a fourfold decrease in RPR titers (four people in the oral doxycycline group and seven people in the IV penicillin group).

IN PRACTICE:

“We found that oral doxycycline for the treatment of ocular syphilis may be safe and effective in a selected subset of patients who completed an extended oral antibiotic regimen,” the study authors wrote. “Other studies have also demonstrated similar efficacy of oral therapy when compared with IV therapy. A fourfold decrease in RPR titers was considered an adequate serologic treatment response and corresponds with resolution of syphilis disease activity. This was observed in all patients with more than 9 months of follow-up. Long-term monitoring is recommended for those treated with doxycycline to ensure clinical and serologic response.”

SOURCE:

The study was led by Brian C. Toy, MD, of the Roski Eye Institute at the Keck School of Medicine at the University of Southern California in Los Angeles. It was published online in JAMA Network Open.

LIMITATIONS:

The study was retrospective in nature, used heterogeneous treatment methods, and lacked longitudinal RPR titers.

DISCLOSURES:

Toy served on physician advisory boards for Alimera, EyePoint, Bausch and Lomb, and Regeneron. No other disclosures were reported.

Long COVID can have an enormous impact on people’s ability to work, particularly if they do not have workplace accommodations and support. Although some patients experience symptoms so severe that they cannot work under any conditions, medical providers and employers can help ensure many patients with long COVID can stay in the workforce.

Long COVID is an infection-associated chronic condition that occurs after SARS-CoV-2 infection and is present for at least 3 months as a continuous, relapsing and remitting, or progressive disease state that affects one or more organ systems. By the end of 2023, at least 400 million people worldwide were estimated to have long COVID.

As members of the Patient-Led Research Collaborative, an international group of more than 60 researchers and health advocates living with long COVID and other infection-associated chronic conditions, we have published one of the first research studies of people with long COVID and their desire to work, the specific needs they have, and what doctors and employers can do to create a path for returning to the workforce. 

In our recent paper, we document the barriers and facilitators that individuals living with long COVID experience when attempting to return to work. Our recommendations are based on these findings and include recommendations for both medical providers and employers. 

If you are a medical provider:

• Ensure you adequately document your patients’ COVID cases, any long COVID diagnoses, and the functional impairment that long COVID causes. Remember that you can diagnose a patient with long COVID on the basis of their symptoms, and clinical guidelines do not require a record of a positive COVID-19 test, which many patients lack owing to testing barriers.
• Keep up to date on research on long COVID and related infection-associated chronic conditions — for example, through the Project ECHO Long COVID and Fatiguing Illness Recovery Program — and learn about pacing and other treatment options.

If you are an employer: 

• Utilize a return-to-work model in which any worker with suspected or confirmed COVID discusses support they may need with their employer when they return to work, with additional check-in dates scheduled to reevaluate supports as needed. Planning for this collaborative and iterative evaluation of return-to-work supports for all workers with COVID-19 is important because it may not be immediately clear to a worker whether they have developed long COVID or are generally recuperating from the illness.
• Do not require medical documentation of a SARS-CoV-2 infection or a Long COVID diagnosis to access accommodations — this is owing to disparities in accessing documentation.
• Tailor job responsibilities, provide remote options, allow flexible hours, and provide longer-range deadlines to account for symptoms for people with long COVID and other infection-associated chronic conditions.
• Provide accommodations to any caregivers of people with long COVID in your workplace.
• If requiring in-person work, make the workplace as safe as possible through ventilation and masking requirements, which will help ensure fewer of your workers develop long COVID, and those already with infection-associated chronic conditions will not get worse.

Our findings and recommendations are specific to long COVID, but they can and should apply to other disabilities. Given that our study’s sample was predominately White and working in jobs that did not require substantial physical labor, additional recommendations may be needed for other populations and workers who have labor-intensive jobs.

 

510 Study Participants

Long COVID is characterized as a relapsing-remitting illness, often described as episodic, in which an individual’s symptoms may fluctuate. Symptoms can become more or less severe depending on tasks, exertion, and social support in addition to physiologic processes and medical intervention. In our paper, we illustrate how the long COVID return-to-work experience and individuals’ symptoms can be shaped by workplace, home, and medical environments. 

We randomly selected 510 participants from a global survey of people living with long COVID and systematically analyzed their open-ended responses using established qualitative analysis methods. In this study, we specifically analyzed what patients wrote about their return-to-work experiences, considering how work experiences and relapsing and remitting long COVID symptoms intersected with personal lives and medical care. 

Most of the study participants identified as White, were 30-60 years old (ie, in their key earning years), and had at least a baccalaureate degree. Participants lived in the United States (38%), United Kingdom (25%), continental Europe (8%), Canada (4%), or other countries (25%). Most participants worked in professions that did not require substantial physical labor, and individuals in those fields may experience even greater return-to-work barriers than are reported in this study.

 

Key Findings

Through our qualitative analysis, we identified four primary return-to-work themes: 

1. People living with long COVID have a strong desire and financial need to return to work. 

The participants in our study described how they had experienced financial hardship because they could not successfully return to work and may have incurred new expenses with long COVID. They also often wrote how they wanted to return to work because their jobs provided meaning and structure for their lives. Some people in this study shared how they had tried to return to their jobs but relapsed. As a result, they considered leaving the workforce.

2. Workers’ long COVID symptoms intersect with organization of work and home life.

Most of the people in our study were employed in positions that did not require substantial physical labor. Even so, workers described how their long COVID symptoms were exacerbated by some job tasks. Computer screen time; reading dense material or writing (including emails); and conversations and meetings, regardless of whether they were in-person or via phone or video conferencing, could trigger or make symptoms worse. Workers who needed to stand for long periods of time, such as teachers and healthcare workers, and workers who needed to do lifting as part of their jobs described how these requirements were too taxing and could lead to relapses.

Because of the relapsing and remitting nature of many long COVID symptoms, people reported how it could be difficult to predict how job tasks, long hours, or pressing deadlines may exacerbate symptoms, which would require them to take time off work. For these participants, “pushing through” symptoms only made the symptoms worse. However, people in the study who were allowed to work from home reported how pacing, elevating their legs, and conserving energy (especially by not commuting) was key to doing their jobs well.

Some people in the study described how they were only able to return to work because they had substantial support from family or partners at home. These individuals shared how the people they lived with did most of the cooking, cleaning, and other household tasks so that the person living with long COVID could conserve their energy for work. This reorganization of home life notably shifted household tasks and caregiving to other people in the household, but without this shift, the individual’s long COVID symptoms may be too severe to work.

3. People with long COVID experience disbelief and stigma at work and healthcare settings.

Some people in our study described how their colleagues, supervisors, and human resource managers insinuated that they were fabricating or exaggerating their symptoms. This made it hard for workers to communicate what support they needed and could limit access to necessary work accommodations.

Many people in our study also described how medical providers did not believe that they had long COVID despite experiencing debilitating symptoms, often because they did not have a positive COVID-19 test to prove they had had an acute infection. Many people with long COVID may not have a positive COVID-19 test because:

• They could not access a test because testing access was limited at the start of the COVID-19 pandemic, there are transportation and cost barriers to tests, many health insurance providers no longer cover tests; and there are fewer public testing sites since the World Health Organization declared an end to the public health emergency;
• There is a high probability of false-negative results for viral and antibody tests (especially during the first wave of the pandemic and for individuals with limited immune response); and
• People can develop long COVID after asymptomatic acute infection.

Although healthcare providers can provide a long COVID diagnosis without a positive COVID-19 test on the basis of a patient’s presentation of symptoms and clinical history, many people in our study said that their providers would not provide this diagnosis, which restricted access to worker’s compensation, paid time off, and job accommodations.

Many people in the study also reported that their medical providers misdiagnosed them with a mental health disorder, such as anxiety, instead of long COVID. Although some people with long COVID may experience poor mental health as a natural consequence of dealing with a debilitating medical condition or may have neuropsychiatric symptoms as part of their long COVID, long COVID is not caused by an underlying psychiatric illness.

4. Support of medical providers is key to successful return to work for people living with long COVID.

Some people in our study described how they were able to get workplace accommodations or access workers’ compensation or sick leave because their medical providers recognized they had long COVID and provided them with this documentation. Some of these participants did not have a positive COVID-19 test, but their medical providers were able to diagnose them with long COVID on the basis of symptom presentation and clinical history. This documentation was critical for helping workers remain financially stable and able to return to work.

 

Conclusion

While we continue to search for treatment and cures for long COVID and work to provide a robust social safety net, it is crucial to address the stigma, inaccessibility, and lack of support often experienced by patients in their workplaces. Disabled people have long faced these issues; long COVID may be an opportunity to revolutionize the workplace to ensure an inclusive and accessible environment that can improve the lives of all workers.

Long COVID can have an enormous impact on people’s ability to work, particularly if they do not have workplace accommodations and support. Although some patients experience symptoms so severe that they cannot work under any conditions, medical providers and employers can help ensure many patients with long COVID can stay in the workforce.

Long COVID is an infection-associated chronic condition that occurs after SARS-CoV-2 infection and is present for at least 3 months as a continuous, relapsing and remitting, or progressive disease state that affects one or more organ systems. By the end of 2023, at least 400 million people worldwide were estimated to have long COVID.

As members of the Patient-Led Research Collaborative, an international group of more than 60 researchers and health advocates living with long COVID and other infection-associated chronic conditions, we have published one of the first research studies of people with long COVID and their desire to work, the specific needs they have, and what doctors and employers can do to create a path for returning to the workforce. 

In our recent paper, we document the barriers and facilitators that individuals living with long COVID experience when attempting to return to work. Our recommendations are based on these findings and include recommendations for both medical providers and employers. 

If you are a medical provider:

• Ensure you adequately document your patients’ COVID cases, any long COVID diagnoses, and the functional impairment that long COVID causes. Remember that you can diagnose a patient with long COVID on the basis of their symptoms, and clinical guidelines do not require a record of a positive COVID-19 test, which many patients lack owing to testing barriers.
• Keep up to date on research on long COVID and related infection-associated chronic conditions — for example, through the Project ECHO Long COVID and Fatiguing Illness Recovery Program — and learn about pacing and other treatment options.

If you are an employer: 

• Utilize a return-to-work model in which any worker with suspected or confirmed COVID discusses support they may need with their employer when they return to work, with additional check-in dates scheduled to reevaluate supports as needed. Planning for this collaborative and iterative evaluation of return-to-work supports for all workers with COVID-19 is important because it may not be immediately clear to a worker whether they have developed long COVID or are generally recuperating from the illness.
• Do not require medical documentation of a SARS-CoV-2 infection or a Long COVID diagnosis to access accommodations — this is owing to disparities in accessing documentation.
• Tailor job responsibilities, provide remote options, allow flexible hours, and provide longer-range deadlines to account for symptoms for people with long COVID and other infection-associated chronic conditions.
• Provide accommodations to any caregivers of people with long COVID in your workplace.
• If requiring in-person work, make the workplace as safe as possible through ventilation and masking requirements, which will help ensure fewer of your workers develop long COVID, and those already with infection-associated chronic conditions will not get worse.

Our findings and recommendations are specific to long COVID, but they can and should apply to other disabilities. Given that our study’s sample was predominately White and working in jobs that did not require substantial physical labor, additional recommendations may be needed for other populations and workers who have labor-intensive jobs.

 

510 Study Participants

Long COVID is characterized as a relapsing-remitting illness, often described as episodic, in which an individual’s symptoms may fluctuate. Symptoms can become more or less severe depending on tasks, exertion, and social support in addition to physiologic processes and medical intervention. In our paper, we illustrate how the long COVID return-to-work experience and individuals’ symptoms can be shaped by workplace, home, and medical environments. 

We randomly selected 510 participants from a global survey of people living with long COVID and systematically analyzed their open-ended responses using established qualitative analysis methods. In this study, we specifically analyzed what patients wrote about their return-to-work experiences, considering how work experiences and relapsing and remitting long COVID symptoms intersected with personal lives and medical care. 

Most of the study participants identified as White, were 30-60 years old (ie, in their key earning years), and had at least a baccalaureate degree. Participants lived in the United States (38%), United Kingdom (25%), continental Europe (8%), Canada (4%), or other countries (25%). Most participants worked in professions that did not require substantial physical labor, and individuals in those fields may experience even greater return-to-work barriers than are reported in this study.

 

Key Findings

Through our qualitative analysis, we identified four primary return-to-work themes: 

1. People living with long COVID have a strong desire and financial need to return to work. 

The participants in our study described how they had experienced financial hardship because they could not successfully return to work and may have incurred new expenses with long COVID. They also often wrote how they wanted to return to work because their jobs provided meaning and structure for their lives. Some people in this study shared how they had tried to return to their jobs but relapsed. As a result, they considered leaving the workforce.

2. Workers’ long COVID symptoms intersect with organization of work and home life.

Most of the people in our study were employed in positions that did not require substantial physical labor. Even so, workers described how their long COVID symptoms were exacerbated by some job tasks. Computer screen time; reading dense material or writing (including emails); and conversations and meetings, regardless of whether they were in-person or via phone or video conferencing, could trigger or make symptoms worse. Workers who needed to stand for long periods of time, such as teachers and healthcare workers, and workers who needed to do lifting as part of their jobs described how these requirements were too taxing and could lead to relapses.

Because of the relapsing and remitting nature of many long COVID symptoms, people reported how it could be difficult to predict how job tasks, long hours, or pressing deadlines may exacerbate symptoms, which would require them to take time off work. For these participants, “pushing through” symptoms only made the symptoms worse. However, people in the study who were allowed to work from home reported how pacing, elevating their legs, and conserving energy (especially by not commuting) was key to doing their jobs well.

Some people in the study described how they were only able to return to work because they had substantial support from family or partners at home. These individuals shared how the people they lived with did most of the cooking, cleaning, and other household tasks so that the person living with long COVID could conserve their energy for work. This reorganization of home life notably shifted household tasks and caregiving to other people in the household, but without this shift, the individual’s long COVID symptoms may be too severe to work.

3. People with long COVID experience disbelief and stigma at work and healthcare settings.

Some people in our study described how their colleagues, supervisors, and human resource managers insinuated that they were fabricating or exaggerating their symptoms. This made it hard for workers to communicate what support they needed and could limit access to necessary work accommodations.

Many people in our study also described how medical providers did not believe that they had long COVID despite experiencing debilitating symptoms, often because they did not have a positive COVID-19 test to prove they had had an acute infection. Many people with long COVID may not have a positive COVID-19 test because:

• They could not access a test because testing access was limited at the start of the COVID-19 pandemic, there are transportation and cost barriers to tests, many health insurance providers no longer cover tests; and there are fewer public testing sites since the World Health Organization declared an end to the public health emergency;
• There is a high probability of false-negative results for viral and antibody tests (especially during the first wave of the pandemic and for individuals with limited immune response); and
• People can develop long COVID after asymptomatic acute infection.

Although healthcare providers can provide a long COVID diagnosis without a positive COVID-19 test on the basis of a patient’s presentation of symptoms and clinical history, many people in our study said that their providers would not provide this diagnosis, which restricted access to worker’s compensation, paid time off, and job accommodations.

Many people in the study also reported that their medical providers misdiagnosed them with a mental health disorder, such as anxiety, instead of long COVID. Although some people with long COVID may experience poor mental health as a natural consequence of dealing with a debilitating medical condition or may have neuropsychiatric symptoms as part of their long COVID, long COVID is not caused by an underlying psychiatric illness.

4. Support of medical providers is key to successful return to work for people living with long COVID.

Some people in our study described how they were able to get workplace accommodations or access workers’ compensation or sick leave because their medical providers recognized they had long COVID and provided them with this documentation. Some of these participants did not have a positive COVID-19 test, but their medical providers were able to diagnose them with long COVID on the basis of symptom presentation and clinical history. This documentation was critical for helping workers remain financially stable and able to return to work.

 

Conclusion

While we continue to search for treatment and cures for long COVID and work to provide a robust social safety net, it is crucial to address the stigma, inaccessibility, and lack of support often experienced by patients in their workplaces. Disabled people have long faced these issues; long COVID may be an opportunity to revolutionize the workplace to ensure an inclusive and accessible environment that can improve the lives of all workers.

An electronic nudge explaining the cardiovascular benefits of the influenza vaccine increased vaccination rates, particularly among people who had previously had a heart attack, showed the NUDGE FLU series of clinical trials.

Influenza has the potential to be a dangerous infection on its own, but it increases the risk for cardiovascular events among people with a history of heart attack, said the study’s lead author, Ankeet Bhatt, MD, a cardiologist at Kaiser Permanente San Francisco Medical Center, San Francisco.

“Yearly influenza vaccines help prevent influenza infection and, in patients with a heart attack, are potentially cardioprotective,” he said during his presentation at the American Heart Association (AHA) Scientific Sessions 2024 in Chicago. The NUDGE FLU results were simultaneously published online in JAMA Cardiology.

In Denmark, where the trials were conducted, about 80% of older adults get flu shots, but only about 40% of younger adults with chronic diseases do, Bhatt reported. In the United States, about 45% of adults and 55% of children received at least one dose of the flu vaccine in the 2023/24 flu season, according to the US Centers for Disease Control and Prevention (CDC).

 

The NUDGE FLU Trials

Bhatt and his colleagues conducted three related clinical trials during the 2022/23 and 2023/24 flu seasons: NUDGE-FLU and NUDGE-FLU-2 targeted older adults, whereas NUDGE-FLU-CHRONIC targeted younger adults with chronic diseases. Nearly 2 million people were involved in the three trials.

Participants were randomized to receive one of a series of different behavioral-science-informed letters, delivered through a government-run electronic communication system, or no reminder.

People who received any of the nudges had higher rates of vaccination; among heart attack survivors, there was a 1.8% improvement and among adults without a history of heart attack, there was a 1.3% improvement. But a nudge that explained the potential cardiovascular benefits of flu shots was even more effective, leading to a 3.9% increase among people with a history of heart attack and a 2% increase among those with no heart attack history.

“A simple sentence resulted in a durable improvement in the vaccination rate,” said Bhatt.

The effect was even greater among those who had not been vaccinated in the previous flu season. Among heart attack survivors, nearly 14% more people got the vaccine compared with just 1.5% more survivors who were previously vaccinated. And it was most effective among younger adults who had experienced a recent heart attack, resulting in a 26% increase.

“The impact was larger in patients with a history of acute myocardial infarction, in those who were vaccine-hesitant, and in younger people” — all groups with the most to gain from vaccination in terms of cardiovascular protection — Bhatt reported.

About 25% of people in the United States are unsure about whether to get a flu shot, said Orly Vardeny, PharmD, professor of medicine at the University of Minnesota Medical School in Minneapolis, who was not involved in the study. The fact that previously unvaccinated people were convinced by the nudges is reassuring. “That’s the group where this intervention is most likely to move the needle,” she said.

Around half of all people hospitalized for flu in the United States have cardiovascular disease, CDC data showed, so “even a small increase in the number of patients who get vaccinated has substantial public health benefits,” Vardeny said.

The NUDGE FLU series showed that nudges like this should be employed as a simple tool to improve vaccination rates, but the system would be much more difficult to implement in the United States, Bhatt said.

Denmark has a national health service and a preexisting government electronic communication system, whereas the US system is privately run and more fractured. It would be possible to make it work, he pointed out, but would take some effort.

Vaccines recommended by the Advisory Committee on Immunization Practices (ACIP) offer important protection against severe illness for pregnant people and their babies.¹ However, vaccination coverage estimates among pregnant people remain suboptimal.^2-5 Additionally, some measures indicate that vaccine hesitancy among pregnant people is increasing; for example, 17.5% of surveyed pregnant women reported being very hesitant about influenza vaccination during pregnancy in 2019-2020, compared with 24.7% in 2022-2023.⁶As fall and winter virus season continues, consider opportunities for you and your staff to help communicate the importance of prenatal vaccination to pregnant patients in your care. Explore updated provider toolkits and prenatal vaccination patient education resources, including fact sheets, social media assets, posters, and short videos on respiratory syncytial virus (RSV), Tdap, COVID-19, influenza, and hepatitis B.

In an interview, CDC’s Haben Debessai, MD, an adjunct instructor in obstetrics and gynecology at Emory School of Medicine, Atlanta, Georgia, contextualizes the data to help healthcare professionals communicate effectively with their pregnant patients. 

 

What can practitioners communicate to patients about why it is important to get vaccinated during their pregnancy?

When communicating with their patients, practitioners can consider opportunities to discuss how vaccines work during pregnancy, emphasizing that prenatal vaccinations are beneficial for both the pregnant person and the fetus. It can be helpful to educate patients on how a pregnant person’s immune system can develop antibodies that will then pass to the fetus during the pregnancy and confer protection during the infant’s early months of life — when they are highly susceptible to illnesses that can be severe, such as RSV-associated lower respiratory tract infections. It can also be useful to discuss pregnancy’s impact on the immune system, which contributes to pregnant people being at higher risk for severe illness from infections like COVID-19 and flu, if contracted. The outcomes of severe illness can be dire for both the pregnant person and their pregnancy, which is why vaccination is the best mitigation option. It can also be beneficial to share with patients that some vaccines, like RSV and Tdap, are specifically for neonatal benefit, which could help patients understand why some vaccines are recommended at a specific gestational age and in each pregnancy or subsequent pregnancies. 

What is known about pregnant populations that experience disparities in vaccination coverage? 

While vaccination coverage among pregnant people is suboptimal, coverage estimates are often lowest among Black pregnant people, some of whom report experiencing mistreatment and discrimination during pregnancy and delivery.⁷ It is important to recognize that there are many intersecting factors that may impact vaccination coverage. Systemic and structural factors may prohibit some patient populations from accessing vaccinations (eg, transportation barriers, difficulty accessing adequate healthcare for those on government assistance, language barriers). To be responsive to the intersectional lived realities of each of these communities, the medical and public health community continually strives to increase trustworthiness, which can lead to increased uptake of vaccinations in these populations. 

What vaccines are available and recommended for pregnant people?

Four vaccines are routinely recommended during pregnancy: Tdap, COVID-19, influenza (seasonal), and RSV (seasonal). CDC recommends getting a Tdap vaccine between the 27th and 36th week of each pregnancy, preferably during the earlier part of this time period. CDC recommends that everyone 6 months or older in the United States, including pregnant people, stay up to date on COVID-19 vaccines. A COVID-19 vaccine can be given during any trimester of pregnancy. CDC recommends an annual flu vaccine during each flu season (fall/winter) for everyone 6 months or older in the United States, including pregnant people. A flu vaccine can be given during any trimester of pregnancy. For individuals who will be between 32 and 36 weeks pregnant during September through January, CDC recommends getting an RSV vaccine. RSV season and timing of vaccination may vary depending on geography. If a pregnant patient does not get the RSV vaccine during their pregnancy, CDC recommends that their baby receive an RSV monoclonal antibody (nirsevimab) to provide additional protection during the infant’s first RSV season, if they are younger than 8 months. At this time, pregnant people who received an RSV vaccine during a previous pregnancy (last year) are not recommended to receive another RSV vaccine during pregnancy. The current recommendation is for babies born during subsequent pregnancies to receive nirsevimab. Some pregnant people may also need other vaccines, such as hepatitis B. 

How can practitioners approach conversations about vaccination during pregnancy amid increasing vaccine hesitancy?

Many pregnant people who do get vaccinated describe their provider’s recommendation as an important motivator toward vaccination.^8-11 Communications research suggests that practitioners can further increase trustworthiness by openly discussing potential side effects of prenatal vaccinations and providing patients with a rationale for why each vaccine is recommended. Practitioners can also utilize opportunities to communicate that the risk for severe illness from whooping cough, COVID-19, flu, and RSV in pregnancy and among neonates in the first few months of life is often higher than the risk for an adverse reaction from receiving ACIP-recommended vaccines. Finally, practitioners can consider sharing tested and refined patient education resources at least one appointment prior to the recommended administration of each vaccine, providing individuals with time to process the information they need to facilitate their vaccine decision-making process.

Some patients may be more comfortable with older, well-known prenatal vaccinations but have skepticism about newer vaccines like COVID-19 and RSV. How can practitioners respond to these concerns?

As pregnant people navigate the challenges of making health decisions that could impact their developing baby, practitioners can build trust through empathetically responding to safety concerns and questions, particularly with respect to newly authorized vaccines. Vaccine confidence may be strengthened by communicating to patients that all recommended vaccinations, including those that have been newly authorized, have been rigorously tested prior to being recommended for pregnant people. Additionally, in my clinical practice, I see that patients are often more comfortable accepting vaccines when the benefit for the baby is clearly communicated. I have been pleasantly surprised that most patients I have counseled on the new maternal RSV vaccine have been receptive, making statements like, “If this will help protect my baby from getting sick, then yes, I will get it.”

As you and your staff care for pregnant patients during fall and winter virus season, remember that a provider recommendation remains one of the strongest known predictors of vaccination uptake.¹² As a trusted source of information about prenatal vaccination, consider further incorporating patient education resources to help communicate how prenatal vaccination helps pregnant people share important protection against severe illnesses with their babies.

Vaccines recommended by the Advisory Committee on Immunization Practices (ACIP) offer important protection against severe illness for pregnant people and their babies.¹ However, vaccination coverage estimates among pregnant people remain suboptimal.^2-5 Additionally, some measures indicate that vaccine hesitancy among pregnant people is increasing; for example, 17.5% of surveyed pregnant women reported being very hesitant about influenza vaccination during pregnancy in 2019-2020, compared with 24.7% in 2022-2023.⁶As fall and winter virus season continues, consider opportunities for you and your staff to help communicate the importance of prenatal vaccination to pregnant patients in your care.

What can practitioners communicate to patients about why it is important to get vaccinated during their pregnancy?

When communicating with their patients, practitioners can consider opportunities to discuss how vaccines work during pregnancy, emphasizing that prenatal vaccinations are beneficial for both the pregnant person and the fetus. It can be helpful to educate patients on how a pregnant person’s immune system can develop antibodies that will then pass to the fetus during the pregnancy and confer protection during the infant’s early months of life — when they are highly susceptible to illnesses that can be severe, such as RSV-associated lower respiratory tract infections. It can also be useful to discuss pregnancy’s impact on the immune system, which contributes to pregnant people being at higher risk for severe illness from infections like COVID-19 and flu, if contracted. The outcomes of severe illness can be dire for both the pregnant person and their pregnancy, which is why vaccination is the best mitigation option. It can also be beneficial to share with patients that some vaccines, like RSV and Tdap, are specifically for neonatal benefit, which could help patients understand why some vaccines are recommended at a specific gestational age and in each pregnancy or subsequent pregnancies. 

What is known about pregnant populations that experience disparities in vaccination coverage? 

While vaccination coverage among pregnant people is suboptimal, coverage estimates are often lowest among Black pregnant people, some of whom report experiencing mistreatment and discrimination during pregnancy and delivery.⁷ It is important to recognize that there are many intersecting factors that may impact vaccination coverage. Systemic and structural factors may prohibit some patient populations from accessing vaccinations (eg, transportation barriers, difficulty accessing adequate healthcare for those on government assistance, language barriers). To be responsive to the intersectional lived realities of each of these communities, the medical and public health community continually strives to increase trustworthiness, which can lead to increased uptake of vaccinations in these populations. 

What vaccines are available and recommended for pregnant people?

Four vaccines are routinely recommended during pregnancy: Tdap, COVID-19, influenza (seasonal), and RSV (seasonal). CDC recommends getting a Tdap vaccine between the 27th and 36th week of each pregnancy, preferably during the earlier part of this time period. CDC recommends that everyone 6 months or older in the United States, including pregnant people, stay up to date on COVID-19 vaccines. A COVID-19 vaccine can be given during any trimester of pregnancy. CDC recommends an annual flu vaccine during each flu season (fall/winter) for everyone 6 months or older in the United States, including pregnant people. A flu vaccine can be given during any trimester of pregnancy. For individuals who will be between 32 and 36 weeks pregnant during September through January, CDC recommends getting an RSV vaccine. RSV season and timing of vaccination may vary depending on geography.

Ringworm (also known as tinea, jock itch, or athlete’s foot) is a common infection caused by dermatophyte fungi, known to affect skin, hair, or nails. It causes skin infections that are typically mild and are often treated with topical antifungals.

However, in recent years, newly emerging dermatophyte strains have been causing more severe and harder-to-treat ringworm. Notably, one emerging strain, Trichophyton mentagrophytes genotype VII(TMVII), is associated with sexual contact. In recent years, TMVII infections linked to sexual contact have been reported among men who have sex with men in Europe and in travelers returning from Southeast Asia. The first US case of TMVII was reported in June 2024, after which public health authorities were alerted to additional cases; all were associated with recent sexual contact. Other dermatophyte species have also been reported to cause ringworm transmitted through sexual contact. 

Here are some key points to know about sexually transmitted ringworm. 

Tell me more about sexually transmitted ringworm: What is causing it?

Skin-to-skin contact is a common mode of ringworm transmission. In recent years, transmission of ringworm via intimate or sexual contact has been increasingly recognized. However, clinicians may not immediately consider ringworm when evaluating genital, facial, or perianal lesions. Infections with sexually transmitted TMVII commonly cause lesions on anatomical sites that may be exposed during intimate or sexual contact, such as the face, genitals, and perianal region. Sexual transmission of TMVII has been reported in Europe, predominantly among men who have sex with men, for several years. Other dermatophyte strains have been reported in association with sexual contact, including the emerging strain Trichophyton indotineae. However, sexual transmission is not the main mode of transmission for T indotineae and other dermatophyte strains. 

When should clinicians suspect a potential case of sexually transmitted ringworm?

Providers should consider sexually transmitted ringworm when seeing ringworm in locations associated with intimate contact (for example, a rash on or around the genitals, perianal area, or mouth). 

The typical appearance of ringworm is a raised, ring-like, erythematous rash with a scaly border that grows over time. The rash may appear pink, brown, or gray on different types of skin. Patients may note itching and flaking of the rash. In areas with hair such as the beard area, ringworm can present as pustules and be associated with hair loss.

Emerging ringworm infections can present in atypical or more severe ways, including a highly inflammatory (painful, scarring, or otherwise severe) rash, a rash affecting a large area or multiple sites, nodules, and pustules. 

Sexually transmitted ringworm may be considered based on sexual history and recent sexual contact with someone with known TMVII. Recent history of travel to a region with reported sexually transmitted ringworm may increase suspicion of TMVII. In patients with a travel history to South Asia, T indotineae should be considered, especially if the rash does not improve with oral terbinafine. 

How can testing help guide the diagnosis of sexually transmitted ringworm infection?

When evaluating a rash that may represent ringworm, providers should use a confirmatory test such as potassium hydroxide (KOH) preparation when possible. KOH prep can confirm the presence of a fungus that causes ringworm, but it does not identify the species or type of ringworm. Testing such as fungal culture and molecular testing can help identify specific types of ringworm, but these tests are not often performed and may take a long time to yield results.

Routine fungal cultures cannot identify TMVII and T indotineae; these tests may identify the genus Trichophyton, but only advanced molecular testing, which is available at selected US laboratories, can identify TMVII and T indotineae. 

We recommend confirmatory testing because ringworm can easily be misdiagnosed as skin conditions such as psoriasis or eczema. The use of topical steroids can worsen a ringworm infection, so clinicians should be cautious about treating a rash with topical steroids if the etiology is unclear. Treatment should not be delayed if testing is not available. 

Clinicians who suspect a case of TMVII infection or infection with another emerging type of severe or antifungal-resistant ringworm can contact the Centers for Disease Control and Prevention (CDC) at fungaloutbreaks@cdc.gov. More details on how clinicians can pursue testing to identify emerging strains of ringworm can be found on the American Academy of Dermatology (AAD) emerging diseases task force website. 

How should clinicians treat and manage sexually transmitted ringworm? 

If TMVII infection is suspected, providers can consider starting empirical treatment with oral terbinafine. Although data are limited, experience from case series suggests that TMVII may require oral antifungal treatment because it can cause severe skin infections and often does not improve with topical antifungals. Clinicians should advise patients that they may need prolonged treatment courses until the rash resolves, with possible need for treatment courses of 6-8 weeks or longer. 

Any diagnosis of a sexually transmitted infection is an opportunity to engage patients in comprehensive sexual health services. Patients with suspected sexually transmitted ringworm should be evaluated for HIV and other sexually transmitted infections, including syphilis, chlamydia, and gonorrhea; clinicians should discuss and facilitate access to other preventive services, such as HIV pre-exposure prophylaxis if the patient is HIV negative and at risk for HIV. Patients should also notify their partner(s) about the diagnosis. 

Is sexually transmitted ringworm a public health concern? 

It is important to know that very few cases of TMVII have been reported in the United States thus far. CDC continues to monitor emerging dermatophyte strains because these types of ringworm can cause more severe or difficult-to-treat infections. Clinicians should be aware of the potential severity of sexually transmitted ringworm infections and of how diagnosis and treatment of these infections may differ from typical management of ringworm.

So far, TMVII, the dermatophyte strain most associated with spread through sexual contact, has not been documented to have antifungal resistance. More rarely, sexually transmitted ringworm may be caused by other emerging dermatophyte strains that are antifungal resistant, such as T indotineae. Itraconazole is the recommended first-line treatment for T indotineae infections. 

How can clinicians counsel patients with sexually transmitted ringworm?

Ringworm can spread with skin-to-skin contact, so patients should avoid such contact with others while they have a rash. They should also avoid sharing personal items (such as razors or towels) and clothing, and launder their clothing, towels, and bedding in a high heat cycle. 

People can reduce their risk of getting all types of ringworm infection by keeping their skin clean and dry, changing their socks and underwear daily, and wearing sandals in public locker rooms and other public spaces. People should avoid skin-to-skin contact with anyone with ringworm or an unexplained rash. Before having sex, people can check in with their partners and be aware of unexplained rashes on their partners’ bodies.

Where can clinicians go to learn more about sexually transmitted and other emerging types of ringworm?

CDC has partnered with the AAD to create set of online resources for clinicians for diagnosing and managing emerging dermatophyte infections. Clinicians who suspect or confirm antimicrobial resistant ringworm infection are also encouraged to submit cases to the AAD’s Emerging Diseases Registry. Clinicians wanting further guidance on how to manage suspected or confirmed ringworm infection with an emerging dermatophyte strain can also contact the CDC at fungaloutbreaks@cdc.gov. Useful information on emerging dermatophyte infections for providers and patients is also available on CDC’s website.

How can testing help guide the diagnosis of sexually transmitted ringworm infection?

When evaluating a rash that may represent ringworm, providers should use a confirmatory test such as potassium hydroxide (KOH) preparation when possible. KOH prep can confirm the presence of a fungus that causes ringworm, but it does not identify the species or type of ringworm. Testing such as fungal culture and molecular testing can help identify specific types of ringworm, but these tests are not often performed and may take a long time to yield results.

Routine fungal cultures cannot identify TMVII and T indotineae; these tests may identify the genus Trichophyton, but only advanced molecular testing, which is available at selected US laboratories, can identify TMVII and T indotineae. 

We recommend confirmatory testing because ringworm can easily be misdiagnosed as skin conditions such as psoriasis or eczema. The use of topical steroids can worsen a ringworm infection, so clinicians should be cautious about treating a rash with topical steroids if the etiology is unclear. Treatment should not be delayed if testing is not available. 

Clinicians who suspect a case of TMVII infection or infection with another emerging type of severe or antifungal-resistant ringworm can contact the Centers for Disease Control and Prevention (CDC) at fungaloutbreaks@cdc.gov. More details on how clinicians can pursue testing to identify emerging strains of ringworm can be found on the American Academy of Dermatology (AAD) emerging diseases task force website. 

How should clinicians treat and manage sexually transmitted ringworm? 

If TMVII infection is suspected, providers can consider starting empirical treatment with oral terbinafine. Although data are limited, experience from case series suggests that TMVII may require oral antifungal treatment because it can cause severe skin infections and often does not improve with topical antifungals. Clinicians should advise patients that they may need prolonged treatment courses until the rash resolves, with possible need for treatment courses of 6-8 weeks or longer. 

Any diagnosis of a sexually transmitted infection is an opportunity to engage patients in comprehensive sexual health services. Patients with suspected sexually transmitted ringworm should be evaluated for HIV and other sexually transmitted infections, including syphilis, chlamydia, and gonorrhea; clinicians should discuss and facilitate access to other preventive services, such as HIV pre-exposure prophylaxis if the patient is HIV negative and at risk for HIV. Patients should also notify their partner(s) about the diagnosis. 

Is sexually transmitted ringworm a public health concern? 

It is important to know that very few cases of TMVII have been reported in the United States thus far. CDC continues to monitor emerging dermatophyte strains because these types of ringworm can cause more severe or difficult-to-treat infections. Clinicians should be aware of the potential severity of sexually transmitted ringworm infections and of how diagnosis and treatment of these infections may differ from typical management of ringworm.

So far, TMVII, the dermatophyte strain most associated with spread through sexual contact, has not been documented to have antifungal resistance. More rarely, sexually transmitted ringworm may be caused by other emerging dermatophyte strains that are antifungal resistant, such as T indotineae. Itraconazole is the recommended first-line treatment for T indotineae infections. 

How can clinicians counsel patients with sexually transmitted ringworm?

Ringworm can spread with skin-to-skin contact, so patients should avoid such contact with others while they have a rash. They should also avoid sharing personal items (such as razors or towels) and clothing, and launder their clothing, towels, and bedding in a high heat cycle. 

People can reduce their risk of getting all types of ringworm infection by keeping their skin clean and dry, changing their socks and underwear daily, and wearing sandals in public locker rooms and other public spaces. People should avoid skin-to-skin contact with anyone with ringworm or an unexplained rash. Before having sex, people can check in with their partners and be aware of unexplained rashes on their partners’ bodies.

Where can clinicians go to learn more about sexually transmitted and other emerging types of ringworm?

CDC has partnered with the AAD to create set of online resources for clinicians for diagnosing and managing emerging dermatophyte infections. Clinicians who suspect or confirm antimicrobial resistant ringworm infection are also encouraged to submit cases to the AAD’s Emerging Diseases Registry. Clinicians wanting further guidance on how to manage suspected or confirmed ringworm infection with an emerging dermatophyte strain can also contact the CDC at fungaloutbreaks@cdc.gov. Useful information on emerging dermatophyte infections for providers and patients is also available on CDC’s website.

Ringworm (also known as tinea, jock itch, or athlete’s foot) is a common infection caused by dermatophyte fungi, known to affect skin, hair, or nails. It causes skin infections that are typically mild and are often treated with topical antifungals.

However, in recent years, newly emerging dermatophyte strains have been causing more severe and harder-to-treat ringworm. Notably, one emerging strain, Trichophyton mentagrophytes genotype VII(TMVII), is associated with sexual contact. In recent years, TMVII infections linked to sexual contact have been reported among men who have sex with men in Europe and in travelers returning from Southeast Asia. The first US case of TMVII was reported in June 2024, after which public health authorities were alerted to additional cases; all were associated with recent sexual contact. Other dermatophyte species have also been reported to cause ringworm transmitted through sexual contact. 

Here are some key points to know about sexually transmitted ringworm. 

Tell me more about sexually transmitted ringworm: What is causing it?

Skin-to-skin contact is a common mode of ringworm transmission. In recent years, transmission of ringworm via intimate or sexual contact has been increasingly recognized. However, clinicians may not immediately consider ringworm when evaluating genital, facial, or perianal lesions. Infections with sexually transmitted TMVII commonly cause lesions on anatomical sites that may be exposed during intimate or sexual contact, such as the face, genitals, and perianal region. Sexual transmission of TMVII has been reported in Europe, predominantly among men who have sex with men, for several years. Other dermatophyte strains have been reported in association with sexual contact, including the emerging strain Trichophyton indotineae. However, sexual transmission is not the main mode of transmission for T indotineae and other dermatophyte strains. 

When should clinicians suspect a potential case of sexually transmitted ringworm?

Providers should consider sexually transmitted ringworm when seeing ringworm in locations associated with intimate contact (for example, a rash on or around the genitals, perianal area, or mouth). 

The typical appearance of ringworm is a raised, ring-like, erythematous rash with a scaly border that grows over time. The rash may appear pink, brown, or gray on different types of skin. Patients may note itching and flaking of the rash. In areas with hair such as the beard area, ringworm can present as pustules and be associated with hair loss.

Emerging ringworm infections can present in atypical or more severe ways, including a highly inflammatory (painful, scarring, or otherwise severe) rash, a rash affecting a large area or multiple sites, nodules, and pustules. 

Sexually transmitted ringworm may be considered based on sexual history and recent sexual contact with someone with known TMVII. Recent history of travel to a region with reported sexually transmitted ringworm may increase suspicion of TMVII. In patients with a travel history to South Asia, T indotineae should be considered, especially if the rash does not improve with oral terbinafine. 

How can testing help guide the diagnosis of sexually transmitted ringworm infection?

The story of antimicrobial peptides (AMPs), particularly in tackling antibiotic resistance, has been one of false dawns and unfulfilled promises. But perhaps a new generation of “smarter” compounds could see them find a wider role in clinical practice, said experts.

AMPs may be small molecules, consisting of short chains of amino acids, but these naturally occurring compounds have an important function: They are the “frontline defense” against invasive bacteria, said Henrik Franzyk, MSc Engineering, associate professor in the Department of Drug Design and Pharmacology at the University of Copenhagen in Denmark.

 

Multifunction Line of Defense

AMPs are cationic, meaning they are positively charged. “The reason why nature has maintained these molecules is that all the microbes out there have a negative surface charge,” explained Hans-Georg Sahl, PhD, emeritus professor of pharmaceutical microbiology at the University of Bonn in Germany.

While AMPs are also hydrophobic, they are often amphipathic, with both hydrophobic and hydrophilic regions that allow them to target cell membranes and cause them to rupture similarly to how detergent acts. 

“Thus, the content of a cell gets released, and it destroys the pathogen,” explained Paulina Szymczak, a PhD candidate in the Institute of AI for Health at Helmholtz Munich, Neuherberg, Germany.

“There are variations of that theme,” said Eefjan Breukink, PhD, professor of microbial membranes and antibiotics at Utrecht University in the Netherlands. “And then it depends on the sequence of the particular peptide,” as some can cross the cell membrane and damage the bacterium internally.

Szymczak explained that AMPs can, in this way, target the cell DNA, as both the membrane and the DNA are negatively charged. “That’s also what makes them so powerful because they don’t have just one mechanism of action, as opposed to conventional antibiotics.” 

 

Indiscriminate Killers

But they also have another crucial function. They activate the innate immune system via so-called resident immune cells that are “sitting in the tissues and waiting for bacteria to turn up,” explained Franzyk.

“The problem with antibodies is that they typically need to replicate,” he continued, which takes between 4 and 7 days — a timeline that is much better suited to tackling a viral infection. Bacteria, on the other hand, have a replication cycle of just 30 minutes.

Another big problem is that AMPs kill cells indiscriminately, including our own.

“But the human body is clever in that it only produces these antimicrobial peptides where the bacteria are, so they are not circulating in the blood,” said Franzyk. If a small part of tissue becomes infected, the innate immune cells start producing AMPs, which may kill the bacteria, or call on other immune cells to help.

As part of this process, “they will also kill part of our own tissue, but that’s the price we have to pay,” he said.

 

Local Applications

It is this aspect that has, so far, limited the use of AMPs in clinical practice, certainly as a replacement for conventional antibiotics limited by bacterial resistance. The trials conducted so far have been, by and large, negative, which has dampened enthusiasm and led to the perception that the risk they pose is too great for large-scale investment.

AMPs “are not made for what we need from antibiotics in the first place,” explained Sahl. “That is, a nice, easy distribution in the body, going into abscesses” and throughout the tissues.

He continued that AMPs are “more about controlling the flora in our bodies,” and they are “really not made for being used systemically.” 

Szymczak and colleagues are now working on designing active peptides with a strong antibacterial profile but limited toxicity for systematic use.

However, the “downside with these peptides is that they are not orally available, so you can’t take a pill,” Breukink said, but instead they need to be administered intravenously.

There are, nevertheless, some antibiotics in clinical use that have the same molecular features as AMPs. These include colistin, a last-resort treatment for multidrug-resistant gram-negative bacteria, and daptomycin, which is used in the treatment of systemic infections caused by gram-positive species.

Szymczak added that there have been successes in using AMPs in a more targeted way, such as using a topical cream. Another potentially promising avenue is lung infections, which are being studied in mouse models.

 

Less Prone to Resistance

Crucially, AMPs are markedly less prone to bacterial resistance than conventional antibiotics, partly because of their typical target: the cell membrane.

“Biologically and evolutionarily, it is a very costly operation to rebuild the membrane and change its charge,” Szymczak explained. “It’s quite hard for bacteria to learn this because it’s not a single protein that you have to mutate but the whole membrane.”

This is seen in the laboratory, where it takes around five generations, or passages, for bacteria to develop resistance when grown in the presence of antibiotics, but up to 40 passages when cultured with an AMP.

The limits of the ability of AMPs to withstand the development of bacterial resistance have been tested in the real world.

Colistin has been used widely in Asia as a growth promoter, especially in pig farming. Franzyk explained that farmers have used enormous quantities of this AMP-based antibiotic, which has indeed led to the development of resistance, including contamination of meat for human consumption, leading to resistance spreading to other parts of the world.

“The bad thing about this is it’s not something each individual bacteria needs to acquire,” he said. Because resistance is stored on small, cyclic DNA called plasmids, it “can be transferred from one bacterial species to another.”

 

Novel Avenues

Franzyk suggested that AMPs could nevertheless be used in combination with, or to modify, existing antibiotics to revitalize those for which there is already bacterial resistance, or to allow antibiotics that ordinarily target only gram-positive bacteria to also treat gram-negative infections, for example.

Szymczak and her colleagues are using artificial intelligence to design novel AMP candidates. Instead of manually going through compounds and checking their activity profiles in the lab, those steps are carried out computationally “so that, in the end, you synthesize as few candidates as possible” and can proceed to a mouse model “as fast as possible.”

She personally is looking at the issue of strain-specific activity to design a compound that would target, for example, only multidrug-resistant strains. “What we can do now is something that will target everything, so a kind of last resort peptide. But we are trying to make them smarter in their targets.”

Szymczak also pointed out that cancer cells are “negatively charged, similarly to bacterial cells, as opposed to mammalian cells, which are neutral.”

“So in theory, maybe we could design something that will target cancer cells but not our host cells, and that would be extremely exciting.” However, she underlined that, first, they are trying to tackle antimicrobial resistance before looking at other spaces.

Finally, Breukink is screening for small antibacterial compounds in fungi that are around half the size of a normal peptide and more hydrophobic, meaning there is a much greater chance of them being orally available.

But “you first have to test, of course,” he said, as “if you don’t have specific targets, then you will get problems with toxicity, or other issues that you do not foresee.”

• The 2018 guidelines from the Infectious Disease Society of America recommend prompt administration of oseltamivir to hospitalized patients with suspected or confirmed influenza, regardless of the time of symptom onset; however, variations in treatment practices and circulating virus strains may affect the effectiveness of this practice guideline.
• Researchers conducted a multicenter observational study across 24 hospitals in the United States during the 2022-2023 flu season to assess the benefits of initiating oseltamivir treatment on the same day as hospital admission for adults with acute influenza, compared with late or no treatment.
• They included 840 adults (age, ≥ 18 years) with laboratory-confirmed influenza, of which 415 patients initiated oseltamivir on the same day as hospital admission (early treatment).
• Among the 425 patients in the late/no treatment group, most (78%) received oseltamivir 1 day after admission, while 124 did not receive oseltamivir at all.
• The primary outcome was the peak pulmonary disease severity level that patients experienced during hospitalization, and secondary outcomes included hospital length of stay, ICU admission, initiation of extrapulmonary organ support using vasopressors or kidney replacement therapy, and in-hospital death.

TAKEAWAY:

• Patients in the early treatment group were less likely to experience progression and severe progression of pulmonary disease after the day of hospital admission, compared with those in the late or no treatment group (P < .001 and P = .027, respectively).
• Patients who received early oseltamivir treatment had 40% lower peak pulmonary disease severity than those who received late or no treatment (proportional adjusted odds ratio [paOR], 0.60; 95% CI, 0.49-0.72).
• They also showed lower odds of ICU admission (aOR, 0.25; 95% CI, 0.13-0.49) and use of acute kidney replacement therapy or vasopressors (aOR, 0.40; 95% CI, 0.22-0.67).
• Those in the early treatment group also had a shorter hospital length of stay (median, 4 days vs 4 days) and faced a 64% lower risk for in-hospital mortality (aOR, 0.36; 95% CI, 0.19-0.69) compared with those in the late or no treatment group.

IN PRACTICE:

“These findings support current recommendations, such as the IDSA [Infectious Disease Society of America] Influenza Clinical Practice Guidelines and CDC [Centers for Disease Control and Prevention] guidance, to initiate oseltamivir treatment as soon as possible for adult patients hospitalized with influenza,” the authors wrote.

SOURCE:

The study was led by Nathaniel M. Lewis, PhD, Influenza Division, CDC, Atlanta, Georgia, and was published online  in Clinical Infectious Diseases.

LIMITATIONS:

This study may not be generalizable to seasons when influenza A(H1N1)pdm09 or B viruses are predominant as it was conducted during an influenza A(H3N2) virus–predominant season. The study lacked sufficient power to examine various oseltamivir treatment initiation timepoints or identify a potential maximum time-to-treatment threshold for effectiveness. Moreover, variables such as outpatient antiviral treatment before hospital admission and other treatments using macrolides, statins, corticosteroids, or immunomodulators before or during hospitalization were not collected, which may have influenced the study findings.

DISCLOSURES:

The study received funding from the CDC and the National Center for Immunization and Respiratory Diseases. Some authors reported receiving research support, consulting fees, funding, grants, or fees for participation in an advisory board and having other ties with certain institutions and pharmaceutical companies.

The updated COVID vaccines for 2024-2025 are officially here, designed to target the latest variants and offer robust protection — but getting Americans to roll up their sleeves could prove harder than ever. With COVID cases on the decline, many people feel the urgency has passed.

As of December 2, the CDC reports that COVID test positivity remains low, rising slightly to 4.5% for the week ending November 23, compared with 4.2% the previous week. That’s a far cry from the early days of 2022, when positivity rates soared above 30%. Emergency room visits for COVID now make up just 0.5%, and deaths are down to 0.8% of total weekly fatalities, compared to 1% the previous week.

This steady improvement in the numbers may explain why a recent Pew Research Center survey revealed that 6 in 10 US adults have no plans to get the updated vaccine this year.

As of December 2, according to the CDC, just 19.7% of the US adult population and 9.4% of children had gotten the updated vaccine. The age group most likely? Adults ages 65 and older, with 41.6% getting the updated shot.

Despite the good news about declining cases, our pandemic history suggests a pre-holiday increase is likely. On November 20, the CDC warned it expects levels of both COVID and RSV (respiratory syncytial virus) to rise in the coming weeks — the familiar post-Thanksgiving, pre-Christmas, and Hanukkah increase.

Here’s what to know about the 2024-2025 vaccines — what’s available, how the updated versions are tested, how well each protects you, side effects and other safety information, the best time to get them, and where.



 

What’s Available?

Three updated vaccines, which work two different ways, are authorized or licensed by the FDA for the 2024-2025 season:

Novavax. A protein subunit vaccine, Novavax is authorized for emergency use by the FDA in people ages 12 and older. The vaccine makes a protein that mimics the SARS-CoV-2 virus’ version of the spike protein and combines it with an adjuvant or “booster” to stimulate a protective immune response. This year’s version targets the JN.1 variant.

Pfizer/BioNTech. Its Comirnaty is a fully licensed vaccine for people ages 12 and older. Its mechanism of action is by messenger RNA (mRNA). It works by instructing cells to produce viral proteins, triggering an immune response. Pfizer’s COVID vaccine is authorized for emergency use in children ages 6 months to 11 years. This year’s version targets KP.2.

Moderna. Its Spikevax is a fully licensed vaccine for people ages 12 and older. It is also an mRNA vaccine. Moderna’s COVID-19 vaccine is authorized for emergency use in children ages 6 months to 11 years. This year’s version targets KP.2.

 

How Effective Are They?

Before being approved for this year’s use, each company had to show its updated vaccine is effective against the currently circulating variants. For the 2 weeks ending November 23, KP.3.1.1 and XEC, from the Omicron lineage, made up the majority of cases, according to CDC data.

How do the vaccine makers know their updated vaccines are targeting the circulating variants? The companies use “pre-clinical” data, which means the updated versions have not yet been tested in people but in other ways, such as animal studies. But they do have to prove to the FDA that their updated vaccine can neutralize the circulating variants.

Companies continue to monitor their updated vaccines as new variants appear. Later in the season, there will be more specific information about how well each vaccine protects in people after tracking real-world data.

 

What About Side Effects?

The CDC lists comparable side effects for both mRNA and protein COVID vaccines, including pain and soreness from the needle, fatigue, headache, muscle pain joint pain, chills, fever, nausea, and vomiting.

Severe allergic reactions are rare, the CDC says, but cautions to be alert for low blood pressure, swelling of the lips, tongue, or throat, or difficulty breathing.

 

Which One Is Best?

“I consider the three currently available COVID vaccines — Pfizer, Moderna, and Novavax — interchangeable,’’ said Scott Roberts, MD, an infectious diseases specialist and assistant professor of medicine at Yale School of Medicine in New Haven, Connecticut. “There have not been head-to-head studies, and the initial vaccine studies for each were performed at different phases of the pandemic, so we do not have great data to guide which one is better than another.”

He does point out the different mechanisms of action, which may make a difference in people’s choice of vaccines. “So if someone has a reaction to one of them, they can switch to a different brand.”

 

Best Time to Get It?

“We have consistently seen COVID rates rise quite significantly in the winter season, especially around the holidays. So if anyone is on the fence and hasn’t gotten the updated vaccine yet, now is a great time to get it to maximize immunity for the holidays,” he said.

What’s next? In late October, the CDC recommended a second dose of the 2024-2025 vaccine 6 months after the first one for those age 65 and above and those 6 months old and older who are moderately or severely immunocompromised.

Now, while it’s tempting to think rates are down and will continue to drop steadily, Roberts reminds people that pandemic history suggests otherwise.

 

Coverage

Most people can get COVID-19 vaccines at no cost through their private health insurance, Medicaid, or Medicare. For the uninsured, there’s also the Vaccines for Children (VFC) program or access through state and local health departments and some health centers. Find details on the CDC website.

Instead of sitting behind a laptop during patient visits, the pediatrician directly faces the patient and parent, relying on an ambient artificial intelligence (AI) scribe to capture the conversation for the electronic health record (EHR). A geriatrician doing rounds at the senior living facility plugs each patient’s medications into an AI tool, checking for drug interactions. And a busy hospital radiology department runs all its emergency head CTs through an AI algorithm, triaging potential stroke patients to ensure they receive the highest priority. None of these physicians have been sued for malpractice for AI usage, but they wonder if they’re at risk.

In a recent Medscape report, AI Adoption in Healthcare, 224 physicians responded to the statement: “I want to do more with AI but I worry about malpractice risk if I move too fast.” Seventeen percent said that they strongly agreed while 23% said they agreed — a full 40% were concerned about using the technology for legal reasons.  

Malpractice and AI are on many minds in healthcare, especially in large health systems, Deepika Srivastava, chief operating officer at The Doctors Company, told this news organization. “AI is at the forefront of the conversation, and they’re [large health systems] raising questions. Larger systems want to protect themselves.” 

The good news is there’s currently no sign of legal action over the clinical use of AI. “We’re not seeing even a few AI-related suits just yet,” but the risk is growing, Srivastava said, “and that’s why we’re talking about it. The legal system will need to adapt to address the role of AI in healthcare.”

 

How Doctors Are Using AI

Healthcare is incorporating AI in multiple ways based on the type of tool and function needed. Narrow AI is popular in fields like radiology, comparing two large data sets to find differences between them. Narrow AI can help differentiate between normal and abnormal tissue, such as breast or lung tumors. Almost 900 AI health tools have Food and Drug Administration approval as of July 2024, discerning abnormalities and recognizing patterns better than many humans, said Robert Pearl, MD, author of ChatGPT, MD: How AI-Empowered Patients & Doctors Can Take Back Control of American Medicine and former CEO of The Permanente Medical Group.

Narrow AI can improve diagnostic speed and accuracy for other specialties, too, including dermatology and ophthalmology, Pearl said. “It’s less clear to me if it will be very beneficial in primary care, neurology, and psychiatry, areas of medicine that involve a lot of words.” In those specialties, some may use generative AI as a repository of resources. In clinical practice, ambient AI is also used to create health records based on patient/clinician conversations.

In clinical administration, AI is used for scheduling, billing, and submitting insurance claims. On the insurer side, denying claims based on AI algorithms has been at the heart of legal actions, making recent headlines. 

 

Malpractice Risks When Using AI

Accuracy and privacy should be at the top of the list for malpractice concerns with AI. With accuracy, liability could partially be determined by use type. If a diagnostic application makes the wrong diagnosis, “the company has legal accountability because it created and had to test it specific to the application that it’s being recommended for,” Pearl said. 

However, keeping a human in the loop is a smart move when using AI diagnostic tools. The physician should still choose the AI-suggested diagnosis or a different one. If it’s the wrong diagnosis, “it’s really hard to currently say where is the source of the error? Was it the physician? Was it the tool?” Srivastava added.

With an incorrect diagnosis by generative AI, liability is more apparent. “You’re taking that accountability,” Pearl said. Generative AI operates in a black box, predicting the correct answer based on information stored in a database. “Generative AI tries to draw a correlation between what it has seen and predicting the next output,” said Alex Shahrestani, managing partner of Promise Legal PLLC, a law firm in Austin, Texas. He serves on the State Bar of Texas’s Taskforce on AI and the Law and has participated in advisory groups related to AI policies with the National Institute of Standards and Technology. “A doctor should know to validate information given back to them by AI,” applying their own medical training and judgment.

Generative AI can provide ideas. Pearl shared a story about a surgeon who was unable to remove a breathing tube that was stuck in a patients’ throat at the end of a procedure. The surgeon checked ChatGPT in the operating room, finding a similar case. Adrenaline in the anesthetic restricted the blood vessels, causing the vocal cords to stick together. Following the AI information, the surgeon allowed more time for the anesthesia to diffuse. As it wore off, the vocal cords separated, easing the removal of the breathing tube. “That is the kind of expertise it can provide,” Pearl said.

Privacy is a common AI concern, but it may be more problematic than it should be. “Many think if you talk to an AI system, you’re surrendering personal information the model can learn from,” said Shahrestani. Platforms offer opt-outs. Even without opting out, the model won’t automatically ingest your interactions. That’s not a privacy feature, but a concern by the developer that the information may not help the model. 

“If you do use these opt-out mechanisms, and you have the requisite amount of confidentiality, you can use ChatGPT without too much concern about the patient information being released into the wild,” Shahrestani said. Or use systems with stricter requirements that keep all data on site.

Currently, malpractice policies do not specify AI coverage. “We don’t ask right now to list all the technology you’re using,” said Srivastava. Many EHR systems already incorporate AI. If a human provider is in the loop, already vetted and insured, “we should be okay when it comes to the risk of malpractice when doctors are using AI because it’s still the risk that we’re ensuring.”

Insurers are paying attention, though. “Traditional medical malpractice law does require re-evaluation because the rapid pace of AI development has outpaced the efforts to integrate it into the legal system,” Srivastava said.

Some, including Pearl, believe AI will actually lower the malpractice risk. Having more data points to consider can make doctors’ jobs faster, easier, and more accurate. “I believe the technology will decrease lawsuits, not increase them,” said Pearl.

 

Meanwhile, How Can Doctors Protect Themselves From an AI Malpractice Suit?

Know your tool: Providers should understand the tool they’re deploying, what it provides, how it was built and trained (including potential biases), how it was tested, and the guidelines for how to use it or not use it, said Srivastava. Evaluate each tool, use case, and risk separately. “Don’t just say it’s all AI.” 

With generative AI, users will have better success requesting information that has been available longer and is more widely accessed. “It’s more likely to come back correctly,” said Shahrestani. If the information sought is fairly new or not widespread, the tool may try to draw problematic conclusions. 

Document: “Document, document, document. Just making sure you have good documentation can really help you if litigation comes up and it’s related to the AI tools,” Srivastava said.

Try it out: “I recommend you use [generative AI] a lot so you understand its strengths and shortcomings,” said Shahrestani. “If you wait until things settle, you’ll be further behind.” 

Pretend you’re the patient and give the tool the information you’d give a doctor and see the results, said Pearl. It will provide you with an idea of what it can do. “No one would sue you because you went to the library to look up information in the textbooks,” he said — using generative AI is similar. Try the free versions first; if you begin relying on it more, the paid versions have better features and are inexpensive.

Instead of sitting behind a laptop during patient visits, the pediatrician directly faces the patient and parent, relying on an ambient artificial intelligence (AI) scribe to capture the conversation for the electronic health record (EHR). A geriatrician doing rounds at the senior living facility plugs each patient’s medications into an AI tool, checking for drug interactions. And a busy hospital radiology department runs all its emergency head CTs through an AI algorithm, triaging potential stroke patients to ensure they receive the highest priority. None of these physicians have been sued for malpractice for AI usage, but they wonder if they’re at risk.

In a recent Medscape report, AI Adoption in Healthcare, 224 physicians responded to the statement: “I want to do more with AI but I worry about malpractice risk if I move too fast.” Seventeen percent said that they strongly agreed while 23% said they agreed — a full 40% were concerned about using the technology for legal reasons.  

Malpractice and AI are on many minds in healthcare, especially in large health systems, Deepika Srivastava, chief operating officer at The Doctors Company, told this news organization. “AI is at the forefront of the conversation, and they’re [large health systems] raising questions. Larger systems want to protect themselves.” 

The good news is there’s currently no sign of legal action over the clinical use of AI. “We’re not seeing even a few AI-related suits just yet,” but the risk is growing, Srivastava said, “and that’s why we’re talking about it. The legal system will need to adapt to address the role of AI in healthcare.”

 

How Doctors Are Using AI

Healthcare is incorporating AI in multiple ways based on the type of tool and function needed. Narrow AI is popular in fields like radiology, comparing two large data sets to find differences between them. Narrow AI can help differentiate between normal and abnormal tissue, such as breast or lung tumors. Almost 900 AI health tools have Food and Drug Administration approval as of July 2024, discerning abnormalities and recognizing patterns better than many humans, said Robert Pearl, MD, author of ChatGPT, MD: How AI-Empowered Patients & Doctors Can Take Back Control of American Medicine and former CEO of The Permanente Medical Group.

Narrow AI can improve diagnostic speed and accuracy for other specialties, too, including dermatology and ophthalmology, Pearl said. “It’s less clear to me if it will be very beneficial in primary care, neurology, and psychiatry, areas of medicine that involve a lot of words.” In those specialties, some may use generative AI as a repository of resources. In clinical practice, ambient AI is also used to create health records based on patient/clinician conversations.

In clinical administration, AI is used for scheduling, billing, and submitting insurance claims. On the insurer side, denying claims based on AI algorithms has been at the heart of legal actions, making recent headlines. 

 

Malpractice Risks When Using AI

Accuracy and privacy should be at the top of the list for malpractice concerns with AI. With accuracy, liability could partially be determined by use type. If a diagnostic application makes the wrong diagnosis, “the company has legal accountability because it created and had to test it specific to the application that it’s being recommended for,” Pearl said. 

However, keeping a human in the loop is a smart move when using AI diagnostic tools. The physician should still choose the AI-suggested diagnosis or a different one. If it’s the wrong diagnosis, “it’s really hard to currently say where is the source of the error? Was it the physician? Was it the tool?” Srivastava added.

With an incorrect diagnosis by generative AI, liability is more apparent. “You’re taking that accountability,” Pearl said. Generative AI operates in a black box, predicting the correct answer based on information stored in a database. “Generative AI tries to draw a correlation between what it has seen and predicting the next output,” said Alex Shahrestani, managing partner of Promise Legal PLLC, a law firm in Austin, Texas. He serves on the State Bar of Texas’s Taskforce on AI and the Law and has participated in advisory groups related to AI policies with the National Institute of Standards and Technology. “A doctor should know to validate information given back to them by AI,” applying their own medical training and judgment.

Generative AI can provide ideas. Pearl shared a story about a surgeon who was unable to remove a breathing tube that was stuck in a patients’ throat at the end of a procedure. The surgeon checked ChatGPT in the operating room, finding a similar case. Adrenaline in the anesthetic restricted the blood vessels, causing the vocal cords to stick together. Following the AI information, the surgeon allowed more time for the anesthesia to diffuse. As it wore off, the vocal cords separated, easing the removal of the breathing tube. “That is the kind of expertise it can provide,” Pearl said.

Privacy is a common AI concern, but it may be more problematic than it should be. “Many think if you talk to an AI system, you’re surrendering personal information the model can learn from,” said Shahrestani. Platforms offer opt-outs. Even without opting out, the model won’t automatically ingest your interactions. That’s not a privacy feature, but a concern by the developer that the information may not help the model. 

“If you do use these opt-out mechanisms, and you have the requisite amount of confidentiality, you can use ChatGPT without too much concern about the patient information being released into the wild,” Shahrestani said. Or use systems with stricter requirements that keep all data on site.
