MDedge Pediatrics

Only one third of pediatric patients were correctly triaged at emergency departments (EDs) in a northern California health care system, according to a multicenter retrospective study published in JAMA Pediatrics. Researchers also identified gender, age, race, ethnicity, and comorbidity disparities in those who were undertriaged.

The researchers found that only 34.1% of visits were correctly triaged while 58.5% were overtriaged and 7.4% were undertriaged. The findings were based on analysis of more than 1 million pediatric emergency visits over a 5-year period that used the Emergency Severity Index (ESI) version 4 for triage.

“The ESI had poor sensitivity in identifying a critically ill pediatric patient, and undertriage occurred in 1 in 14 children,” wrote Dana R. Sax, MD, a senior emergency physician at The Permanente Medical Group in northern California, and her colleagues.

Disparities in Emergency Care

The results underscore the need for more work to address disparities in emergency care, wrote Warren D. Frankenberger, PhD, RN, a nurse scientist at Children’s Hospital of Philadelphia, and two colleagues in an accompanying editorial.

“Decisions in triage can have significant downstream effects on subsequent care during the ED visit,” they wrote in their editorial. “Given that the triage process in most instances is fully executed by nurses, nurse researchers are in a key position to evaluate these and other covariates to influence further improvements in triage.” They suggested that use of clinical decision support tools and artificial intelligence (AI) may improve the triage process, albeit with the caveat that AI often relies on models with pre-existing historical bias that may perpetuate structural inequalities.
 

Study Methodology

The researchers analyzed 1,016,816 pediatric visits at 21 emergency departments in Kaiser Permanente Northern California between January 2016 and December 2020. The patients were an average 7 years old, and 47% were female. The researchers excluded visits that lacked ESI data or had incomplete ED time variables as well as those with patients who left against medical advice, were not seen, or were transferred from another ED.

The study relied on novel definitions of ESI undertriage and overtriage developed through a modified Delphi process by a team of four emergency physicians, one pediatric emergency physician, two emergency nurses, and one pediatric ICU physician. The definition involved comparing ESI levels to the clinical outcomes and resource use.

Resources included laboratory analysis, electrocardiography, radiography, CT, MRI, diagnostic ultrasonography (not point of care), angiography, IV fluids, and IV, intramuscular, or nebulized medications. Resources did not include “oral medications, tetanus immunizations, point-of-care testing, history and physical examination, saline or heparin lock, prescription refills, simple wound care, crutches, splints, and slings.”

Level 1 events were those requiring time-sensitive, critical intervention, including high-risk sepsis. Level 2 events included most level 1 events that occurred after the first hour (except operating room admission or hospital transfer) as well as respiratory therapy, toxicology consult, lumbar puncture, suicidality as chief concern, at least 2 doses of albuterol or continuous albuterol nebulization, a skeletal survey x-ray order, and medical social work consult with an ED length of stay of at least 2 hours. Level 3 events included IV mediation order, any CT order, OR admission or hospital transfer after one hour, or any pediatric hospitalist consult.
 

Analyzing the ED Visits

Overtriaged cases were ESI level 1 or 2 cases in which fewer than 2 resources were used; level 3 cases where fewer than 2 resources were used and no level 1 or 2 events occurred; and level 4 cases where no resources were used.

Undertriaged cases were defined as the following:

• ESI level 5 cases where any resource was used and any level 1, 2, or 3 events occurred.
• Level 4 cases where more than 1 resource was used and any level 1, 2, or 3 events occurred.
• Level 3 cases where any level 1 event occurred, more than one level 2 event occurred, or any level 2 event occurred and more than one additional ED resource type was used.
• Level 2 cases where any level 1 event occurred.

About half the visits (51%) were assigned ESI 3, which was the category with the highest proportion of mistriage. After adjusting for study facility and triage vital signs, the researchers found that children age 6 and older were more likely to be undertriaged than those younger than 6, particularly those age 15 and older (relative risk [RR], 1.36).

Undertriage was also modestly more likely with male patients (female patients’ RR, 0.93), patients with comorbidities (RR, 1.11-1.2), patients who arrived by ambulance (RR, 1.04), and patients who were Asian (RR, 1.10), Black (RR, 1.05), or Hispanic (RR, 1.04). Undertriage became gradually less likely with each additional year in the study period, with an RR of 0.89 in 2019 and 2020.

Among the study’s limitations were use of ESI version 4, instead of the currently used 5, and the omission of common procedures from the outcome definition that “may systematically bias the analysis toward overtriage,” the editorial noted. The authors also did not include pain as a variable in the analysis, which can often indicate patient acuity.

Further, this study was unable to include covariates identified in other research that may influence clinical decision-making, such as “the presenting illness or injury, children with complex medical needs, and language proficiency,” Dr. Frankenberger and colleagues wrote. “Furthermore, environmental stressors, such as ED volume and crowding, can influence how a nurse prioritizes care and may increase bias in decision-making and/or increase practice variability.”

The study was funded by the Kaiser Permanente Northern California (KPNC) Community Health program. One author had consulting payments from CSL Behring and Abbott Point-of-Care, and six of the authors have received grant funding from the KPNC Community Health program. The editorial authors reported no conflicts of interest.

Bicycles have been woven into my life since I first straddled a hand-me-down with a fan belt drive when I was 3. At age 12 my friend Ricky and I took a 250 mile–plus 2-night adventure on our 3-speed “English” style bikes. We still marvel that our parents let us do it when neither cell phones nor GPS existed.

I have always bike commuted to work, including the years when that involved a perilous navigation into Boston from the suburbs. In our mid-50s my wife and I biked from Washington state back here to Maine with another couple unsupported. We continue to do at least one self-guided cycle tour out of the country each year.

Not surprisingly, I keep a close eye on what’s happening in the bicycle market. For decades the trends have shifted back and forth between sleek road models and beefier off-roaders. There have been boom years here and there for the dealers and manufacturers, but nothing like what the bike industry is experiencing now with the arrival of e-bikes on the market. Driven primarily by electrification, micromobility ridership (which includes conventional bikes and scooters) has grown more than 50-fold over the last 10 years. Projections suggest the market’s value will be $300 billion by 2030.

It doesn’t take an MBA with a major in marketing to understand the broad appeal of electrification. Most adults have ridden a bicycle as children, but several decades of gap years has left many of them with a level of fitness that makes pedaling against the wind or up any incline difficult and unappealing. An e-bike can put even the least fitness conscious back in the saddle and open the options for outdoor recreation they haven’t dreamed of since childhood.

In large part the people flocking to e-bikes are retiree’s who thought they were “over the hill.” They are having so much fun they don’t care if the Lycra-clad “serious” cyclists notice the battery bulge in the frame on their e-bikes. Another group of e-bike adopters are motivated by the “greenness” of a fossil-fuel–free electric powered transportation which, with minimal compromise, can be used as they would a car around town and for longer commutes than they would have considered on a purely pedal-powered bicycle.

Unfortunately, there is a growing group of younger e-bike riders who are motivated and uninhibited by the potential that the power boost of a small electric motor can provide. And here is where the ugliness begins to intrude on what was otherwise a beautiful and expanding landscape. With the increase in e-bike popularity, there has been an understandable increase in injuries in all age groups. However, it is the young who are, not surprisingly, drawn to the speed, and with any vehicle – motorized or conventional – as speed increases so does the frequency and seriousness of accidents.

The term e-bike covers a broad range of vehicles, from those designated class 1, which require pedaling and are limited to 20 miles per hour, to class 3, which may have a throttle and unmodified can hit 28 mph. Class 2 bikes have a throttle that will allow the rider to reach 20 mph without pedaling. Modifying any class of e-bike can substantially increase its speed, but this is more common in classes 2 and 3. As an example, some very fast micromobiles are considered unclassified e-bikes and avoid being labeled motorcycles simply because they have pedals.

One has to give some credit to the e-bike industry for eventually adopting this classification system. But, we must give the rest of us, including parents and public safety officials, a failing grade for doing a poor job of translating these scores into enforceable regulations to protect both riders and pedestrians from serious injury.

On the governmental side only a little more than half of US states have used the three category classification to craft their regulations. Many jurisdictions have failed to differentiate between streets, sidewalks, and trails. Regulations vary from state to state, and many states leave it up to local communities. From my experience chairing our town’s Bicycle and Pedestrian Advisory Committee, I can tell you that even “progressive” communities are struggling to decide who can ride what where. The result has been that people of all ages, but mostly adolescents, are traveling on busy streets and sidewalks at speeds that put themselves and pedestrians at risk.

On the parental side of the problem are families that have either allowed or enabled their children to ride class 2 and 3 e-bikes without proper safety equipment or consideration for the safety of the rest of the community. Currently, this is not much of a problem here in Maine thanks to the weather and the high price of e-bikes. However, I frequently visit an affluent community in the San Francisco Bay Area, where it is not uncommon to see middle school children speeding along well in excess of 20 mph.

Unfortunately this is another example, like television and cell phone, in which our society has been unable to keep up with technology by molding the behavior of our children and/or creating enforceable rules that allow us to reap the benefits of new discoveries while minimizing the collateral damage that can accompany them.

Many, many years ago there was a Thanksgiving when as I was just beginning to earn a reputation in my wife’s family. There were no place cards on the table and the usual hovering and jockeying seats was well underway. From behind me I heard one of my young nieces pipe up: “I want to sit next to Doctor I-don’t-know.”

After a few words of negotiation we were all settled in our places and ready to enjoy our meal. It took only a few seconds of introspection for me to grasp how I had received that moniker, which some physicians might consider disrespectful.

I was the only physician within several generations of that family and, as such, my in-laws thought it only appropriate to ask me medical questions. They courteously seemed to avoid personal questions about their own health and were particularly careful not to roll up their sleeves or unbutton their shirts to show me a lesion or a recently acquired surgical scar. No, my wife’s family members were curious. They wanted answers to deeper questions, the hard science so to speak. “How does aspirin work?” was a typical and painful example. Maybe pharmacologists today have better answers but 40 years ago I’m not so sure; I certainly didn’t know back then and would reply, “I don’t know.” Probably for the third or fourth time that day.

Usually I genuinely didn’t know the answer. However, sometimes my answer was going to be so different from the beliefs and biases of my inquisitor that, in the interest of expediency, “I don’t know” seemed the most appropriate response.

If you were reading Letters from Maine 25 years ago, that scenario might sound familiar. I have chosen to pull it out of the archives as a jumping-off point for a consideration of the unfortunate example some of us set when the COVID pandemic threw a tsunami of unknowns at us. Too many physician-“experts” were afraid to say, “I don’t know.” Instead, and maybe because, they themselves were afraid that the patients couldn’t handle the truth that none of us in the profession knew the correct answers. When so many initial pronouncements proved incorrect, it was too late to undo the damage that had been done to the community’s trust in the rest of us.

It turns out that my in-laws were not the only folks who thought of me as Doctor I-don’t-know. One of the perks of remaining in the same community after one retires is that encounters with former patients and their parents happen frequently. On more than one occasion a parent has thanked me for admitting my ignorance. Some have even claimed that my candid approach was what they remembered most fondly. And, that quality increased their trust when I finally provided an answer.

There is an art to delivering “I don’t know.” Thirty years ago I would excuse myself and tell the family I was going to my office to pull a book off the shelf or call a previous mentor. Now one only needs to ask Dr. Google. No need to leave the room. If appropriate, the provider can swing the computer screen so that the patient can share in the search for the answer.

That strategy only works when the provider merely needs to update or expand his/her knowledge. However, there are those difficult situations when no one could know the answer given the current parameters of the patient’s situation. More lab work might be needed. It may be too early in the trajectory of the patient’s illness for the illnesses signs and symptoms to declare themselves.

In these situations “I don’t know” must be followed by a “but.” It is what comes after that “but” and how it is delivered that can convert the provider’s admission of ignorance into a demonstration of his or her character. Is he/she a caring person trying to understand the patient’s concerns? Willing to enter into a cooperative relationship as together they search for the cause and hopefully for a cure for the patient’s currently mysterious illness?

I recently read about a physician who is encouraging medical educators to incorporate more discussions of “humility” and its role in patient care into the medical school and postgraduate training curricula. He feels, as do I, that if more physicians learned to say “I don’t know” early in their careers, the quality of care we are delivering as a profession will improve, as will the trust bestowed by our patients.

Dr. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years. He has authored several books on behavioral pediatrics, including “How to Say No to Your Toddler.” Other than a Littman stethoscope he accepted as a first-year medical student in 1966, Dr. Wilkoff reports having nothing to disclose.

Many, many years ago there was a Thanksgiving when as I was just beginning to earn a reputation in my wife’s family. There were no place cards on the table and the usual hovering and jockeying seats was well underway. From behind me I heard one of my young nieces pipe up: “I want to sit next to Doctor I-don’t-know.”

After a few words of negotiation we were all settled in our places and ready to enjoy our meal. It took only a few seconds of introspection for me to grasp how I had received that moniker, which some physicians might consider disrespectful.

I was the only physician within several generations of that family and, as such, my in-laws thought it only appropriate to ask me medical questions. They courteously seemed to avoid personal questions about their own health and were particularly careful not to roll up their sleeves or unbutton their shirts to show me a lesion or a recently acquired surgical scar. No, my wife’s family members were curious. They wanted answers to deeper questions, the hard science so to speak. “How does aspirin work?” was a typical and painful example.

TOPLINE:

Uptake of infliximab biosimilars rose slowly across private insurance, Medicaid, and Medicare when two were available in the United States during 2016-2020 but increased significantly through 2022 after the third biosimilar became available in July 2020. However, prescriptions in Medicare still lagged behind those in private insurance and Medicaid.

METHODOLOGY:

• Researchers analyzed electronic health records from over 1100 US rheumatologists who participated in a national registry, the Rheumatology Informatics System for Effectiveness (RISE), for all infliximab administrations (bio-originator or biosimilar) to patients older than 18 years from April 2016 to September 2022.
• They conducted an interrupted time series to account for autocorrelation and model the effect of each infliximab biosimilar release (infliximab-dyyb in November 2016, infliximab-abda in July 2017, and infliximab-axxq in July 2020) on uptake across Medicare, Medicaid, and private insurers.

TAKEAWAY:

• The researchers identified 659,988 infliximab administrations for 37,560 unique patients, with 52% on Medicare, 4.8% on Medicaid, and 43% on private insurance.
• Biosimilar uptake rose slowly with average annual increases < 5% from 2016 to June 2020 (Medicare, 3.2%; Medicaid, 5.2%; private insurance, 1.8%).
• After the third biosimilar release in July 2020, the average annual increase reached 13% for Medicaid and 16.4% for private insurance but remained low for Medicare (5.6%).
• By September 2022, biosimilar uptake was higher for Medicaid (43.8%) and private insurance (38.5%) than for Medicare (24%).

IN PRACTICE:

“Our results suggest policymakers may need to do more to allow biosimilars to get a foothold in the market by incentivizing the development and entry of multiple biosimilars, address anticompetitive pricing strategies, and may need to amend Medicare policy to [incentivize] uptake in order to ensure a competitive and sustainable biosimilar market that gradually reduces total drug expenditures and out-of-pocket costs over time,” wrote the authors of the study.

SOURCE:

The study was led by Eric T. Roberts, PhD, University of California, San Francisco. It was published online on July 30, 2024, in Arthritis & Rheumatology.

LIMITATIONS:

First, while the biosimilar introductions are likely catalysts for many changes in the market, some changes in slopes may also be attributable to the natural growth of the market over time. Second, this study may neither be generalizable to academic medical centers, which are underrepresented in RISE, nor be generalizable to infliximab prescriptions from other specialties. Third, uptake among privately insured patients changed shortly after November-December 2020, raising the possibility that the delay reflected negotiations between insurance companies and relevant entities regarding formulary coverage.

DISCLOSURES:

This study was funded by grants from the Agency for Healthcare Research and Quality and the National Institute of Arthritis and Musculoskeletal and Skin Diseases. One author disclosed receiving consulting fees from Pfizer, AstraZeneca, and Bristol-Myers Squibb and grant funding from AstraZeneca, the Bristol-Myers Squibb Foundation, and Aurinia.

TOPLINE:

Nemolizumab, an interleukin 31 receptor antagonist, was well tolerated and significantly improved inflammation and pruritus in patients with moderate to severe atopic dermatitis (AD).

METHODOLOGY:

• The researchers conducted two 48-week randomized, double-blind, placebo-controlled phase 3 trials, ARCADIA 1 (n = 941; 47% women) and ARCADIA 2 (n = 787; 52% women), involving patients aged 12 and older with moderate to severe AD.
• Participants were randomly assigned in a 2:1 ratio to receive either 30 mg nemolizumab (with a 60-mg loading dose) or placebo, along with background topical corticosteroids with or without topical calcineurin inhibitors. The mean age range was 33.3-35.2 years.
• The coprimary endpoints were Investigator’s Global Assessment (IGA) success (score of 0 or 1 with at least a two-point improvement from baseline) and at least a 75% improvement in the Eczema Area and Severity Index (EASI-75) at week 16.

TAKEAWAY:

• At week 16, significantly more patients receiving nemolizumab vs placebo achieved IGA success in both the ARCADIA 1 (36% vs 25%; P = .0003) and ARCADIA 2 (38% vs 26%; P = .0006) trials.
• EASI-75 response rates were also significantly higher in the nemolizumab group than in the placebo group in both trials: ARCADIA 1 (44% vs 29%; P < .0001) and 2 (42% vs 30%; P = .0006).
• Significant improvements in pruritus were observed as early as week 1, with a greater proportion of participants in the nemolizumab vs placebo group achieving at least a four-point reduction in the Peak Pruritus Numerical Rating Scale score in both trials.
• Rates of adverse events were similar between the nemolizumab and placebo groups, with severe treatment-emergent adverse events occurring in 2%-4% of patients.

IN PRACTICE:

“Nemolizumab showed statistically and clinically significant improvements in inflammation and pruritus in adults and adolescents with moderate to severe atopic dermatitis and a rapid effect in reducing pruritus, as one of the primary complaints of patients. As such, nemolizumab might offer a valuable extension of the therapeutic armament if approved,” the authors concluded.

SOURCE:

The study was led by Jonathan Silverberg, MD, PhD, from the Department of Dermatology, George Washington University, Washington, DC. It was published online in The Lancet.

LIMITATIONS:

The study’s limitations included the absence of longer-term safety data. Additionally, the predominantly White population of the trials may limit the generalizability of the findings to other racial and ethnic groups. The use of concomitant topical therapy might have influenced the placebo response.

DISCLOSURES:

This study was funded by Galderma. Dr. Silverberg received honoraria from pharmaceutical companies, including Galderma, and his institution also received grants from Galderma, Incyte, and Pfizer. Four authors were employees of Galderma. Other authors also declared having ties with pharmaceutical companies, including Galderma, outside this work.

TORONTO — When it comes to using artificial intelligence (AI) in your practice, pediatric dermatologist Albert Yan, MD, professor of pediatrics and dermatology at the University of Pennsylvania, Philadelphia, suggests that dermatologists “just jump in” and become familiar with the various AI models.

He reminds doctors that many of their colleagues and patients and their families are already using these systems, “and you don’t want to be left behind.”

In an interview following his presentation on AI at the annual meeting of the Society for Pediatric Dermatology (SPD), Dr. Yan discussed his tips for using AI.
 

Changing Fast 

From the outset, most generative AI systems have been very good at processing language — for example, generating letters of medical necessity and summarizing disease processes into lay terms. But now they’re becoming “truly multimodal,” said Dr. Yan. “You can enter images; you could have it process audio; you can even start to have it refine video.”

To get started, he recommends signing up for a free account with ChatGPT, Gemini, Perplexity, Claude, and/or Microsoft Copilot. “To make the best choice, you have to try them out yourself because they each have their own kind of flavor and strengths and weaknesses,” said Dr. Yan.

Personally, he finds that ChatGPT is the most versatile, Gemini perhaps a little better in terms of image generation, and Perplexity probably the best at references because it was designed as an online library.

Once you figure out which platforms you prefer, consider signing up for a premium subscription, which is typically month to month and can be canceled at any time, Dr. Yan said. “This will allow you to get the most out of the AI model.”

As these AI systems are based on large language models, they are excellent at text, Dr. Yan noted. He suggests asking one to generate a letter or patient instruction sheet. “If you have a premium model, give it a PDF to summarize an article or take a photo of something that you want its opinion on.”

Privacy Critical

Always pay attention to privacy issues and avoid entering any private health information that would violate the Health Insurance Portability and Accountability Act (HIPAA), he said.

“We have to be very careful about how we interact with AI,” said Dr. Yan. “We can’t be posting private patient health information into these systems, no matter how useful these systems are.” Many academic institutions are creating “walled gardens” — private areas of AI access that don’t allow patient information to “leak out,” he said. “These AI models may have HIPAA protections in place and come with specific guidelines of use.”

The AI “scribe,” which helps with electronic health record documentation, is one of the most useful tools for clinicians, he said. He referred to a recent study showing that an AI scribe saved users an average of 1 hour at the keyboard every day, and a small patient survey showing 71% reported that it led to spending more time with their physician.

When entering requests into a prompt line with an AI system, Dr. Yan stressed that these prompts need to be clear and concise. For a complicated calculation or multistep problem, try adding the words “let’s do this step by step,” he said. “This is a technique invoking a ‘chain of thought’ that allows the system to enhance its accuracy when solving problems.”

If the response is not satisfactory, try being more detailed in the request, he advised, and consider giving the system examples of what you’re looking for and telling it what you don’t want in the output.

“For instance, if you’re asking for a differential diagnosis of rashes that affect the hands and feet, you can stipulate that you only want rashes that are vesicular or that arise in neonates, so you can get a more focused answer,” said Dr. Yan.

If there are “long-winded verbose” responses, add the phrase “be concise,” and it will shorten the response by about 50%, he added.
 

AI Hallucinations

Dr. Yan broached an issue that occasionally comes up, AI hallucinations, which refer to inaccurate or misleading responses on the basis of incomplete training or intrinsic biases within the model. He pointed to the case of a doctor discussing issues related to a patient’s hands, feet, and mouth, which the AI-generated model summarized as “the patient being diagnosed with hand, foot, and mouth disease.”

Another example he provided was a request to generate a letter of medical necessity for using ustekinumab (Stelara) for treating hidradenitis suppurative in a child that included references for its effectiveness and safety in children. The AI system generated “false references that sounded like they should be real because the authors are often people who have written in that field or on that subject,” said Dr. Yan.

When pressed, the system did acknowledge the references were hypothetical but were meant to illustrate the types of studies that would typically support the use of this drug in pediatric patients with HS. “ It’s well meaning, in the sense that it’s trying to help you achieve your goals using this training system,” said Dr. Yan.

“If you’re skeptical about a response, double-check the answer with a Google search or run the response through another AI [tool] asking it to check if the response is accurate,” he added.

While AI systems won’t replace the clinician, they are continuing to improve and becoming more sophisticated. Dr. Yan advises keeping up with emerging developments and engaging and adapting the most appropriate AI tool for an individual clinician’s work.

Asked to comment on the presentation at the SPD meeting, Sheilagh Maguiness, MD, director of the Division of Pediatric Dermatology at the University of Minnesota, Minneapolis, who, like other doctors, is increasingly testing AI, said she foresees a time when AI scribes fully replace humans for completing tasks during patient interactions.

“The hope is that if the AI scribes get good enough, we can just open our phone, have them translate the interaction, and create the notes for us.”

While she likes the idea of using ChatGPT to help with tasks like letters of recommendation for medications, Dr. Yan’s comments reiterated the importance of “checking and double-checking ChatGPT because it’s not correct all the time.” She particularly welcomed the advice “that we can just go back and ask it again to clarify, and that may improve its answers.”

Dr. Yan’s disclosures included an investment portfolio that includes companies working in the AI space, including Google, Apple, Nvidia, Amazon, Microsoft, and Arm. Dr. Maguiness had no relevant disclosures.

TORONTO — When it comes to using artificial intelligence (AI) in your practice, pediatric dermatologist Albert Yan, MD, professor of pediatrics and dermatology at the University of Pennsylvania, Philadelphia, suggests that dermatologists “just jump in” and become familiar with the various AI models.

He reminds doctors that many of their colleagues and patients and their families are already using these systems, “and you don’t want to be left behind.”

In an interview following his presentation on AI at the annual meeting of the Society for Pediatric Dermatology (SPD), Dr. Yan discussed his tips for using AI.
 

Changing Fast 

From the outset, most generative AI systems have been very good at processing language — for example, generating letters of medical necessity and summarizing disease processes into lay terms. But now they’re becoming “truly multimodal,” said Dr. Yan. “You can enter images; you could have it process audio; you can even start to have it refine video.”

To get started, he recommends signing up for a free account with ChatGPT, Gemini, Perplexity, Claude, and/or Microsoft Copilot. “To make the best choice, you have to try them out yourself because they each have their own kind of flavor and strengths and weaknesses,” said Dr. Yan.

Personally, he finds that ChatGPT is the most versatile, Gemini perhaps a little better in terms of image generation, and Perplexity probably the best at references because it was designed as an online library.

Potentially life-threatening cutaneous adverse drug reactions (cADRs) are associated with commonly prescribed oral antibiotics, according to a large, population-based, nested case-control study of older adults, spanning two decades.

The findings, published online in JAMA, “underscore the importance of judicious prescribing, with preferential use of antibiotics associated with a lower risk when clinically appropriate,” noted senior author David Juurlink, MD, PhD, professor of medicine; pediatrics; and health policy, management and evaluation at the University of Toronto, and head of the Clinical Pharmacology and Toxicology Division at Sunnybrook Health Sciences Centre, also in Toronto, Ontario, Canada, and coauthors.

“We hope our study raises awareness about the importance of drug allergy and gains support for future studies to improve drug allergy care,” lead author Erika Lee, MD, clinical immunology and allergy lecturer at the University of Toronto’s Drug Allergy Clinic, Sunnybrook Health Sciences Centre, said in an interview. “It is important to recognize symptoms and signs of a severe drug rash and promptly stop culprit drugs to prevent worsening reaction.”

Serious cADRs are “a group of rare but potentially life-threatening drug hypersensitivity reactions involving the skin and, frequently, internal organs,” the authors wrote. “Typically delayed in onset, these reactions include drug reaction with eosinophilia and systemic symptoms, Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN) — the most severe cADR, which has a reported mortality of 20%-40%,” they noted.

Speculation Without Data

Although it has been speculated that some oral antibiotics are more likely than others to be associated with serious cADRs, there have been no population-based studies examining this, they added.

The study included adults aged 66 years or older and used administrative health databases in Ontario, spanning from April 1, 2002, to March 31, 2022. Data on antibiotic use were taken from the Ontario Drug Benefit database. The Canadian Institute for Health Information (CIHI) National Ambulatory Care Reporting System was used to obtain data on emergency department (ED) visits for cADRs, while the CIHI Discharge Abstract Database was used to identify hospitalizations for cADRs. Finally, demographic information and outpatient healthcare utilization data were obtained from the Registered Persons Database and the Ontario Health Insurance Plan database, respectively.

A cohort of 21,758 older adults (median age, 75 years; 64.1% women) who had an ED visit or hospitalization for serious cADRs within 60 days of receiving antibiotic therapy was matched by age and sex with 87,025 antibiotic-treated controls who did not have a cutaneous reaction.

The median duration of antibiotic prescription was 7 days among cases and controls, and among the cases, the median latency period between antibiotic prescriptions and hospital visits for cADRs was 14 days. Most of the case patients went to the ED only (86.9%), and the rest were hospitalized.

The most commonly prescribed antibiotic class was penicillins (28.9%), followed by cephalosporins (18.2%), fluoroquinolones (16.5%), macrolides (14.8%), nitrofurantoin (8.6%), and sulfonamides (6.2%). Less commonly used antibiotics (“other” antibiotics) accounted for 6.9%.

Macrolide antibiotics were used as the reference because they are rarely associated with serious cADRs, noted the authors, and the multivariable analysis, adjusted for risk factors associated with serious cADRs, including malignancy, chronic liver disease, chronic kidney disease, and HIV.

After multivariable adjustment, relative to macrolides, sulfonamides were most strongly associated with serious cADRs (adjusted odds ratio [aOR], 2.9) but so were all other antibiotic classes, including cephalosporins (aOR, 2.6), “other” antibiotics (aOR, 2.3), nitrofurantoin (aOR, 2.2), penicillins (aOR, 1.4), and fluoroquinolones (aOR,1.3).

In the secondary analysis, the crude rate of ED visits or hospitalizations for cADRs was highest for cephalosporins (4.92 per 1000 prescriptions), followed by sulfonamides (3.22 per 1000 prescriptions). Among hospitalized patients, the median length of stay was 6 days, with 9.6% requiring transfer to a critical care unit and 5.3% dying in the hospital.
 

Hospitalizations, ED Visits Not Studied Previously

“Notably, the rate of antibiotic-associated serious cADRs leading to an ED visit or hospitalization has not been previously studied,” noted the authors. “We found that at least two hospital encounters for serious cADRs ensued for every 1000 antibiotic prescriptions. This rate is considerably higher than suggested by studies that examine only SJS/TEN and drug reaction with eosinophilia and systemic symptoms.”

Dr. Lee also emphasized the previously unreported findings about nitrofurantoin. “It is surprising to find that nitrofurantoin, a commonly prescribed antibiotic for urinary tract infection, is also associated with an increased risk of severe drug rash,” she said in an interview.

“This finding highlights a potential novel risk at a population-based level and should be further explored in other populations to verify this association,” the authors wrote.

Amesh Adalja, MD, a senior scholar at the Johns Hopkins Center for Health Security in Baltimore, Maryland, and a spokesperson for the Infectious Diseases Society of America, who was not involved in the study, agreed that the nitrofurantoin finding was surprising, but he was not surprised that sulfonamides were high on the list.

“The study reinforces that antibiotics are not benign medications to be dispensed injudiciously,” he said in an interview. “Antibiotics have risks, including serious skin reactions, as well as the fostering of antibiotic resistance. Clinicians should always first ask themselves if their patient actually merits an antibiotic and then assess what is the safest antibiotic for the purpose, bearing in mind that certain antibiotics are more likely to result in adverse reactions than others.”

The study was supported by the Canadian Institutes of Health Research. The study was conducted at ICES, which is funded in part by an annual grant from the Ontario Ministry of Health and Long-Term Care. One coauthor reported receiving compensation from the British Journal of Dermatology as reviewer and section editor, the American Academy of Dermatology as guidelines writer, Canadian Dermatology Today as manuscript writer, and the National Eczema Association and the Canadian Agency for Drugs and Technologies in Health as consultant; as well as receiving research grants to the coauthor’s institution from the National Eczema Association, Eczema Society of Canada, Canadian Dermatology Foundation, Canadian Institutes of Health Research, US National Institutes of Health, and PSI Foundation. Another coauthor reported receiving grants from AbbVie, Bausch Health, Celgene, Lilly, Incyte, Janssen, LEO Pharma, L’Oréal, Novartis, Organon, Pfizer, Sandoz, Amgen, and Boehringer Ingelheim; receiving payment or honoraria for speaking from Sanofi China; participating on advisory boards for LEO Pharma, Novartis, Sanofi, and Union Therapeutics; and receiving equipment donation from L’Oréal.

Among hospitalized patients, the median length of stay was 6 days, with 9.6% requiring transfer to a critical care unit and 5.3% dying in the hospital.
 

Hospitalizations, ED Visits Not Studied Previously

“Notably, the rate of antibiotic-associated serious cADRs leading to an ED visit or hospitalization has not been previously studied,” noted the authors. “We found that at least two hospital encounters for serious cADRs ensued for every 1000 antibiotic prescriptions. This rate is considerably higher than suggested by studies that examine only SJS/TEN and drug reaction with eosinophilia and systemic symptoms.”

Dr. Lee also emphasized the previously unreported findings about nitrofurantoin. “It is surprising to find that nitrofurantoin, a commonly prescribed antibiotic for urinary tract infection, is also associated with an increased risk of severe drug rash,” she said in an interview.

“This finding highlights a potential novel risk at a population-based level and should be further explored in other populations to verify this association,” the authors wrote.

Amesh Adalja, MD, a senior scholar at the Johns Hopkins Center for Health Security in Baltimore, Maryland, and a spokesperson for the Infectious Diseases Society of America, who was not involved in the study, agreed that the nitrofurantoin finding was surprising, but he was not surprised that sulfonamides were high on the list.

“The study reinforces that antibiotics are not benign medications to be dispensed injudiciously,” he said in an interview. “Antibiotics have risks, including serious skin reactions, as well as the fostering of antibiotic resistance. Clinicians should always first ask themselves if their patient actually merits an antibiotic and then assess what is the safest antibiotic for the purpose, bearing in mind that certain antibiotics are more likely to result in adverse reactions than others.”

The study was supported by the Canadian Institutes of Health Research. The study was conducted at ICES, which is funded in part by an annual grant from the Ontario Ministry of Health and Long-Term Care. One coauthor reported receiving compensation from the British Journal of Dermatology as reviewer and section editor, the American Academy of Dermatology as guidelines writer, Canadian Dermatology Today as manuscript writer, and the National Eczema Association and the Canadian Agency for Drugs and Technologies in Health as consultant; as well as receiving research grants to the coauthor’s institution from the National Eczema Association, Eczema Society of Canada, Canadian Dermatology Foundation, Canadian Institutes of Health Research, US National Institutes of Health, and PSI Foundation. Another coauthor reported receiving grants from AbbVie, Bausch Health, Celgene, Lilly, Incyte, Janssen, LEO Pharma, L’Oréal, Novartis, Organon, Pfizer, Sandoz, Amgen, and Boehringer Ingelheim; receiving payment or honoraria for speaking from Sanofi China; participating on advisory boards for LEO Pharma, Novartis, Sanofi, and Union Therapeutics; and receiving equipment donation from L’Oréal. Dr. Adalja reported no relevant disclosures.

Fevers? Vomiting? Fussiness? How to manage the first night home from the hospital? These are just a few of the hundreds of questions from parents that Atlanta, Georgia–based pediatric nurses Jennifer Walker and Laura Hunter answered well into the night.

A Folder, a Swaddle, and a Mission

Ms. Walker and Ms. Hunter literally wrote the book on helping people in the trenches of new parenthood. But it wasn’t quite a book at first. “It was a folder we printed off the computer with those questions coming in,” Ms. Hunter recalled. The nurses developed a way to approach each call with a specific outline of protocols they had designed.

“What if we just go to the [patient’s] house and help them figure that out?” Ms. Walker remembered one of the pediatricians she worked with suggesting in 2002. For example, Ms. Hunter’s swaddle technique that calmed even the fussiest babies worked much better if it was demonstrated in person.

The two embarked on home visits with new parents. But their advice would be practical, not medical. Because they were not classified as traveling nurses, they drew a “definitive line” that they wouldn’t be discussing “major medical issues.”

“Going into the homes here in Atlanta, taking that folder, clipping nails, doing baths, discussing feeding — whether you were doing bottles or breastfeeding — we were going to help parents where they were,” Ms. Hunter said.

The physicians they worked with began recommending their services. Ms. Walker jokes that they didn’t know what they were doing at first; they considered giving their first client their money back. But parents needed what they were delivering, which was advice, validation, and confidence in their parenting.

Just 6-8 weeks into their initiative, other practices started to inquire about whether the nurses could do the same thing for them.

It was a solution to the problem of the 15-minute office visit. “We were helping with those questions so that when [babies] came in for their well visits, those questions were already answered. Not only did we go into their homes, but we supported them in the months after we left,” Ms. Hunter said.
 

The Ripple Effect

The outcomes were astonishing. “Babies were sleeping through the night. Parents were more confident. We didn’t expect the results, and we were shocked at how consistent it was,” Ms. Walker said. “Laura and I used to call each other in disbelief after we would put these basic principles in place and partner with parents.”

Local pediatricians were grateful for the help. But for the nurses, it was about walking alongside families. The two have countless stories of desperate parents, marriages “on the brink of disaster,” moments when they realized their work was having a ripple effect.

One military family stands out in Ms. Walker’s memory. “The father was fighting for our country overseas, and his wife was struggling alone at home.”

But support from Moms on Call had a powerful impact. “When [the father] came home, he presented Laura with a flag and a beautiful personal note expressing his gratitude,” Ms. Walker said. “Once his wife had a partner to help and felt confident and well rested, his heart could rest as well. We did what he couldn’t, and it made all the difference. After all, that’s what he was fighting for in the first place.”
 

The Gambler Calls

After just 1 or 2 years as Moms on Call, Ms. Walker and Ms. Hunter got an unexpected call from none other than celebrity singer Kenny Rogers, who needed help with his twins.

“I was flipping through the folder, and he said: ‘It’s not copyrighted. It’ll be copyrighted tomorrow morning,’ ” Ms. Hunter recalled.

Mr. Rogers’ attorneys called the next day to provide all the information. “He said: ‘Y’all have got something here. Send this folder to a self-publishing company. Throw up a website. It’ll cost you a few thousand bucks,’” said Ms. Hunter. The business was officially born in 2004.

More of Mr. Rogers’ advice: “You can’t hit a bull’s-eye if you don’t throw a few darts. This is worth throwing a few darts at.”
 

‘They Don’t Teach You That in Nursing School’

The two nurses reimagined their all-knowing folder as a book with a DVD in the back. Because how do you teach parents how to suction noses without showing it? They also wanted to use an outline format — simpler for exhausted parents who just needed to get the information quickly. A few publishers pushed back on these ideas. But the nurses persisted and self-published the first edition.

The original website was basic. Ms. Walker’s Aunt Janet put it together. But grateful clients were Ms. Walker and Ms. Hunter’s best marketing tool, spreading the word to friends and family. The message: Parents know their own children best and can be empowered to help their own kids, rather than leaning on professionals alone.

A community of families also helped them navigate starting a business. A client who was a mergers and acquisitions lawyer helped them form their LLC. “They don’t teach you that in nursing school,” Ms. Walker said. 

Ms. Walker added that they made mistakes. “Not everyone that we encountered viewed or felt the same way about growing a business that is primarily focused on helping families. Sometimes that meant offering services at no charge. Or saying no to certain partnerships that didn’t align with our business model.”

Ms. Walker and Ms. Hunter had an eye on equity in creating multiple ways to access their advice at various price points. They started by charging around $75 for an in-home visit. (Now, if one of the CEOs comes out, it’s around $1000.) But the books, app, and online resources support those who can’t access that, as do an additional 10 in-home consultants around the country.

Along the way, moments told them they were going in the right direction and helped them define their purpose. “It is having a client ‘buy’ us as their go-to [baby] shower gift. It is being able to provide and support a clinic in Kenya or military families around the world. It is helping families realize that they can sleep — that they aren’t alone,” Ms. Walker said. 
 

On Call 24/7 in the Car, in the Checkout Line ...

The early days of Moms on Call were also a juggling act. As Ms. Walker and Ms. Hunter balanced work and home with 10 of their own kids between the two of them, they took calls wherever they were. A friend and caller once joked that she could tell Ms. Hunter was checking out at the grocery store while she advised her on her very sick son’s vomiting.

“We were still trying to take care of the kids, run the house, and neither one of us had nannies or night nurses or housekeepers,” Ms. Hunter said. “But being on call allowed us to still be at home.”

Ms. Walker remembers taking calls on the way to ball games with her own kids, who by 8 years old could recite the advice for a baby’s fever from the back of the car. “It was like a family affair, and our kids got to see how that works and see their moms in action,” she said.

Through it all, Ms. Walker and Ms. Hunter’s motivation came from knowing that thousands of parents were begging for help — and they had an answer.

“Our shoulders have absorbed so many tears of parents who were exhausted and hurting, some who had been lied to or told their child would never sleep or had to be raised a certain way. When someone steals that confidence, especially from a brand-new parent overwhelmed by information, it makes us want to shout the truth from every rooftop and digital channel available,” Ms. Walker added.
 

Do You Have a Business Idea?

“Boots on the ground” healthcare professionals often see new opportunities to serve patients who might be falling through the cracks of the healthcare system. While not all will become a full-blown business, Ms. Hunter encourages them to break down their idea into “bite-sized pieces.” Just have the next conversation.

“Ask the people around you and the people who are brought to you,” Ms. Hunter said. When the two nurses look back, they see how those pieces of the puzzle were meant to come together. “Ask everyone you know,” Ms. Hunter advised. “And talk to the people you are taking care of. It’s possible they have a gift that will help you get to the next bite-sized piece.”

In short — develop a network of people who believe in your idea. Prioritize those relationships and see where they can take you.

The close relationship between Ms. Walker and Ms. Hunter, as business partners and friends, has also been crucial. They joke that they finish each other’s sentences and sandwiches. “You have to fight for that — we prioritize [that relationship]” too, Ms. Walker said.

Finally, remember why you are doing what you do, Ms. Walker said. “These are the people we help: Wonderful people with jobs that serve us all — the airplane pilot, the anesthesiologist, the pediatrician, the single dad. They are all parents who have felt alone and exhausted. In those lonely moments of a parent’s heart where they fear they are doing the wrong thing, we want to be the voice of hope,” she added. “We let them know that if they ever wondered if they were doing it right, well, only good parents wonder that.”

The American Headache Society (AHS) has published a white paper guiding the treatment of posttraumatic headache caused by concussion in youth.

The guidance document, the first of its kind, covers risk factors for prolonged recovery, along with pharmacologic and nonpharmacologic management strategies, and supports an emphasis on multidisciplinary care, lead author Carlyn Patterson Gentile, MD, PhD, attending physician in the Division of Neurology at Children’s Hospital of Philadelphia in Pennsylvania, and colleagues reported.

“There are no guidelines to inform the management of posttraumatic headache in youth, but multiple studies have been conducted over the past 2 decades,” the authors wrote in Headache. “This white paper aims to provide a thorough review of the current literature, identify gaps in knowledge, and provide a road map for [posttraumatic headache] management in youth based on available evidence and expert opinion.”
 

Clarity for an Underrecognized Issue

According to Russell Lonser, MD, professor and chair of neurological surgery at Ohio State University, Columbus, the white paper is important because it offers concrete guidance for health care providers who may be less familiar with posttraumatic headache in youth.

“It brings together all of the previous literature ... in a very well-written way,” Dr. Lonser said in an interview. “More than anything, it could reassure [providers] that they shouldn’t be hunting down potentially magical cures, and reassure them in symptomatic management.”

Meeryo C. Choe, MD, associate clinical professor of pediatric neurology at UCLA Health in Calabasas, California, said the paper also helps shine a light on what may be a more common condition than the public suspects.

“While the media focuses on the effects of concussion in professional sports athletes, the biggest population of athletes is in our youth population,” Dr. Choe said in a written comment. “Almost 25 million children participate in sports throughout the country, and yet we lack guidelines on how to treat posttraumatic headache which can often develop into persistent postconcussive symptoms.”

This white paper, she noted, builds on Dr. Gentile’s 2021 systematic review, introduces new management recommendations, and aligns with the latest consensus statement from the Concussion in Sport Group.

Risk Factors

The white paper first emphasizes the importance of early identification of youth at high risk for prolonged recovery from posttraumatic headache. Risk factors include female sex, adolescent age, a high number of acute symptoms following the initial injury, and social determinants of health.

“I agree that it is important to identify these patients early to improve the recovery trajectory,” Dr. Choe said.

Identifying these individuals quickly allows for timely intervention with both pharmacologic and nonpharmacologic therapies, Dr. Gentile and colleagues noted, potentially mitigating persistent symptoms. Clinicians are encouraged to perform thorough initial assessments to identify these risk factors and initiate early, personalized management plans.

Initial Management of Acute Posttraumatic Headache

For the initial management of acute posttraumatic headache, the white paper recommends a scheduled dosing regimen of simple analgesics. Ibuprofen at a dosage of 10 mg/kg every 6-8 hours (up to a maximum of 600 mg per dose) combined with acetaminophen has shown the best evidence for efficacy. Provided the patient is clinically stable, this regimen should be initiated within 48 hours of the injury and maintained with scheduled dosing for 3-10 days.

If effective, these medications can subsequently be used on an as-needed basis. Careful usage of analgesics is crucial, the white paper cautions, as overadministration can lead to medication-overuse headaches, complicating the recovery process.

Secondary Treatment Options

In cases where first-line oral medications are ineffective, the AHS white paper outlines several secondary treatment options. These include acute intravenous therapies such as ketorolac, dopamine receptor antagonists, and intravenous fluids. Nerve blocks and oral corticosteroid bridges may also be considered.

The white paper stresses the importance of individualized treatment plans that consider the specific needs and responses of each patient, noting that the evidence supporting these approaches is primarily derived from retrospective studies and case reports.

“Patient preferences should be factored in,” said Sean Rose, MD, pediatric neurologist and codirector of the Complex Concussion Clinic at Nationwide Children’s Hospital, Columbus, Ohio.

Supplements and Preventive Measures

For adolescents and young adults at high risk of prolonged posttraumatic headache, the white paper suggests the use of riboflavin and magnesium supplements. Small randomized clinical trials suggest that these supplements may aid in speeding recovery when administered for 1-2 weeks within 48 hours of injury.

If significant headache persists after 2 weeks, a regimen of riboflavin 400 mg daily and magnesium 400-500 mg nightly can be trialed for 6-8 weeks, in line with recommendations for migraine prevention. Additionally, melatonin at a dose of 3-5 mg nightly for an 8-week course may be considered for patients experiencing comorbid sleep disturbances.

Targeted Preventative Therapy

The white paper emphasizes the importance of targeting preventative therapy to the primary headache phenotype.

For instance, patients presenting with a migraine phenotype, or those with a personal or family history of migraines, may be most likely to respond to medications proven effective in migraine prevention, such as amitriptyline, topiramate, and propranolol.

“Most research evidence [for treating posttraumatic headache in youth] is still based on the treatment of migraine,” Dr. Rose pointed out in a written comment.

Dr. Gentile and colleagues recommend initiating preventive therapies 4-6 weeks post injury if headaches are not improving, occur more than 1-2 days per week, or significantly impact daily functioning.

Specialist Referrals and Physical Activity

Referral to a headache specialist is advised for patients who do not respond to first-line acute and preventive therapies. Specialists can offer advanced diagnostic and therapeutic options, the authors noted, ensuring a comprehensive approach to managing posttraumatic headache.

The white paper also recommends noncontact, sub–symptom threshold aerobic physical activity and activities of daily living after an initial 24-48 hour period of symptom-limited cognitive and physical rest. Engaging in these activities may promote faster recovery and help patients gradually return to their normal routines.

“This has been a shift in the concussion treatment approach over the last decade, and is one of the most important interventions we can recommend as physicians,” Dr. Choe noted. “This is where pediatricians and emergency department physicians seeing children acutely can really make a difference in the recovery trajectory for a child after a concussion. ‘Cocoon therapy’ has been proven not only to not work, but be detrimental to recovery.”
 

Nonpharmacologic Interventions

Based on clinical assessment, nonpharmacologic interventions may also be considered, according to the white paper. These interventions include cervico-vestibular therapy, which addresses neck and balance issues, and cognitive-behavioral therapy, which helps manage the psychological aspects of chronic headache. Dr. Gentile and colleagues highlighted the potential benefits of a collaborative care model that incorporates these nonpharmacologic interventions alongside pharmacologic treatments, providing a holistic approach to posttraumatic headache management.

“Persisting headaches after concussion are often driven by multiple factors,” Dr. Rose said. “Multidisciplinary concussion clinics can offer multiple treatment approaches such as behavioral, physical therapy, exercise, and medication options.”
 

Unmet Needs

The white paper concludes by calling for high-quality prospective cohort studies and placebo-controlled, randomized, controlled trials to further advance the understanding and treatment of posttraumatic headache in children.

Dr. Lonser, Dr. Choe, and Dr. Rose all agreed.

“More focused treatment trials are needed to gauge efficacy in children with headache after concussion,” Dr. Rose said.

Specifically, Dr. Gentile and colleagues underscored the need to standardize data collection via common elements, which could improve the ability to compare results across studies and develop more effective treatments. In addition, research into the underlying pathophysiology of posttraumatic headache is crucial for identifying new therapeutic targets and clinical and biological markers that can personalize patient care.

They also stressed the importance of exploring the impact of health disparities and social determinants on posttraumatic headache outcomes, aiming to develop interventions that are equitable and accessible to all patient populations.The white paper was approved by the AHS, and supported by the National Institutes of Health/National Institute of Neurological Disorders and Stroke K23 NS124986. The authors disclosed relationships with Eli Lilly, Pfizer, Amgen, and others. The interviewees disclosed no conflicts of interest.

The American Headache Society (AHS) has published a white paper guiding the treatment of posttraumatic headache caused by concussion in youth.

The guidance document, the first of its kind, covers risk factors for prolonged recovery, along with pharmacologic and nonpharmacologic management strategies, and supports an emphasis on multidisciplinary care, lead author Carlyn Patterson Gentile, MD, PhD, attending physician in the Division of Neurology at Children’s Hospital of Philadelphia in Pennsylvania, and colleagues reported.

“There are no guidelines to inform the management of posttraumatic headache in youth, but multiple studies have been conducted over the past 2 decades,” the authors wrote in Headache. “This white paper aims to provide a thorough review of the current literature, identify gaps in knowledge, and provide a road map for [posttraumatic headache] management in youth based on available evidence and expert opinion.”
 

Clarity for an Underrecognized Issue

According to Russell Lonser, MD, professor and chair of neurological surgery at Ohio State University, Columbus, the white paper is important because it offers concrete guidance for health care providers who may be less familiar with posttraumatic headache in youth.

“It brings together all of the previous literature ... in a very well-written way,” Dr. Lonser said in an interview. “More than anything, it could reassure [providers] that they shouldn’t be hunting down potentially magical cures, and reassure them in symptomatic management.”

Meeryo C. Choe, MD, associate clinical professor of pediatric neurology at UCLA Health in Calabasas, California, said the paper also helps shine a light on what may be a more common condition than the public suspects.

“While the media focuses on the effects of concussion in professional sports athletes, the biggest population of athletes is in our youth population,” Dr. Choe said in a written comment. “Almost 25 million children participate in sports throughout the country, and yet we lack guidelines on how to treat posttraumatic headache which can often develop into persistent postconcussive symptoms.”

This white paper, she noted, builds on Dr. Gentile’s 2021 systematic review, introduces new management recommendations, and aligns with the latest consensus statement from the Concussion in Sport Group.

Risk Factors

The white paper first emphasizes the importance of early identification of youth at high risk for prolonged recovery from posttraumatic headache. Risk factors include female sex, adolescent age, a high number of acute symptoms following the initial injury, and social determinants of health.

“I agree that it is important to identify these patients early to improve the recovery trajectory,” Dr. Choe said.

Identifying these individuals quickly allows for timely intervention with both pharmacologic and nonpharmacologic therapies, Dr. Gentile and colleagues noted, potentially mitigating persistent symptoms. Clinicians are encouraged to perform thorough initial assessments to identify these risk factors and initiate early, personalized management plans.

Initial Management of Acute Posttraumatic Headache

For the initial management of acute posttraumatic headache, the white paper recommends a scheduled dosing regimen of simple analgesics. Ibuprofen at a dosage of 10 mg/kg every 6-8 hours (up to a maximum of 600 mg per dose) combined with acetaminophen has shown the best evidence for efficacy. Provided the patient is clinically stable, this regimen should be initiated within 48 hours of the injury and maintained with scheduled dosing for 3-10 days.

If effective, these medications can subsequently be used on an as-needed basis. Careful usage of analgesics is crucial, the white paper cautions, as overadministration can lead to medication-overuse headaches, complicating the recovery process.

Secondary Treatment Options

In cases where first-line oral medications are ineffective, the AHS white paper outlines several secondary treatment options. These include acute intravenous therapies such as ketorolac, dopamine receptor antagonists, and intravenous fluids. Nerve blocks and oral corticosteroid bridges may also be considered.

The white paper stresses the importance of individualized treatment plans that consider the specific needs and responses of each patient, noting that the evidence supporting these approaches is primarily derived from retrospective studies and case reports.

A new consensus statement recommended genetic testing for all categories of kidney diseases whenever a genetic cause is suspected and offered guidance on who to test, which tests are the most useful, and how to talk to patients about results.

The statement, published online in the American Journal of Kidney Diseases, is the work of four dozen authors — including patients, nephrologists, experts in clinical and laboratory genetics, kidney pathology, genetic counseling, and ethics. The experts were brought together by the National Kidney Foundation (NKF) with the goal of broadening use and understanding of the tests.

About 10% or more of kidney diseases in adults and 70% of selected chronic kidney diseases (CKDs) in children have genetic causes. But nephrologists have reported a lack of education about genetic testing, and other barriers to wider use, including limited access to testing, cost, insurance coverage, and a small number of genetic counselors who are versed in kidney genetics.

Genetic testing “in the kidney field is a little less developed than in other fields,” said co–lead author Nora Franceschini, MD, MPH, a professor of epidemiology at the University of North Carolina Gillings School of Global Public Health, Chapel Hill, and a nephrologist who studies the genetic epidemiology of hypertension and kidney and cardiovascular diseases.

There are already many known variants that play a role in various kidney diseases and more are on the horizon, Dr. Franceschini told this news organization. More genetic tests will be available in the near future. “The workforce needs to be prepared,” she said.

The statement is an initial step that gets clinicians thinking about testing in a more systematic way, said Dr. Franceschini. “Genetic testing is just another test that physicians can use to complete the story when evaluating patients.

“I think clinicians are ready to implement” testing, said Dr. Franceschini. “We just need to have better guidance.”
 

Who, When, What to Test

The NKF statement is not the first to try to address gaps in use and knowledge. A European Renal Association Working Group published guidelines in 2022.

The NKF Working Group came up with 56 recommendations and separate algorithms to guide testing for adult and pediatric individuals who are considered at-risk (and currently asymptomatic) and for those who already have clinical disease.

Testing can help determine a cause if there’s an atypical clinical presentation, and it can help avoid biopsies, said the group. Tests can also guide choice of therapy.

For at-risk individuals, there are two broad situations in which testing might be considered: In family members of a patient who already has kidney disease and in potential kidney donors. But testing at-risk children younger than 18 years should only be done if there is an intervention available that could prevent, treat, or slow progression of disease, said the authors.

For patients with an established genetic diagnosis, at-risk family members should be tested with the known single-gene variant diagnostic instead of a broad panel, said the group.

Single-gene variant testing is most appropriate in situations when clinical disease is already evident or when there is known genetic disease in the family, according to the NKF panel. A large diagnostic panel that covers the many common genetic causes of kidney disease is recommended for the majority of patients.

The group recommended that apolipoprotein L1 (APOL1) testing should be included in gene panels for CKD, and it should be offered to any patient “with clinical findings suggestive of APOL1-association nephropathy, regardless of race and ethnicity.”

High-risk APOL1 genotypes confer a 5- to 10-fold increased risk for CKD and are found in one out of seven individuals of African ancestry, which means the focus has largely been on testing those with that ancestry.

However, with many unknowns about APOL1, the NKF panel did not want to “profile” individuals and suggest that testing should not be based on skin color or race/ethnicity, said Dr. Franceschini.

In addition, only about 10% of those with the variant develop disease, so testing is not currently warranted for those who do not already have kidney disease, said the group.

They also recommended against the use of polygenic risk scores, saying that there are not enough data from diverse populations in genome-wide association studies for kidney disease or on their clinical utility.
 

More Education Needed; Many Barriers

The authors acknowledged that nephrologists generally receive little education in genetics and lack support for interpreting and discussing results.

“Nephrologists should be provided with training and best practice resources to interpret genetic testing and discuss the results with individuals and their families,” they wrote, adding that there’s a need for genomic medicine boards at academic centers that would be available to help nephrologists interpret results and plot clinical management.

The group did not, however, cite some of the other barriers to adoption of testing, including a limited number of sites offering testing, cost, and lack of insurance coverage for the diagnostics.

Medicare may cover genetic testing for kidney disease when an individual has symptoms and there is a Food and Drug Administration–approved test. Joseph Vassalotti, MD, chief medical officer for the NKF, said private insurance may cover the testing if the nephrologist deems it medically necessary, but that he usually confirms coverage before initiating testing. The often-used Renasight panel, which tests for 385 genes related to kidney diseases, costs $300-$400 out of pocket, Dr. Vassalotti told this news organization.

In a survey of 149 nephrologists conducted in 2021, both users (46%) and nonusers of the tests (69%) said that high cost was the most significant perceived barrier to implementing widespread testing. A third of users and almost two thirds of nonusers said that poor availability or lack of ease of testing was the second most significant barrier.

Clinics that test for kidney genes “are largely confined to large academic centers and some specialty clinics,” said Dominic Raj, MD, the Bert B. Brooks chair, and Divya Shankaranarayanan, MD, director of the Kidney Precision Medicine Clinic, both at George Washington University School of Medicine & Health Sciences, Washington, DC, in an email.

Testing is also limited by cultural barriers, lack of genetic literacy, and patients’ concerns that a positive result could lead to a loss of health insurance coverage, said Dr. Raj and Dr. Shankaranarayanan.
 

Paper Will Help Expand Use

A lack of consensus has also held back expansion. The new statement “may lead to increased and possibly judicious utilization of genetic testing in nephrology practices,” said Dr. Raj and Dr. Shankaranarayanan. “Most importantly, the panel has given specific guidance as to what type of genetic test platform is likely to yield the best and most cost-effective yield.”

The most effective use is “in monogenic kidney diseases and to a lesser extent in oligogenic kidney disease,” said Dr. Raj and Dr. Shankaranarayanan, adding that testing is of less-certain utility in polygenic kidney diseases, “where complex genetic and epigenetic factors determine the phenotype.”

Genetic testing might be especially useful “in atypical clinical presentations” and can help clinicians avoid unnecessary expensive and extensive investigations when multiple organ systems are involved, they said.

“Most importantly, [testing] might prevent unnecessary and potentially harmful treatment and enable targeted specific treatment, when available,” said Dr. Raj and Dr. Shankaranarayanan.

Dr. Franceschini and Dr. Shankaranarayanan reported no relevant financial relationships. Dr. Raj disclosed that he received consulting fees and honoraria from Novo Nordisk and is a national leader for the company’s Zeus trial, studying whether ziltivekimab reduces the risk for cardiovascular events in cardiovascular disease, CKD, and inflammation. He also participated in a study of Natera’s Renasight, a 385-gene panel for kidney disease.

The statement, published online in the American Journal of Kidney Diseases, is the work of four dozen authors — including patients, nephrologists, experts in clinical and laboratory genetics, kidney pathology, genetic counseling, and ethics. The experts were brought together by the National Kidney Foundation (NKF) with the goal of broadening use and understanding of the tests.

About 10% or more of kidney diseases in adults and 70% of selected chronic kidney diseases (CKDs) in children have genetic causes. But nephrologists have reported a lack of education about genetic testing, and other barriers to wider use, including limited access to testing, cost, insurance coverage, and a small number of genetic counselors who are versed in kidney genetics.

Genetic testing “in the kidney field is a little less developed than in other fields,” said co–lead author Nora Franceschini, MD, MPH, a professor of epidemiology at the University of North Carolina Gillings School of Global Public Health, Chapel Hill, and a nephrologist who studies the genetic epidemiology of hypertension and kidney and cardiovascular diseases.

There are already many known variants that play a role in various kidney diseases and more are on the horizon, Dr. Franceschini told this news organization. More genetic tests will be available in the near future. “The workforce needs to be prepared,” she said.

The statement is an initial step that gets clinicians thinking about testing in a more systematic way, said Dr. Franceschini. “Genetic testing is just another test that physicians can use to complete the story when evaluating patients.

“I think clinicians are ready to implement” testing, said Dr. Franceschini. “We just need to have better guidance.”
 

Who, When, What to Test

The NKF statement is not the first to try to address gaps in use and knowledge. A European Renal Association Working Group published guidelines in 2022.

The NKF Working Group came up with 56 recommendations and separate algorithms to guide testing for adult and pediatric individuals who are considered at-risk (and currently asymptomatic) and for those who already have clinical disease.

Testing can help determine a cause if there’s an atypical clinical presentation, and it can help avoid biopsies, said the group. Tests can also guide choice of therapy.

For at-risk individuals, there are two broad situations in which testing might be considered: In family members of a patient who already has kidney disease and in potential kidney donors. But testing at-risk children younger than 18 years should only be done if there is an intervention available that could prevent, treat, or slow progression of disease, said the authors.

For patients with an established genetic diagnosis, at-risk family members should be tested with the known single-gene variant diagnostic instead of a broad panel, said the group.

Single-gene variant testing is most appropriate in situations when clinical disease is already evident or when there is known genetic disease in the family, according to the NKF panel. A large diagnostic panel that covers the many common genetic causes of kidney disease is recommended for the majority of patients.

The group recommended that apolipoprotein L1 (APOL1) testing should be included in gene panels for CKD, and it should be offered to any patient “with clinical findings suggestive of APOL1-association nephropathy, regardless of race and ethnicity.”

High-risk APOL1 genotypes confer a 5- to 10-fold increased risk for CKD and are found in one out of seven individuals of African ancestry, which means the focus has largely been on testing those with that ancestry.

However, with many unknowns about APOL1, the NKF panel did not want to “profile” individuals and suggest that testing should not be based on skin color or race/ethnicity, said Dr. Franceschini.

In addition, only about 10% of those with the variant develop disease, so testing is not currently warranted for those who do not already have kidney disease, said the group.

They also recommended against the use of polygenic risk scores, saying that there are not enough data from diverse populations in genome-wide association studies for kidney disease or on their clinical utility.
 

More Education Needed; Many Barriers

The authors acknowledged that nephrologists generally receive little education in genetics and lack support for interpreting and discussing results.

“Nephrologists should be provided with training and best practice resources to interpret genetic testing and discuss the results with individuals and their families,” they wrote, adding that there’s a need for genomic medicine boards at academic centers that would be available to help nephrologists interpret results and plot clinical management.

The group did not, however, cite some of the other barriers to adoption of testing, including a limited number of sites offering testing, cost, and lack of insurance coverage for the diagnostics.

Medicare may cover genetic testing for kidney disease when an individual has symptoms and there is a Food and Drug Administration–approved test. Joseph Vassalotti, MD, chief medical officer for the NKF, said private insurance may cover the testing if the nephrologist deems it medically necessary, but that he usually confirms coverage before initiating testing. The often-used Renasight panel, which tests for 385 genes related to kidney diseases, costs $300-$400 out of pocket, Dr. Vassalotti told this news organization.

In a survey of 149 nephrologists conducted in 2021, both users (46%) and nonusers of the tests (69%) said that high cost was the most significant perceived barrier to implementing widespread testing. A third of users and almost two thirds of nonusers said that poor availability or lack of ease of testing was the second most significant barrier.

Clinics that test for kidney genes “are largely confined to large academic centers and some specialty clinics,” said Dominic Raj, MD, the Bert B. Brooks chair, and Divya Shankaranarayanan, MD, director of the Kidney Precision Medicine Clinic, both at George Washington University School of Medicine & Health Sciences, Washington, DC, in an email.

Testing is also limited by cultural barriers, lack of genetic literacy, and patients’ concerns that a positive result could lead to a loss of health insurance coverage, said Dr. Raj and Dr. Shankaranarayanan.
 

Paper Will Help Expand Use

A lack of consensus has also held back expansion. The new statement “may lead to increased and possibly judicious utilization of genetic testing in nephrology practices,” said Dr. Raj and Dr. Shankaranarayanan. “Most importantly, the panel has given specific guidance as to what type of genetic test platform is likely to yield the best and most cost-effective yield.”

The most effective use is “in monogenic kidney diseases and to a lesser extent in oligogenic kidney disease,” said Dr. Raj and Dr. Shankaranarayanan, adding that testing is of less-certain utility in polygenic kidney diseases, “where complex genetic and epigenetic factors determine the phenotype.”

Genetic testing might be especially useful “in atypical clinical presentations” and can help clinicians avoid unnecessary expensive and extensive investigations when multiple organ systems are involved, they said.

“Most importantly, [testing] might prevent unnecessary and potentially harmful treatment and enable targeted specific treatment, when available,” said Dr. Raj and Dr. Shankaranarayanan.

Dr. Franceschini and Dr. Shankaranarayanan reported no relevant financial relationships. Dr. Raj disclosed that he received consulting fees and honoraria from Novo Nordisk and is a national leader for the company’s Zeus trial, studying whether ziltivekimab reduces the risk for cardiovascular events in cardiovascular disease, CKD, and inflammation. He also participated in a study of Natera’s Renasight, a 385-gene panel for kidney disease.
