A large study of adolescent soccer players in Michigan revealed key differences in concussion injury metrics among males and females, underscoring a need to develop sex-specific approaches to managing injury in the sport.

Sport-related concussion (SRC) is a specific concern in young female athletes, study authors Abigail C. Bretzin, PhD, and colleagues noted in their paper, which appears in JAMA Network Open. Previous surveillance studies on SRC at the high school and college level have reported higher rates of injury risk and longer recovery outcomes in female soccer athletes. Taking a deeper dive into these trends, the investigators explored whether sex-associated differences existed in SRC, addressing the mechanics, management, and recovery from SRC.

“This is an area that is remarkably underresearched,” William Stewart, MBChB, PhD, the study’s corresponding author, said in an interview. Prior studies of males and females have shown that female axons are thinner, with fewer microtubules or internal scaffolding than male axons. This potentially increases risk of shear injury in females. Limited research has also cited differences in concussion risk across the menstrual cycle in female athletes.
 

Reporting system targets four injury areas

The investigators conducted a high school injury surveillance project in 43,741 male and 39,637 female soccer athletes participating in the Michigan High School Athletic Association (MHSAA) Head Injury Reporting System. The study included students from 9th to 12th grade, spanning from the beginning of academic year 2016-2017 to the end of academic year 2018-2019. Since 2015, the state has mandated high schools to submit data to MHSAA.

MHSAA captures data on four categories: person-to-person contact, person-to-object contact, person-to-playing surface contact, or uncertain about cause of the event. Study outcomes included details regarding injury mechanism, immediate management, and return-to-play time for each documented SRC.

Investigators reported notable differences among male and female players. Documented SRC risk was 1.88 times higher among adolescent girls than boys across all academic years (RR, 1.88; 95% CI, 1.69-2.09; P < .001). They also cited inconsistencies in distribution of injury mechanisms among the sexes. Females were most likely to suffer injury from equipment contact such as heading a ball (41.9%), whereas male players commonly sustained SRC from contact with another player (48.4%). The authors suggested that “female soccer athletes have lower neck strength and girth, compared with male athletes, with these variables inversely associated with linear and rotational head acceleration after soccer ball heading.”

Boys had greater odds of immediate removal from play and but also returned to the sport 2 days sooner than girls. “The possibility exists, therefore, that this longer recovery time might, in part, be reflective of our observed differences in immediate care, in particular removal from play,” the authors wrote. Immediate removal from play was also more common in cases where an athletic trainer played a part in evaluating players for SRC.
 

Eliminating the one-size-fits-all approach

Current concussion management is based on a “one-size-fits-all” model, said Dr. Stewart. Male and female athletes are treated following a common concussion management protocol, covering concussion detection through to rehabilitation. “This model of management is based on research that is almost exclusively in male athletes.”

What the study showed is this one-size-fits-all approach may be flawed, letting down female athletes. “We should be pursuing more research in sex differences in concussion and, importantly, putting these into practice in sex-specific concussion management protocols,” he suggested.

Future studies should also look at the effects of athletic trainer employment on SRC metrics. “Although this was a large, statewide epidemiological study of reported SRC in adolescent soccer athletes, inclusive of high schools with and without access to athletic trainers, the Head Injury Reporting System did not include information on the whether there were athletic trainer services available at each school, including specific athletic training services for soccer,” wrote the investigators, in citing the study’s limitations.
 

Girls report symptoms more often

“The researchers are to be commended for taking a prospective approach to address this common observation in high school sports,” said Keith J. Loud, MD, MSc, FAAP, a sports pediatrician at Children’s Hospital at Dartmouth-Hitchcock in Manchester, N.H. The results are “entirely believable,” said Dr. Loud, who was not affiliated with the study. “We have long postulated differences in neurophysiology, neck strength, style of play, and tendency to report as explanations for the observation that girls in high school soccer are diagnosed with more concussions than boys.”

The findings suggest that boys play more aggressively, but sustain fewer concussions, he added. Girls in the meantime, are more likely to speak up about their injury.

“Concussion diagnosis still relies to a large degree on the athlete to report symptoms, which is one of our hypotheses as to why girls seem to sustain more concussions – they report symptoms more often. That could also be why they have a prolonged recovery,” offered Dr. Loud. A main limitation of this study is it can’t overcome this reporting bias.

Dr. Loud was also concerned that girls were less likely to be removed from game play, even though they apparently sustained more concussions. “Perhaps that is because their injuries are less obvious on the field, and they are diagnosed when reported after the games.”

Dr. Stewart reported receiving grants from The Football Association and National Health Service Research Scotland during the study. He also served as a nonremunerated member of the Fédération Internationale de Football Association Independent Football Concussion Advisory Group and the Football Association Expert Panel on Concussion and Head Injury in Football. None of the other authors had disclosures.

What started as an attempt to standardize care for acute myocardial infarction with cardiogenic shock at a handful of Detroit-area hospitals has led to markedly better survival rates than the traditional flip of a coin, in a nationwide analysis.

Final results from the National Cardiogenic Shock Initiative (NCSI) show 71% of patients survived to discharge and 68% were alive at 30 days.

Patients presenting in stage C or D shock, who comprised the bulk of patients in previous trials, had survival rates of 79% and 77%, respectively.

Among stage E patients, who are in extremis and have typical survival rates of less than 20%, survival was 54% at discharge and 49% at 30 days, co–principal investigator Babar Basir, DO, Henry Ford Hospital, Detroit, reported at the Society for Cardiovascular Angiography and Interventions (SCAI) annual scientific sessions, held virtually.

“This is the first push to really be able to consistently get survival rates over 50%, particularly in those patients who presented in stage C and D shock,” he said. “Really, it’s important to emphasize here the hard work it’s taken to get to this point and all the research that’s been done.”

The NCSI protocol emphasizes rapid identification and support of cardiogenic shock (door to support time <90 minutes), early placement of the Impella (Abiomed) ventricular assist device prior to percutaneous coronary intervention (PCI), and right heart monitoring to reduce the use of inotropes and vasopressors.

Co–principal investigator William O’Neill, MD, also from Henry Ford, previously reported results from the pilot study showing 84% of 30 patients survived to discharge.

The present analysis was based on outcomes of 406 consecutive acute MI patients (mean age, 63.7 years; 24% female) who presented with cardiogenic shock at 32 academic and 48 community hospitals in 29 states and the District of Columbia.

Dr. Basir emphasized that this is the largest prospective North American acute MI cardiogenic shock study in 20 years and recruited “one of the sickest cohorts ever studied.” The average blood pressure among the patients was 77/50 mm Hg; 77% had a lactate of at least 2 mmol/L (mean, 4.8 mmol/L), and 25% were in stage E shock.

One-quarter of patients were transferred from other institutions, 82% presented with ST-segment elevation MI, two-thirds had multivessel disease, and 13% had a left main culprit lesion.

Right heart catheterization was used in 90% of patients, an Impella CP device in 92%, an Impella 2.5 device in 5%, femoral access PCI in 78%, and aspiration thrombectomy in a full 27%.

Despite this sick cohort, survival at 30 days was better than in any previous study of cardiogenic shock, Dr. Basir said. In comparison, 30-day survival rates were 53%, 60%, and 49% in the SHOCK, IABP SHOCK, and CULPRIT SHOCK trials, respectively.

That said, survival over the course of the first year fell to 53% in the entire cohort, 62% in patients with stage C or D shock, and 31% in those in stage E shock.

“One-year mortality continues to be a problem for these patients and emphasizes the need for goal-directed medical therapy, early advanced heart failure follow-up, and novel therapies such as what we are planning with the evaluation of [supersaturated oxygen] SSO₂ to reduce infarct sizes in the ISO-SHOCK trial,” set to begin later this year, Dr. Basir said.

Given the promising results in the NCSI, the randomized controlled RECOVER IV trial is planned to begin in 2022, he noted. It will assess whether Impella pre-PCI is superior to PCI without Impella in patients with inclusion criteria similar to that of the NCSI. The DanGer Shock randomized trial is ongoing in Denmark and Germany and assessing all-cause mortality at 6 months with the Impella CP device compared with standard of care.

“We hypothesize that greater utilization of this protocol, and refinement of the escalation strategies will consistently lead to a survival rate greater than 80%,” Dr. Basir concluded.

Past SCAI president Kirk Garratt, MD, Christiana Care, Newark, Del., who moderated a press conference where the data were highlighted, noted that late complications led to a roughly 20% absolute mortality increase from discharge to 1 year, and questioned what percentage could be attributed to the mechanical support offered.

Dr. Basir said that information was not specifically tracked but that many patients presented with multiorgan failure and, irrespective of that, the majority died from ongoing heart failure.

During the formal presentation, panelist Ron Waksman, MD, MedStar Heart Institute, Washington, questioned whether results were different between academic and community centers, but also pointed to the lack of a comparator in the single-arm study.

“It’s very hard to do any comparison historically; we do need to have a control group,” he said. “If you would have opened it to any treatment at the time of the initiative, which is great, but not just limit it to use of the Impella devices, we would have better understanding if there is really a differentiation between one device versus the other devices.”

Dr. Basir replied, “I think that is a very reasonable comment and, in regard to your question, it is always difficult to differentiate between academic and community centers, but these were large community programs that have all of the technologies available in an academic center.”

NCIS is funded in part by unrestricted grants from Abiomed and Chiesi. Dr. Basir reported consulting for Abbott Vascular, Abiomed, Cardiovascular Systems, Chiesi, Procyrion, and Zoll.

Although vaccination rates against the human papillomavirus remain low for young adults across the United States, the number of self-reported HPV vaccinations among women and men aged between 18 and 21 years has markedly increased since 2010, according to new research findings.

The findings were published online April 27, 2021, as a research letter in JAMA.

In 2006, the Food and Drug Administration approved the HPV vaccine for the prevention of cervical cancer and genital warts in female patients. Three years later, the FDA approved the vaccine for the prevention of anogenital cancer and warts in male patients.

The Advisory Committee on Immunization Practices and the Centers for Disease Control and Prevention recommend two doses of the HPV vaccine for children aged 11-12 years. Adolescents and young adults may need three doses over the course of 6 months if they start their vaccine series on or following their 15th birthday.

For persons who have not previously received the HPV vaccine or who did not receive adequate doses, the HPV vaccine is recommended through age 26. Data on the rates of vaccination among young adults between 18 and 21 years of age in the United States are sparse, and it is not known how well vaccination programs are progressing in the country.

In the recently published JAMA research letter, investigators from the University of Michigan, Ann Arbor, examined data for the period 2010-2018 from the cross-sectional National Health Interview Survey. Respondents included in the analysis were aged 18-21 years. They were asked whether they had received the HPV vaccine before age 18 and at what age they had been vaccinated against the virus.

The researchers also assessed whether the respondents had received any HPV vaccine dose between the ages of 18 and 21 years. The findings were limited to self-reported vaccination status.

In total, 6,606 women and 6,038 men were included in the analysis. Approximately 42% of women and 16% of men said they had received at least one HPV vaccine dose at any age. The proportion of female patients who reported receiving an HPV vaccine dose significantly increased from 32% in 2010 to 55% in 2018 (P =.001). Similarly, among men, the percentage significantly increased from 2% in 2010 to 34% in 2018 (P <.001).

Approximately 4% of the female respondents and 3% of the male respondents reported that they had received an HPV vaccine between the ages of 18 and 21 years; 46% of women and 29% of men who received the vaccine between these ages completed the recommended vaccination series.

Findings from the study highlight the continual need for improving vaccination rates among vulnerable populations. Lead study author Michelle Chen, MD, MHS, a professor in the department of otolaryngology–head and neck surgery at the University of Michigan, explained in an interview that there are multiple barriers to HPV vaccination among young adults. “These barriers to vaccination among young adults primarily include cost, lack of knowledge and awareness, missed opportunities for vaccination, rapidly changing guidelines, and initial gender-based guidelines,” said Dr. Chen.

Clinicians play a large role in improving vaccination rates among young adults, who may lack awareness of the overall importance of inoculation against the potentially debilitating and deadly virus. Dr. Chen noted that clinicians can lead the way by increasing gender-inclusive awareness of HPV-associated diseases and HPV vaccination, by performing routine vaccine eligibility assessments for young adults regardless of sex, by developing robust reminder and recall strategies to improve series completion rates, and by offering patients resources regarding assistance programs to address cost barriers for uninsured patients.

“Young adult men are particularly vulnerable [to HPV], because they start to age out of pediatric health practices,” added Dr. Chen. “Thus, a multilevel gender-inclusive approach is needed to target clinicians, patients, parents, and community-based organizations.”

Gypsyamber D’Souza, PhD, professor of epidemiology at Johns Hopkins University, Baltimore, said in an interview that the initial uptake of HPV vaccination was slow in the United States but that progress has been made in recent years among persons in the targeted age range of 11-12 years. “However, catch-up vaccination has lagged behind, and sadly, we’re still seeing low uptake in those older ages that are still eligible and where we know there still is tremendous benefit,” she said.

Dr. D’Souza is a lead investigator in the MOUTH trial, which is currently enrolling patients. That trial will examine potential biomarkers for oropharyngeal cancer risk among people with known risk factors for HPV who came of age prior to the rollout of the vaccine.

She explained that many parents want their children to be vaccinated for HPV after they hear about the vaccine, but because the health care system in the United States is an “opt-in” system, rather than an “opt-out” one, parents need to actively seek out vaccination. Children then move toward adulthood without having received the recommended vaccine course. “There are individuals who did not get vaccinated at the ages of 11 and 12 and then forget to ask about it later, or the provider asks about it and the patients don’t have enough information,” Dr. D’Souza said.

She noted that one reason why HPV vaccination rates remain low among young adults is that the vaccine is not often kept in stock other than in pediatric clinics. “Because vaccines expire and clinics don’t have a lot of people in that age group getting vaccinated, they may not have it regularly in stock, making this one reason it might be hard for someone to get vaccinated.”

The HPV vaccine is not effective for clearing HPV once a patient acquires the infection, she added. “So young adulthood is a critical time where we have individuals who still can benefit from being vaccinated, but if we wait too long, they’ll age out of those ages where we see the highest efficacy.”

Ultimately, said Dr. D’Souza, clinicians need to catch people at multiple time points and work to remove barriers to vaccination, including letting patients know that HPV vaccination is covered by insurance. “There’s a lot of opportunity to prevent future cancers in young adults by having care providers for that age group talk about the vaccine and remember to offer it.”

Although vaccination rates against the human papillomavirus remain low for young adults across the United States, the number of self-reported HPV vaccinations among women and men aged between 18 and 21 years has markedly increased since 2010, according to new research findings.

The findings were published online April 27, 2021, as a research letter in JAMA.

In 2006, the Food and Drug Administration approved the HPV vaccine for the prevention of cervical cancer and genital warts in female patients. Three years later, the FDA approved the vaccine for the prevention of anogenital cancer and warts in male patients.

The Advisory Committee on Immunization Practices and the Centers for Disease Control and Prevention recommend two doses of the HPV vaccine for children aged 11-12 years. Adolescents and young adults may need three doses over the course of 6 months if they start their vaccine series on or following their 15th birthday.

The inadequacies and challenges of transitioning pediatric rheumatology patients to adult care were highlighted in several research studies shared at the annual scientific meeting of the Childhood Arthritis and Rheumatology Research Alliance.

“Not surprisingly, these studies demonstrate that transition challenges remain pervasive,” Rebecca Sadun, MD, PhD, who was not involved in any of the research, said in an interview. Nevertheless, she pointed out that one of the studies showed that eight of nine sites participating in one of the studies had at least developed a formal transition policy, and three were able to fully integrate that policy into their health care system despite the ongoing pandemic.

In that study, Joyce Chang, MD, of the Children’s Hospital of Philadelphia and colleagues used structured interviews and then quantitative research to explore processes for transition polices across nine rheumatology sites. Aside from the three that had already implemented their policies, three others were preparing implementation. The other three withdrew because of COVID-19. None of the sites had reached sustainment phase. Six of the sites had access to a social work network, and two sites had fewer than four providers.

The authors found that a higher level of change efficacy or change commitment using the Organizational Readiness for Implementing Change framework did not correspond with reaching implementation.

“The first sites to reach implementation had access to [information technology] support and involved nursing, though this was not sufficient or necessary,” the authors wrote. They noted the need for strategies to reduce the burden of data collection to improve the resilience of implementation efforts against health care system stress.
 

Who more often transitions to adult care?

Effective transition policies can help reduce the likelihood of young patients falling through the cracks as they grow from adolescence into young adulthood, especially those at highest risk for losing continuity of care.

“Young adults who are both medically and socially complex are at highest risk,” said Dr. Sadun, an assistant professor of adult and pediatric rheumatology at Duke University, Durham, N.C. “This is especially true for patients with systemic illnesses, patients requiring biologic medications, and patients with custody, transportation, and financial barriers.”

Research led by Emily A. Smitherman, MD, an assistant professor of pediatric rheumatology at Children’s of Alabama in Birmingham, looked more closely at who is and is not transitioning their care. The researchers analyzed retrospective data from the CARRA Registry, including the Long-Term Follow-Up Call Registry, through December 2019. Among 1,311 patients with inactive status, 537 of these patients had juvenile idiopathic arthritis and were aged at least 18 years. Only 186 of those patients, however, had data in the Long-Term Follow-Up Registry. Patients who were Black or had lower income were less likely to have data in the Long-Term Follow-Up Registry.

Just over half the patients in the long-term registry had transferred their care to an adult rheumatologist, and 83% overall were under the care of any physician. Patients who transferred their care were significantly more likely to have private insurance (87% vs. 70%; P = .009) and were more likely to be full-time students (74% vs. 58%; P = .036).

The researchers found no association between patients’ disease status at their last CARRA Registry visit and a successful transition to adult care. However, those who had transferred care to an adult rheumatologist tended to have a higher median level of pain (4 vs. 2 on a scale of 0-10) and more disease activity (3 vs. 1 on 0-10 scale) than did those who had not transferred care (P = .022 and P = .011, respectively). A higher proportion of those who transferred care had also experienced morning stiffness over the past week (49% vs. 30%; P = .015).
 

How young adults prefer to learn transition skills

The third study aimed to better understand the experience and preferences of young adults themselves as they transitioned from pediatric to adult care. Kristine Carandang, PhD, a postdoctoral scholar at the University of California, San Diego, and colleagues first conducted focus groups with 39 adolescents and young adults, ages 16-28 years, who had rheumatic conditions. Using the qualitative data from the focus groups, they designed a survey to capture quantitative data on young patients’ experiences.

“What we’re always trying to work on is, how do we bring that youth voice more clearly into the research literature?” Courtney K. Wells, PhD, MSW, an assistant professor of social work at the University of Wisconsin–River Falls, said in an interview. She noted that both she and Dr. Carandang were patients with rheumatic diseases, so they had lived and grown up with disease themselves and then become researchers.

“We have the information that’s in the literature, but then we also both work with youth in a couple different ways, and what we hear from youth is what we heard in our paper, but it isn’t all represented in the literature,” Dr. Wells said. That disconnect is why they also included two young adults as coauthors in the study.

“As much as we appreciate the model of the six components [of health care transition], we recognize that the youth voice isn’t represented very well,” Dr. Wells said. “The way it’s written is more for doctors and policy makers and targeted for the health care system rather than the young people themselves.”

Their research bore that out. Among 137 survey respondents, aged 18-28 years, the vast majority (89%) were women and most (75%) were White. Half the patients (50%) had a diagnosis of lupus.

“For 9 out of 11 self-management and self-advocacy skills examined, there was a significant difference between how adolescent and young adult patients experienced learning self- management skills versus how they would have preferred to learn the skills,” the researchers concluded. “Overall, adolescent and young adult patients most frequently learned about transition skills from their parents. Most participants would have preferred to learn these skills from their rheumatology team.”

For example, 46.7% of the respondents learned how to communicate their medical history from their parents, but 48.5% would have preferred to learn that from their rheumatology team. Only a quarter (24.8%) had learned that skill from their health care team.

“For most of these skills, they were getting that information from their parents, which is concerning because their parents don’t necessarily have information that is accurate,” Dr. Wells said. “Their parents managed their health care, and they taught them to do it the way they were doing it.”

Just over one-third of respondents said they learned from their parents how to track their symptoms so they could answer the rheumatologists’ questions. Only one in five respondents (20.4%) had learned this skill from their rheumatology team, but 41.2% would have preferred hearing it from their health care team, compared with 22.1% who preferred learning it from their parents.

Nearly half the respondents reported learning from their parents how to advocate for themselves when dissatisfied with their care or symptoms (49.6%) and how to talk to the office staff to make appointments, fill out paperwork, and access health records (47.4%). Just over half (51.5%) would have preferred to learn about office communication from their health care team. Preferences on self-advocacy were split between learning from parents (36.8%) and learning from their health care team (31.6%).

An opportunity for other organizations to support transition

The researchers noted that education did not necessarily need to come only from rheumatologists. Other health care professionals, including nurses and social workers, could help young patients develop skills as well.

“They said they’re also open to talking to other people, but they want their rheumatologist to lead the whole process,” Dr. Wells said. While reimbursement gaps may have presented a barrier in the past, Dr. Wells said that current billing codes have removed that obstacle, allowing physicians to bill for discussing transition skills and care.

“Largely, it’s a time issue,” Dr. Wells said. “Rheumatologists are going to tell patients first about their disease, ask how their medication is working and how their health is. Then, if we have time, we’ll cover the transition pieces, and what it boils down to is that they just don’t have time.”

The respondents indicated an interest in technology that can help their education and transition, such as patient portals, telehealth, and smartphone apps.

While 66.4% of respondents said they would attend an in-person health care appointment to learn skills for transitioning to adult care, 74.5% would attend a telehealth appointment, and 77.2% would complete a structured program within a patient portal.

Dr. Wells said she doesn’t see many of the health care system pressures easing up to allow rheumatologists more time for transition care, but she sees an opportunity for organizations, such as the Arthritis Foundation or Lupus Foundation of America, to step in and help.

“It is a matter of being creative and that, ultimately, is the barrier: Whose job is it to make it happen?” she said. “That’s where some other groups are going to need to be advocates.”

Another notable set of findings from this research was the need for young patients’ access to mental health and sexual/reproductive health services. Just over two-thirds of respondents preferred to discuss these topics with their rheumatology team, but only 59.1% felt comfortable starting the conversation about mental health, and only 47.4% felt comfortable broaching the topic of reproductive/sexual health. Even more patients preferred discussing use of drugs and alcohol with their health care team (71.5%), but more patients also felt comfortable initiating that discussion (72.2%).

“It may be that somebody who’s trained to address those issues, especially the mental health piece, may be more appropriate to have that role, and that’s part of the transition, too, these other larger life issues,” Dr. Wells said. “One of the benefits of going to an adult rheumatologist is that they are the most knowledgeable and prepared to help you with those topics.”

None of the individuals quoted in this story had any disclosures to report.

The respondents indicated an interest in technology that can help their education and transition, such as patient portals, telehealth, and smartphone apps.

While 66.4% of respondents said they would attend an in-person health care appointment to learn skills for transitioning to adult care, 74.5% would attend a telehealth appointment, and 77.2% would complete a structured program within a patient portal.

Dr. Wells said she doesn’t see many of the health care system pressures easing up to allow rheumatologists more time for transition care, but she sees an opportunity for organizations, such as the Arthritis Foundation or Lupus Foundation of America, to step in and help.

“It is a matter of being creative and that, ultimately, is the barrier: Whose job is it to make it happen?” she said. “That’s where some other groups are going to need to be advocates.”

Another notable set of findings from this research was the need for young patients’ access to mental health and sexual/reproductive health services. Just over two-thirds of respondents preferred to discuss these topics with their rheumatology team, but only 59.1% felt comfortable starting the conversation about mental health, and only 47.4% felt comfortable broaching the topic of reproductive/sexual health. Even more patients preferred discussing use of drugs and alcohol with their health care team (71.5%), but more patients also felt comfortable initiating that discussion (72.2%).

“It may be that somebody who’s trained to address those issues, especially the mental health piece, may be more appropriate to have that role, and that’s part of the transition, too, these other larger life issues,” Dr. Wells said. “One of the benefits of going to an adult rheumatologist is that they are the most knowledgeable and prepared to help you with those topics.”

The inadequacies and challenges of transitioning pediatric rheumatology patients to adult care were highlighted in several research studies shared at the annual scientific meeting of the Childhood Arthritis and Rheumatology Research Alliance.

“Not surprisingly, these studies demonstrate that transition challenges remain pervasive,” Rebecca Sadun, MD, PhD, who was not involved in any of the research, said in an interview. Nevertheless, she pointed out that one of the studies showed that eight of nine sites participating in one of the studies had at least developed a formal transition policy, and three were able to fully integrate that policy into their health care system despite the ongoing pandemic.

In that study, Joyce Chang, MD, of the Children’s Hospital of Philadelphia and colleagues used structured interviews and then quantitative research to explore processes for transition polices across nine rheumatology sites. Aside from the three that had already implemented their policies, three others were preparing implementation. The other three withdrew because of COVID-19. None of the sites had reached sustainment phase. Six of the sites had access to a social work network, and two sites had fewer than four providers.

The authors found that a higher level of change efficacy or change commitment using the Organizational Readiness for Implementing Change framework did not correspond with reaching implementation.

“The first sites to reach implementation had access to [information technology] support and involved nursing, though this was not sufficient or necessary,” the authors wrote. They noted the need for strategies to reduce the burden of data collection to improve the resilience of implementation efforts against health care system stress.
 

Who more often transitions to adult care?

Effective transition policies can help reduce the likelihood of young patients falling through the cracks as they grow from adolescence into young adulthood, especially those at highest risk for losing continuity of care.

“Young adults who are both medically and socially complex are at highest risk,” said Dr. Sadun, an assistant professor of adult and pediatric rheumatology at Duke University, Durham, N.C. “This is especially true for patients with systemic illnesses, patients requiring biologic medications, and patients with custody, transportation, and financial barriers.”

Research led by Emily A. Smitherman, MD, an assistant professor of pediatric rheumatology at Children’s of Alabama in Birmingham, looked more closely at who is and is not transitioning their care. The researchers analyzed retrospective data from the CARRA Registry, including the Long-Term Follow-Up Call Registry, through December 2019. Among 1,311 patients with inactive status, 537 of these patients had juvenile idiopathic arthritis and were aged at least 18 years. Only 186 of those patients, however, had data in the Long-Term Follow-Up Registry. Patients who were Black or had lower income were less likely to have data in the Long-Term Follow-Up Registry.

Just over half the patients in the long-term registry had transferred their care to an adult rheumatologist, and 83% overall were under the care of any physician. Patients who transferred their care were significantly more likely to have private insurance (87% vs. 70%; P = .009) and were more likely to be full-time students (74% vs. 58%; P = .036).

The researchers found no association between patients’ disease status at their last CARRA Registry visit and a successful transition to adult care. However, those who had transferred care to an adult rheumatologist tended to have a higher median level of pain (4 vs. 2 on a scale of 0-10) and more disease activity (3 vs. 1 on 0-10 scale) than did those who had not transferred care (P = .022 and P = .011, respectively). A higher proportion of those who transferred care had also experienced morning stiffness over the past week (49% vs. 30%; P = .015).
 

How young adults prefer to learn transition skills

The third study aimed to better understand the experience and preferences of young adults themselves as they transitioned from pediatric to adult care. Kristine Carandang, PhD, a postdoctoral scholar at the University of California, San Diego, and colleagues first conducted focus groups with 39 adolescents and young adults, ages 16-28 years, who had rheumatic conditions. Using the qualitative data from the focus groups, they designed a survey to capture quantitative data on young patients’ experiences.

“What we’re always trying to work on is, how do we bring that youth voice more clearly into the research literature?” Courtney K. Wells, PhD, MSW, an assistant professor of social work at the University of Wisconsin–River Falls, said in an interview. She noted that both she and Dr. Carandang were patients with rheumatic diseases, so they had lived and grown up with disease themselves and then become researchers.

“We have the information that’s in the literature, but then we also both work with youth in a couple different ways, and what we hear from youth is what we heard in our paper, but it isn’t all represented in the literature,” Dr. Wells said. That disconnect is why they also included two young adults as coauthors in the study.

“As much as we appreciate the model of the six components [of health care transition], we recognize that the youth voice isn’t represented very well,” Dr. Wells said. “The way it’s written is more for doctors and policy makers and targeted for the health care system rather than the young people themselves.”

Their research bore that out. Among 137 survey respondents, aged 18-28 years, the vast majority (89%) were women and most (75%) were White. Half the patients (50%) had a diagnosis of lupus.

“For 9 out of 11 self-management and self-advocacy skills examined, there was a significant difference between how adolescent and young adult patients experienced learning self- management skills versus how they would have preferred to learn the skills,” the researchers concluded. “Overall, adolescent and young adult patients most frequently learned about transition skills from their parents. Most participants would have preferred to learn these skills from their rheumatology team.”

For example, 46.7% of the respondents learned how to communicate their medical history from their parents, but 48.5% would have preferred to learn that from their rheumatology team. Only a quarter (24.8%) had learned that skill from their health care team.

“For most of these skills, they were getting that information from their parents, which is concerning because their parents don’t necessarily have information that is accurate,” Dr. Wells said. “Their parents managed their health care, and they taught them to do it the way they were doing it.”

Just over one-third of respondents said they learned from their parents how to track their symptoms so they could answer the rheumatologists’ questions. Only one in five respondents (20.4%) had learned this skill from their rheumatology team, but 41.2% would have preferred hearing it from their health care team, compared with 22.1% who preferred learning it from their parents.

Nearly half the respondents reported learning from their parents how to advocate for themselves when dissatisfied with their care or symptoms (49.6%) and how to talk to the office staff to make appointments, fill out paperwork, and access health records (47.4%). Just over half (51.5%) would have preferred to learn about office communication from their health care team. Preferences on self-advocacy were split between learning from parents (36.8%) and learning from their health care team (31.6%).

An opportunity for other organizations to support transition

The researchers noted that education did not necessarily need to come only from rheumatologists. Other health care professionals, including nurses and social workers, could help young patients develop skills as well.

“They said they’re also open to talking to other people, but they want their rheumatologist to lead the whole process,” Dr. Wells said. While reimbursement gaps may have presented a barrier in the past, Dr. Wells said that current billing codes have removed that obstacle, allowing physicians to bill for discussing transition skills and care.

“Largely, it’s a time issue,” Dr. Wells said. “Rheumatologists are going to tell patients first about their disease, ask how their medication is working and how their health is. Then, if we have time, we’ll cover the transition pieces, and what it boils down to is that they just don’t have time.”

The respondents indicated an interest in technology that can help their education and transition, such as patient portals, telehealth, and smartphone apps.

While 66.4% of respondents said they would attend an in-person health care appointment to learn skills for transitioning to adult care, 74.5% would attend a telehealth appointment, and 77.2% would complete a structured program within a patient portal.

Dr. Wells said she doesn’t see many of the health care system pressures easing up to allow rheumatologists more time for transition care, but she sees an opportunity for organizations, such as the Arthritis Foundation or Lupus Foundation of America, to step in and help.

“It is a matter of being creative and that, ultimately, is the barrier: Whose job is it to make it happen?” she said. “That’s where some other groups are going to need to be advocates.”

Another notable set of findings from this research was the need for young patients’ access to mental health and sexual/reproductive health services. Just over two-thirds of respondents preferred to discuss these topics with their rheumatology team, but only 59.1% felt comfortable starting the conversation about mental health, and only 47.4% felt comfortable broaching the topic of reproductive/sexual health. Even more patients preferred discussing use of drugs and alcohol with their health care team (71.5%), but more patients also felt comfortable initiating that discussion (72.2%).

Some, perhaps many, previously unrecognized cases of atrial fibrillation (AF) will come to light in a screening program aimed at older asymptomatic adults. The key question is whether the challenges of such systematic but age-restricted AF screening in the community, with oral anticoagulation (OAC) offered to those found to have the arrhythmia, is worthwhile in preventing events such as death or stroke.
 

Now there is evidence supporting such a clinical benefit from a large, prospective, randomized trial. A screening program restricted to people 75 or 76 years of age in two Swedish communities, which called on them to use a handheld single-lead ECG system at home intermittently for 2 weeks, was followed by a slight drop in clinical events over about 7 years.

The 4% decline in risk (P = .045) in the STROKESTOP trial’s “intention-to-treat” (ITT) analysis yielded a number needed to treat of 91; that is, that many people had to be targeted by the screening program to prevent one primary-endpoint clinical event.

Those included ischemic stroke, systemic thromboembolism, hospitalization for severe bleeding, and death from any cause, investigators reported April 23 during the virtual European Heart Rhythm Association (EHRA) 2021 Congress.

If that benefit and its significance seem marginal, some secondary findings might be reassuring. Half the population of the target age in the two communities – 13,979 randomly selected people – were invited to join the trial and follow the screening protocol, comprising the ITT cohort. The other half, numbering 13,996, was not invited and served as control subjects.

However, only 51% of the ITT cohort accepted the invitation and participated in the trial; they represented the “as-treated” cohort, observed Emma Svennberg, MD, PhD, Karolinska Institute, Danderyd Hospital, Stockholm, who presented the analysis at the EHRA sessions.

The screening protocol identified untreated AF, whether previously known or unknown, in about 5% of the 7,165 as-treated screening participants; OAC was initiated in about three-fourths of those cases.

The as-treated group, on their own, benefited with a 24% drop in the prospectively defined secondary endpoint of ischemic stroke, compared with the entire control group.

The clinical benefit in the ITT population was “small but significant,” but over the same period in the as-treated cohort, there was a highly significant drop in risk for ischemic stroke, Dr. Svennberg said in an interview.

The trial’s lead message, she said, is that “screening for atrial fibrillation in an elderly population reduces the risk of death and ischemic stroke without increasing the risk of bleeding.”
 

Caveats: As-treated vs. ITT

But there are caveats that complicate interpretation of the trial and, Dr. Svennberg proposed, point to the importance of that interpretation of both the ITT and as-treated analyses.

“We detected significantly more atrial fibrillation in the group that was randomized to screening. A major strength of our study was that we referred all of those individuals for a structured follow-up within the study,” she said. “Although the focus of the follow-up was oral anticoagulant therapy, other risk factors were also assessed and managed, such as hypertension and diabetes.”

It’s possible that increased detection of AF followed by such structured management contributed to the observed benefit, Dr. Svennberg proposed.

However, the exclusion of those in the prespecified ITT population who declined to be screened or otherwise didn’t participate left an as-treated cohort that was healthier than the ITT population or the control group.

Indeed, the nonparticipating invitees were sicker, with significantly more diabetes, vascular disease, hypertension, and heart failure, and higher CHA2DS2VASc stroke risk scores than those who agreed to participate.

“We took a more difficult route in setting up this study, in that we identified all individuals aged 75 to 76 residing in our two regions and excluded no one,” Dr. Svennberg said in an interview. “That means even individuals with end-stage disease, severe dementia, bedridden in nursing homes, et cetera, were also randomized but perhaps not likely or eligible to participate.”

Therefore, some invitees were unable to join the study even as others might have declined “out of low interest” or other personal reasons, she said. “We believe that this mimics how a population-based screening program would be performed if done in our country.”

In the ITT analysis, screening successfully identified previously unknown or untreated cases of AF, which led to expanded OAC use and intensified risk-factor management, “which was key to a successful outcome.”

In the as-treated analysis, Dr. Svennberg said, “I think a combination of the intervention and the population being overall more healthy was driving the secondary endpoint.”
 

Systematic vs. opportunistic screening

Although “opportunistic screening in individuals aged 65 and older” is recommended by current European Society of Cardiology guidelines, systematic screening, such as that used in STROKESTOP, has a much weaker evidence base, observed Renate B. Schnabel, MD, PhD, University Heart & Vascular Center, Hamburg, Germany, as the invited discussant after the STROKESTOP presentation.

STROKESTOP “is one of the first studies, if not the first study,” to show a clinical benefit from screening for AF, Dr. Schnabel said.

Fewer-than-projected primary outcome events were seen during the trial, and event curves for screened and control participants didn’t start to separate until about 4 years into the study, she said. It therefore might take a long time for the screened elderly to realize the clinical benefits of screening.

Studies such as the recent SCREEN-AF and mSTOPS have amply shown that AF screening in the asymptomatic elderly can reveal previously unrecognized AF far more often than would be detected in routine practice, allowing them the opportunity to go on OAC. But the trials weren’t able to show whether the benefits of such management outweigh the risks or costs.

Indeed, on April 20, the U.S. Preventive Services Task Force (USPSTF) released a draft recommendation statement concluding that “the current evidence is insufficient to assess the balance of benefits and harms” associated with AF screening in asymptomatic people at least 50 years of age.

In STROKESTOP, however, benefit for the primary outcome reached significance in the prespecified ITT analysis and “appeared to be driven by the reduction in ischemic stroke incidence,” Dr. Schnabel said.

“The future guidelines have gained strong evidence to judge on systematic atrial fibrillation screening” as it was performed in the trial, she said. “How to implement atrial fibrillation screening, including systematic screening in health care systems across Europe and beyond, remains an open question.”
 

A randomized population

STROKESTOP considered all 75- and 76-year-olds living in Sweden’s Stockholm County (n = 23,888) and the Halland region (n = 4,880) and randomly assigned them to the ITT group or a control group, with stratification by sex, birth year, and geographic region. In both groups, 54.6% were female and the mean CHA2DS2VASc score was 3.5.

People assigned to the ITT cohort were invited to be screened and followed. Those who agreed to participate underwent a baseline ECG assessment to detect or rule out permanent AF. Guideline-based OAC and follow-up was offered to those found with the arrhythmia. Those in sinus rhythm with no history of AF used a handheld single-lead ECG recorder (Zenicor) for 30 seconds twice daily for 14 days.

Structured management, including OAC, was offered to anyone demonstrating sufficient AF, that is, at least one bout without p waves in one 30-second recording or at least two such episodes lasting 10-29 seconds during the 2-week screening period.

In the ITT analysis, the hazard ratio (HR) for the composite clinical primary endpoint was 0.96 (95% confidence interval, 0.920-0.999; P = .045), but in the as-treated analysis, the HR for ischemic stroke was 0.76 (95% CI, 0.68-0.87; P < .001).

“I believe that this will likely be generalizable to most countries’ elderly residents,” Dr. Svennberg said. “I think if we can find a significant difference in our elderly population in Sweden, most countries will be able to do so, or find even more significant results.”

That’s because “baseline detection of AF in Sweden is high,” she said, “so new detection is likely more difficult.” Also, in Sweden, “care can be sought without monetary concern, and prescriptions are provided at low costs to the patients.” Therefore, patients newly identified with AF, whether in studies or not, “would likely be started on therapy.”

It will be important to know whether the screening strategy is cost-effective, Dr. Schnabel said, because “the overall effect, with a hazard ratio of 0.96, is not too big, and costs incurred by systematic screening are comparatively high.”

STROKESTOP “now provides sound information for cost-effectiveness analyses, which to date have largely relied on assumptions.”

STROKESTOP was partially supported by Carl Bennet AB, Boehringer-Ingelheim, Bayer, Bristol-Meyers Squibb, and Pfizer. Dr. Svennberg disclosed receiving fees for lectures or consulting from Bayer, Bristol-Meyers Squibb, Pfizer, Boehringer-Ingelheim, Merck Sharp & Dohme, and Sanofi; and institutional grants from Roche Diagnostics and Carl Bennett Ltd.

In the ITT analysis, screening successfully identified previously unknown or untreated cases of AF, which led to expanded OAC use and intensified risk-factor management, “which was key to a successful outcome.”

In the as-treated analysis, Dr. Svennberg said, “I think a combination of the intervention and the population being overall more healthy was driving the secondary endpoint.”
 

Systematic vs. opportunistic screening

Although “opportunistic screening in individuals aged 65 and older” is recommended by current European Society of Cardiology guidelines, systematic screening, such as that used in STROKESTOP, has a much weaker evidence base, observed Renate B. Schnabel, MD, PhD, University Heart & Vascular Center, Hamburg, Germany, as the invited discussant after the STROKESTOP presentation.

STROKESTOP “is one of the first studies, if not the first study,” to show a clinical benefit from screening for AF, Dr. Schnabel said.

Fewer-than-projected primary outcome events were seen during the trial, and event curves for screened and control participants didn’t start to separate until about 4 years into the study, she said. It therefore might take a long time for the screened elderly to realize the clinical benefits of screening.

Studies such as the recent SCREEN-AF and mSTOPS have amply shown that AF screening in the asymptomatic elderly can reveal previously unrecognized AF far more often than would be detected in routine practice, allowing them the opportunity to go on OAC. But the trials weren’t able to show whether the benefits of such management outweigh the risks or costs.

Indeed, on April 20, the U.S. Preventive Services Task Force (USPSTF) released a draft recommendation statement concluding that “the current evidence is insufficient to assess the balance of benefits and harms” associated with AF screening in asymptomatic people at least 50 years of age.

In STROKESTOP, however, benefit for the primary outcome reached significance in the prespecified ITT analysis and “appeared to be driven by the reduction in ischemic stroke incidence,” Dr. Schnabel said.

“The future guidelines have gained strong evidence to judge on systematic atrial fibrillation screening” as it was performed in the trial, she said. “How to implement atrial fibrillation screening, including systematic screening in health care systems across Europe and beyond, remains an open question.”
 

A randomized population

STROKESTOP considered all 75- and 76-year-olds living in Sweden’s Stockholm County (n = 23,888) and the Halland region (n = 4,880) and randomly assigned them to the ITT group or a control group, with stratification by sex, birth year, and geographic region. In both groups, 54.6% were female and the mean CHA2DS2VASc score was 3.5.

People assigned to the ITT cohort were invited to be screened and followed. Those who agreed to participate underwent a baseline ECG assessment to detect or rule out permanent AF. Guideline-based OAC and follow-up was offered to those found with the arrhythmia. Those in sinus rhythm with no history of AF used a handheld single-lead ECG recorder (Zenicor) for 30 seconds twice daily for 14 days.

Structured management, including OAC, was offered to anyone demonstrating sufficient AF, that is, at least one bout without p waves in one 30-second recording or at least two such episodes lasting 10-29 seconds during the 2-week screening period.

In the ITT analysis, the hazard ratio (HR) for the composite clinical primary endpoint was 0.96 (95% confidence interval, 0.920-0.999; P = .045), but in the as-treated analysis, the HR for ischemic stroke was 0.76 (95% CI, 0.68-0.87; P < .001).

“I believe that this will likely be generalizable to most countries’ elderly residents,” Dr. Svennberg said. “I think if we can find a significant difference in our elderly population in Sweden, most countries will be able to do so, or find even more significant results.”

That’s because “baseline detection of AF in Sweden is high,” she said, “so new detection is likely more difficult.” Also, in Sweden, “care can be sought without monetary concern, and prescriptions are provided at low costs to the patients.” Therefore, patients newly identified with AF, whether in studies or not, “would likely be started on therapy.”

It will be important to know whether the screening strategy is cost-effective, Dr. Schnabel said, because “the overall effect, with a hazard ratio of 0.96, is not too big, and costs incurred by systematic screening are comparatively high.”

STROKESTOP “now provides sound information for cost-effectiveness analyses, which to date have largely relied on assumptions.”

Motor and cognitive aspects of Parkinson’s disease are associated with discrete neural microcircuits within the brain’s basal ganglia, according to a new study using a mouse model of disease. 

Parkinson’s disease is characterized by a range of cognitive and motor symptoms, which appear at different disease stages. While recent research has pointed to specific neuronal subpopulations, or microcircuits, operating in the basal ganglia, researchers lacked a clear understanding of how they might correspond with specific symptom domains. 

In a study published online March 15 in Nature Neuroscience, lead author Varoth Lilascharoen, PhD, of the University of California, San Diego, and colleagues reported that two different neuronal subpopulations within the external globus pallidus, an important nucleus within the basal ganglia, are associated, respectively, with movement and with reversal learning (having to adapt to a reward pattern that is the reverse of a previous pattern). This is the first time, the investigators said, that the contributions of specific microcircuits in the basal ganglia have been linked to different behaviors.

Using electrophysiology, viral tracing, and other approaches, Dr. Lilascharoen and colleagues demonstrated that two microcircuits or populations of parvalbumin-expressing neurons could be manipulated to exacerbate or alleviate the motor or cognitive deficits in the dopamine-depleted mice. 

One of these microcircuits, made up of substantia nigra pars reticulata-projecting GPe-PV neurons, could be manipulated in ways that promoted or inhibited the mice’s movement. The other, which comprises parafascicular thalamus-projecting GPe-PV neurons, could be manipulated to affect reversal learning, the researchers found. Activation or inhibition of either circuit was not seen affecting function in the other. 

The results shed light on the functional organization of the different basal ganglia nuclei at the circuit level, and suggest, the authors argued, that differences in how different neuronal subpopulations adapt to dopamine loss could explain some of the patterns of progression seen in Parkinson’s disease.

The findings “establish the differential contributions from two distinct GPe-PV microcircuits in specific Parkinsonian-like behaviors linked to early and late stages of the disease,” Dr. Lilascharoen and colleagues wrote in their analysis. “[F]urther elucidation of the detailed connectivity of GPe subpopulations to their downstream targets … is needed to fully define the function of each microcircuit and design better therapeutic strategies for the various behavioral impairments of Parkinson’s disease.” 

Commenting on the research, Stefan Lang, MD, PhD, of the University of Calgary in Alberta said, “While Parkinson’s disease is often referred to as a movement disorder, it is well known that nonmotor symptoms, including cognitive and behavioral impairment, are common and debilitating. Impairment of basal ganglia function is known to contribute to these different symptom domains, though the specific circuits have never been elucidated. [Dr.] Lilascharoen et al. tease apart specific basal ganglia circuits associated with motor and behavioral symptoms, thereby providing evidence that distinct microcircuits might contribute to unique behaviours. As technological advances in neuromodulatory therapies continue to improve the spatial and temporal resolution of stimulation, future treatments may allow for specific targeting of behavioral impairment symptoms in Parkinson’s disease.”

SARS-CoV-2 seroprevalence studies of healthcare workers (HCWs) provide valuable insights into the excess risk of infection in this population and indirect evidence supporting the value of personal protective equipment (PPE) use. Seroprevalence estimates are composite measures of exposure risk and transmission mitigation both in the healthcare and community environments. The challenge of interpreting these studies arises from the diversity of HCW vocational roles and work settings in juxtaposition to heterogeneous community exposure risks. In this issue, two studies untangle some of these competing factors.

Investigators from Kashmir, India, assessed the relationship between seropositivity and specific HCW roles and work sites.¹ They found a lower seroprevalence among HCWs at hospitals dedicated to COVID patients, relative to non-COVID hospitals. This seemingly paradoxical finding likely results from a combination of vigilant PPE adherence enforced through a buddy system, restrictive visitation policies, HCW residential dormitories reducing community exposure, and a spillover effect of careful in-hospital exposure avoidance practices on out-of-hospital behavior. A similar spillover effect has been hypothesized for low HCW seroprevalence relative to the surrounding community in California.²

In complement, researchers at a large New York City (NYC) hospital found higher overall HCW seropositivity rates compared with the community, though estimates were strikingly variable after detailed stratification by job function and location.³ The gradient of seroprevalence showed the highest risk among nurses and those in nonclinical, low-wage jobs (eg, patient transport, housekeeping), a finding also seen in another US study prior to adjustment for demographic and community factors.⁴ This finding highlights the association between socioeconomic status, structural community exposure risk factors such as multiple essential workers living within multigenerational households, and the challenges of sickness absenteeism. High seroprevalence among nurses and emergency department HCWs (who expeditiously evaluate many undifferentiated patients) may reflect both greater aggregate duration of exposure to infected patients and increased frequency of PPE donning and doffing, resulting in fatigue and diminished vigilance.⁵

A NYC-based study similarly showed high HCW seroprevalence, although no consistent associations with job function (albeit measured with less granularity) or community-based exposures were identified.⁶ Several studies comparing HCW to local community seropositivity rates have reached disparate conclusions.^2,7 These contrasting data may result from variability in vigilance of PPE use, mask use in work rooms or during meals/breaktimes, sick leave policies driven by staffing demands, and neighborhood factors. In addition, selection biases and timing of blood sampling relative to viral transmission peaks (with differing degrees of temporal antibody waning) may contribute to the apparent discordance. In particular, comparative community-based samples vary greatly in their inclusion of asymptomatic patients, which can substantially affect such estimates by changing the denominator population.

We draw three conclusions: (1) Evidence for HCW exposure often tracks with community infection rates, suggesting that nonworkplace exposures are a dominant source of HCW seropositivity; (2) vigilant PPE use and assertively implemented protective measures unrelated to patient encounters can dramatically reduce infection risk, even among those with frequent exposures; and (3) HCW infection risk during future peaks can be effectively restrained with adequate resources and support, even in the presence of variants for which no effective vaccination or preventive pharmacotherapy exists. Given the divergent seroprevalence rates found in these studies after detailed stratification by job function and location, it is important for future studies to evaluate their relationship with infectious risk. Accurately quantifying the excess risks borne by HCWs may remain an elusive objective, but experiential knowledge offers numerous strategies worthy of proactive implementation to preserve HCW safety and well-being.

Bronchiolitis, the most common cause of hospital admission for infants, is responsible for more than $500 million in direct medical costs in the United States yearly. Recent efforts have focused on what can be safely avoided when caring for patients with bronchiolitis (eg, continuous pulse oximetry, bronchodilator administration). While there remains substantial room for improvement in avoiding such low-value (or no-value) practices, the incremental improvements from these de-escalations will reach an asymptote over time. Further improvements in care and value must occur by doing things differently—not just simply doing less.

In this month’s Journal of Hospital Medicine, Ohlsen et al¹ describe an intervention to decrease length of stay (LOS) for patients with bronchiolitis They employed an interrupted time series analysis to evaluate implementation of an observation unit and home oxygen therapy (OU-HOT) model of care and found that LOS dramatically decreased immediately following implementation. This reduction was maintained over 9 years. Use of home oxygen decreased over the study period, while LOS remained low, suggesting that the most important intervention was a structural one—the admission of patients to a unit dedicated to efficient discharge.

Observation units, staffed 24/7 with attending physicians, are well adapted to care for patients with illnesses like bronchiolitis, where hospitalization, though often needed, may be brief.² These units are designed more like an emergency department than an inpatient unit, with protocolized care and the expectation of rapid turnover.

Multiple studies have shown that physician-related delays are a primary driver of delayed discharge from inpatient units. Such delays include delayed or variable clinical decision-making, inadequate communication of discharge criteria, and waiting to staff patients with an attending physician.^3-5 Addressing these issues could allow inpatient units to function more like observation units for specific diagnoses. Standardization of care around specific diagnoses can make decision-making and discharge more efficient. In 2014, White et al⁴ showed that standardizing discharge criteria for specific diagnoses (including bronchiolitis) and embedding these criteria in admission order sets resulted in a significant decrease in LOS without affecting readmission rates or patient satisfaction.

To address the issues of attending availability, we may need to rethink rounding. The daily structure of inpatient rounding has not meaningfully changed since the 1950s. While there has been a push for increased morning discharges, this approach misses many patients whose illness course is evolving and who may be ready for discharge in the afternoon or evening.⁶ The current structure of morning rounds on medical teams is based on the need for resident education, supervision, and time available for attendings to complete administrative tasks and teaching in the afternoons. Structural change in patient care requires academic institutions to rethink what “being on service” actually means. Since LOS in these cases is brief, multiple days of clinical continuity may not be as beneficial as with other diagnoses. Further, there is no reason that daytime rounding teams are the only teams that can discharge patients. Telemedicine could also offer an opportunity for attending physicians to remotely determine whether a patient is discharge appropriate. Standardization of discharge criteria at admission could allow for trainees to discharge patients when they meet those criteria.

Perhaps we should begin to adapt our work structure to our patients’ needs, rather than the other way around. In pediatrics, we have already made traditional rounding more patient-focused through the practice of family-centered rounding. We should identify, as the authors have, ways to do things differently to make further improvements in care.

Ultimately, the success of this OU-HOT protocol demonstrates the power of structural interventions aimed at changing how we do things rather than just doing more (or less) of the same.

Sintilimab improved both overall survival (OS) and progression-free survival (PFS), according to Yuankai Shi, MD, of the Chinese Academy of Medical Sciences & Peking Union Medical College in Beijing.

Dr. Shi presented these findings, from the ORIENT-3 study, at the American Association for Cancer Research Annual Meeting 2021: Week 1 (Abstract CT041).

ORIENT-3 enrolled and randomized 290 patients with stage IIIB/IIIC or IV sqNSCLC and disease progression during or after first-line platimum-based chemotherapy. They were randomized 1:1 to receive sintilimab at 200 mg or docetaxel at 75 mg/m²intravenously every 3 weeks until disease progression or intolerable toxicity.

The median age was 60 years in the sintilimab arm and 61 years in the docetaxel arm. A majority of patients were men (94% in the sintilimab arm and 90% in the docetaxel arm), most were current or former smokers (90% and 80%, respectively), and more than three-quarters had an ECOG performance status of 1 (76% and 77%, respectively). More than half of patients had a PD-L1 tumor proportion score (TPS) of 1% or greater (57% and 47%, respectively), and 81% of patients in both arms had stage IV disease.

Results: Survival and safety

Patients in the sintilimab arm received a median of 8.0 cycles of therapy (range, 1-45), and those in the docetaxel arm received a median of 2.0 cycles of therapy (range, 1-15).

At a median follow-up of 23.56 months, the median OS was significantly longer in the sintilimab arm than in the docetaxel arm – 11.79 months and 8.25 months, respectively (hazard ratio, 0.74; P = .02489). OS benefits were generally consistent across subgroups.

The secondary endpoints of PFS and objective response rate also favored sintilimab, Dr. Shi reported.

The median PFS was 4.30 months in the sintilimab arm and 2.79 months in the docetaxel arm (HR, 0.52; P < .00001). Confirmed objective response rates were 25.5% and 2.2%, respectively; the median duration of response was 12.45 months and 4.14 months, respectively; and disease control rates were 65.5% and 37.8%, respectively.

“Sintilimab had a favorable safety profile over docetaxel, with a lower frequency of grade 3 or higher treatment-related adverse events, with no new safety signals observed,” Dr. Shi said.

Treatment-related adverse events (TRAEs) occurred in 84.7% of patients receiving sintilimab and 83.1% of those receiving docetaxel. Hypothyroidism was the most common TRAE in the sintilimab arm (18.1%), and alopecia was the most common TRAE in the docetaxel arm (34.6%).

Grade 3 or higher TRAEs were less frequent in the sintilimab arm than in the docetaxel arm (18.1% vs. 36.2%). Rates of discontinuation because of TRAEs were 12.5% and 5.4% in the sintilimab and docetaxel arms, respectively. TRAEs leading to death occurred in five patients in the sintilimab arm and one in the docetaxel arm.

Use in the real world

Noting sintilimab’s significant OS and PFS benefits as well as superior response rate and duration of response, Dr. Shi concluded, “Sintilimab might provide an alternative second-line treatment option for advanced and metastatic sqNSCLC.”

AACR moderator Marina Garassino, MD, of the University of Chicago, commented on the potential utility of sintilimab and tislelizumab, another checkpoint inhibitor that was evaluated in NSCLC in the RATIONALE 303 trial (AACR 2021, Abstract CT039). Dr. Garassino observed that both drugs have demonstrated superiority to docetaxel as second-line therapy in NSCLC.

Although there have been no head-to-head trials, sintilimab and tislelizumab appear to be very similar to the already approved immune checkpoint inhibitors, which are currently being used as first-line treatment.

“That similarity would make them inappropriate for second-line treatment, except in countries where immune checkpoint inhibitors are not yet approved for first-line therapy,” Dr. Garassino noted.

When asked to comment on the higher treatment-related death rate observed with sintilimab, Dr. Garassino said, “We need to remember that these drugs were developed in China with a population that may have a side effect profile differing from that of a Western population. Also, we are very familiar with this class of drugs and know how to treat their side effects. Similar drugs but different populations and different trials, so it’s very hard to judge.”

Dr. Garassino speculated that with the “super expensive” price tags on the new checkpoint inhibitors, having additional agents that could provide choice and drive prices down would be welcome.

Plasma levels of neurofilament light (NfL) are a better predictor of cognitive decline and changes in neuroimaging in comparison with total tau (T-tau), new research suggests. In certain contexts, T-tau improves cross-sectional analyses of these outcomes, but adding T-tau measurements to NfL measurements does not improve the predictive power of NfL, results of a longitudinal analysis show.

“The major distinction, for cognition at least, was that NfL cross-sectionally was associated with most cognitive outcomes, and longitudinally, higher NfL at baseline was associated with cognitive decline in every domain,” said study investigator Jordan Marks, an MD/PhD student at the Mayo Medical School, Rochester, Minn.

The findings were presented at the American Academy of Neurology’s 2021 annual meeting.
 

New tool for dementia diagnosis?

In recent years, researchers have studied NfL and T-tau as potential blood-based biomarkers of neurodegeneration. In cross-sectional and longitudinal studies, NfL and T-tau have been associated with worse cognition and with neuroimaging measures of cortical thickness, cortical atrophy, white-matter hyperintensity, and white-matter integrity. However, no previous research has directly compared the prognostic ability of these two biomarkers.

The study included 995 participants without dementia in the Mayo Clinic Study on Aging. All participants underwent measurement of NfL and T-tau and assessment of cognitive status, as well as neuroimaging. The investigators measured NfL and T-tau on the Simoa HD-1 platform. They reexamined patients approximately every 15 months. The median follow-up time was 6.2 years.

To examine associations between baseline plasma NfL or T-tau and cognitive or neuroimaging outcomes, the researchers conducted data analyses using linear mixed effects models and adjusted the data for age, sex, and education. They replicated these analyses using data from the Alzheimer’s Disease Neuroimaging Initiative (ADNI). For these analyses, they selected 387 participants without dementia who had been followed for a median of 3.0 years.

In all analyses, baseline plasma NfL was more strongly associated with cognitive and neuroimaging outcomes than T-tau. “Baseline plasma NfL was associated with cognitive decline in all domains measured, while T-tau was not associated with cognitive decline,” said Mr. Marks.

Plasma NfL was more strongly associated with decreases in cortical thickness over time than T-tau was. NfL was also more strongly associated with declining hippocampal volume and white-matter changes.

However, in cross-sectional analysis, the combination of elevated NfL levels and elevated T-tau levels at baseline was more strongly associated with decreased global cognition and memory, compared with elevated NfL levels alone. The combination also was more strongly associated with neuroimaging measures, such as temporal cortex thickness and increased number of infarcts. However, in longitudinal analyses, T-tau did not add to the predictive value of NfL.

The analyses using ADNI data yielded similar results. Overall, the results suggest that NfL is a better prognostic marker of neurodegeneration in general, said Mr. Marks.

These findings, he said, may have implications for screening and diagnosis. “I’m definitely hopeful that NfL will be useful in a clinical setting to screen for those at risk of dementia and will be helpful, along with other modalities, like cognitive testing, for dementia diagnosis,” said Mr. Marks.

Future research should examine how changes in these biomarkers are associated with cognitive and neuroimaging outcomes over time.

“We used plasma levels at one point in time in this study, but we need a better sense of how to interpret, for example, what a rise in plasma NfL over a certain time period means for someone’s risk of developing neurodegenerative disease,” Mr. Marks added.
 

An ‘exciting’ prospect

Commenting on the study, Glen R. Finney, MD, director of the Memory and Cognition Program for Geisinger Health in Wilkes-Barre, Pa., said the findings add to neurologists’ ability to screen for brain diseases. “Evidence of neurodegeneration is part of the modern diagnosis of several disorders. While brain imaging can also provide that and may be needed for other reasons, this could provide an easy, potentially inexpensive way to screen for damage to the brain, giving us an added tool,” said Dr. Finney.

The prospect of using blood plasma markers to explore disease of the brain is exciting, Dr. Finney added. “I would like to see ongoing refinement of this approach and would like to see if there’s other markers in blood that could be used to find what specifically may be causing the damage,” he said.

The study was funded by the National Institutes of Health, the National Institute on Aging, and the GHR Foundation. Mr. Marks and Dr. Finney have disclosed no relevant financial relationships.
