Implications of Race Adjustment in Lung-Function Equations.

BACKGROUND: Adjustment for race is discouraged in lung-function testing, but the implications of adopting race-neutral equations have not been comprehensively quantified. METHODS: We obtained longitudinal data from 369,077 participants in the National Health and Nutrition Examination Survey, U.K. Biobank, the Multi-Ethnic Study of Atherosclerosis, and the Organ Procurement and Transplantation Network. Using these data, we compared the race-based 2012 Global Lung Function Initiative (GLI-2012) equations with race-neutral equations introduced in 2022 (GLI-Global). Evaluated outcomes included national projections of clinical, occupational, and financial reclassifications; individual lung-allocation scores for transplantation priority; and concordance statistics (C statistics) for clinical prediction tasks. RESULTS: Among the 249 million persons in the United States between 6 and 79 years of age who are able to produce high-quality spirometric results, the use of GLI-Global equations may reclassify ventilatory impairment for 12.5 million persons, medical impairment ratings for 8.16 million, occupational eligibility for 2.28 million, grading of chronic obstructive pulmonary disease for 2.05 million, and military disability compensation for 413,000. These potential changes differed according to race; for example, classifications of nonobstructive ventilatory impairment may change dramatically, increasing 141% (95% confidence interval [CI], 113 to 169) among Black persons and decreasing 69% (95% CI, 63 to 74) among White persons. Annual disability payments may increase by more than $1 billion among Black veterans and decrease by $0.5 billion among White veterans. GLI-2012 and GLI-Global equations had similar discriminative accuracy with regard to respiratory symptoms, health care utilization, new-onset disease, death from any cause, death related to respiratory disease, and death among persons on a transplant waiting list, with differences in C statistics ranging from -0.008 to 0.011. CONCLUSIONS: The use of race-based and race-neutral equations generated similarly accurate predictions of respiratory outcomes but assigned different disease classifications, occupational eligibility, and disability compensation for millions of persons, with effects diverging according to race.

The Planetary Benefit of Suspending USMLE Step 2 CS: Estimating Carbon Emissions Associated with US Medical Students' Travel to Testing Centers.

Background: The discontinuation of the Step 2 Clinical Skills Exam (CS) by the United States Medical Licensing Examination (USMLE) eliminated the need for personal travel to testing centers. The carbon emissions associated with CS have not been previously quantified. Objective: To estimate the annual carbon emissions generated by travel to CS Testing Centers (CSTCs) and to explore differences across geographic regions. Methods: We conducted a cross-sectional, observational study by geocoding medical schools and CSTCs to calculate the distance between them. We obtained data from the 2017 matriculant databases of the Association of American Medical Colleges (AAMC) and the American Association of Colleges of Osteopathic Medicine (AACOM). The independent variable was the location as defined by USMLE geographic regions. The dependent variables were distance traveled to CSTCs and estimated carbon emissions in metric tons CO2 (mtCO2) calculated using three models. In model 1 all students used single occupancy vehicles; in model 2, all carpooled; and in model 3, half traveled by train and half by single occupancy vehicle. Results: Our analysis included 197 medical schools. The mean out-of-town travel distance was 280.67 miles (IQR: 97.49-383.42). The mtCO2 associated with travel was 2,807.46 for model 1; 3,135.55 for model 2; and 635.34 for model 3. The Western region traveled the farthest, while the Northeast traveled significantly less than other regions. Conclusion: The annual estimated carbon emissions from travel to CSTCs was approximately 3,000 mtCO2. Northeastern students traveled the shortest distances; the average US medical student expended 0.13 mtCO2. Medical leaders must consider the environmental impact of medical curricula and pursue accordant reforms.

Medical Schools as Racialized Organizations: How Race-Neutral Structures Sustain Racial Inequality in Medical Education-a Narrative Review.

In 2021, The American Association of Medical Colleges released a framework addressing structural racism in academic medicine, following the significant, nationwide Movement for Black Lives. The first step of this framework is to "begin self-reflection and educating ourselves." Indeed, ample evidence shows that medical schools have a long history of racially exclusionary practices. Drawing on racialized organizations theory from the field of sociology, we compile and examine scholarship on the role of race and racism in medical training, focusing on disparities in educational and career outcomes, experiences along racial lines in medical training, and long-term implications. From the entrance into medical school through the residency application process, organizational factors such as reliance on standardized tests to predict future success, a hostile learning climate, and racially biased performance metrics negatively impact the careers of trainees of color, particularly those underrepresented in medicine (URiM). Indeed, in addition to structural biases associated with otherwise "objective" metrics, there are racial disparities across subjective outcomes such as the language used in medical trainees' performance evaluations, even when adjusting for grades and board exam scores. These disadvantages contribute to URIM trainees' lower odds of matching, steering into less competitive and lucrative specialties, and burnout and attrition from academic careers. Additionally, hostile racial climates and less diverse medical schools negatively influence White trainees' interest in practicing in underserved communities, disproportionally racial and ethnic minorities. Trainees' mental health suffers along the way, as do medical schools' recruitment, retention, diversity, and inclusion efforts. Evidence shows that seemingly race-neutral processes and structures within medical education, in conjunction with individuals' biases and interpersonal discrimination, may reproduce and sustain racial inequality among medical trainees. Medical schools whose goals include training a more diverse physician workforce towards addressing racial health disparities require a new playbook.

"They Wanted to Talk to a 'Real Doctor'": Predictors, Perpetrators, and Experiences of Racial and Ethnic Discrimination Among Healthcare Workers.

BACKGROUND: Racial and ethnic diversity of healthcare workers have benefits on team functioning and patient care. However, a significant barrier to retaining diverse providers is discrimination. OBJECTIVE: To assess the predictors, perpetrators, and narratives of racial discrimination among healthcare workers. DESIGN: Survey study. PARTICIPANTS: Healthcare workers employed at academic hospitals. MAIN MEASURES: We assessed prevalence and perpetrators of racial and ethnic discrimination using the General Ethnic Discrimination Scale. We included an open-ended question asking respondents to recount experiences of discrimination and analyzed responses using grounded theory. KEY RESULTS: Of the 997 participants, 12.2% were females from backgrounds underrepresented in medicine (URM), 4.0% URM males, 10.1% Asian females, 4.7% Asian males, 49.1% non-Hispanic White females, and 19.8% non-Hispanic White males. Among healthcare workers of color, 85.2% reported discrimination. Over half of URM females (51.4%), URM males (52.6%), and Asian females (62.5%) reported discrimination by patients. About 20-25% of URM females, URM males, and Asian females reported discrimination by teachers, supervisors, co-workers, and institutions. In adjusted binary logistic models, URM females had 10.14 odds (95% confidence interval [95%CI]: 5.13, 20.02, p<.001), URM males 6.23 odds (95%CI: 2.59, 14.98, p<.001), Asian females 7.90 odds (95%CI: 4.07, 15.33, p<.001), and Asian males 2.96 odds (95% CI: 1.47, 5.97, p=.002) of reporting discrimination compared with non-Hispanic White males. Needing more support was associated with 2.51 odds (95%CI: 1.54, 4.08, p<.001) of reporting discrimination. Our qualitative findings identified that the murder of George Floyd intensified URM healthcare workers' experiences of discrimination through increased fear of violence and requests for unpaid diversity work. Asian healthcare workers reported that pandemic-related anti-Asian violence shaped their experiences of discrimination through increased fear of violence and care refusal from patients. CONCLUSIONS: Our findings provide insights into experienced discrimination among healthcare workers and opportunities for hospitals to create programs that improve inclusivity.

The Association of Microaggressions with Depressive Symptoms and Institutional Satisfaction Among a National Cohort of Medical Students.

BACKGROUND: Despite substantial research on medical student mistreatment, there is scant quantitative data on microaggressions in US medical education. OBJECTIVE: To assess US medical students' experiences of microaggressions and how these experiences influenced students' mental health and medical school satisfaction. DESIGN AND PARTICIPANTS: We conducted a cross-sectional, online survey of US medical students' experiences of microaggressions. MAIN MEASURES: The primary outcome was a positive depression screen on the 2-item Patient Health Questionnaire (PHQ-2). Medical school satisfaction was a secondary outcome. We used logistic regression to model the association between respondents' reported microaggression frequency and the likelihood of a positive PHQ-2 screen. For secondary outcomes, we used the chi-squared statistic to test associations between microaggression exposure and medical school satisfaction. KEY RESULTS: Out of 759 respondents, 61% experienced at least one microaggression weekly. Gender (64.4%), race/ethnicity (60.5%), and age (40.9%) were the most commonly cited reasons for experiencing microaggressions. Increased microaggression frequency was associated with a positive depression screen in a dose-response relationship, with second, third, and fourth (highest) quartiles of microaggression frequency having odds ratios of 2.71 (95% CI: 1-7.9), 3.87 (95% CI: 1.48-11.05), and 9.38 (95% CI: 3.71-26.69), relative to the first quartile. Medical students who experienced at least one microaggression weekly were more likely to consider medical school transfer (14.5% vs 4.7%, p<0.001) and withdrawal (18.2% vs 5.7%, p<0.001) and more likely to believe microaggressions were a normal part of medical school culture (62.3% vs 32.1%) compared to students who experienced microaggressions less frequently. CONCLUSIONS: To our knowledge, this is the largest study on the experiences and influences of microaggressions among a national sample of US medical students. Our major findings were that microaggressions are frequent occurrences and that the experience of microaggressions was associated with a positive depression screening and decreased medical school satisfaction.

The Government's Involvement in Prenatal Drug Testing May Be Toxic.

In 25 U.S. states, healthcare professionals are mandated to report pregnant people for substance use to child protection service (CPS) agencies. This practice is not evidence-based, and we believe it harms the patient-provider relationship, opposes reproductive autonomy, and contributes to racial disparities in CPS referrals and their outcomes. Black patients are more often screened and reported than white patients for prenatal substance use; besides the impact on their obstetric care, this may be a barrier to seeking treatment for substance use disorders. Furthermore, strict, punitive state-level policies are associated with greater odds of neonatal abstinence syndrome. The treatment of substance use disorders in pregnancy under the Child Abuse Prevention and Treatment Act opposes robust evidence understanding substance use disorders as chronic illnesses. Among non-pregnant people seeking healthcare, substance use is not a "reportable offense." This double marginalization of pregnant patients limits their autonomy and unduly exposes them to the criminal-legal system. Given disparities in prenatal drug screening, Black pregnant patients are at greater risk of such double-jeopardy. Public health and medical organizations have released policy statements against states' punitive laws, but little has changed. Healthcare providers and institutions should prioritize evidence-based care to benefit the health and wellbeing of birthing person and their infant and combat "legal" interference at the clinic and public-health scale.

Medical Schools as Racialized Organizations: A Primer.

The year 2020 saw the largest social movement in response to the police killings of Black people and anti-Black racism in U.S. history. As a result, medical schools and professional societies such as the American Medical Association and the Association of American Medical Colleges are reckoning with their role in perpetuating racial inequality and the impact of structural racism on medical training. Whether these efforts will translate into meaningful change has yet to be determined. Success depends on a deep understanding of the fundamental role racism plays in how medical schools function and an acknowledgment that current organizational structures and processes often serve to entrench, not dismantle, racial inequities. Drawing on racialized organizations theory from the field of sociology, this article gives an overview of scholarship on race and racism in medical training to demonstrate how seemingly race-neutral processes and structures within medical education, in conjunction with individuals' biases and interpersonal discrimination, serve to reproduce and sustain racial inequality. From entrance into medical school through the residency application process, organizational factors such as reliance on standardized tests to predict future success, a hostile learning climate, and racially biased performance metrics ultimately stunt the careers of trainees of color, particularly those from backgrounds underrepresented in medicine (URM). These compounding disadvantages contribute to URM trainees' lower matching odds, steering into less competitive and lucrative specialties, and burnout and attrition from academic careers. In their commitment against structural racism in medical training and academic medicine, medical schools and larger organizations like the Association of American Medical Colleges should prioritize interventions targeted at these structural barriers to achieve equity.

Cardiac surgeons' perspectives and practices regarding people who use drugs: A scoping review.

BACKGROUND AND AIM OF STUDY: The rising rates of drug use and associated cardiovascular complications, particularly infective endocarditis, have led to poorer health outcomes for people who use drugs (PWUD). The objectives of this scoping review were to identify (1) attitudes of cardiac surgeons toward PWUD and (2) challenges faced in the surgical treatment of drug use-related disease. METHODS: A comprehensive literature search of three databases was performed with this assistance of a medical librarian. Articles were screened and analyzed for common themes by two independent authors. After literature review, a scoping review was conducted according to preferred reporting items for systematic reviews and meta-analyses and Joanna Briggs Institute guidelines, summarizing existing evidence. RESULTS: Analysis of 35 qualified articles revealed eight themes regarding the perspectives and practices of cardiac surgeons toward PWUD: (1) need for multidisciplinary care teams (45.7%); (2) insufficient resources for treatment of underlying substanceuse disorders (40.0%); (3) stigma toward PWUD (37.1%); (4) willingness of surgeons to operate (31.4%); (5) incomplete guidelines for surgical management of drug-use related infective endocarditis (17.1%); (6) recognizing the importance of psychosocial factors (14.3%); (7) use of drug abstinence contracts (14.3%); and (8) use of stigmatizing language to describe PWUD and/or sterile injection (40.0%). CONCLUSIONS: Provision of equitable care for PWUD requires effort from multiple disciplines including cardiothoracic surgeons, infectious disease specialists, addiction medicine specialists, and social workers. Additionally, further research is needed to gather sufficient data for evidence-based guidelines in the treatment of cardiac complications in PWUD.

Cardiac surgeons' practices and attitudes toward addiction care for patients with substance use disorders.

INTRODUCTION: Rates of injection-drug use associated infective endocarditis (IDU-IE) are rising, and most patients with IDU-IE do not receive addiction care during hospitalization. We sought to characterize cardiac surgeons' practices and attitudes toward patients with IDU-IE due to their integral role treating them. METHODS: This is a survey of 201 cardiac surgeons in the U.S who were asked about the addiction care they engage for patients with IDU-IE along with questions pertaining to stigma against people who use drugs (PWUD). Descriptive statistics and multivariable logistic regression were used to identify patterns in surgeons' practices and determine associations between attitudes toward substance use disorder (SUD) and beliefs about medications for opioid use disorder (MOUD). RESULTS: A minority of surgeons have access to specialty addiction services (35%) in their hospital, but when available 93% consult them for patients with IDU-IE. A quarter of surgeons reported thinking that SUD is a choice and do not believe MOUD have a role in reducing IDU-IE recurrence. Conversely, 69% of surgeons agreed with the disease model of addiction and were four times more likely to believe that MOUD has a role in reducing IDU-IE recurrence (aOR 4.09, 95% CI 1.8-9.27, p = 0.001). CONCLUSION: Access to addiction specialists is limited in most hospital settings, but when available, most surgeons report consulting them and supporting MOUD. However, a significant proportion of surgeons hold non-evidence-based attitudes toward SUD and PWUD. This suggests that lack of education and stigma may affect the care of patients with IDU-IE, highlighting the need for education about, and destigmatization of addiction within health systems.

Urban residential tree canopy and perceived stress among pregnant women.

OBJECTIVE: To examine the association of urban residential tree canopy cover with perceived stress in a cohort of pregnant women in Philadelphia, PA, and explore whether this association differed among participants with a history of anxiety and depression. STUDY DESIGN: We performed a secondary analysis of 1294 participants of the Motherhood & Microbiome (M&M) pregnancy cohort who lived in Philadelphia, with first visit perceived stress (Cohen's Perceived Stress Scale, PSS-14), and key covariate data. Tree canopy cover was calculated as percent cover within 100 and 500 m radii buffers around participants' homes. We performed multilevel mixed effects linear regression models, with perceived stress as the dependent variable. The main independent variable was tree canopy coverage. Individual-level covariates included season of last menstrual period, history of depression or anxiety, race/ethnicity, insurance, parity, and age. Census tract neighborhood deprivation index was used to account for area-level socioeconomic confounding variables. We also examined whether a history of anxiety or depression, modified the association between tree canopy coverage and perceived stress. RESULTS: Most participants were non-Hispanic Black (70.6%, n = 913), on Medicaid or uninsured (60.4%, n = 781), and 15.8% (n = 204) of participants had a prior history of depression or anxiety. We did not detect associations between tree canopy coverage and perceived stress overall. However, we detected effect modification; among participants with a history of depression or anxiety, each standard deviation increase in tree canopy cover was associated with lower PSS-14 in 100 m buffers (ß -1.0, 95% CI -1.8, -0.2), but not among participants with no histories of depression or anxiety (ß 0.2, 95% CI -0.3, 0.7) (interaction P = 0.007). Results were similar in directionality but not statistically significant within 500 m buffers. CONCLUSION: Residential tree canopy coverage was associated with reduced perceived stress among urban-dwelling pregnant women with history of anxiety or depression. Future studies of the effects of greenness and other stress-reducing efforts should consider underlying mental health conditions as effect modifiers.

Who is Biking for? Urban Bikeshare Networks' Responses to the COVID-19 Pandemic, Disparities in Bikeshare Access, and a Way Forward.

Black, Latinx, and Indigenous people have contracted the SARS-CoV-2 virus and died of COVID-19 at higher rates than White people. Individuals rated public transit, taxis, and ride-hailing as the modes of transportation putting them at greatest risk of COVID-19 infection. Cycling may thus be an attractive alternative for commuting. Amid the increase in bikeshare usage during the early months of the pandemic, bikeshare companies made changes to membership requirements to increase accessibility, targeting especially essential workers. Essential workers in the United States are disproportionately Black and Latinx, underpaid, and reliant on public transit to commute to work. We document changes made by bikeshare companies, including benefits to various groups of essential workers, and we discuss such changes in the context of longstanding racial disparities in bikeshare access. While well intended, the arbitrary delineation in eligibility for such benefits by class of essential workers unwittingly curtailed access for many who may have benefited most. Given that equity in bikeshare is an important tool to improve access to safe transportation, critical changes in the distribution, accessibility, and usability of bikeshare networks is essential. Bikeshare companies, city planners, and policy makers should collaborate with community-based bike advocates to implement changes, as vocalized by those most in need of alternative forms of transportation.

Isolated Tricuspid Valvectomy: A Series of cases with Intravenous Drug Abuse Associated Tricuspid Valve Endocarditis.

INTRODUCTION: Surgical management for tricuspid valve (TV) endocarditis is usually TV repair or replacement. When repair is not feasible, and concerns for patient recidivism preclude TV replacement, tricuspid valvectomy without replacement is an option to alleviate symptoms and allow time for addiction management. METHODS: We reviewed our institution's experience with isolated tricuspid valvectomy for cases of intravenous drug use (IVDU)-associated endocarditis (n = 7) from 2009 to 2017. RESULTS: The decision for tricuspid valvectomy was based on each patient's comorbid condition and realization of active IVDU. This intervention resulted in 100% perioperative and mid-term survival with a mean follow-up of 25.4 months. One patient required a valve replacement in the long term only after appropriate substance abuse management was completed. CONCLUSION: Cardiac surgeons increasingly encounter patients with active endocarditis who suffer from IVDU addiction. Drug addiction increases the risk for recurrent endocarditis and requires an effective management plan. Multidisciplinary endocarditis care teams may play a pivotal role in improving outcomes by better addressing addiction treatment.

Understanding and Addressing Widening Racial Inequalities in Drug Overdose.

The fourth wave of the United States overdose crisis-driven by the polysubstance use of fentanyl with stimulants and other synthetic substances-has driven sharply escalating racial/ethnic inequalities in drug overdose death rates. Here the authors present a detailed portrait of the latest overdose trends and synthesize the literature to describe where, how, and why these inequalities are worsening. By 2022 overdose deaths among Native and Black Americans rose to 1.8 and 1.4 times the rate seen among White Americans, respectively. This reflects that Black and Native Americans have been disproportionately affected by fentanyl and the combination of fentanyl and stimulants at the national level and in virtually every state. The highest overdose deaths rates are currently seen among Black Americans 55-64 years of age as well as younger cohorts of Native Americans 25-44 years of age. In 2022-the latest year of data available-deaths among White Americans decreased relative to 2021, whereas rates among all other groups assessed continued to rise. Moving forward, Fundamental Cause Theory shows us a relevant universal truth of implementation science: in socially unequal societies, new technologies typically end up favoring more privileged groups first, thereby widening inequalities unless underlying social inequalities are addressed. Therefore, interventions designed to reduce addiction and overdose death rates that are not explicitly designed to also improve racial/ethnic inequalities will often unintentionally end up worsening them. Well-funded community-based programs, with Black and Native leadership, providing harm reduction resources, naloxone, and medications for opioid use disorder in the context of comprehensive, culturally appropriate healthcare and other services, represent the highest priority interventions to decrease inequalities.

Policy solutions to eliminate racial and ethnic child health disparities in the USA.

Societal systems act individually and in combination to create and perpetuate structural racism through both policies and practices at the local, state, and federal levels, which, in turn, generate racial and ethnic health disparities. Both current and historical policy approaches across multiple sectors-including housing, employment, health insurance, immigration, and criminal legal-have the potential to affect child health equity. Such policies must be considered with a focus on structural racism to understand which have the potential to eliminate or at least attenuate disparities. Policy efforts that do not directly address structural racism will not achieve equity and instead worsen gaps and existing disparities in access and quality-thereby continuing to perpetuate a two-tier system dictated by racism. In Paper 2 of this Series, we build on Paper 1's summary of existing disparities in health-care delivery and highlight policies within multiple sectors that can be modified and supported to improve health equity, and, in so doing, improve the health of racially and ethnically minoritised children.
