Disparities in Guideline Concordant Statin Treatment in Individuals With Chronic Obstructive Pulmonary Disease.

Rationale: Cardiovascular disease (CVD) affects the prognosis of patients with chronic obstructive pulmonary disease (COPD). Black women with COPD have a disproportionate risk of CVD-related mortality, yet disparities in CVD prevention in COPD are unknown. Objectives: We aimed to identify race-sex differences in the receipt of statin treatment for CVD prevention, and whether these differences were explained by factors influencing health care utilization in the REasons for Geographic And Racial Differences in Stroke (REGARDS) COPD study sub-cohort. Methods: We conducted a cross-sectional analysis among REGARDS Medicare beneficiaries with COPD. Our primary outcome was the presence of statin on in-home pill bottle review among individuals with an indication. Prevalence ratios (PR) for statin treatment among race-sex groups compared to White men were estimated using Poisson regression with robust variance. We then adjusted for covariates previously shown to impact health care utilization. Results: Of the 2032 members within the COPD sub-cohort with sufficient data, 1435 participants (19% Black women, 14% Black men, 28% White women, and 39% White men) had a statin indication. All race-sex groups were less likely to receive statins than White men in unadjusted models. After adjusting for covariates that influence health care utilization, Black women (PR 0.76, 95% confidence interval [CI] 0.67 to 0.86) and White women (PR 0.84 95% CI 0.76 to 0.91) remained less likely to be treated compared to White men. Conclusions: All race-sex groups were less likely to receive statin treatment in the REGARDS COPD sub-cohort compared to White men. This difference persisted in women after controlling for individual health care utilization factors, suggesting structural interventions are needed.

African American race is associated with worse sleep quality in heavy smokers.

STUDY OBJECTIVES: To examine the association of self-identified race with sleep quality in heavy smokers. METHODS: We studied baseline data from 1965 non-Hispanic White and 462 African American participants from SPIROMICS with ≥ 20 pack-years smoking history. We first examined the Pittsburgh Sleep Quality Index's (PSQI) internal consistency and item-total correlation in a population with chronic obstructive pulmonary disease. We then used staged multivariable regression to investigate the association of race and sleep quality as measured by the PSQI) The first model included demographics, the second added measures of health status, and the third, indicators of socioeconomic status. We next explored the correlation between sleep quality with 6-minute walk distance and St. George's Respiratory Questionnaire score as chronic obstructive pulmonary disease-relevant outcomes. We tested for interactions between self-identified race and the most important determinants of sleep quality in our conceptual model. RESULTS: We found that the PSQI had good internal consistency and item-total correlation in our study population of heavy smokers with and without chronic obstructive pulmonary disease. African American race was associated with increased PSQI in univariable analysis and after adjustment for demographics, health status, and socioenvironmental exposures (P = .02; 0.44 95%CI: .06 to .83). Increased PSQI was associated with higher postbronchodilator forced expiratory volume in 1 second and lower household income, higher depressive symptoms, and female sex. We identified an interaction wherein depressive symptoms had a greater impact on PSQI score for non-Hispanic White than African American participants (P for interaction = .01). CONCLUSIONS: In heavy smokers, self-reported African American race is independently associated with worse sleep quality.

Race and Ethnicity in Pulmonary Function Test Interpretation: An Official American Thoracic Society Statement.

Current American Thoracic Society (ATS) standards promote the use of race and ethnicity-specific reference equations for pulmonary function test (PFT) interpretation. There is rising concern that the use of race and ethnicity in PFT interpretation contributes to a false view of fixed differences between races and may mask the effects of differential exposures. This use of race and ethnicity may contribute to health disparities by norming differences in pulmonary function. In the United States and globally, race serves as a social construct that is based on appearance and reflects social values, structures, and practices. Classification of people into racial and ethnic groups differs geographically and temporally. These considerations challenge the notion that racial and ethnic categories have biological meaning and question the use of race in PFT interpretation. The ATS convened a diverse group of clinicians and investigators for a workshop in 2021 to evaluate the use of race and ethnicity in PFT interpretation. Review of evidence published since then that challenges current practice and continued discussion concluded with a recommendation to replace race and ethnicity-specific equations with race-neutral average reference equations, which must be accompanied with a broader re-evaluation of how PFTs are used to make clinical, employment, and insurance decisions. There was also a call to engage key stakeholders not represented in this workshop and a statement of caution regarding the uncertain effects and potential harms of this change. Other recommendations include continued research and education to understand the impact of the change, to improve the evidence for the use of PFTs in general, and to identify modifiable risk factors for reduced pulmonary function.

Epidemiology of Sarcoidosis in U.S. Veterans from 2003 to 2019.

Rationale: United States veterans represent an important population to study sarcoidosis. Their unique history of environmental exposures, wide geographic distribution, and long-term enrollment in a single integrated healthcare system provides an unparalleled opportunity to understand the incidence, prevalence, and risk factors for sarcoidosis. Objectives: To determine the epidemiology, patient characteristics, geographic distribution, and associated risk factors of sarcoidosis among U.S. veterans. Methods: We used data from the Veterans Health Administration (VHA) electronic health record system between 2003 and 2019 to evaluate the annual incidence, prevalence, and geographic distribution of sarcoidosis (defined using the International Classification of Diseases codes). We used multivariate logistic regression to examine patient characteristics associated with sarcoidosis incidence. Results: Among more than 13 million veterans who received care through or paid for by the VHA, 23,747 (0.20%) incident diagnoses of sarcoidosis were identified. Compared with selected VHA control subjects using propensity score matching, veterans with sarcoidosis were more likely to be female (13.5% vs. 9.0%), of Black race (52.2% vs. 17.0%), and ever-tobacco users (74.2% vs. 64.5%). There was an increase in the annual incidence of sarcoidosis between 2004 and 2019 (from 38 to 52 cases/100,000 person-years) and the annual prevalence between 2003 and 2019 (from 79 to 141 cases/100,000 persons). In a multivariate logistic regression model, Black race (odds ratio [OR], 4.49; 95% confidence interval [CI], 4.33-4.65), female sex (OR, 1.64; 95% CI, 1.56-1.73), living in the Northeast compared with the western region (OR, 1.57; 95% CI, 1.48-1.67), history of tobacco use (OR, 1.36; 95% CI, 1.31-1.41), and serving in the Army, Air Force, or multiple branches compared with the Navy (OR, 1.08; 95% CI, 1.03-1.13; OR, 1.10; 95% CI, 1.04-1.17; OR, 1.27; 95% CI, 1.16-1.39, respectively) were significantly associated with incident sarcoidosis (P < 0.0001). Conclusions: The incidence and prevalence of sarcoidosis are higher among veterans than in the general population. Alongside traditionally recognized risk factors such as Black race and female sex, we found that a history of tobacco use within the Veterans Affairs population and serving in the Army, Air Force, or multiple service branches were associated with increased sarcoidosis risk.

Beta-blocker use in patients with chronic obstructive pulmonary disease: A systematic review: A systematic review of ßB in COPD.

Beta-blockers (ßB) are a frequently used class of medications. Although ßB have many indications, those related to cardiovascular disease are among the most common and important. However, in patients with chronic obstructive pulmonary disease (COPD), ßB are used less often due to concerns about an unfavorable impact on respiratory morbidity and mortality. We performed a systematic review to assess the safety of ßB in patients with COPD. We included a total of 2 randomized controlled trials and 28 observational studies. The majority found statistically significant reductions in mortality. The two higher quality observational studies reported increased mortality with ßB. The risk of COPD exacerbations was reduced in about half of the studies. Nonetheless, there were significant biases that confounded the results. The highest quality RCT found a significant increase in severe and very severe COPD exacerbations with ßB use. In conclusion, data on the safety of ßB in patients with COPD are conflicting. However, given higher quality evidence showed harm with their use, ßB should be prescribed with caution in patients with COPD, including patients with cardiac indication for ßB.

How Financial Aid Policy Shortchanges American Healthcare.

Issue: Medical school debt is increasing. This trend may reduce access to medical school at a time of historic recognition of the need for greater openness and diversity in medical education by disadvantaging candidates who are underrepresented in medicine. The effects of high education-related debt for medical school needs greater consideration. Evidence: The implementation staircase model is employed as lens for understanding the impact of debt on trainees who are underrepresented in medicine and the healthcare system overall. Higher debt burdens are associated with worse mental health outcomes and increased odds of attrition in medical school. Trainees cite debt as a concern in considering primary care careers. Those with greater debt are less likely to pursue or remain in academic careers. Implications: The current financial aid system's reliance on high debt burden undermines goals to improve the representation of underrepresented candidates in primary care and academic medicine. Alternative models requiring less debt could facilitate the creation of a more diverse workforce in healthcare.

Reconsidering the Utility of Race-Specific Lung Function Prediction Equations.

Rationale: African American individuals have worse outcomes in chronic obstructive pulmonary disease (COPD). Objectives: To assess whether race-specific approaches for estimating lung function contribute to racial inequities by failing to recognize pathological decrements and considering them normal. Methods: In a cohort with and at risk for COPD, we assessed whether lung function prediction equations applied in a race-specific versus universal manner better modeled the relationship between FEV1, FVC, and other COPD outcomes, including the COPD Assessment Test, St. George's Respiratory Questionnaire, computed tomography percent emphysema, airway wall thickness, and 6-minute-walk test. We related these outcomes to differences in FEV1 using multiple linear regression and compared predictive performance between fitted models using root mean squared error and Alpaydin's paired F test. Measurements and Main Results: Using race-specific equations, African American individuals were calculated to have better lung function than non-Hispanic White individuals (FEV1, 76.8% vs. 71.8% predicted; P = 0.02). Using universally applied equations, African American individuals were calculated to have worse lung function. Using Hankinson's Non-Hispanic White equation, FEV1 was 64.7% versus 71.8% (P < 0.001). Using the Global Lung Initiative's Other race equation, FEV1 was 70.0% versus 77.9% (P < 0.001). Prediction errors from linear regression were less for universally applied equations compared with race-specific equations when examining FEV1% predicted with the COPD Assessment Test (P < 0.01), St. George's Respiratory Questionnaire (P < 0.01), and airway wall thickness (P < 0.01). Although African American participants had greater adversity (P < 0.001), less adversity was only associated with better FEV1 in non-Hispanic White participants (P for interaction = 0.041). Conclusions: Race-specific equations may underestimate COPD severity in African American individuals.Clinical trial registered with www.clinicaltrials.gov (NCT01969344).

The Long-Term Effectiveness of Empathic Interventions in Medical Education: A Systematic Review.

The Association of American Medical Colleges recognizes that empathy is an important part of providing excellent patient care and lists empathy as a Core Entrustable Professional Attribute for physicians. This study is a review of the literature focusing on studies with an educational intervention to promote empathy and at least one year follow-up data. After reviewing the 4910 abstracts retrieved from PubMed, PsycInfo, Cochrane, Web of Science, CINAHL, and Embase; the coauthors selected 61 articles for full-text review and completed a medical education research study quality instrument (MERSQI) to ensure all selected studies scored at least 7 or above. Five studies from the US and seven international studies met our inclusion criteria and formed the basis for the study. Few longitudinal studies with a post-intervention follow-up exist to confirm or disprove the effectiveness and durability of empathy training. Of the published studies that do conduct long-term follow-up, study design and measures used to test empathy are inconsistent. Despite the high degree of heterogeneity, the overwhelming majority demonstrated declining empathy over time. Little evidence was identified to support the ability to augment the empathy of physician trainees in sustained fashion. A model is presented which explains the observed changes. Alternative solutions are proposed, including the selection of more prosocial candidates.

Communication training is inadequate: the role of deception, non-verbal communication, and cultural proficiency.

In this commentary, we argue that the limited experiential exposure of medical students to different cultures makes the instruction devoted to communication skills inadequate. The relationship of these dynamics to honesty in clinical encounters is explored. Absent significant experiential exposure to differing group cultures to counter the natural tendency to favor one's own, discrimination prevails. Knowledge or awareness of cultural differences does not necessarily equate to communication proficiency. Critically, interactions based on lived experience offer a deeper knowledge and understanding of culturally meaningful nuances than that imparted through other formats. Medical students' lack of experiential exposure to different cultures results in communication miscues. When the stakes are high, people detect those miscues diminishing trust in the doctor-patient relationship. Greater experiential cultural exposure will enhance the facility and use of culturally specific communication cues. At its core, the requisite transformation will require medical students to adapt to other cultures and greater representation by marginalized and stigmatized populations not only among the studentry but staff and faculty. The time is now to ensure that the physicians we produce can care for all Americans. What cannot be taught must be identified by the selection process. Competence with half the population is a failure for American medicine.

Higher serum vitamin D levels are associated with decreased odds of obstructive lung disease in the general population: an NHANES analysis (2007-2008 to 2009-2010).

BACKGROUND: Obstructive lung disease is a significant cause of morbidity and healthcare burden within the USA. A growing body of evidence has suggested that vitamin D levels can influence the course or incidence of obstructive lung disease. However, there is an insufficient previous investigation of this association. STUDY DESIGN AND METHODS: We used the National Health and Nutrition Examination Survey (NHANES) cycles 2007-2008 and 2009-2010 spirometry results of individuals aged 40 years and older to assess the association between serum 25-hydroxyvitamin D levels and obstructive lung disease, as defined by the American Thoracic Society using the lower limit of normal. We used stage multivariate survey-logistic regression. RESULTS: The final model included age, gender, body mass index, pack-years smoking history, season, income-to-poverty ratio and race/ethnicity. In the primary analysis using vitamin D as a continuous variable, there was no association between vitamin D levels and obstructive lung disease. We noted a trend between 'other Hispanic' self-identified race and serum vitamin D levels wherein higher levels were associated with higher odds of obstructive lung disease in this ethnicity, but not among other racial or ethnic groups (OR (95% CI)=1.40 (0.98 to 1.99), p=0.06). In a secondary analysis, when vitamin D was measured as a categorical variable, there was a significant association between the highest levels of serum vitamin D levels and lesser odds of obstructive lung disease (OR (95% CI)=0.77 [0.61 to 0.98], p=0.04). CONCLUSIONS: Higher serum vitamin D levels among adults are associated with decreased odds of obstructive lung disease in the general population. Results among non-Mexican Hispanic participants highlight the need for further research in minority populations. More work is needed to address the course and incidence of lung disease in the USA.

The dynamics of poverty, educational attainment, and the children of the disadvantaged entering medical school.

Approximately one-third of the US population lives at or near the poverty line; however, this group makes up less than 7% of the incoming medical students. In the United Kingdom, the ratio of those of the highest social stratum is 30 times greater than those of the lowest to receive admission to medical school. In an effort to address health disparities and improve patient care, the authors argue that significant barriers must be overcome for the children of the disadvantaged to gain admission to medical school. Poverty is intergenerational and multidimensional. Familial wealth affects opportunities and educational attainment, starting when children are young and compounding as they get older. In addition, structural and other barriers exist to these students pursuing higher education, such as the realities of financial aid and the shadow of debt. Yet the medical education community can take steps to better support the children of the disadvantaged throughout their education, so they are able to reach medical school. If educators value the viewpoints and life experiences of diverse students enriching the learning environment, they must acknowledge the unique contributions that the children of the disadvantaged bring and work to increase their representation in medical schools and the physician workforce. We describe who the disadvantaged are contrasted with the metrics used by medical school admissions to identify them. The consequences of multiple facets of poverty on educational attainment are explored, including its interaction with other social identities, inter-generational impacts, and the importance of wealth versus annual income. Structural barriers to admission are reviewed. Given the multi-dimensional and cumulative nature of poverty, we conclude that absent significant and sustained intervention, medical school applicants from disadvantaged backgrounds will remain few and workforce issues affecting the care patients receive will not be resolved. The role of physicians and medical schools and advocating for necessary societal changes to alleviate this dynamic are highlighted.
