Affirmative Action Bans and Enrollment of Students From Underrepresented Racial and Ethnic Groups in U.S. Public Medical Schools.

BACKGROUND: The percentage of U.S. physicians who identify as being from an underrepresented racial or ethnic group remains low relative to their proportion in the U.S. population. How this percentage may have been affected by state bans on affirmative action in public postsecondary institutions has received relatively little attention. OBJECTIVE: To examine the association between state affirmative action bans and percentage of enrollment in U.S. public medical schools from underrepresented racial and ethnic groups. DESIGN: Event study comparing public medical schools in states that implemented affirmative action bans with those in states without bans. SETTING: U.S. public medical schools. PARTICIPANTS: 21 public medical schools in 8 states with affirmative action bans matched to 32 public medical schools in 24 states without bans from 1985 to 2019. MEASUREMENTS: Percentage of total enrollment from racial and ethnic groups underrepresented in medicine (Black, Hispanic, American Indian or Alaska Native, and Native Hawaiian or other Pacific Islander). RESULTS: The percentage of enrollment from underrepresented racial and ethnic groups was 14.8% in U.S. public medical schools in the year before ban implementation in states with bans. The adjusted percentage of underrepresented students in ban schools decreased by 4.8 percentage points (95% CI, -6.3 to -3.2 percentage points) 5 years after ban implementation relative to the year before implementation, whereas the adjusted percentage in control schools increased by 0.7 percentage point (CI, -0.1 to 1.6 percentage points), for a relative difference, or difference-in-differences estimate, of -5.5 percentage points (CI, -7.1 to -3.9 percentage points). LIMITATION: Inability to account for the effect of these bans on undergraduate enrollment. CONCLUSION: State affirmative action bans were associated with significant reductions in the percentage of students in U.S. public medical schools from underrepresented racial and ethnic groups. PRIMARY FUNDING SOURCE: None.

The Influence of the Availability Heuristic on Physicians in the Emergency Department.

STUDY OBJECTIVE: Heuristics, or rules of thumb, are hypothesized to influence the care physicians deliver. One such heuristic is the availability heuristic, under which assessments of an event's likelihood are affected by how easily the event comes to mind. We examined whether the availability heuristic influences physician testing in a common, high-risk clinical scenario: assessing patients with shortness of breath for the risk of pulmonary embolism. METHODS: We performed an event study from 2011 to 2018 of emergency physicians caring for patients presenting with shortness of breath to 104 Veterans Affairs (VA) hospitals. Our measures were physician rates of pulmonary embolism testing (D-dimer and/or computed tomography scan) for subsequent patients after having a patient visit with a pulmonary embolism discharge diagnosis, hypothesizing that physician rates of pulmonary embolism testing would increase after having a recent patient visit with a pulmonary embolism diagnosis due to the availability heuristic. RESULTS: The sample included 7,370 emergency physicians who had 416,720 patient visits for shortness of breath. The mean rate of pulmonary embolism testing was 9.0%. For physicians who had a recent patient visit with a pulmonary embolism diagnosis, their rate of pulmonary embolism testing for subsequent patients increased by 1.4 percentage points (95% confidence interval 0.42 to 2.34) in the 10 days after, which is approximately 15% relative to the mean rate of pulmonary embolism testing. We failed to find statistically significant changes in rates of pulmonary embolism testing in the subsequent 50 days following these first 10 days. CONCLUSION: After having a recent patient visit with a pulmonary embolism diagnosis, physicians increase their rates of pulmonary embolism testing for subsequent patients, but this increase does not persist. These results provide large-scale evidence that the availability heuristic may play a role in complex testing decisions.

Evaluation and Treatment Patterns of New Low Back Pain Episodes for Elderly Adults in the United States, 2011-2014.

INTRODUCTION: New low back pain (LBP) is a common outpatient complaint. Little is known about how care is delivered over the course of a year to patients who develop new LBP and whether such care patterns are guideline-concordant. METHODS: This retrospective analysis included Medicare claims of 162,238 opioid-naïve beneficiaries with new LBP from January 1, 2011, through December 31, 2014. Simple rates of modality use [computed tomography and magnetic resonance imaging (advanced imaging), physical therapy (PT), opioid and nonopioid medications] and percentiles (5th percentile, 25th percentile, median, 75th percentile, and 95th percentile) were reported. RESULTS: Within the first year, 29.4% [95% confidence interval (CI), 29.1-29.8] of patients with ≥2 visits for new LBP received advanced imaging, and 48.4% (95% CI, 47.7-49.0) of these patients received advanced imaging within 6 weeks of the first visit; 17.3% (95% CI, 17.1-17.6) of patients with ≥2 visits received PT; 42.2% (95% CI, 41.8-42.5) of patients with ≥2 visits received non-steroidal anti-inflammatory drugs (NSAIDs), 16.9% (95% CI, 16.6-17.1) received a muscle relaxant, and 26.2% (95% CI, 25.9-26.6) received tramadol; 32.3% (95% CI, 31.9-32.6) of patients with ≥2 visits received opioids; 52.4% (95% CI, 51.7-53.0) of these patients had not received a prescription NSAID, and 82.2% (95% CI, 81.7-82.7) of these patients had not received PT. CONCLUSIONS: Many patients who develop new LBP receive guideline nonconcordant care such as early advanced imaging and opioids before other modalities like PT and prescription NSAIDs.

Racial and Ethnic Disparities in the Evaluation and Management of Pain in the Outpatient Setting, 2006-2015.

OBJECTIVE: Much is known about racial and ethnic disparities in receipt of opioids for pain in emergency departments. Less is known about such disparities in the evaluation and management of pain in the outpatient setting. METHODS: Using the nationally representative National Ambulatory Medical Care Survey (NAMCS), we estimated disparities in visit time with physicians and opioid receipt in the outpatient setting. We focused on patients whose reason for visiting was abdominal pain or back pain. Our sample included 4,764 white patients, 692 black patients, and 682 Hispanic patients. RESULTS: Back pain visits of Hispanic patients lasted 1.6 fewer minutes than those of white non-Hispanic patients (P = 0.04 for the difference). Black patients were 6.0% less likely than white patients to receive opioids for abdominal pain (P = 0.04 for the difference) and 7.1% less likely than white patients to receive opioids for back pain (P = 0.046 for the difference). Hispanic patients were 6.3% less likely than white patients to receive opioids for abdominal pain (P = 0.003 for the difference) and 14.8% less likely than white patients to receive opioids for back pain (P < 0.001 for the difference). Hispanic patients were more likely than white patients to receive nonopioids instead of opioids for both abdominal pain and back pain. Differences in opioid receipt did not narrow during the examined time period. CONCLUSIONS: Identifying causes of racial and ethnic disparities in the evaluation and treatment of pain in the outpatient setting is important to improving the health and function of patients.

Factors of U.S. Hospitals Associated with Improved Profit Margins: An Observational Study.

BACKGROUND: Hospitals face financial pressure from decreased margins from Medicare and Medicaid and lower reimbursement from consolidating insurers. OBJECTIVES: The objectives of this study are to determine whether hospitals that became more profitable increased revenues or decreased costs more and to examine characteristics associated with improved financial performance over time. DESIGN: The design of this study is retrospective analyses of U.S. non-federal acute care hospitals between 2003 and 2013. SUBJECTS: There are 2824 hospitals as subjects of this study. MAIN MEASURES: The main measures of this study are the change in clinical operating margin, change in revenues per bed, and change in expenses per bed between 2003 and 2013. KEY RESULTS: Hospitals that became more profitable had a larger magnitude of increases in revenue per bed (about $113,000 per year [95% confidence interval: $93,132 to $133,401]) than of decreases in costs per bed (about - $10,000 per year [95% confidence interval: - $28,956 to $9617]), largely driven by higher non-Medicare reimbursement. Hospitals that improved their margins were larger or joined a hospital system. Not-for-profit status was associated with increases in operating margin, while rural status and having a larger share of Medicare patients were associated with decreases in operating margin. There was no association between improved hospital profitability and changes in diagnosis related group weight, in number of profitable services, or in payer mix. Hospitals that became more profitable were more likely to increase their admissions per bed per year. CONCLUSIONS: Differential price increases have led to improved margins for some hospitals over time. Where significant price increases are not possible, hospitals will have to become more efficient to maintain profitability.

The impact of managed care contracting on physicians.

BACKGROUND: Prior literature suggests that the fragmented U.S. health care system places a large administrative burden on physicians. Less is known about how this burden varies with physician contracting practices. OBJECTIVE: To assess the extent to which physician practice outcomes vary with the number of managed care contracts held or the availability of such contracts. DESIGN, PARTICIPANTS, AND MAIN MEASURES: We perform secondary data analyses of the first four rounds of the nationally representative Community Tracking Study Physician Survey (1996-2005), which includes 36,340 physicians (21,567 PCPs [primary care physicians] and 14,773 specialists) across the four survey periods. Our measures include reported hours in patient care, share of hours outside patient care, adequacy of time with patients, career satisfaction, and income. RESULTS: Doctors who contract with more plans report spending more time in patient care (per 11 additional contracts, about 30 min per week for PCPs and 20 min per week for specialists), report spending a modestly larger share of their time outside patient care (per 11 additional contracts, about 10 min per week for PCPs and specialists), are slightly more likely to report inadequate time with patients (odds ratio 1.005 per additional contract for PCPs), and earn higher incomes (per 11 additional contracts, about 3 % more per year for specialists). CONCLUSIONS: Contracting opportunities confer significant benefits on physicians, although they do add modest costs in terms of time spent outside patient care and lower adequacy of time with patients. Simplifications that reduce the administrative burden of contracting may improve care by optimizing allocation of physician effort.

Changes in Prescription Drug and Health Care Use Over 9 Years After the Large Drug Price Increase for Colchicine.

Importance: Prescription drug prices are a leading concern among patients and policy makers. There have been large and sharp price increases for some drugs, but the long-term implications of large drug price increases remain poorly understood. Objective: To examine the association of the large 2010 price increase in colchicine, a common treatment for gout, with long-term changes in colchicine use, substitution with other drugs, and health care use. Design, Setting, and Participants: This retrospective cohort study examined MarketScan data from a longitudinal cohort of patients with gout with employer-sponsored insurance from 2007 through 2019. Exposures: The US Food and Drug Administration's discontinuation of lower-priced versions of colchicine from the market in 2010. Main Outcomes and Measures: Mean price of colchicine; use of colchicine, allopurinol, and oral corticosteroids; and emergency department (ED) and rheumatology visits for gout in year 1 and over the first decade of the policy (through 2019) were calculated. Data were analyzed between November 16, 2021, and January 17, 2023. Results: A total of 2 723 327 patient-year observations were examined from 2007 through 2019 (mean [SD] age of patients, 57.0 [13.8] years; 20.9% documented as female; 79.1% documented as male). The mean price per prescription of colchicine increased sharply from $11.25 (95% CI, $11.23-$11.28) in 2009 to $190.49 (95% CI, $190.07-$190.91) in 2011, a 15.9-fold increase, with the mean out-of-pocket price increasing 4.4-fold from $7.37 (95% CI, $7.37-$7.38) to $39.49 (95% CI, $39.42-$39.56). At the same time, colchicine use declined from 35.0 (95% CI, 34.6-35.5) to 27.3 (95% CI, 26.9-27.6) pills per patient in year 1 and to 22.6 (95% CI, 22.2-23.0) pills per patient in 2019. Adjusted analyses showed a 16.7% reduction in year 1 and a 27.0% reduction over the decade (P < .001). Meanwhile, adjusted allopurinol use rose by 7.8 (95% CI, 6.9-8.7) pills per patient in year 1, a 7.6% increase from baseline, and by 33.1 (95% CI, 32.6-33.7) pills per patient through 2019, a 32.0% increase from baseline over the decade (P < .001). Moreover, adjusted oral corticosteroid use exhibited no significant change in the first year, then increased by 1.5 (95% CI, 1.3-1.7) pills per patient through 2019, an 8.3% increase from baseline over the decade. Adjusted ED visits for gout rose by 0.02 (95% CI, 0.02-0.03) per patient in year 1, a 21.5% increase, and by 0.05 (95% CI, 0.04-0.05) per patient through 2019, a 39.8% increase over the decade (P < .001). Adjusted rheumatology visits for gout increased by 0.02 (95% CI, 0.02-0.03) per patient through 2019, a 10.5% increase over the decade (P < .001). Conclusions and Relevance: In this cohort study among individuals with gout, the large increase in colchicine prices in 2010 was associated with an immediate decrease in colchicine use that persisted over approximately a decade. Substitution with allopurinol and oral corticosteroids was also evident. Increased ED and rheumatology visits for gout over the same period suggest poorer disease control.

Evidence for Anchoring Bias During Physician Decision-Making.

Introduction: Cognitive biases are hypothesized to influence physician decision-making, but large-scale evidence consistent with their influence is limited. One such bias is anchoring bias, or the focus on a single-often initial-piece of information when making clinical decisions without sufficiently adjusting to later information. Objective: To examine whether physicians were less likely to test patients with congestive heart failure (CHF) presenting to the emergency department (ED) with shortness of breath (SOB) for pulmonary embolism (PE) when the patient visit reason section, documented in triage before physicians see the patient, mentioned CHF. Design, Setting, and Participants: In this cross-sectional study of 2011 to 2018 national Veterans Affairs data, patients with CHF presenting with SOB in Veterans Affairs EDs were included in the analysis. Analyses were performed from July 2019 to January 2023. Exposure: The patient visit reason section, documented in triage before physicians see the patient, mentions CHF. Main Outcomes and Measures: The main outcomes were testing for PE (D-dimer, computed tomography scan of the chest with contrast, ventilation/perfusion scan, lower-extremity ultrasonography), time to PE testing (among those tested for PE), B-type natriuretic peptide (BNP) testing, acute PE diagnosed in the ED, and acute PE ultimately diagnosed (within 30 days of ED visit). Results: The present sample included 108 019 patients (mean [SD] age, 71.9 [10.8] years; 2.5% female) with CHF presenting with SOB, 4.1% of whom had mention of CHF in the patient visit reason section of the triage documentation. Overall, 13.2% of patients received PE testing, on average within 76 minutes, 71.4% received BNP testing, 0.23% were diagnosed with acute PE in the ED, and 1.1% were ultimately diagnosed with acute PE. In adjusted analyses, mention of CHF was associated with a 4.6 percentage point (pp) reduction (95% CI, -5.7 to -3.5 pp) in PE testing, 15.5 more minutes (95% CI, 5.7-25.3 minutes) to PE testing, and 6.9 pp (95% CI, 4.3-9.4 pp) more BNP testing. Mention of CHF was associated with a 0.15 pp lower (95% CI, -0.23 to -0.08 pp) likelihood of PE diagnosis in the ED, although no significant association between the mention of CHF and ultimately diagnosed PE was observed (0.06 pp difference; 95% CI, -0.23 to 0.36 pp). Conclusions and Relevance: In this cross-sectional study among patients with CHF presenting with SOB, physicians were less likely to test for PE when the patient visit reason that was documented before they saw the patient mentioned CHF. Physicians may anchor on such initial information in decision-making, which in this case was associated with delayed workup and diagnosis of PE.

Racial and Ethnic Differences in Barriers Faced by Medical College Admission Test Examinees and Their Association With Medical School Application and Matriculation.

Importance: There has been disappointing progress in enrollment of medical students from racial and ethnic groups underrepresented in medicine, including American Indian or Alaska Native, Black, and Hispanic students. Barriers that may influence students interested in medicine are understudied. Objective: To examine racial and ethnic differences in barriers faced by students taking the Medical College Admission Test (MCAT). Design, Setting, and Participants: This cross-sectional study used survey data (surveys administered between January 1, 2015, to December 31, 2018) from MCAT examinees linked with application and matriculation data from the Association of American Medical Colleges. Data analyses were performed from November 1, 2021, to January 31, 2023. Main Variables and Outcomes: Main outcomes were medical school application and matriculation. Key independent variables reflected parental educational level, financial and educational barriers, extracurricular opportunities, and interpersonal discrimination. Results: The sample included 81 755 MCAT examinees (0.3% American Indian or Alaska Native, 21.3% Asian, 10.1% Black, 8.0% Hispanic, and 60.4% White; 56.9% female). There were racial and ethnic differences in reported barriers. For example, after adjustment for demographic characteristics and examination year, 39.0% (95% CI, 32.3%-45.8%) of American Indian or Alaska Native examinees, 35.1% (95% CI, 34.0%-36.2%) of Black examinees, and 46.6% (95% CI, 45.4%-47.9%) of Hispanic examinees reported having no parent with a college degree compared with 20.4% (95% CI, 20.0%-20.8%) of White examinees. After adjustment for demographic characteristics and examination year, Black examinees (77.8%; 95% CI, 76.9%-78.7%) and Hispanic examinees (71.3%; 95% CI, 70.2%-72.4%) were less likely than White examinees (80.2%; 95% CI, 79.8%-80.5%) to apply to medical school. Black examinees (40.6%; 95% CI, 39.5%-41.7%) and Hispanic examinees (40.2%; 95% CI, 39.0%-41.4%) were also less likely than White examinees (45.0%; 95% CI, 44.6%-45.5%) to matriculate at medical school. Examined barriers were associated with a lower likelihood of medical school application and matriculation (eg, examinees having no parent with a college degree had lower odds of applying [odds ratio, 0.65; 95% CI, 0.61-0.69] and matriculating [odds ratio, 0.63; 95% CI, 0.59-0.66]). Black-White and Hispanic-White disparities in application and matriculation were largely accounted for by differences in these barriers. Conclusions and Relevance: In this cross-sectional study of MCAT examinees, American Indian or Alaska Native, Black, and Hispanic students reported lower parental educational levels, greater educational and financial barriers, and greater discouragement from prehealth advisers than White students. These barriers may deter groups underrepresented in medicine from applying to and matriculating at medical school.

Inequities in surgical outcomes by race and sex in the United States: retrospective cohort study.

OBJECTIVE: To assess inequities in mortality by race and sex for eight common surgical procedures (elective and non-elective) across specialties in the United States. DESIGN: Retrospective cohort study. SETTING: US, 2016-18. PARTICIPANTS: 1 868 036 Black and White Medicare beneficiaries aged 65-99 years undergoing one of eight common surgeries: repair of abdominal aortic aneurysm, appendectomy, cholecystectomy, colectomy, coronary artery bypass surgery, hip replacement, knee replacement, and lung resection. MAIN OUTCOME MEASURE: The main outcome measure was 30 day mortality, defined as death during hospital admission or within 30 days of the surgical procedure. RESULTS: Postoperative mortality overall was higher in Black men (1698 deaths, adjusted mortality rate 3.05%, 95% confidence interval 2.85% to 3.24%) compared with White men (21 833 deaths, 2.69%, 2.65% to 2.73%), White women (21 847 deaths, 2.38%, 2.35% to 2.41%), and Black women (1631 deaths, 2.18%, 2.04% to 2.31%), after adjusting for potential confounders. A similar pattern was found for elective surgeries, with Black men showing a higher adjusted mortality (393 deaths, 1.30%, 1.14% to 1.46%) compared with White men (5650 deaths, 0.85%, 0.83% to 0.88%), White women (4615 deaths, 0.82%, 0.80% to 0.84%), and Black women (359 deaths, 0.79%, 0.70% to 0.88%). This 0.45 percentage point difference implies that mortality after elective procedures was 50% higher in Black men compared with White men. For non-elective surgeries, however, mortality did not differ between Black men and White men (1305 deaths, 6.69%, 6.26% to 7.11%; and 16 183 deaths, 7.03%, 6.92% to 7.14%, respectively), although mortality was lower for White women and Black women (17 232 deaths, 6.12%, 6.02% to 6.21%; and 1272 deaths, 5.29%, 4.93% to 5.64%, respectively). These differences in mortality appeared within seven days after surgery and persisted for up to 60 days after surgery. CONCLUSIONS: Postoperative mortality overall was higher among Black men compared with White men, White women, and Black women. These findings highlight the need to understand better the unique challenges Black men who require surgery face.

How physicians evaluate patients with dementia who present with shortness of breath.

BACKGROUND: Whether the presence of dementia in patients makes it difficult for physicians to assess the risk such patients might have for serious conditions such as pulmonary embolism (PE) is unknown. Our objective was to examine the differential association of four clinical factors (deep venous thrombosis (DVT)/PE, malignancy, recent surgery, and tachycardia) with PE testing for patients with dementia compared to patients without dementia. METHODS: We performed a cross-sectional study of emergency department (ED) visits to 104 Veterans Affairs (VA) hospitals from 2011 to 2018 by patients aged 60 years and over presenting with shortness of breath (SOB). Our outcomes were PE testing (CT scan and/or D-dimer) and subsequently diagnosed acute PE. RESULTS: The sample included 593,001 patient visits for SOB across 7124 ED physicians; 5.6% of the sample had dementia, and 10.6% received PE testing. Three of the four clinical factors examined had a lower association with PE testing for patients with dementia. For example, after taking into account that at baseline, physicians were 0.9 percentage points less likely to test patients with dementia than patients without dementia for PE, physicians were an additional 2.6 percentage points less likely to test patients with dementia who had tachycardia than patients without dementia who had tachycardia. We failed to find evidence that any clinical factor examined had a differentially lower association with a subsequently diagnosed acute PE for patients with dementia. CONCLUSIONS: Clinical factors known to be predictive of PE risk had a lower association with PE testing for patients with dementia compared to patients without dementia. These results may be consistent with physicians missing these clinical factors more often when evaluating patients with dementia, but also with physicians recognizing such factors but not using them in the decision-making process. Further understanding how physicians evaluate patients with dementia presenting with common acute symptoms may help improve the care delivered to such patients.

The association between hospital margins, quality of care, and closure or other change in operating status.

BACKGROUND: Hospitals face increased pressure to improve their quality of care in an environment of dwindling hospital payments. It is unclear whether lower hospital margins are associated with worse quality of care or closure. OBJECTIVE: To determine the association of hospital margins with quality of care and changes in operating status. DESIGN, SUBJECTS, AND MAIN MEASURES: We conducted an observational cross-sectional study analyzing hospitals' margin, quality of care (process quality, risk-adjusted readmission rates, and risk-adjusted mortality rates), and changes in operating status (rates of closure, merger and acquisition, and conversion to a critical access hospital) for 3,262 non-public U.S. hospitals with data from the Hospital Quality Alliance and Medicare Cost Reports. KEY RESULTS: Compared to those in the bottom 10% of operating margin, those in the top 10% had higher process quality (e.g. 95.3 vs. 93.7, p = 0.002 for acute myocardial infarction [AMI]) and lower readmission rates (e.g. 19.7% vs. 22.4%, p < 0.001 for AMI). We found no association between margins and mortality rates. Hospitals in the bottom 10% were more likely than those in the top 10% to close (5.7% vs. 2.0%), merge or become acquired (4.0% vs. 0.3%), or convert to a Critical Access Hospital (5.4% vs. 0.6%). Over 15% of hospitals in the lowest decile of hospital margin changed operating status in the subsequent year. CONCLUSIONS: Low hospital margins are associated with worse processes of care and readmission rates and with changes in operating status. We should monitor low-margin hospitals closely for declining quality of care.

The (paper) work of medicine: understanding international medical costs.

This paper draws on international evidence on medical spending to examine what the United States can learn about making its healthcare system more efficient. We focus primarily on understanding contemporaneous differences in the level of spending, generally from the 2000s. Medical spending differs across countries either because the price of services differs (for example, a coronary bypass surgery operation may cost more in the United States than in other countries) or because people receive more services in some countries than in others (for example, more bypass surgery operations). Within the price category, there are two further issues: whether factors earn different returns across countries and whether more clinical or administrative personnel are required to deliver the same care in different countries. We first present the results of a decomposition of healthcare spending along these lines in the United States and in Canada. We then delve into each component in more detail­administrative costs, factor prices, and the provision of care received­bringing in a broader range of international evidence when possible. Finally, we touch upon the organization of primary and chronic disease care and discuss possible gains in that area.
