Comparison of Hospital Outcomes for Patients Treated by Allopathic Versus Osteopathic Hospitalists : An Observational Study.

BACKGROUND: The United States has 2 types of degree programs that educate physicians: allopathic and osteopathic medical schools. OBJECTIVE: To determine whether quality and costs of care differ between hospitalized Medicare patients treated by allopathic or osteopathic physicians. DESIGN: Retrospective observational study. SETTING: Medicare claims data. PATIENTS: 20% random sample of Medicare fee-for-service beneficiaries hospitalized with a medical condition during 2016 to 2019 and treated by hospitalists. MEASUREMENTS: The primary outcome was 30-day patient mortality. The secondary outcomes were 30-day readmission, length of stay (LOS), and health care spending (Part B spending). Multivariable regression models adjusted for patient and physician characteristics and their hospital-level averages (to effectively estimate differences within hospitals) were estimated. RESULTS: Of 329 510 Medicare admissions, 253 670 (77.0%) and 75 840 (23.0%) received care from allopathic and osteopathic physicians, respectively. The results can rule out important differences in quality and costs of care between allopathic versus osteopathic physicians for patient mortality (adjusted mortality, 9.4% for allopathic physicians vs. 9.5% [reference] for osteopathic hospitalists; average marginal effect [AME], -0.1 percentage point [95% CI, -0.4 to 0.1 percentage point]; P = 0.36), readmission (15.7% vs. 15.6%; AME, 0.1 percentage point [CI, -0.4 to 0.3 percentage point; P = 0.72), LOS (4.5 vs. 4.5 days; adjusted difference, -0.001 day [CI, -0.04 to 0.04 day]; P = 0.96), and health care spending ($1004 vs. $1003; adjusted difference, $1 [CI, -$8 to $10]; P = 0.85). LIMITATION: Data were limited to elderly Medicare patients hospitalized with medical conditions. CONCLUSION: The quality and costs of care were similar between allopathic and osteopathic hospitalists when they cared for elderly patients and worked as the principal physician in a team of health care professionals that often included other allopathic and osteopathic physicians.

Comparison of Patient Outcomes of Surgeons Who Are US Versus International Medical Graduates.

OBJECTIVE: The aim of this study was to compare patient outcomes between International Medical Graduate (IMG) versus US medical graduate (USMG) surgeons. SUMMARY BACKGROUND DATA: One in 7 surgeons practicing in the US graduated from a foreign medical school. However, it remains unknown whether patient outcomes differ between IMG versus USMG surgeons. METHODS: Using 20% random sample of Medicare fee-for-service beneficiaries aged 65 to 99 years who underwent 1 of 13 common nonelective surgical procedures (as a "natural experiment" as surgeons are less likely to select patients in this context) in 2011 to 2014 (638,973 patients treated by 37,221 surgeons for the mortality analysis), we compared operative mortality, complications, and length of stay (LOS) between IMG and USMG surgeons, adjusting for patient and surgeon characteristics and hospital-specific fixed effects (effectively comparing IMG and USMG surgeons within the same hospital). We also conducted stratified analyses by patients' severity of illness and procedure type. RESULTS: We found no evidence that patient outcomes differ between IMG and USMG surgeons for operative mortality [adjusted mortality, 7.3% for IMGs vs 7.3% for USMGs; adjusted odds ratio (aOR), 1.01; 95% confidence interval (CI), 0.96-1.05; P = 0.79], complication rate (adjusted complication rate, 0.6% vs 0.6%; aOR, 0.95; 95% CI, 0.85-1.06; P = 0.43), and LOS (adjusted LOS, 6.6 days vs 6.6 days; adjusted difference, +0.02 days; 95% CI, -0.05 to +0.08; P = 0.54). We also found no difference when we stratified by severity of illness and procedures. CONCLUSION: Using national data of Medicare beneficiaries who underwent common surgical procedures, we found no evidence that outcomes differ between IMG and USMG surgeons.

Sex differences in academic rank in allergy/immunology.

BACKGROUND: Female physicians are significantly less likely than male physicians to be full professors, even after accounting for age, experience, specialty, and measures of research and clinical productivity. OBJECTIVE: We sought to evaluate sex differences in academic rank in the allergy and immunology workforce. METHODS: We used a cross-sectional physician data set containing the allergist's sex, age, years since residency, faculty appointment, authored publications, National Institutes of Health (NIH) funding, clinical trial investigation, and Medicare reimbursement to investigate sex differences in the academic allergy and immunology workforce using multilevel logistic regression models. RESULTS: Among 507 academic allergists (9.3% of practicing US allergists in 2014), 323 (63.7%) were men, and 184 (36.3%) were women. Female allergists were younger (47.9 vs 56.9 years, P < .001), had fewer total (12.5 vs 28.7, P < .001) and first/last author (8.0 vs 21.5, P < .001) average publications, were less likely to have NIH funding (13.0% vs 23.5%, P = .004), were less frequently a clinical trial investigator (10.3% vs 16.1%, P = .07), and generated less average annual Medicare revenue ($44,000 vs $23,000, P = .10). Of 152 (30.0%) full professors, 126 (82.9%) were male, and 26 (17.0%) were female. After multivariable adjustment, rates of full professorship among female and male allergists were not significantly different (absolute adjusted difference for female vs male allergists, 6.0%; 95% CI, -8.3% to 20.2%). CONCLUSIONS: Among allergists with US medical school faculty appointments, men and women were similarly likely to be full professors after accounting for factors influencing promotion. Underlying differences in research productivity and NIH funding not explained by age differences alone warrant additional investigation.

Association between physician age and patterns of end-of-life care among older Americans.

BACKGROUND: End-of-life (EOL) care patterns may differ by physician age given differences in how physicians are trained or changes associated with aging. We sought to compare patterns of EOL care delivered to older Americans according to physician age. METHODS: We conducted a cross-sectional study of a 20% sample of Medicare fee-for-service beneficiaries aged ≥66 years who died in 2016-2019 (n = 487,293). We attributed beneficiaries to the physician who had >50% of primary care visits during the last 6 months of life. We compared beneficiary-level outcomes by physician age (<40, 40-49, 50-59, or ≥60) in two areas: (1) advance care planning (ACP) and palliative care; and (2) high-intensity care at the EOL. RESULTS: Beneficiaries attributed to younger physicians had slightly higher proportions of billed ACP (adjusted proportions, 17.1%, 16.1%, 15.5%, and 14.0% for physicians aged <40, 40-49, 50-59, and ≥60, respectively; p-for-trend adjusted for multiple comparisons <0.001) and palliative care counseling or hospice use in the last 180 days of life (64.5%, 63.6%, 61.9%, and 60.8%; p-for-trend <0.001). Similarly, physicians' younger age was associated with slightly lower proportions of emergency department visits (57.4%, 57.0%, 57.4%, and 58.1%; p-for-trend <0.001), hospital admissions (51.2%, 51.1%, 51.4%, and 52.1%; p-for-trend <0.001), intensive care unit admissions (27.8%, 27.9%, 28.2%, and 28.3%; p-for-trend = 0.03), or mechanical ventilation or cardiopulmonary resuscitation (14.2, 14.9%, 15.2%, and 15.3%; p-for-trend <0.001) in the last 30 days of life, and in-hospital death (20.2%, 20.6%, 21.3%, and 21.5%; p-for-trend <0.001). CONCLUSIONS: We found that differences in patterns of EOL care between beneficiaries cared for by younger and older physicians were small, and thus, not clinically meaningful. Future research is warranted to understand the factors that can influence patterns of EOL care provided by physicians, including initial and continuing medical education.

Association between physicians' geriatric training and patterns of end-of-life care delivered to persons with dementia.

BACKGROUND: Geriatric training is designed to prepare physicians to meet the complex needs of older adults, including persons with dementia at the end-of-life (EOL) stage. We sought to compare patterns of EOL care delivered to persons with dementia between physicians with versus without geriatric training. METHODS: We conducted a cross-sectional study of a 20% random sample of fee-for-service Medicare beneficiaries with dementia who died in 2016-2018 (n = 99,631). We attributed beneficiaries to a physician who had the largest number of primary care visits during the last 6 months of life and determined whether the physician was trained in geriatrics. Our outcome measures included: (i) advance care planning (ACP) and palliative care (e.g., ACP, hospice enrollment in the last 90 days of life), and (ii) high-intensity EOL care (e.g., emergency department visits or hospital admissions in the last 30 days of life). RESULTS: Beneficiaries with dementia under the care of physicians with geriatric training had a higher proportion of ACP (adjusted proportion, 15.8% vs. 13.0%; p < 0.001 after accounting for multiple comparisons), palliative care counseling (22.4% vs. 20.9%; p = 0.01), and hospice enrollment (63.7% vs. 60.6%; p < 0.001). Geriatric training was also associated with a lower proportion of emergency department visits (55.1% vs. 59.1%; p < 0.001), hospital admissions (48.8% vs. 52.3%; p < 0.001), ICU admissions (24.9% vs. 27.4%; p < 0.001), use of mechanical ventilation (11.2% vs. 13.0%; p < 0.001), and use of cardiopulmonary resuscitation (2.1% vs. 2.4%; p = 0.03) in the last 30 days of life. There was no evidence that the placement of feeding tubes differed between the two groups. CONCLUSIONS: Physicians' geriatric training was associated with the receipt of more ACP and palliative care and less intensive EOL care among persons with dementia. Provision of geriatric training for physicians may have the potential to improve the quality of EOL care delivered to persons with dementia.

Multispecialty Physician Online Survey Reveals That Burnout Related to Adverse Event Involvement May Be Mitigated by Peer Support.

OBJECTIVES: Involvement in adverse events can negatively impact physician well-being. Because burnout is increasingly recognized as a threat to patient safety, we examined the relationship between physician adverse event involvement and burnout as well as facilitators and barriers to support among physicians experiencing burnout. METHODS: We surveyed physicians in the United States who are members of the networking platform, Doximity. We conducted quantitative and qualitative analyses investigating experiences with adverse events, the impact of adverse events, the type of support the physician sought and received after the event, and burnout. RESULTS: Across specialties, involvement in an adverse event and burnout was common. Most respondents involved in an adverse event experienced emotional impact, but only a minority received support. Those reporting that the error resulted in emotional impact were more likely to experience burnout (adjusted odds ratio, 1.90; 95% confidence interval, 1.18-3.07); this association was mitigated by the most common form of support sought, peer support (adjusted odds ratio for burnout among those who received peer support versus those who did not, 0.65; 95% confidence interval, 0.52-0.82). Barriers to support after an adverse event include punitive culture and systems factors such as administrative bureaucracy. Facilitators that emerged include peer, professional, and spiritual support, mentorship, helping others, the learning environment, and improved/flexible working hours. CONCLUSIONS: Physicians who experienced emotional repercussions from adverse events were more likely to report burnout compared with those who did not. Respondents proposed barriers and facilitators to support that have not been widely implemented. Peer support may help mitigate physician burnout related to adverse events.

Physician Compensation In Physician-Owned And Hospital-Owned Practices.

Physician practices are increasingly being acquired by hospitals and health systems. Despite evidence that this type of vertical integration is profitable for hospitals, the association between these acquisitions and the incomes of physicians in the acquired practices is unknown. We combined national survey data on physician practice ownership with data on physician income to examine whether hospital or health system ownership of physician practices was associated with differences in physician income during 2014-18. During the study period, hospital and health system ownership of physician practices increased by 89.2 percent, from 24.1 percent to 45.6 percent of all physicians in our sample. Among physician practices overall, vertical integration with hospitals or health systems was associated with, on average, 0.8 percent lower income compared with independent physicians after multivariable adjustment. In analyses by physician specialty, vertical integration of physician practices with hospitals or health systems was associated with lower income for nonsurgical specialists, no difference in income for primary care physicians, and slightly higher income for surgical specialists. Although vertical integration of physician practices is a rapidly growing trend, physicians might not directly benefit financially.

Female Physicians Earn An Estimated $2 Million Less Than Male Physicians Over A Simulated 40-Year Career.

Differences in income between male and female academic physicians are well known, but differences for community physicians and career differences in income have not been quantified. We used earnings data from 80,342 full-time US physicians to estimate career differences in income between men and women. The differences in annual income between male and female physicians that we observed in our simulations increased most rapidly during the initial years of practice. Over the course of a simulated forty-year career, male physicians earned an average adjusted gross income of $8,307,327 compared with an average of $6,263,446 for female physicians-an absolute adjusted difference of $2,043,881 and relative difference of 24.6 percent. Gender differences in career earnings were largest for surgical specialists ($2.5 million difference), followed by nonsurgical specialists ($1.6 million difference) and primary care physicians ($0.9 million difference). These findings imply that over the course of a career, female US physicians were estimated to earn, on average, more than $2 million less than male US physicians after adjustment for factors that may otherwise explain observed differences in income, such as hours worked, clinical revenue, practice type, and specialty.

The Association Between Physician Gender and Career Advancement Among Academic Rheumatologists in the United States.

OBJECTIVE: To determine the potential association between physician gender and academic advancement among US rheumatologists. METHODS: We performed a nationwide, cross-sectional study of all rheumatologists practicing in the US in 2014 using a comprehensive database of all licensed physicians. Among academic rheumatologists, we estimated gender differences in faculty rank, adjusting for differences in physician age, years since residency graduation, publications, National Institutes of Health (NIH) grants, registered clinical trials, and appointment at a top 20 medical school using a multivariate logistic regression model. We also estimated gender differences in leadership positions (i.e., division director and fellowship program director). RESULTS: Among 6,125 total practicing rheumatologists, 941 (15%) had academic faculty appointments in 2014. Women academic rheumatologists (41.4%) were younger and had completed residency more recently than men. Women had fewer total publications, publications on which they were the first or last author, and NIH grants. In fully adjusted analyses, women were less likely to be full or associate professors than men, with an adjusted odds ratio (OR) of 0.78 (95% confidence interval [95% CI] 0.62-0.99]). Women in rheumatology had similar odds as men of being a fellowship program director or division director (adjusted OR 0.99 [95% CI 0.69-1.43] and adjusted OR 0.96 [95% CI 0.66-1.41], respectively). CONCLUSION: Among academic rheumatologists, women are less likely than men to be full or associate professors but have similar odds of being fellowship program directors or division directors, when adjusting for several factors known to influence faculty promotion. These differences suggest barriers to academic promotion despite representation in leadership positions within rheumatology divisions.

Practice composition and sex differences in physician income: observational study.

OBJECTIVE: To assess whether differences in income between male and female physicians vary according to the sex composition of physician practices. DESIGN: Retrospective observational study. SETTING: US national survey of physician salaries, 2014-18. PARTICIPANTS: 18 802 physicians from 9848 group practices (categorized according to proportion of male physicians ≤50%, >50-75%, >75-90%, and >90%). MAIN OUTCOME MEASURES: Sex differences in physician income in relation to the sex composition of physician practices after multivariable adjustment for physician specialty, years of experience, hours worked, measures of clinical workload, practice type, and geography. RESULTS: Among 11 490 non-surgical specialists, the absolute adjusted sex difference in annual income (men versus women) was $36 604 (£29 663; €32 621) (95% confidence interval $24 903 to $48 306; 11.7% relative difference) for practices with 50% or less of male physicians compared with $91 669 ($56 587 to $126 571; 19.9% relative difference) for practices with at least 90% of male physicians (P=0.03 for difference). Similar findings were observed among surgical specialists (n=3483), with absolute adjusted sex difference in annual income of $46 503 ($42 198 to $135 205; 10.2% relative difference) for practices with 50% or less of male physicians compared with $149 460 ($86 040 to $212 880; 26.9% relative difference) for practices with at least 90% of male physicians (P=0.06 for difference). Among primary care physicians (n=3829), sex differences in income were not related to the proportion of male physicians in a practice. CONCLUSIONS: Among both non-surgical and surgical specialists, sex differences in income were largest in practices with the highest proportion of male physicians, even after detailed adjustment for factors that might explain sex differences in income.

Gender Differences in Faculty Rank Among Academic Emergency Physicians in the United States.

BACKGROUND: The purpose of this study was to complete a comprehensive analysis of gender differences in faculty rank among U.S. emergency physicians that reflected all academic emergency physicians. METHODS: We assembled a comprehensive list of academic emergency medicine (EM) physicians with U.S. medical school faculty appointments from Doximity.com linked to detailed information on physician gender, age, years since residency completion, scientific authorship, National Institutes of Health (NIH) research funding, and participation in clinical trials. To estimate gender differences in faculty rank, multivariable logistic regression models were used that adjusted for these factors. RESULTS: Our study included 3,600 academic physicians (28%, or 1,016, female). Female emergency physicians were younger than their male colleagues (mean [±SD] age was 43.8 [±8.7] years for females and 47.4 [±9.9] years for males [p < 0.001]), had fewer years since residency completion (12.4 years vs. 15.6 years, p < 0.001), had fewer total and first/last author publications (4.7 vs. 8.6 total publications, p < 0.001; 4.3 vs. 7.1 first or last author publications, p < 0.001), and were less likely to be principal investigators on NIH grants (1.2% vs. 2.9%, p = 0.002) or clinical trials (1.8% vs. 4.4%, p < 0.001). In unadjusted analysis, male physicians were more likely than female physicians to hold the rank of associate or full professor versus assistant professor (13.7 percentage point difference, p < 0.001), a relationship that persisted after multivariable adjustment (5.5 percentage point difference, p = 0.001). CONCLUSIONS: Female academic EM physicians are less likely to hold the rank of associate or full professor compared to male physicians even after detailed adjustment for other factors that may influence faculty rank.

Golf habits among physicians and surgeons: observational cohort study.

OBJECTIVES: To examine patterns of golfing among physicians: the proportion who regularly play golf, differences in golf practices across specialties, the specialties with the best golfers, and differences in golf practices between male and female physicians. DESIGN: Observational study. SETTING: Comprehensive database of US physicians linked to the US Golfing Association amateur golfer database. PARTICIPANTS: 41 692 US physicians who actively logged their golf rounds in the US Golfing Association database as of 1 August 2018. MAIN OUTCOME MEASURES: Proportion of physicians who play golf, golf performance (measured using golf handicap index), and golf frequency (number of games played in previous six months). RESULTS: Among 1 029 088 physicians, 41 692 (4.1%) actively logged golf scores in the US Golfing Association amateur golfer database. Men accounted for 89.5% of physician golfers, and among male physicians overall, 5.5% (37 309/683 297) played golf compared with 1.3% (4383/345 489) among female physicians. Rates of golfing varied substantially across physician specialties. The highest proportions of physician golfers were in orthopedic surgery (8.8%), urology (8.1%), plastic surgery (7.5%), and otolaryngology (7.1%), whereas the lowest proportions were in internal medicine and infectious disease (<3.0%). Physicians in thoracic surgery, vascular surgery, and orthopedic surgery were the best golfers, with about 15% better golf performance than specialists in endocrinology, dermatology, and oncology. CONCLUSIONS: Golfing is common among US male physicians, particularly those in the surgical subspecialties. The association between golfing and patient outcomes, costs of care, and physician wellbeing remain unknown.
