RESUMO
OBJECTIVE: The aim of this study is to compare surgical outcomes of international medical graduates (IMGs) and United States medical graduates (USMGs). SUMMARY OF BACKGROUND DATA: IMGs represent 15% of practicing surgeons in the United States (US), and their training pathways often differ substantially from USMGs. To date, differences in the clinical outcomes between the 2 cohorts have not been examined. METHODS: Using a unique dataset linking AMA Physician Masterfile data with hospital discharge claims from Florida and New York (2008-2011), patients who underwent 1 of 32 general surgical operations were stratified by IMG and USMG surgeon status. Mortality, complications, and prolonged length of stay were compared between IMG and USMG surgeon status using optimal sparse network matching with balance. RESULTS: We identified 972,718 operations performed by 4581 surgeons (72% USMG, 28% IMG). IMG and USMG surgeons differed significantly in demographic (age, gender) and baseline training (years of training, university affiliation of training hospital) characteristics. USMG surgeons performed complex procedures (13.7% vs 11.1%, P < 0.01) and practiced in urban settings (79.4% vs 75.6%, P < 0.01) more frequently, while IMG surgeons performed a higher volume of studied operations (50.7â±â5.1 vs 57.8â±â8.4, P < 0.01). In the matched cohort analysis of 396,810 patients treated by IMG and USMG surgeons, rates of mortality (USMG: 2.2%, IMG: 2.1%; P < 0.001), complications (USMG: 14.5%, IMG: 14.3%; P = 0.032), and prolonged length of stay (pLOS) (USMG: 22.7%, IMG: 22.8%; P = 0.352) were clinically equivalent. CONCLUSION: Despite considerable differences in educational background, surgical training characteristics, and practice patterns, IMG and USMG-surgeons deliver equivalent surgical care to the patients whom they treat.

BACKGROUND: Studies of surgical outcomes can be confounded by operative complexity. Complexity is difficult to assess from claims data due to the absence of established measures, but information on additional procedures is typically available. We hypothesized that analyzing same-day procedures (SDPs) would provide a useful step toward including operative complexity in risk adjustment. STUDY DESIGN: Colon resections were identified in California, Florida, and New York (2008 to 2011). Same-day procedures were categorized using 6 definitions. In-hospital mortality and postoperative complications were examined. For all outcomes, we developed multivariable logistic regression models to measure the association between the SDP category and outcomes. RESULTS: Rates of SDP were 74.9% total, 69.5% surgical, 31.6% nonsurgical, 36.6% colon, 51.4% abdomen, and 34.3% other for the 215,041 colon resections examined. Mortality was associated with the inclusion of any SDP category in univariate (6.2% vs 1.7%; p < 0.001) and multivariable (odds ratio [OR] = 2.14; 95% CI, 1.99-2.30; p < 0.001) analysis. The association with mortality was high for nonsurgical (OR = 2.36; 95% CI, 2.26-2.46) and other (OR = 2.33; 95% CI, 2.23-2.43) procedures and moderate for surgical (OR = 1.45; 95% CI, 1.37-1.54) and colon (OR = 1.51; 95% CI, 1.44-1.57) procedures, but abdominal procedures were not independently associated with mortality (OR = 1.01; 95% CI, 0.97-1.06). The total number of SDPs was also associated with higher complication rates. CONCLUSIONS: The risk of complications and mortality associated with colectomy was increased among patients with SDPs and the magnitude of the association was dependent on the type and quantity of additional procedures. Information on SDPs might reflect a component of operative risk not typically captured and should be considered as a candidate variable for risk adjustment when using claims to compare outcomes across large cohorts.
