PurposeIndependent Academic Medical Centers (IAMCs) comprise one-third of U.S. general surgery training programs. It is unclear whether IAMCs offer qualitatively or quantitatively different operative experiences than the national cohort. We analyzed a large representative sample of IAMCs to compare operative volume and variety, with a focus on low-volume procedures.MethodsAccreditation Council for Graduate Medical Education Program Case Reports from 27 IAMCs were collected and analyzed for 3 academic years (2012-2015). IAMCs were compared to the national cohort for specific defined category volumes and selected low-volume cases. One-sample two-way t-tests were calculated comparing IAMC totals to national program averages.ResultsIAMCs had a median of 3 chief residents per year (range: 1-6). IAMCs reported significantly more "total major" procedures in 2013-2014 (p = 0.046). Other case totals were statistically similar between IAMCs and the national cohort for "total major", "surgeon chief", "surgeon junior", and "teaching assistant" cases. In 2013-2014, IAMCs reported more laparoscopic complex (138.3 vs. 110.6, p = 0.010) and alimentary tract cases (276.5 vs. 253.5, p = 0.019). IAMC esophagogastroduodenoscopy case totals were higher in 2013-2014 (55.9 vs. 41, p = 0.038) and 2014-2015 (47.8 vs. 41, p = 0.047). IAMCs had fewer pancreas cases than the national cohort in all three years by about three cases per resident (p ≤ 0.026). In 2012-2013 IAMCs reported fewer (by about one) esophagectomy, gastrectomy, and abdominal perineal resections. No differences were observed in the following selected procedures: open common bile duct exploration, inguinal hernia, laparoscopic appendectomy, laparoscopic cholecystectomy, and colonoscopy.ConclusionsThe IAMCs studied appear to provide equivalent exposure to specific subcategories mandated by the Accreditation Council for Graduate Medical Education and American Board of Surgery. Graduates of IAMCs gain similar operative experience in low-volume, defined categories when compared to the national cohort. Certain specific cases subject to regionalization pressure are less well represented among IAMCs. This has important implications for medical students applying to surgery residency.Copyright © 2017 Association of Program Directors in Surgery. Published by Elsevier Inc. All rights reserved.
