On the Eve of Integration: Community and Affiliated Residency Programs Pave the Way Towards the Assimilation of...

The 2020 match integrated former osteopathic and allopathic residency programs under single Graduate Medical Education accreditation. We describe the composition of general surgery residency programs prior to the 2020 integration and provide a baseline to monitor future progress.

Retrospective, cross-sectional data provided by the Association of American Medical Colleges for the 2018 academic year were analyzed. Descriptive analyses were used to summarize the characteristics of residents by program type and program location. Logistic regression was used to estimate factors associated with the presence of osteopathic (DO) residents. An alpha of 0.05 defined statistical significance.

Data were collected and analyzed at a United States osteopathic medical school.

All civilian surgery residencies that approved the 2018 Program Survey.

Out of 285 programs, the percentages with at least one DO resident were significantly different among university (44.0%), university-affiliated (62.7%) and community (78.4%) programs (p < 0.001). DO residents made up 41.4% of community residents, 13.3% of university-affiliated residents, and 2.8% of university residents (p < 0.001). A significant regional difference was observed, as DO residents made up 16.9% of residents in the central region, compared to 10.4% in the northeast, 7.0% in the south and 8.9% in the west (p = 0.004). The logistic regression analysis found that the presence of DO residents at a program was significantly related to the type of program (Affiliated vs University OR = 3.1, 95% CI 1.5-6.5; Community vs University OR = 5.2, 95% CI 1.9-14.4) and the presence of DO faculty (OR = 2.7, 95% CI 1.6-4.8) (all p < 0.05).

We observed significant differences in the presence of DO residents in different program types. As surgical education transitions to single accreditation, this study identifies opportunities for greater integration between osteopathic and allopathic surgery training programs.
