Abstract

Background: Surgical fixation of hip fractures is a common procedure at teaching hospitals with resident support and in community hospitals. Objective: We evaluated to what extent participation by residents in hip fracture fixation affects operative times or outcomes. Setting: Operations were performed by three surgeons who operate at a teaching hospital with resident support, and at a community hospital without residents in the same metropolitan area. Participants: We performed a retrospective analysis of operative time and early post-operative outcomes on a series of 314 patients with hip fractures (Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association A1-3, B1-3) treated with surgical fixation between April 2012 and March 2015; 177 patients at the community hospital, and 137 at the teaching hospital. Methods: Multivariate regression assessed the effect of hospital type, adjusting for age, gender, American Society of Anesthesiologist classification, and Charlson comorbidity index. Results: We found lower median operative time at the community hospital than the teaching hospital (46 minutes, 95% confidence interval [CI] = [43, 52] versus 75 minutes, 95% CI = [70, 81]) and lower estimated blood loss (177.3 mL, 95% CI=[158.6, 195.1] versus 234.8 mL, 95% CI = [196.4, 273.6]), but no differences in transfusion requirement, length of stay, or discharge to skilled nursing facility. Adjusted odds ratio for thirty-day mortality at the teaching hospital was 5.44 (95% CI = [1.22, 24.1]). Conclusion: We found longer operative times and elevated estimated blood loss with resident involvement in surgical fixation of hip fractures. There was a difference in 30-day mortality between the groups, although this cannot simply be attributed to resident involvement as there are many other factors related to mortality.
