BackgroundThree competing goals at academic medical centers are to increase efficiency, to optimize clinical care, and to train residents. The goal of this project was to compare day surgery operating room (OR) efficiency measures for anesthesiologists working alone, working with residents, and working with certified nurse anesthetists in a tertiary multisubspecialty teaching hospital to determine if trainees significantly impact OR efficiency.MethodsWe retrospectively evaluated operating room times data for 2,427 day surgery cases, comparing first case on-time starts, anesthesia-controlled times, induction times, emergence times, and turnover times for the 3 anesthesiologist groups.ResultsCompared to the solo anesthesiologist group, anesthesiologists working with residents had significantly longer induction, emergence, and total anesthesia-controlled times (20.2 ± 8.0 vs 18.4 ± 7.0 minutes). However, the anesthesiologists working with residents had more on-time starts (65% vs 53%) and lower turnover times 47.3 ± 13.6 vs 50.8 ± 14.5 minutes) than the solo anesthesiologist group.ConclusionThe pairing of anesthesiology residents with anesthesia staff has mixed effects on OR efficiency measures in a day surgery unit.
