BACKGROUND: With increasing scrutiny being placed on the allocation of health care dollars, data supporting the increased resources used to teach residents in the operating room (OR) are lacking. METHODS: All cases of patients undergoing laparoscopic cholecystectomies (LCs) and pancreaticoduodenectomies (PDs) from July 1, 2006 to July 1, 2011 were analyzed. Procedures were excluded based on the following: more than one resident listed in the operative report, with the exception of interns; LC requiring cholangiogram or conversion to an open procedure; or if a PD required additional procedures. Multiple linear regression was used to evaluate the association between procedure time and postgraduate year (PGY), adjusting for patient age and estimated blood loss. RESULTS: A total of 236 PDs and 357 LCs were included in the study. For LCs, after multiple linear regression, the association between procedure time and resident PGY was marginally significant (P = 0.0519) and suggested an inverse relationship; for every increase in resident PGY, there was a 2.66-min decrease in OR time. Based on our institution's figure of $18.13/min of OR time, the cost difference between PGYs 1 and 5 performing a LC would be $192.90 per case. For PDs, however, the association between procedure time and resident PGY was not significant. CONCLUSIONS: Junior residents likely prolong procedure times for more basic procedures such as LC but not for more complex procedures such as PD.
