BackgroundSurgical procedures have a learning curve regarding the number of cases required for proficiency. Consequently, involvement of less experienced resident surgeons may impact patients and the healthcare system. This study examines basic and advanced laparoscopic procedures performed between 2010 and 2011 and evaluates the resident surgeon participation effect.MethodsBasic laparoscopic procedures (BL), appendectomy (LA), cholecystectomy (LC), and advanced Nissen fundoplication (LN) were queried from the American College of Surgeons National Surgical Quality Improvement Program database. Cases were identified using Current Procedural Terminology codes. Analyses were performed using IBM SPSS Statistics v.22, α-level = 0.05. Multiple logistic regression was used, accounting for age, race, gender, admission status, wound classification, and ASA classification.ResultsIn total, 71,819 surgeries were reviewed, 66,327 BL (37,636 LC and 28,691 LA) and 5492 LN. Median age was 48 years for LC and 37 years for LA. In sum, 72.2 % of LC and 49.5 % of LA patients were female. LN median age was 59 years, and 67.7 % of patients were female. For BL, resident involvement was not significantly associated with mortality, morbidity, and return to the OR. Readmission was not related to resident involvement in LC. In LA, resident-involved surgeries had increased readmission and longer OR time, but decreased LOS. In LC, resident involvement was associated with longer LOS and OR time. Resident involvement was not a significant factor in the odds of mortality, morbidity, return to OR, or readmission in LN. Surgeries involving residents had increased odds of having longer LOS, and of lengthier surgery time.ConclusionsWe demonstrate resident involvement is safe and does not result in poorer patient outcomes. Readmissions and LOS were higher in BL, and operative times were longer in all surgeries. Resident operations do appear to have real consequences for patients and may impact the healthcare system financially.
