Introduction: General surgery resident participation continues to be an important topic of conversation regarding resident education, particularly with the more restrictive 80 hour work week and emphasis on quality metrics guiding reimbursement. Previous literature has shown that resident participation does not negatively impact patient outcomes in low risk procedures. The aim of this study was to confirm that resident participation remains safe, as well as to explore changes in postoperative outcomes over time for high risk general surgery procedures (those where residents may get fewer opportunities to actively participate) cases performed with resident physicians.
Methods:
The National Surgical Quality Improvement Program database (2005-2012) was used to identify patients undergoing one of five high risk procedures: esophagectomy, open abdominal aortic aneurysm repair, laparoscopic paraesophageal hernia repair with Nissen fundoplication, pancreaticoduodenectomy, abdominoperineal resection, and hepatectomy. Outcomes were compared for patients with and without resident participation. Groups were created using a 2:1 propensity score match on the basis of age, sex, race, morbidity probability, ASA class, surgical specialty, comorbidities, and procedures. Postoperative outcomes were calculated using univariate statistics; chi square and ttest for categorical and continuous variables respectively. Trends in outcome over time were assessed using the Cochrane-Armitage test for trend. Predictors of mortality and overall complications were analyzed using decision tree analysis.
Results:
25,363 patients met our inclusion criteria. Following matching, the res and non-res groups had 500 patients each and were comparable for matched characteristics. 30 Day mortality was similar between the groups (2.4% v. 2.6% p=0.839). Deep surgical site infection (0% v. 1.6% p=0.005), urinary tract infection (5% v. 2.5% p=0.029), and operative time (275.6 min v.250 min p=0.0064) were all significantly higher in the resident participation group. Rates of other outcomes such as total length of stay, superficial surgical site infection, and sepsis were not significantly different. In examining trends over time, overall resident participation has decreased slightly from 2005 to 2012 (p=0.0061). 30 Day mortality has remained the same over time, while operative time, LOS, and returns to the OR have all decreased over time (all with p<0.001). Resident participation was not predictive of mortality or complications; while age, ASA class, and functional status were leading predictors of both.
Conclusion:
Despite growing time constraints and pressure to perform, surgical residents continue to perform at a high level and do not negatively affect postoperative outcomes. Residents should continue to be given active and engaging roles in the operating room, even in the most challenging cases.
