Abstract

Object: This study evaluates the impact of resident presence in the operating room on postoperative outcomes in neurosurgery.

Methods: The authors retrospectively reviewed the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) and identified all cases treated in a neurosurgery service in 2011. Propensity scoring analysis and multiple logistic regression models were used to reduce patient bias and to assess independent effect of resident involvement.

Results: Of the 8748 neurosurgery cases identified, residents were present in 4529 cases. Residents were more likely to be involved in complex procedures with longer operative duration. The multivariate analysis found that resident involvement was not a statistically significant factor for overall complications (OR 1.116, 95% CI 0.961-1.297), surgical complications (OR 1.132, 95% CI 0.825-1.554), medical complications (OR 1.146, 95% CI 0.979-1.343), reoperation (OR 1.250, 95% CI 0.984-1.589), mortality (OR 1.164, 95% CI 0.780-1.737), or unplanned readmission (OR 1.148, 95% CI 0.946-1.393).

Conclusions: In this multicenter study, the authors demonstrated that resident involvement in the operating room was not a significant factor for postoperative complications in neurosurgery service. This analysis also showed that much of the observed difference in postoperative complication rates was attributable to other confounding factors. This is a quality indicator for resident trainees and current medical education. Maintaining high standards in postgraduate training is imperative in enhancing patient care and reducing postoperative complications.
