Outcomes of minimally invasive abdominal sacrocolpopexy with resident operative involvement.

INTRODUCTION AND HYPOTHESIS

Resident involvement in complex surgeries is under scrutiny with increasing attention paid to health care efficiency and quality. Outcomes of urogynecological surgery with resident involvement are poorly described. We hypothesized that resident surgical involvement does not influence perioperative outcomes in minimally invasive abdominal sacrocolpopexy (ASC).

METHODS

Using the 2006-2012 National Surgical Quality Improvement Program database, we identified 450 cases of laparoscopic or robotic ASC performed with resident involvement. Resident operative participation was stratified by experience (junior [PGY 1-3] vs senior level [PGY ≥4]). The primary outcome was operative time, and multinomial logistic regression was used to determine the effects of resident involvement and experience. Chi-squared analyses were used to assess the relationship between resident participation with length of stay (LOS) and 30-day complications and readmissions.

RESULTS

Residents participated in 74% (n = 334) of these surgeries, and these cases were significantly longer (median 220 vs 195 min, p = 0.03). On multivariate analysis, senior level resident involvement was associated with longer operative times across all time intervals compared with <2 h (2 to ≤4 h relative risk reduction [RRR] 4.1, p = 0.007, CI 1.47-11.40; 4 to ≤6 h RRR 6.6, p = 0.001, CI 2.23-19.44; ≥6 h RRR 4.7, p = 0.020, CI 1.28-17.43). Resident participation was not associated with LOS, readmissions, or complications.

CONCLUSIONS

Senior level resident involvement in minimally invasive ASC is associated with longer operative times, with no association with LOS or adverse perioperative outcomes. The educational benefit of surgical training does not adversely affect patient outcomes for ASC.
