Purpose: To assess whether resident involvement (RI) in immediate breast reconstruction (IBR) is associated with increased 30-day surgical morbidity.
Methods: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was used to identify patients undergoing IBR between 2005 and 2012. Preoperative demographics, intraoperative variables, RI in surgery, and 30-day postoperative surgical morbidities were identified. Chi-squared test and multivariable logistic regression were used to estimate the effect of RI on surgical complications.
Results: 24,005 patients underwent IBR (17,840 with RI). Thirty-day surgical morbidity was observed in 5.25% (95% CI:4.92%-5.58%) of cases with RI and 5.12% (95% CI:4.59%-5.58%) of cases without RI. Odds of surgical complications were not statistically different between groups (unadjusted OR:1.03; 95% CI: 0.90-1.17, p=0.690) even after controlling for confounding with multivariable logistic regression (adjusted OR:0.97; 95% CI:0.85-1.11; p=0.652). Subgroup analysis by type of reconstruction showed that RI was not associated with surgical complications in implant-based reconstructions, but was associated with lower odds of surgical complications in autologous reconstructions (OR:0.70; 95% CI: 0.53-0.91; p=0.008). However, operative time and reoperation rates were significantly higher with RI across all types of reconstruction (both p<0.001). Postoperative length of stay was statistically significantly longer with RI in autologous reconstruction (mean=3.94, SD=2.42, versus mean=3.73, SD=1.78, respectively; p=0.015) but not in implant reconstruction (p=0.765).
Conclusion: Although this study found no statistically significant evidence for increased post-operative surgical morbidity in IBR patients for whom residents were involved, RI statistically significantly increased operative time, post-operative length of stay, and reoperation rates.
