The objective of this study is to investigate the relationship between resident involvement in the operating room and 30-day complication rates in patients undergoing lumbar spinal fusion procedures. We used the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database to retrospectively identify all patients who underwent a lumbar spinal fusion from 2006 to 2013. A propensity score matching algorithm was employed to minimize baseline differences. Multivariate logistic regression analysis of unadjusted and propensity-matched groups was performed to examine the effect of resident participation on operative details and 30-day complication rates. A total of 5655 patients met the inclusion criteria and propensity score matching yielded 1965 well-matched pairs. Resident involvement in lumbar fusion procedures was not found to be a significant predictor for mortality or reoperation. It was found to be a significant predictor for increased hospital stay (matched non-resident 4.0?±?5.8?days vs. resident 4.6?±?4.3?days, p?<?0.001), operative time (matched non-resident 198?±?102?min vs. resident 243?±?118?min, p?<?0.001), sepsis (matched OR 4.36, 95% CI 2.10–9.05, p?<?0.001), development of DVT/PE (matched OR 2.02, 95% CI 1.10–3.70, p?=?0.023), and superficial surgical site infections (matched OR 1.78, 95% CI 1.04–3.06, p?=?0.037). In conclusion, this large-scale, population-based study found that resident participation in the operating room was safe but increased the risk of 30-day complications and increased operative duration and length of hospital stay. 收起
