Effect of Resident and Fellow Involvement on Outcomes of Sarcoma Surgery: A NSQIP Database Cross-Sectional Study

Table 4

Univariable and multivariable fractional logistic regression analyses of trainee participation and complication severity.

	Univariable beta (95% CI)	value	Multivariable beta (95% CI)	value
Trainee presence	0.711 (−0.481–1.902)	0.243	0.488 (−0.685–1.661)	0.415
Age	—	—	0.002 (−0.015–0.020)	0.791
Hematologic comorbidity	—	—	−0.141 (−1.024–0.741)	0.754
Pre-op chemotherapy/radiation	—	—	0.210 (−0.448–0.868)	0.532
ASA class	—	—	−0.237 (−0.640–0.165)	0.248
Total wRVUs	—	—	0.011 (0.006–0.017)	<0.001
Lower extremity surgery	—	—	0.492 (−0.571–1.555)	0.365

There was no significant association between of resident presence and severity of complications found, as measured by the SWORD score (the severity weighting of postoperative adverse events in orthopedic surgery). CI = confidence interval, ASA = American Society of Anesthesiologists, and wRVUs = work relative value units. .
