A propensity score matching analysis: Impact of senior resident versus fellow participation on outcomes of complex surgical oncology

Background: Teaching hospitals that train both general surgery residents and fellows in complex general surgical oncology have become more common. This study investigates whether participation of a senior resident versus a fellow has an impact on outcomes of patients undergoing complex cancer surgery.Methods: Patients who underwent esophagectomy, gastrectomy, hepatectomy, or pancreatectomy between 2007 and 2012 with assistance from a senior resident (post-graduate years 4–5) or a fellow (post-graduate years 6–8) were identified from the ACS NSQIP. Based on age, sex, body mass index, ASA classification, diagnosis of diabetes mellitus, and smoking status, propensity-scores were created for odds of undergoing the operation assisted by a fellow. Patients were matched 1:1 based on propensity score. Postoperative outcomes including risk of major complication were compared after matching.Results: In total, 6934 esophagectomies, 13,152 gastrectomies, 4927 hepatectomies, and 8040 pancreatectomies were performed with assistance of a senior resident or fellow. After matching, overall rates of major complications were equivalent across all four anatomic locations between cases performed with the participation of a senior resident versus a surgical fellow: esophagectomy (37.0%% vs 31.6%, p = 0.10), gastrectomy (22.6% vs 22.3%, p = 0.93), hepatectomy (15.8% v 16.0%, p = 0.91), and pancreatectomy (23.9% vs 25.2%, p = 0.48). Operative time was shorter for gastrectomy (212 vs. 232 min; p = 0.004) involving a resident compared to a fellow, but comparable for esophagectomy (330 vs. 336 min; p = 0.41), hepatectomy (217 vs. 219 min; p = 0.85), and pancreatectomy (320 vs. 330 min; p = 0.43).Conclusions: Senior resident participation in complex cancer operations does not appear to negatively impact operative time or postoperative outcomes. Future research is needed to further assess this domain of surgical practice and education, particularly with regard to case selection and operative complexity. Ausführliche Beschreibung

This study investigates whether participation of a senior resident versus a fellow has an impact on outcomes of patients undergoing complex cancer surgery.Methods: Patients who underwent esophagectomy, gastrectomy, hepatectomy, or pancreatectomy between 2007 and 2012 with assistance from a senior resident (post-graduate years 4–5) or a fellow (post-graduate years 6–8) were identified from the ACS NSQIP. Based on age, sex, body mass index, ASA classification, diagnosis of diabetes mellitus, and smoking status, propensity-scores were created for odds of undergoing the operation assisted by a fellow. Patients were matched 1:1 based on propensity score. Postoperative outcomes including risk of major complication were compared after matching.Results: In total, 6934 esophagectomies, 13,152 gastrectomies, 4927 hepatectomies, and 8040 pancreatectomies were performed with assistance of a senior resident or fellow. After matching, overall rates of major complications were equivalent across all four anatomic locations between cases performed with the participation of a senior resident versus a surgical fellow: esophagectomy (37.0%% vs 31.6%, p = 0.10), gastrectomy (22.6% vs 22.3%, p = 0.93), hepatectomy (15.8% v 16.0%, p = 0.91), and pancreatectomy (23.9% vs 25.2%, p = 0.48). Operative time was shorter for gastrectomy (212 vs. 232 min; p = 0.004) involving a resident compared to a fellow, but comparable for esophagectomy (330 vs. 336 min; p = 0.41), hepatectomy (217 vs. 219 min; p = 0.85), and pancreatectomy (320 vs. 330 min; p = 0.43).Conclusions: Senior resident participation in complex cancer operations does not appear to negatively impact operative time or postoperative outcomes. Future research is needed to further assess this domain of surgical practice and education, particularly with regard to case selection and operative complexity.

Patients were matched 1:1 based on propensity score. Postoperative outcomes including risk of major complication were compared after matching.Results: In total, 6934 esophagectomies, 13,152 gastrectomies, 4927 hepatectomies, and 8040 pancreatectomies were performed with assistance of a senior resident or fellow. After matching, overall rates of major complications were equivalent across all four anatomic locations between cases performed with the participation of a senior resident versus a surgical fellow: esophagectomy (37.0%% vs 31.6%, p = 0.10), gastrectomy (22.6% vs 22.3%, p = 0.93), hepatectomy (15.8% v 16.0%, p = 0.91), and pancreatectomy (23.9% vs 25.2%, p = 0.48). Operative time was shorter for gastrectomy (212 vs. 232 min; p = 0.004) involving a resident compared to a fellow, but comparable for esophagectomy (330 vs. 336 min; p = 0.41), hepatectomy (217 vs. 219 min; p = 0.85), and pancreatectomy (320 vs. 330 min; p = 0.43).Conclusions: Senior resident participation in complex cancer operations does not appear to negatively impact operative time or postoperative outcomes. Future research is needed to further assess this domain of surgical practice and education, particularly with regard to case selection and operative complexity.</subfield></datafield><datafield

title_auth	A propensity score matching analysis: Impact of senior resident versus fellow participation on outcomes of complex surgical oncology
abstract	Background: Teaching hospitals that train both general surgery residents and fellows in complex general surgical oncology have become more common. This study investigates whether participation of a senior resident versus a fellow has an impact on outcomes of patients undergoing complex cancer surgery.Methods: Patients who underwent esophagectomy, gastrectomy, hepatectomy, or pancreatectomy between 2007 and 2012 with assistance from a senior resident (post-graduate years 4–5) or a fellow (post-graduate years 6–8) were identified from the ACS NSQIP. Based on age, sex, body mass index, ASA classification, diagnosis of diabetes mellitus, and smoking status, propensity-scores were created for odds of undergoing the operation assisted by a fellow. Patients were matched 1:1 based on propensity score. Postoperative outcomes including risk of major complication were compared after matching.Results: In total, 6934 esophagectomies, 13,152 gastrectomies, 4927 hepatectomies, and 8040 pancreatectomies were performed with assistance of a senior resident or fellow. After matching, overall rates of major complications were equivalent across all four anatomic locations between cases performed with the participation of a senior resident versus a surgical fellow: esophagectomy (37.0%% vs 31.6%, p = 0.10), gastrectomy (22.6% vs 22.3%, p = 0.93), hepatectomy (15.8% v 16.0%, p = 0.91), and pancreatectomy (23.9% vs 25.2%, p = 0.48). Operative time was shorter for gastrectomy (212 vs. 232 min; p = 0.004) involving a resident compared to a fellow, but comparable for esophagectomy (330 vs. 336 min; p = 0.41), hepatectomy (217 vs. 219 min; p = 0.85), and pancreatectomy (320 vs. 330 min; p = 0.43).Conclusions: Senior resident participation in complex cancer operations does not appear to negatively impact operative time or postoperative outcomes. Future research is needed to further assess this domain of surgical practice and education, particularly with regard to case selection and operative complexity.

This study investigates whether participation of a senior resident versus a fellow has an impact on outcomes of patients undergoing complex cancer surgery.Methods: Patients who underwent esophagectomy, gastrectomy, hepatectomy, or pancreatectomy between 2007 and 2012 with assistance from a senior resident (post-graduate years 4–5) or a fellow (post-graduate years 6–8) were identified from the ACS NSQIP. Based on age, sex, body mass index, ASA classification, diagnosis of diabetes mellitus, and smoking status, propensity-scores were created for odds of undergoing the operation assisted by a fellow. Patients were matched 1:1 based on propensity score. Postoperative outcomes including risk of major complication were compared after matching.Results: In total, 6934 esophagectomies, 13,152 gastrectomies, 4927 hepatectomies, and 8040 pancreatectomies were performed with assistance of a senior resident or fellow. After matching, overall rates of major complications were equivalent across all four anatomic locations between cases performed with the participation of a senior resident versus a surgical fellow: esophagectomy (37.0%% vs 31.6%, p = 0.10), gastrectomy (22.6% vs 22.3%, p = 0.93), hepatectomy (15.8% v 16.0%, p = 0.91), and pancreatectomy (23.9% vs 25.2%, p = 0.48). Operative time was shorter for gastrectomy (212 vs. 232 min; p = 0.004) involving a resident compared to a fellow, but comparable for esophagectomy (330 vs. 336 min; p = 0.41), hepatectomy (217 vs. 219 min; p = 0.85), and pancreatectomy (320 vs. 330 min; p = 0.43).Conclusions: Senior resident participation in complex cancer operations does not appear to negatively impact operative time or postoperative outcomes.
