Abstract
Background
General surgery residents are increasingly pursuing sub-specialty training in colorectal (CR) surgery. However, the majority of operations performed by CR surgeons are also performed by general surgeons. This study aimed to assess in-hospital mortality stratified by CR training status after adjusting for surgeon and hospital volume.
Methods
The Statewide Planning and Research Cooperative system database was used to identify all patients who underwent colectomy/proctectomy from January 1, 2000, to December 31, 2014, in the state of New York. Operations performed by board-certified CR surgeons were identified. The relationships between CR board certification and in-hospital mortality, in-hospital complications, length of stay, and ostomy were assessed using multivariate regression models.
Results
Two hundred seventy thousand six hundred eighty-four patients underwent colectomy/proctectomy over the study period. Seventy-two thousand two hundred seventy-nine (26.7%) of operations were performed by CR surgeons. Without adjusting for hospital and surgeon volume, in-hospital mortality was lower for those undergoing colectomy/proctectomy by a CR surgeon (OR 0.49, CI 0.44–0.54, p = 0.001). After controlling for hospital and surgeon volume, the odds of inpatient mortality after colectomy/proctectomy for those operated on by CR surgeons weakened to 0.76 (CI 0.68–0.86, p = 0.001). Hospital and surgeon volume accounted for 53% of the reduction in in-hospital mortality when CR surgeons performed colectomy/proctectomy. Patients who underwent surgery by a CR surgeon had a shorter inpatient stay (0.8 days, p = 0.001) and a decreased chance of colostomy (OR 0.86, CI 0.78–0.95, p < 0.001).
Conclusions
For patients undergoing colectomy/proctectomy, in-hospital mortality decreased when the operation was performed by a CR surgeon even after accounting for hospital and surgeon volume.
