Impact of hospital volume on failure to rescue for complications requiring reoperation after elective colorectal surgery: multicentre propensity score-matched cohort study

Abstract

Background: It has previously been reported that there are similar reoperation rates after elective colorectal surgery but higher failure-to-rescue (FTR) rates in low-volume hospitals (LVHs) versus high-volume hospitals (HVHs). This study assessed the effect of hospital volume on reoperation rate and FTR after reoperation following elective colorectal surgery in a matched cohort. Methods: Population-based retrospective multicentre cohort study of adult patients undergoing reoperation for a complication after an elective, non-centralized colorectal operation between 2006 and 2017 in 11 hospitals. Hospitals were divided into either HVHs (3 hospitals, median ≥126 resections per year) or LVHs (8 hospitals, <126 resections per year). Patients were propensity score- matched (PSM) for baseline characteristics as well as indication and type of elective surgery. Primary outcome was FTR. Results: A total of 6428 and 3020 elective colorectal resections were carried out in HVHs and LVHs, of which 217 (3.4%) and 165 (5.5%) underwent reoperation (P < 0.001), respectively. After PSM, 142 patients undergoing reoperation remained in both HVH and LVH groups for final analyses. FTR rate was 7.7% in HVHs and 10.6% in LVHs (P = 0.410). The median Comprehensive Complication Index was 21.8 in HVHs and 29.6 in LVHs (P = 0.045). There was no difference in median ICU-free days, length of stay, the risk for permanent ostomy or overall survival between the groups. Conclusion: The reoperation rate and postoperative complication burden was higher in LVHs with no significant difference in FTR compared with HVHs.
