Abstract
BACKGROUND: The aim of this study was to evaluate the impact of Surgical Unit volume on the 30-day reoperation rate in patients with CRC. METHODS: Data were extracted from the regional Hospital Discharge Dataset and included patients who underwent elective resection for primary CRC in the Veneto Region (2005-2013). The primary outcome measure was any unplanned reoperation performed within 30 days from the index surgery. Independent variables were: age, gender, comorbidity, previous abdominal surgery, site and year of the resection, open/laparoscopic approach and yearly Surgical Unit volume for colorectal resections as a whole, and in detail for colonic, rectal and laparoscopic resections. Multilevel multivariate regression analysis was used to evaluate the impact of variables on the outcome measure. RESULTS: During the study period, 21,797 elective primary colorectal resections were performed. The 30-day reoperation rate was 5.5% and was not associated with Surgical Unit volume. In multivariate multilevel analysis, a statistically significant association was found between 30-day reoperation rate and rectal resection volume (intermediate-volume group OR 0.75; 95% CI 0.56-0.99) and laparoscopic approach (high-volume group OR 0.69; 95% CI 0.51-0.96). CONCLUSIONS: While Surgical Unit volume is not a predictor of 30-day reoperation after CRC resection, it is associated with an early return to the operating room for patients operated on for rectal cancer or with a laparoscopic approach. These findings suggest that quality improvement programmes or centralization of surgery may only be required for subgroups of CRC patients.
