PurposeAn association between hospital volume and postoperative mortality has been identified for several oncologic surgical procedures. Our objective was to analyze differences in surgical outcomes for patients with rectal cancer according to hospital volume in the state of California.MethodsA cross-sectional study from 2000 to 2005 was performed using the state of California Office of Statewide Health Planning and Development database. Hospitals were categorized into low (≤30)-, medium (31-60)-, and high (>60)-volume groups based on the total number of rectal cancer operations performed during the study period.ResultsOverall, 7,187 rectal cancer operations were performed. Of the 321 hospitals in the study cohort, 72 % (n = 232), 20 % (n = 65), and 8 % (n = 24) were low-, medium-, and high-volume hospitals, respectively. Postoperative mortality was significantly lower- in high-volume hospitals (0.9 %) when compared to medium- (1.1 %) and low-volume hospitals (2.1 %; p < 0.001). High-volume hospitals also performed more sphincter-preserving procedures (64 %) when compared to medium- (55 %) and low-volume hospitals (51 %; p < 0.001).ConclusionsThese data indicate that hospital volume correlates with improved outcomes in rectal cancer surgery. Rectal cancer patients may benefit from lower mortality and increased sphincter preservation in higher-volume centers.
