Background The role of service centralization in rectal cancer surgery is controversial. Recent studies suggest centralization to high‐volume centres may improve postoperative mortality. We used a state‐wide administrative data set to determine the inpatient mortality for patients undergoing elective rectal cancer surgery and to compare individual hospital volumes. Methods The Victorian Admitted Episodes Dataset was explored using the Dr Foster Quality Investigator tool. The inpatient mortality rate, 30‐day readmission rate and the proportion of patients with increased length of stay were measured for all elective admissions for rectal cancer resections between 2012 and 2016. A peer group of 14 hospitals were studied using funnel plots to determine inter‐hospital variation in mortality. Procedure types were compared between the groups. Results There were 2241 elective resections performed for rectal cancer in Victoria over 4 years. The crude inpatient mortality rate was 1.1%. There were no significant differences in mortality among 14 hospitals within the peer group. The number of elective resections over 4 years ranged from 14 to 136 (median 65) within these institutions. Ultralow anterior resection was the commonest procedure performed. Conclusion Inpatient mortality after elective rectal cancer surgery in Victoria is rare and compares favourably internationally. Based on inpatient mortality alone, there is no compelling evidence to further centralize elective rectal cancer surgery in Victoria. More work is needed to develop data sets with oncological information capable of providing accurate complete state‐wide data which will be essential for future service planning, training and innovation.
