Background: The objective of the current national cohort study was to analyze the correlation between choice and competition on outcomes after cancer surgery in rectal cancer.
Methods: The analysis included all men who underwent rectal cancer surgery in the English National Health Service between March 2015 and April 2019 (n = 13,996). Multilevel logistic regression was used to assess the effect of a rectal cancer surgery center being located in a competitive environment (based on the number of centers within a threshold distance) and being a successful competitor (based on the ability to attract patients from other hospitals) on eight patient-level outcomes: 30- and 90-day emergency readmissions, 30-day re-operation rates, 90-day postoperative mortality, length of stay >14 days, circumferential resection margin status, rates of primary procedure with a permanent stoma, and rates of persistent stoma 18 months after anterior resection.
Results: With adjustment for patient characteristics, patients who underwent surgery in centers located in a stronger competitive environment were less likely to have an abdominoperineal excision or a Hartman's procedure (odds ratio [OR], 0.73; 95% confidence interval [CI], 0.55-0.97, p = .04). Additionally, individuals who received treatment at hospitals that were successful competitors had a lower risk of a 90-day readmission following rectal cancer surgery (OR, 0.86; 95% CI, 0.76-0.97, p = .03) and were less likely to have a persistent stoma at 18 months after anterior resection (OR, 0.75; 95% CI, 0.61-0.93, p = .02).
Conclusions: Hospitals located in areas of high competition are associated with better patient outcomes and improved processes of care for rectal cancer surgery.
