Hospital variation in ‘days alive and out of hospital’ after colorectal cancer surgery: a national retrospective cohort study
Authors' conclusion
Hospital variation in DAOH90 among patients with complications reflects differences in capacity to rescue.

- Outcome
- Hospital-level variation in risk-adjusted days alive and out of hospital (DAOH) within 90 days of surgery (DAOH90), stratified by complications
- Follow-up
- 90 days
