Discharge to Nonhome Locations and Association With Long-term Survival After Cardiac Surgery in Australia and New Zealand Intensive Care Units: A Retrospective Multicenter Cohort Study
Main finding · Survival (Cox proportional hazards)Result — go to the resultHR for death 1.91 95% CI 1.75–2.09Authors' conclusion
NHD after cardiac surgery is associated independently with decreased long-term survival, with the highest risk observed within the first year.

- Exposure
- Nonhome discharge vs home discharge
- Nonhome discharge (NHD)n = 13,444
- Outcome

Survival by NHD location
- No significant differences between NHD locations
Survival by surgery type and emergency status (subgroup)
- Lower survival after NHD vs home discharge (HD) across all surgery types, emergency and elective
