ICU sedation, delirium & recovery
Evaluation of days alive out of hospital as an outcome after intensive care admission: a national retrospective cohort study
Authors' conclusion
Our study provides evidence to support the use of DAOH for patients admitted to ICU, however DAOH30 is unlikely to be a suitable measure.
Study context

- Participants

- Outcome
- Relationship between DAOH and prognostic indicators; performance of DAOH30, DAOH90 and DAOH180
