ICU sedation, delirium & recovery
Accuracy between intensive care unit (ICU) admission and discharge diagnoses in non-survivors: A retrospective cohort study
Authors' conclusion
Differences between ICU admission and discharge diagnoses occur frequently, this leads to only a small discrepancy in the overall predicted mortality of deceased ICU patients.
Study context
- Population
- Deceased patients admitted to the ICU between Jan 1, 2018 and Dec 31, 2020deceased of 5633 ICU patients
- Participants
- 886 patients
- Exposure
- Acute Physiologic and Chronic Health Evaluation (APACHE) IV predicted mortality using admission vs discharge diagnoses
- Outcome
- Agreement between APACHE IV predicted mortality using admission vs discharge diagnoses (mean difference and ICC)
