Acute cardiac care & resuscitation
Presentation and Outcomes of Patients With Preoperative Critical Illness Undergoing Cardiac Surgery
Authors' conclusion
Nearly 1 in 12 contemporary CICU patients receive cardiac surgery. Despite high preoperative disease severity, CICU admissions undergoing cardiac surgery had a comparable mortality rate to CICU patients overall
Study context
- Population
- Cardiac ICU admissions referred for cardiac surgery, 2017 to 2020, 29 centres
- Participants
- 887 vs 10,321
- Exposure
- Cardiac surgery vs all cardiac intensive care unit (CICU) admissions
- Cardiac surgeryn = 887
- All CICU admissionsn = 10,321reference
- Outcome
- In-hospital mortality
