Acute cardiac care & resuscitationCohort study
Systematic Assessment of Shock Severity in Postoperative Cardiac Surgery Patients
- Retrospective cohort study
- single-centre
Authors' conclusion
The SCAI shock classification effectively risk-stratifies postoperative CSICU patients for mortality, postoperative complications, and organ dysfunction.
Study context
- Population
- Postoperative cardiac surgery ICU (cardiac surgery intensive care unit (CSICU)) admissions at a heart center, 2012–2022
- Participants
- 26,792 CSICU admissions
- Exposure
- SCAI shock stages A to E
- Outcome
- Hospital mortality
Main finding
Hospital mortality (crude)
Adjusted odds ratio
1.26-16.59
By group
As reported in the abstract
- SCAI shock classification AUC for hospital mortality
- 0.84
- SCAI shock classification + late deterioration AUC for hospital mortality
- 0.90
Observational data: associations, not effects.
Further findings
| Outcome | adjusted OR |
|---|---|
| Late deterioration (LD) and hospital mortality | 8.2 |
Postoperative complications and organ dysfunction
- Prevalence increased across SCAI shock stages
