The ACTA-PORT score is a simple, preoperatively obtainable tool that may provide useful insight into CSA-AKI risk.
Study context
- Population
- Adults undergoing open-heart surgery with CPB, July–November 2024; pre-existing renal dysfunction excluded
- Participants
- 467 adults
- Outcome
- CSA-AKI (Kidney Disease: Improving Global Outcomes criteria)
Methodological detailssingle institution, tertiary care hospital
- Single institution
- Tertiary care hospital
Main finding
As reported in the abstract
CSA-AKI incidence and association with ACTA-PORT score
Odds ratio
1.07
95% CI 1.03–1.12
P = 0.002
Higher ACTA-PORT score
OR 1.07 (95% CI 1.03–1.12); P = 0.002
- Cardiac surgery-associated acute kidney injury (CSA-AKI) occurred
- 178 patients (38.1%)
Observational data: associations, not effects.
Further findings
Other predictors of CSA-AKI (multivariate analysis)
- Advanced age, prolonged cross-clamp time and emergency surgery independent predictors; statin use and preserved ejection fraction protective
Outcomes in patients with CSA-AKI
- Significantly higher rates of ICU complications, prolonged hospitalization and 30-day mortality
