AKI O/E

Ratio of observed AKI events to expected AKI events based on patient characteristics and risk models.

Quality Improvement Strategies:

  • Standardize pre-procedural hydration to optimize renal perfusion.

  • Limit contrast volume, especially in high-risk patients, using eGFR-based thresholds.

  • Incorporate AKI risk screening for all PCI patients pre-procedure.

  • Embed AKI risk calculators in the EMR to guide clinical decision-making.

  • Audit AKI cases regularly to identify modifiable risk factors and procedural trends.

  • Review and implement VCSQI AKI Prevention Recommendations across care teams.

  • Provide ongoing training for interventional staff on evidence-based AKI mitigation practices.
