Why the study?
To develop a postoperative mortality case-mix adjustment model to assess cardiac ICU quality of care and describe variation in adjusted mortality across hospitals.
A novel case-mix adjustment model reveals significant variation in risk-adjusted postoperative mortality across pediatric cardiac ICUs, highlighting opportunities for quality improvement.
Risk-adjusted model supports pediatric cardiac ICU benchmarking; leaves open whether variation reflects quality or unmeasured factors.
