Cardiac Anesthesia Risk Evaluation Score (CARE)

Simple clinical-judgement classification of risk before cardiac surgery.

Cardiac Anesthesia Risk Evaluation Score (CARE)
Clinical class
Emergency surgery (cannot be delayed for full workup/optimisation)
ResultClass 1

Risk of mortality and major morbidity rises progressively from class 1 to 5.

When to use

  • Rapid bedside risk stratification before cardiac surgery, as an alternative to multifactorial indices (e.g., EuroSCORE).

Formula

Clinical-judgement classification into 5 classes based on comorbidity control and surgical complexity, with an 'E' modifier appended for emergency surgery.

Pearls and pitfalls

  • Performs comparably to more complex multifactorial risk indices (Parsonnet, Tuman, Tu) for predicting mortality and morbidity after cardiac surgery.
  • Relies on clinician judgement rather than a fixed checklist, so inter-rater calibration matters.
