Cardiology Critical Care
CART Score for Cardiac Arrest Risk Triage
Cardiac Arrest Risk Triage (CART) score (Churpek 2012): ward respiratory rate, heart rate, diastolic BP and age predict ward cardiac arrest (AUC 0.84); it flagged arrests a median of 48 hours before the event.
Score interpretation
CART ≤ 20 0–20
Lower risk of ward cardiac arrest.
→ Routine observations per the early-warning system.
CART > 20 — Higher Risk 21–57
Higher risk of ward cardiac arrest (CART > 20: specificity 91.9 % in Churpek 2012).
→ Escalate for medical review per the local deterioration pathway.
Interpretation bands for the CART Score. Apply clinical judgement and local guidance.
