Churpek et al developed the cardiac arrest risk triage (CART) score to predict cardiac arrest in a patient in the hospital. The authors are from the University of Chicago.
Patient selection: adult in the hospital
Parameters:
(1) age in years
(2) maximum respiratory rate in breaths per minute
(3) maximum heart rate in beats per minute
(4) minimum diastolic blood pressure in mm Hg

total score =
= SUM(points for all 4 parameters)
Interpretation:
• minimum score: 0
• maximum score: 57
• The higher the score the greater the risk of a cardiac arrest.
Performance:
• The area under the ROC curve 0.84.
• A cutoff > 17 had a sensitivity of 53%.
• A cutoff > 20 had a sensitivity of 48% and specificity of 92%.
Purpose: To evaluate an adult inpatient using the cardiac arrest risk triage (CART) score of Churpek et al.
Objective: risk factors, severity, prognosis, stage
ICD-10: I46,
