Chan et al developed the Cardiac Arrest Survival Postresuscitation In-Hospital (CASPRI) score for evaluating a patient who has had a cardiac arrest in the hospital. The authors are from multiple institutions in the United States participating in the Get With the Guidelines-Resuscitation Registry Investigators.
Patient selection: cardiac arrest in the hospital
Outcome: overall survival and neurological survival
Parameters:
(1) age in years
(2) initial arrest rhythm
(3) prearrest CRC (cerebral performance category) score from 0 to 5
(4) hospital location of arrest
(5) duration of resuscitation in minutes
(6) mechanical ventilation
(7) renal insufficiency
(8) hepatic insufficiency
(9) sepsis
(10) malignant disease
(11) hypotension

total score =
= SUM(points for all 11 parameters)
Interpretation:
• minimum score: 0
• maximum score: 50
• The higher the score the worse the survival.
