The CAHP (Cardiac Arrest Hospital Prognosis) score: a tool for risk stratification after out-of-hospital cardiac arrest
Authors' conclusion
The CAHP score represents a simple tool for early stratification of patients admitted in ICU after OHCA. A high-risk category of patients with very poor prognosis can be easily identified.
