Abstract only Background: The cardiac arrest hospital prognosis (CAHP) score has been shown in French studies to predict neurologic outcomes in patients who suffer an out-of-hospital cardiac arrest (OHCA), but this score has not been studied in an American cohort. We aimed to validate the CAHP score in an independent, single center, large cardiac arrest registry. Methods: Between January 2015 to June 2020 there were 925 patients who suffered OHCA and were transferred to Northeast Georgia Medical Center out of whom 450 patients survived to hospital admission. Cerebral Performance Category (CPC) score was used for assessment of neurologic outcome at discharge ranging from 1-5. The primary endpoint was poor neurologic outcome defined as CPC 3-5. Logistic regression was performed to identify independent predictors of poor neurologic outcome. Results: Included patients were mostly male 57% (256 of 450) with a mean age of 52±15. STEMI was present on 11% (51 of 450) and a shockable rhythm on 35% (150 of 450) of patients. Targeted temperature management (TTM) and a mechanical compression device (MCD) were used in 72% (327 of 450) and 74% (336 of 450) respectively. 76% (344 of 450) had a CPC of 3-5 at discharge. After adjusting for covariates, including gender, BMI, serum lactate level, witnessed arrest status, STEMI on ECG, and use of MCD and TTM, the only independent predictors of a CPC of 3-5 were CAHP score (p200 were associated with a 12-fold (p
