The HOPE score provides a prediction of the survival probability in hypothermic cardiac arrest patients undergoing Extra-Corporeal Life Support (ECLS) rewarming. The score ranges from 0% to 100% chance of survival to hospital discharge.

A cutoff of 10% to decide which hypothermic patients in cardiac arrest would benefit or not from ECLS rewarming was evaluated in an external validation study. The negative predictive value of a HOPE score <10% was of 97%, and the AUC under the ROC curve was of 0.825 which suggest excellent discrimination.
