Tonna et al reported the Rescue-IHCA Mortality Prediction Score for predicting outcome with extracorporeal cardiopulmonary resuscitation (ECPR). The authors are from the University of Utah, Boston Children's Hospital and Northwell Health.
Rescue-IHCA is derived from Resuscitation Using ECPR during in-hospital cardiac arrest
Parameters:
(1) age in years
(2) pre-existing renal insufficiency
(3) time of day
(4) illness category
(5) presenting rhythm
(6) duration of cardiac arrest in minutes

Interpretation:
• minimum score: -17 (approximately)
• maximum score: 43 (approximately); in Figure 3 it appears to be 48
