PEDIATRIC RISK OF MORTALITY (PRISM) CALCULATOR


Physiologic variables are measured only in the first 4 hours of PICU care, and laboratory variables are measured in the time period from 2 hours before PICU admission through the first 4 hours. Neurologic score is calculated using GCS and Pupillary reflexes scores. Non-Neurologic is calculated from the remainder.
