SNAPPE-II

The SNAP-II (Score for Neonatal Acute Physiology II) and SNAPPE-II (Score for Neonatal Acute Physiology with Perinatal Extension II) are severity-of-illness scoring systems designed for neonates in neonatal intensive care units (NICUs). Developed in 2001 as simplified updates to the original SNAP scores, they quantify illness severity and predict mortality risk in newborns, particularly preterm or critically ill infants. SNAP-II focuses on physiological parameters, while SNAPPE-II extends SNAP-II by incorporating perinatal factors. These scores are widely used for risk adjustment, outcome prediction, and quality assessment in NICUs.
