Postnatal SNAP-II scores in neonatal intensive care unit patients: Relationship to sepsis, necrotizing enterocolitis, and death

Objective. To determine if daily SNAP-II scores (Score for Neonatal Acute Physiology) after the first day are useful in identifying neonatal intensive care unit (NICU) patients who die or develop sepsis or necrotizing enterocolitis. Study design. Prospective data were collected on all 141 admissions to a university level III NICU over 4 months. SNAPPE-II scores were calculated from the day of admission and SNAP-II scores from subsequent hospital days. The scores were compared between those who developed events and those who did not. Results. At least 64% of the daily SNAP-II scores on the day of and the preceding 4 days from the event were 0. Admission SNAPPE-II scores correlated with length of stay (r = 0.44, p < 0.01) but patient average SNAP-II did not (r = 0.02, p > 0.5). Conclusions. SNAP-II scores from after the first day of life did not accurately assess or predict neonatal morbidity and mortality.
