A New Scoring System for the Assessment of Neonatal Abstinence Syndrome.

Objective: This study aimed to evaluate the concordance of a new scoring system for neonatal abstinence syndrome (NAS) and NAS scores to the traditional Modified Finnegan Neonatal Abstinence Scoring Tool (M-FNAST) score. The NAS score is based on the physiology of withdrawal, with equal emphasis on behavior, and neurological signs.

Study Design: The NAS scores for a control group of 202 healthy, term neonates were compared with those for 45 term neonates with NAS.
