Objective: There is no validated tool to assess iatrogenic opioid withdrawal in preterm infants in the newborn intensive care unit (NICU).
Study design: The Neonatal Withdrawal Assessment Tool (NWAT) was developed to address this gap in clinical practice. In this pilot study, the NWAT was assessed for inter-rater reliability (IRR) and content validity.
Result: Fifty-one NICU providers scored two standardized simulated cases, then 20 paired provider assessments were completed on 5 preterm infants. The overall IRR was 95.6% on the simulated cases, and 98.8% on the 5 pilot infants. A provider survey assessed for content validity; all of the provider participants strongly agreed/agreed that the NWAT adequately measures withdrawal in critically ill infants.
Conclusion: The NWAT demonstrated high IRR and content validity for assessment of iatrogenic opioid withdrawal in preterm infants in this pilot study. Further studies in a larger more diverse patient population are needed before wider adoption into clinical practice.
