Reconceptualizing non-pharmacologic approaches to Neonatal Abstinence Syndrome (NAS) and Neonatal Opioid Withdrawal Syndrome (NOWS): A theoretical and evidence-based approach.

Discussions about non-pharmacologic interventions for Neonatal Abstinence Syndrome and Neonatal Opioid Withdrawal Syndrome (NAS/NOWS) have been minor compared with wider attention to pharmacologic treatments. Although historically under-recognized, non-pharmacologic interventions are of paramount importance for all substance-exposed infants and remain as a first line therapy for the care of infants affected by NAS. Here we examine the role of non-pharmacologic interventions for NAS/NOWS by incorporating theoretical perspectives from different disciplines that inform the importance of individualized assessment of the mother-caregiver/infant dyad and interventions that involve both individuals. NAS/NOWS is a complex, highly individualized constellation of signs/symptoms that vary widely in onset, duration, severity, expression, responses to treatment and influence on long-term outcomes. NAS/NOWS often occurs in infants with multiple prenatal/postnatal factors that can compromise neurobiological self-regulatory functioning. We propose to rethink some of the long-held assumptions, beliefs, and paradigms about non-pharmacologic care of the infant with NAS/NOWS, which is provided as non-specific or as "bundled" in current approaches. This paper is Part I of a two-part series on re-conceptualizing non-pharmacologic care for NAS/NOWS as individualized treatment of the dyad. Here, we set the foundation for a new treatment approach grounded in developmental theory and evidence-based observations of infant neurobiology and neurodevelopment. In Part II, we provide actionable, individually tailored evaluations and approaches to non-pharmacologic NAS/NOWS treatment based on measurable domains of infant neurobehavioral functioning.
