Effect of Model of Neonatal Care on Neurodevelopment at the 18 Month Follow-Up in Moderate and Late Preterm Infants.

Preterm birth, even for moderate or late preterm infants (MLPIs), is associated with longer-term developmental challenges. Family Integrated Care (FICare) models of care, like Alberta FICare, aim to improve outcomes by integrating parents into neonatal care during hospitalization. This follow-up study examined the association between models of care (Alberta FICare versus standard care) and risk of child developmental delay at 18 months corrected age (CA) and explored the influences of maternal psychosocial distress. We assessed 257 mothers and 298 infants from a cluster randomized controlled trial (ID: NCT0279799) conducted in ten Level II NICUs in Alberta, Canada. Risk of delay was assessed using developmental screening tests. Maternal psychosocial distress was assessed using self-reported measures of depressive symptoms, anxiety, parenting stress, and self-efficacy. There was no association between model of care and risk of developmental delay. Higher maternal parenting stress was associated with increased risk of developmental delay. Alberta FICare was not associated with decreased risk of developmental delay at 18 months CA. Maternal parenting stress may play an important role in the development of MLPIs and should be addressed post-discharge.
