There is increasing recognition that parents play a critical role in promoting the health outcomes of low birthweight and preterm infants. Despite a large body of literature on interventions and models to support family engagement in infant care, parent involvement in the delivery of care for such infants is still restricted in many neonatal intensive care units (NICUs). This article proposes a taxonomy for classifying parent-focused NICU interventions and parent-partnered care models to aid researchers, clinical teams, and health systems to evaluate existing and future approaches to care. The proposed framework has three levels: interventions to support parents, parent-delivered interventions, and multidimensional models of NICU care that explicitly incorporate parents and partners in the care of their preterm or low birthweight infant.
