The problems of moderate preterm infants.

Moderate preterm infants are the largest group of preterm infants but are an understudied population. Care practices are adapted from studies of full term infants or extremely preterm infants. Studies are needed to tailor treatments for this vulnerable population. The NRN began investigation in this population with a registry of characteristics, and neonatal outcomes of these infants. This work compares outcomes of MPR with those of full term infants reported in the literature.
