Effect of pre- and postdischarge interventions on breastfeeding outcomes and weight gain among premature infants.

摘要

OBJECTIVE: To investigate the effect of pre- and postdischarge interventions on breastfeeding outcomes and weight gain among preterm infants. DATA SOURCES: PubMed and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) database were searched for study selection using MeSH terms infant/premature, breastfeeding, weight gain, patient discharge, postnatal care, and counseling. STUDY SELECTION: Inclusion criteria included studies that involved preterm infants who were born less than or equal to 37 weeks of gestation, randomized controlled trials that were in English, conducted in developed countries, and had breastfeeding and weight gain outcomes. A total of 8 articles met inclusion criteria. DATA EXTRACTION: All data related to breastfeeding outcomes including duration, exclusivity, maternal satisfaction, and weight gain were extracted from the randomized controlled trials for the purpose of data synthesis. DATA SYNTHESIS: A total of 310 studies were reviewed. Eight randomized controlled trials met the inclusion criteria. Gestational age of the infants in the studies ranged from 26 to 37 weeks. The results revealed that kangaroo care, peer counseling, in-home breast milk intake measurement, and postdischarge lactation support improved breastfeeding outcomes among preterm infants, and that maternal satisfaction improved with postdischarge interventions. No significant evidence of pre- and postdischarge interventions on weight gain was found. CONCLUSIONS: Pre- and postdischarge interventions were effective in promoting breastfeeding exclusivity, duration, and maternal satisfaction among mothers of preterm infants. These findings have important clinical implications that support the need for evidence-based breastfeeding interventions for preterm infants before discharge and vigilant postdischarge support. Research to determine more effective interventions to promote exclusive and long-term breastfeeding among preterm infants is required.
