BACKGROUND AND OBJECTIVES: Preterm and low birth weight (LBW) infants are often separated from parents during hospitalization. Our objective was to assess effects of interventions to increase family involvement in the routine newborn care of preterm or LBW infants compared with standard NICU care on infant and parental outcomes. METHODS: Data sources include Medline, Embase, CINAHL, and World Health Organization Global Index Medicus to August 2021. The study selection included randomized controlled trials (RCTs) of family involvement intervention packages. Data were extracted and pooled with random-effects models. RESULTS: We included 15 RCTs with 5240 participants. All interventions included direct parental bedside care; packages varied with respect to additional components. Family involvement interventions decreased retinopathy of prematurity (odds ratio 0.52, 95% confidence interval CI: 0.34, 0.80; 8 RCTs), length of hospital stay (mean difference MD -2.91 days; 95% CI: -5.15,-0.82; 11 RCTs), and parental stress and anxiety (Parental Stress Scale: MD -0.29 points, 95% CI: -0.56,-0.01, 2 RCTs; Anxiety State-Trait scale: MD -1.79, 95% CI: -3.11,-0.48; 2 RCTs). Family involvement increased weight gain velocity (MD 2.09 g/day; 95% CI: 1.27, 2.91; 3 RCTs), neurobehavioral exam scores (MD: 1.11; 95% CI: 0.21, 2.01; 2 RCTs) and predominant or exclusive breastmilk intake (odds ratio 1.34; 95% CI: 1.01, 1.65; 3 RCTs). It may decrease rates of bronchopulmonary dysplasia, infection, and intraventricular hemorrhage. There were no effects on mortality or necrotizing enterocolitis. Certainty of evidence ranged from low to moderate. CONCLUSIONS: Family involvement has a beneficial role on several infant and parental outcomes.
