BACKGROUND/OBJECTIVES: Family-centered care (FCC) is the recommended model for pediatric inpatient care. Our overall aim was to conduct a narrative synthesis of the contemporary published research on the effectiveness of FCC interventions for pediatric inpatients. Our specific objective was to critique studies of inpatient pediatric FCC interventions that evaluated child or parent outcomes. METHODS: We searched five databases (Pubmed, CINAHL, Embase, PsychInfo, and Web of Science) for peer-reviewed research published from 1 January 2017 to 6 February 2024. Independent reviewers evaluated each study based on pre-specified inclusion and exclusion criteria, then extracted and narratively synthesized the data. RESULTS: We found 16 studies of 15 interventions conducted in six countries. The studies were quantitative (n = 11), qualitative (n = 3), and mixed methods (n = 2), with most designs being of low to moderate quality based on a modified Mixed-Methods Appraisal Tool. Interventions included family-centered rounds, parent-focused health information technology, education, patient navigation, parent-peer support, partnership, and parent participation in caregiving. Most studies found significant improvements in parents well-being, knowledge, and participation, as well as decreased stress and anxiety with the FCC interventions compared to usual care. One study found no differences in child outcomes (infant feeding, length of stay) between usual care and a parent-participation intervention. CONCLUSIONS: Although FCC interventions led to many improved outcomes for parents, there were few well-designed comparison studies using validated tools and well-defined interventions. Higher quality research is needed to promote greater uptake and sustainability of FCC interventions globally.
