This study aims to synthesise and critically review the research on Family-Centred Care interventions in Neonatal Intensive Care Units and neonatal special care units across international, and thereby cross-cultural, settings. An integrative literature review approach was used, with seven databases searched. The search generated 1,741 articles, with forty-eight meeting the inclusion criteria. Physical participation and involvement of families within neonatal care was the most common intervention and was included in studies across most countries, while the concepts of bedside/medical rounds, interdisciplinary family conferences, and partnership were the interventions least reported. Although clinical, family and health service outcomes were measured across studies, they were varied and diverse. Further research on Family-Centred Care interventions and their relevance globally is needed to provide a greater understanding of Family-Centred Care within different contexts.
