To synthesise evidence on nurses' roles in long-term care settings and map their interactions.
Systematic review with network analysis.
Thematic synthesis was used to identify nurses' roles, and network analysis mapped their interactions across domains.
Six databases—Cumulative Index to Nursing and Allied Health Literature, PubMed, Embase, Cochrane Library, Research Information Sharing Service and Database of Periodical Information Academic—were searched for peer-reviewed articles from 2014 to 2024. The Mixed Methods Appraisal Tool assessed study quality.
Fifteen studies were included. Nurses' roles spanned six domains: collaboration, education, leadership, resident-centred care, quality improvement and resource management. Network analysis revealed collaboration and leadership as the most central, each with a degree centrality of five, acting as bridges across domains. Three thematic clusters emerged: collaboration and resource management focused on operational teamwork; leadership and quality improvement centred on systemic care enhancements; and education and resident-centered care emphasised training and resident-focused care. A technological competence gap was identified, alongside barriers like staffing shortages and role ambiguity.
Nurses' interconnected roles are critical for resident-centered care; however, they require systemic support to address barriers and technological gaps.
Enhanced interprofessional training, leadership development and digital skill integration can improve care quality and nurse well-being in long-term care settings.
This study addressed the complexity of nurses' roles in long-term care and their structural interactions, finding collaboration and leadership as pivotal with three role clusters and a technological gap, impacting long-term care nurses, educators and policymakers to inform workforce strategies.
