Reconsidering hospital transfers from residential aged care: A scoping review of determinants, prevalence, and system-level solutions in Australia

To identify the determinants, prevalence, and proposed solutions for potentially avoidable hospital transfers (PAHT) of residential aged care facility (RACF) residents in Australia, a scoping review was conducted using PubMed, CINAHL, Cochrane Library and Google Scholar, covering the period from 2015 to 2025. The database search identified 1350 articles, of which 43 studies met inclusion criteria. Prevalence of PAHT ranged from of 8.5% to 95.2% when defined as specific conditions manageable by an outreach service; from 2.2% to 55.6% when defined as potentially manageable with primary care; and from 11.6% to 53% when defined as an Emergency Department (ED) presentation not requiring a hospital admission. The most frequently reported determinant of PAHT pertained to the overarching theme of RACF clinical decision-making and systemic RACF practice-based factors. Establishment of, and access to, outreach services was the main proposed solution, alongside onsite General Practitioners (GP), Advance Care Planning (ACP), and capacity building for RACF nurses. Despite Australia’s diversity, our findings demonstrate patterns and similarities in prevalence, determinants and solutions. Consensus or standardisation of denominators would enhance comparability of outcomes across studies. These findings offer opportunities to reconsider solutions in response to the chronic challenge of avoidable nursing home patient transfers.
