Aim Over recent years, there has been considerable progress towards reducing the number of younger people (aged under 65) entering and living in residential aged care. Despite this progress, younger people remain living in residential aged care and should continue to be supported to transition into more age-appropriate care. Methods The report used linked administrative data from the National Aged Care Data Clearinghouse, the National Death Index and the National Disability Insurance Scheme (NDIS). The data linkage enabled analysis of around 73,200 younger people who used aged care services between 1 July 2017 and 30 June 2022, including 12,300 who lived in residential aged care. Results The analysis found, around 2 in 3 younger people living in residential aged care were NDIS participants. Most NDIS participants used aged care services before accessing the NDIS, and many became participants after entering residential aged care. NDIS participants tended to enter residential aged care at younger ages and to stay longer than non-participants. Traumatic brain injury and dementia were common primary disabilities among NDIS participants. Fewer than 1 in 3 participants with Specialist Disability Accommodation funding used this support. More than half of NDIS participants died or turned 65 while living in residential aged care. Conclusion These findings demonstrate how linked data can inform person-centred policy and practice across the aged care and disability sectors.
