The ROSA has also examined the experience of individuals with highly prevalent and understudied conditions in aged care settings (eg, eye and mental health) and aspects of services (eg, built environment) and innovation (eg, mobile radiological services) that can affect older people\u2019s health. Important learnings from the ROSA\u2019s development include the significant resources and multidisciplinary expertise required for establishing this platform. Between 2018 and 2022, 43 academic publications, eight reports of the Australian Government Royal Commission into Aged Care Quality and Safety, and several reports to state health authorities and professional societies have used the ROSA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Future plans<\/jats:title>\n                    <jats:p>Our plans include to: (1) continue delivering high-quality evidence to support the improvement of ageing and aged care services; (2) influence and improve the quality of research in and for the aged care sector; (3) expand scope to facilitate examining aims in more depth; (4) include future aged care sector data collections within the ROSA; (5) inform best practices and innovate how consumer engagement occurs in research; (6) monitor and evaluate the impact of the 2021 Australian Aged Care Reforms.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1136\/bmjopen-2022-066390","type":"journal-article","created":{"date-parts":[[2022,11,17]],"date-time":"2022-11-17T09:31:54Z","timestamp":1668677514000},"page":"e066390","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":48,"title":["Registry of Senior Australians (ROSA): integrating cross-sectoral information to evaluate quality and safety of care provided to older people"],"prefix":"10.1136","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8261-2665","authenticated-orcid":false,"given":"Maria C","family":"Inacio","sequence":"first","affiliation":[{"name":"Registry of Older South Australians, South Australian Health and Medical Research Institute, Adelaide, South Australia, Australia"},{"name":"UniSA Allied Health and Human Performance, University of South Australia, Adelaide, South Australia, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1192-4121","authenticated-orcid":false,"given":"Gillian Elizabeth","family":"Caughey","sequence":"additional","affiliation":[{"name":"Registry of Older South Australians, South Australian Health and Medical Research Institute, Adelaide, South Australia, Australia"},{"name":"UniSA Allied Health and Human Performance, University of South Australia, Adelaide, South Australia, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steve","family":"Wesselingh","sequence":"additional","affiliation":[{"name":"South Australian Health and Medical Research Institute, Adelaide, South Australia, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2022,11,17]]},"reference":[{"key":"2025121603350569000_12.11.e066390.1","unstructured":"Organisation for Economic Co-operation and Development .
