Participants were older community care-recipients from 5 European countries. The outcome measure was mean 6-months total societal costs of resource utilisation (healthcare and informal care). Potential predictors included sociodemographic characteristics, functional limitations, clinical conditions, and diseases\/disorders. The model was developed by performing Linear Mixed Models with a random intercept for the effect of country and validated by an internal-external validation procedure. Living alone, caregiver distress, (I)ADL impairment, required level of care support, health instability, presence of pain, behavioural problems, urinary incontinence and multimorbidity significantly predicted societal costs during 6\u2009months. The model explained 32% of the variation within societal costs and showed good calibration in Iceland, Finland and Germany. Minor model adaptations improved model performance in The Netherland and Italy. The results can provide a valuable orientation for policymakers to better understand cost development among older community care-recipients. Despite substantial differences of countries\u2019 care systems, a validated cross-national set of key predictors could be identified.<\/jats:p>","DOI":"10.1177\/1178632920980462","type":"journal-article","created":{"date-parts":[[2020,12,23]],"date-time":"2020-12-23T23:34:43Z","timestamp":1608766483000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Development and Validation of a Prediction Model for 6-Month Societal Costs in Older Community Care-Recipients in Multiple Countries; the IBenC Study"],"prefix":"10.1177","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5707-2345","authenticated-orcid":false,"given":"Lisanne I","family":"van Lier","sequence":"first","affiliation":[{"name":"Department of General Practice and Medicine of Older People, Amsterdam Public Health Research Institute, Amsterdam UMC, Vrije Universiteit Amsterdam, Amsterdam, and Department on Aging, Netherlands Institute of Mental Health and Addiction (Trimbos Institute), Utrecht, Utrecht, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Judith E","family":"Bosmans","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, Faculty of Science, Amsterdam Public Health Research Institute, Vrije Universiteit Amsterdam, Amsterdam, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Henri\u00ebtte G","family":"van der Roest","sequence":"additional","affiliation":[{"name":"Department of General Practice and Medicine of Older People, Amsterdam Public Health Research Institute, Amsterdam UMC, Vrije Universiteit Amsterdam, Amsterdam, and Department on Aging, Netherlands Institute of Mental Health and Addiction (Trimbos Institute), Utrecht, Utrecht, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martijn W","family":"Heymans","sequence":"additional","affiliation":[{"name":"Department of Epidemiology and Data Science, Amsterdam Public Health Research Institute, Amsterdam UMC, Vrije Universiteit Amsterdam, Amsterdam, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vjenka","family":"Garms-Homolov\u00e1","sequence":"additional","affiliation":[{"name":"Department III, Economy and Law, Hochschule f\u00fcr Technik und Wirtschaft Berlin, Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anja","family":"Declercq","sequence":"additional","affiliation":[{"name":"LUCAS, Centre for Care Research and Consultancy, and CESO, Center for Sociological Research, KU Leuven (University of Leuven), Leuven, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P\u00e1lmi","family":"V J\u00f3nsson","sequence":"additional","affiliation":[{"name":"Department of Geriatrics, Landspitali University Hospital, Faculty of Medicine, University of Iceland, Reykjavik, Iceland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hein PJ","family":"van Hout","sequence":"additional","affiliation":[{"name":"Department of General Practice and Medicine of Older People, Amsterdam Public Health Research Institute, Amsterdam UMC, Vrije Universiteit Amsterdam, Amsterdam, and Department on Aging, Netherlands Institute of Mental Health and Addiction (Trimbos Institute), Utrecht, Utrecht, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,12,23]]},"reference":[{"key":"bibr1-1178632920980462","volume-title":"The Greying of the Baby Boomers.
