The objective of this study was to examine associations between the individual characteristics of older adults living with dementia and recurrent ED visits.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We used health administrative databases to conduct a population\u2010based retrospective cohort study among older adults with dementia in Ontario, Canada. We included community\u2010dwelling adults 66\u2009years and older who visited the ED between April 1, 2010, and March 31, 2019 and were discharged home. We recorded all ED visits within one year after the baseline visit. We used recurrent event Cox regression to examine associations between repeat ED visits and individual clinical, demographic, and health service use characteristics. We fit conditional inference trees to identify the most important factors and define subgroups of varying risk.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Our cohort included 175,863 older adults with dementia. ED use in the year prior to baseline had the strongest association with recurrent visits (3+\u2009vs.0 adjusted hazard ratio (aHR): 1.92 (1.89, 1.94), 2vs.0 aHR: 1.45 (1.43, 1.47), 1vs.0 aHR: 1.23 (1.21, 1.24)). The conditional inference tree utilized history of ED visits and comorbidity count to define 12 subgroups with ED revisit rates ranging from 0.79 to 7.27 per year. Older adults in higher risk groups were more likely to live in rural and low\u2010income areas and had higher use of anticonvulsants, antipsychotics, and benzodiazepines.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>History of ED visits may be a useful measure to identify older adults with dementia who would benefit from additional interventions and supports. A substantial proportion of older adults with dementia have a pattern of recurrent visits and may benefit from dementia\u2010friendly and geriatric\u2010focused EDs. Collaborative medication review in the ED and closer follow\u2010up and engagement with community supports could improve patient care and experience.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/jgs.18457","type":"journal-article","created":{"date-parts":[[2023,6,14]],"date-time":"2023-06-14T08:15:40Z","timestamp":1686730540000},"page":"3731-3743","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Factors associated with recurrent emergency department visits among people living with dementia: A retrospective cohort study"],"prefix":"10.1111","volume":"71","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6282-3614","authenticated-orcid":false,"given":"Aaron","family":"Jones","sequence":"first","affiliation":[{"name":"Department of Health Research Methods, Evidence, and Impact McMaster University  Hamilton Ontario Canada"},{"name":"ICES  Toronto Ontario Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5296-6013","authenticated-orcid":false,"given":"Jennifer A.","family":"Watt","sequence":"additional","affiliation":[{"name":"ICES  Toronto Ontario Canada"},{"name":"Li Ka Shing Knowledge Institute St. Michael's Hospital, Unity Health Toronto  Toronto Ontario Canada"},{"name":"Division of Geriatric Medicine, Department of Medicine University of Toronto  Toronto Ontario Canada"},{"name":"Institute of Health Policy, Management &amp; Evaluation, Dalla Lana School of Public Health University of Toronto  Toronto Ontario Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura C.","family":"Maclagan","sequence":"additional","affiliation":[{"name":"ICES  Toronto Ontario Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sarah","family":"Swayze","sequence":"additional","affiliation":[{"name":"ICES  Toronto Ontario Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liisa","family":"Jaakkimainen","sequence":"additional","affiliation":[{"name":"ICES  Toronto Ontario Canada"},{"name":"Institute of Health Policy, Management &amp; Evaluation, Dalla Lana School of Public Health University of Toronto  Toronto Ontario Canada"},{"name":"Sunnybrook Research Institute Sunnybrook Health Sciences Centre  Toronto Ontario Canada"},{"name":"Department of Family and Community Medicine University of Toronto  Toronto Ontario Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael J.","family":"Schull","sequence":"additional","affiliation":[{"name":"ICES  Toronto Ontario Canada"},{"name":"Institute of Health Policy, Management &amp; Evaluation, Dalla Lana School of Public Health University of Toronto  Toronto Ontario Canada"},{"name":"Sunnybrook Research Institute Sunnybrook Health Sciences Centre  Toronto Ontario Canada"},{"name":"Department of Medicine University of Toronto  Toronto Ontario Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7341-0655","authenticated-orcid":false,"given":"Susan E.","family":"Bronskill","sequence":"additional","affiliation":[{"name":"ICES  Toronto Ontario Canada"},{"name":"Institute of Health Policy, Management &amp; Evaluation, Dalla Lana School of Public Health University of Toronto  Toronto Ontario Canada"},{"name":"Sunnybrook Research Institute Sunnybrook Health Sciences Centre  Toronto Ontario Canada"},{"name":"Women's College Research Institute Women's College Hospital  Toronto Ontario Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,6,14]]},"reference":[{"key":"e_1_2_11_2_1","unstructured":"PattersonC.World Alzheimer report 2018.
