This study aimed to quantify healthcare utilization associated with comorbidity that is common in people living with dementia. We conducted a cohort study using population-based data from Hong Kong public hospitals. Individuals aged 35+ with a dementia diagnosis between 2010 and 2019 were included. Among 88,151 participants, people with at least two comorbidities accounted for 81.2%. Estimates from negative binomial regressions showed that compared to those with one or no comorbid condition other than dementia, adjusted rate ratios of hospitalizations among individuals with six or seven and eight or more conditions were 1.97 [98.75% CI, 1.89\u20132.05] and 2.74 [2.63\u20132.86], respectively; adjusted rate ratios of Accident and Emergency department visits among individuals with six or seven and eight or more conditions were 1.53 [1.44\u20131.63] and 1.92 [1.80\u20132.05], respectively. Comorbid chronic kidney diseases were associated with the highest adjusted rate ratios of hospitalizations (1.81 [1.74\u20131.89]), whereas comorbid chronic ulcer of the skin was associated with the highest adjusted rate ratios of Accident and Emergency department visits (1.73 [1.61\u20131.85]). Healthcare utilization for individuals with dementia differed substantially by both the number of comorbid chronic conditions and the presence of some specific comorbid conditions. These findings further highlight the importance of taking account of multiple long-term conditions in tailoring the care approach and developing healthcare plans for people with dementia.<\/jats:p>","DOI":"10.1177\/14713012231177593","type":"journal-article","created":{"date-parts":[[2023,5,22]],"date-time":"2023-05-22T03:34:07Z","timestamp":1684726447000},"page":"422-437","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Association of Comorbidity With Healthcare Utilization in People Living With Dementia, 2010\u20132019: A Population-Based Cohort Study"],"prefix":"10.1177","volume":"23","author":[{"given":"Yingyang","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Social Work and Social Administration, The University of Hong Kong, Hong Kong, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4261-3414","authenticated-orcid":false,"given":"Hao","family":"Luo","sequence":"additional","affiliation":[{"name":"Department of Social Work and Social Administration; Sau Po Centre on Ageing, The University of Hong Kong, Hong Kong, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Terry YS","family":"Lum","sequence":"additional","affiliation":[{"name":"Department of Social Work and Social Administration; Sau Po Centre on Ageing, The University of Hong Kong, Hong Kong, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1427-0215","authenticated-orcid":false,"given":"Martin","family":"Knapp","sequence":"additional","affiliation":[{"name":"Department of Health Policy, London School of Economics and Political Science, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Davide L","family":"Vetrano","sequence":"additional","affiliation":[{"name":"Aging Research Center, NVS Department, Karolinska Institutet, Stockholm University, Stockholm, Sweden; Stockholm Gerontology Research Center, Stockholm, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Celine CS","family":"Chui","sequence":"additional","affiliation":[{"name":"School of Nursing, The University of Hong Kong, Hong Kong, China; School of Public Health, The University of Hong Kong, Hong Kong, China; Laboratory of Data Discovery for Health (D24H), Hong Kong Science and Technology Park, Hong Kong, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pengcheng","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Social Work and Social Administration, The University of Hong Kong, Hong Kong, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1331-942X","authenticated-orcid":false,"given":"Gloria HY","family":"Wong","sequence":"additional","affiliation":[{"name":"Department of Social Work and Social Administration; Sau Po Centre on Ageing, The University of Hong Kong, Hong Kong, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2023,5,22]]},"reference":[{"key":"bibr1-14713012231177593","doi-asserted-by":"publisher","DOI":"10.1186\/s12877-020-01835-x"},{"key":"bibr2-14713012231177593","doi-asserted-by":"publisher","DOI":"10.3390\/jcm9124001"},{"key":"bibr3-14713012231177593","doi-asserted-by":"publisher","DOI":"10.1111\/jgs.16636"},{"key":"bibr4-14713012231177593","doi-asserted-by":"publisher","DOI":"10.1136\/bmjopen-2016-012546"},{"key":"bibr5-14713012231177593","doi-asserted-by":"publisher","DOI":"10.1136\/bmjopen-2016-013067"},{"key":"bibr6-14713012231177593","doi-asserted-by":"publisher","DOI":"10.1186\/s12916-014-0192-4"},{"key":"bibr7-14713012231177593","doi-asserted-by":"publisher","DOI":"10.3310\/hsdr04080"},{"issue":"10","key":"bibr8-14713012231177593","first-page":"1417","volume":"72","author":"Calder\u00f3n-Larranaga A.","year":"2017","journal-title":"The Journals of Gerontology.
