Therefore, this study aimed to investigate hospital LOS and associated factors in patients with osteoarthritis from Germany. Methods: The present cross-sectional study included patients hospitalized for osteoarthritis in one of fourteen hospitals in Germany between 2018 and 2023 (hospital database; IQVIA). The study outcome was the duration of hospital stay in days. Study covariables included age, sex, hospital department, osteoarthritis type, co-diagnosis, and hospitalization-related procedure. Associations between covariables and hospital LOS were analyzed using hierarchical linear regression models. Results: There were 8770 patients included in the study (mean [standard deviation] age 68.7 [10.8] years; 60.2% women). The mean (standard deviation) hospital LOS was 8.5 (5.0) days. Factors positively and significantly associated with hospital LOS were older age, female sex, orthopedic surgery and other medical specialty departments (compared with other surgery departments), knee and other and unspecified osteoarthritis (compared with hip osteoarthritis), multiple co-diagnoses (e.g., acute posthemorrhagic anemia, other disorders of fluid, electrolyte, and acid\u2013base balance, and disorders of purine and pyrimidine metabolism), and several hospitalization-related procedures (i.e., geriatric rehabilitation, hip arthroplasty, and knee arthroplasty). Conclusions: The mean hospital LOS was higher than eight days in this osteoarthritis population from Germany, with a spectrum of demographic, clinical, and hospitalization-related factors associated with this hospital LOS. In this context, interventions are needed to reduce the LOS of hospitalizations for osteoarthritis in Germany.<\/jats:p>","DOI":"10.3390\/jcm13092628","type":"journal-article","created":{"date-parts":[[2024,4,30]],"date-time":"2024-04-30T04:01:52Z","timestamp":1714449712000},"page":"2628","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Hospital Length of Stay and Associated Factors in Patients with Osteoarthritis from Germany: A Cross-Sectional Study"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2124-7227","authenticated-orcid":false,"given":"Karel","family":"Kostev","sequence":"first","affiliation":[{"name":"Epidemiology, IQVIA, Unterschweinstiege 2-14, 60549 Frankfurt am Main, Germany"},{"name":"University Clinic, Philipps-University, 35037 Marburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6733-1539","authenticated-orcid":false,"given":"Razak M.","family":"Gyasi","sequence":"additional","affiliation":[{"name":"African Population and Health Research Center, Nairobi 00100, Kenya"},{"name":"National Centre for Naturopathic Medicine, Faculty of Health, Southern Cross University, Lismore, NSW 2480, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6798-5092","authenticated-orcid":false,"given":"Marcel","family":"Konrad","sequence":"additional","affiliation":[{"name":"Department of Health and Social, FOM University of Applied Sciences for Economics and Management, 45127 Essen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1628-9948","authenticated-orcid":false,"given":"Dong Keon","family":"Yon","sequence":"additional","affiliation":[{"name":"Center for Digital Health, Medical Science Research Institute, Kyung Hee University College of Medicine, Seoul 02447, Republic of Korea"},{"name":"Department of Regulatory Science, Kyung Hee University, Seoul 02447, Republic of Korea"},{"name":"Department of Pediatrics, Kyung Hee University Medical Center, Kyung Hee University College of Medicine, Seoul 02447, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1071-1239","authenticated-orcid":false,"given":"Louis","family":"Jacob","sequence":"additional","affiliation":[{"name":"Research and Development Unit, Parc Sanitari Sant Joan de D\u00e9u, CIBERSAM, ISCIII, Dr. Antoni Pujadas, 42, 08830 Sant Boi de Llobregat, Spain"},{"name":"AP-HP, Universit\u00e9 Paris Cit\u00e9, Lariboisi\u00e8re-Fernand Widal Hospital, Department of Physical Medicine and Rehabilitation, 75010 Paris, France"},{"name":"Universit\u00e9 Paris Cit\u00e9, Inserm U1153, Epidemiology of Ageing and Neurodegenerative Diseases (EpiAgeing), 75010 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"184","DOI":"10.1016\/j.joca.2021.04.020","article-title":"Epidemiology of osteoarthritis","volume":"30","author":"Allen","year":"2022","journal-title":"Osteoarthr.
