Although guidelines recommend systematic screening and assessment, delirium is often unrecognised, undiagnosed and uncoded. There is a lack of valid data on this patient safety indicator in German\u2010speaking countries.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The study was conducted in a tertiary care hospital in Switzerland on 5 July 2022. Specially trained registered nurses collected data from all patients meeting the inclusion criteria using CAM, ICDSC or mCAM\u2010ED. Data were analysed descriptively with stratification by delirium status, setting and surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The point prevalence across all settings was 6.9% (27\/390), with large variation between settings: ICU 28.6% (4\/14), IMC 28.0% (7\/25), wards 4.6% (15\/326) and ED 4% (1\/25). Surgical patients were almost twice as likely to be affected as medical patients (8.9% vs. 4.8%). Patients with delirium differed most clearly from those without by having a larger number of ICD\u201010\u2009F\u2010diagnoses, a larger number of medications and higher age, which are known risk factors. Moreover, those with delirium had more missed diagnoses, increased mortality, more adverse events and higher costs.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>A significant number of patients experienced delirium and adverse clinical outcomes. Missed delirium diagnoses may further jeopardise patient safety and result in lost revenue. It remains unclear to what extent the risk factors and effects of delirium are causal and what determinants underlie missed diagnoses.<\/jats:p><\/jats:sec><jats:sec><jats:title>Relevance to Clinical Practice<\/jats:title><jats:p>Consistent identification of high\u2010risk patients and treatment settings with elevated risk, accompanied by the implementation of effective preventive and management strategies, is critical to addressing delirium.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jocn.17113","type":"journal-article","created":{"date-parts":[[2024,3,14]],"date-time":"2024-03-14T04:51:49Z","timestamp":1710391909000},"page":"921-931","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Prevalence, risk factors and impact of delirium in adult inpatients in a tertiary care hospital: A point prevalence study"],"prefix":"10.1111","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7762-2081","authenticated-orcid":false,"given":"Cornel","family":"Schiess","sequence":"first","affiliation":[{"name":"Department of Nursing and Allied Health Care Professions University Hospital Zurich  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lisa","family":"Hofer","sequence":"additional","affiliation":[{"name":"Research Associate Epidemiology Biostatistics and Prevention Institute, University Zurich  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5264-6394","authenticated-orcid":false,"given":"Stefanie","family":"von Felten","sequence":"additional","affiliation":[{"name":"Research Associate Epidemiology Biostatistics and Prevention Institute, University Zurich  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"Bartussek","sequence":"additional","affiliation":[{"name":"Institute of Intensive Care Medicine, University Hospital Zurich  Zurich Switzerland"},{"name":"Department for Quantitative Biomedicine University of Zurich  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5220-4273","authenticated-orcid":false,"given":"Heidi","family":"Petry","sequence":"additional","affiliation":[{"name":"Head of Center of Clinical Nursing Science University Hospital Zurich  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7619-8314","authenticated-orcid":false,"given":"Jutta","family":"Ernst","sequence":"additional","affiliation":[{"name":"Research Associate, Center of Clinical Nursing Science University Hospital Zurich  Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,3,13]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00198\u2010019\u201005172\u20107"},{"key":"e_1_2_13_3_1","doi-asserted-by":"publisher","DOI":"10.1136\/emermed\u20102011\u2010200586"},{"key":"e_1_2_13_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.iccn.2020.102925"},{"key":"e_1_2_13_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s001340100909"},{"key":"e_1_2_13_6_1","volume-title":"Internationale statistische Klassifikation der Krankheiten und verwandter Gesundheitsprobleme: 10 Revision","author":"Bundesinstitut f\u00fcr Arzneimittel und Medizinprodukte","year":"2022"},{"key":"e_1_2_13_7_1","volume-title":"Statistical power analysis for the behavioral sciences","author":"Cohen J.","year":"1998"},{"key":"e_1_2_13_8_1","unstructured":"Deutsche Gesellschaft f\u00fcr Neurologie (DNG).
