In the subgroup 31.89% of the patients stated alcohol abstinence. About one quarter (25.13%) of patients who denied daily alcohol intake but scored positive on the AUDIT-C displayed levels of alcohol consumption ranging from moderate (11.20%) to high (13.87%) according to the AUDIT-C.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>Reliable information about alcohol consumption is related to the method of questioning. The AUDIT-C evaluates the patient\u00b4s alcohol intake precisely and identifies more older patients with possibly health- and surgery-relevant alcohol consumption levels. The validated AUDIT-C provides an objective assessment to the physician during the pre-clinic anesthesiologic consultation. Additionally, handing out a questionnaire to the patient encourages initiative and self-assessment and could also relieve both, the physician and the patient from sensing a moral evaluation of alcohol consumption.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1186\/s13722-025-00569-8","type":"journal-article","created":{"date-parts":[[2025,5,21]],"date-time":"2025-05-21T06:22:06Z","timestamp":1747808526000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Preoperative evaluation of alcohol consumption in older patients"],"prefix":"10.1186","volume":"20","author":[{"given":"Vera","family":"Guttenthaler","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Wittmann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"Menzenbach","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2025,5,21]]},"reference":[{"key":"569_CR1","unstructured":"WHO.
