Moreover, binary logistic regression methods were used to examine whether the time in intensive care is a predictor of outcome after 1 year. The clinical 1-year outcome was measured prospectively in a 12-month follow-up by telephone interview and categorised by the modified Rankin Scale (mRS). Patients who died during their stay in intensive care were excluded. Complications like pneumonia (\u03b2\u2009=\u20095.11; 95% CI\u2009=\u20091.75\u20138.46; p\u2009=\u20090.0031), sepsis (\u03b2\u2009=\u20099.54; 95% CI\u2009=\u20093.27\u201315.82; p\u2009=\u20090.0031), hydrocephalus (\u03b2\u2009=\u20094.63; 95% CI\u2009=\u20091.82\u20137.45; p\u2009=\u20090.0014), and delayed cerebral ischemia (DCI) (\u03b2\u2009=\u20093.38; 95% CI\u2009=\u20090.19\u20136.56; p\u2009=\u20090.038) were critical factors depending the LOS in intensive care as well as decompressive craniectomy (\u03b2\u2009=\u20095.02; 95% CI\u2009=\u20091.35\u20138.70; p\u2009=\u20090.0077). All analysed comorbidities such as hypertension, diabetes, hypothyroidism, cholesterinemia, and smoking history had no significant impact on the LOS in intensive care. LOS in intensive care (OR\u2009=\u20091.09; 95% CI\u2009=\u20091.03\u20131.15; p\u2009=\u20090.0023) as well as WFNS grade (OR\u2009=\u20093.72; 95% CI\u2009=\u20092.23\u20136.21; p\u2009&lt;\u20090.0001) and age (OR\u2009=\u20091.06; 95% CI\u2009=\u20091.02\u20131.10; p\u2009=\u20090.0061) were significant factors that had an impact on the outcome after 1 year. Complications in intensive care but not comorbidities are associated with higher LOS in intensive care. LOS in intensive care is a modest but significant predictor of outcomes after subarachnoid haemorrhage.<\/jats:p>","DOI":"10.1038\/s41598-020-63298-9","type":"journal-article","created":{"date-parts":[[2020,4,10]],"date-time":"2020-04-10T06:03:08Z","timestamp":1586498588000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Impact of Complications and Comorbidities on the Intensive Care Length of Stay after Aneurysmal Subarachnoid Haemorrhage"],"prefix":"10.1038","volume":"10","author":[{"given":"Alexander","family":"Hammer","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gholamreza","family":"Ranaie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frank","family":"Erbguth","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthias","family":"Hohenhaus","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Wenzl","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6329-8674","authenticated-orcid":false,"given":"Monika","family":"Killer-Oberpfalzer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hans-Herbert","family":"Steiner","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hendrik","family":"Janssen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2020,4,10]]},"reference":[{"key":"63298_CR1","doi-asserted-by":"publisher","first-page":"1007","DOI":"10.1097\/00003246-199506000-00004","volume":"23","author":"NJ Solenski","year":"1995","unstructured":"Solenski, N.
