These were subcategorised into mild (n = 2,670, 4.8 %), moderate (n = 1,073, 1.9 %) and severe (n = 403, 0.73 %) forms. Median time to diagnosis was 4 (2–6) d after ICU admission, while median time to peak serum sodium level was 5 (3–8) d. The median maximum sodium level across the cohort was 149 (147–152) mmol·L⁻¹. The sodium correction rate was 1 mmol·L⁻¹ per day, taking a median of 3 d (1–5) for sodium levels to return below 145 mmol·L⁻¹. APACHE III score, invasive ventilation, fever, and diuretic use on the day before hypernatremia were independent risk factors for moderate or severe ICU-AH. After adjusting for confounders, all levels of hypernatremia were independently associated with an increased risk of 30-d in-hospital mortality.</div></div><div><h3>Conclusions</h3><div>In a large multicentric study of critically ill patients, ICU-acquired hypernatremia occurred in one in eight admissions after a median of four days in the ICU and was preceded by identifiable and modifiable risk factors. If severe, its correction was slow, and normalisation was delayed. After adjusting for other factors, all levels of hypernatremia were an independent risk factor for 30-d in-hospital mortality.</div></div>","PeriodicalId":49215,"journal":{"name":"Critical Care and Resuscitation","volume":"26 4","pages":"Pages 303-310"},"PeriodicalIF":1.4,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11704424/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142957534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
