Accidental hypothermia: Factors related to a prolonged hospital stay – A nationwide observational study in Japan

The incidence of accidental hypothermia (AH) is low, and the length hospital stay in patients with AH remains poorly understood. present study explored which factors were related to prolonged hospitalization among using Japan's nationwide registry data. data from Hypothermia STUDY 2018, included ≥18 years old a body temperature ≤ 35 °C, obtained multicenter for conducted at 89 institutions throughout Japan, collected December 1, February 28, 2019. divided into “short-stay patients” group (within 7 days) “long-stay (more than days). A logistic regression analysis after multiple imputation was performed obtain odds ratios (ORs) age, frailty, location, causes underlying hypothermia, temperature, pH, potassium level, disseminated intravascular coagulation (DIC) score as independent variables. In total, 656 study, 362 eligible analysis. median 17 days. Of patients, 265 (73.2%) stayed more associated frailty (OR, 2.11; 95% confidence interval [CI], 1.09–4.10; p = 0.027), occurrence indoor 3.20; CI, 1.58–6.46; 0.001), alcohol intoxication 0.17; 0.05–0.56; 0.004), pH 0.07; 0.01–0.76; 0.029), level 1.36; 1.00–1.85; 0.048), DIC 1.54; 1.13–2.10; 0.006). Frailty, situation, intoxication, value, contributing AH. Preventing may help reduce addition, measuring value by an arterial blood gas ED recommended early evaluation
