MATERIALS AND METHODS Cohort comprised of adult patients with an intensive care unit (ICU) stay ≥24-h (years 2010-2018). SI ≥0.9 exposure was evaluated via cumulative minutes or time-weighted average; SBP ≤100-mmHg was analyzed. Outcomes were in-hospital mortality, acute kidney injury (AKI), and myocardial injury. RESULTS 18,197 patients from 82 hospitals were analyzed. Any single SI ≥0.9 within the ICU predicted mortality with 90.8% sensitivity and 36.8% specificity. Every 0.1-unit increase in maximum-SI during the first 24-h increased the odds of mortality by 4.8% [95%CI; 2.6-7.0%; p less then .001]. Every 4-h exposure to SI ≥0.9 increased the odds of death by 5.8% [95%CI; 4.6-7.0%; p less then .001], AKI by 4.3% [95%CI; 3.7-4.9%; p less then .001] and myocardial injury by 2.1% [95%CI; 1.2-3.1%; p less then .001]. ≥2-h exposure to SBP ≤100-mmHg was significantly associated with mortality. CONCLUSIONS A single SI reading ≥0.9 is a poor predictor of mortality; cumulative SI exposure is associated with greater risk of mortality/morbidity. The associations with in-hospital mortality were comparable for SI ≥0.9 or SBP ≤100-mmHg exposure. Dynamic interactions between hemodynamic variables need further evaluation among critically ill patients. BACKGROUND End-of-life care in nursing homes holds several risk factors for the use of physical restraints on residents, a practice shown to be neither safe nor effective. OBJECTIVES To determine the frequency of physical limb and/or trunk restraint use in the last week of life of nursing home residents in six European countries and its association with country, resident and nursing home characteristics.
