We prospectively identified 102 mechanically restrained hospital patients and determined their hospital course. The cohort was elderly, cognitively impaired with multiple chronic diseases. The in-hospital mortality was 21 percent. Nosocomial infection developed in 12 percent and new pressure sores in 22 percent. Prolonged use of restraints (greater than 4 days) was the strongest independent predictor of nosocomial infection (relative risk 1.8, 95% CI = 1.2, 2.8) and new pressure sores (RR 1.4, 95% CI = 1.1, 1.8) as determined by multiple logistic regression analysis. Patients placed in mechanical restraints for longer than four days experience frequent morbid events and should be monitored carefully.
我们前瞻性地识别了102名在医院接受机械约束的患者,并确定了他们的住院病程。该队列患者为老年人,患有多种慢性病且存在认知障碍。住院死亡率为21%。医院感染发生率为12%,新发压疮发生率为22%。通过多因素逻辑回归分析确定,长时间使用约束(超过4天)是医院感染(相对风险1.8,95%可信区间=1.2,2.8)和新发压疮(相对风险1.4,95%可信区间=1.1,1.8)的最强独立预测因素。接受机械约束超过四天的患者经常发生不良事件,应予以密切监测。
