目的。本文是一项随机对照试验的报告，旨在检验有针对性的多重干预策略在减少急症护理医院患者跌倒数量方面的有效性。背景。预防患者跌倒仍然是医疗机构面临的一项挑战。尚未确定有针对性的多重跌倒预防干预措施在减少跌倒发生率方面的有效性。方法。 2006 年招募了在跌倒评估工具 Hendrich II 跌倒风险模型中得分为 5 分及以上的患者。被随机分配到干预组的患者接受了有针对性的多种干预措施。两个研究组都接受了病房护士提供的标准跌倒预防干预措施。两组的跌倒发生率均以 95% CI 报告，使用 Wilson 方法计算并使用卡方检验进行比较。使用 Armitage 和 Berry 描述的方法估计相对风险并计算 95% CI。首次坠落事件的时间是使用 Kaplan-Meier 方法构建的。报告的风险比为 95% CI，并使用对数秩检验进行比较。结果。对照组和干预组分别有 912 名和 910 名参与者。对照组和干预组的跌倒发生率分别为1.5%（95% CI：0.9-2.6）和0.4%（95% CI：0.2-1.1）。相对风险估计为 0.29 (95% CI: 0.1-0.87) 有利于干预组。结论。这项研究表明，有针对性的多种干预措施可以有效减少急症护理环境中患者跌倒的发生率。
Aim. This article is a report of a randomized controlled trial to examine the effectiveness of a targeted multiple intervention strategy in reducing the number of patient falls in an acute care hospital.Background. Prevention of patient falls remains a challenge that has eluded healthcare institutions. The effectiveness of targeted multiple fall prevention interventions in reducing the incidences of falling has not been established.Methods. Patients who scored 5 and above on the Hendrich II Fall Risk Model, a fall assessment tool, were recruited in 2006. Patients who were randomized to the intervention group received targeted multiple interventions. Both the research groups received the standard fall prevention interventions from the ward nurses. The rates of fall incidences for both groups were reported with 95% CI, calculated using Wilson method and compared using the Chi-square test. The relative risk was estimated and 95% CI was calculated using the methods described by Armitage and Berry. The times to first fall events were constructed using the Kaplan-Meier method. The hazard ratio was reported at 95% CI and the comparison was made using the log-rank test.Results. There were 912 and 910 participants in the control and intervention groups, respectively. The fall incidence rates were 1.5%(95% CI: 0.9-2.6) and 0.4%(95% CI: 0.2-1.1) in the control and intervention groups, respectively. The relative risk estimate of 0.29 (95% CI: 0.1-0.87) favours the intervention group.Conclusion. This study showed that targeted multiple interventions were effective in reducing the incidences of falls in patients in the acute care setting.
