A major reason cited for continued restraint use in American nursing homes is the widely held belief that restraint reduction will lead to fall-related incidents and injuries.
This study represents an analysis of data collected in a clinical trial of interventions aimed at reducing the use of restraints in nursing homes. Two different designs were employed to test the relationship between restraint reduction and falls/injuries. First, multiple logistic regression was used to compare fall/injury rates in subjects who had restraints removed (n = 38) to those who continued to be restrained (n = 88); second, survival analysis was employed to test the relationship between physical restraint removal and falls/injuries at the institutional level by comparing fall/injury rates among three nursing homes (n = 633) with varying rates of restraint reduction.
Based on the multiple logistic regression analysis, there was no indication of increased risk of falls or injuries with restraint removal. Moreover, restraint removal significantly decreased the chance of minor injuries due to falls (adjusted odds ratio: 0.3, 95% CI: 0.1, 0.9; p < .05). The survival analysis demonstrated that the nursing home that had the least restraint reduction (11%) had a 50% higher rate of falls (p < .01) and more than twice the rate of fall-related minor injuries (p < .001) when compared to the homes with 23% and 56% restraint reduction, respectively.
Physical restraint removal does not lead to increases in falls or subsequent fall-related injury in older nursing home residents.
在美国养老院中,持续使用约束措施的一个主要原因是人们普遍认为减少约束会导致与跌倒相关的事件和伤害。
本研究对一项旨在减少养老院约束措施使用的临床试验中收集的数据进行了分析。采用了两种不同的设计来测试减少约束与跌倒/伤害之间的关系。首先,使用多元逻辑回归比较去除约束的受试者(n = 38)与继续使用约束的受试者(n = 88)的跌倒/伤害率;其次,通过比较三家约束减少率不同的养老院(n = 633)的跌倒/伤害率,采用生存分析来测试机构层面去除身体约束与跌倒/伤害之间的关系。
基于多元逻辑回归分析,没有迹象表明去除约束会增加跌倒或受伤的风险。此外,去除约束显著降低了因跌倒导致轻伤的几率(调整后的优势比:0.3,95%置信区间:0.1,0.9;p <.05)。生存分析表明,与约束减少率分别为23%和56%的养老院相比,约束减少最少(11%)的养老院跌倒率高50%(p <.01),与跌倒相关的轻伤率是其两倍多(p <.001)。
去除身体约束不会导致老年养老院居民跌倒或随后与跌倒相关的伤害增加。
