While the reduction in fall rates has not kept pace with the reduction of other hospital-acquired conditions, patient safety research and quality improvement (QI) initiatives at the system and hospital levels have achieved positive results and provide insights into potentially effective risk reduction strategies. An academic medical center developed a QI-based multicomponent strategy for fall prevention and pilot tested it for six months in three high-risk units-the Neuroscience Acute Care Unit, the Myelosuppression/Stem Cell Transplant Unit, and the Acute Care for the Elderly Unit-before implementing and evaluating the strategy hospitalwide.
The multicomponent fall strategy was evaluated using a pre-post study design. The main outcome measures were falls and falls with harm measured in events per 1,000 patient-days. Fall rates were monitored and compared for three classes of falls: (1) accidental, (2) anticipated physiologic, and (3) unanticipated physiologic.
Statistical process control charts showed that the pilot units had achieved significant reductions in falls with harm during the last five months of data collection. Wald test and segmented regression analyses revealed significant improvements in pooled postintervention fall rates, stratified by fall type. The hospitalwide implementation of the program resulted in a 47% overall reduction in falls in the postintervention period.
A fall prevention strategy that targeted the spectrum of risk factors produced measurable improvement in fall rates and rates of patient harm. Hospitals must continue developing, rigorously testing, and sharing their results and experiences in implementing and sustaining multicomponent fall prevention strategies.
虽然跌倒率的降低未能与其他医院获得性疾病的减少保持同步,但系统和医院层面的患者安全研究及质量改进(QI)举措已取得积极成果,并为潜在有效的风险降低策略提供了见解。一家学术医疗中心制定了一项基于QI的多组分跌倒预防策略,并在三个高风险科室——神经科学急性护理科、骨髓抑制/干细胞移植科和老年急性护理科——进行了为期六个月的试点测试,然后在全院实施并评估该策略。
采用前后对照研究设计对多组分跌倒策略进行评估。主要结局指标为跌倒及跌倒致伤,以每1000患者日的事件数衡量。监测并比较三类跌倒的发生率:(1)意外跌倒,(2)预期生理跌倒,(3)非预期生理跌倒。
统计过程控制图显示,在数据收集的最后五个月,试点科室的跌倒致伤率显著降低。Wald检验和分段回归分析显示,按跌倒类型分层的综合干预后跌倒率有显著改善。该项目在全院实施后,干预后期跌倒总数总体下降了47%。
针对一系列风险因素的跌倒预防策略在跌倒率和患者伤害率方面取得了可衡量的改善。医院必须继续制定、严格测试并分享其在实施和维持多组分跌倒预防策略方面的结果和经验。
