Falls reflect sentinel events in older adults, with significant negative consequences. Although fall risk factors have been identified as intrinsic (e.g., muscle weakness, balance problems) and extrinsic (e.g., home hazards), most prevention programs target only intrinsic factors. We present the rationale and design of a home-based multicomponent fall prevention program-the LIVE LiFE program-for community-living older adults. The program adapts and expands the successful Lifestyle Intervention Functional Exercise (LiFE) program by adding home safety, vision contrast screening, and medication review. The specific aims of the study are to (1) adapt the LiFE program to a US context and expand it into a multicomponent program (LIVE LiFE) addressing intrinsic and extrinsic fall risks, (2) examine feasibility and acceptability, and (3) estimate program impact on multiple outcome measures to prepare for an efficacy trial.
The study involves two phases: an open-label pilot, followed by a two-group, single-blinded randomized pilot trial. Eligible participants are community-living adults 70+ years reporting at least one injurious fall or two non-injurious falls in the previous year. Participants are randomized in a 2:1 ratio to the program group (LIVE LiFE, n = 25) or the control group (written fall risk assessment, n = 12). The open-label pilot participants (n = 3) receive the program without randomization and are assessed based on their experience, resulting in a stronger emphasis on the participant's personal goals being integrated into LIVE LiFE. Fall risk and balance outcomes are assessed by the Timed Up and Go and the 4-Stage Balance Test at 16 weeks. Additional outcomes are incidence of falls and near falls, falls efficacy, fear of falling, number of home hazards, and medications assessed at 16 weeks. Incidence of falls and near falls, program adherence, and satisfaction are assessed again at 32 weeks.
By expanding and adapting the evidence-based LiFE program, our study will help us understand the feasibility of conducting a multicomponent program and estimate its impact on multiple outcome measures. This will support moving forward with an efficacy trial of the LIVE LiFE program for older adults who are at risk of falling.

跌倒反映了老年人中的重大不良事件,会产生严重的负面后果。尽管已确定跌倒风险因素分为内在因素(如肌肉无力、平衡问题)和外在因素(如家庭危险因素),但大多数预防计划仅针对内在因素。我们介绍了一项针对社区居住老年人的居家多组分跌倒预防计划——LIVE LiFE计划的基本原理和设计。该计划通过增加家庭安全、视力对比度筛查和药物审查,对成功的生活方式干预功能锻炼(LiFE)计划进行了调整和扩展。该研究的具体目标是:(1)将LiFE计划调整至美国背景并扩展为一个解决内在和外在跌倒风险的多组分计划(LIVE LiFE);(2)检验可行性和可接受性;(3)评估该计划对多种结局指标的影响,为疗效试验做准备。
该研究包括两个阶段:开放标签试点阶段,随后是两组单盲随机试点试验。符合条件的参与者是年龄在70岁及以上、报告在前一年至少发生过一次伤害性跌倒或两次非伤害性跌倒的社区居住成年人。参与者按2:1的比例随机分为计划组(LIVE LiFE,n = 25)或对照组(书面跌倒风险评估,n = 12)。开放标签试点参与者(n = 3)不经过随机分组接受该计划,并根据他们的体验进行评估,从而更加强调将参与者的个人目标纳入LIVE LiFE计划。在16周时通过计时起立行走测试和四阶段平衡测试评估跌倒风险和平衡结局。其他结局指标包括跌倒和险些跌倒的发生率、跌倒效能、跌倒恐惧、家庭危险因素数量以及在16周时评估的药物。在32周时再次评估跌倒和险些跌倒的发生率、计划依从性和满意度。
通过扩展和调整基于证据的LiFE计划,我们的研究将帮助我们了解开展多组分计划的可行性,并评估其对多种结局指标的影响。这将支持推进针对有跌倒风险的老年人的LIVE LiFE计划的疗效试验。
