Common foot problems are independent risk factors for falls in older people. There is evidence that podiatry can prevent falls in community-dwelling populations. The feasibility of implementing a podiatry intervention and trial in the care home population is unknown. To inform a potential future definitive trial, we performed a pilot randomised controlled trial to assess: (i) the feasibility of a trial of a podiatry intervention to reduce care home falls, and (ii) the potential direction and magnitude of the effect of the intervention in terms of number of falls in care home residents.
Informed by Medical Research Council guidance on developing and evaluating complex interventions, we conducted a single blind, pilot randomised controlled trial in six care homes in the East of Scotland. Participants were randomised to either: (i) a three month podiatry intervention comprising core podiatry care, foot and ankle exercises, orthoses and footwear provision or (ii) usual care. Falls-related outcomes (number of falls, time to first fall) and feasibility-related outcomes (recruitment, retention, adherence, data collection rates) were collected. Secondary outcomes included: generic health status, balance, mobility, falls efficacy, and ankle joint strength.
474 care home residents were screened. 43 (9.1%) participants were recruited: 23 to the intervention, 20 to control. Nine (21%) participants were lost to follow-up due to declining health or death. It was feasible to deliver the trial elements in the care home setting. 35% of participants completed the exercise programme. 48% reported using the orthoses 'all or most of the time'. Completion rates of the outcome measures were between 93% and 100%. No adverse events were reported. At the nine month follow-up period, the intervention group per-person fall rate was 0.77 falls vs. 0.83 falls in the control group.
A podiatry intervention to reduce falls can be delivered to care home residents within a pilot randomised controlled trial of the intervention. Although not powered to determine effectiveness, these preliminary data provide justification for a larger trial, incorporating a full process evaluation, to determine whether this intervention can significantly reduce falls in this high-risk population.

常见足部问题是老年人跌倒的独立危险因素。有证据表明,足病治疗可预防社区居住人群跌倒。在养老院人群中实施足病治疗干预及试验的可行性尚不清楚。为了为未来可能的确定性试验提供信息,我们进行了一项试点随机对照试验,以评估:(i)一项足病治疗干预试验以减少养老院跌倒的可行性,以及(ii)就养老院居民跌倒次数而言,该干预措施效果的潜在方向和程度。
根据医学研究委员会关于开发和评估复杂干预措施的指南,我们在苏格兰东部的六家养老院进行了一项单盲试点随机对照试验。参与者被随机分为:(i)为期三个月的足病治疗干预,包括核心足病护理、足部和踝关节锻炼、提供矫形器和鞋类,或(ii)常规护理。收集与跌倒相关的结果(跌倒次数、首次跌倒时间)和与可行性相关的结果(招募、保留、依从性、数据收集率)。次要结果包括:一般健康状况、平衡能力、活动能力、跌倒效能和踝关节力量。
对474名养老院居民进行了筛查。招募了43名(9.1%)参与者:23名进入干预组,20名进入对照组。9名(21%)参与者因健康状况下降或死亡而失访。在养老院环境中实施试验要素是可行的。35%的参与者完成了锻炼计划。48%的参与者报告“全部或大部分时间”使用了矫形器。结果测量的完成率在93%至100%之间。未报告不良事件。在九个月的随访期内,干预组每人的跌倒率为0.77次,而对照组为0.83次。
在一项干预措施的试点随机对照试验中,可以为养老院居民提供减少跌倒的足病治疗干预。尽管没有足够的能力确定有效性,但这些初步数据为进行一项更大规模的试验提供了依据,该试验将纳入全面的过程评估,以确定这种干预措施是否能显著减少这一高危人群的跌倒。
