To evaluate the impact of an intervention to reduce fall hazards in the homes of older people.
The intervention was administered to the 570 subjects in the experimental arm of a randomized controlled trial, with follow-up of subjects for 1 year.
Community-based seniors living in Perth, Australia.
People age 70 and older.
Registered nurses delivered the intervention. It consisted of a home hazard assessment, an educational strategy on general fall hazard reduction and ways to reduce identified home hazards, and the free installation of safety devices: grab rails, nonslip stripping on steps, and double-sided tape for floor rugs and mats. All intervention subjects received the home hazard assessment, and 96% received the educational strategy. Grab rails were installed in 77% of homes, rugs were stabilized in 8%, and nonslip step stripping was installed in 36%.
Hazard prevalence was assessed at baseline in all homes and 11 months later in a random sample of 51 homes. Action taken in response to the intervention was assessed by a self-completed postal questionnaire completed 11 months after the intervention.
All homes had at least one fall hazard. The most prevalent were floor rugs and mats (mean of 14 per home), stepovers (Stepovers are structural changes to the height of the floor that were designed to be stepped over rather than stepped upon, for example, the lip of a shower or a bath side.) (mean of seven per home), steps (mean of four per home), and trailing cords (mean of two per home). The intervention was associated with a small but significant reduction in four of the five most prevalent hazards. The mean number of unsafe rugs and mats was reduced by 1.57 per house (95% confidence interval (CI) = 0.91-2.24); the mean number of unsafe steps was reduced by 0.61 per house (95% CI = 0.28-0.94); the mean number of rooms with trailing cords was reduced by 0.43 per house (95% CI = 0.10-0.76); and the mean number of unsafe chairs was reduced by 0.10 per house (95% CI = 0.02-0.18). Safety devices were installed in 81.9% of homes. Advice on modifying specific hazards identified on the home hazard assessment resulted in over 50% of subjects removing hazards of floor rugs and mats, trailing cords, and obstacles. The general education message prompted less activity to reduce these hazards than did the advice on identified hazards.
Fall hazards are ubiquitous in the homes of older people. The intervention resulted in a small reduction in the mean number of hazards per house, with many study subjects taking action but removing only a few hazards. The impact of the intervention in achieving self-reported action to reduce hazards was high.
评估一项旨在减少老年人家庭中跌倒风险因素的干预措施的效果。
在一项随机对照试验的实验组中,对570名受试者实施该干预措施,并对受试者进行为期1年的随访。
澳大利亚珀斯的社区老年人。
70岁及以上的人群。
由注册护士实施干预。干预内容包括家庭风险评估、关于一般跌倒风险降低及减少已识别出的家庭风险因素方法的教育策略,以及免费安装安全装置:扶手、台阶上的防滑条、用于地毯和垫子的双面胶带。所有干预组受试者均接受了家庭风险评估,96%的受试者接受了教育策略。77%的家庭安装了扶手,8%的家庭固定了地毯,36%的家庭安装了台阶防滑条。
在所有家庭的基线时评估风险因素的发生率,并在11个月后对51个家庭的随机样本进行评估。通过干预11个月后自我填写的邮政问卷评估针对干预措施所采取的行动。
所有家庭至少存在一种跌倒风险因素。最常见的是地毯和垫子(每户平均14个)、跨槛(跨槛是指地板高度的结构性变化,设计目的是供人跨过而非踩踏,例如淋浴间或浴缸边缘)(每户平均7个)、台阶(每户平均4个)和拖曳的电线(每户平均2根)。该干预措施与五种最常见风险因素中的四种的小幅但显著减少相关。每户不安全地毯和垫子的平均数量减少了1.57个(95%置信区间(CI)=0.91 - 2.24);每户不安全台阶的平均数量减少了0.61个(95% CI = 0.28 - 0.94);有拖曳电线的房间平均数量每户减少了0.43个(95% CI = 0.10 - 0.76);每户不安全椅子的平均数量减少了0.10个(95% CI = 0.0 .18)。81.9%的家庭安装了安全装置。关于修改家庭风险评估中识别出的特定风险因素的建议,使得超过50%的受试者消除了地毯和垫子、拖曳电线及障碍物等风险因素。与针对已识别风险因素的建议相比,一般教育信息促使减少这些风险因素的行动较少。
跌倒风险因素在老年人家庭中普遍存在。该干预措施使每户风险因素的平均数量略有减少,许多研究受试者采取了行动,但仅消除了少数风险因素。该干预措施在促使自我报告采取行动减少风险因素方面的效果显著。
