Falls are a significant cause of morbidity and mortality in older people. There is an increased frequency of falls in older adults with cognitive impairment and dementia which may be due to impaired judgement of self capability to mobilise safely. This case control study assessed 53 Aged Care subjects aged 75+ years that were hospitalised post fall, from January 2008-December 2009, and compared these subjects' responses to those of 26 non-fallers to a standard question: 'While you are in the hospital, what would you do if you need to go to the toilet later?' This hypothetical scenario question was designed to assess judgement based on self-toileting behaviour and mobility. The study group and control group were similar in age (83.9 ± 4.7 vs. 82.0 ± 4.6 years respectively, = 0.081) but the study group had statistically lower MMSE results when compared to controls (median 23 vs. 26.5 respectively, = 0.031). Impaired judgement, defined as an unsafe/inappropriate response to the scenario question, was significantly more prevalent in the study group (fallers) compared to the control group (non-fallers) (41.5 vs. 15.4 %, = 0.020). Impaired judgement was also more common with lower MMSE scores with 80.9 % of unsafe/inappropriate responses given by participants with MMSE of ≤20. The authors suggest there may be an association between impaired judgement, evidenced by responses to a standardised question, and falls history in older subjects, particularly in those with cognitive impairment or dementia. Ultimately, this may lead to identification of people at increased risk of falls and possibly effective falls prevention strategies in this population.
跌倒是老年人发病和死亡的重要原因。认知障碍和痴呆的老年人跌倒频率增加,这可能是由于对自身安全活动能力的判断受损所致。这项病例对照研究评估了2008年1月至2009年12月期间53名75岁及以上因跌倒后住院的老年护理对象,并将这些对象对一个标准问题的回答与26名未跌倒者的回答进行了比较:“当你住院时,如果之后需要上厕所你会怎么做?”这个假设情景问题旨在评估基于自我如厕行为和行动能力的判断力。研究组和对照组年龄相似(分别为83.9±4.7岁和82.0±4.6岁,P = 0.081),但与对照组相比,研究组的简易精神状态检查表(MMSE)结果在统计学上较低(中位数分别为23和26.5,P = 0.031)。与对照组(未跌倒者)相比,研究组(跌倒者)中对情景问题做出不安全/不适当回答所定义的判断力受损更为普遍(41.5%对15.4%,P = 0.020)。判断力受损在MMSE得分较低的情况下也更常见,MMSE≤20的参与者给出的不安全/不适当回答占80.9%。作者认为,对标准化问题的回答所证明的判断力受损与老年受试者的跌倒史之间可能存在关联,特别是在那些有认知障碍或痴呆的受试者中。最终,这可能会识别出跌倒风险增加的人群,并可能制定出针对该人群有效的跌倒预防策略。
