Abstract
Background: Falls are a significant health problem for seniors, often indicating increasing mobility impairment and risk of injury. Although necessary for the identification of seniors at risk, only few validated German questionnaires on falls risk exist.
Objective: To validate the German Fall Risk Check (FRC) in independently living, community-dwelling older people against objective measurement of standing and walking balance as assessed by the Short Physical Performance Battery (SPPB).
Material and methods: In a larger randomized controlled trial, evaluating home emergency call systems, we recruited 190 seniors in Hamburg, Germany, to fill in the FRC and pass a comprehensive geriatric assessment. The performance of FRC as a diagnostic test is described by typical measures, such as sensitivity (SN), specificity (SP), predictive values, positive/negative likelihood ratios (LR+/LR-), and area under the curve (AUC) in receiver operator characteristic (ROC) curve analysis, each with corresponding 95% confidence intervals (CI).
Results: In total, 190 seniors with an average age 80.5 years (± 5.5 years), 75.3% women could be analyzed. The sample showed advanced comorbidity and concerns about falling in about one third, and mobility and cognitive impairment in about one half. We calculated: SN 0.679 (95% CI 0.571-0.771); SP 0.743 (95% CI 0.654-0.816); LR+ 2.643 (95% CI 1.858-3.761); and LR- 0.432 (95% CI 0.309-0.604). The unadjusted AUC was 0.711 (95% CI 0.635-0.787), adjusted for sex and age 0.753 (95% CI 0.683-0.824).
Conclusion: The FRC appears to be a valid questionnaire, identifying impaired balance in community-dwelling seniors.
背景：跌倒对老年人来说是一个重要的健康问题，通常表明活动能力受损和受伤的风险增加。虽然有必要识别处于危险中的老年人，但只有少数有效的德国跌倒风险问卷存在。目的：验证德国跌倒风险检查（FRC）在独立生活，社区居住的老年人站立和行走平衡的客观测量，通过短物理性能电池（SPPB）评估。材料和方法：在一个更大的随机对照试验中，评估家庭紧急呼叫系统，我们在德国汉堡招募了190名老年人填写FRC并通过全面的老年评估。FRC作为诊断试验的性能是通过典型的测量来描述的，如敏感性（SN）、特异性（SP）、预测值、阳性/阴性似然比（LR+/LR-）和曲线下面积（AUC），每一个都有相应的95%置信区间（CI）。结果：共分析老年人190例，平均年龄80.5岁（± 5.5岁），其中女性占75.3%。样本显示，大约三分之一的人有严重的合并症，担心摔倒，大约一半的人有行动能力和认知障碍。我们计算出：SN为0.679 (95% CI 0.571-0.771)；Sp = 0.743 (95% ci = 0.654-0.816)；Lr + 2.643 (95% ci 1.858-3.761)；LR- 0.432 （95% CI 0.309-0.604）。未经校正的AUC为0.711 (95% CI 0.635-0.787)，经性别和年龄校正后为0.753 （95% CI 0.683-0.824）。结论：FRC是一份有效的问卷，可以识别社区居住老年人的平衡障碍。
期刊介绍：
The fact that more and more people are becoming older and are having a significant influence on our society is due to intensive geriatric research and geriatric medicine in the past and present. The Zeitschrift für Gerontologie und Geriatrie has contributed to this area for many years by informing a broad spectrum of interested readers about various developments in gerontology research. Special issues focus on all questions concerning gerontology, biology and basic research of aging, geriatric research, psychology and sociology as well as practical aspects of geriatric care.
Target group: Geriatricians, social gerontologists, geriatric psychologists, geriatric psychiatrists, nurses/caregivers, nurse researchers, biogerontologists in geriatric wards/clinics, gerontological institutes, and institutions of teaching and further or continuing education.
