摘要
目的 比较跌倒风险自评表(FRQ)与Morse跌倒评估量表(MFS)在绝经后骨质疏松症(PMOP)人群中的应用价值,为该人群跌倒风险评估工具的选择提供参考.方法 采用便利抽样法纳入2020年9月-2022年1月于蚌埠医科大学第一附属医院体检或就诊的193例PMOP患者作为研究对象,使用FRQ和MFS进行跌倒风险评估.根据随访期间是否跌倒分为跌倒组(32例)和未跌倒组(161例),通过ROC曲线、灵敏度、特异度及Bayes判别分析评价量表.结果 跌倒组FRQ和MFS量表得分均高于未跌倒组,差异有统计学意义(P＜0.001);FRQ、MFS的AUC分别为0.865和0.737,差异有统计学意义(P=0.003);FRQ、MFS临界值分别为4分和40分时,约登指数分别为0.546和0.360,此时灵敏度分别为0.844和0.813,特异度分别为0.702和0.547,阳性预测值、阴性预测值、阳性似然比、阴性似然比分别为0.360、0.958、2.830、0.223和0.263、0.936、1.792、0.343,交叉检验准确率分别为72.5％和60.6％.结论 FRQ与MFS均能有效预测PMOP人群的跌倒风险.与MFS相比,FRQ预测价值更高.
Abstract
Objective To compare the value of the self-rated fall risk questionnaire(FRQ)and the Morse fall scale(MFS)in assessing fall risk in postmenopausal osteoporosis(PMOP),and to inform the selection of fall risk assessment tools for this population.Methods A total of 193 postmenopausal women with a confirmed diagnosis of osteoporosis were selected from the First Affiliated Hospital of Bengbu Medical University from September 2020 to January 2022 by conven-ience sampling method,and were invited to attend a survey of their fall risk assessed by the FRQ and MFS and follow-up on falls.The group was divided into a fall group(n=32)and a non-fall group(n=161)according to whether they fell or not during the follow-up period,and the scale was evaluated by means of ROC curve,sensitivity,specificity and Bayes discriminant analysis.Results The scores of both scales in the fall group were higher than those in the non-fall group,and the difference was statistically significant(P＜0.001);the AUC of the FRQ and MFS were 0.865 and 0.737,re-spectively,and the difference was statistically significant(P=0.003);the Youden's index was 0.546 and 0.360 at crit-ical values of 4 and 40 for the FRQ and MFS,respectively,when the sensitivity was 0.844 and 0.813,and specificity was 0.702 and 0.547,respectively.The positive predictive value,negative predictive value,positive likelihood ratio and negative likelihood ratio were 0.360,0.958,2.830,0.223 and 0.263,0.936,1.792,0.343,respectively.The cross-check accuracy of the FRQ and MFS was 72.5％and 60.6％,respectively.Conclusion Both FRQ and MFS can effec-tively predict the risk of falls in postmenopausal osteoporosis,while,FRQ shows a higher predictive value compared to MFS.
