PURPOSE
Identifying physical frailty is useful in the context of falls and syncope assessment. The phenotype-based SHARE Frailty Instrument for Primary Care (SHARE-FI) does not measure gait speed. We evaluated the association between SHARE-FI and gait speed in a Falls' and Syncope Unit (FASU).
METHODS
We recruited a pilot sample of patients aged 50 and over attending FASU between November 2019 and March 2020. The association between gait speed and SHARE-FI was assessed with the Spearman's co-efficient (r). Logistic regression was conducted to investigate the association controlling for age, sex, body mass index, comorbidities and polypharmacy.
RESULTS
104 participants were included (34 frail) median (IQR) age 74 (68-79) years. 68 were female. There was a significant negative correlation between frailty and gait speed (r - 0.54, P < 0.001). In the multivariable model, gait speed remained independently associated with frailty (OR 0.09, 95% CI 0.02-0.52, P = 0.007).
CONCLUSIONS
SHARE-FI significantly captured gait speed in this clinical sample, adding to its validity.
目的
在评估跌倒和晕厥时，识别身体虚弱很有用。基于表型的 SHARE 初级保健衰弱工具（SHARE-FI）并不测量步态速度。我们在跌倒和晕厥单位（FASU）评估了 SHARE-FI 与步态速度之间的关联。
方法
我们招募了 2019 年 11 月至 2020 年 3 月期间在 FASU 就诊的年龄在 50 岁及以上的患者的试点样本。使用 Spearman 相关系数（r）评估步态速度与 SHARE-FI 之间的关联。进行逻辑回归以控制年龄、性别、体重指数、合并症和多药治疗来调查关联。
结果
共纳入 104 名参与者（34 名虚弱），中位（IQR）年龄 74（68-79）岁。68 名女性。衰弱与步态速度之间存在显著负相关（r-0.54，P<0.001）。在多变量模型中，步态速度仍然与衰弱独立相关（OR 0.09，95%CI 0.02-0.52，P=0.007）。
结论
在这个临床样本中，SHARE-FI 显著捕捉到了步态速度，增加了其有效性。
