To evaluate handgrip strength (HGS) as a diagnostic tool for frailty risk in elderly patients with asthma, as well as to investigate the prevalence of frailty in this population.
This was a cross-sectional study including 96 patients ≥ 60 years of age diagnosed with moderate to severe asthma and treated at a tertiary referral center in Brazil. We measured HGS using a calibrated hydraulic hand dynamometer. We used a frailty scale and the AUC to assess the diagnostic accuracy of the HGS test.
The median age of participants was 67 years. Most (78%) were women and non-White (91%) of low socioeconomic status. HGS identified those at risk for frailty, with an AUC of 71.6% (61.5-80.4%; p < 0.002), as well as a sensitivity of 73.58% and a specificity of 67.53%, on the basis of a cutoff of ≤ 19 kgf.
HGS appears to be a simple, reliable tool for clinicians to determine frailty risk in older asthma patients in a point-of-care setting.
评估握力（HGS）作为诊断老年哮喘患者衰弱风险的工具，并调查该人群中衰弱的患病率。
这是一项横断面研究，纳入了 96 名年龄≥60 岁、在巴西一家三级转诊中心诊断为中重度哮喘并接受治疗的患者。我们使用校准的液压测力计测量 HGS。我们使用衰弱量表和 AUC 来评估 HGS 测试的诊断准确性。
参与者的中位年龄为 67 岁。大多数（78%）为女性，非白种人（91%）且社会经济地位较低。HGS 可识别衰弱风险患者，AUC 为 71.6%（61.5-80.4%；p<0.002），截断值≤19kgf 时，灵敏度为 73.58%，特异性为 67.53%。
HGS 似乎是一种简单、可靠的工具，可让临床医生在即时护理环境中确定老年哮喘患者的衰弱风险。
