1新加坡成人慢性呼吸系统疾病患者6分钟步行距离的最小临床重要差异值研究(英文)显示文摘目的:6 min步行距离(6MWD)是临床上常见的功能性运动能力测试,特别是对于慢性呼吸系统疾病患者。一些文献记载了关于白种人的6MWD的最小临床重要差异(MCID),但对亚洲人群的相关信息未见记载。本研究旨在建立亚洲成人慢性呼吸道疾病患者6MWD的最小临床重要差异。方法:采用'锚定'法和'分布'法对新加坡中央医院肺康复计划登记处的资料进行了分析。'锚定'法收集确诊为慢性呼吸道疾病的患者50例,其中男38例,女12例;平均年龄(64.2±12.3)岁,通过电话采访及使用整体变化评估量表(GROC)评价患者肺康复计划后的自觉改善程度,再将患者在肺康复计划中6MWD的改变数值与相对应的患者自觉改善程度进行比较,这种关系用操作特征曲线(ROC)统计表示。通过'分布'法确定6MWD的MCID,从门诊和住院的肺康复计划(PRP)参与者中检索医疗记录136例,其中男103例,女33例;平均年龄(60.1±14.1)岁。结果 :ROC曲线表明6MWD出现临床显著性变化的最佳临界值为17.4 m,其对应的敏感性为79.4%,特异性为81.3%,阳性似然比为4.23。由'分布'法确定6MWD的最小临床重要差异值为18.6 m。结论:18.6 m为新加坡华人6MWD的最小临床重要差异的估计值。Meredith T L YEUNG Alan W P WONG Katherine S L HUANG Alice Y M JONES 2015康复学报2015,25,1:3
