摘要:
目的 检验康复分级诊疗评定量表A、B版的信效度及截断值,并确定更适用的版本。 方法 2022年4月在深圳市四家康复机构开展研究,使用Cronbach′s α系数、组内相关系数(ICC)、Kaiser-Meyer-Olkin(KMO)、Bartlett球形检验、Spearman相关系数和ROC曲线对量表进行检验。 结果 A、B版量表的Cronbach′s α系数分别为0.740和0.694,ICC>0.75。A、B版量表的KMO值分别为0.659和0.660,Bartlett球形检验P<0.01。A、B版量表与美国国立卫生院卒中量表(NIHSS)相关性>0.75,而与改良Rankin量表(mRS)相关性为-0.101和-0.063。NIHSS>20分对应A、B版量表疾病项得分为2.5分和7.5分,AUC分别为0.775(95% CI:0.677~0.855)和0.840(95% CI:0.750~0.908)。A版量表功能项对应龙氏日常生活能力评定量表(LS)床上人和社会人得分为7.5分和5分,AUC分别为0.541(95% CI:0.435~0.645)和0.575(95% CI:0.469~0.677);B版功能项对应LS量表床上人和社会人得分为10分和5分,AUC分别为0.500(95% CI:0.395~0.606)和0.555(95% CI:0.448~0.658)。 结论 康复分级诊疗评定量表A、B用于脑卒中患者均具有良好的信度和效度,但功能项评定内容仍需调整。分级诊疗评定量表B更适用于评定脑卒中患者转诊需求。 -

Abstract:Objective To evaluate the reliability, validity and cut-off points of version A and B of the hierarchical diagnosis and treatment rating scale, and to determine a more applicable version. Methods The study was conducted in four rehabilitation facilities in Shenzhen in April 2022, and the scales were tested using Cronbach′s α coefficient, interclass correlotion coefficient (ICC), Kaiser-Meyer-Olkin (KMO) and Bartlett's spherical test, Spearman correlation coefficient and ROC curves. Results The Cronbach's α coefficients for version A and B were 0.740 and 0.694, respectively, with ICC greater than 0.75. The KMO values for version A and B were 0.659 and 0.660, respectively, with Bartlett spherical test P < 0.01. The correlation between the scale (version A and B) and the National Institute of Health Stroke Scale (NIHSS) was greater than 0.75, while the correlation between the scale (version A and B) and modified Rankin scale (mRS) were -0.101 and -0.063 respectively. NIHSS>20 points corresponded to disease item scores of 2.5 and 7.5 points in the A and B version of the scale, with AUCs=0.775 (95% CI: 0.677-0.855) and 0.840 (95% CI: 0.750 -0.908). The functional items of version A corresponded to the scores of 7.5 and 5 for bedridden group and community group of Longshi scale (LS), with AUC=0.541 (95% CI: 0.435-0.645) and 0.575 (95% CI: 0.469-0.677); The functional items in version B corresponded to the scores of 10 and 5 for bedridden group and community group of LS, with AUCs=0.500 (95% CI: 0.395-0.606) and 0.555 (95% CI: 0.448-0.658). Conclusion Both hierarchical diagnosis and treatment rating scale A and B have good reliability and validity for application with stroke patients. However, the functional components of the scale need further adjustment. Items in version B are more appropriate for assessing patients' rehabilitation needs and referral directions. -
