To test the reliability of the Outcome Measures in Rheumatology Giant cell arteritis (GCA) Ultrasonography Score (OGUS) and other composite scores in a patient-based exercise involving experts and non-experts in vascular ultrasonography.
Six GCA patients were scanned twice (two rounds separated ≥3 hours) by 12 experts and 12 non-experts. Non-experts received 90 min of theoretical and 240 min of practical training between rounds 1 and 2. Ultrasonography was conducted on temporal arteries (common superficial, frontal and parietal branches) and axillary arteries bilaterally to calculate the OGUS, the Southend score and the Halo count. Inter-reader and intra-reader reliability were assessed by intraclass correlation coefficient (ICC).
Mean age of GCA patients was 78±5.1 years, 2 (33.3%) were women, and all were in clinical remission. Expert inter-reader ICC of the OGUS was 0.60 in both rounds, 0.40 in round 1 and 0.51 in round 2 for the Southend score and 0.45 and 0.52, respectively, for the Halo count. Median ICCs for intra-reader reliability were 0.86, 0.73 and 0.65 for the OGUS, Southend score and Halo count, respectively.For non-experts, inter-reader ICCs in round 1 were 0.20 for the OGUS, 0.20 for a normalised Southend score (=score divided by available segments) and 0.35 for a normalised Halo count. After training, inter-reader reliability ICCs improved to 0.52, 0.29 and 0.54, respectively.
Inter-reader reliability was fair to moderate, and intra-reader reliability was good for OGUS, Southend score and Halo count among experts. Inter-reader reliability of non-experts in vascular ultrasonography improved after the training.
在一项涉及血管超声专家和非专家的患者实践活动中，检验风湿病巨细胞动脉炎（GCA）超声检查结果测量评分（OGUS）及其他综合评分的可靠性。
12名专家和12名非专家对6例GCA患者进行两次扫描（两轮扫描间隔≥3小时）。非专家在第一轮和第二轮扫描之间接受了90分钟的理论培训和240分钟的实践培训。对双侧颞动脉（常见浅表、额支和顶支）和腋动脉进行超声检查，以计算OGUS、绍森德评分和晕环计数。通过组内相关系数（ICC）评估阅片者间和阅片者内的可靠性。
GCA患者的平均年龄为78±5.1岁，2例（33.3%）为女性，所有患者均处于临床缓解期。OGUS阅片者间的专家ICC在两轮中均为0.60，绍森德评分在第一轮为0.40，第二轮为0.51，晕环计数分别为0.45和0.52。阅片者内可靠性的中位数ICC，OGUS为0.86，绍森德评分为0.73，晕环计数为0.65。对于非专家，第一轮阅片者间的ICC，OGUS为0.20，标准化绍森德评分（=评分除以可用节段数）为0.20，标准化晕环计数为0.35。培训后，阅片者间可靠性的ICC分别提高到0.52、0.29和0.54。
阅片者间可靠性为中等，阅片者内可靠性对于专家而言，OGUS、绍森德评分和晕环计数良好。血管超声检查中非专家的阅片者间可靠性在培训后有所提高。
