Objectives我们的目的是研究在线审计和反馈对胎儿四腔视图图像quality.Methods的影响超声医师上传一组四腔视图从10个连续的筛选检查和第二组3个月后。他们被随机分为两组，A组接受反馈，B组不接受反馈。主要结果是图像的平均分数和第一组和第二组之间的图像不足的百分比的差异，比较组和没有feedback.Results有258超声谁完成了试验（A组：122;组B：136），和5160图像进行了审计。在两组中，平均得分均增加。A组从17.0升至18.5（p < 0.0001），B组从17.6升至18.3（p < 0.0001）。A组的改善大于B组（1.5 vs 0.7，p = 0.0007）。两组中不充分图像的平均百分比均下降。A组从32%降至19%（p < 0.0001），B组从26%降至21%（p = 0.012）。A组的下降幅度大于B组（13%vs5%，p = 0.007）。结论在线审计后图像质量有所改善，反馈后图像质量的改善幅度略大。(C)2013年约翰威利父子有限公司
Objectives We aimed to study the impact of online audit and feedback on fetal four-chamber view image quality.Methods Ultrasonographers uploaded a set of four-chamber views from 10 consecutive screening examinations and a second set 3 months later. They were randomised to receive (group A) or not (group B) a feedback for their first set. The primary outcome was the difference in image mean score and in percentage of inadequate images between the first set and the second set, comparing the groups with and without feedback.Results There were 258 ultrasonographers who completed the trial (group A: 122; group B: 136), and 5160 images were audited. In both groups, the mean score increased. In group A, it rose from 17.0 to 18.5 (p < 0.0001), and in group, B from 17.6 to 18.3 (p < 0.0001). The improvement was greater in group A than in group B (1.5 vs 0.7, p = 0.0007). The mean percentage of inadequate images decreased in both groups. In group A, it dropped from 32% to 19% (p < 0.0001), and in group B, from 26% to 21% (p = 0.012). The decrease was greater in group A than in group B (13% vs 5%, p = 0.007).Conclusions Image quality improved following online audit, the improvement being slightly greater with feedback.
