Abstract

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.

摘要

目的

研究在线审核和反馈对胎儿四腔心切面图像质量的影响。

方法

超声医师上传 10 次连续筛查检查的四腔心切面图，然后在 3 个月后再次上传。他们被随机分为两组，一组（A 组）接受反馈，另一组（B 组）不接受反馈。主要结局指标是比较两组中有无反馈时，第一组和第二组图像平均评分和图像不足百分比的差异。

结果

共有 258 名超声医师完成了试验（A 组 122 名，B 组 136 名），共审核了 5160 张图像。两组的平均评分均有所提高。A 组从 17.0 提高到 18.5（p<0.0001），B 组从 17.6 提高到 18.3（p<0.0001）。A 组的改善程度大于 B 组（1.5 比 0.7，p=0.0007）。两组的图像不足百分比均有所下降。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%比 5%，p=0.007）。
