This study aimed to assess whether error review can improve radiologists' reporting performance.
Ten Consultant Radiologists reported 50 plain radiographs, in which the diagnoses were established. Eighteen of the radiographs were normal, 32 showed an abnormality. The radiologists were shown their errors and then re-reported the series of radiographs after an interval of 4-5 months. The accuracy of the reports to the established diagnoses was assessed. Chi-square test was used to calculate the difference between the viewings.
On re-reporting the radiographs, seven radiologists improved their accuracy score, two had a lower score and one radiologist showed no score difference. Mean accuracy pre-education was 82.2%, (range 78-92%) and post-education was 88%, (range 76-96%). Individually, two of the radiologists showed a statistically significant improvement post-education (P < 0.01,P < 0.05). Assessing the group as a whole, there was a trend for improvement post-education but this did not reach statistical significance. Assessing only the radiographs where errors were made on the initial viewing, for the group as a whole there was a 63% improvement post-education.
We suggest that radiologists benefit from error review, although there was not a statistically significant improvement for the series of radiographs in total. This is partly explained by the fact that some radiologists gave incorrect responses post-education that had initially been correct, thus masking the effect of the educational intervention.
本研究旨在评估错误回顾是否能提高放射科医生的报告质量。
十位放射科顾问医生对50张已确诊的普通X光片进行报告。其中18张X光片正常,32张显示异常。向放射科医生展示他们的错误,然后在4至5个月的间隔后重新报告这一系列X光片。评估报告与既定诊断的准确性。采用卡方检验计算两次阅片之间的差异。
重新报告X光片时,七位放射科医生提高了他们的准确率得分,两位得分降低,一位放射科医生得分无差异。教育前的平均准确率为82.2%(范围78 - 92%),教育后的平均准确率为88%(范围76 - 96%)。单独来看,两位放射科医生在教育后显示出统计学上的显著提高(P < 0.01,P < 0.05)。从整体评估该组,教育后有提高的趋势,但未达到统计学意义。仅评估初次阅片时出现错误的X光片,整体来看该组在教育后有63%的提高。
我们认为放射科医生从错误回顾中受益,尽管对于这一系列X光片总体而言没有统计学上的显著提高。部分原因是一些放射科医生在教育后给出了最初正确但后来错误的回答,从而掩盖了教育干预的效果。
