Our goal was to analyze those factors contributing to the error rate in the interpretation of abdominal CT scans at an academic medical center.
From a total of 694 consecutive patients (329 male, 365 female), we evaluated the error rates of interpreting abdominal CT studies. The average patient age was 54 years. All abdominal CT studies were reviewed by three to five CT faculty radiologists on the morning after the studies were performed. The error rate was correlated with reader variability, the number of cases read per day, the presence of a resident, inpatient versus outpatient, organ systems, etc. The chi 2-test was used for statistical analysis.
A total of 56 errors were found in the reports of 53 patients (overall error rate = 7.6%). Of these errors, 19 were judged to be clinically significant and 7 affected patient management. A statistically significant difference in error rates was noted among the five faculty radiologists (3.6-16.1%, p = 0.00062). No significant correlates between error rates and any of the other variables could be established.
The primary determinant of error rates in body CT is the skill of the interpreting radiologist.
我们的目标是分析在一所学术性医学中心腹部CT扫描解读中导致错误率的那些因素。
从总共694例连续患者（329例男性，365例女性）中，我们评估了腹部CT研究解读的错误率。患者平均年龄为54岁。所有腹部CT研究在检查完成后的次日上午由三至五名CT专业放射科医生进行复查。错误率与阅片者差异、每日阅片病例数、住院医师的存在、住院患者与门诊患者、器官系统等相关。采用卡方检验进行统计分析。
在53例患者的报告中总共发现56处错误（总体错误率 = 7.6%）。在这些错误中，19处被判定具有临床意义，7处影响了患者的治疗管理。五名专业放射科医生之间的错误率存在统计学显著差异（3.6 - 16.1%，p = 0.00062）。错误率与任何其他变量之间均未发现显著相关性。
身体CT错误率的主要决定因素是解读放射科医生的技能。
