To quantify and correlate the diagnostic error rates in radiological interpretation with the experience of the attending neuroradiologist at a tertiary academic medical centre.
The institution's Neuroradiology Quality Assurance Database of diagnostic errors was searched for misses from 2014-2020. Attendance at Head and Neck (H&N), Brain, and Paediatric Neuroradiology (PN) tumour boards (TB) as the presenting radiologist was recorded. Number of post-fellowship years of clinical practice (CPY) and frequency of TB attendance were considered separate metrics of a radiologist's experience. Radiological errors were categorised as Total, H&N, Skull Base (SKB), Brain, or PN diagnostic errors. Diagnostic error rates per attending neuroradiologist within each category were correlated with the frequency of TB participation and CPY using Spearman's rank correlation coefficients.
A total 607 examinations contained a diagnostic error. Spearman's rank correlation coefficients between Total TB participation and Total, H&N, SKB, Brain error rates were: -0.89 (p=0.0002); -0.81 (p=0.002); -0.66 (p=0.03); -0.82 (p=0.002); respectively. Spearman's rank correlation coefficients between CPY and Total, H&N, SKB, Brain and PN error rates were: 0.05 (p=0.88); 0.08 (p=0.82); 0.28 (p=0.41); -0.10 (p=0.77); -0.16 (p=0.63), respectively. Spearman's rank correlation coefficients between H&N TB and H&N, SKB error rates; and between Brain TB attendance and Brain error rates were statistically significant (p<0.05).
The present study shows a strong correlation between high TB participation rates and low diagnostic error rates. The number of years in practice did not appear to influence error rate.
量化并关联在一家三级学术医疗中心，主治神经放射科医生的经验与放射学解读中的诊断错误率。
在机构的神经放射学质量保证数据库中，搜索了 2014 年至 2020 年期间的漏诊病例。记录了主治头颈部（H&N）、脑部和儿科神经放射学（PN）肿瘤委员会（TB）时作为放射科医生的出席情况。完成住院医师培训后的年限（CPY）和 TB 出席频率被视为放射科医生经验的两个独立指标。放射学错误被分为总、H&N、颅底（SKB）、脑或 PN 诊断错误。使用 Spearman 等级相关系数，将每位主治神经放射科医生在每个类别中的诊断错误率与 TB 参与频率和 CPY 相关联。
共有 607 项检查包含诊断错误。总 TB 参与率与总、H&N、SKB、脑错误率之间的 Spearman 等级相关系数分别为：-0.89（p=0.0002）；-0.81（p=0.002）；-0.66（p=0.03）；-0.82（p=0.002）。CPY 与总、H&N、SKB、脑和 PN 错误率之间的 Spearman 等级相关系数分别为：0.05（p=0.88）；0.08（p=0.82）；0.28（p=0.41）；-0.10（p=0.77）；-0.16（p=0.63）。H&N TB 与 H&N、SKB 错误率之间，以及 Brain TB 出席率与 Brain 错误率之间的 Spearman 等级相关系数具有统计学意义（p<0.05）。
本研究表明，高 TB 参与率与低诊断错误率之间存在很强的相关性。执业年限似乎并未影响错误率。
