Summary: | 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.
•Strong correlation between high total TB participation & low total error rates.•Strong correlation between high H&N TB rates & low H&N, SkB error rates.•Strong correlation between high Brain TB & low Brain error rates.•No significant correlation between years of clinical practice and error rates. |
