Aim: To audit the reporting results of a cohort of radiographers (n = 6) completing an accredited academic program in clinical reporting of computed tomography (CT) head examinations.
Methods: An audit of retrospective academic image case banks and prospective random clinical workload case banks. Both the academic test banks and clinical workload banks included a wide range of normal and abnormal cases of different levels of difficulty and pathology. Abnormalities included hemorrhage, fractures, lesions, infarctions, degeneration, and normal variants from a variety of referral sources. True positive and negative, as well as false positive and negative fractions were used to mark the reports, which were analyzed for accuracy against a reference standard. Furthermore, interobserver variability was assessed using Cohen's kappa, one-way analysis of variance, and Tukey for multiple comparisons and significance testing at 95% confidence intervals (CI).
Results: The mean accuracy score for all radiographers (n = 6) and reports (n = 3,008) was 90.7% (95% CI, 88.3%-93.0%). Mean sensitivity and specificity rates were 86.9% (95% CI, 85.8%-88.2%) and 94% (95% CI, 89.6%-98.3%), respectively. The most common errors were associated with herniation, lacunar infarctions, and subtle fractures (false negatives) and involutional changes, subtle infarctions, and ventricular dilation (false positives).
Conclusions: The results suggest appropriately trained radiographers can successfully undertake to report computed tomography head examinations to a high standard. The adoption of both academic and clinical workload image banks that reflect disease examples and the prevalence that may logically be encountered in practice offers the potential for an accurate measure of performance of radiographer's abilities.
