PURPOSE: To determine the association between workload and diagnostic errors on clinical CT scans. METHOD: of > 100% indicates relative work overload in terms of reported examinations on an individual radiologist's basis. RESULTS: on the days the diagnostic errors were made was on average 121% (95% confidence interval: 106% to 136%), which was significantly higher than 100% (P = 0.008). There was no significant upward monotonic trend in diagnostic errors over the course of the day (Mann-Kendall tau of 0.005, P = 1.000), and there were no other notable temporal trends either. CONCLUSIONS: Radiologists appear to have a relative work overload when they make a diagnostic error on CT. Diagnostic errors occurred throughout the entire day, without any increase towards the end of the day.
