Abstract
Background: Patients who undergo treatment may suffer preventable medical errors. Some of these errors are due to diagnostic imaging procedures.
Purpose: To compare the frequency of diagnostic errors in different age groups in an urban European population.
Material and Methods: A total of 19 129 reported radiologic examinations were included. During a 6-month period, the analyzed age groups were: children (aged 0–9 years), adults (40–49 years), and elderly (86–95 years).
Results: The frequency of radiologic examinations per year was 0.3 in children, 0.6 in adults, and 1.1 in elderly. Significant errors were significantly more frequent in the elderly (1.7%) and children (1.4%) compared with adults (0.8%). There were 60 false-positive reports and 232 false-negative reports. Most errors were made by staff radiologists after hours when they reported on examinations outside their area of expertise.
Conclusion: Diagnostic errors are more frequent in children and the elderly compared with middle-aged adults.
