ObjectiveTo determine the frequency, nature (using standardized coding taxonomy), and temporal trends of patient complaints about the radiological service provided in a European tertiary care center.MethodsThis retrospective study included all written patient complaints received by the department of radiology of a European tertiary care center within a 9-year period.ResultsA total of 94 written patient complaints were included. Overall complaint frequency was 14.4 per 100,000 radiological procedures. Complaint frequencies per 100,000 procedures were 103.7 for interventional radiology, 13.9 for MRI, 6.9 for ultrasonography, 6.5 for CT, 4.5 for fluoroscopy, and 1.2 for conventional radiography. Interventional radiology received significantly more complaints than all other radiological procedures (p < 0.001), and cross-sectional imaging (CT, MRI, and ultrasonography) received significantly more complaints than conventional radiography (p < 0.001). Fifty-three (56.4%) complaints belonged to the clinical domain, 22 (23.4%) to the relationships domain, and 19 (20.2%) to the management domain. Quality (34.0%), safety (22.3%), timing and access (18.1%), and communication (18.1%) constituted almost all complaint categories. Patient journey (19.1%), delays (18.1%), communication breakdown (16.0%), errors in diagnosis (11.7%), quality of care (9.6%), treatment (6.4%), and staff attitudes (2.1%) constituted almost all complaint subcategories. Annual frequency of complaints decreased over time (Mann-Kendall tau = − 0.429), although not significantly (p = 0.174).ConclusionWritten patient complaints directed to a department of radiology at a European tertiary care center are relatively few in number and have not shown a temporal increase. Knowledge of sources of patient dissatisfaction may help to reduce the number of patient complaints and improve patient care.Key Points• Approximately 14.4 written patient complaints per 100,000 radiological procedures are filed in a European tertiary care center, and they have not increased over a 9-year period.• Written patient complaints most frequently involve interventional radiology, and the main complaint categories are quality (34.0%), safety (22.3%), timing and access (18.1%), and communication (18.1%).• Knowledge of the nature of and circumstances under which patient complaints arise may reduce their number and improve patient care.
