Background: The prevalence of hypersensitivity reactions to radiological contrast media (RCM) is increasing owing to the improved performance of diagnostic and therapeutic tests that require RCMs.
Objective: We carried out a year-long real-life observational study to prospectively evaluate patients referred to the allergy department from primary care, the emergency department, and other specialties with suspected moderate-to-severe RCM hypersensitivity reactions.
Methods: To study the costs of evaluating RCM hypersensitivity reactions, we systematically recorded direct and indirect costs.
Results: Sixty-nine patients with previous reactions to RCM were evaluated in the allergy department from June 1, 2017, to May 31, 2018.Total direct health care costs were €10 715.84, with a mean (SD) cost per patient of €155.30 (77.08). Specifically, direct non–health care costs reached €1605.42 (mean, €23.27 [41.14]), and indirect costs were €6490.85 (mean, €94.07 [110.61]). In summary, the total cost was €18 812.11, that is, a mean cost of €272.64 (164.77).
Conclusions: Our study shows that the costs of an elective evaluation of hypersensitivity reactions to RCM are low, thus confirming that correct and safe management of affected patients are cost-effective. Therefore, our efforts should be directed toward ensuring the necessary logistics.
