Background: The prevalence of hypersensitivity reactions to radiological contrast media (RCM) is increasing due to the greater performance of diagnostic and therapeutic tests that require RCMs.
Objective: We carried out a year-long real-life observational study to prospectively evaluate the patients referred to the Allergy Service from Primary Care, Emergency Room, and other Services with suspected moderate to severe RCM hypersensitivity.
Methods: To study the costs of RCM hypersensitivity evaluation, we systematically recorded direct and indirect costs.
Results: Sixty-nine patients with previous reactions to RCM were evaluated in the Allergy Service from June 1st, 2017, to May 31st, 2018. Total direct health care costs were € 10715.84, with a mean cost per patient of € 155.30 ± 77.08. Specifically, direct non-health 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 € 18812.11, which means a mean cost of € 272.64 ± 164.77.
Conclusions: Our study reflects that the costs of an elective evaluation of hypersensitivity to RCM are low. This fact reaffirms that correct and safe management of these patients could be cost-effective, so our efforts should be directed to implement the necessary logistics.
