A Prospective Study of Costs Associated With the Evaluation of Allergic Reactions to Radiological Contrast Media.

Background And Objective: 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.

A Prospective Study of Costs Associated with the Evaluation of β-Lactam Allergy in Children.

Objective: To evaluate the costs associated with evaluation of β-lactam allergy in children labeled as allergic.

Study Design: We performed a prospective year-long real life observational study designed to evaluate all pediatric patients with suspected β-lactam allergy who consulted for allergy evaluation. Direct and indirect costs were systematically recorded.
