Drug Allergy Alert System in a Spanish University Hospital: Description and Dynamics of Use.

Introduction: The drug allergy alert system reduces the frequency of adverse drug events, although it is subjected to collateral effects, since 80-90% of alerts are not real, and a large percentage of alerts are overridden (46.2-96.2%).

Analysis of the Safety of Drug Allergy Workups in a Spanish University Hospital: Drug Characteristics, Type of Reaction, and Patients' Age at the Initial Assessment.

Introduction: The drug provocation test (DPT) is the gold standard for the drug allergy workup; however, it is not free from severe adverse reactions. Our aim was to obtain robust data that predict a reaction during or after the DPT at the first contact with the patient in the allergy outpatient clinic.

Methods: The population of this cross-sectional study comprised all patients undergoing a drug allergy workup (clinical assessment, specific IgE, or skin tests, or DPT) at University Hospital Fundacion Alcorcon in 2016.
