Long-term impacts of antibiotic allergy testing on patient perceptions and antibiotic utilization

Abstract

Objectives: To define the long-term impacts of antibiotic allergy testing (AAT) on patient allergy perception and antibiotic utilization. Methods: Patients were identified from a prospective AAT database as having completed testing during a 15 month period beginning January 2017. Patients were contacted for a follow-up survey at least 12 months post-AAT. For those contacted, baseline demographics, antibiotic allergy label (AAL) history, age-adjusted Charlson comorbidity index, infection history, antibiotic de-labelling (≥1 AAL removed following AAT) and antibiotic usage for 12 months prior to testing (pre-AAT) and 12 months following testing (post-AAT) were recorded for each patient.
