Descriptive statistics and Fisher's exact test were used to evaluate responses by practice setting.<h4>Results</h4>Sixty-six allergists responded (30% estimated response rate), with 48.4% solely practicingAllergy, asthma, and clinical immunology : official journal of the Canadian Society of Allergy and Clinical Immunology41https://www.ebi.ac.uk/biostudies/studies/S-EPMC12462252biostudies-literatureCharacterizing drug allergy management among allergists in Canada: a national survey study.PMC12462252Lee BRuiz JLee EYSong CJeimy SKrishnan SPicard MRosenfield LfalseCharacterizing drug allergy management among allergists in Canada: a national survey study.<h4>Background</h4>Unverified drug allergy labels are common and associated with significant patient harm, yet infrastructure and testing practices vary across clinical settings in Canada.<h4>Objective</h4>To characterize variability in drug allergy management among allergists in Canada and identify setting-specific barriers to drug allergy testing and desensitization.<h4>Methods</h4>We developed a peer-reviewed 40-item survey, distributed via the Canadian Society of Allergy and Clinical Immunology, to assess practice patterns, testing modalities, and perceived barriers among allergists.
