At a Canadian ambulatory hospital, a quasi-experimental quality improvement initiative evaluated penicillin-allergy education modules using pre–post surveys. Among 61 clinicians, Module 1 was not associated with change in penicillin allergy label-clinical impact knowledge. Modules 2 and 3 improved allergy-history, severity-assessment, and prophylaxis-prescribing preparedness ( P < .01). Acceptability was high: documentation tool 92%, algorithm 88%.
