Proactive risk stratification and low-risk penicillin allergy delabeling by an antimicrobial stewardship pharmacist

Abstract

Abstract Penicillin (PCN) allergy delabeling is an important component of antimicrobial stewardship; however, widespread implementation has lagged. We found that most patients had low-risk PCN allergy histories eligible for delabeling without skin testing. Pharmacist-led risk stratification and drug challenge expanded access to delabeling independently from an Allergy/Immunology service.
