Penicillin allergy skin testing as an antibiotic stewardship intervention reduces alternative antibiotic exposures in hematopoietic stem cell transplant recipients

Abstract

Antibiotic allergy de‐labeling using penicillin allergy skin testing (PAST) can reduce the use and cost of alternative, non‐β‐lactam antibiotics in general inpatient populations. This strategy s role in hematopoietic stem cell transplant (HSCT) recipients is unclear.
