Background: Many barriers exist in disseminating the results of successful penicillin allergy delabels and preventing relabels. Methods: This study used electronic faxing to directly communicate the completion of successful direct oral challenges in children hospitalized or in the emergency department to outpatient pharmacies and out-of-network primary care providers. Results: This communication led to a decreased rate of the penicillin allergy label presence in pharmacy records, from 32% (36/112) to 12% (16/136) (p Conclusion: This study demonstrated that the reliable, simple, and time-efficient direct communication between independent health-care systems and pharmacies can be successful when implemented in a streamlined bundled approach.
