Process for penicillin allergy de-labeling in the electronic medical record by (a) changing the status of the current penicillin allergy to “resolved”, then (b) entering a placeholder for a tolerated penicillin oral challenge (or for a negative penicillin allergy skin test, as applicable). Panel (c) shows the display of “all” allergies for the patient, both active and inactive (e.g., resolved). The patient’s demographic bar in the electronic medical record is set to display only “active” allergies by default. In the “active” display, the penicillin oral challenge label would remain, but the penicillin allergy label would no longer be seen.
