Incorrect classification of patient AALs is exacerbated by variations in clinicians’ knowledge about antibiotic allergies and the recording of allergies in electronic medical records.57 The prevalence of AALs in particular subgroups, such as the elderly, remains unknown; the same applies to the accuracy of AAL descriptions and their impact on antimicrobial stewardship. While models of antibiotic allergy care have been proposed8,9 and protocols for oral re-challenge in patients with “low risk allergies” successfully employed,10 the feasibility of a risk-stratified direct oral re-challenge approach remains ill defined.
