The results of a recent study presented at the Annual meeting of the of the American College of Asthma, Allergy and Immunology indicated that in 90% of cases, patients who were recorded as penicillin-allergic on their medical records subsequently tested negative for penicillin allergy.

A large number of these patients had high-risk conditions such as diabetes, HIV, malignancy or immunosuppression. The negative testing enabled a significant reduction in the use of vancomycin, clindamycin, aztreonam, carbapenems and fluoroquinolones.

Full results of the study will be published in the Journal of Allergy & Clinical Immunology: In Practice in January 2017.
