New Avenues for Antimicrobial Stewardship: The Case for Penicillin Skin Testing by Pharmacists.

It is well-appreciated that patients with documented penicillin allergies often receive broader-spectrum antibiotics. This practice has been associated with increased antimicrobial resistance and cost. In recent years, considerable efforts have been made to spread awareness on the implications of self-reported penicillin allergies. The use of penicillin skin testing to evaluate for true allergies has been strongly recommended by major organizations for decades. However, testing remains underutilized. Current literature has suggested various models of incorporating penicillin allergy screening and testing by different healthcare practitioners (ie, physicians, allergists, nurses, pharmacists). We suggest broader adoption for the role of pharmacists in the provision of penicillin skin testing. This would help expand the service and maximize the potential benefits of penicillin skin testing.
