Abstract

BACKGROUND: The negative effect of the penicillin allergy label on antibiotic use and patient outcomes has brought to light the need for thorough penicillin allergy assessments and heightened practitioner education. OBJECTIVE: To evaluate practitioner knowledge of penicillin allergy and the clinical approach to the patients with penicillin allergy. METHODS: An electronic survey was distributed to attending physicians, residents, pharmacists, nurse practitioners, and physician assistants practicing adult inpatient medicine at 2 community-based teaching hospitals from February to April 2016. RESULTS: A total of 276 (39%) of 716 practitioners completed surveys were analyzed. Most respondents were attending physicians (45%) with more than 10 years of experience (53%). Approximately half of the respondents indicated that they were unfamiliar with the rate of cross-reactivity between penicillin and cephalosporin (46%), carbapenem (42%), and monobactam (48%) antibiotics. When evaluating the role of penicillin skin testing and temporary induction of drug tolerance in the case vignettes, only 41% and 19% of respondents appropriately considered these options as the leading antibiotic management plan, respectively. Despite acknowledging the need for allergy/immunology consultation in clinical scenarios, 86% of respondents indicated that they never consult an allergist or immunologist or do so only once per year. Overall, pharmacists had a better understanding of the natural history of penicillin allergy and antibiotic cross-reactivity (P < .05). CONCLUSION: There is an overall limited understanding of the management of patients with a history of penicillin allergy in the hospital setting, where collaborative efforts between allergy and nonallergy health care practitioners are sparse. The expansion of a multidisciplinary approach may optimize antimicrobial prescribing in this subset of patients.
