Penicillin Allergy…Maybe Not? The Military Relevance for Penicillin Testing and De-labeling

Area of Science:

• Immunology
• Pharmacology
• Military Health

Background:

• Penicillin allergy is frequently documented but often inaccurate, affecting 8-10% of the US population.
• An incorrect penicillin allergy label increases adverse antibiotic reactions, healthcare expenses, and impacts military readiness.
• Over 90% of individuals labeled with penicillin allergy are not truly allergic.

Purpose of the Study:

• To review current literature and approaches for penicillin allergy de-labeling.
• To outline strategies for identifying and assessing penicillin allergy in military beneficiaries.
• To discuss the state of penicillin allergy testing within military allergy clinics.

Main Methods:

• A comprehensive literature review was conducted using PubMed, searching for "penicillin allergy" and "penicillin allergy testing."
• A formal discussion among military allergists at the Tri-service Military Allergy Immunology Assembly was held.
• Analysis of potential cost savings associated with penicillin de-labeling in the military population.

Main Results:

• PubMed search yielded 5,775 results for "penicillin allergy" and 484 for "penicillin allergy testing."
• Two formalized penicillin testing programs exist in military treatment facilities.
• De-labeling 90% of reported penicillin allergies could save $15-30 million annually for new recruits alone, with greater potential savings for the broader military health system.

Conclusions:

• Penicillin allergy labels negatively impact military readiness due to increased hospitalizations and medical visits.
• Penicillin de-labeling is a crucial intervention to enhance military readiness, reduce healthcare costs, and combat antibiotic resistance.
• Military allergists should lead clinic and hospital-based de-labeling efforts within antibiotic stewardship programs.
