Addressing the epidemic of antibiotic "allergy" over-diagnosis

Objective:
An epidemic of antibiotic allergy is occurring.
Data Sources:
Articles published since 2008.
Study Selections:
Articles on antibiotic allergy and stewardship.
Results:
A number of overlapping factors contribute. The most important factor is antibiotic overuse. Antibiotics are commonly used in situations in which no antibiotics are indicated. Thirty percent to 50% of ambulatory antibiotic use may be inappropriate. The duration of indicated antibiotic use is often excessive, which leads to more side effects. All antibiotic use can result in adverse reactions, and a fraction of these will be dutifully recorded as an allergy in the electronic health record (EHR). Most EHRs are not well structured to accurately convey information on expected side effects that have occurred, metabolic or other contraindications, dose-related or situational toxicities, personal preferences, clinically significant immunologically mediated hypersensitivity, and other reasons a particular patient may not want or should not be given a specific drug or type of drug in the future. As populations age, their accumulated baggage of reported antibiotic allergies increase. Suspected antibiotic allergy is rarely confirmed with appropriate testing or rechallenge. Patients then receive suboptimal antibiotic therapy and experience more side effects, treatment failures, and serious antibiotic-resistant infections. Reporting an antibiotic allergy in the EHR is nominally done to improve patient safety, but unfortunately, this is often not the actual result.
Conclusion:
Audit and feedback, to help ensure adherence to Choosing Wisely recommendations and good antibiotic stewardship practices, can help reduce inappropriate antibiotic use. Restructuring EHRs to facilitate correct drug intolerance reporting, along with active antibiotic allergy delabeling programs, can help stem this epidemic.
Insights
An epidemic of antibiotic allergy is driven by overuse and inaccurate electronic health record (EHR) allergy reporting. Delabeling programs and improved EHRs can help reduce inappropriate antibiotic use and improve patient safety.
Area of Science:
- Medical Science
- Infectious Diseases
- Pharmacology
Background:
- Antibiotic resistance is a growing global health concern.
- Inappropriate antibiotic prescribing contributes significantly to this resistance.
- Electronic health records (EHRs) often inaccurately document antibiotic allergies.
Purpose of the Study:
- To review the contributing factors to the epidemic of antibiotic allergy.
- To highlight the consequences of inaccurate antibiotic allergy documentation.
- To propose solutions for mitigating antibiotic overuse and allergy mislabeling.
Main Methods:
- Literature review of articles published since 2008.
- Analysis of factors contributing to antibiotic overuse.
- Examination of EHR system limitations in reporting drug intolerances.
Main Results:
- Antibiotic overuse is a primary driver, with 30-50% of ambulatory use potentially inappropriate.
- Adverse reactions are frequently misclassified as allergies in EHRs.
- Inaccurate allergy labeling leads to suboptimal treatment, increased side effects, and antibiotic resistance.
Conclusions:
- Audit and feedback mechanisms can reduce inappropriate antibiotic use.
- Restructuring EHRs for accurate intolerance reporting is crucial.
- Active antibiotic allergy delabeling programs are essential to combat this epidemic.

Pharmacovigilance
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
