A Practical Guide for Managing Antibiotic Allergies in the Emergency Department

Area of Science:

• Clinical Medicine
• Pharmacology
• Infectious Diseases

Background:

• Up to 30% of patients report antibiotic allergies, but misdiagnosis is common, particularly for penicillin allergies (90%-98% are not truly allergic).
• Increasing antibiotic resistance and a scarcity of new antibiotics necessitate accurate allergy assessment for optimal patient care.
• Distinguishing adverse drug reactions from true allergies is challenging, especially in fast-paced emergency settings.

Purpose of the Study:

• To review antibiotic selection strategies for patients reporting antibiotic allergies in the emergency department.
• To highlight the critical need for accurate antibiotic allergy evaluation in the context of rising antibiotic resistance.

Main Methods:

• Systematic review of medical records.
• Patient and/or family interviews.
• Analysis of antibiotic selection in emergency department settings.

Main Results:

• Misdiagnosed antibiotic allergies lead to the selection of inappropriate alternative antibiotics.
• Inaccurate allergy reporting is associated with increased use of broad-spectrum antibiotics.
• Suboptimal antibiotic choices contribute to higher rates of antibiotic resistance and poorer patient outcomes.

Conclusions:

• Accurate antibiotic allergy evaluation is vital for appropriate antibiotic selection.
• A systematic approach combining medical record review and patient interviews is essential.
• Improved allergy assessment can mitigate the overuse of broad-spectrum agents and combat antibiotic resistance.
