[Duration of antibiotic therapy for common respiratory infections in adults]

Area of Science:

• Infectious Diseases
• Pharmacology
• Public Health

Background:

• Respiratory tract infections (RTIs) are common in adult outpatients.
• Antibiotic overuse contributes to resistance and side effects.
• Optimizing antibiotic duration is crucial for patient outcomes and healthcare costs.

Approach:

• Literature review of current evidence and guidelines.
• Synthesis of recommendations for antibiotic treatment durations.
• Focus on common outpatient RTIs including pneumonia, COPD exacerbation, otitis media, pharyngitis, and sinusitis.

Key Points:

• Antibiotic therapy is generally not indicated for most adult outpatient RTIs.
• Shorter antibiotic courses are recommended when treatment is mandatory.
• Specific recommended durations: 5 days for community-acquired pneumonia, COPD exacerbation, and acute otitis media; 6 days for pharyngitis; 5-7 days for sinusitis.

Conclusions:

• Shorter antibiotic durations are evidence-based for common RTIs in adults.
• These shorter regimens help mitigate antibiotic resistance, side effects, and healthcare expenses.
• Exclusions apply to severe/complicated infections, resistant organisms, and immunocompromised patients.
