Summary
For acute bronchitis, withholding antibiotics and treating only patients with persistent cough is the most cost-effective approach. This strategy minimizes healthcare costs while ensuring bacterial infections are addressed when necessary.
Area of Science:
- Infectious Diseases
- Health Economics
- Primary Care Medicine
Background:
- Antibiotic prescription for acute bronchitis lacks strong evidence for symptom improvement.
- Current practices may lead to unnecessary antibiotic use and potential future healthcare visits for untreated bacterial infections.
Purpose of the Study:
- To evaluate the cost-effectiveness of different treatment strategies for acute bronchitis.
- To identify the optimal approach from a patient's perspective.
Main Methods:
- Three strategies were compared: (1) watchful waiting with treatment for persistent cough, (2) screening for Mycoplasma pneumoniae/Chlamydia pneumoniae and treating positive cases, and (3) universal antibiotic treatment.
- Cost analysis was conducted from the patient's viewpoint, measuring cost per diagnosed case.
Main Results:
- Withholding antibiotics and treating persistent cough was the most cost-effective strategy under baseline assumptions.
- Universal antibiotic treatment became more cost-effective if patient visit costs exceeded $110, antibiotics cost <$2.72, or bacterial prevalence was >25%.
- Screening strategies were only cost-effective with very low screening test costs.
Conclusions:
- Withholding antibiotics and selectively treating patients with unresolved cough is generally the most cost-effective strategy for acute bronchitis.
- This approach balances treatment needs with economic considerations in primary care.
