[Can use of antibiotics in acute bronchitis be reduced?]
1marfaga@online.no
Background:
Acute bronchitis is one of the most common illnesses treated in the primary care setting. Most patients are treated with antibiotics, despite the fact that acute bronchitis is often a viral infection. There is little evidence that antibiotics are of any value in the treatment of this illness. Inappropriate use of antibiotics in the treatment of this and other infectious diseases contributes to the development of resistant bacteria. The purpose of this study was to reduce the prescribing of antibiotics for acute bronchitis in patients without underlying lung disease in the acute care clinic in Arendal, Norway.
Material And Methods:
The study had three phases, the first of which was a pilot study showing that 87% of patients with acute bronchitis received a prescription for antibiotics. The next phase was an educational intervention in which the physicians were informed of the inappropriately high prescribing rate, the lack of evidence that antibiotics are useful in the treatment of acute bronchitis, and the potential of C reactive protein (CRP) in the diagnose of this illness. The third phase of the study examined the treatment given to patients after the intervention.
Results:
The antibiotic prescribing rate was reduced from 87% to 71% after the intervention. Doxycycline was prescribed most often, followed by penicillin and erythromycin. The use of CRP increased, and the rate of antibiotic prescriptions for patients with CRP < or = 20 was reduced after the intervention. There were fewer bronchitis diagnoses and more pneumonia diagnoses made after the intervention.
Interpretation:
An educational intervention designed for prescribing doctors may reduce the use of antibiotics in the treatment of acute bronchitis.
Insights
An educational intervention for doctors reduced antibiotic prescriptions for acute bronchitis. This initiative aimed to curb antibiotic overuse and combat resistant bacteria, showing a decrease in prescribing rates.
Area of Science:
- Primary care medicine
- Infectious disease management
- Antimicrobial stewardship
Context:
- Acute bronchitis is frequently overtreated with antibiotics despite often being viral.
- Inappropriate antibiotic use fuels the development of antibiotic-resistant bacteria.
- Current primary care practices show high antibiotic prescribing rates for acute bronchitis.
Purpose:
- To decrease antibiotic prescribing for acute bronchitis in primary care.
- To educate physicians on the limited efficacy of antibiotics for acute bronchitis.
- To explore the utility of C-reactive protein (CRP) testing in diagnosis.
Summary:
- A pilot study revealed 87% of acute bronchitis patients received antibiotics.
- An educational intervention informed physicians about high prescribing rates and CRP's diagnostic potential.
- Post-intervention, antibiotic prescribing for acute bronchitis decreased from 87% to 71%.
Impact:
- Reduced antibiotic prescriptions for acute bronchitis by 16% post-intervention.
- Increased utilization of C-reactive protein (CRP) testing in diagnosis.
- Shift in diagnoses, with fewer bronchitis and more pneumonia cases identified.
