Antibiotic prescribing for pediatric respiratory infections varies widely between practices, even after accounting for patient factors. This highlights significant opportunities for improving antimicrobial stewardship in outpatient settings.
Area of Science:
- Pediatric infectious diseases
- Antimicrobial stewardship
- Health services research
Background:
- Outpatient respiratory tract infections are a leading cause of antibiotic prescriptions in children.
- Previous research indicates antibiotic overuse, but lacks detailed data on practice-level variability.
Purpose of the Study:
- To investigate the variability in antibiotic prescribing for pediatric acute respiratory tract infections across different outpatient practices.
- To identify potential determinants of this prescribing variability.
Main Methods:
- Retrospective cohort study of 399,793 acute visits to 25 pediatric practices (222 clinicians) in 2009.
- Data extracted from electronic health records, including diagnoses, medications, and patient demographics.
- Analysis adjusted for patient factors and clinician clustering to compare practice-level prescribing rates.
Main Results:
- 28% of acute visits resulted in antibiotic prescriptions.
- Antibiotic prescribing rates varied from 18% to 36% across practices, with broad-spectrum antibiotic use ranging from 15% to 58%.
- Significant practice-level variation was observed in diagnoses and broad-spectrum antibiotic prescribing for common infections like otitis media, sinusitis, pharyngitis, and pneumonia.
Conclusions:
- Substantial unexplained variability exists in antibiotic prescribing for common pediatric infections among outpatient practices.
- Patient-specific factors do not account for this observed prescribing variation.
- These findings underscore the need for targeted antimicrobial stewardship interventions in pediatric outpatient settings.
