- Design
- Cluster-randomised controlled trial
- Population
- 44 villages or neighbourhoods in Burkina Faso and DR Congo; about 10,400 patient surveys
- Primary outcome
- Change in Watch-group antibiotic use
- Effect
- 26.8%→17.1% vs 13.4%→21.2%; adjusted prevalence ratio 0.33 (0.14–0.78)
CABU-EICO, published in June, was a cluster-randomised trial in 44 villages and neighbourhoods in Burkina Faso and DR Congo. Over nine months, intervention areas received community health education and provider training and feedback based on the WHO AWaRe Antibiotic Book, covering health centres, private clinics, pharmacies and informal vendors.
Watch-group antibiotic use fell from 26.8% to 17.1% of patient encounters in intervention areas and rose from 13.4% to 21.2% in control areas, an adjusted prevalence ratio of 0.33. Patient management, measured by simulated patient visits, did not worsen.
The setting resembles much of Indian primary care, where pharmacies and informal providers dispense a large share of antibiotics. Reaching all of them, not just doctors, is what distinguished this bundle.
- Use the WHO AWaRe framework to choose Access antibiotics first for common infections.
- Include pharmacists and informal providers in stewardship work, not just prescribers.
- Give prescribers feedback on their own Watch-group prescribing rates.
- Expect patient management to hold up when broad-spectrum use falls.
Why it matters
Community dispensers outside hospitals drive much Watch-group use, and they can be reached.
Don't overread it
Baseline use differed between arms and intervals were wide; the effect size is uncertain even if the direction is clear.
The statistics, in plain English
A prevalence ratio of 0.33 means Watch-group use was about a third of the level expected without the intervention. The interval from 0.14 to 0.78 is wide, reflecting only 44 clusters.
