In Simple Words
A health worker carries a retail basket containing both high-demand commercial goods (like soap and solar lights) and low-margin medical supplies (like zinc and water filters). The steady sales of daily necessity goods fund regular household visits, where the promoter also educates families on preventive healthcare and sells life-saving medical treatments.
Households in Uganda study villages
- No study health promoter
- 37.3% knew untreated water transmits diarrhea
- Study health promoter
- 41.4% knew untreated water transmits diarrhea
Three years after rollout, 41.4% of households in program villages knew untreated water transmits diarrhea, compared with 37.3% in comparison villages. The retail pricing component was not tested separately. Three-year whole-program comparison. Cross-subsidized sales were not tested separately; usual health services available in both groups.
See source →Research question
Essential health-promoting items such as antimalarial bed nets, water purification tablets, and oral rehydration salts are frequently unavailable or underutilized in remote rural households due to distribution gaps and limited health literacy.
Participants
~7,000 households and >11,000 children across 214 rural villages in Uganda.
Study Design
Randomized Controlled Trial (RCT) measuring household knowledge, product adoption, and curative practices across treatment and comparison villages after 3 years.
Results
Water treatment knowledge rose from 37.3% to 41.4% (11% increase), zinc knowledge for diarrhea treatment rose from 22.7% to 26.3% (16% increase), malaria etiology knowledge rose from 7.1% to 9.8% (38% increase), and water treatment behavior reached 81.2% versus 77.4% in comparison villages.
Takeaway
Establish a wholesale retail channel supplying community health promoters with goods at 30% below retail price, enabling them to resell at 10% below market price to maintain consumer affordability while earning a profit margin.
