Scientific titleThe impact of subsidised artemisinin-based combination therapies distributed through private drug shops on consumer uptake and retail price in rural Tanzania: a non-clinical district-randomised controlled trial
Study objectivesThe introduction of subsidised artemisinin-based combination therapies (ACTs) at the top of the private sector supply chain will lead to a significant increase in consumer purchase and use of these recommended first-line therapies and a corresponding significant decrease in purchase and use of sub-optimal therapies such as amodiaquine and sulphadoxine-pyramethamine.

The lower price for ACTs offered at the top of the supply chain as a result of the subsidy will result in significantly lower retail prices for these drugs, with consumers paying an equivalent amount as for the most commonly purchased suboptimal therapies.
Ethics approval(s)Tanzania Ministry of Health and Social Welfare approved on the 20th July 2007
Health condition(s) or problem(s) studiedMalaria
InterventionA total of four interventions are applied during the project:
1. Provision of ACTs at a price 95% below standard market level to a pharmaceutical wholesaler with agreement to distributed to drug shops
2. Training of drug shop owners and shopkeepers on recognition of malaria symptoms, the importance of use of ACTs as first-line malaria treatment, and proper storage and dispensing practices for ACTs
3. Comprehensive behaviour change communication activities through a variety of media to promote prompt treatment seeking for malaria, demand for and acceptance of ACTs as first-line malaria treatment, and to generate awareness of low-priced ACT in private shops
4. Placement of a suggested retail price on subsidised ACTs distributed through private shops to provide consumers with a clear indication of the appropriate amount to pay for the product
Intervention typeOther
Primary outcome measure(s)

1. Proportion of consumers purchasing anti-malarials at private drug shops that buy ACTs. Measured through exit interviews at all shops in target districts at baseline and four surveys during intervention.
2. Price paid for subsidised ACTs and most common alternative anti-malarials by consumers at private drug shops. Measured through exit interviews and the mystery shopper technique at baseline and four times during intervention.
3. The total volume of ACTs distributed by private drug shops in the previous month. Measured through retail audits conducted twice during each survey period (once to establish baseline stock level and follow-up to measure change due to sales), including baseline.

Key secondary outcome measure(s)

1. Socioeconomic status of consumers purchasing ACT and other anti-malarials at private drug shops as determined through principal component analysis of household assets. Measured through exit interviews of consumers at baseline and four times during intervention.
2. Volume of ACTs dispensed by all public and nongovernmental health facilities in target districts during preceding month. Measured through audits of public facilities and NGO health facilities at baseline and four times during intervention.
3. Proportion of private drug shops stocking ACTs and alternative anti-malarials. Measured through retail audits at baseline and four times during intervention.
4. Geographic location of drug shops and public/NGO health facilities distributing anti-malarials. Measured through recording of GPS coordinates of all drug shops and facilities during each audit using Garmin Etrex hand units.
