Feasibility of a community health worker strategy for providing near and appropriate treatment of malaria in southeast Nigeria: an analysis of activities, costs and outcomes.

摘要

RATIONALE: Community health workers (CHWs) could be used to bring appropriate and timely treatment of malaria closer to home and there is the need to increase the body of knowledge about the feasibility of implementing the strategy. OBJECTIVE: To determine the processes, costs and outcomes of design and implementation of a strategy based on use of CHWs for near and appropriate treatment of malaria. METHODS: The CHW strategy was implemented in two villages (Adu and Ahani) in Enugu state, southeast Nigeria. Adu and Ahani have a population of approximately 3500 and 5000 residents, respectively. The study was conducted in four phases: (1) baseline survey; (2) design; (3) implementation, supervision and monitoring; and (4) evaluation. Interactive meeting with all the stakeholders were used to fine-tune the design of the CHW strategy. Community members that were selected by the project team with the help of community leaders were trained to become CHWs and their remuneration was through commissions on their drug sales. Community and provider's financial and non-financial costs of the startegy were computed. RESULTS: Non-financial costs were the highest contributor to consumer costs, while financial costs constituted more than 90% of provider costs. The total consumer cost in Ahani was USDollars 2548, while the consumer cost in Adu was USDollars 1585. The total provider cost in Ahani was USDollars 4515, while in Adu it was USDollars 4302. The unit cost cost per villager was USDollars 1.40 in Ahani and USDollars 1.70 in Adu, while the unit financial consumer cost per treated patient was Dollars 0.05 in both villages, respectively. The CHWs were acceptable to the people and had an increased market share out of existing malaria treatment provision strategies. CONCLUSION: The cost of starting up the CHW strategy is low and should be affordable to malaria control programs and communities. The CHW strategy is also economically viable and a potential cost-effective source for providing timely, and appropriate treatment of malaria in rural areas. It should be fine-tuned and added to malaria control armamenterium in Nigeria and other parts of sub-Saharan Africa.
