Oral rehydration program evaluation by quality assurance sampling in rural Haiti

An oral rehydration program in rural Haiti was evaluated by quality assurance sampling. The quality assurance sampling method and its application are described. The indicators measured were knowledge of the oral rehydration salts packet, knowledge of preparation of the solution from the packet, oral rehydration therapy use, and knowledge of preparation of the solution from salt and sugar. Coverages of the first two indicators were adequate, coverages of the latter two were inadequate. The method is a useful low-cost approach to evaluation of program coverage.
