Evaluation of a peri-urban community health worker project in the western Cape.

The South African Christian Leadership Assembly (SACLA) Health Project is a non-governmental organisation that runs a community health worker (CHW) programme in 4 peri-urban townships of Cape Town. A cross-sectional descriptive community survey was conducted in April 1990 to evaluate coverage and health education on oral rehydration solution (ORS) and to plan future preventive, promotive and development programmes. Research concepts and methods were made accessible to the CHWs through a training process designed to facilitate participation in every stage of the research. A multi-stage cluster sampling scheme was used, and the CHWs interviewed 822 residents. Coverage indicators showed that over 80% of all respondents had previously known about or consulted the CHW. The most common community problems related to water, filth and refuse, toilets, housing, unemployment and lack of community facilities. The most common health problems were generalised aches and pains, chest problems, skin problems, worms, and diarrhoea. An index developed to measure knowledge of ORS showed very few respondents had 'complete knowledge'. The community's expectations of the CHW included health education, attending to sanitation problems, providing a clean environment, organising community facilities, and helping with employment.
