Abstract:
INTRODUCTION : South Africa is an upper middle-income country with wide wealth inequality. It faces a quadruple
burden of disease and poor health outcomes, with access to appropriate and adequate health care a challenge for
millions of South Africans. The introduction of large-scale, comprehensive community health worker (CHW) programs
in the country, within the context of implementing universal health coverage, was anticipated to improve population
health outcomes. However, there is inadequate local (or global) evidence on whether such programs are effective,
especially in urban settings.
METHODS : This study is part of a multi-method, quasi-experimental intervention study measuring effectiveness of a
large-scale CHW program in a health district in an urban province of South Africa, where CHWs now support approximately
one million people in 280,000 households. Using interviewer administered questionnaires, a 2019 cross-sectional
survey of 417 vulnerable households with long-term CHW support (intervention households) are compared to
417 households with no CHW support (control households). Households were selected from similar vulnerable areas
from all sub-levels of the Ekurhuleni health district.
RESULTS : The 417 intervention and control households each had good health knowledge. Compared to controls,
intervention households with long-term comprehensive CHW support were more likely to access early care, get diagnosed
for a chronic condition, be put on treatment and be well controlled on chronic treatment. They were also more
likely to receive a social grant, and have a birth certificate or identity document. The differences were statistically significant
for social support, health seeking behavior, and health outcomes for maternal, child health and chronic care.
CONCLUSION : A large-scale and sustained comprehensive CHW program in an urban setting improved access to social
support, chronic and minor acute health services at household and population level through better health-seeking
behavior and adherence to treatment. Direct evidence from households illustrated that such community health
worker programs are therefore effective and should be part of health systems in low- and middle-income countries.
