Key Points

The research aims to analyze the impact of community health workers on tuberculosis case detection in rural South Africa.
Mixed-methods approach combining qualitative interviews and quantitative data collection.
Utilization of a logistic regression model to evaluate the impact of CHWs.
Comparison of TB case detection rates between CHW and non-CHW areas.
CHWs reported a 25% increase in TB case detection rates in their areas.
The confidence interval for this increase was between 18% and 32%.
Significant improvements in TB control linked to the role of CHWs in rural settings.

Abstract

Tuberculosis (TB) remains a significant public health concern in South Africa, particularly in rural areas where access to healthcare services is limited. A mixed-methods approach combining qualitative interviews with quantitative data collection, including a logistic regression model to assess CHW impact on TB case detection rates. Community health workers reported an average of 25% increase in TB case detection rates compared to non-CWH areas (95% CI: 18-32%). CHWs play a crucial role in TB control, with significant improvements noted in rural South African settings. Enhanced CHW training and resource allocation are recommended for sustained effectiveness. Community Health Workers, Tuberculosis Control, Rural Settings, Logistic Regression Treatment effect was estimated with logit (pᵢ) =₀+^ Xᵢ, and uncertainty reported using confidence-interval based inference.
