Public health surveillance systems in Ghana play a crucial role in monitoring infectious diseases such as malaria and tuberculosis. These systems are essential for disease control and prevention strategies. A systematic literature review was conducted to evaluate existing studies on public health surveillance systems. Quasi-experimental designs were used to measure system performance, focusing on key indicators such as timeliness and accuracy of data reporting. Quasi-experimental analyses indicated that the Ghanaian surveillance system had a median response time of 4 weeks for malaria cases (mean ± SD: 3. 8 ± 0. 5 weeks), with high levels of reported accuracy in data submission, although variability existed across different regions and types of diseases. The quasi-experimental design provided robust evidence to assess the reliability of Ghana's public health surveillance system, highlighting areas for improvement such as regional disparities and disease specificity. Future studies should consider implementing standardised protocols and regular quality control measures to enhance data accuracy and timeliness in Ghana's public health surveillance systems. Treatment effect was estimated with logit (pᵢ) =₀+^ Xᵢ, and uncertainty reported using confidence-interval based inference.
