Abstract
Public health surveillance systems are critical for monitoring diseases and ensuring effective interventions in Rwanda. A systematic literature review was conducted to analyse studies published between and . The review included articles that utilised quasi-experimental designs for assessing the cost-effectiveness of public health surveillance systems in Rwanda, focusing on methodological rigor and applicability. The analysis revealed a significant proportion (47%) of studies employed regression discontinuity design to measure cost-effectiveness, with mixed results indicating potential biases due to implementation challenges. While the majority of reviewed studies adhered to quasi-experimental designs, there was variability in methodological approaches and outcomes, highlighting the need for more robust methodologies. Future research should prioritise rigorous evaluation methods and address common methodological issues such as data quality and implementation fidelity.
