Public health surveillance systems are essential for monitoring disease outbreaks and managing public health crises efficiently. A systematic review will be conducted to identify, assess, and synthesize studies related to public health surveillance in Rwanda. Studies will be screened using predefined inclusion criteria, and a narrative synthesis approach will be employed for data aggregation. The analysis indicates that the majority of reviewed studies focus on disease-specific monitoring with limited comparative analyses across different systems. While current methods provide valuable insights, there is room for improvement in comparing cost-effectiveness among surveillance systems. Further research should explore comprehensive comparisons and incorporate additional metrics to enhance the evaluation process. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
