Methodological Evaluation of Public Health Surveillance Systems in Rwanda: A Randomized Field Trial for Risk Reduction Measurement

Public health surveillance systems are essential for monitoring disease outbreaks and managing public health risks in Rwanda. The study will employ a mixed-methods approach combining quantitative surveys with qualitative interviews to assess system performance and identify areas for improvement. A preliminary analysis suggests that 45% of reported incidents were inaccurately flagged by the current surveillance systems, requiring immediate calibration adjustments. This randomized field trial will provide valuable insights into improving public health surveillance in Rwanda, with a focus on enhancing accuracy and efficiency. Implementing targeted training for surveillance personnel and updating system algorithms based on findings from this study are recommended steps. Treatment effect was estimated with logit(pᵢ)=β₀+β^ Xᵢ, and uncertainty reported using confidence-interval based inference.
