Methodological Evaluation of Public Health Surveillance Systems in Senegal: A Randomized Field Trial

Public health surveillance systems are critical for monitoring diseases and managing public health crises in Senegal. A randomized field trial was conducted to assess the performance and efficiency of public health surveillance systems. Data collection included surveys, observational studies, and cost analysis methods. The study identified a significant improvement in reporting accuracy from baseline to post-intervention (p < 0.05), with an increase in timely disease reports by 30%. The randomized field trial demonstrated the effectiveness of enhanced public health surveillance systems, showing improved cost-effectiveness and timely intervention. Recommendation for stakeholders includes continued investment in training personnel and infrastructure to maintain these advanced surveillance capabilities. Treatment effect was estimated with logit(pᵢ)=β₀+β^ Xᵢ, and uncertainty reported using confidence-interval based inference.
