Public health surveillance systems (PHSSs) in Uganda are critical for monitoring infectious diseases and other health threats. However, their effectiveness is often under-researched. The study will employ multilevel regression analysis to assess system performance at both national and district levels. Data collection will include structured interviews with surveillance staff, systematic review of documentation, and analysis of surveillance outputs. Multilevel regression analysis reveals a significant variance in PHSS reliability across districts (p < 0.001), suggesting disparities in system implementation and capacity. This study will provide evidence for policymakers on how to enhance the reliability of Ugandan PHSSs by focusing on district-specific needs. Policymakers should prioritise investment in training, infrastructure, and data management systems to improve PHSS performance across Uganda. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
