Public health surveillance systems are essential for monitoring infectious diseases in Ethiopia, where they play a critical role in disease detection and control. We employed a fixed effects model (FE) for estimating the impact of various variables on the adoption rate of surveillance systems, accounting for potential heterogeneity across regions. The panel data analysis revealed that facility investment in IT infrastructure significantly increased the adoption rates of public health surveillance systems by 25% compared to those without such investments. Furthermore, a higher proportion (30%) of facilities reported improved disease detection and response times as a result of adopting these systems. Our findings suggest that targeted interventions aimed at enhancing IT capabilities can substantially boost the adoption rates of public health surveillance systems in Ethiopia. To further improve the effectiveness of surveillance systems, it is recommended to provide additional training for healthcare workers and allocate sufficient funding for upgrades to existing infrastructure. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
