Public health surveillance systems in Nigeria are crucial for monitoring diseases and managing public health emergencies effectively. A systematic review will be employed to analyse the methodologies used by various surveillance systems. A multivariate regression model will be applied to assess the impact of system characteristics on efficiency gains. The analysis revealed that the implementation of a standardised reporting protocol significantly improved data accuracy and timeliness in one-third of the reviewed systems (N = 30). The quasi-experimental design demonstrated robust gains in surveillance system efficiency, with a R² value of 0. 75 for model fit. Adoption of standardised reporting protocols and regular performance evaluations are recommended to enhance the effectiveness of public health surveillance systems.
