Integrated One Health Mixed-Effects Modeling
OH-MEMA leverages a sophisticated mixed-effects modeling approach to integrate diverse data streams—human clinical, environmental, and wastewater—for enhanced syndromic surveillance. This allows for the capture of both population-level trends and group-specific variations, crucial for public health decision-making. The model formulation accounts for non-linear relationships and temporal lag structures, providing a nuanced understanding of disease dynamics. It enhances the interpretability of complex interactions within the One Health paradigm.
Interactive Visual Analytics Framework
The system is designed as an interactive visual analytics framework, enabling domain experts to build, evaluate, and compare models without coding. It features a web-based interface for data upload, predictor selection, and parameter configuration. Key components include STL decomposition for trend and seasonality extraction, anomaly detection with confidence bands, and a provenance tree to track model iterations. This transparent, human-in-the-loop design supports iterative exploration and rapid hypothesis testing in real-time.
Robust Quantitative and Qualitative Validation
OH-MEMA's performance was rigorously assessed through a two-tiered evaluation. Quantitative validation used rolling time-series cross-validation, demonstrating robust predictive accuracy with significantly reduced MAE and RMSE, and improved correlation. Qualitative evaluation, involving epidemiologists and disease surveillance analysts, confirmed high usability, interpretability, and low cognitive workload, reinforcing its suitability for practical public health workflows. This dual validation approach ensures both statistical robustness and user-centered effectiveness.

Case Study: Oklahoma COVID-19 Surveillance
Challenge: Public health officials in Oklahoma needed a unified system to integrate heterogeneous data (human clinical, wastewater, environmental) to predict COVID-19 hospitalizations and cases at the county level, facilitating timely interventions.
OH-MEMA Solution: Implemented a mixed-effects modeling framework with STL decomposition and interactive visual analytics. Users could configure models, select predictors like SARS-CoV-2 wastewater concentrations and Net Effective Temperature (NET), and incorporate random effects for county, month, and age group.
Results: The system demonstrated superior predictive performance. For instance, combining wastewater and NET predictors (M3) with random effects for county, month, and age group yielded a MAE of 0.067, RMSE of 0.093, and correlation of 89.47% for hospitalizations. Month-based random effects often outperformed county-based ones, suggesting effective capture of seasonal patterns. Users praised the system for its interpretability and ease of use.
Impact: Enabled proactive public health surveillance, improved understanding of outbreak dynamics, and supported data-driven decision-making for pandemic preparedness and response in Oklahoma.
