Bayesian Hierarchical Model Evaluation of Clinical Outcomes in Public Health Surveillance Systems in Kenya,

Key Points

This research aims to evaluate clinical outcomes using a Bayesian hierarchical model within public health surveillance in Kenya.
Utilized a Bayesian hierarchical model for data analysis from multiple public health sources.
Incorporated robust standard errors to account for uncertainty in the data.
Estimated treatment effects using a logit model framework.
Identified a significantly higher proportion of positive cases in respiratory diseases (p < 0.05).
Enhanced accuracy and reliability of public health surveillance data was achieved through Bayesian methods.
Recommended regular calibration of surveillance systems by public health authorities.

Abstract

Public health surveillance systems in Kenya have been established to monitor clinical outcomes across various diseases. A Bayesian hierarchical model was employed to analyse data from multiple sources, incorporating uncertainty through robust standard errors. The model revealed that the proportion of positive cases in respiratory diseases was significantly higher than expected (p < 0. 05). The application of a Bayesian hierarchical model enhanced the accuracy and reliability of surveillance data. Public health authorities should prioritise regular calibration of surveillance systems to ensure consistent performance. Treatment effect was estimated with logit (pᵢ) =₀+^ Xᵢ, and uncertainty reported using confidence-interval based inference.
