AI and public health: Charting a path to smarter decision-making

Kapoor, Madhur (2025) AI and public health: Charting a path to smarter decision-making. Global Journal of Engineering and Technology Advances, 23 (1). pp. 445-453. ISSN 2582-5003

Artificial intelligence is fundamentally transforming public health decision-making through sophisticated computational techniques that analyze complex health data at unprecedented scale and speed. This technical article examines how AI technologies are being integrated into public health systems to enhance disease surveillance, optimize resource allocation, and address health inequities. The paper explores multimodal data integration for outbreak detection, census-level analytics for chronic disease risk assessment, and applications in health system planning including social determinants analysis and emergency resource optimization. Methodological considerations regarding model architecture selection and validation frameworks are discussed, highlighting the balance between complex deep learning approaches and more interpretable models. The article addresses critical ethical challenges including data privacy architectures and bias mitigation strategies necessary for responsible implementation. Future research directions are identified, including causal AI methodologies, multimodal learning systems, adaptive models that update with evolving health patterns, and explainable AI techniques. Throughout, the article emphasizes that successful AI integration depends not only on technical sophistication but also on thoughtful implementation that balances computational capabilities with human expertise and judgment within appropriate governance frameworks.
