Health Information Systems for Public Health Surveillance and Decision-Making

Abstract

Health Information Systems (HIS) are central to effective public health surveillance and evidence-based decision making, enabling the systematic collection, integration, analysis, and dissemination of population-level health data. Rapid digitalization of healthcare, alongside the widespread adoption of electronic health records, disease registries, laboratory information systems, and surveillance platforms, has significantly enhanced the capacity of public health systems to monitor health trends, detect outbreaks, and support policy and programmatic interventions (World Health Organization [WHO], 2018; Centers for Disease Control and Prevention [CDC], 2022).
