Public health's core functions—assessment, policy development, and assurance—form the backbone of population health management. These interconnected activities guide efforts to identify health issues, create effective strategies, and ensure quality health services for communities.
Assessment gathers crucial data on health needs, while policy development crafts targeted solutions. Assurance then implements these policies, enforces regulations, and evaluates outcomes. Together, these functions create a comprehensive approach to protecting and promoting public health.
