Dr. Salma Burton's presentation outlines the six key building blocks of an effective health system: 1) service delivery, 2) health workforce, 3) health information systems, 4) medical products/vaccines/technologies, 5) health financing, and 6) governance. Each building block plays an important role in ensuring people have access to safe, effective, and quality health services. Strong leadership and coordination across these areas through a systems thinking approach can help improve overall population health outcomes.
