Healthcare Delivery Systems

• Definition of Health System (WHO 2007):

1. A health system consists of all organizations, people, and actions whose primary intent is to promote, restore, or maintain health.

2. Includes efforts to influence determinants of health as well as direct health-improving activities.

3. Extends beyond publicly owned facilities delivering personal health services; includes home care (e.g., a mother caring for a sick child), private providers, behavior change programs, vector-control campaigns, health insurance organizations, occupational health and safety legislation, and inter-sectoral actions (e.g., encouraging ministries of education to promote female education).
