Primary Health Care (PHC) is essential health care made universally accessible to individuals and acceptable to them, through their full participation and at a cost the community and country can afford. Declared at Alma-Ata in 1978, it remains the foundation of global health systems.

Basic Health Care Services (BHCS) refers to the constitutionally guaranteed, free minimum package of health services provided by the state (often contextualized by national policies, ensuring no one is denied emergency or basic care).

The components of these frameworks dictate specific, actionable areas of health intervention. PHC is traditionally defined by its 8 essential elements. The SDGs expand on this with a massive, holistic framework where Goal 3 focuses directly on health, but relies on all other goals.

The transition from MDGs to SDGs shifted the global focus from vertical disease programs to horizontal health systems strengthening, encapsulated in Universal Health Coverage (UHC). Analyzing the status involves understanding coverage gaps, catastrophic health expenditures, and future prospects.
