Primary health care, as outlined in the 1978 Declaration of Alma-Ata and again 40 years later in the 2018 WHO/UNICEF document A vision for primary health care in the 21st century: towards universal health coverage and the Sustainable Development Goals, is a whole-of-government and whole-of-society approach to health that combines the following three components: multisectoral policy and action; empowered people and communities; and primary care and essential public health functions as the core of integrated health services.(1) Primary health care-oriented health systems are health systems organized and operated so as to make the right to the highest attainable level of health the main goal, while maximizing equity and solidarity. They are composed of a core set of structural and functional elements that support achieving universal coverage and access to services that are acceptable to the population and that are equity enhancing. The term “primary care” refers to a key process in the health system that supports first-contact, accessible, continued, comprehensive and coordinated patient-focused care.
