A health system, health care system or healthcare system is an organization of people, institutions, and resources that delivers health care services to meet the health needs of target populations.
There is a wide variety of health systems around the world, with as many histories and organizational structures as there are nations. Implicitly, nations must design and develop health systems in accordance with their needs and resources, although common elements in virtually all health systems are primary healthcare and public health measures.[1]
In certain nations, the orchestration of health system planning is decentralized, with various stakeholders in the market assuming responsibilities. In contrast, in other regions, a collaborative endeavor exists among governmental entities, labor unions, philanthropic organizations, religious institutions, or other organized bodies, aimed at the meticulous provision of healthcare services tailored to the specific needs of their respective populations. Nevertheless, it is noteworthy that the process of healthcare planning is frequently characterized as an evolutionary progression rather than a revolutionary transformation.[2][3]
As with other social institutional structures, health systems are likely to reflect the history, culture and economics of the states in which they evolve. These peculiarities bedevil and complicate international comparisons and preclude any universal standard of performance.
