A health system, health care system, or healthcare system, is a set of organizations, institutions and resources whose primary goal is to produce actions for the promotion, restoration or maintenance of health.
There is a wide variety of health systems around the world, with as many histories and organizational structures as there are countries. Implicitly, countries 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.
In certain countries, 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.
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.
How this connects to Community Medicine
Health-system study examines how resources, governance, workforce, information and care pathways affect population outcomes. An intervention should be evaluated for effectiveness, implementation feasibility, equity, cost and unintended consequences in the population actually served.

What the underlying subject studies
Community medicine studies health in populations, including how disease occurs, how it can be prevented and how services reach people. Define the population and time period before interpreting counts, rates, proportions or observed associations.
How mechanisms and evidence connect
Screening, surveillance, vaccination and health-system interventions have benefits, costs and possible harms. Methods must account for selection, confounding, measurement error and inequalities in access.
How to develop a sound explanation
Organize an issue as magnitude, determinants, prevention, implementation and evaluation. Community-level policy or study evidence may not directly apply to an individual patient or a different population.
