Global North and Global South are terms that denote a method of grouping countries based on their defining characteristics with regard to socioeconomics and politics. According to UN Trade and Development (UNCTAD), the Global South broadly comprises Africa, Latin America and the Caribbean, Asia (excluding Israel, Japan, and South Korea), and Oceania (excluding Australia and New Zealand). Most of the Global South's countries are commonly identified as lacking in their standard of living, which includes having lower incomes, high levels of poverty, high population growth rates, inadequate housing, limited educational opportunities, and deficient health systems, among other issues. Additionally, these countries' cities are characterized by their poor infrastructure. Opposite to the Global South is the Global North, which the UNCTAD describes as broadly comprising Northern America and Europe, Israel, Japan, South Korea, Australia, and New Zealand. Consequently the two groups do not correspond to the Northern Hemisphere or the Southern Hemisphere, as many of the Global South's countries are geographically located in the north and vice-versa.

More specifically, the Global North consists of the world's developed countries, whereas the Global South consists of the world's developing countries and least developed countries. The Global South classification, as used by governmental and developmental organizations, was first introduced as a more open and value-free alternative to Third World, and likewise potentially "valuing" terms such as developed and developing. Countries of the Global South have also been described as being newly industrialized or in the process of industrializing. Many of them are current or former subjects of colonialism.

Health human resources (HHR) – also known as human resources for health (HRH) or health workforce – is defined as "all people engaged in actions whose primary intent is to enhance positive health outcomes", according to World Health Organization's World Health Report 2006. Human resources for health are identified as one of the six core building blocks of a health system. They include physicians, nursing professionals, pharmacists, midwives, dentists, allied health professions, community health workers, and other social service and health care providers.

Health human resources are further composed of health management and support personnel: those who do not provide direct patient care but add important value to enhance health system efficiency, effectiveness and equity. They include health services managers, medical records and health information technicians, health economists, health supply chain managers, medical secretaries, facility maintenance workers, and others.

In world-systems theory, periphery countries are those that are less developed than the semi-periphery and core countries. These countries usually receive a disproportionately small share of global wealth. They have weak state institutions and are dependent on—and, according to some, exploited by—more developed countries. These countries are usually behind because of obstacles such as lack of technology, unstable government, and poor education and health systems. In some instances, the exploitation of periphery countries' agriculture, cheap labor, and natural resources aid core countries in remaining dominant. This is best described by dependency theory, which is one theory on how globalization can affect the world and the countries in it. It is, however, possible for periphery countries to rise out of their status and move into semi-periphery or core status. This can be done by doing things such as industrializing, stabilizing the government and political climate, etc.

Health insurance or medical insurance (also known as medical aid in South Africa) is a type of insurance that covers the whole or a part of the risk of a person incurring medical expenses. As with other types of insurance, risk is shared among many individuals. By estimating the overall risk of health risk and health system expenses over the risk pool, an insurer can develop a routine finance structure, such as a monthly premium or payroll tax, to provide the money to pay for the health care benefits specified in the insurance agreement. The benefit is administered by a central organization, such as a government agency, private business, or not-for-profit entity.

According to the Health Insurance Association of America, health insurance is defined as "coverage that provides for the payments of benefits as a result of sickness or injury. It includes insurance for losses from accident, medical expense, disability, or accidental death and dismemberment".

A pragmatic clinical trial (PCT), sometimes called a practical clinical trial (PCT), is a clinical trial that focuses on correlation between treatments and outcomes in real-world health system practice rather than focusing on proving causative explanations for outcomes, which requires extensive deconfounding with inclusion and exclusion criteria so strict that they risk rendering the trial results irrelevant to much of real-world practice.

The wellbeing services counties (Finnish: hyvinvointialue, Swedish: välfärdsområde, Northern Sami: buresveadjinguovlu, Inari Sami: pyereestvaijeemkuávlu, Skolt Sami: pueʹrrvââjjamvuʹvdd) are responsible for organising health, social and emergency services in Finland. There are 21 wellbeing services counties and the county division is mainly based on the region division. The public authorities are separate from the municipalities and from the central government.

The wellbeing services counties are self-governing. They do not have the right to levy taxes and their funding is based on central government funding. The central government allocates different amounts of funding to the different wellbeing services counties, depending on the structure of their population.
