Health care provider


Health care provider


A health care provider is an individual or an institution that provides preventive, curative, promotional or rehabilitative health care services in a systematic way to individuals, families or communities.
An individual health care provider (also known as a health worker) may be a health care professional within medicine, nursing, or a field of allied health. Health care providers may also be a public/community health professional. Institutions (also known as health facilities) include hospitals, clinics, primary care centres, and other service delivery points. The practice of health professionals and operation of health care institutions is typically regulated by national or state/provincial authorities through appropriate regulatory bodies for purposes of quality assurance.[1] Together, they form part of an overall health care system.

Health system


Health system


A health system, also sometimes referred to as health care system or healthcare system is the organization of people, institutions, and resources to deliver 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. In some countries, health system planning is distributed among market participants. In others, there is a concerted effort among governments, trade unions, charities, religious, or other co-ordinated bodies to deliver planned health care services targeted to the populations they serve. However, health care planning has been described as often evolutionary rather than revolutionary.[1][2]

Health human resources


Health human resources


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 health”, according to the World Health Organization's World Health Report 2006.[1] Human resources for health are identified as one of the core building blocks of a health system.[2] They include physicians, nurses, midwives, dentists, allied health professions, community health workers, social health workers and other health care providers, as well as health management and support personnel – those who may not deliver services directly but are essential to effective health system functioning, including health services managers, medical records and health information technicians, health economists, health supply chain managers, medical secretaries, and others.
The field of HRH deals with issues such as planning, development, performance, management, retention, information, and research on human resources for the health care sector. In recent years, raising awareness of the critical role of HRH in strengthening health system performance and improving population health outcomes has placed the health workforce high on the global health agenda.[3]

Health education


Health education


Health education is the profession of educating people about health.[1] Areas within this profession encompass environmental health, physical health, social health, emotional health, intellectual health, and spiritual health.[2] It can be defined as the principle by which individuals and groups of people learn to behave in a manner conducive to the promotion, maintenance, or restoration of health. However, as there are multiple definitions of health, there are also multiple definitions of health education. The Joint Committee on Health Education and Promotion Terminology of 2001 defined Health Education as "any combination of planned learning experiences based on sound theories that provide individuals, groups, and communities the opportunity to acquire information and the skills needed to make quality health decisions." [3] The World Health Organization defined Health Education as "compris[ing] [of] consciously constructed opportunities for learning involving some form of communication designed to improve health literacy, including improving knowledge, and developing life skills which are conducive to individual and community health." [4]

Health policy



Health policy



This article is about policies, plans and strategies across the health care sector. For specific information on health insurance policies, see health insurance.
Health policy can be defined as the "decisions, plans, and actions that are undertaken to achieve specific health care goals within a society."[1] According to the World Health Organization, an explicit health policy can achieve several things: it defines a vision for the future; it outlines priorities and the expected roles of different groups; and it builds consensus and informs people.[1]
There are many categories of health policies, including personal health care policy, pharmaceutical policy, and policies related to public health such as vaccination policy, tobacco control policy or breastfeeding promotion policy. They may cover topics of financing and delivery of health care, access to care, quality of care, and health equity.[2]
There are also many topics in the politics and evidence that can influence the decision of a government, private sector business or other group to adopt a specific policy. Evidence-based policy relies on the use of science and rigorous studies such as randomized controlled trials to identify programs and practices capable of improving policy relevant outcomes. Most political debates surround personal health care policies, especially those that seek to reform health care delivery, and can typically be categorized as either philosophical or economic. Philosophical debates center around questions about individual rights, ethics and government authority, while economic topics include how to maximize the efficiency of health care delivery and minimize costs.
The modern concept of health care involves access to medical professionals from various fields as well as medical technology, such as medications and surgical equipments. It also involves access to the latest information and evidence from research, including medical research and health services research.
In many countries it is left to the individual to gain access to health care goods and services by paying for them directly as out-of-pocket expenses, and to private sector players in the medical and pharmaceutical industries to develop research. Planning and production of health human resources is distributed among labour market participants.
Other countries have an explicit policy to ensure and support access for all of its citizens, to fund health research, and to plan for adequate numbers, distribution and quality of health workers to meet health care goals. Many governments around the world have established universal health care, which takes the burden of health care expenses off of private businesses or individuals through pooling of financial risk. There are a variety of arguments for and against universal health care and related health policies. Health care is an important part of health systems and therefore it often accounts for one of the largest areas of spending for both governments and individuals all over the world. For example, medical debt is now a leading cause of personal bankruptcy in the United States.[3][4]



Health insurance


Health insurance


Health insurance is insurance against the risk of incurring medical expenses among individuals. By estimating the overall risk of health care expenses among a targeted group, an insurer can develop a routine finance structure, such as a monthly premium or payroll tax, to ensure that money is available 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.[1]


Environmental protection


Environmental protection


Environmental protection is a practice of protecting the environment, on individual, organizational or governmental levels, for the benefit of the natural environment and (or) humans. Due to the pressures of population and technology, the biophysical environment is being degraded, sometimes permanently. This has been recognized, and governments have begun placing restraints on activities that caused environmental degradation. Since the 1960s, activism by the environmental movement has created awareness of the various environmental issues. There is not a full agreement on the extent of the environmental impact of human activity, and protection measures are occasionally criticized.
Academic institutions now offer courses, such as environmental studies, environmental management and environmental engineering, that study the history and methods of environmental protection. Protection of the environment is needed from various human activities. Waste, pollution, loss of biodiversity and the introduction of invasive species are some of the issues relating to environmental
