Community health worker

Community health workers (CHW) are members of a community who are chosen by community members or organizations to provide basic health and medical care to their community. Other names for this type of health care provider include village health worker, community health aide, community health promoter, and lay health advisor.

In many developing countries, especially in Sub-Saharan Africa, there are critical shortages of highly educated health professionals. Current medical and nursing schools cannot train enough workers to keep up with increasing demand for health care services, internal and external emigration of health workers, deaths from AIDS and other diseases, low workforce productivity, and population growth. Community health workers are given a limited amount of training, supplies and support to provide essential primary health care services to the population. Programs involving CHW in China, Brazil, Iran and Bangladesh have demonstrated that utilizing such workers can help improve health outcomes for large populations in under-served regions. "Task shifting" of primary care functions from professional health workers to community health workers is considered to be a means to make more efficient use of the human resources currently available and improving the health of millions at reasonable cost.

Community health

Community health, a field of public health, is a discipline which concerns itself with the study and improvement of the health characteristics of biological communities. While the term community can be broadly defined, community health tends to focus on geographical areas rather than people with shared characteristics. The health characteristics of a community are often examined using geographic information system (GIS) software and public health datasets. Some projects, such as InfoShare or GEOPROJ combine GIS with existing datasets, allowing the general public to examine the characteristics of any given community in participating countries.

Because 'health III' (broadly defined as well-being) is influenced by a wide array of socio-demographic characteristics, relevant variables range from the proportion of residents of a given age group to the overall life expectancy of the neighborhood/community. Medical interventions aimed at improving the health of a community range from improving access to medical care to public health communications campaigns. Recent research efforts have focused on how the built environment and socio-economic status affect health.

Health professional

A health professional or healthcare provider is an individual who provides preventive, curative, promotional or rehabilitative health care services in a systematic way to people, families or communities.

A health professional may operate within all branches of health care, including medicine, surgery, dentistry, midwifery, pharmacy, psychology, nursing or allied health professions. A health professional may also be a public/community health expertee working for the common good of the society.

Practitioners and professionals

Healthcare practitioners include physicians, dentists, pharmacists, physician assistants, nurses, advanced practice registered nurses, surgeons, surgeon's assistant, athletic trainers, surgical technologist, midwives, dietitians, therapists, psychologists, chiropractors, clinical officers, social workers, phlebotomists, occupational therapists, physical therapists, radiographers, respiratory therapists, audiologists, speech pathologists, optometrists, emergency medical technicians, paramedics, medical laboratory scientists, medical prosthetic technicians and a wide variety of other human resources trained to provide some type of health care service. They often work in hospitals, healthcare centres, and other service delivery points, but also in academic training, research, and administration. Some provide care and treatment services for patients in private homes. Many countries have a large number of community health workers who work outside formal healthcare institutions. Managers of healthcare services, health information technicians, and other assistive personnel and support workers are also considered a vital part of health care teams.

Health

Health is the level of functional or metabolic efficiency of a living organism. In humans it is the ability of individuals or communities to adapt and self-manage when facing physical, mental or social challenges. The World Health Organization (WHO) defined health in its broader sense in its 1948 constitution as "a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity." This definition has been subject to controversy, in particular as lacking operational value and because of the problem created by use of the word "complete" Other definitions have been proposed, among which a recent definition that correlates health and personal satisfaction. Classification systems such as the WHO Family of International Classifications, including the International Classification of Functioning, Disability and Health (ICF) and the International Classification of Diseases (ICD), are commonly used to define and measure the components of health. Health is that balanced condition of the living organism in which the integral, harmonious performance of the vital functions tends to the preservation of the organism and the normal development of the individual.

Community

A community is a social unit of any size that shares common values, or that is situated in a given geographical area (e.g. a village or town). It is a group of people who are connected by durable relations that extend beyond immediate genealogical ties, and who mutually define that relationship as important to their social identity and practice. Although communities are usually small, community may also refer to large groups, such as national communities, international communities, and virtual communities.

The word "community" is derived from the Old French comuneté which comes from the Latin communitas (from Latin communis, things held in common).

In human communities, intent, belief, resources, preferences, needs, and risks, may be shared in common, affecting the identity of the participants, and their degree of cohesiveness.

Perspectives from various disciplines

Community studies

Community studies is an academic field drawing on both sociology and anthropology and the social research methods of ethnography and participant observation in the study of community. In academic settings around the world, community studies is variously a sub-discipline of anthropology or sociology, or an independent discipline. It is often interdisciplinary and geared toward practical applications rather than purely theoretical perspectives. Community studies is sometimes combined with other fields, i.e., "Urban and Community Studies," "Health and Community Studies," or "Family and Community studies."
