Clinic
A clinic or outpatient clinic are originally small private or public health facility that provide health care for ambulatory patients or clients in a community, in contrast to inpatients treated in a hospital. Some grow to be institutions as large as major hospitals, whilst retaining the name Clinic. General practice clinics are run by one or more general practitioners or practice managers. Physiotherapy clinics are usually operated by physiotherapists and psychology clinics by clinical psychologists, and so on for each health profession. Some clinics are operated in-house by employers, government organizations or hospitals and some clinical services are outsourced to private corporations, specialising in provision of health services. In China, for example, owners of those clinics do not have formal medical education. Health care in India, China, Russia and Africa is provided to vast rural areas by mobile health clinics or roadside dispensaries, some of which integrate traditional health practices. In India these traditional clinics provide ayurvedic medicine and unani herbal medical practice. In each of these countries traditional medicine tends to be an hereditary practice.
The function of clinics will differ from country to country. For instance, a local general practice run by a single general practitioner will provide primary health care and will usually be run as a for-profit business by the owner whereas a government specialist clinic may provide subsidized specialized health care.
Some clinics function as a place for people with injuries or illnesses to come and be seen by triage nurse or other health worker.  In these clinics, the injury or illness may not be serious enough to warrant a visit to an emergency room, but the person can be moved to one if required.  Treatment at these clinics is often less expensive than it would be at a casualty department.  Also, unlike an ER these clinics are often not open on a 24 x 7 x 365 basis. They sometimes have access to diagnostic equipment such as X-ray machines, especially if the clinic is part of a larger facility.  Doctors at such clinics can often refer patients to specialists if the need arises.
