General practice is the term used in various nations, such as the United Kingdom, Australia New Zealand and South Africa. Such services are provided by General practitioners. The term Primary Care in the UK may also include services provided by community pharmacy, optometrist, dental surgery and community hearing care providers. The balance of care between primary care and secondary care - which usually refers to hospital based services - varies from place to place, and with time. In many countries there are initiatives to move services out of hospitals into the community, in the expectation that this will save money and be more convenient.
