, considered to be the founder of
experimental biology, was the first to recognize and correctly describe details of many important
parasites. The term
doctor commonly refers to medical practitioners across the world, but may also be applied to holders of non-medical
doctoral degrees. While the term
physician is used in North America to refer to medical practitioners in a general sense, in the
United Kingdom and countries influenced by British English this word refers to
specialists in
internal medicine specifically.
British and Commonwealth The British meaning of the term
physician is the original one, and is used in opposition to
surgeon, which refers to a specialist in
surgery. This meaning of physician conveys a sense of expertise in treatment with
drugs, rather than with the manual procedures used by a surgeon. The English word
physician is at least nine hundred years old: physicians and surgeons were once members of separate professions, and traditionally were rivals. The
Shorter Oxford English Dictionary, third edition, gives a
Middle English quotation making this contrast, from as early as 1400: "O Lord, whi is it so greet difference betwixe a cirugian and a physician." Newer universities would probably describe such an academic as a professor of
internal medicine. Hence, in the 16th century,
physic meant roughly what internal medicine does now. This original use is common in much of the world including the United Kingdom and other Commonwealth countries (such as
Australia,
Bangladesh,
India,
New Zealand,
Pakistan,
South Africa,
Sri Lanka, and
Zimbabwe), as well as in places as diverse as
Brazil,
Hong Kong,
Indonesia,
Japan,
Ireland, and
Taiwan. In such places, the more general terms
doctor or
medical practitioner are used to describe any person whose practises medicine. In Britain, the use of the term "doctor" for medical practitioners is a courtesy and does not indicate possession of a doctorate; British doctors must have a
Bachelor of Medicine, Bachelor of Surgery to practise. Community-oriented providers of
primary care are called
general practitioners, commonly abbreviated to GP.
North American , the first female physician in the United States, graduated from
SUNY Upstate. In the United States and Canada, the term
physician describes all medical practitioners holding a professional medical degree. The
American Medical Association (AMA), established in 1847, as well as the
American Osteopathic Association, founded in 1897, both currently use the term
physician to describe members. The AMA advocates for the definition of a
physician as "an individual possessing degree of either a
Doctor of Medicine or
Doctor of Osteopathic Medicine." However, the
American College of Physicians, established in 1915, use the term
physician in its original sense. Specialists in internal medicine may be described as an
internist. Another term,
hospitalist, was introduced in 1996, to describe US specialists in
internal medicine who work largely or exclusively in hospitals. Such "hospitalists" now make up about 19% of all US
general internists, who are often called
general physicians in
Commonwealth countries. In North America, community-oriented providers of
primary care are called
family doctors or
primary care physicians. The vast majority of
physicians trained in the United States have a
Doctor of Medicine degree, and use the initials M.D. A smaller number attend
osteopathic medical schools and have a
Doctor of Osteopathic Medicine degree and use the initials
D.O. The
World Directory of Medical Schools lists both MD and DO granting schools as
medical schools located in the United States. After completion of
medical school, physicians complete a
residency in the specialty in which they will practice. Subspecialties require the completion of a
fellowship after residency. Both MD and DO physicians participate in the
National Resident Matching Program (NRMP) and attend
ACGME-accredited residencies and fellowships across all medical
specialties to obtain licensure. All boards of certification now require that physicians demonstrate, by examination, continuing mastery of the core knowledge and skills for a chosen specialty. Recertification varies by particular specialty between every seven and every ten years.
Physician and surgeon Around the world, the combined term
physician and surgeon is used to describe either a general practitioner or any medical practitioner irrespective of specialty. This usage still shows the original meaning of physician and preserves the old difference between a physician, as a practitioner of
physic, and a surgeon. The term may be used by state medical boards in the United States, and by equivalent bodies in Canadian provinces, to describe any medical practitioner. ==Supply and demand==
