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.


North America

In modern English, the term ''physician'' is used in two main ways, with relatively broad and narrow meanings respectively. This is the result of history and is often confusing. These meanings and variations are explained below. In the United States and Canada, the term ''physician'' describes all medical practitioners holding a professional medical degree. The

Podiatry residencies and/ or fellowships are not accredited by the ACGME.

Physicians' own health

Some commentators have argued that physicians have duties to serve as role models for the general public in matters of health, for example by not smoking cigarettes. Indeed, in most western nations relatively few physicians smoke, and their professional knowledge does appear to have a beneficial effect on their health and lifestyle.

Hence, gaining a basic medical degree may typically take from five to eight years, depending on jurisdiction and university. Following the completion of entry-level training, newly graduated medical practitioners are often required to undertake a period of supervised practice before full registration is granted, typically one or two years. This may be referred to as an " internship", as the "foundation" years in the UK, or as "conditional registration". Some jurisdictions, including the United States, require residencies for practice. Medical practitioners hold a medical degree specific to the university from which they graduated. This degree qualifies the medical practitioner to become licensed or registered under the laws of that particular country, and sometimes of several countries, subject to requirements for an internship or conditional registration.


Specialists in internal medicine

Specialty training is begun immediately following completion of entry-level training, or even before. In other jurisdictions, junior medical doctors must undertake generalist (un-streamed) training for one or more years before commencing specialization. Hence, depending on the jurisdiction, a specialist physician (internist) often does not achieve recognition as a specialist until twelve or more years after commencing basic medical training—five to eight years at university to obtain a basic medical qualification, and up to another nine years to become a specialist.


Regulation

In most jurisdictions, physicians (in either sense of the word) need government permission to practice. Such permission is intended to promote public safety, and often to protect government spending, as medical care is commonly subsidized by national governments. In some jurisdictions such as in

), the licensing or registration of medical practitioners is done at a state or provincial level, or nationally as in New Zealand. Australian states usually have a "Medical Board", which has now been replaced by the Australian Health Practitioner Regulation Agency (AHPRA) in most states, while Canadian provinces usually have a "College of Physicians and Surgeons". All American states have an agency that is usually called the "Medical Board", although there are alternate names such as "Board of Medicine", "Board of Medical Examiners", "Board of Medical Licensure", "Board of Healing Arts" or some other variation. After graduating from a first-professional school, physicians who wish to practice in the US usually take standardized exams, such as the USMLE for a Doctor in Medicine.


Specialists in internal medicine

Most countries have some method of officially recognizing specialist qualifications in all branches of medicine, including internal medicine. Sometimes, this aims to promote public safety by restricting the use of hazardous treatments. Other reasons for regulating specialists may include standardization of recognition for hospital employment and restriction on which practitioners are entitled to receive higher insurance payments for specialist services.

s, drug abuse, and other issues in physician professional behavior received significant attention across the world, in particular following a critical 2000 report which "arguably launched" the patient-safety movement. In the US, as of 2006 there were few organizations that systematically monitored performance. In the US, only the Department of Veterans Affairs randomly drug tests physicians, in contrast to drug testing practices for other professions that have a major impact on public welfare. Licensing boards at the US state-level depend upon continuing education to maintain competence. Through the utilization of the National Practitioner Data Bank,

In Europe, as of 2009 the health systems are governed according to various national laws, and can also vary according to regional differences similar to the United States.
