This term is at least nine hundred years old in English: 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."

Royal College of Physicians in 1518. It was not until 1540 that he granted the

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
American Medical Association, established in 1847, as well as the
American Osteopathic Association, founded in 1897, both currently use the term ''physician'' to describe members. However, the
American College of Physicians, established in 1915, does not: its title uses ''physician'' in its original sense.
American 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
A medical school is a tertiary educational institution, or part of such an institution, that teaches medicine, and awards a professional degree for physicians. Such medical degrees include the Bachelor of Medicine, Bachelor of Surgery (MBBS, M ...
, 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.

Primary care physicians guide patients in preventing disease and detecting health problems early while they are still treatable. They are divided into two types:

doctors and
internal medicine doctors. Family doctors, or family physicians, are trained to care for patients of any age, while internists are trained to care for adults. Family doctors receive training in a variety of care and are therefore also referred to as
general practitioners. Family medicine grew out of the general practitioner movement of the 1960s in response to the growing specialization in medicine that was seen as threatening to the doctor-patient relationship and continuity of care.
Podiatrists
In the United States, the
American Podiatric Medical Association (APMA) defines
podiatrists as physicians and surgeons who treat the foot, ankle, and associated structures of the leg. Podiatrists undergo training with the
Doctor of Podiatric Medicine (DPM) degree. The
American Medical Association (AMA), however, advocates for the definition of a ''physician'' as "an individual possessing degree of either a
Doctor of Medicine or
Doctor of Osteopathic Medicine." In the US, podiatrists are required to complete three to four years of podiatry residency upon graduating with a DPM degree. After residency, one to two years of fellowship programs are available in plastic surgery, foot and ankle reconstructive surgery, sports medicine, and wound care.
Podiatry residencies and/ or fellowships are not accredited by the
ACGME. The overall scope of podiatric practice varies from state to state and is not similar to that of physicians holding an MD or DO degree. DPM is also available at one Canadian university, namely the
Université du Québec à Trois-Rivières; students are typically required to complete an internship in New York prior to the obtention of their professional degree. The
World Directory of Medical Schools does not list US or Canadian schools of podiatric medicine as ''medical schools'' and only lists US-granted MD, DO, and Canadian MD programs as medical schools for the respective regions.
Shortage
Many countries in the developing world have the problem of too few physicians. In 2015, the
Association of American Medical Colleges warned that the US will face a doctor shortage of as many as 90,000 by 2025.

. This style of medicine is now dominant throughout the industrialized world, and is often termed ''
biomedicine'' by
medical anthropologists.
Biomedicine "formulates the human body and disease in a culturally distinctive pattern",
and is a
world view learnt by medical students. Within this tradition, the
medical model is a term for the complete "set of procedures in which all doctors are trained",
including mental attitudes. A particularly clear expression of this world view, currently dominant among conventional physicians, is
evidence-based medicine
Evidence-based medicine (EBM) is "the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients". The aim of EBM is to integrate the experience of the clinician, the values of t ...

, often combined with expectations of a high and stable income and
job security. However, medical practitioners often work long and inflexible hours, with shifts at unsociable times. Their high status is partly from their extensive training requirements, and also because of their occupation's special
ethical and
legal duties. The term traditionally used by physicians to describe a person seeking their help is the word ''patient'' (although one who
visits a physician for a routine
check-up may also be so described). This word
patient is an ancient reminder of medical duty, as it originally meant 'one who suffers'. The English noun comes from the
Latin word ''patiens'', the
present participle of the
deponent verb,
patior, meaning 'I am suffering', and akin to the
Greek verb (

πάθος (

Physicians in the original, narrow sense (specialist physicians or internists, see above) are commonly members or fellows of professional organizations, such as the
American College of Physicians or the
Royal College of Physicians in the United Kingdom, and such hard-won membership is itself a mark of status.

in various guises: "As long as life had its own secret properties, it was possible to have sciences and medicines based on those properties". The US
National Center for Complementary and Alternative Medicine (NCCAM) classifies
complementary and alternative medicine therapies into five categories or domains, including:
alternative medical systems, or complete systems of therapy and practice;
mind-body interventions, or techniques designed to facilitate the mind's effect on bodily functions and symptoms; biologically based systems including
herbalism; and manipulative and body-based methods such as
chiropractic and massage therapy.
In considering these alternate traditions that differ from biomedicine (see above),
medical anthropologists emphasize that all ways of thinking about health and disease have a significant cultural content, including conventional western medicine.

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. According to a study of male physicians,
life expectancy is slightly higher for physicians (73 years for white and 69 years for black) than lawyers or many other highly educated professionals. Causes of death which are less likely to occur in physicians than the general population include respiratory disease (including

and self-inflicted injury, drug-related causes, traffic accidents, and cerebrovascular and ischaemic heart disease.[ Physicians are also prone to occupational burnout. This manifests as a long-term stress reaction characterized by poorer quality of care towards patients, emotional exhaustion, a feeling of decreased personal achievement, and others. A study by the Agency for Healthcare Research and Quality reported that time pressure was the greatest cause of burnout; a survey from the American Medical Association reported that more than half of all respondents chose "too many bureaucratic tasks" as the leading cause of burnout.

Education and training
Medical education and career pathways for doctors vary considerably across the world.

or require pre-requisite undergraduate education. The former commonly takes five or six years to complete. Programs that require previous undergraduate education (typically a three- or four-year degree, often in science) are usually four or five years in length. 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 Singapore, it is common for physicians to inflate their qualifications with the title "Dr" in correspondence or namecards, even if their qualifications are limited to a basic (e.g., bachelor level) degree. In other countries such as Germany, only physicians holding an academic doctorate may call themselves doctor – on the other hand, the European Research Council

), 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.
Performance and professionalism supervision
The issue of medical errors, 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, Federation of State Medical Boards' disciplinary report, and American Medical Association Physician Profile Service, the 67 State Medical Boards continually self-report any adverse/disciplinary actions taken against a licensed physician in order that the other Medical Boards in which the physician holds or is applying for a medical license will be properly notified so that corrective, reciprocal action can be taken against the offending physician. 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.
