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 has decided that the German medical doctorate does not meet the international standards of a PhD research degree.dubious – discuss

All medical practitioners

Among the English-speaking countries, this process is known either as licensure as in the United States, or as registration in the United Kingdom, other Commonwealth countries, and Ireland. Synonyms in use elsewhere include colegiación in Spain, ishi menkyo in Japan, autorisasjon in Norway, Approbation in Germany, and άδεια εργασίας in Greece. In France, Italy and Portugal, civilian physicians must be members of the Order of Physicians to practice medicine.

In some countries, including the United Kingdom and Ireland, the profession largely regulates itself, with the government affirming the regulating body's authority. The best-known example of this is probably the General Medical Council of Britain. In all countries, the regulating authorities will revoke permission to practice in cases of malpractice or serious misconduct.

In the large English-speaking federations (United States, Canada, Australia), 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 Australian states usually have a "Medical Board," which has now been replaced by the Australian Health Practitioner Regulatory Authority (AHPRA) in most states, while Canadian provinces usually have a "College of Physicians and Surgeons".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.
