s. Because their patients are often seriously ill or require complex investigations, internists do much of their work in hospitals. Formerly, many internists were not subspecialized and would see any complex nonsurgical problem; this style of practice has become much less common.

In modern urban practice, most internists are subspecialists: that is, they generally limit their medical practice to problems of one organ system or to one particular area of medical knowledge. For example, gastroenterologist

Education and training of internists

The training and career pathways for internists vary considerably across the world.

First, they must receive the "entry-level" education required of any medical practitioner in the relevant jurisdiction. The entry-level for medical education programs are tertiary

.

Programs that require previous undergraduate education are usually four or five years in length. Hence, gaining a basic medical education may typically take eight years, depending on jurisdiction and university. Following completion of entry-level training, newly graduated medical practitioners are often required to undertake a period of supervised practice before the licensure

 countries, such trainees are often called registrars.

Training in medical specialties typically takes from three- to 10 years, and sometimes more, depending on specialty and jurisdiction. A medical practitioner who completes specialist training in internal medicine (or in one of its subspecialties) is an internist, or a medical specialist in the older, narrower sense. In some jurisdictions, training in internal medicine is begun immediately following completion of entry-level training, or even before. In other jurisdictions, a medical specialist must undertake generalist (un-streamed) training for one or more years before commencing specialization. Hence, depending on jurisdiction, an internist typically takes 12 or more years after commencing basic medical training — five to eight years at university to obtain a basic medical qualification and up to another six years to become a medical specialist. Internal Medicine subspecialists may also practice general internal medicine, but a particular subspecialty, i.e., cardiology or pulmonology licensure is granted after completing a fellowship
