National Internal Medicine Day


National Internal Medicine Day recognizes the contributions of more than 300,000 internal medicine physicians on October 28th annually. Internal medicine physicians (internists) are specialists. They apply scientific knowledge and clinical expertise to the diagnosis and treatment. Additionally, they provide compassionate care to adults across the spectrum from health to complex illness. Some internists take additional training to subspecialize in a more focused area of internal medicine. Their subspecialties may include cardiology, endocrinology, gastroenterology, rheumatology, or infectious disease.

Internists are exceptionally well qualified to care for patients with complex conditions or multi-system diseases. Often, other physicians call on internists to act as consultants to help solve puzzling diagnostic problems. As a result, internists earned the name the “doctor’s doctor” since they are a reliable consultant.

Internists also practice in a variety of settings, including private practices, clinics, and hospitals. They also conduct research, teach in medical schools and residency programs, and hold administrative positions in a medical, corporate, or government settings.

The medical profession recognizes internists as pioneers in medicine. They have contributed important milestones in the evolution of patient care and advancements in research, diagnosis, care, and treatment. Notable internists include Nobel Prize winners and other internal medicine specialists and subspecialists. Such worthy recognition applied toward advancements as inventing dialysis, developing the first cardiac risk index, cholesterol synthesis, research on peptic ulcer disease, and holding leadership roles at national and federal government institutes, centers, and agencies.
