The Inter-Institute Endocrinology Training Program (IETP) seeks to train internal medicine physicians to become first-rate endocrinologists dedicated to investigative careers. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), the National Institute of Child Health and Human Development (NICHD), and the National Institute of Dental and Craniofacial Research (NIDCR) participate in the program, with faculty from all three institutes.

Clinical and research training

Clinical training occurs largely in the first year. At any one time, fellows are responsible for five to ten patients on the inpatient service of the NIH. Under the supervision of the endocrine faculty, the trainee has complete responsibility for all aspects of a patient’s care. Fellows make daily rounds, discuss patients with the attending physicians, and participate in management decisions related to both patient care and clinical investigation. Although all patients are admitted under peer-reviewed research protocols, there are many other aspects of diagnosis and patient care that fall entirely under the discretion of the endocrine fellows. During the second and third year, emphasis is placed on learning how to develop research questions, which enables fellows to investigate unusual disorders or particular scientific questions, and on maintaining clinical expertise. Fellows are also encouraged to participate in specific hypothesis-driven protocols.

The second and third year are spent primarily in laboratory or clinical research under the mentorship of a senior investigator in one of the several endocrinology branches of the NIH. During this research period, active clinical experience continues through bi-weekly continuity outpatient clinics (general endocrinology as well as diabetes clinics) and participation in clinical conferences. In addition, fellows on the endocrine service serve as consultants to the other services within the Clinical Center, where patients are not selected with regard to endocrine problems. Thus, fellows gain experience with several common problems of endocrine disease that may occur in any general medical ward. Clinical research activities include programs in all the areas of endocrine and metabolic disease. Study design, outcome measures, statistical analysis, and ethical and regulatory issues are stressed.

The IETP provides a comprehensive training experience that involves not only the NIH clinical branches working in Endocrinology but also the Georgetown University Hospital and Washington Hospital Center, both in the Washington area. The basic and clinical endocrine research facilities at the NIH are among the most extensive and highly regarded in the world. Thus, the fellowship is ideal for physicians who seek a broad education in both research and clinical endocrinology.
