Medical Intern
A medical intern is a term used for a physician in training who has completed medical school. An intern in the medical field has an M.D. or D.O. degree but does not have a full license to practice medicine unsupervised in the U.S. They are in their first year of residency. A medical residency gives in-depth training within a specific branch of medicine, such as internal medicine, neurology, psychiatry, physical medicine and rehabilitation, and radiology. The field of surgery also has several specialties such as neurosurgery, orthopaedics, and general surgery.This first internship year is also called “PGY-1,” meaning “post-graduate year 1.” They practice under direct supervision of a senior resident and attending physician. Interns are expected to know nearly everything about the patients assigned to them, and they are the first persons called by nurses. Interns generally write orders for all medications, tests, and consultations.
