What is the difference between an attending physician and an admitting physician.?

Residency is a stage of graduate medical training. A resident physician or resident (also called a house officer / senior house officer in the United Kingdom and several Commonwealth countries) is a person who has received a medical degree (MD, DO, MBBS, MBChB) and who practices medicine under the supervision of fully licensed physicians, usually in a hospital or clinic.

In the United States, an attending physician (also known as an attending, or staff physician) is a physician who has completed residency and practices medicine in a clinic or hospital, in the specialty learned during residency. An attending physician can supervise fellows, residents and medical students. Attending physicians may also have an academic title at an affiliated university such as "professor"
