What is "nocturnist"

n. A hospitalist who works only night shifts.

A nocturnist is a hospital-based physician who only works overnight. Most nocturnists are trained in internal medicine or family medicine and have experience in hospital medicine. However, there are nocturnists trained in other specialties, such as pediatrics. The main role of a nocturnist is to admit patients into the hospital from an emergency room, and to care for previously admitted inpatients through the night.
