Medical Critical Care Service (MCCS)

The Medical Critical Care Service (MCCS) is comprised of board-certified and hospital-employed critical care physicians, physician assistants and nurse practitioners who are dedicated to the academic mission at Inova Fairfax Hospital. The critical care physicians, also known as intensivists, conduct combined management and teaching rounds every day and serve as the attending of record for the majority of patients on the teaching service. These intensivists also administer the ICU house staff lecture series. The educational director for the rotation is a member of this group and attends monthly Inova Fairfax Hospital Department of Medicine academic meetings to ensure an outstanding experience for the house staff during the rotation.
