Department leadership

Inova Fairfax Hospital, which is the flagship hospital for Inova and a major referral center for Northern Virginia and the Washington, DC, metro area, is extremely proud of the depth and diversity of its nearly 800 member and 13-section Department of Medicine. The physicians who form the foundation for this medical community are comprised of experts from our nation's top institutions. These clinicians – with today's cutting-edge technology – treat all patients from around the corner to around the world.

In addition to the sections of cardiology, oncology, pulmonology, critical care, endocrinology, rheumatology, dermatology, allergy and immunology, nephrology, gerontology, gastroenterology, infectious diseases and general internal medicine, the Inova Fairfax Hospital Department of Medicine maintains centers of excellence in cardiovascular disease, chronic lung disease, liver disease and cancer care management.

 

Teaching service faculty

Inova Fairfax Hospitalist Group is board-certified internal medicine physicians who admit and care for patients at Inova Fairfax Hospital. In addition to being excellent clinicians, they also excel in teaching residents and medical students. The group has admitting privileges to the teaching service and also participates in noon conferences, morning report conferences and teaching didactic sessions.

Hospitalists provide medical care to hospitalized patients. While the hospitalist program does not replace specialty physicians such as cardiologists and gastroenterologists, it ensures a physician is present in the hospital to see patients throughout the day, meet with families and assist with prescriptions and discharge planning.

Once patients are discharged, the hospitalist sends documentation to the primary care physician about the patient's hospitalization.
