What is Hospital Medicine?

According to the Society of Hospital Medicine, Hospital Medicine is a medical specialty dedicated to the delivery of comprehensive medical care to hospitalized patients. Practitioners of hospital medicine include physicians (“hospitalists”) and advanced practice clinicians who engage in clinical care, teaching, research, or leadership in the field of general hospital medicine.
