In the past, when a patient was admitted to the hospital, that patient’s primary care physician (PCP) would also take care of him or her every day in the hospital. However, it was often difficult for PCPs to see both their regularly scheduled clinic patients as well as their hospitalized patients every day. As a result, hospitals started hiring hospitalists, doctors who take care of patients only while they are in the hospital. These doctors do not see patients in clinics or outpatient offices. In hospitals where there are hospitalists, PCPs usually provide care for their patients only outside of the hospital.
