Outpatient care is defined as any health care services that do not require an overnight hospital stay. Key changes shifting the balance between inpatient and outpatient care include reimbursement policies, technological advances, utilization control factors, and social factors. It is important for hospital administrators to regard outpatient care as a key component of their business strategy because the number of inpatient stays are declining. Outpatient services help reduce costs and the survival of hospitals depends on outpatient care services growing to offset declining inpatient revenues.
