The purpose of this study was to examine the factors affecting medical expenditure associated with outpatient care provided in physician clinics. Besides patient characteristics, this study examined the effect of provider practice patterns on health expenditure. The study used the outpatient claim data for all Medicaid and health insurance patients of hypertension, gonarthrosis, dorsalgia and diabetes, who received medical services in physician clinics in the first half of 2006. Empirical results showed that outpatient expenditure per care is greater for Medicaid patients, and the age and severity of patients are positively associated with greater medical care expenditure. Provider characteristics, such as the age and length of practice of the physician, ownership of high-tech equipment, competition in the market area, and the severity and age structure of the patient pool, are associated with outpatient expenditure, too.
