This paper examines how physician fees affect use of physician and hospital services under the Medicaid program. Using data from the 1987 National Medical Expenditure Survey (NMES), it examines how Medicaid physician fee levels affect beneficiaries' probability of using ambulatory physician services, the site at which ambulatory physician care is usually received, and how that site affects level of use and probability of hospital admission. The results indicate that low Medicaid fees hamper access to office-based physicians and encourage use of hospital outpatient departments and emergency rooms. They also indicate that having an office-based doctor as a usual source of ambulatory physician care is associated with a higher frequency of visits and a lower probability of having an inpatient hospitalization.
本文探讨了医师费用如何影响医疗补助计划下医师服务和医院服务的使用情况。利用1987年国家医疗支出调查（NMES）的数据，研究了医疗补助医师费用水平如何影响受益人使用门诊医师服务的概率、通常接受门诊医师护理的地点，以及该地点如何影响使用水平和住院概率。结果表明，较低的医疗补助费用阻碍了患者获得门诊医师服务，并促使他们更多地使用医院门诊部和急诊室。结果还表明，将门诊医师作为通常的护理来源与更高的就诊频率和更低的住院概率相关。
