This study examined the effect of a managed-care demonstration program on use of health services by a dually eligible elderly population. Our analysis of utilization data generated from a survey of Medicaid-Medicare beneficiaries in two California counties revealed that utilization behavior of the two study groups did not differ significantly, with two exceptions. The beneficiaries in the demonstration group made more frequent visits to community health clinics and had longer stays in hospitals for medical procedures than did those in the comparison group. In modeling the determinants of health services use, we found that the relationship between ambulatory physician visits and hospitalization of the elderly was complementary rather than substitutive.
本研究考察了一项管理式医疗示范项目对双重资格老年人群体医疗服务使用情况的影响。我们对加利福尼亚州两个县的医疗补助-医疗保险受益人的调查所产生的利用数据进行分析后发现，两个研究组的利用行为没有显著差异，但有两个例外。示范组的受益人比对照组的受益人更频繁地前往社区健康诊所就诊，并且因医疗程序住院的时间更长。在对医疗服务使用的决定因素进行建模时，我们发现老年门诊就诊与住院之间的关系是互补的，而非替代的。
