This article is based on 4 years of data for a cohort of Medicaid enrollees in California and Georgia to determine patterns of enrollment and expenditures. The analyses were developed from the statistical system known as Tape-to-Tape, which is based on Medicaid enrollment and claims files from these and other States. The composition of the cohort changed over times as a result of the differential rates of turnover for subgroups of the Medicaid population. Longitudinal expenditure patterns also varied by health service and eligibility group. These Medicaid expenditure patterns differed from those observed previously in Medicare studies, undoubtedly reflecting differences in service coverage under Medicare and Medicaid.
本文基于加利福尼亚州和佐治亚州医疗补助计划参保人群4年的数据，以确定参保模式和支出情况。这些分析是基于一种名为“磁带对磁带”的统计系统开展的，该系统基于这些州和其他州的医疗补助计划参保及理赔档案。由于医疗补助人群各亚组的更替率不同，该队列的构成随时间发生了变化。纵向支出模式也因医疗服务和资格组而异。这些医疗补助支出模式与之前在医疗保险研究中观察到的模式不同，无疑反映了医疗保险和医疗补助计划在服务覆盖范围上的差异。
