Using program administrative data, this paper examines spending and service use patterns for the national Medicaid population between 2002 and 2004, with a focus on high-cost beneficiaries. We observed a high degree of spending persistence. 57.9% of those who were among the top 10% of Medicaid spenders in 2002 remained in the top 10% of spenders in the two subsequent years. We identified two distinct subgroups of high spenders--those with persistently high costs and those with episodically high costs-each with different services driving their costs.
本文利用项目管理数据，研究了2002年至2004年全国医疗补助计划受益人群的支出和服务使用模式，重点关注高成本受益人群。我们观察到支出具有高度持续性。2002年医疗补助支出最高的10%人群中，有57.9%在随后两年仍处于支出最高的10%人群中。我们识别出了两个不同的高支出亚组——成本持续高昂的人群和成本偶尔高昂的人群——每组人群成本增长的驱动服务各不相同。
