Although much attention has been paid to examining the impact of Medicare Part D on Medicare, few studies have examined its influence on Medicaid. This study uses an interrupted time series design to examine the impact of Part D on prescription drug expenditures and utilization among different therapeutic classes of medication across 44 Medicaid programs. In overall reductions in Medicaid prescription expenditures and utilization, our study finds evidence of greater reductions among medications used to treat chronic conditions. Our results provide a glimpse of the impact of Part D on long-term growth in the Medicaid prescription drug benefit.
尽管人们已经非常关注医疗保险D部分对医疗保险的影响，但很少有研究考察其对医疗补助计划的影响。本研究采用间断时间序列设计，考察D部分对44个医疗补助计划中不同治疗类别的处方药支出和使用情况的影响。在医疗补助计划处方药支出和使用的总体减少方面，我们的研究发现，用于治疗慢性病的药物减少幅度更大。我们的结果初步显示了D部分对医疗补助计划处方药福利长期增长的影响。
