This study used national Medicaid data from 1994-2003 to investigate trends in noninstitutional drug utilization and expenditures in the Medicaid Program. We found that there was a substantial increase in both drug utilization and expenditures during this timeframe. Increased utilization resulted from increases in Medicaid enrollment, the mean number of prescriptions per enrollee, mean nominal and inflation-adjusted reimbursement per prescription, and the tendency for increased use of more expensive drugs. The top 40 drugs accounted for nearly $14.4 billion, roughly 43 percent of the total drug reimbursements for calendar year (CY) 2003.

本研究使用了1994年至2003年的国家医疗补助数据，以调查医疗补助计划中非机构药物使用和支出的趋势。我们发现，在此期间药物使用和支出均大幅增加。使用量增加是由于医疗补助参保人数增加、每位参保人的平均处方数、每张处方的平均名义报销额和经通胀调整后的报销额增加，以及使用更昂贵药物的趋势增加。2003年日历年中，排名前40的药物占报销总额近144亿美元，约占药物报销总额的43%。
