The purpose of this study was to evaluate the prescribing behavior, recipient response, and economic impact of the removal of selected prescription drug products from the Michigan Medicaid formulary. The frequency with which alternate legend drugs were prescribed and the frequency of continuous therapy via out-of-pocket cash were determined. From 17 independent Michigan pharmacies, a total of 137 patients with prescriptions for at least one eliminated drug product was identified. Of the Medicaid recipients on continuous therapy, 46% discontinued therapy. Over 23% had an alternate legend drug prescribed still covered under the Medicaid drug benefit. The alternate drug resulted in significantly higher acquisition costs. Over 30% of the recipients continued therapy at their own expense, representing a cost savings to the Medicaid program.
本研究的目的是评估从密歇根医疗补助药品目录中移除某些处方药产品后的处方行为、接受者反应及经济影响。确定了替代处方药的处方频率以及通过自付现金进行持续治疗的频率。从密歇根州17家独立药房中，共识别出137名至少有一种被淘汰药品处方的患者。在接受持续治疗的医疗补助接受者中，46%停止了治疗。超过23%的患者开具了仍在医疗补助药品福利范围内的替代处方药。替代药物导致采购成本显著更高。超过30%的接受者自费继续治疗，这为医疗补助计划节省了成本。
