In this article the author reviews the prescription drug coverage policy in the Medicare End Stage Renal Disease (ESRD) program and examines the relationship between secondary insurance status and the number of medications prescribed for dialysis patients who had Medicare as their primary payer. Negative binomial models were used to examine this relationship. Findings in this study indicate that the number of secondary payers has a significant impact on the number of prescription drugs received by Medicare ESRD patients. Further research is needed to determine whether Medicare beneficiaries without secondary insurance are obtaining fewer prescriptions than needed or if those with greater coverage are obtaining more than needed.
在本文中，作者回顾了医疗保险终末期肾病（ESRD）项目中的处方药覆盖政策，并研究了作为主要支付方的医疗保险患者的二级保险状态与为透析患者开具的药物数量之间的关系。使用负二项式模型来研究这种关系。本研究的结果表明，二级支付方的数量对医疗保险ESRD患者接受的处方药数量有重大影响。需要进一步研究以确定没有二级保险的医疗保险受益人所获得的处方是否少于所需，或者保险范围更广的受益人所获得的处方是否多于所需。
