Drug-eluting coronary stents (DES) are widely used and entail sizeable Medicare hospital expenditures. However, the overall cost impact of DES has not been well quantified. Clear understanding of how new technologies like DES affect healthcare expenditures can provide insight into national trends in healthcare cost growth, of which new technology is presumably the leading driver. New technology may not only increase costs by being more expensive than previous treatments, but also by changing the patterns of care for chronic disease. Accordingly, we sought to assess the overall impact of DES on Medicare expenditures in a nationally-representative cohort of Medicare beneficiaries with coronary artery disease (CAD).
药物洗脱冠状动脉支架(DES)被广泛使用,并且导致医疗保险医院支出大幅增加。然而,DES对总体成本的影响尚未得到充分量化。清楚了解像DES这样的新技术如何影响医疗保健支出,可以洞察医疗保健成本增长的全国趋势,而新技术大概是这一趋势的主要驱动因素。新技术不仅可能因其比先前治疗更昂贵而增加成本,还可能通过改变慢性病护理模式来增加成本。因此,我们试图在全国代表性的患有冠状动脉疾病(CAD)的医疗保险受益人群队列中评估DES对医疗保险支出的总体影响。
