          摘   要  目的  探究医保目录调整对医院罕见病用药的影响,为提高我国罕见病患者用药保障水平提供参考。方法  从全国医药
          经济信息网中提取2016年1月-2018年12月有连续数据的789家医疗机构的罕见病用药的月度采购数据,采用单组间断时间序
          列模型对医保目录调整前后的罕见病用药品种、采购金额、平均限定日费用(DDDc)和用药频度(DDDs)进行比较。结果  2017年
          医保目录共新增9个罕见病用药,包括吡非尼酮、左旋多巴/卡比多巴、利鲁唑、罗匹尼罗、屈昔多巴、依折麦布、依维莫司、重组人凝
          血因子Ⅸ和重组人凝血因子Ⅶa。医保目录调整后,9个罕见病用药的平均DDDc显著降低,DDDs和采购金额的上升趋势显著增
          大(P<0.001)。结论  我国医保目录中新增的罕见病用药数量不断增多,医疗保障覆盖范围不断扩大,罕见病用药价格显著降低,
          患者经济负担进一步降低,罕见病用药的用量显著增加,惠及了更多的罕见病患者,但同时也会增加医院的罕见病用药的采购金
          额。国家医疗保障部门需要充分考虑如何权衡医保基金承受能力与罕见病用药覆盖需求。

          ABSTRACT    OBJECTIVE To explore the impact of the adjustment of the national reimbursement drug list on rare disease drugs
          in  hospitals,  and  to  provide  reference  for  improving  the  drug  security  of  patients  with  rare  diseases  in  China. METHODS  The
          monthly procurement data of rare disease drugs from 789 medical institutions that continuously reported data from January 2016 to
          December  2018  were  extracted  from  the  Chinese  Medicine  Economic  Information.  The  single-group  interrupted  time  series  model
          was used to compare drug varieties, procurement amount, average defined daily cost (DDDc) and defined daily doses (DDDs) of
          rare disease drugs before and after the adjustment of national reimbursement drug list. RESULTS In 2017, a total of 9 rare disease
          drugs were newly included in the national reimbursement drug list, including pirfenidone, carbidopa/levodopa, riluzole, ropinirole,
          droxidopa, ezetimibe, everolimus, coagulation factor Ⅸ human recombinant and coagulation factor Ⅶa human recombinant. After
          the adjustment of the national reimbursement drug list, the average DDDc of 9 rare disease drugs was significantly decreased, the
          upward  trend  of  DDDs  and  the  procurement  amount  was  significantly  increased (P<0.001).  CONCLUSIONS  The  number  of
          newly  included  rare  disease  drugs  in  national  reimbursement  drug  list  keeps  increasing,  the  coverage  of  medical  security  keeps
          expanding, the price of rare disease drugs is significantly decreased, the economic burden of patients is further decreased, and the
          consumption  of  rare  disease  drugs  is  significantly  increased,  benefiting  more  patients  with  rare  diseases;  but  at  the  same  time,  it
          also  increases  the  procurement  amount  of  rare  disease  drugs  in  hospitals.  National  medical  security  departments  need  to  fully
          consider how to balance the affordability of medical insurance funds with the demand for rare disease drug coverage.
