药物经济学评估的对照选择

2018-10-17 浮白先生 浮白先生

医药经济学评估是有对照的。在设计研究方案时,就需要确定对照物的选择。设置对照是医学研究的惯例,其原因是生物医学领域中个体差异大,因此需要设置对照组以排除干扰、凸显研究因素(使用哪种医药技术方案)的真正作用。医药经济学评估也是如此,虽然在纯理论化模型模拟中是否需要设置对照还可以商榷,但一般情况下设置对照组都是必要的。 因此,对医药技术进行经济学评估,得到是相比对照物的经济性,是相比对照物价

药物经济学评估技术中的预算影响分析

医药经济学评估是对医药技术的成本和健康产出进行综合分析并优选经济性的学科技术。所谓成本和产出的综合分析,通俗讲就是分析“性价比”,即单位成本投入所能获得的产出。于是在不少人的心目中,医药经济学评估就是“性价比”分析技术。   其实并非如此。在医药经济学评估的论文中,我们还经常会看到另一种分析:预算影响分析,英文为Budget impact analysis,简称BIA。于是问题来

药物经济学评估技术:健康产出

健康产出,是和成本并列的,医药经济学评估技术的两大基本内容之一。合理的界定和测量健康产出,对正确的开展评估至关重要。但是,不同于成本测量的明确性(∑价格*数量),健康产出的指标选择和测量相当复杂,令人纠结。 在经典的经济学评估中,产出与成本一样,都是通过货币指标来衡量的。例如,政府要决策是否修一条高速公路,或者企业要决策是否兴建一个新工厂,从经济角度,都是计算需要投入多少钱、能够产出

速懂:药物经济学中评估模型

药物经济学评估技术中,看上去最有技术含量、也最能唬人的概念,就是评估用的“模型”。模型给人感觉高大上,很深奥的样子。 在传统的医学研究中,无论是临床试验还是流行病学调研,人们都很少强调研究中的模型,最多是在结果的统计分析中用到诸如“一般线性回归模型”等数理统计模型。但在医药经济学评估中,模型则用的很普遍,似乎不建立模型就无法进行经济学评估,这往往使不熟悉该领域的人觉得困惑。  

药物经济学评估结果解读、敏感性分析、评估质量

医药经济学评估是对医药技术的长期成本和健康产出的综合分析,并且我们也说过,医药经济学评估是需要设立对照的比较性研究。那么,这种又长期又综合又对照的、看似颇为复杂的科学研究,其最后的结果指标是怎么样的呢,是简明易懂的、还是晦涩难解的呢? 简单的说,医药经济学评估就是对被研究医药技术和对照技术的成本和健康产出进行计算、然后对两者的差别进行分析。复杂的事情是在成本和健康产出的计算过程中,而如果

如今,我国药物经济学在药物一致性评价、药品定价、医保目录调整、药品谈判等政策领域的应用正在快速增加。

新一轮医药降费窗口正在打开

7月7日,在2018药物经济学的应用与发展座谈会上,中国社会保障学会会长郑功成表示,新一轮医药降费的窗口正在打开,包括有关部委加快境外上市新药的审批节奏、强化短缺药品供应、落实高价药品降价、推动药品创新和仿制、完善医保准入机制和价格谈判机制等,一大批政策措施正在落地。
