摘 要 目的:对依那普利叶酸片与依那普利片用于高血压患者卒中预防的药物经济性进行评价。方法:使用Excel 2016软件构建马尔可夫模型,选择原发性高血压患者作为研究对象,研究时限为20年,循环周期为1年。从卫生体系角度出发,使用成本-效用分析法对依那普利叶酸片与依那普利片用于高血压患者卒中预防的药物经济性进行比较,并用敏感性分析验证研究结果的稳健性。结果:与依那普利片相比,依那普利叶酸片的增量成本-效果比为221 323.04元/质量调整生命年,大于3倍2020年中国人均国内生产总值(217 341元)。单因素敏感性分析与概率敏感性分析的结果与基础分析的结果一致。结论:对于高血压患者而言,使用依那普利叶酸片预防卒中相较于依那普利片不具有经济性。

ABSTRACT OBJECTIVE: To evaluate the pharmacoeconomics of Enalapril folic acid tablet and Enalapril tablet for stroke prevention in patients with hypertension. METHODS: Markov model was constructed by using Excel 2016 software. Patients with essential hypertension were selected as the research object with 1 year cycle and 20 years horizon. From the perspective of health system, the pharmacoeconomics of Enalapril folic acid tablets versus Enalapril tablets for stroke prevention in patients with hypertension was compared by cost-effectiveness analysis, and the stability of the research results was verified by sensitivity analysis. RESULTS: Compared with Enalapril tablet, the incremental cost-effectiveness ratio of Enalapril folic acid tablet was 221 323 yuan/QALY, which was higher than three times of China’s per capita GDP in 2020 (217 341.04 yuan). The results of single factor sensitivity analysis and probabilistic sensitivity analysis were consistent with that of basic analysis. CONCLUSIONS: Compared with Enalapril tablet, Enalapril folic acid tablet doesn’t have a better economy for patients with hypertension.

卒中是严重危害我国国民健康的重大慢性非传染性疾病,是我国成人致死、致残的首位病因,具有高发病率、高致残率、高病死率、高复发率、高经济负担五大特点[1]。根据“脑卒中高危人群筛查和干预项目”的数据显示,我国40岁及以上人群的卒中标化患病率由2012年的1.89%上升至2018年的2.32%,由此推算2019年我国40岁及以上卒中患者人数达到1 318万[1]。由《2020中国卫生健康统计年鉴》可知,2019年我国农村居民的卒中病死率为158/10万,城市居民的卒中病死率為129/10万,缺血性卒中和出血性卒中患者的人均住院费用分别为 9 809元和20 105元,患者的疾病负担较重[2]。……
