目的:为我国卫生决策部门科学、合理地制定老年人接种23价肺炎球菌多糖疫苗(PPV-23)政策提供理论支持.方法:计算机检索中国期刊全文数据库、万方数据库、Elsevier、PubMed,筛选出老年人接种PPV-23的药物经济学评价的相关文献,分别从成本研究、效果指标、年龄等方面进行统计分析.结果:共纳入13篇文献,合计900 472例老年人,年龄均大于60岁.研究所在地为哥伦比亚、美国、意大利、比利时、荷兰及中国.从成本角度来看,每增加一个生存质量调查年(QALY)成本介于9 239~33 000美元之间;从效果指标来看,成本-效果比介于9 239~45 161美元/AQLY之间.除荷兰一项研究认为65岁以上老年人接种PPV-23不具有成本效益,应该再考虑外,其余研究均显示65岁以上老年人接种PPV-23有一定的成本效益.结论:老年人接种PPV-23具有一定的经济性,且多数国家已将其纳入国家免疫计划.我国现有的研究尚无法确定老年人接种PPV-23的经济性,因此有待开展更多、更高质量的相关研究加以确认.%OBJECTIVE:To provide theoretical support for the scientific and reasonable policy-making of 23-valent pneumococ-cal polysaccharide vaccine(PPV-23)in elderly. METHODS:Retrieved from CJFD,Wanfang Database,Elsevier and PubMed,lit-erature about the pharmacoeconomics evaluation of PPV-23 in elder were selected and statistically analyzed in respects of cost stud-ies,effect indexes and research perspectives. RESULTS:Totally 13 literatures were included,involving 900 472 patients,who were older than 60 years old. Study locations were mainly Colombia,the United States,Italy,Belgium and China. Study results showed,each additional quality-adjusted life-year(QALY)cost was between $ 9 239-$ 33 000 in respect of cost;cost-effectiveness ratio was between $ 9 239-$ 45 161/QALY in respect of effect indexes. Most researches showed PPV-23 in elderly older than 65 years old had certain cast-effectiveness. Only a research in Netherlands held the idea that PPV-23 in elderly was not considered cost-effectiveness.CONCLUSIONS:Putting PPV-23 inelderly has certain cost-effecctiveness and most countries has put it into nation-al immunization program. The present researches can't ensure the economy of putting ppv-23 in elderly in china,so it needs more researches with high quality to ensure it.
