A vaccine to prevent diseases due to human papillomavirus (HPV) types 6, 11, 16, and 18 is now available in France. The objective of this study was to assess the health and economic impact in France of implementing a quadrivalent HPV vaccine alongside existing screening practices versus screening alone.
A Markov model of the natural history of HPV infection incorporating screening and vaccination, was adapted to the French context. A vaccine that would prevent 100 percent of HPV 6, 11, 16, and 18-associated diseases, with lifetime duration and 80 percent coverage, given to girls at age 14 in conjunction with current screening was compared with screening alone. Results were analyzed from both a direct healthcare cost perspective (DCP) and a third-party payer perspective (TPP). Indirect costs such as productivity loss were not taken into account in this analysis.
The incremental cost per life-year gained from vaccination was euro12,429 (TPP) and euro20,455 (DCP). The incremental cost per quality-adjusted life-year (QALY) for the introduction of HPV vaccination alongside the French cervical cancer screening program was euro8,408 (TPP) and euro13,809 (DCP). Sensitivity analyses demonstrated that cost-effectiveness was stable, but was most sensitive to the discount rate used for costs and benefits.
Considering the commonly accepted threshold of euro50,000 per QALY, these analyses support the fact that adding a quadrivalent HPV vaccine to the current screening program in France is a cost-effective strategy for reducing the burden of cervical cancer, precancerous lesions, and genital warts caused by HPV types 6, 11, 16, and 18.
法国现已可获得一种预防由人乳头瘤病毒(HPV)6、11、16和18型引起疾病的疫苗。本研究的目的是评估在法国实施四价HPV疫苗并结合现有筛查措施与仅进行筛查相比,对健康和经济的影响。
将一个纳入筛查和疫苗接种的HPV感染自然史马尔可夫模型应用于法国情况。将一种能预防100%HPV 6、11、16和18型相关疾病、具有终身效力且覆盖率为80%、在14岁女孩中接种并结合当前筛查的疫苗与仅进行筛查相比较。从直接医疗成本视角(DCP)和第三方支付者视角(TPP)对结果进行分析。本分析未考虑如生产力损失等间接成本。
接种疫苗每获得一个生命年的增量成本为12,429欧元(TPP)和20,455欧元(DCP)。在法国宫颈癌筛查项目中引入HPV疫苗接种每获得一个质量调整生命年(QALY)的增量成本为8,408欧元(TPP)和13,809欧元(DCP)。敏感性分析表明成本效益是稳定的,但对用于成本和效益的贴现率最为敏感。
考虑到每QALY普遍接受的50,000欧元阈值,这些分析支持在法国当前筛查项目中添加四价HPV疫苗是一种具有成本效益的策略,可减轻由HPV 6、11、16和18型引起的宫颈癌、癌前病变和尖锐湿疣负担这一事实。
