IntroductionCervical cancer screening and existing health insurance schemes in China fall short of reaching women with prevention and treatment services, especially in rural areas where the disease burden is greatest. We conducted an extended cost-effectiveness analysis (ECEA) to evaluate public financing of HPV vaccination to prevent cervical cancer, adding new dimensions to conventional cost-effectiveness analysis through an explicit inclusion of equity and impact on financial risk protection.MethodsWe synthesized available epidemiological, clinical, and economic data from China using an individual-based Monte Carlo simulation model of cervical cancer to estimate the distribution of deaths averted by income quintile, comparing vaccination plus screening against current practice. We also estimated reductions in cervical cancer incidence, net costs to the government (HPV vaccination costs minus cervical cancer treatment costs averted), and patient cost savings, as well as the incremental government health care costs per death averted.ResultsHPV vaccination is cost-effective across all income groups when the cost is less than US $50 per vaccinated girl. Compared to screening alone, adding preadolescent HPV vaccination followed by cervical cancer screening in adulthood could reduce cancer by 44 percent across all income groups, while providing relatively higher financial protection to the poorest women. The absolute numbers of cervical cancer deaths averted and the financial risk protection from HPV vaccination are highest among women in the lowest quintile; women in the bottom income quintiles received higher benefits than those in the upper wealth quintiles. Patient cost savings represent a large proportion of poor women's average per capita income, reaching 60 percent among women in the bottom income quintile and declining to 15 percent among women in the wealthiest quintile.Copyright © 2015 The Authors.
