Cost-Utility Analysis of Human Papillomavirus Vaccination and Cervical Screening on Cervical Cancer Patient in Indonesia.

BACKGROUND: Although cervical cancer is a preventable disease, the clinical and economic burdens of cervical cancer are still substantial issues in Indonesia. OBJECTIVES: The main purpose of this study was to model the costs, clinical benefits, and cost-utility of both visual inspection with acetic acid (VIA) screening alone and human papillomavirus (HPV) vaccination in addition to VIA screening in Indonesia. METHODS: We developed a population-based Markov model, consisting of three health states (susceptible, cervical cancer, and death), to assess future costs, health effects, and the cost-utility of cervical cancer prevention strategies in Indonesia. We followed a cohort of 100,000 females 12 to 100 years old and compared VIA screening alone with the addition of HPV vaccination on top of the screening to "no intervention." RESULTS: The implementation of VIA screening alone and in combination with HPV vaccination would reduce the cervical cancer incidence by 7.9% and 58.5%, corresponding to 25 and 98 deaths avoided within the cohort of 100,000, respectively. We also estimated that HPV vaccination combined with VIA screening apparently yielded a lower incremental cost-effectiveness ratio at international dollar 1863/quality-adjusted life-year (QALY), compared with VIA screening alone (I$3126/QALY). Both strategies could however be definitely labeled as very cost-effective interventions, based on a threshold suggested by the World Health Organization. The incremental cost-effectiveness ratio was sensitive to the discount rate, cervical cancer treatment costs, and quality of life as part of the QALY. CONCLUSIONS: The addition of HPV vaccination on top of VIA screening could be a cost-effective strategy in Indonesia even if relatively conservative assumptions are applied. This population-based model can be considered as an essential tool to inform decision makers on designing optimal strategies for cervical cancer prevention in Indonesia.

The cost-effectiveness of HPV vaccination in addition to screening: a Dutch perspective.

Addition of the HPV vaccine to available cytological screening has been proposed to increase HPV-related cancer prevention. A comprehensive review on this combined strategy implemented in the Netherlands is lacking. For this review, we therefore analyzed all relevant studies on cost-effectiveness of HPV vaccines in combination with cervical screening in the Netherlands. Most of the studies agree that vaccination in pre-sexual-activity periods of life is cost-effective. Based on published sensitivity analyses, the incremental cost-effectiveness ratio was found to be mainly driven by vaccine cost and discount rates. Fewer vaccine doses, inclusion of additional benefits of these vaccines to prevent HPV-related non-cervical cancers and vaccination of males to further reduce the burden of HPV-induced cancers are three relevant options suggested to be investigated in upcoming economic evaluations.
