Background: In the Netherlands, low cervical cancer incidence and mortality rates might limit the cost-effectiveness of vaccination against the human papillomavirus (HPV). We examined the effect on cervical cancer incidence and mortality of adding HPV vaccination to the current Dutch cervical cancer screening situation and calculated the cost-effectiveness.
Methods: Costs and effects were estimated under favorable assumptions (ie, that HPV vaccination provides lifelong protection against 70% of all cervical cancers, has no side effects, and is administered to all women regardless of their risk of cervical cancer) by using the microsimulation screening analysis (MISCAN) model. The impact of changes in the price of vaccination, number of booster vaccinations, vaccination attendance rate, vaccination efficacy, cervical cancer incidence level, and quality-of-life assumptions was investigated in sensitivity analyses.
Results: Using the current price of
118 per vaccine dose and with discounting of costs and effects at an annual rate of 3%, adding HPV vaccination to the current Dutch screening situation had a cost-effectiveness ratio of
53 500 per quality-adjusted life-year (QALY) gained. The threshold price per vaccine dose at which the cost-effectiveness of vaccination would correspond to an acceptability threshold of
20 000 per QALY gained was
40. With the addition of one or more (up to four) booster vaccinations during a lifetime, this threshold price decreased to
33 for one booster (to
16 for four boosters). With a doubling of the cervical cancer incidence level, the cost-effectiveness ratio was
24 400 per QALY gained and the maximum price per dose at threshold of
20 000 was
97. All threshold prices were lower under less favorable effectiveness assumptions.
Conclusions: In the Netherlands, HPV vaccination is not cost-effective even under favorable assumptions. To become cost-effective, the vaccine price would have to be decreased considerably, depending on the effectiveness of the vaccine.
| CONTEXT AND CAVEATS Prior knowledge Cervical cancer incidence and mortality rates in the Netherlands are low, which could limit the cost-effectiveness of human papillomavirus (HPV) vaccination. Study design A simulation model was used to estimate costs and effects of adding HPV vaccination to the current screening situation in the Netherlands and to examine the impact of changes in the price of vaccination, number of booster vaccinations, vaccination attendance rate, vaccination efficacy, cervical cancer incidence level, and quality-of-life assumptions on the cost-effectiveness of HPV vaccination. Contribution HPV vaccination is not cost-effective, even under favorable assumptions, in the Netherlands. Implications To become cost-effective, the vaccine price would have to be decreased considerably, depending on the long-term effectiveness of the vaccine. Limitations The impact of herd (or community) immunity was underestimated because viral transmission was not included in the model. The impact of vaccination on other HPV-related diseases was not taken into account. From the Editors
