ARTICLE ABSTRACT

We evaluate the cost-effectiveness of human papillomavirus (HPV) self-collection (followed by scheduling assistance for those who were HPV+ or inconclusive) compared with scheduling assistance only and usual care among underscreened persons with a cervix (PWAC). A decision tree analysis was used to estimate the incremental cost-effectiveness ratios (ICER), or the cost per additional PWAC screened, from the Medicaid/state and clinic perspectives. A hypothetical cohort represented 90,807 low-income, underscreened individuals. Costs and health outcomes were derived from the MyBodyMyTest-3 randomized trial except the usual care health outcomes were derived from literature. We performed probabilistic sensitivity analyses (PSA) to evaluate model uncertainty. Screening uptake was highest in the self-collection alternative (n = 65,721), followed by the scheduling assistance alternative (n = 34,003) and usual care (n = 18,161). The self-collection alternative costs less and was more effective than the scheduling assistance alternative from the Medicaid/state perspective. Comparing the self-collection alternative with usual care, the ICERs were $284 per additional PWAC screened from the Medicaid/state perspective and $298 per additional PWAC screened from the clinic perspective. PSAs demonstrated that the self-collection alternative was cost-effective compared with usual care at a willingness-to-pay threshold of $300 per additional PWAC screened in 66% of simulations from the Medicaid/state perspective and 58% of simulations from the clinic perspective. Compared with usual care and scheduling assistance, mailing HPV self-collection kits to underscreened individuals appears to be cost-effective in increasing screening uptake. This is the first analysis to demonstrate the cost-effectiveness of mailed self-collection in the United States.
