However, observed lower sensitivity and loss to follow-up of self-sampling could reduce programme effectiveness when attenders of clinician-collected sampling switch to self-sampling. We determined the tipping point for effectiveness (based on life years gained [LYG]) of self-sampling and the consequences for costeffectiveness, taking into account waste by comparing full opt-out (no waste) to no opt-out (waste from unused self-sampling kits) . We used the STDSIMMISCAN-Cervix microsimulation model to simulate a population of Dutch women born in 2000 (50% vaccinated [sensitivity analysis: 0–100%], 70% screening attendance [sensitivity analysis: 60–80%]) . Self-sampling deployment strategies (e.g., direct-mail) were varied by the percentage of original attenders switching to self-sampling and the percentage of new attendance from non-attenders. Main outcome measures were LYG and cost-effectiveness (cost per quality adjusted [QA] LY gained) compared to the current programme. We found that if self-sampling does not reach non-attenders, life years cannot be gained. When reaching 10% or 30% of non-attenders, the tipping point lies at ≤40% and ≤100% switchers to maintain effectiveness, respectively (+4 LYG, +10 LYG) . Scenarios were cost-effective (\u003C€50,000/ QALY gained) if at least 10% of non-attenders were reached. Full opt-out improved cost-effectiveness substantially. So, in a partly vaccinated population, self-sampling deployment strategies need to reach at least 10% of non-attenders to maintain programme effectiveness and cost-effectiveness. A well-functioning opt-out system further improves cost-effectiveness by preventing waste.  \nKEYWOR DS  \ncost-effectiveness, hrHPV, self-sampling, vaccination  \nAbbreviations: ASC-US, atypical squamous cells of undetermined significance; CIN, cervical intraepithelial neoplasia; FIGO, International Federation of Gynecology and Obstetrics; hrHPV, high-risk Human Papillomavirus; LTFU, loss to follow-up; LYG, life years gained; MISCAN, microsimulation screening analysis; QALY, quality adjusted life year; STDSIM, sexually transmitted disease simulation.  \nWe have presented preliminary results of this study at a conference (SMDM Annual North American Meeting 2022) .  \nThis is an open access article under the terms of the Creative Commons Attribution-NonCommercial License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited and is not used for commercial purposes.  \n© 2025 The Author(s) .
