Pregnancy Outcomes in Women With a Prior Cervical Intraepithelial Neoplasia Grade 3 Diagnosis

Treatment of cervical intraepithelial neoplasia grade 3 (CIN 3) removes or destroys part of the cervix and might subsequently influence pregnancy outcomes. To investigate pregnancy outcomes in women diagnosed with CIN 3. Population- and sibling-matched cohort study. Sweden, 1973 to 2018. The general population comparison included 78 450 singletons born to women diagnosed with CIN 3 and 784 500 matched singletons born to women in the general population who had no CIN 3 diagnosis; the sibling comparison included 23 199 singletons born to women diagnosed with CIN 3 and 28 135 singletons born to their sisters without a CIN 3 diagnosis. Preterm birth, including spontaneous or iatrogenic preterm birth; infection-related outcomes, including chorioamnionitis and infant sepsis; and early neonatal death, defined as death during the first week after birth. Compared with the matched general population, women previously diagnosed with CIN 3 were more likely to have a preterm birth, especially extremely preterm (22 to 28 weeks; odds ratio [OR], 3.00 [95% CI, 2.69 to 3.34]) or spontaneous preterm (OR, 2.12 [CI, 2.05 to 2.20]); infection-related outcomes, including chorioamnionitis (OR, 3.23 [CI, 2.89 to 3.62]) and infant sepsis (OR, 1.72 [CI, 1.60 to 1.86]); or early neonatal death (OR, 1.83 [CI, 1.61 to 2.09]). Sibling comparison analyses rendered largely similar results. Over time, the risk difference attenuated for all outcomes and disappeared for early neonatal death. Lack of data on CIN 3 treatment and spontaneous abortion. History of CIN 3 is associated with adverse pregnancy outcomes even after accounting for familial factors. Decreasing risk estimates over time suggest that adverse pregnancy outcomes among women diagnosed with CIN 3 may be minimized by improving treatment methods.

Cost-Effectiveness of Extending Human Papillomavirus Vaccination to Population Subgroups Older Than 26 Years Who Are at Higher Risk for Human Papillomavirus Infection in the United States

In June 2019, the U.S. Advisory Committee on Immunization Practices recommended shared clinical decision making regarding potential human papillomavirus (HPV) vaccination of men and women aged 27 to 45 years ("mid-adults"). To examine the incremental cost-effectiveness ratios (ICERs) and number needed to vaccinate (NNV) to prevent 1 HPV-related cancer case of expanding HPV vaccination to subgroups of mid-adults at increased risk for HPV-related diseases in the United States. Individual-based transmission dynamic modeling of HPV transmission and associated diseases using HPV-ADVISE (Agent-based Dynamic model for VaccInation and Screening Evaluation). Published data. All U.S. mid-adults and higher-risk subgroups within this population. 100 years. Health care sector. Expanding 9-valent HPV vaccination to mid-adults and higher-risk subgroups. ICERs and NNVs. Expanding 9-valent HPV vaccination to all mid-adults, those with more lifetime partners, and those who have just separated was projected to cost an additional $2 005 000, $763 000, and $1 164 000 per quality-adjusted life-year (QALY) gained, respectively. The NNVs to prevent 1 additional HPV-related cancer case were 7670, 3190, and 5150, respectively, compared with 223 for vaccination of persons aged 9 to 26 years (vs. no vaccination). The mid-adult strategy with the lowest ICER and NNV was vaccinating infrequently screened mid-adult women who have just separated and have a higher number of lifetime sex partners (ICER, $86 000 per QALY gained; NNV, 470). Uncertainty about rate of new sex partners and natural history of HPV among mid-adults. Vaccination of mid-adults against HPV is substantially less cost-effective and produces higher NNVs than vaccination of persons younger than 26 years under all scenarios investigated. However, cost-effectiveness and NNV are projected to improve when higher-risk mid-adult subgroups are vaccinated, such as mid-adults with more sex partners and who have recently separated, and women who are underscreened.
