To inform proposed changes in hepatitis C virus (HCV) screening guidelines in the United States, we assessed the cost-effectiveness of HCV antenatal rescreening for women without evidence of HCV during a prior pregnancy, using a previously published model. Universal HCV rescreening among pregnant women was cost-effective (incremental cost-effectiveness ratio, $6000 per quality-adjusted life-year) and should be recommended nationally. ...[more]

Project description:BACKGROUND:Hepatitis C virus' (HCV) chronic prevalence among pregnant women in the United States doubled nationally from 2009-2014 (~0.7%), yet many cases remain undiagnosed. Screening pregnant women is not recommended by the Society of Maternal-Fetal Medicine or the Centers for Disease Control and Prevention, despite new American Association For the Study of Liver Diseases (AASLD)/Infectious Diseases Society of America (IDSA) guidelines recommending screening for this group. We assessed the cost-effectiveness of HCV screening for pregnant women in the United States. METHODS:An HCV natural history Markov model was used to evaluate the cost-effectiveness of universal HCV screening of pregnant women, followed by treatment after pregnancy, compared to background risk-based screening from a health-care payer perspective. We assumed a HCV chronic prevalence of 0.73% among pregnant women, based on national data. We assumed no Medicaid reimbursement restrictions by fibrosis stage at baseline, but explored differing restrictions in sensitivity analyses. We assessed costs (in US dollars) and health outcomes (in quality-adjusted life-years [QALYs]) over a lifetime horizon, using new HCV drug costs of $25 000/treatment. We assessed mean incremental cost-effectiveness ratios (ICERs) under a willingness-to-pay threshold of $50 000/QALY gained. We additionally evaluated the potential population impact. RESULTS:Universal antenatal screening was cost-effective in all treatment eligibility scenarios (mean ICER <$3000/QALY gained). Screening remained cost-effective at a prevalence of 0.07%, which is the lowest estimated prevalence in the United States (in Hawaii). Screening the ~5.04 million pregnant women in 2018 could result in the detection and treatment of 33 000 women, based on current fibrosis restrictions. CONCLUSIONS:Universal screening for HCV among pregnant women in the United States is cost-effective and should be recommended nationally.

Project description:The study was conducted to estimate the relative cost effectiveness of contraceptives in the United States from a payer's perspective.A Markov model was constructed to simulate costs for 16 contraceptive methods and no method over a 5-year period. Failure rates, adverse event rates and resource utilization were derived from the literature. Sensitivity analyses were performed on costs and failure rates.Any contraceptive method is superior to "no method". The three least expensive methods were the copper-T intrauterine device (IUD) (US$647), vasectomy (US$713) and levonorgestrel (LNG)-20 intrauterine system (IUS) (US$930). Results were sensitive to the cost of contraceptive methods, the cost of an unintended pregnancy and plan disenrollment rates.The copper-T IUD, vasectomy and the LNG-20 IUS are the most cost-effective contraceptive methods available in the United States. Differences in method costs, the cost of an unintended pregnancy and time horizon are influential factors that determine the overall value of a contraceptive method.

Project description:BackgroundHepatitis B virus (HBV) continues to cause significant morbidity and mortality in the United States. Current guidelines suggest screening populations with a prevalence of ≥2%. Our objective was to determine whether this screening threshold is cost-effective and whether screening lower-prevalence populations might also be cost-effective.MethodsWe developed a Markov state transition model to examine screening of asymptomatic outpatients in the United States. The base case was a 35-year-old man living in a region with an HBV infection prevalence of 2%. Interventions (versus no screening) included screening for Hepatitis B surface antigen followed by treatment of appropriate patients with (1) pegylated interferon-α2a for 48 weeks, (2) a low-cost nucleoside or nucleotide agent with a high rate of developing viral resistance for 48 weeks, (3) prolonged treatment with low-cost, high-resistance nucleoside or nucleotide, or (4) prolonged treatment with a high-cost nucleoside or nucleotide with a low rate of developing viral resistance. Effectiveness was measured in quality-adjusted life years (QALYs) and costs in 2008 US dollars.ResultsScreening followed by treatment with a low-cost, high-resistance nucleoside or nucleotide was cost-effective ($29,230 per QALY). Sensitivity analyses revealed that screening costs <$50,000 per QALY in extremely low-risk populations unless the prevalence of chronic HBV infection is <.3%.ConclusionsThe 2% threshold for prevalence of chronic HBV infection in current Centers for Disease Control and Prevention/US Public Health Service screening guidelines is cost-effective. Furthermore, screening of adults in the United States in lower-prevalence populations (eg, as low as .3%) also is likely to be cost-effective, suggesting that current health policy should be reconsidered.

Project description:Hepatitis A virus can cause severe and prolonged illness in persons with HIV (PWH). In July 2020, the Advisory Committee on Immunization Practices (ACIP) expanded its recommendation for hepatitis A vaccination to include all PWH aged ≥1 year. We used a decision analytic model to estimate the value of vaccinating a cohort of adult PWH aged ≥20 years with diagnosed HIV in the United States using a limited societal perspective. The model compared 3 scenarios over an analytic horizon of 1 year: no vaccination, current vaccine coverage, and full vaccination. We incorporated the direct medical costs and nonmedical costs (i.e., public health costs and productivity loss). We estimated the total number of infections averted, cost to vaccinate, and incremental cost per case averted. Full implementation of the ACIP recommendation resulted in 775 to 812 fewer adult cases of hepatitis A in 1 year compared with the observed vaccination coverage. The incremental cost-effectiveness ratio for the full vaccination scenario was $48,000 for the 2-dose single-antigen hepatitis A vaccine and $130,000 for the 3-dose combination hepatitis A and hepatitis B vaccine per case averted, compared with the observed vaccination scenario. Depending on type of vaccine, full hepatitis A vaccination of PWH could lead to ≥80% reduction in the number of cases and $48,000 to $130,000 in additional cost per case averted. Data on hepatitis A health outcomes and costs specific to PWH are needed to better understand the longer-term costs and benefits of the 2020 ACIP recommendation.

Project description:BackgroundPregnant women and infants are at increased risk of severe disease from influenza. Antenatal influenza vaccination is safe and can reduce the risk of illness for women and their infants. We evaluated for South Africa the health effects of antenatal influenza vaccination among pregnant women and their infants aged <6 months old and assessed its cost-effectiveness.MethodsWe constructed a decision tree model to simulate the population of pregnant women and infants aged <6 months in South Africa using TreeAge Pro Suite 2015. The model evaluated the change in societal costs and outcomes associated with a vaccination campaign that prioritized HIV-infected over HIV-uninfected pregnant women compared with no vaccination. We also examined the impacts of a campaign without prioritization. Upper and lower 90% uncertainty intervals (90% UI) were generated using probabilistic sensitivity analysis on 10000 Monte Carlo simulations. The cost-effectiveness threshold was set to the 2015 per capita gross domestic product of South Africa, US$5724.ResultsAntenatal vaccination with prioritization averted 9070 (90% UI: 7407-11217) total cases of influenza among pregnant women and infants, including 411 (90% UI: 305-546) hospitalizations and 30 (90% UI: 22-40) deaths. This corresponds to an averted fraction of 13.5% (90% UI: 9.0-20.5%). Vaccinating without prioritization averted 7801 (90% UI: 6465-9527) cases of influenza, including 335 (90% UI: 254-440) hospitalizations and 24 (90% UI: 18-31) deaths. This corresponds to an averted fraction of 11.6% (90% UI: 7.8-17.4%). Vaccinating the cohort of pregnant women with prioritization had societal cost of $4689 (90% UI: $3128-$7294) per Quality Adjusted Life Year (QALY) gained while vaccinating without prioritization had a cost of $5924 (90% UI: $3992-$9056) per QALY.ConclusionsAntenatal influenza vaccination campaigns in South Africa would reduce the impact of influenza and could be cost-effective.

Project description:BackgroundThe prevalence of diagnosed chronic hepatitis C virus (HCV) infection among pregnant women in the Netherlands is 0.26%, yet many cases remain undiagnosed. HCV screening and treatment of pregnant HCV carriers could reduce the burden of disease and limit vertical transmission from mother to child. We assessed the impact of HCV screening and subsequent treatment with new direct-acting antivirals (DAAs) among pregnant women in the Netherlands.MethodsAn HCV natural history Markov transition state model was developed, to evaluate the public-health and economic impact of HCV screening and treatment. Besides all 179,000 pregnant women in the Netherlands (cohort 1), we modelled 3 further cohorts: all 79,000 first-time pregnant women (cohort 2), 33,000 pregnant migrant women (cohort 3) and 16,000 first-time pregnant migrant women (cohort 4). Each cohort was analyzed in various scenarios: i no intervention, i.e., the current practice, ii screen-and-treat, i.e., the most extensive approach involving treatment of all individuals found HCV-positive, and iii screen-and-treat/monitor, i.e., a strategy involving treatment of symptomatic (F1-F4) patients and follow-up of asymptomatic (F0) HCV carriers with subsequent treatment only at progression.ResultsFor all cohorts, comparison between scenarios (ii) and (i) resulted in ICERs between €9,306 and €10,173 per QALY gained and 5 year budget impacts varying between €6,283,830 and €19,220,405. For all cohorts, comparison between scenarios (iii) and (i) resulted in ICERs between €1,739 and €2,749 per QALY gained and budget impacts varying between €1,468,670 and €5,607,556. For all cohorts, the ICERs (scenario iii versus ii) involved in delayed treatment of asymptomatic (F0) HCV carriers varied between €56,607 and €56,892, well above the willingness-to-pay (WTP) threshold of €20,000 per QALY gained and even above a threshold of €50,000 per QALY gained.ConclusionUniversal screening for HCV among all pregnant women in the Netherlands is cost-effective. However, it would be reasonable to consider smaller risk groups in view of the budget impact of the intervention.

Project description:Sofosbuvir and ledipasvir, which have recently been approved for treatment of chronic hepatitis C virus (HCV) infection, are more efficacious and safer than the old standard of care (oSOC) but are substantially more expensive. Whether and in which patients their improved efficacy justifies their increased cost is unclear.To evaluate the cost-effectiveness and budget impact of sofosbuvir and ledipasvir.Microsimulation model of the natural history of HCV infection.Published literature.Treatment-naive and treatment-experienced HCV population defined on the basis of HCV genotype, age, and fibrosis distribution in the United States.Lifetime.Third-party payer.Simulation of sofosbuvir-ledipasvir compared with the oSOC (interferon-based therapies).Quality-adjusted life-years (QALYs), incremental cost-effectiveness ratios (ICERs), and 5-year spending on antiviral drugs.Sofosbuvir-based therapies added 0.56 QALY relative to the oSOC at an ICER of $55 400 per additional QALY. The ICERs ranged from $9700 to $284 300 per QALY depending on the patient's status with respect to treatment history, HCV genotype, and presence of cirrhosis. At a willingness-to-pay threshold of $100 000 per QALY, sofosbuvir-based therapies were cost-effective in 83% of treatment-naive and 81% of treatment-experienced patients. Compared with the oSOC, treating eligible HCV-infected persons in the United States with the new drugs would cost an additional $65 billion in the next 5 years, whereas the resulting cost offsets would be $16 billion.Results were sensitive to drug price, drug efficacy, and quality of life after successful treatment.Data on real-world effectiveness of new antivirals are lacking.Treatment of HCV is cost-effective in most patients, but additional resources and value-based patient prioritization are needed to manage patients with HCV.National Institutes of Health.

Project description:We describe a simplified model, based on the current economic and health effects of human papillomavirus (HPV), to estimate the cost-effectiveness of HPV vaccination of 12-year-old girls in the United States. Under base-case parameter values, the estimated cost per quality-adjusted life year gained by vaccination in the context of current cervical cancer screening practices in the United States ranged from $3,906 to $14,723 (2005 US dollars), depending on factors such as whether herd immunity effects were assumed; the types of HPV targeted by the vaccine; and whether the benefits of preventing anal, vaginal, vulvar, and oropharyngeal cancers were included. The results of our simplified model were consistent with published studies based on more complex models when key assumptions were similar. This consistency is reassuring because models of varying complexity will be essential tools for policy makers in the development of optimal HPV vaccination strategies.

Project description:We surveyed pregnant women from the United States to assess the prevention practices they used when traveling to countries with ongoing Zika virus (ZIKV) outbreaks. Of the 749 who agreed to participate, 710 completed the survey's travel questions and 59 of those had traveled to a ZIKV outbreak area in the past 12 months. Only 43% of the women who had traveled to ZIKV outbreak areas reported frequently using mosquito repellant with 32% stating they did not use it at all. They also did not frequently use other recommended methods to prevent mosquito bites. With the established risks to babies born to women who contract the ZIKV during pregnancy, it is a great concern that a large number of women who travel to outbreak areas during pregnancy are not protecting themselves against mosquito bites. Pregnant women need to be educated on the importance of taking precautions.

Project description:Backgrounds and aimsPregnant women and children are not included in Egypt's hepatitis C virus (HCV) elimination programmes. This study assesses the cost-effectiveness of several screening and treatment strategies for pregnant women and infants in Egypt.DesignA Markov model was developed to simulate the cascade of care and HCV disease progression among pregnant women and their infants according to different screening and treatment strategies, which included: targeted versus universal antenatal screening; treatment of women in pregnancy or deferred till after breast feeding; treatment of infected children at 3 years vs 12 years. Current practice is targeted antenatal screening with deferred treatment for the mother and child. We also explored prophylactic treatment after birth for children of diagnosed HCV-infected women. Discounted lifetime cost, life expectancy (LE) and disability-adjusted life-years (DALYs) were calculated separately for women and their infants, and then combined.ResultsCurrent practice led to the highest cost (US$314.0), the lowest LE (46.3348 years) and the highest DALYs (0.0512 years) per mother-child pair. Universal screening and treatment during pregnancy followed by treatment of children at 3 years would be less expensive and more effective (cost saving) compared with current practice (US$219.3, 46.3525 and 0.0359 years). Prophylactic treatment at birth for infants born to HCV RNA-positive mothers would also be similarly cost saving, even with treatment uptake as low as 15% (US$218.6, 46.3525 and 0.0359 years). Findings were robust to reasonable changes in parameters.ConclusionUniversal screening and treatment of HCV in pregnancy, with treatment of infected infants at age 3 years is cost saving compared with current practice in the Egyptian setting.
