Cytomegalovirus Screening in Pregnancy: A Cost-Effectiveness and Threshold Analysis

Objective To determine threshold cytomegalovirus (CMV) infectious rates and treatment effectiveness to make universal prenatal CMV screening cost-effective. Study Design Decision analysis comparing cost-effectiveness of two strategies for the prevention and treatment of congenital CMV: universal prenatal serum screening and routine, risk-based screening. The base case assumptions were a probability of primary CMV of 1% in seronegative women, hyperimmune globulin (HIG) effectiveness of 0%, and behavioral intervention effectiveness of 85%. Screen-positive women received monthly HIG and screen-negative women received behavioral counseling to decrease CMV seroconversion. The primary outcome was the cost per maternal quality-adjusted life year (QALY) gained with a willingness to pay of $100,000 per QALY. Results In the base case, universal screening is cost-effective, costing $84,773 per maternal QALY gained. In sensitivity analyses, universal screening is cost-effective only at a primary CMV incidence of more than 0.89% and behavioral intervention effectiveness of more than 75%. If HIG is 30% effective, primary CMV incidence can be 0.82% for universal screening to be cost-effective. Conclusion The cost-effectiveness of universal maternal screening for CMV is highly dependent on the incidence of primary CMV in pregnancy. If efficacious, HIG and behavioral counseling allow universal screening to be cost-effective at lower primary CMV rates.

ObjectivesTo assess the cost-effectiveness of universal repeat screening for syphilis in late pregnancy, compared with the current strategy of single screening in early pregnancy with repeat screening offered only to high-risk women.DesignA decision tree model was developed to assess the incremental costs and health benefits of the two screening strategies. The base case analysis considered short-term costs during the pregnancy and the initial weeks after delivery. Deterministic and probabilistic sensitivity analyses and scenario analyses were conducted to assess the robustness of the results.SettingUK antenatal screening programme.PopulationHypothetical cohort of pregnant women who access antenatal care and receive a syphilis screen in 1 year.Primary and secondary outcome measuresThe primary outcome was the cost to avoid one case of congenital syphilis (CS). Secondary outcomes were the cost to avoid one case of intrauterine fetal demise (IUFD) or neonatal death and the number of women needing to be screened/treated to avoid one case of CS, IUFD or neonatal death. The cost per quality-adjusted life year gained was assessed in scenario analyses.ResultsBase case results indicated that for pregnant women in the UK (n=725 891), the repeat screening strategy would result in 5.5 fewer cases of CS (from 8.8 to 3.3), 0.1 fewer cases of neonatal death and 0.3 fewer cases of IUFD annually compared with the single screening strategy. This equates to an additional £1.8 million per case of CS prevented. When lifetime horizon was considered, the incremental cost-effectiveness ratio for the repeat screening strategy was £120 494.ConclusionsUniversal repeat screening for syphilis in pregnancy is unlikely to be cost-effective in the current UK setting where syphilis prevalence is low. Repeat screening may be cost-effective in countries with a higher syphilis incidence in pregnancy, particularly if the cost per screen is low.

Background: A number of new anticoagulants for stroke prevention in atrial fibrillation (SPAF) have gained regulatory approval or are in late-stage development. We sought to conduct a systematic review of economic models of dabigatran, rivaroxaban and apixaban for SPAF. Methods: We searched the Medline, Embase, National Health Service Economic Evaluation Database and Health Technology Assessment database along with the Tuft’s Registry through October 10, 2012. Included models assessed the cost-effectiveness of dabigatran (150mg, 110mg, sequential), rivaroxaban or apixaban for SPAF using a Markov model or discrete event simulation and were published in English. Results: Eighteen models were identified. All models utilized a lone randomized trial (or an indirect comparison utilizing a single study for any given direct comparison), and these trials were clinically and methodologically heterogeneous. Dabigatran 150mg was assessed in 9 of models, dabigatran 110mg in 8, sequential dabigatran in 9, rivaroxaban in 4 and apixaban in 4. Adjusted-dose warfarin (either trial-like, real-world prescribing or genotype-dosed) was a potential first-line therapy in 94% of models. Models were conducted from the perspective of the United States (44%), European countries (39%) and Canada (17%). In base-case analyses, patients typically were at moderate-risk of ischemic stroke, initiated anticoagulation between 65 and 73 years of age, and were followed for or near a lifetime. All models reported cost/quality-adjusted life-year (QALY) gained, and while 22% of models reported using a societal perspective, no model included costs of lost productivity. Four models reported an incremental cost-effectiveness ratio (ICER) for a newer anticoagulant (dabigatran 110mg (n=4)/150mg (n=2); rivaroxaban (n=1)) vs. warfarin above commonly reported willingness-to-pay thresholds. ICERs (in 2012US$) vs. warfarin ranged from $3,547-$86,000 for dabigatran 150mg, $20,713-$150,000 for dabigatran 110mg, $4,084-$21,466 for sequentially-dosed dabigatran and $23,065-$57,470 for rivaroxaban. In addition, apixaban was demonstrated to be an economically dominant strategy compared to aspirin and to be dominant or cost-effective ($11,400-$25,059) vs. warfarin. Based on separate indirect treatment comparison meta-analyses, 3 models compared the cost-effectiveness of these new agents and reported conflicting results. Conclusions: Cost-effectiveness models of newer anticoagulants for SPAF have been extensively published. Models have frequently found newer anticoagulants to be cost-effective, but due to the lack of head-to-head trial comparisons and heterogeneity in clinical characteristic of underlying trials and modeling methods, it is currently unclear which of these newer agents is most cost-effective.

Abstract BACKGROUND The addition of novel therapy “Tumor-Treating fields” (TTF) to standard radio-chemotherapy with Temozolomide (TMZ) has recently shown superiority over conventional TMZ regimen in patients with glioblastoma. Despite the clinical benefit of TTF, there is a strong concern regarding the cost of this new treatment. A first cost-effectiveness analysis, which was published in 2016, was based on effectiveness outcomes from an interim analysis of the pivotal trial and used a “standard” Markov model. Here, we aimed to update the cost-effectiveness evaluation using a partitioned survival model design and using the latest effectiveness data. MATERIAL AND METHODS A partitioned survival model was developed with three mutually exclusive health states: stable disease, progressive disease, and dead. Parametric models were fitted to the Kaplan-Meier data for overall and progression-free survival. These generated clinically plausible extrapolations beyond the observed data. The perspective of the French national health insurance was adopted and the time horizon was 20 years. Base case results were expressed as cost/life-years (LY) gained (LYG). Secondary analyses were undertaken, with the results presented as cost/per quality adjusted life years (QALY) gained. Last, we undertook deterministic and probabilistic sensitivity analyses. RESULTS After applying 4% annual discounting of benefits and costs, the base case model generated incremental benefit of 0.507 LY at a incremental cost of €258,695 yielding an incremental cost effectiveness ratio (ICER) of €510,273 / LYG. Secondary analyses yielded an ICER of €667,173/QALY. Sensitivity analyses and bootstrapping methods showed the model was relatively robust. The model was sensitive to TTF device costs and the parametric model fitted to the Kaplan-Meier data for overall survival. The cost-effectiveness acceptability curve showed TTF has 0% of being cost-effective under conventional thresholds. CONCLUSION Using a partitioned survival model, uprated costs and more mature survival outcomes, TTF when compared to standard radio-chemotherapy with TMZ is not likely to be cost-effective. This has major implications in terms of access of newly eligible patients

272 Background: In addition to a diagnostic laparoscopy (DL), aroutine laparoscopic ultrasound (LUS) has been proposed to identify undetected hepatic metastases and/or anatomically advanced disease in patients with T2 or higher gall bladder cancer (GBC) planned for surgical resection. It was hypothesized that a routine LUS is not a cost-effective strategy for these patients. Methods: Decision tree modeling was undertaken to compare DL-LUS vs. DL at the time of definitive resection of GBC (with no prior cholecystectomy). Costs in US dollars (payers’ perspective), quality-adjusted-life-weeks (QALWs) and incremental-cost-effectiveness-ratios (ICER) were calculated (horizon: 6 weeks, willingness-to-pay: $1,000/QALW or $50,000/ QALY). Results: DL-LUS was cost effective at the base case scenario (costs: $30,838 for DL vs. $30,791 for DL-LUS and effectiveness 3.81 QALWs DL vs. 3.82 QALW DL-LUS, resulting in a cost reduction of $9,220 per quality adjusted life week gained (or $479,469 per QALY). DL-LUS became less cost effective as the cost of ultrasound increased (threshold: $163.18) or the probability of exclusion from resection decreased (threshold 0.29) (Table represents the results of univariate analyses). Conclusions: Routine LUS with diagnostic laparoscopy for the assessment of resectability and exclusion of metastases is cost effective for patients with GBC. Until improvements in pre-operative imaging occur to decrease the probability of exclusion, this appears to be a feasible strategy. [Table: see text]

e19397 Background: Cemiplimab is a high-affinity, human, hinge-stabilized, monoclonal antibody that potently blocks the interactions of programmed cell death-1 (PD-1) with programmed cell death ligand-1 (PD-L1) and PD-L2. In September 2018, cemiplimab-rwlc became the first systemic therapy approved by the US Food and Drug Administration for the treatment of patients with advanced CSCC ineligible for curative surgery or radiotherapy. In a single-arm Phase II study (NCT02760498), cemiplimab demonstrated substantial antitumor activity, durable responses, and acceptable safety profile in patients with advanced CSCC. The aim of this analysis was to evaluate the cost-effectiveness of cemiplimab in patients with advanced CSCC from a US payer perspective. Methods: A partitioned survival model was developed to assess the cost-effectiveness of cemiplimab versus historical standard of care (SOC). All inputs were identified based on a systematic literature review (SLR), which was supplemented by expert opinion where necessary. The clinical inputs for cemiplimab were based on the individual patient data from the cemiplimab Phase II trial, whereas for SOC, the analysis was based on a pooled analysis of single-arm clinical trials and retrospective studies evaluating chemotherapy and epidermal growth factor receptor inhibitors (cetuximab, erlotinib, and gefitinib) identified via the SLR (6 of the 27 included studies). Overall survival and progression-free survival were extrapolated over a lifetime horizon using parametric functions consistent with guidance from the National Institute for Health and Care Excellence Decision Support Unit. Costs were included for drug acquisition, drug administration, management of adverse events, subsequent therapy, disease management, and terminal care. Unit costs were based on published 2019 US list prices. Results: In the base case, cemiplimab versus SOC resulted in an incremental cost-effectiveness ratio (ICER) of $99,024 per quality adjusted-life year (QALY), where incremental costs and QALYs were $372,425 and 3.76, respectively. At a willingness-to-pay threshold of USD $150,000 per QALY, the probabilistic sensitivity analysis suggests a 91% probability that cemiplimab is cost-effective when compared to SOC. Scenario analyses resulted in ICERs ranging from $90,326 to $147,944. Conclusions: Compared with historical SOC, cemiplimab is a cost-effective use of US payer resources for the treatment of advanced CSCC and is expected to provide value for money.

Background Policy makers in England advocate referral of patients with suspected dementia to Memory Assessment Services (MAS), but it is unclear how any improvement in patients’ health-related quality of life (HRQL) compares with the associated costs. Aims To evaluate the cost-effectiveness of MAS for the diagnosis and follow-up care of patients with suspected dementia. Method We analysed observational data from 1318 patients referred to 69 MAS, and their lay carers (n = 944), who completed resource use and HRQL questionnaires at baseline, three and six months. We reported mean differences in HRQL (disease-specific DEMQOL and generic EQ-5D-3L), quality-adjusted life years (QALYs) and costs between baseline and six months after referral to MAS. We also assessed the cost-effectiveness of MAS across different patient subgroups and clinic characteristics. Results Referral to MAS was associated with gains in DEMQOL (mean gain: 3.48, 95% confidence interval: 2.84 to 4.12), EQ-5D-3L (0.023, 0.008 to 0.038) and QALYs (0.006, 0.002 to 0.01). Mean total cost over six months, assuming a societal perspective, was £1899 (£1277 to £2539). This yielded a negative incremental net monetary benefit of −£1724 (−£2388 to −£1085), assuming NICE’s recommended willingness-to-pay threshold (£30,000 per QALY). These base case results were relatively robust to alternative assumptions about costs and HRQL. There was some evidence that patients aged 80 or older benefitted more from referral to MAS (p < 0.01 from adjusted mean differences in net benefits) compared to younger patients. MAS with over 75 new patients a month or cost per patient less than £2500 over six months were relatively more cost-effective (p < 0.01) than MAS with fewer new monthly patients or higher cost per patient. Conclusions Diagnosis, treatment and follow-up care provided by MAS to patients with suspected dementia appears to be effective, but not cost-effective, in the six months after diagnosis. Longer term evidence is required before drawing conclusions about the cost-effectiveness of MAS.

Background: The drug therapy of venous thromboembolism (VTE) presents a significant economic burden to the health-care system in low- and middle-income countries. To understand which anticoagulation therapy is most cost-effective for clinical decision-making , the cost-effectiveness of apixaban (API) versus rivaroxaban (RIV), dabigatran (DAB), and low molecular weight heparin (LMWH), followed by vitamin K antagonist (VKA), in the treatment of VTE in China was assessed.Methods: To access the quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICERs), a long-term cost-effectiveness analysis was constructed using a Markov model with 5 health states. The Markov model was developed using patient data collected from the Xijing Hospital from January 1, 2016 to January 1, 2021. The time horizon was set at 30 years, and a 6-month cycle length was used in the model. Costs and ICERs were reported in 2020 U.S. dollars. One-way sensitivity analysis and probabilistic sensitivity analysis (PSA) were used to test the uncertainties. A Chinese health-care system perspective was used.Results: In the base case, the data of 231 VTE patients were calculated in the base case analysis retrospectively. The RIV group resulted in a mean VTE attributable to 95% effective treatment. API, DAB, and VKA have a negative ICER (−187017.543, −284,674.922, and −9,283.339, respectively) and were absolutely dominated. The Markov model results confirmed this observation. The ICER of the API and RIV was negative (−216176.977), which belongs to the absolute inferiority scheme, and the ICER value of the DAB and VKA versus RIV was positive (110,577.872 and 836,846.343). Since the ICER of DAB and VKA exceeds the threshold, RIV therapy was likely to be the best choice for the treatment of VTE within the acceptable threshold range. The results of the sensitivity analysis revealed that the model output varied mostly with the cost in the DAB on-treatment therapy. In a probabilistic sensitivity analysis of 1,000 patients for 30 years, RIV has 100% probability of being cost-effective compared with other regimens when the WTP is $10973 per QALY. When WTP exceeded $148,000, DAB was more cost-effective than RIV.Conclusions: Compared with LMWH + VKA and API, the results proved that RIV may be the most cost-effective treatment for VTE patients in China. Our findings could be helpful for physicians in clinical decision-making to select the appropriate treatment option for VTE.

Case-mix adjusted mortality rates for patients undergoing hemodialysis for ESRD increased during the 1980s, despite the introduction of advanced dialysis technologies. Variations in dialysis practices suggest that excess mortality may be caused by inadequate uremic-toxin clearances. Cost-effectiveness analysis was used to assess whether attempts to improve uremic-toxin clearance are cost effective, assuming that these therapies are clinically effective. The medical literature was surveyed by the use of MEDLINE to assess the likelihood of clinical outcomes on the basis of the type of treatment given to the patient. Options considered in the model were delivered fractional urea clearance (Kt/V), dialysis-treatment duration, type of dialyzer membrane, dialysate, and ultrafiltration. Clinical outcomes included in the model were survival, severity of uremic symptoms, hospital days per year, and intradialytic hypotension and symptoms. Lifetime costs were calculated from data collected from a northern California dialysis center and abstracted from the literature. In the base-case scenario, it was assumed that increasing Kt/V to levels greater than 1 was effective in reducing morbidity and mortality. Under these assumptions, outpatient cost increased significantly, but the cost effectiveness of Kt/V equal to 1.5 was less than $50,000 per quality-adjusted life-year saved. These calculations indicate that, if higher levels of Kt/V prove clinically effective, they are also cost effective.

Abstract Background: Proton beam therapy (PBT) is a new-emerging cancer treatment in China. The treatment costs are high and not yet covered by Chinese public medical insurance. The advanced form of PBT, intensity-modulated proton radiation therapy (IMPT), has been confirmed to reduce normal tissue complication probability (NTCP) compared with conventional intensity-modulated photon-radiation therapy (IMRT) in patients with oropharyngeal cancer (OPC). This study evaluated the cost-effectiveness of IMPT versus IMRT for OPC patients in China, aiming at guiding proper use of PBT. Methods: On the basis of published data, a 7-state Markov model was designed for cost-effectiveness analysis, and an evaluation of average level was performed on a base case of 56-year-old under the hypothesis that IMPT could make a 25% NTCP-reduction concerning to long-term symptomatic dysphagia and xerostomia. Model robustness was examined using probabilistic sensitivity analysis, cohort analysis and tornado diagram. One-way sensitivity analyses were performed to identify cost-effective scenarios. IMPT was considered as cost-effective if the incremental cost-effectiveness ratio (ICER) was below the societal willingness-to-pay (WTP) threshold (3 times the gross domestic product per capita / quality-adjusted life year (QALY)).Results: Compared with IMRT, IMPT could provide an extra 0.724 QALYs at an additional cost of 34,926.6 US dollars ($), and made an ICER of $48,229.8/ QALY for the base case. At current WTP level of China ($30,828/QALY), cost-effective scenarios of IMPT existed in the following independent conditions: ≥ 57.3% NTCP-reduction (IMPT compared with IMRT) in dysphagia and xerostomia; patient age ≤ 38-year-old; or the cost of IMPT ≤ $37,398.1. The estimated cost-effective population that benefit from using PBT to treat OPC increased remarkably in the past 10 years with the economic growth, and reached to 559.7 million (about 40.0% of the China’s total population) in the year 2020. Conclusions: Currently, using PBT to treat OPC could be cost-effective in considerable proportion of China’s population. Considering the economic growth, the gradual increment of medical insurance coverage, as well as the proton treatment cost reduction along with more proton facility opening in the near future, it is estimated that PBT would benefit more Chinese OPC patients with respect to cost-effectiveness.

Objectives: Treatment options for articular cartilage lesions of the patella have evolved over the past several years due to the development of novel cell-based cartilage restoration techniques, including particulated juvenile allograft cartilage (PJAC) and matrix-induced autologous chondrocyte implantation (MACI). The objective of this study was to evaluate the cost -effectiveness of these modalities in the management of patellar cartilage defects. Methods: A Markov state-transition model was utilized to evaluate the cost-effectiveness of three strategies for patients with patellar chondral lesions: (1) nonoperative management, (2) PJAC, and (3) MACI. Probabilities, health utilities, and costs of surgical procedures and rehabilitation protocols were derived from institutional data and literature review. Effectiveness was assessed using quality-adjusted life-year (QALY). Cost-effectiveness was evaluated from societal and payer perspectives over a 15-year time horizon. The principal outcome measure was the incremental cost-effectiveness ratio (ICER). Sensitivity analyses were performed on pertinent model parameters to assess their effect on base case conclusions. Results: From a societal perspective, nonoperative management, PJAC, and MACI cost $4,140, $52,683, and $83,073 respectively. Nonoperative management, PJAC, and MACI were associated with 4.91, 7.07, and 7.79 QALYs gained, respectively. Therefore, PJAC and MACI were cost-effective relative to nonoperative management (ICERs $22,527/QALY and $27,456/QALY, respectively; Figure 1). Although MACI was more cost-effective than PJAC in the base case, this was strongly sensitive to the estimated probabilities of full versus intermediate benefit following PJAC and MACI (Table 1). If the probabilities of full and intermediate benefit following PJAC were assumed to be the same as those following MACI (i.e., PJAC and MACI were equally effective), then PJAC dominated MACI by being cheaper and more effective. At a $100,000/QALY willingness-to-pay threshold, MACI, PJAC, and nonoperative management were the preferred strategies in 63%, 33%, and 4% of the Monte Carlo probabilistic sensitivity analyses, respectively (Figures 2 and 3). Similar results were seen from a payer perspective. Conclusions: In the management of symptomatic patellar cartilage defects, PJAC and MACI were both cost-effective compared to nonoperative treatment in the management of symptomatic patellar cartilage defects; however, MACI was the preferred strategy in our base-case analysis. The cost-effectiveness of PJAC compared to MACI depended heavily on the probability of achieving full versus intermediate benefit after PJAC and MACI.
