ObjectiveThis study aimed to compare the health economic value of a non-invasive prenatal testing (NIPT) strategy against a second-trimester triple screening (STS) strategy for the detection of Down syndrome based on real-world data from China.DesignA decision-analytical model was developed to compare the cost-effectiveness of five strategies from a societal perspective. Cost and probability input data were obtained from the real-world surveys and published sources.SettingChina.ParticipantsWomen with a singleton pregnancy.InterventionsThe five strategies for screening were: (A) maternal age with STS (no NIPT); (B) STS plus NIPT screening; (C) age-STS plus NIPT screening (the currently referral strategy in China); (D) maternal age with NIPT screening and (E) universal NIPT screening.Main outcome measuresIncremental cost-effectiveness ratios (ICERs) per additional Down syndrome case terminated, univariate and probabilistic sensitivity analysis and cost-effectiveness acceptability curves were obtained.ResultsStrategy A detected the least number of Down syndrome cases. Compared with the cheapest Strategy B, Strategy D had the lowest ICER (incremental cost, US$98 944.85 per additional Down syndrome case detected). Strategy D had the highest probability of being cost-effective at the willingness-to-pay level between US$110 000.00 and US$535 000.00 per additional Down syndrome case averted. Strategy E would not be cost-effective unless the unit cost of the NIPT could be decreased to US$60.50.ConclusionIntroducing NIPT screening strategies was beneficial over the use of STS strategy alone. Evaluating maternal age in combination with the NIPT screening strategy performs better than China’s currently referral strategy in terms of cost-effectiveness and safety. Lowering the price of NIPT and optimising payment methods are effective measures to promote universal NIPT strategies in China.

INTRODUCTION:The analysis of cell-free fetal DNA in maternal blood, also called Non-Invasive Prenatal Testing (NIPT), represents an emerging technology and a possible alternative/complement to current prenatal screening based on biochemical and sonographic markers for Down Syndrome (DS) detection.The aim of the study was to compare the application of NIPT with the prenatal diagnosis/screening procedures currently applied in the Basque Country.METHODS:An analytical decision model was developed to assess the costs and consequences, comparing current prenatal screening, NIPT as a contingency test in high-risk cases and NIPT as a first-line screening test. An economic analysis was conducted to determine which strategy was more cost-effective. Sensitivity analyses were performed (1).RESULTS:For a population of 97,074 pregnant women in gestational week 14 and a cut-off point of 1:270, NIPT as a contingent test was not cost-effective, detecting two cases less of DS and causing a lower number of miscarriages related to invasive-testing (4 versus 23) at a slightly lower cost (EUR8,111,351 versus EUR8,901,872).For risk cut-off points of 1:500 or 1:1000 for contingent NIPT, the number of DS cases detected increased, as did the cost. It could be cost-effective compared with current prenatal screening, (EUR61,763 or EUR256,123 per extra DS case detected, respectively).Using the NIPT as a primary test detected more DS cases (296 versus 271) and caused less miscarriages (5 versus 23), at a substantially higher cost (EUR41,395,645 versus EUR8,901,872). Cost-effectiveness analysis indicated that it was more expensive and more effective.Univariant sensitivity-analysis showed that when the price of the NIPT as primary test was EUR76, it was dominant compared with current prenatal screening. It was also cost-effective compared with the NIPT as a contingent test (EUR9,869 per extra DS case detected).CONCLUSIONS:The study shows that NIPT had higher detection rates for DS in different scenarios, but the cost constitutes a limiting factor for implementation in the Basque Health System.

BackgroundAddition of gemcitabine and cisplatin (GP) or docetaxel and cisplatin plus fluorouracil (TPF) to concurrent chemoradiotherapy (CCRT) significantly improved survival in locoregionally advanced nasopharyngeal carcinoma (NPC). However, an economic evaluation of these regimens remains unknown. The purpose of this study is to compare the cost-effectiveness of GP versus TPF regimen in the treatment of locoregionally advanced NPC in China.Materials and methodsA comprehensive Markov model was developed to evaluate the health and economic outcomes of GP versus TPF regimen for patients with locoregionally advanced NPC. Baseline and clinical outcome were derived from 158 patients with newly diagnosed stage III-IVA NPC between 2010 and 2015. We evaluated the quality-adjusted life-years (QALYs), costs, and incremental cost-effectiveness ratios (ICERs) from the perspective of the Chinese healthcare system. One-way sensitive analysis explored the impact of uncertainty in key model parameters on results, and probabilistic uncertainty was assessed through a Monte Carlo probabilistic sensitivity analysis.ResultsGP regimen provided an additional 0.42 QALYs with incremental cost of $3,821.99, resulting in an ICER of $9,099.98 per QALY versus TPF regimen at the real-world setting. One-way sensitivity analysis found that the results were most sensitive to the cost and proportion of receiving subsequent treatment in two groups. The probability that GP regimen being cost-effective compared with TPF regimen was 86.9% at a willingness-to-pay (WTP) of $31,008.16 per QALY.ConclusionUsing real-world data, GP regimen was demonstrated a cost-effective alternative to TFP regimen for patients with locoregionally advanced NPC in China. It provides valuable evidence for clinicians when making treatment decisions to improve the cost-effectiveness of treatment.

AbstractObjectivesThere is little evidence in China regarding the cost-effectiveness of non-invasive prenatal testing (NIPT) for Down syndrome (DS). This study aims to evaluate the cost-effectiveness of NIPT and provide evidence to inform decision-making.MethodsTo determine the cost-effectiveness of NIPT for DS, a decision-analytic model was developed using the TreeAge Pro software from a societal perspective in a simulated cohort of 10 000 pregnant women. Main indicators were based on field surveys from sampled hospitals in four locations in China and a literature review.ResultsThe conventional maternal serum screening (CMSS) strategy, contingent screening strategy (NIPT delivered to high risk pregnant women after CMSS), and universal screening strategy could prevent 3.02, 7.53, and 9.97 DS births, respectively. NIPT would decrease unnecessary invasive procedures, resulting in fewer procedure-related miscarriages. The cost-effectiveness ratio of the contingent screening strategy was the lowest. When compared with the CMSS strategy, the incremental cost per DS birth averted by the contingent screening strategy and universal screening strategy were USD 20,160 and 352,388, respectively. One-way sensitivity analysis showed that, if the cost of NIPT could be decreased to USD 76.92, the cost-effectiveness ratio of the universal screening strategy would be lower than the CMSS strategy.ConclusionsAlthough NIPT has the merits of greater effectiveness and safety, CMSS is unlikely to be replaced by NIPT at this time because of NIPT's higher cost. Contingent screening may be an appropriate strategy to balance the effectiveness and cost factors of the new genetic testing technology.

Abstract In the trends of increasing advanced maternal age (AMA) and decreasing cost of Noninvasive Prenatal Testing (NIPT), we investigated the benefits and cost effectiveness of NIPT as primary or contingent strategies for trisomy 21 (T21). A theoretical model involving 1,000,000 single pregnancies was established. We presented five screening scenarios, primary NIPT (Strategy 1), contingent NIPT after traditional triple serum screening higher than 1/300 or 1/1000 (Strategy 2-1 or Strategy 2-2) and age-based (Strategy 3). Strategy 3 was stratified, in which 1) for advanced maternal age (AMA) of 40 and more, prenatal diagnosis was offered, 2) for AMA of 35 to 39, NIPT was introduced, 3) if younger than 35, contingent strategy with screening risk higher than 1:300 (Strategy 3-1) or 1:1000 (Strategy 3-2) will be offered NIPT. Parameters were referred to publications or on-site verification. The primary outcome was incremental cost analysis for each strategy on baseline and alterative assumptions, which take aging society, reducing cost of NIPT and compliance into consideration. The second outcomes were total cost, cost-effect and cost-benefit analysis. If the incremental cost was less than 0.215 million US$, which was cost for raising one T21 child, or the benefit-to-cost ratio over 1, then the strategy was defined as “cost-effective”. The anticipated prenatal diagnosis was significantly reduced in Strategy 1 and 2, most notably in Strategy 2-1. For the incremental costs, strategy 2-1 was set as baseline. All other strategy costed more than raising one T21 except 3-1. In sensitivity analysis, strategy 1 costed the least when NIPT was lower than 47 US$. If NIPT less than 131 US$, the incremental cost of any strategy was less than 0.215 million US$. When the proportion of AMA accounted for more than 15% and 20% of population, incremental costs of strategy 3-1 and 3-2 were cost effective. In conclusion, contingent NIPT after traditional triple serum screening (risk higher than 1/300) was optimal in total cost (130 million US$), cost-effect (33.4 thousand US$) and cost-benefit (ratio=4.90) analysis of the model. Age-based strategy was optimal as AMA proportion and NIPT acceptance increased. The primary NIPT was most effective for certain price.

Cost Effective Treatment

Background:Several randomized controlled trials of cholinesterase inhibitors and memantine in mild to moderate vascular dementia have demonstrated the efficacy of these treatments. However, given these drugs incur considerable cost, the economic argument for their use is less clear.Objective:To determine the incremental cost-effectiveness of cholinesterase inhibitors and memantine for mild to moderate vascular dementia.Design:A decision analysis model using a 24-28 week time horizon was developed. Outcomes of cholinesterase inhibitors and memantine and probabilities of adverse events were extracted from a systematic review. Costs of adverse events, medications, and physician visits were obtained from local estimates. Robustness was tested with probabilistic sensitivity analysis using a Monte Carlo simulation.Interventions:Donepezil 5 mg daily, donepezil 10 mg daily, galantamine 16-24 mg daily, rivastigmine flexible dosing up to 6 mg twice daily, or memantine 10 mg twice daily versus standard care.Main Outcome Measures:Incremental cost-effectiveness ratio (ICER) expressed as cost per unit decrease in the Alzheimer's Disease Assessment Scale-cognitive (ADAS-cog) subscale.Results:Donepezil 10 mg daily was found to be the most cost-effective treatment with an ICER of $400.64 (95%CI, $281.10-$596.35) per unit decline in the ADAS-cog subscale. All other treatments were dominated by donepezil 10 mg, that is, more costly and less effective.Conclusion:From a societal perspective, treatment with cholinesterase inhibitors or memantine was more effective but also more costly than standard care for mild to moderate vascular dementia. The donepezil 10 mg strategy was the most cost-effective and also dominated the other alternatives.

Aims Total hip arthroplasty (THA) with dual-mobility components (DM-THA) has been shown to decrease the risk of dislocation in the setting of a displaced neck of femur fracture compared to conventional single-bearing THA (SB-THA). This study assesses if the clinical benefit of a reduced dislocation rate can justify the incremental cost increase of DM-THA compared to SB-THA. Methods Costs and benefits were established for patients aged 75 to 79 years over a five-year time period in the base case from the Canadian Health Payer’s perspective. One-way and probabilistic sensitivity analysis assessed the robustness of the base case model conclusions. Results DM-THA was found to be cost-effective, with an estimated incremental cost-effectiveness ratio (ICER) of CAD $46,556 (£27,074) per quality-adjusted life year (QALY). Sensitivity analysis revealed DM-THA was not cost-effective across all age groups in the first two years. DM-THA becomes cost-effective for those aged under 80 years at time periods from five to 15 years, but was not cost-effective for those aged 80 years and over at any timepoint. To be cost-effective at ten years in the base case, DM-THA must reduce the risk of dislocation compared to SB-THA by at least 62%. Probabilistic sensitivity analysis showed DM-THA was 58% likely to be cost-effective in the base case. Conclusion Treating patients with a displaced femoral neck fracture using DM-THA components may be cost-effective compared to SB-THA in patients aged under 80 years. However, future research will help determine if the modelled rates of adverse events hold true. Surgeons should continue to use clinical judgement and consider individual patients’ physiological age and risk factors for dislocation. Cite this article: Bone Joint J 2021;103-B(12):1783–1790.
