AbstractBackgroundThere is a developing outbreak of Neisseria meningitidis serotype W (MenW) in the Netherlands. In response, those aged 14 months and 14 years are vaccinated with the conjugated MenACWY vaccine. In the spring of 2018 we aimed to explore the impact of adding a one-off catch-up campaign targeting those aged 15-18 years on the transmission of MenW and the cost-effectiveness of such a campaign.MethodsWe estimated the growth rate of the MenW outbreak and quantified the impact of various targeted vaccination strategies on the reproductive number, and subsequently projected the future incidence with and without vaccination. Future cases were expressed in costs and QALYS and the incremental cost-effectiveness ratio was obtained.ResultsWe estimate a reproductive number of around 1.4 (95%CI 1.2-1.7) over the period February 2016-February 2018. Adding the catch-up campaign reduces the reproductive number five years earlier than without a catch-up campaign, to a level around 1.2. The vaccination campaign, including the catch-up, will prevent around 100 cases per year in our base case scenario. Given the projected impact and realistic assumptions on costs and QALYs, adding the catch-up can be considered cost-effective using a threshold of €20,000 per QALY.ConclusionAdding the catch-up campaign targeting those aged 15-18 brings the impact of vaccination on reducing transmission five years forward and directly prevents a high-incidence age group from carriage and disease. Such a campaign can be considered cost-effective. Our study did underpin the decision to introduce a catch-up campaign in spring 2019. Furthermore, our applied method can be of interest for anyone solving vaccine allocation questions in a developing outbreak.

Objective: To determine the cost-effectiveness of 2 strategies for post-discharge suicide prevention, an Enhanced Contact intervention based on repeated in-person and telephone contacts, and an individual 2-month long problem-solving Psychotherapy program, in comparison to facilitated access to outpatient care following a suicide attempt. Methods: We conducted a cost-effectiveness analysis based on a decision tree between January and December 2019. Comparative effectiveness estimates were obtained from an observational study conducted between 2013 and 2017 in Madrid, Spain. Electronic health care records documented resource use (including extra-hospital emergency care, mortality, inpatient admission, and disability leave). Direct cost data were derived from Madrid’s official list of public health care prices. Indirect cost data were derived from Spain’s National Institute of Statistics. Results: Both augmentation strategies were more cost-effective than a single priority outpatient appointment considering reasonable thresholds of willingness to pay. Under the base-case scenario, Enhanced Contact and Psychotherapy incurred, respectively, €2,340 and 6,260 per averted attempt, compared to a single priority appointment. Deterministic and probabilistic sensitivity analyses showed both augmentation strategies to remain cost-effective under several scenarios. Enhanced Contact was slightly cost minimizing in comparison to Psychotherapy (base-case scenario: €−196 per averted attempt). Conclusions: Two post-discharge suicide prevention strategies based on Enhanced Contact and Psychotherapy were cost-effective in comparison to a single priority appointment. Increasing contacts between suicide attempters and mental health-care providers was slightly cost minimizing compared to psychotherapy.

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]

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 Electroconvulsive therapy (ECT) has long been used for treating individuals with treatment-resistant depression (TRD). Esketamine has recently emerged as a new treatment for TRD due to its rapid antidepressant effects. To further inform the decision regarding choice of treatment, this paper aims to evaluate whether ECT or esketamine is the more cost-effective option. Methods The cost-effectiveness was derived as cost per quality-adjusted life-year (QALY) using a Markov model from a societal and life-time perspective. The incremental cost-effectiveness ratio (ICER) was calculated. Health states included different depression and remission states and death. Data to populate the model was derived from randomised controlled trials and other research. Various sensitivity analyses were carried out to test the robustness of the model. Results The base case scenario shows that ECT is cost-effective compared to esketamine and yields more QALYs at a lower cost. The sensitivity analysis shows that ECT is cost-effective in all scenarios and ECT dominates esketamine in 12 scenarios. Conclusions This study found that, from a cost-effectiveness point of view, ECT should be the first-hand option for individuals with TRD, when other first line treatments have failed. Considering the lack of economic evaluation of ECT and esketamine, this study is of great value to decision makers.

While sealants are more effective than fluoride varnish in reducing the development of new carious lesions on occlusal surfaces, and a course of treatment requires fewer clinical visits, they are more expensive per application. This analysis assessed which treatment is more cost-effective. We estimate the costs of sealants and fluoride varnish over a 4-year period in a school-based setting, and compare this to existing estimates of the relative benefits in terms of caries reduction to calculate the relative cost-effectiveness of these two preventive treatments. In our base case scenario, varnish is more cost-effective in preventing caries. Allowing for caries benefits to nonocclusal surfaces further improves the cost-effectiveness of varnish. Although we found that varnish is more cost-effective, the results are context specific. Sealants become equally cost-effective if a dental hygienist applies the sealants instead of a dentist, while varnish becomes increasingly cost-effective when making comparisons outside of a traditional dental clinic setting.

Introduction:Paroxysmal atrial fibrillation (PAF) represents a significant economic burden to the healthcare system. Catheter ablation is a commonly adopted treatments for PAF, and cryoballoon ablation (CBA) has been recently proven to be as effective as radiofrequency ablation (RFA). This study aims to evaluate the cost-effectiveness of CBA versus RFA in patients with drug-refractory PAF in China.Methods:A Markov model was developed to study the effects and the costs of CBA versus RFA. Cost and probability inputs data were obtained mainly from a real-world study of 85 CBA and 284 RFA patients treated in a tertiary hospital between July 2014 and July 2016. Propensity score matching was used to overcome retrospective bias, resulting in including 75 patients in each group. Input data gaps were closed with literature review and advisory board. A simulation was carried out for 14 cycles/years, and a discount rate of 3 percent was used. Then, a probabilistic sensitivity analysis was carried out with Monte Carlo approach.Results:In the base case scenario, the cumulative costs incurred by the CBA and RFA groups were CNY 132,222 (USD 20,767) and CNY 147,304 (USD 23,136), respectively. Over the 14-year period, the quality-adjusted life years (QALYs) gained by the CBA group was 7.85 versus 7.71 in the RFA group. The incremental cost-effectiveness ratio for CBA versus RFA was thus CNY 107,729 (USD 16,920)/QALY. Model results were most sensitive to the cost incurred during the first hospitalization, recurrence rate, and relative utility weights. The probability of CBA being cost-effective for willingness to pay thresholds of per capita GDP in China was estimated to be 99 percent.Conclusions:Compared with RFA, CBA is a cost-saving treatment providing increased QALYs. It represents good value for money for patients with drug-refractory PAF in China. However, further evidence needs to be generated from larger-scale studies in China.

Objective: The transfusion of blood components and blood products in cardiac surgery patients can be guided by protocols based on standard laboratory tests and/or clinical decisions (Standardof-Care, SOC) or viscoelastic haemostatic assays (VHA). The aim of this study is to evaluate the cost-effectiveness and budget impact of VHAs compared to SOC. Methods: A decision tree model was built in TreeAge Pro® 2009. Costs and benefits were taken from the medical literature. The costeffectiveness was evaluated in a base-case scenario and a worst-case scenario, considering low costs of adverse events. The budget impact was evaluated from data taken from Datasus. Cost data were measured in 2019 USD and outcomes were measured in QALYs. Results: VHAs were considered dominant in the base-case scenario and very cost-effective in the worst-case scenario (ICER = $1,083.21 USD/QALY). The budget impact analysis varied from a cost-saving result in the base-case scenario to a reasonable increase in cost in the worst-case scenario. Since the total market share of the technology is unlikely, a reasonable estimative for the base-case scenario and the worst-case scenario are about -$275 million USD and $132 million USD, respectively. Conclusion: We conclude that the VHAs are cost-effective and should be recommended for the use in the perioperative period of cardiac surgeries, especially for patients with a high risk of hemorrhage or coagulation problems.

This study evaluated the cost-effectiveness of the consumption of a milk powder product fortified with potassium (+1050.28 mg/day) and phytosterols (+1200 mg/day) to lower systolic blood pressure and low-density lipoprotein cholesterol, respectively, and, therefore, the risk of myocardial infarction (MI) and stroke among the 35–75-year-old population in Malaysia. A Markov model was created against a do-nothing option, from a governmental perspective, and with a time horizon of 40 years. Different data sources, encompassing clinical studies, practice guidelines, grey literature, and statistical yearbooks, were used. Sensitivity analyses were performed to evaluate the impact of uncertainty on the base case estimates. With an incremental cost-effectiveness ratio equal to international dollars (int$) 22,518.03 per quality-adjusted life-years gained, the intervention can be classified as very cost-effective. If adopted nationwide, it would help prevent at least 13,400 MIs, 30,500 strokes, and more than 10,600 and 17,100 MI- and stroke-related deaths. The discounted cost savings generated for the health care system by those who consume the fortified milk powder would amount to int$8.1 per person, corresponding to 0.7% of the total yearly health expenditure per capita. Sensitivity analyses confirmed the robustness of the results. Together with other preventive interventions, the consumption of milk powder fortified with potassium and phytosterols represents a cost-effective strategy to attenuate the rapid increase in cardiovascular burden in Malaysia.

Abstract. The spatial distribution of groundwater fluxes through a streambed can be highly variable, most often resulting from a heterogeneous distribution of aquifer and streambed permeabilities along the flow pathways. Using a groundwater flow and heat transport model, we defined four scenarios of aquifer and streambed permeability distributions to simulate and assess the impact of subsurface heterogeneity on the distribution of groundwater fluxes through the streambed: (a) a homogeneous low-K streambed within a heterogeneous aquifer; (b) a heterogeneous streambed within a homogeneous aquifer; (c) a well connected heterogeneous low-K streambed within a heterogeneous aquifer; and (d) a poorly connected heterogeneous low-K streambed within a heterogeneous aquifer. The simulation results were compared with a base case scenario, in which the streambed had the same properties as the aquifer, and with observed data. The results indicated that the aquifer has a stronger influence on the distribution of groundwater fluxes through the streambed than the streambed itself. However, a homogeneous low-K streambed, a case often implemented in regional-scale groundwater flow models, resulted in a strong homogenization of fluxes, which may have important implications for the estimation of peak mass flows. The flux distributions simulated with heterogeneous low-K streambeds were similar to the flux distributions of the base case scenario, despite the lower permeability. The representation of heterogeneous distributions of aquifer and streambed properties in the model has been proven to be beneficial for the accuracy of flow simulations.

Abstract Background Most measles importations are due to returning US travelers infected during international travel. We projected clinical outcomes and assessed cost-effectiveness of pretravel evaluation for measles immunity and MMR vaccination among eligible adult US international travelers. Methods We designed a decision tree to investigate pretravel evaluation compared with no evaluation from the societal perspective. Data from the Global TravEpiNet Consortium and published literature informed input parameters (Figure 1). Outcomes included measles cases averted per 10 million travelers, costs, and the incremental cost-effectiveness ratio (ICER, Δcosts/Δmeasles cases averted); we considered ICERs < $100,000/measles case averted to be cost-effective. We performed sensitivity analyses to assess the impact of varying the probability of exposure based on travel destination, and the percentage of travelers with pre-existing measles immunity. Results In the base case, departure after pretravel evaluation resulted in 16 measles importations and 46 transmissions per 10 million travelers and cost $132 million, vs without pretravel evaluation (26 importations and 87 transmissions per 10 million travelers, costing $22 million). Pretravel evaluation averted 51 measles cases per 10 million travelers with an ICER of $2.2 million per case averted. Results were most sensitive to the probability of measles exposure and the traveler’s pre-existing immunity (Figure 2). Pretravel evaluation was cost-effective for travelers to Asia if pre-existing measles immunity was <80%. Evaluation was always cost-effective for travelers to Africa when pre-existing immunity was less than 100% and became cost saving when the percentage of immune travelers was lower (<70%). Travelers who were more likely to be non-immune and were visiting destinations with higher probabilities of exposure were most likely to benefit from pretravel evaluation for measles immunity at excellent economic value. Conclusion As risk of measles exposure increases and likelihood of travelers’ pre-existing immunity decreases, it can be cost-effective or cost saving to assess US international travelers’ measles immunity status and vaccinate with MMR prior to departure.
