BackgroundThe cost-effectiveness of endovascular thrombectomy (EVT) in patients with acute ischemic stroke due to M2 branch occlusion remains uncertain.ObjectiveTo evaluate the cost-effectiveness of EVT compared with medical management in patients with acute stroke presenting with M2 occlusion using a decision-analytic model.MethodsA decision-analytic study was performed with Markov modeling to estimate the lifetime quality-adjusted life years and associated costs of EVT-treated patients compared with no-EVT/medical management. The study was performed over a lifetime horizon with a societal perspective in the Unites States setting. Base case, one-way, two-way, and probabilistic sensitivity analyses were performed.ResultsEVT was the long-term cost-effective strategy in 93.37% of the iterations in the probabilistic sensitivity analysis, and resulted in difference in health benefit of 1.66 QALYs in the 65-year-old age groups, equivalent to 606 days in perfect health. Varying the outcomes after both strategies shows that EVT was more cost-effective when the probability of good outcome after EVT was only 4–6% higher relative to medical management in clinically likely scenarios. EVT remained cost-effective even when its cost exceeded US$200 000 (threshold was US$209 111). EVT was even more cost-effective for 55-year-olds than for 65-year-old patients.ConclusionOur study suggests that EVT is cost-effective for treatment of acute M2 branch occlusions. Faster and improved reperfusion techniques would increase the relative cost-effectiveness of EVT even further in these patients.

OBJECTIVE The utility of endovascular thrombectomy (EVT) in patients with acute ischemic stroke, large vessel occlusion (LVO), and low Alberta Stroke Program Early CT Scores (ASPECTS) remains uncertain. The objective of this study was to determine the health outcomes and cost-effectiveness of EVT versus medical management in patients with ASPECTS < 6. METHODS A decision-analytical study was performed with Markov modeling to estimate the lifetime quality-adjusted life-years (QALYs) and associated costs of EVT-treated patients compared to medical management. The study was performed over a lifetime horizon with a societal perspective in the US setting. RESULTS The incremental cost-effectiveness ratios were $412,411/QALY and $1,022,985/QALY for 55- and 65-year-old groups in the short-term model. EVT was the long-term cost-effective strategy in 96.16% of the iterations and resulted in differences in health benefit of 2.21 QALYs and 0.79 QALYs in the 55- and 65-year-old age groups, respectively, equivalent to 807 days and 288 days in perfect health. EVT remained the more cost-effective strategy when the probability of good outcome with EVT was above 16.8% or as long as the good outcome associated with the procedure was at least 1.6% higher in absolute value than that of medical management. EVT remained cost-effective even when its cost exceeded $100,000 (threshold was $108,036). Although the cost-effectiveness decreased with age, EVT was cost-effective for 75-year-old patients as well. CONCLUSIONS This study suggests that EVT is the more cost-effective approach compared to medical management in patients with ASPECTS < 6 in the long term (lifetime horizon), considering the poor outcomes and significant disability associated with nonreperfusion.

OBJECTIVEAs the cost of health care continues to increase, there is a growing emphasis on evaluating the relative economic value of treatment options to guide resource allocation. The objective of this systematic review was to evaluate the current evidence regarding the cost-effectiveness of cranial neurosurgery procedures.METHODSThe authors performed a systematic review of the literature using PubMed, EMBASE, and the Cochrane Library, focusing on themes of economic evaluation and cranial neurosurgery following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Included studies were publications of cost-effectiveness analysis or cost-utility analysis between 1995 and 2017 in which health utility outcomes in life years (LYs), quality-adjusted life years (QALYs), or disability-adjusted life years (DALYs) were used. Three independent reviewers conducted the study appraisal, data abstraction, and quality assessment, with differences resolved by consensus discussion.RESULTSIn total, 3485 citations were reviewed, with 53 studies meeting the inclusion criteria. Of those, 34 studies were published in the last 5 years. The most common subspecialty focus was cerebrovascular (32%), followed by neurooncology (26%) and functional neurosurgery (24%). Twenty-eight (53%) studies, using a willingness to pay threshold of US$50,000 per QALY or LY, found a specific surgical treatment to be cost-effective. In addition, there were 11 (21%) studies that found a specific surgical option to be economically dominant (both cost saving and having superior outcome), including endovascular thrombectomy for acute ischemic stroke, epilepsy surgery for drug-refractory epilepsy, and endoscopic pituitary tumor resection.CONCLUSIONSThere is an increasing number of cost-effectiveness studies in cranial neurosurgery, especially within the last 5 years. Although there are numerous procedures, such as endovascular thrombectomy for acute ischemic stroke, that have been conclusively proven to be cost-effective, there remain promising interventions in current practice that have yet to meet cost-effectiveness thresholds.

340 Background: Several new therapies have changed the landscape of prostate cancer (PCa) treatment, primarily due to their effectiveness in treating patients with mCRPC. Enza has garnered much attention, but is relatively expensive (~$3175/month). Met is less expensive (~$8.00/month) and has been used for decades to treat patients with non-insulin dependent diabetes. Two recent large population-based studies of PCa have demonstrated that diabetics taking Met had improved PCa specific and overall survival compared to those not taking Met. As a result, we hypothesized that Met has the potential to be a cost-effective adjunct therapy to Enza, although it is not currently used as such. Methods: We constructed a Markov-based decision analytic model to compare the cost-effectiveness of Enza alone versus Enza combined with Met. Through expert elicitation, we assumed that adding Met to Enza increases its efficacy by 15%. All other costs, utilities, and transition probabilities were derived from existing literature or expert elicitation. Effectiveness was measured using quality-adjusted life years (QALYs). Costs and QALYs were considered over a lifetime horizon and discounted at 5% per annum. Cost-effectiveness was considered using a willingness to pay threshold of $50 000/QALY. Results: Adding Met to Enza increases expected lifetime costs per patient by $83 651, and improves the expected effectiveness of treatment by 3.74 QALYs, compared to Enza alone. The incremental cost-effectiveness ratio is $22 374/QALY. Accounting for parameter uncertainty, adding Met to Enza has a 72% probability of being cost-effective. Conclusions: Although Met is not currently used as an adjunct therapy to Enza, doing so would likely be cost-effective provided it is as effective as we have assumed in our model. Additionally, our results indicate that the combination of Enza and Met could be among the most cost effective interventions in oncology. However, given the uncertainty around the effectiveness of such an adjunct therapy, our results support the need for further clinical trials to provide more robust evidence of the effectiveness of such a combination therapy in clinical practice.

Abstract Background: In this study, we analyze the cost-effectiveness of fruquintinib as third-line treatment for patients with metastatic colorectal cancer in China, especially after a recent price drop suggested by the National Healthcare Security Administration. Methods: A Markov model was developed to investigate the cost-effectiveness of fruquintinib compared to placebo among patients with metastatic colorectal cancer. Effectiveness was measured in quality-adjusted life years (QALY). The Chinese healthcare payer’s perspective was considered with a lifetime horizon, including direct medical cost (2019 US dollars [USD]). A willing‐to‐pay threshold was set at USD 27,130/QALY, which is three times the gross domestic product (GDP) per capita. We examined the robustness of the model in one-way and probabilistic sensitivity analysis.Results: Fruquintinib was associated with better health outcomes than placebo (0.640 vs 0.478 QALYs) with a higher cost (USD 20750.9 vs USD 12042.2), resulting in an incremental cost-effectiveness ratio (ICER) of USD 53508.7 per QALY. This ICER is 25% lower than the one calculated before the price drop (USD 70952.6 per QALY).Conclusion: After the price negotiation, the drug becomes cheaper and the ICER is lower, but the drug is still not cost effective under the standard of 3 times GDP willing‐to‐pay threshold. For patients with metastatic colorectal cancer in China, fruquintinib is not a cost-effective option under the current circumstances in China.

To evaluate the relative cost-effectiveness of nicotine replacement therapy (NRT) and bupropion SR for smoking cessation, the authors reviewed published studies and developed a decision analytic model from the UK National Health Services perspective. Irrespective of the methods or assumptions involved, the results of published studies consistently indicated that NRT for smoking cessation is cost-effective. No published studies have evaluated the relative cost-effectiveness of bupropion SR for smoking cessation. The results of the decision analyses indicated that, as compared with advice or counseling alone, the incremental cost per life-years saved is about $1,441~$3,455 for NRT, $920~$2,150 for bupropion SR, and $1,282~$2,836 for NRT plus bupropion SR. The cost-effectiveness of adding NRT and bupropion SR to advice or counseling for smoking cessation is better than many other accepted health care interventions.

Abstract Background Persons with HIV and tuberculosis (TB) co-infection require transaminase monitoring while on hepatotoxic medications. A novel paper-based, point-of-care transaminase test is in development at an anticipated cost of $1 per test. Methods To project long-term clinical outcomes and estimate the cost-effectiveness of using a paper-based fingerstick test to monitor for drug-induced liver injury (DILI), as compared with automated testing and with no laboratory monitoring. The design was a decision analytic model, including deterministic and probabilistic sensitivity analyses. Data sources were observational cohorts and a validation study of the paper-based test. The target population was HIV/TB co-infected persons in South Africa on antiretroviral therapy who were initiating TB therapy. Interventions: (1) clinical (no laboratory) monitoring; (2) monitoring using the paper-based test with a ≥120 IU/mL threshold for positivity; (3) monitoring using the paper-based test with a ≥200 IU/mL threshold for positivity; (4) monitoring using the paper-based test using 1 of 3 categories: &lt;120 IU/mL, 120 to 200 IU/mL, and &gt;200 IU/mL (“bin placement”); (5) monitoring using automated ALT testing using the same 3 categories (“automated testing”). The outcome measures were discounted quality-adjusted life-years (QALYs), costs, and incremental cost-effectiveness ratios (ICERs). Results The ICER of automated testing was $5180/QALY. Use of the paper-based test with the bin placement strategy was cost-effective compared with clinical monitoring alone. Conclusion At its current performance, monthly DILI monitoring by bin placement using the paper-based test was cost-effective, compared with clinical monitoring, in HIV/TB co-infected persons in South Africa.

Objectives: To evaluate the cost-effectiveness analysis (CEA) of caplacizumab in combination with plasmapheresis (PEX) and immunosuppression compared to PEX and immunosuppression in the treatment of acute episodes of iTTP. Methods: A Markov model was used to conduct the CEA from the perspective of the hospital, over a lifetime horizon. Clinical data derived from HERCULES trial and a systematic literature review. Economic input included direct costs only. Utility and disutility values were obtained from literature. Data on healthcare resources and costs were retrieved from HERCULES trial, literature, TTP guidelines and Italian tariffs. A sensitivity analysis was conducted. The cost-effectiveness probability was tested for several options of discount levels considering a suggested willingness to pay (WTP) threshold of € 60,000 in Italy. Results: The use of caplacizumab in combination with PEX and immunosuppression is associated with a positive difference in survival of 3.27 life years (24.53 vs 21.26) and in quality of life of 3.06 QALY (22.01 vs 18.96) when compared to PEX and immunosuppression. Caplacizumab leads to an ICER per life years of € 41,653 and an ICER per QALY of € 44,572. For the suggested WTP threshold, the probability of caplacizumab being cost-effective is 82.4% (no discount), 92.8% (15% discount), 95.3% (20% discount), 96.9% (25% discount) and 98.2% (30% discount). Conclusions: Caplacizumab in addition to PEX and immunosuppression is cost-effective, allowing the hospital to achieve greater efficiency in managing the burden of a life-threatening disease such as iTTP.

Abstract Purpose: To assess the cost-effectiveness of evolocumab, a PCSK9 (proprotein convertase subtilisin/kexin type 9) inhibitor, added to background statins therapy in patients with a recent acute coronary syndrome (ACS) event (in the past 12 months) and low-density lipoprotein cholesterol (LDL-C) levels ≥100 mg/dL in China.Methods: A health economic evaluation was performed from a Chinese healthcare perspective, using a Markov model over a lifetime horizon based on baseline CV event rate from claims database data and efficacy from the FOURIER trial. The health benefit was reflected in the decrease of LDL-C level, which led to the decrease of cardiovascular events. The cost of cardiovascular events and the utility value of each health state were derived from published literature. Sensitivity analysis were conducted to evaluate the effects of uncertainty in parameters and the robustness of the model. The cost-effectiveness of evolocumab was also explored in patients with recent MI, very high-risk (VHR) ASCVD and homozygous familiar hypercholesterolemia (HoFH).Results: In recent ACS patients, evolocumab was associated with incremental quality adjusted life years (QALYs) of 1.41 and incremental costs of 120,966 yuan vs. ezetimibe, both with background statins therapy, resulting in an ICER of 85,964 yuan per QALY gained. The probability that evolocumab is cost-effective at a threshold of 217,341 yuan (3 times per capita GDP, 2020) was 100% in patients with recent ACS, recent MI, VHR ASCVD and HoFH.Conclusion: Compared with ezetimibe, evolocumab was considered to be cost-effective in patients with a recent ACS event in China.

BackgroundTo evaluate the cost-effectiveness of endovascular thrombectomy (EVT) to treat large vessel occlusion (LVO) in patients with acute, minor stroke (National Institute of Health Stroke Scale (NIHSS) <6) and impact of occlusion site.MethodsA Markov decision-analytic model was constructed accounting for both costs and outcomes from a societal perspective. Two different management strategies were evaluated: EVT and medical management. Base case analysis was done for three different sites of occlusion: proximal M1, distal M1 and M2 occlusions. One-way, two-way and probabilistic sensitivity analyses were performed.ResultsBase-case calculation showed EVT to be the dominant strategy in 65-year-old patients with proximal M1 occlusion and NIHSS <6, with lower cost (US$37 229 per patient) and higher effectiveness (1.47 quality-adjusted life years (QALYs)), equivalent to 537 days in perfect health or 603 days in modified Rankin score (mRS) 0–2 health state. EVT is the cost-effective strategy in 92.7% of iterations for patients with proximal M1 occlusion using a willingness-to-pay threshold of US$100 000/QALY. EVT was cost-effective if it had better outcomes in 2%–3% more patients than intravenous thrombolysis (IVT) in absolute numbers (base case difference −16%). EVT was cost-effective when the proportion of M2 occlusions was less than 37.1%.ConclusionsEVT is cost-effective in patients with minor stroke and LVO in the long term (lifetime horizon), considering the poor outcomes and significant disability associated with non-reperfusion. Our study emphasizes the need for caution in interpreting previous observational studies which concluded similar results in EVT versus medical management in patients with minor stroke due to a high proportion of patients with M2 occlusions in the two strategies.
