Immunosuppressive therapy for progressive idiopathic membranous nephropathy: a cost-effectiveness analysis in China

BackgroundThis study aims to evaluate the cost-effectiveness of immunosuppressive therapy for patients with progressive idiopathic membranous nephropathy (IMN) from the Chinese healthcare system perspective.MethodsTo estimate the cost-effectiveness of four regimens namely cyclophosphamide, cyclosporine, rituximab and tacrolimus-rituximab in treatment of IMN recommended by the updated Kidney Disease: Improving Global Outcomes (KDIGO) guideline 2021, a Markov model with five discrete states (active disease, remission, dialysis, kidney transplant and death) based on IMN patients aged 50 or above over a 30-years time horizon was constructed. Total costs were imputed from the Chinese healthcare system perspective, and health outcomes were converted into quality-adjusted life years (QALYs). The incremental cost-effectiveness ratio (ICER) was used to describe the results. The willingness-to-pay (WTP) threshold was set at $12,044 (China’s 2021 Gross Domestic Product per capita). Sensitivity analyses were performed to test the uncertainties of the results.ResultCompared with cyclophosphamide, both cyclosporine (incremental cost $28,337.09, incremental QALY-1.63) and tacrolimus-rituximab (incremental cost $28,324.13, incremental QALY -0.46) were considered at strictly dominated for their negative values in QALYs, and the ICER value of rituximab was positive (incremental cost $9,162.19, incremental QALY 0.44). Since the ICER of rituximab exceeds the pre-determined threshold, cyclophosphamide was likely to be the best choice for the treatment of IMN within the acceptable threshold range. The results of the sensitivity analysis revealed that the model outcome was mostly affected by the probability of remission in rituximab. In a probabilistic sensitivity analysis, cyclophosphamide had 62.4% probability of being cost-effective compared with other regimens when the WTP was $12,044 per QALY. When WTP exceeded $18,300, rituximab was more cost-effective than cyclophosphamide.ConclusionCompared with cyclosporine, rituximab and tacrolimus-rituximab, our model results indicated that cyclophosphamide represented the most cost-effective regimen for patients with progressive IMN in China.

Comparing the cost-effectiveness of sintilimab + pemetrexed plus platinum and pemetrexed plus platinum alone as a first-line therapy for Chinese patients with nonsquamous non-small cell lung cancer.

Pemetrexed plus platinum alone is the conventional first-line therapy for locally advanced metastatic nonsquamous non-small cell lung cancer (NSCLC) without targetable genetic aberrations. The ORIENT-11 trial revealed that sintilimab + pemetrexed plus platinum could yield more survival benefits for patients with nonsquamous NSCLC. The present study aimed to assess the cost-effectiveness of sintilimab + pemetrexed plus platinum vs. that of pemetrexed plus platinum alone as the first-line therapy for patients with nonsquamous NSCLC to inform clinically rational drug use and provide a basis for medical decision-making. A partitioned survival model was created to evaluate the cost-effectiveness of two groups from the perspective of the healthcare system in China. The clinical data for adverse event probabilities and extrapolating long-term survival originally collected in a phase III clinical trial (ORIENT-11) were retrieved. Local public databases and literature were used to acquire data on utility and cost. The heemod package in R software was used to calculate the life years (LYs), quality-adjusted LYs (QALYs), and total costs in each group to generate the incremental cost-effectiveness ratio (ICER) in the base case and to conduct deterministic sensitivity analysis (DSA) and probabilistic sensitivity analysis (PSA). Our base case analysis (BCA) revealed that sintilimab combined with pemetrexed plus platinum provided an increase of 0.86 in QALYs with an increasing cost of United State dollar (USD) $4,317.84 relative to pemetrexed plus platinum in Chinese patients with nonsquamous NSCLC who were negative for targetable genetic variations, which induced an ICER of USD $5,020.74/QALY. The ICER value was lower than the set threshold value. The results exhibited strong robustness in the sensitivity analysis. In DSA, the parameter for the overall survival (OS) curve in chemotherapy and the cost of best supportive care were the main factors that impacted the result of the ICER. The PSA indicated that sintilimab and chemotherapy combination therapy was cost-effective. This study suggests that the combination of sintilimab + pemetrexed plus platinum is cost-effective as a first-line therapy in Chinese patients with nonsquamous NSCLC who are negative for targetable genetic variations from the perspective of the healthcare system.

Cost-effectiveness of Prophylactic Retropubic Sling at the Time of Vaginal Prolapse Surgery

ABSTRACT The increasing proportion of elderly Americans has brought about an anticipation of 50% rise in prolapse surgeries by 2050. It is anticipated that 25% to 40% of patients undergoing surgeries will develop de novo stress urinary incontinence (SUI) after prolapse repair. The Outcomes Following Vaginal Prolapse Repair with Midurethral Sling (OPUS) found a 36% reduction in the risk for de novo SUI, but also demonstrated increased risk of bladder perforations, urinary tract infections, and incomplete bladder emptying symptoms (N Engl J Med. 2012;366:2358–2367). As a result, pelvic reconstructive surgeons often vary their approach toward prophylactic MUS at the time of vaginal prolapse repair (VPR). Although a cost-effectiveness analysis found universal MUS placement to be the most cost-effective strategy over both selective and staged strategies (J Urol. 2013;190:1306–1312), this analysis did not include an arm for the less-costly option of using a selective approach via a prolapse-reduced cough stress test (CST). In addition, Richardson analysis of patients undergoing sacral colpopexy lacks generalizability for VPR surgeries (which account for two thirds of all prolapse surgeries). The manuscript described here therefore tested the cost-effectiveness of 3 generalizable MUS utilization strategies for preventing de novo SUI within 1 year post-VPR. Three approaches were compared: (1) staged strategy performing VPR with later MUS placement only for de novo SUI; (2) universal sling placement at the time of VPR; and (3) selective sling placement with MUS at the time of VPR when occult SUI was observed at the time of preoperative prolapse-reduced CST. A representative population of women with symptomatic pelvic organ prolapse (at least stage II) was modeled. Included in the VPR model was colpocleisis, apical suspension, or anterior colporrhaphy, with or without hysterectomy. The base assumption was that all VPRs were uncomplicated and anatomically successful. Subsequent treatment pathways were formed based on the 3 aforementioned options if de novo SUI was to occur. A 2017 systematic review by van der Ploeg was used for obtaining literature to gain point estimates concerning the risk for postoperative SUI (Int Urogynecol J. 2016;27:1029–1038). The search was performed via PubMed through January 2017, and exclusionary criteria were as follows: studies examining urodynamics preoperatively, abdominal prolapse repairs, duplicate studies, and studies lacking clear definitions for VPR, MUS, or SUI. Using data from 3 previous studies, for a selective MUS, the authors estimated the rate of de novo SUI after VPR with a negative preoperative CST to be 33.6%. The authors determined the existence of 4 possible adverse outcomes following MUS: (1) persistent SUI, (2) sling lysis required for voiding dysfunction, (3) mesh exposure requiring excision, and (4) anticholinergic medications required for de novo overactive bladder. Information on costs was gathered Physician Fee Schedules from the 2020 Centers for Medicare and Medicaid Services. Incremental cost-effectiveness ratio was the primary outcome modeled, defined as the ratio of the cost difference compared with the difference in quality-adjusted life years between scenarios. Results indicated that costs were as follows for various approaches: $1051.70 per patient for staged strategy, $1093.75 for selective MUS, and $1125.54 for universal MUS. The incremental cost-effectiveness ratio value for selective MUS calculated at $2664/quality-adjusted life years, rendering it the most cost-effective and preferred strategy. The variable with the greatest effect on model cost was the proportion of patients experiencing postoperative SUI electing to undergo repeat surgical intervention via MUS placement. Strengths of the study include its use of high-quality Centers for Medicare and Medicaid Services data for costs and point estimates. Because these data hails from the large portion of older Americans covered by Medicare (the most at risk for prolapse surgery), it avoids the inclusion of large variabilities innate to individual hospital systems. In addition, a 1-way sensitivity analysis was performed based on all case assumptions, thereby demonstrating the robustness of the study model. Limitations of the study included the expected hindrance of estimations and assumptions about event incidences. A 1-year time horizon was analyzed, although this may be reasonable because risks of complications dwindle over time. Furthermore, the study only considered women with de novo SUI to have the options of no treatment or MUS placement, disregarding costs of alternative procedures such as pelvic floor physical therapy, pessary, repeat MUS, urethral bulking, or other surgical interventions. Finally, all possible common outcomes after VPR were not included, such as urinary tract infections, pain, or postoperative urinary retention requiring short-term catheterization. In this study, the overall preference for treating de novo SUI via vaginal prolapse surgeries was the selective prophylactic midurethral sling. Patient counseling should occur to inform about the risks and benefits related to prophylactic sling surgeries (including the possibility of de novo SUI after VPR). Decisions regarding treatment strategy ought to be made using each patient’s priorities and treatment goals in discussion with her surgeon.

Cost-effectiveness of Intensive vs Standard Blood Pressure Control Among Older Patients With Hypertension

Older patients with hypertension receiving intensive systolic blood pressure control (110-130 mm Hg) have lower incidences of cardiovascular events than those receiving standard control (130-150 mm Hg). Nevertheless, the mortality reduction is insignificant, and intensive blood pressure management results in more medical costs from treatments and subsequent adverse events. To examine the incremental lifetime outcomes, costs, and cost-effectiveness of intensive vs standard blood pressure control in older patients with hypertension from the health care payer's perspective. This economic analysis was conducted with a Markov model to examine the cost-effectiveness of intensive blood pressure management among patients aged 60 to 80 years with hypertension. Treatment outcome data from the Trial of Intensive Blood-Pressure Control in Older Patients With Hypertension (STEP trial) and different cardiovascular risk assessment models for a hypothetical cohort of STEP-eligible patients were used. Costs and utilities were obtained from published sources. The incremental cost-effectiveness ratio (ICER) against the willingness-to-pay threshold was used to evaluate whether the management was cost-effective. Extensive sensitivity, subgroup, and scenario analyses were performed to address uncertainty. The US and UK population using race-specific cardiovascular risk models were conducted in the generalizability analysis. Data for the STEP trial were collected from February 10 to March 10, 2022, and were analyzed for the present study from March 10 to May 15, 2022. Hypertension treatments with a systolic blood pressure target of 110 to 130 mm Hg or 130 to 150 mm Hg. Incremental lifetime quality-adjusted life-years (QALYs), costs, and ICER are discounted at the given rates annually. After simulating 10 000 STEP-eligible patients assumed to be 66 years of age (4650 men [46.5%] and 5350 women [53.5%]) in the model, the ICER values were ¥51 675 ($12 362) per QALY gained in China, $25 417 per QALY gained in the US, and £4679 ($7004) per QALY gained in the UK. Simulations projected that the intensive management in China being cost-effective were 94.3% and 100% below the willingness-to-pay thresholds of 1 time (¥89 300 [$21 364]/QALY) and 3 times (¥267 900 [$64 090]/QALY) the gross domestic product per capita, respectively. The US had 86.9% and 95.6% probabilities of cost-effectiveness at $50 000/QALY and $100 000/QALY, respectively, and the UK had 99.1% and 100% of probabilities of cost-effectiveness at £20 000 ($29 940)/QALY and £30 000 ($44 910)/QALY, respectively. In this economic evaluation, the intensive systolic blood pressure control in older patients produced fewer cardiovascular events and had acceptable costs per QALY gained, well below the typical willingness-to-pay thresholds. The cost-effective advantages of intensive blood pressure management in older patients were consistent over various clinical scenarios across different countries.

Upfront Advanced Radiotherapy and New Drugs for NSCLC Patients with Synchronous Brain Metastases: Is the Juice Worth the Squeeze? A Real-World Analysis from Lombardy, Italy

Healthcare administrative databases represent a valuable source for real-life data analysis. The primary aim of this study is to compare effectiveness and cost profile in non-small-cell lung cancer (NSCLC) patients harboring synchronous brain metastases (BMs) who received non-chemo first-line systemic therapy with or without advanced radiotherapy (aRT). Diagnostic ICD-9-CM codes were used for identifying all patients with a new diagnosis of lung cancer between 2012 and 2019. Among these, patients who had started a first-line systemic treatment with either TKIs or pembrolizumab, alone or in combination with intensity-modulated or stereotactic RT, were selected. Clinical outcomes investigated included overall survival (OS), progression-free survival (PFS), and time-to-treatment failure (TTF). The cost outcome was defined as the average per capita cumulative healthcare direct costs of the treatment, including all inpatient and outpatient costs. The final cohort included 177 patients, of whom 58 were treated with systemic treatment plus aRT (STRT) and 119 with systemic treatment alone. The addition of aRT to systemic treatment was associated with a significantly better OS (p = 0.020) and PFS (p = 0.041) than systemic therapy alone. The ICER (incremental cost-effectiveness ratio) value indicated an average cost of €3792 for each month of survival after STRT treatment and confirmed clinical effectiveness but higher healthcare costs. This real-world study suggests that upfront aRT for NCLSC patients with synchronous BMs represents a valid treatment strategy, boosting the efficacy of novel and emerging drug classes with sustainable costs for the health service. The present real-world study reports that the use of upfront advanced radiotherapyaRT and new-generation systemic agents, such as TKIs and pembrolizumab, may have higher oncological control and an improved cost-effectiveness profile than the use of new-generation systemic agents alone in NCLSC patients with synchronous brain metastases. Acquired evidence can also be used to inform policymakers that adding advanced radiotherapy results is a sustainable cost for the health service. Since approximately 50% of patients do not meet RCT inclusion criteria, a significant proportion of them is receiving treatment that is not evidence-informed; therefore, these results warrant further studies to identify the best radiotherapy timing and possible dose escalation approaches to improving treatment efficacy in patient subgroups not typically represented in randomized controlled trials.

AW-NI-5: COST-EFFECTIVENESS OF INTENSIVE VERSUS STANDARD BLOOD-PRESSURE CONTROL AMONG HYPERTENSIVE PATIENTS IN TAIWAN: A SIMULATION MODELLING STUDY

Objective: Based on the Strategy of Blood Pressure Intervention in the Elderly Hypertensive Patients (STEP) trial and A Randomized Trial of Intensive versus Standard Blood-Pressure Control (SPRINT) trial, the 2022 Taiwan hypertension guidelines recommend the definition of hypertension as 130/80mmHg and a universal BP target of < 130/80 mmHg. Based on the guidelines, we aimed to analyze the lifetime cost-effectiveness of intensive versus standard blood-pressure control from the perspective of Taiwan national payer. Design and method: A simulation model was employed to apply the SPRINT treatment effects for hypertensive patients aged 50–54 and 55–64 years and STEP treatment effects for those aged 65–74 and 75+ years. The medical costs and utility were extracted from national sources or published data to a hypothetical cohort of SPRINT-eligible and STEP-eligible patients in Taiwan. Incremental cost-effectiveness ratio (ICER) against the willing-to-pay threshold at the one-time gross domestic product (GDP) per capita was used to evaluate whether intensive versus standard blood-pressure control was cost-effective. Results: Intensive blood-pressure control produced more lifetime medical costs than standard control, i.e., US$39,348–22,978 versus US$20,239–33,414, while intensive treatment also contributed to more quality-adjusted life-year (QALY), i.e., 7.60–16.28 versus 7.37–15.74. ICER values of intensive versus standard treatment were approximate US$10,989 (NT$329,670), US$11,220(NT$336,600), US$11,485(NT$344,550), and US$11,865(NT$355,950) per QALY gained for hypertensive patients aged 50–54, 55–64, 65–74, and 75+ from the perspective of Taiwanese national payer. Simulation results indicated that intensive treatment is very likely to be cost-effective, i.e., all probabilities are greater than 99.8% below the willing-to-pay threshold of US$36,000 (NT$1,080,000). Conclusions: In this simulation study, intensive blood-pressure control in the Taiwanese population produced fewer cardiovascular events and acceptable costs per QALY gained, enormously below the willing-to-pay threshold. The cost-effectiveness of intensive blood-pressure control was consistent across different ages, and the advantage was more predominant in younger hypertensive patients.

Cost-effectiveness analysis of androgen deprivation therapy with relugolix for the treatment of advanced prostate cancer

BackgroundRelugolix treatment of advanced prostate cancer (APC), like other gonadotropin-releasing hormone-antagonists, results in rapid decrease in testosterone concentrations without the risk of flare, as seen in leuprolide. Despite this benefit over leuprolide, no economic evaluation assessment to ascertain the cost-effectiveness of relugolix has been conducted. Therefore, this study aims to assess the cost-effectiveness of androgen deprivation therapy (ADT) with 120 mg relugolix against 7.5 mg leuprolide for the treatment of APC. MethodsA Markov model was used to assess and compare the costs of APC treatment from a health care payer's perspective and the effectiveness of ADT with relugolix and leuprolide at the 3 lines of APC treatment among modified intent-to-treat patients. Relative progression-free (PFS) and overall survival (OS) rates were estimated. Outcomes measured in the analyses included costs of the drugs and therapies, quality-adjusted life-years (QALYs), incremental cost-effectiveness ratios (ICERs), cost-effectiveness acceptability, and probability curves. ResultsThe cost-effectiveness analysis showed the ICER for ADT with relugolix to be US $49,571.1 per QALY. At the ICER value, the sensitivity analysis indicated that ADT with leuprolide was dominant in 100% of the simulations. ADT acceptance with relugolix was 100% when a willingness-to-pay threshold was set at US $100,000/QALY. At 5-years, the relative PFS and OS rates for relugolix at the first line of therapy were 72.7% and 86.0%, respectively, compared to 61.0% and 85.90% for leuprolide. ConclusionThough the influence of adverse events was not considered in the analysis, ADT with relugolix was not a cost-effective choice for APC management. While the analysis revealed a slight chance of sustaining testosterone suppression with relugolix, ADT with relugolix provided no significant survival advantages over ADT with leuprolide. Therefore, this analysis confirms no need for further assessment of APC interventions to make informed decisions beneficial to the APC patients, oncologists, and other stakeholders.

PP94 Exploring The Relationship Between Price And Outcome Of The Health-Economic Assessment In Japan

IntroductionThis study reviewed all publicly available Japanese cost-effectiveness appraisals delivered by the Center for Outcomes Research and Economic Evaluation for Health (C2H) from the national institute of public health (NIPH) and analyzed the relationship between the outcomes of the health-economic assessments and the final price adjustment decisions made by the Ministry of Health, Labour and Welfare (MHLW).MethodsData were extracted from all official health-economic assessments published by C2H website for the analysis. The extractions were structured based on the following items: indication, assessment methodology, appropriate comparators, health-economic outcomes, and key uncertainties identified by C2H. The analysis was performed on 29th November 2021. A threshold of 5 million JPY per Quality Adjusted Life Year gained (JPY/QALY) was used for the incremental cost-effectiveness ratio (ICER) analysis cut-off.ResultsUp to the time of this analysis, six health-economic assessments had been conducted for five products: three assessments performed cost-effectiveness analysis, one performed cost-minimization analysis and two performed cost-effectiveness and cost-minimization analysis for different comparators and different patient subgroups respectively. Among the five assessments’ reported ICER values, four of them are under the 5 million JPY/QALY threshold, ranging from 328,585 JPY/QALY to 483,056 JPY/QALY. However, price adjustments were still implemented on three out of the four products which were deemed to be cost-effective, ranging from -0.5 percent to -4.3 percent (mean: -3.0%). For the only product deemed to be not cost-effective, a price adjustment of -4.3 percent was implemented.ConclusionsA price discount could be implemented regardless of whether the ICER value falls under the 5 million JPY/QALY threshold. However, a lower magnitude of price discount is likely to be applied by MHLW for more cost effective treatments. The outcome of this analysis may be limited by the small sample size and continuous monitoring of further HTA publications in Japan is needed.

Oral Anticoagulants for Stroke Prevention in Atrial Fibrillation: A Systematic Review of Economic Evaluations

Several studies have evaluated the economic evaluation of a group of medications known as novel oral anticoagulant drugs (NOACs) in recent years. The aim of this study is to review and systematically analyze the cost-utility studies results of warfarin compared with other NOAC drugs in atrial fibrillation patients. A systematic review was performed to identify all studies evaluating the NOAC medications in comparison with warfarin. For this purpose, PubMed, Cochrane Library, ISI Web of Science, and Scopus were searched from 2013 to 2022. Articles were independently screened with inclusion criteria, and full texts were reviewed. First, the Consolidated Health Economic Evaluation Reporting Standards checklist was used to evaluate the quality of the articles. Then, the costs and outcomes of the studies were analyzed, and findings were appraised critically. A total of 84 costs-per-quality-adjusted life-year (QALY) cases were extracted from the studies in which the share of rivaroxaban, edoxaban, apixaban, and dabigatran were 31%, 13%, 29%, and 27%, respectively. The median cost per QALY of rivaroxaban, edoxaban, apixaban, and dabigatran was 21 910$/QALY, 22 096$/QALY, 17 765$/QALY, and 24 161$/QALY, respectively. Subgroup analysis based on perspective showed that dabigatran had the highest incremental cost-effectiveness ratio (ICER) and edoxaban had the lowest ICER value. Edoxaban and apixaban had the highest and the lowest cost per QALY from an insurance perspective, respectively. Despite the differences and variations in the economic evaluation studies of NOAC drugs, these drugs have shown acceptable cost-effectiveness in developed and developing countries. Among NOAC drugs, apixaban has the lowest ICER and the highest cost-effectiveness.

Cost-Effectiveness Analysis of Frontline Treatment with Polatuzumab Vedotin in Diffuse Large B-Cell Lymphoma

Introduction: The POLARIX trial (NCT03274492) recently demonstrated that substituting polatuzumab vedotin (pola), a CD79b-targeted antibody-drug conjugate, for vincristine in standard R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone) chemoimmunotherapy for first-line therapy can prolong progression-free survival in patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL). However, the medication cost of pola-R-CHP (pola, rituximab, cyclophosphamide, doxorubicin, and prednisolone) regimen is substantially higher than that of R-CHOP treatment. It remains unknown whether the lower rate of treatment failure with pola-R-CHP can be translated into reduced subsequent healthcare costs, increased life years (LYs), and improved quality of life, which may offset the higher medication cost. This study aimed to investigate the cost-effectiveness of substituting pola for vincristine in first-line therapy for patients with newly diagnosed DLBCL from a US payer perspective. Methods: We developed a decision analytic model to project lifetime quality-adjusted life years (QALYs) gained, LYs gained, and direct healthcare costs in newly diagnosed DLBCL patients. The model utilized a hypothetical cohort of patients at 65 years (the median age of disease onset). Direct healthcare costs were adjusted to 2021 US dollars, and an annual rate of 3% was used to discount future costs and benefits. Incremental cost-effectiveness ratios (ICERs) were calculated, and a willingness-to-pay (WTP) threshold of USD 150,000 per QALY gained was used as the acceptable level for determining cost-effectiveness. Sensitivity analyses and scenario analyses were conducted to assess the uncertainty of the base-case scenario and input parameters. Results: Pola-R-CHP, compared to standard R-CHOP, was associated with an incremental cost of USD 90,439, an improvement of 0.89 QALYs and 1.14 LYs, leading to an ICER of USD 101,510/QALY. The model was most sensitive to the survival benefit provided by pola-R-CHP, the age of the patients at initial treatment, and the price of pola. The ICER would increase significantly if pola-R-CHP is ineffective in providing long-term remissions. Furthermore, the ICER value increased as patients were older at the beginning of the treatment. When patients were older than 76.5 years at initial treatment, the ICER would exceed the WTP threshold of USD 150,000/QALY. To make the pola-R-CHP regimen cost-effective in all age groups (up to 80 years old), the current price of pola, which was estimated to be USD 19,307 for 170 mg per treatment cycle, needed to be reduced by 20%. In the probabilistic sensitivity analysis, 48% and 73% of the iterations produced ICERs below WTP thresholds of USD 100,000/ QALY and USD 150,000/ QALY, respectively. Conclusion: Our study findings suggest that pola-R-CHP, compared to the standard R-CHOP regimen, could be a cost-effective strategy in treatment-naïve DLBCL patients aged 65 years from a US payer perspective. However, several noticeable factors that could affect the cost-effectiveness profile of pola-R-CHP therapy should be considered in decision-making. The follow-up period of the POLARIX trial was relatively short, and mature survival data would be required to fully evaluate the value of pola in the treatment of newly diagnosed DLBCL.

Economic evaluation of three dialysis methods in patients with end-stage renal disease in China.

End-stage renal disease (ESRD) may result in different degrees of physical and psychological pain. Automated peritoneal dialysis (APD), continuous ambulatory peritoneal dialysis (CAPD), and hemodialysis (HD) as the main treatment methods lead to a heavy burden on social economic and family financial. However, there are few studies on the economic evaluation of the three dialysis methods in China. Cost-effectiveness analyses were performed using Markov models based on longitudinal data for 15years of different modalities in Kunshan City, China. Direct cost derived from medical insurance information system, and indirect cost referred to as loss of productivity. Sensitivity analyses were conducted to study uncertainty. The per capita total cost of CAPD was 664,027.00 yuan, the per capita utility is 5.9105. The per capita total cost of APD was 858,800.65 yuan, the per capita utility is 6.4548. The per capita total cost of HD was 1,281,213.64 yuan, the per capita utility is 6.1356. When CAPD was compared with HD, Incremental Cost-Effectiveness Ratio (ICER) was 1,323,389.53 yuan per QALY, compared with APD, ICER was 357,848.13 yuan per QALY. ICER value suggests that APD was cost-effective compared with CAPD and HD at a willingness-to-pay threshold of 538,200 yuan. Our research showed that APD is the most appropriate and HD is the worst in terms of cost-effectiveness. However, in fact, HD accounts for a high proportion in China, so some relevant policy suggestions need to be implemented to change the current situation.

Cost-Effectiveness of Pediatric Universal Screening for Familial Hypercholesterolemia in Argentina

ObjectiveOur study aimed to evaluate the expected cost-effectiveness of pediatric universal screening for the early diagnosis of familial hypercholesterolemia in Argentina using a probabilistic model. MethodsTwo different healthcare technologies were compared: (1) Universal screening of hypercholesterolemia at 6 years of age and (2) previous diagnostic situation (comparator). The perspective of the public Argentine healthcare system funded by the National Ministry of Health was used, considering only direct costs. Effectiveness was evaluated in terms of the number of life-years gained (LYG) and quality-adjusted life-years (QALYs) obtained by identifying familial hypercholesterolemia through each of the screening strategies. Only direct costs of screening and treatment of each strategy were evaluated. The time horizon was extended to 60 years. Future avoided costs of prevented coronary events were also included. Cost-effectiveness was measured in terms of the incremental cost-effectiveness ratio (ICER) per LYG and QALYs. Different scenarios were evaluated: (1) only index case, (2) index case and first-degree relatives, and (3) index case and first-degree relatives measuring QALYs. Sensitivity studies were conducted. ResultsEach identified child complying with follow-up visits and treatment gains 8.14 life-years. The ICER values obtained were 1465.35 USD/LYG and 1726.50 USD/LYG when applying a discount rate of 5%. The ICER was 10%-17% of the gross domestic product per capita in Argentina (mean 2010-2019: 12 446 USD) and did not exceed the minimum annual retirement income. ConclusionPediatric universal screening for familial hypercholesterolemia could be considered a cost-effective health technology in Argentina.

Rapid Review of Real-World Cost-Effectiveness Analyses of Cancer Interventions in Canada.

Cost-effectiveness analysis (CE Analysis) provides evidence about the incremental gains in patient outcomes costs from new treatments and interventions in cancer care. The utilization of “real-world” data allows these analyses to better reflect differences in costs and effects for actual patient populations with comorbidities and a range of ages as opposed to randomized controlled trials, which use a restricted population. This rapid review was done through PubMed and Google Scholar in July 2022. Relevant articles were summarized and data extracted to summarize changes in costs (in 2022 CAD) and effectiveness in cancer care once funded by the Canadian government payer system. We conducted statistical analyses to examine the differences between means and medians of costs, effects, and incremental cost effectiveness ratios (ICERs). Twenty-two studies were selected for review. Of those, the majority performed a CE Analysis on cancer drugs. Real-world cancer drug studies had significantly higher costs and effects than non-drug therapies. Studies that utilized a model to project longer time-horizons saw significantly smaller ICER values for the treatments they examined. Further, differences in drug costs increased over time. This review highlights the importance of performing real-world CE Analysis on cancer treatments to better understand their costs and impacts on a general patient population.

Economic evaluation of first-line nivolumab plus cabozantinib for advanced renal cell carcinoma in China.

BackgroundIn the Checkmate9ER trial, first-line treatment with nivolumab combined with cabozantinib (NI + CA) has shown efficacy for advanced renal cell carcinoma. This study aims to evaluate the impact of the health and economic outcomes of NI + CA in China.MethodsClinical efficacy data were derived from pivotal phase III CheckMate 9ER trial. A three-state partitioned survival model was established based on disease progression. Progression-free survival and overall survival of NI + CA vs. sunitinib were fitted with log-logistic and log-normal distributions, respectively. Mixture cure, non-mixture cure, and Royston/Parmar spline models were used to evaluate model robustness. The results derived the computational cost from the Chinese healthcare system perspective. The primary outcomes were quality-adjusted life-years (QALYs), total cost in US dollars, as well as incremental cost-effectiveness ratios (ICERs) at the willingness-to-pay threshold in China. One-way and probabilistic sensitivity analysis were also used to assess the robustness of the model.ResultsIn the base-case analysis result, 0.86 additional QALYs could be obtained in the NI+CA (3.84 QALYs) versus the sunitinib strategy (2.97 QALYs). The ICER of NI+CA compared with the sunitinib strategy was US$292,945 per QALY. The ICER value in the NI+CA strategy was higher than the Chinese willingness-to-pay threshold of US$38,024 per QALY. Although NI+CA can improve long-term patient survival significantly over sunitinib in the treatment of advanced renal cell carcinoma, it is unlikely to be cost-effective due to high cost. The results of the one-way sensitivity analysis showed that drug cost, health utility value at the stage of disease progression, and subsequent treatment proportion had a greater impact on the stability of ICER values.ConclusionsNivolumab combined with cabozantinib can prolong the life of patients with advanced renal cell carcinoma and improve their quality of life, but there is a corresponding increase in medical cost. The NI + CA strategy is unlikely to be considered cost-effective in the treatment of advanced RCC from the perspective of Chinese healthcare system.

Cost-effectiveness analysis of metformin and metformin-glimepiride in patients with type 2 diabetes at nene mallomo sidrap general hospital

Metformin and metformin-glimepiride are cost-effective therapy options and are most commonly prescribed to treat type 2 diabetes mellitus (DM). This study aims to determine the cost-effectiveness of using metformin and metformin-glimepiride in patients with type 2 DM at Nene Mallomo Sidenreng Rappang General Hospital. This analytical descriptive observational research employed a retrospective cohort design. The data of type 2 DM patients, new and old patients, were obtained from the medical record unit. The target population was data of outpatients for the period January-December 2019. The parameter of the therapeutic effectiveness is the random blood sugar levels of the patients after receiving treatment. The data on cost from the hospital perspective were obtained from the administration and finance unit. Cost-effectiveness analysis employed calculations of the average cost-effectiveness ratio (ACER) and the incremental cost-effectiveness ratio (ICER). Meanwhile, the risk ratio (RR) employed the analytical chi-squared method to determine the relationship between the two types of therapies and their effectiveness. This study has revealed that 30 patients met the inclusion criteria; 14 patients received metformin therapy and 16 patients received metformin-glimepiride therapy. Metformin therapy is more effective (64.29%) and more costly (IDR120,736). The metformin's ACER value is 1877.99, and its ICER value is -3107.26. The cost-effectiveness analysis has revealed that metformin therapy is more cost-effective than metformin-glimepiride therapy. Meanwhile, the chi-squared analysis has discovered no relationship between the two therapies and their effectiveness. The RR value of 1.080 concludes that metformin has 1.080 as much therapeutic effectiveness as the metformin-glimepiride.

Cost-effectiveness analysis of colonoscopy and fecal immunochemical testing for colorectal cancer screening in China.

ObjectiveThis study aimed to evaluate the cost-effectiveness of the colorectal cancer screening in China, and that when the screening was implemented in a specific region.MethodsA 13-state Markov model was established to compare four screening protocols, including annual fecal immunochemical testing (FIT1), biennial fecal immunochemical testing (FIT2), electronic colonoscopy every 10 years (e-CSPY10), and electronic colonoscopy every 5 years (e-CSPY5), with no screening from the perspective of Chinese healthcare system. The model simulated the health states of a cohort of 100,000 average-risk individuals aging from 50 to 75. Additionally, scenarios including the implementation in a specific region, starting from 40, and incompletely successful treatment of cancer were also analyzed.ResultsAnnual and biennial FIT could save 8.13USD (US Dollar) and 44.96USD per person, and increase 0.0705QALYs (Quality-Adjusted Life Years) and 0.2341 QALYs compared with no screening, respectively. Annual FIT could decrease costs by 36.81USD per person and increase 0.1637 QALYs in comparison to biennial FIT. The results showed that both annual and biennial FIT for screening were dominant over no screening, and annual FIT was dominant over biennial FIT. The ICER (Incremental Cost-Effectiveness Ratio) for e-CSPY10 were 1183.51USD/QALY and 536.66USD/QALY compared with FIT1 and FIT2. The ICER for e-CSPY5 were 1158.16USD/QALY and 770.85USD/QALY compared with FIT1 and FIT2. And the ICER for e-CSPY5 relative to e-CSPY10 was 358.71USD/QALY. All the ICER values were lower than the economic threshold of 2021 Chinese GDP (Gross Domestic Product) per capita in 2021(12554.42USD).ConclusionsIt is worthwhile to popularize CRC screening in mainland China, as FIT always saving costs and colonoscopy is cost-effective. Regions with high income can take electronic colonoscopy every 10 years, or even every 5 years into consideration when determining the specific strategies.

Trastuzumab biosimilar HLX02 versus reference trastuzumab in patients with recurrent or metastatic HER2-positive breast cancer: a model-based economic evaluation for China

ABSTRACT Background HLX02 is a newly marketed trastuzumab biosimilar in China, but whether its price reflects a potential benefit in terms of its value remains unclear. In addition, the development of biosimilars in China is just beginning, and the state encourages health economic evaluation of newly marketed biosimilars. Methods Based on the previously published randomized controlled trial data, a Markov model was used to perform health economic evaluation of HLX02 and trastuzumab in the treatment of HER2-positive recurrent or metastatic breast cancer, calculate quality-adjusted life years (QALYs) and incremental cost-effectiveness ratio (ICER), and evaluate the robustness of the model with sensitivity analysis. Results The model results showed that the 5-year mortality rate was 84.4% in the HLX02 group, while the mortality rate was 91.2% in the trastuzumab group. When without accounting for the cost of second-line treatment, patients treated with HLX02 had an increased life expectancy of 0.138 QALYs and a $421.11 lower cost compared with patients in the trastuzumab group, with an ICER value of -$3,051.52/QALY. Conclusions At the willingness-to-pay threshold of $37,653/QALY in China, HLX02 is more cost-effective than trastuzumab. However, the relevant systems for the regulation of biosimilars still need to be improved.

Cost-effectiveness analysis of rhTPO and rhIL-11 in the treatment of chemotherapy-induced thrombocytopenia in hematological tumors based on real-world data

Chemotherapy-induced thrombocytopenia (CIT) is a common adverse reaction to chemotherapy that can lead to treatment delay, platelet transfusion, thereby increasing treatment costs, reducing chemotherapy effectiveness and affecting prognosis. Based on real-world data, this study analyzed the safety, efficacy, and economic of recombinant human thrombopoietin (rhTPO) and recombinant human interleukin-11 (rhIL-11) in the treatment of CIT in hematological tumors from the perspective of the health care system.We retrospectively collected the data of hematological tumor patients treated with rhTPO and rhIL-11 due to thrombocytopenia caused by chemotherapy. The propensity score matching (PSM) method was used to balance the baseline information of the two groups and they were further stratified according to the degree of thrombocytopenia (grade I-II and grade III-IV). The platelet compliance rate at 2 weeks of treatment was used as the efficacy evaluation index, and the cost-effectiveness method was used to evaluate the economic value of the two drugs in the treatment of thrombocytopenia based on drug effectiveness. Univariate and probabilistic sensitivity analyses were performed.A total of 1,571 patients met the inclusion and exclusion criteria, and 476 patients were included after 1:1 PSM. For patients with grade I-II thrombocytopenia, no significant difference in the platelet compliance rate was found between the two groups after 1 and 2 weeks of treatment. The platelet compliance rate in the rhTPO group was higher than that in the rhIL-11 group for patients with grade III-IV thrombocytopenia. Cost-effectiveness analysis (CEA) showed that the incremental cost-effectiveness ratio (ICER) for the rhTPO and rhIL-11 groups was 226,615.8. The ICER value was sensitive to the platelet compliance rate of the two groups, the cost of rhTPO, the cost of platelet transfusion in the rhTPO group. Probabilistic sensitivity analysis showed that when willingness to pay was less than approximately 220,000 yuan, rhIL-11 economy presented 100% better than that of rhTPO.In CIT treatment for hematological tumors, rhTPO yielded a higher platelet compliance rate than rhIL-11 treatment, especially for patients with grade III-IV thrombocytopenia. However, whether rhTPO has economic advantages still requires further exploration.

HTA52 Comparing the Change from Base Case to Re-Analyzed ICER Values for CADTH Oncology Evaluations

The CADTH reimbursement review process determines cost-effectiveness using the incremental cost-effectiveness ratio (ICER). CADTH makes three possible recommendations: reimburse (recommended), reimburse with conditions (conditionally recommended), and do not reimburse (not recommended). ICER values are reported exactly, as a range, or as dominant/dominated. This study determines the ICER change between the manufacturer submitted and CADTH reanalyzed values for oncology reviews, stratified by decision type.
