Tirzepatide 10 and 15 mg vs semaglutide 2.0 mg: A long-term cost-effectiveness analysis in patients with type 2 diabetes in the United States.

Tirzepatide is a novel glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 receptor agonist approved for type 2 diabetes (T2D) treatment. To compare the long-term cost-effectiveness of tirzepatide 10 mg and 15 mg vs semaglutide 2.0 mg, an injectable glucagon-like peptide-1 receptor agonist, in patients with T2D from a US health care payer perspective. The PRIME T2D Model was used to project clinical and cost outcomes over a 50-year time horizon. Baseline cohort characteristics and treatment effects were sourced from a published adjusted indirect treatment comparison that used data from the SURPASS-2 and SUSTAIN FORTE trials. Patients were assumed to intensify to insulin therapy at a hemoglobin A1c of greater than 7.5%. Costs and health state utilities were derived from published sources. Future costs and clinical benefits were discounted at 3% annually. Tirzepatide 10 mg and 15 mg were associated with improved quality-adjusted life-expectancy (10 mg: 0.085 quality-adjusted life-years [QALYs], 15 mg: 0.121 QALYs), higher direct costs (10 mg: USD 5,990, 15 mg: USD 6,617), and incremental cost-effectiveness ratios of USD 70,147 and 54,699 per QALY gained, respectively, vs semaglutide 2.0 mg. Both doses of tirzepatide remained cost-effective vs semaglutide 2.0 mg over a range of sensitivity analyses. Long-term projections using the PRIME T2D model and based on treatment effects from an adjusted indirect treatment comparison indicate that tirzepatide 10 mg and 15 mg are likely to be cost-effective vs semaglutide 2.0 mg for the treatment of T2D in the United States.

Length of stay and discharge dispositions following robotic arm-assisted total knee arthroplasty and unicompartmental knee arthroplasty versus conventional technique and predictors of delayed discharge.

In-hospital length of stay (LOS) and discharge dispositions following arthroplasty could act as surrogate measures for improvement in patient pathways, and have major cost saving implications for healthcare providers. With the ever-growing adoption of robotic technology in arthroplasty, it is imperative to evaluate its impact on LOS. The objectives of this study were to compare LOS and discharge dispositions following robotic arm-assisted total knee arthroplasty (RO TKA) and unicompartmental arthroplasty (RO UKA) versus conventional technique (CO TKA and UKA). This large-scale, single-institution study included patients of any age undergoing primary TKA (n = 1,375) or UKA (n = 337) for any cause between May 2019 and January 2023. Data extracted included patient demographics, LOS, need for post anaesthesia care unit (PACU) admission, anaesthesia type, readmission within 30 days, and discharge dispositions. Univariate and multivariate logistic regression models were also employed to identify factors and patient characteristics related to delayed discharge. The median LOS in the RO TKA group was 76 hours (interquartile range (IQR) 54 to 104) versus 82.5 (IQR 58 to 127) in the CO TKA group (p < 0.001) and 54 hours (IQR 34 to 77) in the RO UKA versus 58 (IQR 35 to 81) in the CO UKA (p = 0.031). Discharge dispositions were comparable between the two groups. A higher percentage of patients undergoing CO TKA required PACU admission (8% vs 5.2%; p = 0.040). Our study showed that robotic arm assistance was associated with a shorter LOS in patients undergoing primary UKA and TKA, and no difference in the discharge destinations. Our results suggest that robotic arm assistance could be advantageous in partly addressing the upsurge of knee arthroplasty procedures and the concomitant healthcare burden; however, this needs to be corroborated by long-term cost-effectiveness analyses and data from randomized controlled studies.

Calibration of the IQVIA Core Diabetes Model to the stroke outcomes from the SUSTAIN 6 cardiovascular outcomes trial of once-weekly semaglutide

AimsIn the SUSTAIN 6 cardiovascular outcomes trial, once-weekly semaglutide was associated with a statistically significant reduction in major adverse cardiovascular events compared with placebo. To date, no studies have assessed how accurately existing diabetes models predict the outcomes observed in SUSTAIN 6. The aims of this analysis were to investigate the performance of the IQVIA Core Diabetes Model when used to predict the SUSTAIN 6 trial outcomes, to calibrate the model such that projected outcomes reflected observed outcomes, and to examine the impact of calibration on the cost-effectiveness of once-weekly semaglutide from a UK healthcare payer perspective.MethodsThe IQVIA Core Diabetes Model was calibrated to ensure that the projected non-fatal stroke event rates reflected the non-fatal stroke event rates observed in SUSTAIN 6 over a two-year time horizon. Cost-effectiveness analyses of once-weekly semaglutide versus placebo plus standard of care were conducted over a lifetime horizon using the uncalibrated and calibrated models to assess the impact on cost-effectiveness outcomes.ResultsTo replicate the non-fatal stroke event rate in SUSTAIN 6, calibration of the model through the application of relative risks for stroke of 1.07 and 1.65 with once-weekly semaglutide and placebo, respectively, was required. In the long-term cost-effectiveness analysis, the uncalibrated model projected an incremental cost-effectiveness ratio for once-weekly semaglutide versus placebo plus standard of care of GBP 22,262 per quality-adjusted life year (QALY) gained, which fell to GBP 17,594 per QALY gained when the calibrated model was used.ConclusionsThe requirement for calibration to replicate the outcomes observed in SUSTAIN 6 suggests that the reductions in risk of cardiovascular complications observed with once-weekly semaglutide cannot be solely explained by differences in conventional risk factors. Accurate estimation of the risk of diabetes-related complications using methods such as calibration is important to ensure accurate cost-effectiveness analyses are conducted.

Long-term cost-effectiveness analysis of sacral neuromodulation in the treatment of severe faecal incontinence.

The aim of this study was to evaluate the long-term cost-effectiveness of sacral neuromodulation in the treatment of severe faecal incontinence as compared with symptomatic management. In the public health field, a micro-costing evaluation method was conducted from the perspectives of the health system and the society. The incremental cost-effectiveness ratio was used as a decision index, and we considered various scenarios to evaluate the impact of the cost of symptomatic management and percutaneous nerve evaluation success rate in its calculation. Clinical data were retrieved from a consecutive cohort of 93 patients with severe faecal incontinence undergoing sacral neuromodulation after a failure of conservative (pharmacological and biofeedback) and/or surgical (sphincteroplasty) first-line treatments were considered. The long-term incremental cost-effectiveness ratio comparing sacral neuromodulation versus symptomatic management was 14347€/QALY and 28523€/QALY from the societal and health service provider's perspectives, respectively. If the definitive pulse generator implant success rate was 100%, incremental cost-effectiveness would correspond to 6831€/QALY and 16761€/QALY, respectively. Sacral neuromodulation may be considered a cost-effective technique in the long-term treatment of severe faecal incontinence from the societal and health care sector perspectives. Improving patient selection and determining the predictive outcome factors for successful sacral neuromodulation in the treatment of faecal incontinence would improve cost-effectiveness.

LENGTH OF STAY AND DISCHARGE DISPOSITION FOLLOWING ROBOTIC ARM-ASSISTED TOTAL HIP ARTHROPLASTY VERSUS CONVENTIONAL TECHNIQUE AND PREDICTORS OF DELAYED DISCHARGE

In-hospital length of stay (LOS) and discharge disposition following arthroplasty could act as surrogate measures for improvement in patient pathways, and have major cost saving implications for healthcare providers. With the ever-growing adoption of robotic technology in arthroplasty, we wished to evaluate its impact on LOS. The objectives of this study were to compare LOS and discharge disposition following robotic-arm assisted (RO THA) versus conventional technique Total Hip Arthroplasty (CO THA).This large-scale, single institution study included patients of any age undergoing primary THA (N = 1,732) for any cause between May 2019 and January 2023. Data extracted included patient demographics, LOS, need for Post Anaesthesia Care Unit (PACU) admission, anaesthesia type, readmission within 30 days and discharge dispositions. Univariate and multivariate logistic regression models were also employed to identify factors and patient characteristics related to delayed discharge.The median LOS in the RO THA group was 54 hours (34, 78) versus 60 (51, 100) in the CO THA group, p&lt;0.001. Discharge disposition was comparable between the two groups. In the multivariate model, age, need for PACU admission, ASA score &gt; 2, female gender, general anaesthesia and utilisation of the conventional technique were significantly associated with LOS &gt; 2 days.Our study showed that robotic-arm assistance was associated with a shorter LOS in patients undergoing primary THA and no difference in discharge destination. Our results suggest that robotic-arm assistance could be advantageous in partly addressing the upsurge of hip arthroplasty procedures and the concomitant health care burden; however, this needs to be corroborated by long-term cost effectiveness analyses and data from randomised controlled studies.

Cost-effectiveness of tenecteplase versus alteplase for stroke thrombolysis evaluation trial in the ambulance.

Tenecteplase administered to patients with ischaemic stroke in a mobile stroke unit (MSU) has been shown to reduce the perfusion lesion volumes and result in ultra-early recovery. We now seek to assess the cost-effectiveness of tenecteplase in the MSU. A within-trial (TASTE-A) economic analysis and a model-based long-term cost-effectiveness analysis were performed. This post hoc within-trial economic analysis utilised the patient-level data (intention to treat, ITT) prospectively collected over the trial to calculate the difference in both healthcare costs and quality-adjusted life years (QALYs, estimated from modified Rankin scale score). A Markov microsimulation model was developed to simulate the long-term costs and benefits. In total, there were 104 patients with ischaemic stroke randomised to tenecteplase (n = 55) or alteplase (n = 49) treatment groups, respectively in the TASTE-A trial. The ITT-based analysis showed that treatment with tenecteplase was associated with non-signficantly lower costs (A$28,903 vs A$40,150 (p = 0.056)) and greater benefits (0.171 vs 0.158 (p = 0.457)) than that for the alteplase group over the first 90 days post the index stroke. The long-term model showed that tenecteplase led to greater savings in costs (-A$18,610) and more health benefits (0.47 QALY or 0.31 LY gains). Tenecteplase-treated patients had reduced costs for rehospitalisation (-A$1464), nursing home care (-A$16,767) and nonmedical care (-A$620) per patient. Treatment of ischaemic stroke patients with tenecteplase appeared to be cost-effective and improve QALYs in the MSU setting based on Phase II data. The reduced total cost from tenecteplase was driven by savings from acute hospitalisation and reduce need for nursing home care.

Cost-accuracy and patient experience assessment of blood pressure monitoring methods to diagnose hypertension: A comparative effectiveness study.

Studies of the diagnosis of hypertension have emphasized long-term cost-effectiveness analysis, but the patient experience and costs of blood pressure monitoring methods at the diagnosis stage remain unclear. We studied four diagnostic methods: a new 1 h-automated office blood pressure (BP) monitoring, office BP measurement, home BP monitoring, and awake-ambulatory BP monitoring. We carried out a comparative effectiveness study of four methods of diagnosing hypertension in 500 participants with a clinical suspicion of hypertension from three primary healthcare (PHC) centers in Barcelona city (Spain). We evaluated the time required and the intrinsic and extrinsic costs of the four methods. The cost-accuracy ratio was calculated and differences between methods were assessed using ANOVA and Tukey's honestly significant difference (HSD) post-hoc test. Patient experience data were transformed using Rasch analysis and re-scaled from 0 to 10. Office BP measurement was the most expensive method (€156.82, 95% CI: 156.18-157.46) and 1 h-automated BP measurement the cheapest (€85.91, 95% CI: 85.59-86.23). 1 h-automated BP measurement had the best cost-accuracy ratio (€ 1.19) and office BP measurement the worst (€ 2.34). Home BP monitoring (8.01, 95% CI: 7.70-8.22), and 1 h-automated BP measurement (7.99, 95% CI: 7.80-8.18) had the greatest patient approval: 66.94% of participants would recommend 1 h-automated BP measurement as the first or second option. The relationship between the cost-accuracy ratio and the patient experience suggests physicians could use the new 1 h-automated BP measurement as the first option and awake-ambulatory BP monitoring in complicated cases and cease diagnosing hypertension using office BP measurement.

A long-term cost-effectiveness analysis of cardiac resynchronisation therapy with or without defibrillator based on health claims data

BackgroundIn Germany, CRT devices with defibrillator capability (CRT-D) have become the predominant treatment strategy for patients with heart failure and cardiac dyssynchrony. However, according to current guidelines, most patients would also be eligible for the less expensive CRT pacemaker (CRT-P). We conducted a cost-effectiveness analysis for CRT-P devices compared to CRT-D devices from a German payer’s perspective.MethodsLongitudinal health claims data from 3569 patients with de novo CRT implantation from 2014 to 2019 were used to parametrise a cohort Markov model. Model outcomes were costs and effectiveness measured in terms of life years. Transition probabilities were derived from multivariable parametric survival regression that controlled for baseline differences of CRT-D and CRT-P patients. Deterministic and probabilistic sensitivity analyses were conducted.ResultsThe Markov model predicted a median survival of 84 months for CRT-P patients and 92 months for CRT-D patients. In the base case, CRT-P devices incurred incremental costs of € − 13,093 per patient and 0.30 incremental life years were lost. The ICER was € 43,965 saved per life year lost. In the probabilistic sensitivity analysis, uncertainty regarding the effectiveness was observed but not regarding costs.ConclusionThis modelling study illustrates the uncertainty of the higher effectiveness of CRT-D devices compared to CRT-P devices. Given the difference in incremental costs between CRT-P and CRT-D treatment, there would be significant potential cost savings to the healthcare system if CRT-D devices were restricted to patients likely to benefit from the additional defibrillator.

Long-Term Cost-Effectiveness Analysis of Once-Weekly Semaglutide versus Dulaglutide in Patients with Type 2 Diabetes with Inadequate Glycemic Control in China.

IntroductionThe objective of the current study was to assess the long-term cost-effectiveness of once-weekly semaglutide 0.5 mg and 1.0 mg versus dulaglutide 1.5 mg for the treatment of patients with type 2 diabetes uncontrolled on metformin in the Chinese setting.MethodsThe Swedish Institute of Health Economics Diabetes Cohort Model (IHE-DCM) was used to evaluate the long-term health and economic outcomes of once-weekly semaglutide and dulaglutide. Analysis was conducted from the perspective of the Chinese healthcare systems over a time horizon of 40 years. Data on baseline cohort characteristics and treatment effects were sourced from the SUSTAIN 7 clinical trial. Costs included treatment costs and costs of complications. Projected health and economic outcomes were discounted at a rate of 5% annually. The robustness of the results was evaluated through one-way sensitivity analyses and probabilistic sensitivity analyses.ResultsCompared with dulaglutide 1.5 mg, once-weekly semaglutide 0.5 mg and 1.0 mg were associated with improvements in discounted life expectancy of 0.04 and 0.10 years, respectively, and improvements in discounted quality-adjusted life expectancy of 0.08 and 0.19 quality-adjusted life years (QALYs), respectively. Clinical benefits were achieved at reduced costs, with lifetime cost savings of 8355 Chinese Yuan (CNY) with once-weekly semaglutide 0.5 mg and 11,553 CNY with once-weekly semaglutide 1.0 mg. Sensitivity analyses verified the robustness of the research results.ConclusionsOnce-weekly semaglutide was suggested to be dominant (more effective and less costly) versus dulaglutide 1.5 mg in patients with type 2 diabetes uncontrolled on metformin treatment in China.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13300-022-01301-4.

Economic evaluation of an incentive-based program to increase physical activity and reduce sedentary behaviour in middle-aged adults

BackgroundIncentive-based programs represent a promising approach for health insurers to encourage health-promoting behaviours. However, little is known about the value for money of such programs. This study aimed to determine the cost-effectiveness of the ACHIEVE (Active CHoices IncEntiVE) program designed to incentivise increased physical activity and reduced sedentary behaviour in middle-aged adults.Methods A within-trial cost-efficacy analysis was conducted. Benefits were assessed by evaluating paired t-tests from participants’ pre- and post- trial Body Mass Index (BMI) (kg/m2), sitting time (minutes/day) and metabolic equivalents (METS) minutes. A health sector perspective was adopted for the assessment of costs. Pathway analysis was used to determine the resource use associated with the intervention, with costs expressed in Australian dollars (A$) for the 2015 reference year. A long-term cost-effectiveness analysis was undertaken which extended the analysis time horizon and the trial population to the relevant eligible Australian population. Within this analysis, the 16-week intervention was modelled for roll-out across Australia over a 1-year time horizon targeting people with private health insurance who are insufficiently active and highly sedentary. Improved health related quality of life quantified in Health-Adjusted Life Years (HALYs) (based on the health impacts of increased metabolic equivalent (MET) minutes and reduced body mass index (BMI) and cost-offsets (resulting from reductions in obesity and physical inactivity-related diseases) were tracked until the cohort reached age 100 years or death. A 3% discount rate was used and all outcomes were expressed in 2010 values. Simulation modelling techniques were used to present 95% uncertainty intervals around all outputs.Results The within-trial cost-efficacy analysis indicated that the ACHIEVE intervention cost approximately A$77,432. The cost per participant recruited was A$944. The incremental cost-effectiveness ratio (ICER) for MET increase per person per week was A$0.61; minute of sedentary time reduced per participant per day was A$5.15 and BMI unit loss per participant was A$763. The long-term cost effectiveness analysis indicated that if the intervention was scaled-up to all eligible Australians, approximately 265,095 participants would be recruited to the program at an intervention cost of A$107.4 million. Health care cost savings were A$33.4 million. Total HALYs gained were 2,709. The mean ICER was estimated at A$27,297 per HALY gained which is considered cost-effective in the Australian setting.Conclusion The study findings suggest that financial incentives to promote physical activity and reduce sedentary behaviour are likely to be cost-effective.Trial registrationAustralian New Zealand Clinical Trials Registry: ACTRN12616000158460 (10/02/2016).

Cost-effectiveness analysis of continuous subcutaneous insulin infusion versus multiple daily insulin for treatment of children with type 1 diabetes

ABSTRACT Objective To evaluate the health economics of using continuous subcutaneous insulin infusion (CSII) therapy versus multiple daily injections (MDI) therapy in children and adolescent patients with type 1 diabetes (T1D) in Qingdao, China. Methods A long-term cost-effectiveness analysis was conducted using the IQVIA Core Diabetes Model (CDM). The baseline characteristics of the simulated cohorts were obtained from 213 pediatric T1D patients who received care with CSII(104 cases) or MDI(109 cases) in Qingdao from 1 January 2015 to 31 March 2019. In the essential case, the expenditure of the complications and treatment of the disease with both therapies were evaluated in Chinese currency from the perspective of healthcare system. In a secondary analysis, the model used a 70-year time horizon, and a discount rate of 5% was applied to all future health outcomes and costs. A one-way sensitivity analysis was conducted on delta HbA1c, different prices of insulin pump, price of each upgrade cycle rates and different discount rates. Uncertainty was also evaluated by the probability sensitivity analysis and scenario analysis. Results In the base-case analysis, the lifetime total costs were lower for CSII group at ¥630,871 per patient compared with ¥672,672 for MDI group. The quality-adjusted life years (QALYs) gained were 11.612 and 11.197 for patients treated with CSII group and MDI group, respectively. The CSII group was cost-saving compared to MDI group. The feasibility of CSII group being cost-effective was 100% under the threshold of 3 times per capita GDP of China in 2019 (¥212,676) which was indicated from the probabilistic sensitivity analysis. Regarding scenario analysis, the ICER of the CSII group compared to MDI was between −151,583 and 153,366 RMB/QALYs, which is cost-effective. Conclusions This economic evaluation compared CSII therapy versus MDI therapy for T1D children and adolescent patients in China and findings indicate that CSII should be considered a preferred treatment modality to MDI.

Computable Phenotype of a Crohn's Disease Natural History Model.

Analytic tools to study important clinical issues in complex, chronic diseases such as Crohn's disease (CD) include randomized trials, claims database studies, or small longitudinal epidemiologic cohorts. Using natural language processing (NLP), we sought to define the computable phenotype health state of pediatric and adult CD and develop patient-level longitudinal histories for health outcomes. We defined 6 health states for CD using a subjective symptom-based assessment (symptomatic/asymptomatic) and an objective disease state assessment (active/inactive/no testing). Gold standard for the 6 health states was derived using an iterative process during review by our CD experts. We calculated the transition probabilities to estimate the time to transitions between the various health states using nonparametric Kaplan-Meier estimation and a Markov model. Finally, we determined a standard utility measure from clinical patients assigned to different health states. The NLP computable phenotype health state model correctly ascertained the objective test results and symptoms 96% and 85% of the time, respectively, based on a blinded chart evaluation. In our model, >25% of patients who begin as asymptomatic/active transition to symptomatic/active over the following year. For both adult and pediatric CD health states, the utility assessments of a symptomatic/inactive health state closely resembled a symptomatic/active health state. Our methodology for a computable phenotype health state demonstrates the application of real-world data to define progression and optimal management of a chronic disease such as CD. The application of the model has the potential to lead to a better understanding of the true impact of a therapeutic intervention and can provide long-term cost-effectiveness analyses for a new therapy.

Cost-Effectiveness Analysis of Direct Oral Anticoagulants Versus Vitamin K Antagonists for Venous Thromboembolism in China.

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

Cost-Effectiveness Analysis of Prostate Cancer Screening in Brazil

Introduction: Prostate cancer is one of the most common malignancies among men worldwide. Prostate-specific antigen (PSA) screening shows uncertain benefits and harms from clinical and economic perspectives, resulting in an important impact on healthcare systems. Because of nonstandardized studies and substantial differences among populations, data are still inconclusive. ObjectiveThe objective of this study was to carry out long-term cost-effectiveness and cost-utility analysis on the PSA-screened population from the service provider’s perspective in the Brazilian population. MethodsWe performed a cost-effectiveness and cost-utility analysis using clinical outcomes obtained from 9692 men enrolled in the PSA screening program. Prostate cancer treatments, 5-year follow-up outcomes, and all related costs were examined. Data were compared with a nonscreened prostate cancer population to calculate incremental cost-effectiveness ratio (ICER) and incremental cost-utility ratio (ICUR). ICER and ICUR were compared with the Brazilian-established willingness-to-pay (WTP) threshold (WTP = R$ 114 026.55). ResultsA total of 251 of 9692 men had a diagnosis of prostate cancer (2.6%), of which 90% had localized disease. Two hundred and five patients were treated as follows: surgery (45.37%); radiation therapy (11.22%); radiation plus androgen deprivation therapy (21.95%); active surveillance (13.17%); exclusive androgen deprivation therapy (7.32%); and watchful waiting (0.98%). Two simulated cohorts were compared based on screening and nonscreening groups. Values obtained were—ICER of R$ 44 491.39 per life saved and ICUR of R$ 10 851.56 per quality-adjusted life year (QALY) gained—below the Brazilian WTP threshold and showed cost-effectiveness and cost-utility advantages. ConclusionAccording to the Brazilian WTP, PSA screening is a cost-effective policy from a hospital and long-term perspective and should have more standardized studies developed in different populations and economies.

The budget impact of lung cancer screening with low-dose computed tomography

Our earlier analysis indicated that screening lung cancer patients with low-dose computed tomography amongst smokers between age of 50-74 and between age of 55-74 is cost-effective and cost-saving, respectively. This study aims to extend the long-term cost-effectiveness analysis with short- and mid-term budget impact analysis. The health economic model compares the cost of nationwide screening amongst smokers between 50-74 years to the current occasional screening policy. The analysis determines the size of the target population, recruitment rates and market uptake. Health care finance costs associated with the patient pathways are determined by national guidelines and clinical practice. Screening and treatment effectiveness are based on the HUNCHEST survey and international scientific literature, while the cost of health states and events are determined using national tariffs. Assuming 10% uptake of low-dose computed tomography screening for the target population will cost an additional 3.3 billion HUF and 1.9 billion HUF in the 1st and 5th years, respectively. Until the 3rd year, new patients' treatment costs exceed costs due to late discovery and delay in treatment. This pattern is changing from the 4th year on. Due to timely care savings by the 10th year in the screened population will reduce total costs to the 20% of the first year costs. Introduction of national screening for lung cancer patients with low-dose computed tomography is estimated to cost around additional 2.6 billion HUF/year and could end up in net savings in the long run. Identification of risk groups according to regional or other strata could increase the effectiveness and efficiency of the program. Orv Hetil. 2021; 162(24): 952-959.

Short- and long-term cost-effectiveness analysis of CYP2C19 genotype-guided therapy, universal clopidogrel, versus universal ticagrelor in post-percutaneous coronary intervention patients in Qatar

BackgroundPatients having CYP2C19 loss-of-function alleles and receiving clopidogrel are at higher risk of adverse cardiovascular outcomes. Ticagrelor is an effective antiplatelet that is unaffected by the CYP2C19 polymorphism. The main aim of the current research is to evaluate the cost-effectiveness among CYP2C19 genotype-guided therapy, universal ticagrelor, and universal clopidogrel after a percutaneous coronary intervention (PCI). MethodsA two-part decision-analytic model, including a one-year model and a 20-year follow-up Markov model, was created to follow the use of (i) universal clopidogrel, (ii) universal ticagrelor, and (iii) genotype-guided antiplatelet therapy. Outcome measures were the incremental cost-effectiveness ratio (ICER, cost/success) and incremental cost-utility ratio (ICUR, cost/quality-adjusted life years [QALY]). Therapy success was defined as survival without myocardial infarction, stroke, cardiovascular death, stent thrombosis, and no therapy discontinuation because of adverse events, i.e. major bleeding and dyspnea. The model was based on a multivariate analysis, and a sensitivity analysis confirmed the robustness of the model outcomes, including against variations in drug acquisition costs. ResultsAgainst universal clopidogrel, genotype-guided therapy was cost-effective over the one-year duration (ICER, USD 6102 /success), and dominant over the long-term. Genotype-guided therapy was dominant against universal ticagrelor over the one-year duration, and cost-effective over the long term (ICUR, USD 1383 /QALY). Universal clopidogrel was dominant over ticagrelor for the short term, and cost-effective over the long-term (ICUR, USD 10,616 /QALY). ConclusionCYP2C19 genotype-guided therapy appears to be the preferred antiplatelet strategy, followed by universal clopidogrel, and then universal ticagrelor for post-PCI patients in Qatar.

Abstract 13636: Evolocumab Shows No Significant Cost-effectiveness for Myocardial Infarction in China

Introduction: The proprotein convertase subtilisin/kexin type 9 inhibitor evolocumab has been demonstrated to reduce the incidence of cardiovascular events. This study sought to evaluate the value of evolocumab in the healthcare perspective by conducting a long-term cost-effectiveness analysis in Chinese patients with myocardial infarction (MI). Hypothesis: We assessed the hypothesis that evolocumab was inefficient for the secondary prevention of MI. Methods: A Markov cohort state-transition model was developed in decision analysis software. The model subjects could have non-fatal MI and/or stroke events, as well as die from cardiovascular disease or other causes. We integrated Chinese population specific demographics and event rates with the risk reduction of evolocumab based on large trials and meta-analysis. Age-related change, event costs and utilities were included from published sources. The model had 1-year cycle and the time horizon was 25 years. The primary outcome was the incremental cost-effectiveness ratio (ICER), defined as cost per quality-adjusted life-year (QALY) saved. Results: At its current list price (33,748 CNY annually per person), the ICER was 927,713 CNY per QALY gained. In one-way deterministic sensitivity analyses, the ICER was closely associated with the utility of cardiovascular disease event free and the cost of cardiovascular death. Probabilistic sensitivity analyses demonstrated that the probability of the cost-effectiveness of evolocumab was 1.96% at the present willingness-to-pay threshold of 212,676 CNY per QALY gained. To achieve the cost-effectiveness threshold, a net value-based price of 10,255 CNY annually would be required, which is 70% lower than the present price. Alternative scenarios analyses of treatment benefit showed in MI patients with poorly controlled familial hypercholesterolemia (FH), the ICER for evolocumab was 187,736 CNY per QALY gained, which achieved the accepted cost-effectiveness threshold. Conclusions: In conclusion, the cost-effectiveness ratio of evolocumab is less favorable in MI; However, it showed good cost-effectiveness in MI patients with poorly controlled FH in China.

Sleeve gastrectomy or gastric bypass: a "post-code" lottery? A comprehensive national analysis of the utilization of bariatric surgery in Switzerland between 2011-2017.

Sleeve gastrectomy (SG) recently became the most frequently performed bariatric surgery (BS) worldwide, overtaking the long-time standard Roux-en-Y gastric bypass (RYGB). Main indications for one or the other procedure show large inter-center variations and warrant further investigations. The aim of this study was to identify the influencers of primary BS selection in Switzerland. Switzerland. Retrospective analysis of all hospitalizations in Switzerland January 1, 2011 through December 31, 2017 with anonymized data provided by the Swiss Federal Statistical Office. BS procedures were identified based on ICD-10 and national surgical codes. Statistical analyses were performed with R. During the study period 27,375 BS were performed. The annual BS caseload doubled over time, whereas inpatient complications decreased (∼-33%). RYGB was the prevailing procedure, although its annual proportion decreased from 80% to 70% over 7 years. Meanwhile, use of SG increased from 14% to 23%. Primary RYGB and SG had similar rates of inpatient mortality (∼.05%) and morbidity (8.0 versus 7.4%, P =.148), with the exception of higher ileus rates following RYGB (.7 versus .1%, P < .001). Patient-related factors favoring the indication of SG were male sex, extremes of age, and metabolic co-morbidities , while gastroesophageal reflux disease and private insurance-favored RYGB. Strikingly, differences between geographic regions outweighed patient-related factors in procedure selection: inhabitants of German- and Italian-speaking areas had higher likelihood (OR 4.6; 3.9, P < .001) to receive SG than those in French-speaking areas. Geographic differences in primary BS procedure selection indicate a lack of objective rationales. Long-term risk-benefit and cost-effectiveness analyses are needed to assist evidence-based decision making.
