Transferability of economic evaluations across jurisdictions: ISPOR Good Research Practices Task Force report

Joint consensus on reducing the burden of invasive meningococcal disease in the Asia-Pacific region

Invasive meningococcal disease (IMD) imposes a heavy burden of mortality and life-long sequelae on infected individuals and has devastating impacts on their family members. International data show that meningococcal vaccination programs have reduced IMD incidence and changed the serogroup distribution of the disease. Furthermore, newer data show that although the public health measures in response to the coronavirus disease 2019 (COVID-19) pandemic temporarily reduced the incidence of IMD, there has been a resurgence in the years since. In the Asia-Pacific (APAC) region, many countries do not include meningococcal vaccines in their routine vaccination programs, and approaches to IMD surveillance are inconsistent. This review summarizes recent data and consensus statements from a group of experts from selected APAC countries on the burden of IMD in the region, evidence for vaccination, and how barriers to IMD vaccination may be addressed.

The cost-effectiveness of treatment for high-risk, early-stage, triple-negative breast cancer in Egypt: an analysis of neoadjuvant pembrolizumab plus chemotherapy followed by adjuvant single-agent pembrolizumab

OBJECTIVE

The cost-effectiveness of neoadjuvant pembrolizumab + chemotherapy followed by adjuvant pembrolizumab compared to neoadjuvant chemotherapy plus placebo followed by adjuvant placebo was assessed in high-risk, early-stage, triple-negative breast cancer patients from an Egyptian societal perspective over a lifetime horizon.

METHODS

A 4-state Markov cohort model was developed to compare the cost-effectiveness of pembrolizumab + chemotherapy/pembrolizumab vs chemotherapy alone for the treatment of high-risk, early-stage, triple-negative breast cancer. The model simulated the clinical course of high-risk, early-stage, triple-negative breast cancer across four health states: event-free survival, locoregional recurrence, distant metastasis, and death. Clinical inputs for the simulation were derived from modeling of efficacy and safety data collected in the KEYNOTE-522 trial. Direct medical costs and indirect costs were reported in 2022 Egyptian pounds (EGP) and converted to US dollars ($). Probabilistic and deterministic sensitivity analyses were conducted to assess the robustness of model results.

RESULTS

Compared with chemotherapy alone, pembrolizumab + chemotherapy/pembrolizumab led to expected gains of 2.92 life years and 2.25 quality-adjusted life years, respectively, while increasing overall treatment costs by EGP 491,695 ($102,436). Incremental costs per year gained were EGP 218,285 ($45,476) per quality-adjusted life year and EGP 168,223 ($35,046) per life year, both of which were lower than the 2022 Egyptian cost-effectiveness threshold of EGP 398,439 ($83,008). The findings of sensitivity analyses indicated that the model was robust across a range of inputs and assumptions.

CONCLUSIONS

In Egypt, pembrolizumab + chemotherapy/pembrolizumab is a cost-effective treatment for high-risk, early-stage, triple-negative breast cancer when considering health-related quality-of-life and years of life gained.

Cost-Effectiveness of Ultrasound Renal Denervation for Resistant Hypertension in Belgium, France and The Netherlands

BACKGROUND

Endovascular ultrasound renal denervation (uRDN) with the Paradise System has emerged as an adjunctive treatment option for the management of uncontrolled resistant hypertension (rHTN). This study assesses the cost-effectiveness of uRDN for rHTN across three European countries-Belgium, France and the Netherlands.

METHODS

On the basis of a previously developed state-transition Markov model, we projected costs, life years (LYs) and quality adjusted life years (QALYs) with the addition of uRDN to standard of care (SoC) compared with SoC alone over patient lifetime. Analyses were based on the RADIANCE-HTN TRIO trial, which demonstrated a mean reduction in office systolic blood pressure from a baseline of 8.5 mmHg at 2 months post-uRDN among patients with rHTN. Mortality and costs data were separately sourced and applied for each country independently. Country-specific discount rates were applied to both cost and outcomes. One-way and probabilistic sensitivity analyses were conducted to assess the uncertainty surrounding the model inputs and sensitivity of the model results to changes in parameter inputs. Results were reported as incremental cost-effectiveness ratios (ICERs).

RESULTS

The base-case analyses of the models for all three countries show uRDN plus SoC results in improvement in both LYs and QALYs per patient and higher costs compared with SoC alone. The mean ICERs for each country model fall well below the respective country-specific willingness-to-pay thresholds (WTPs)-Belgium: WTP €40,000 and ICER €4426/QALY gained; France: WTP €50,000 and ICER €6261/QALY gained; and the Netherlands: WTP €20,000 and ICER €1654/QALY gained. Results were robust across scenarios and sensitivity analyses.

CONCLUSIONS

The addition of endovascular uRDN offers clinicians and payers a cost-effective adjunctive treatment approach alongside hypertensive medication for the management of rHTN in the healthcare systems of Belgium, France and the Netherlands.

Decision-Analytical Modelling of Medicines in the Middle East: A Systematic Review of Economic Evaluation Studies

BACKGROUND

Economic evaluations through decision-analytical models have played a limited role in shaping healthcare resource optimisation and reimbursement decisions in the Middle East.

OBJECTIVE

This review aims to systematically examine economic evaluation studies focusing on decision-analytical models of medicines in the Middle East, defining methodological characteristics and appraising the quality of the identified models.

METHODS

A systematic review approach was employed to identify published decision-analytical models of medicines in the Middle East. Six databases were searched (MEDLINE, EMBASE, Econlit, Web of Science, Global Health Cost-Effectiveness Analysis Registry and the Global Index Medicus) from 1998 to July 2024. Studies meeting the inclusion criteria-full economic evaluations of medicines using decision-analytical models in the Middle East-were considered. Data were extracted and tabulated to include study characteristics and methodological specifications, and data were narratively analysed. The Philips checklist was used to assess the quality of studies.

RESULTS

Sixty-three decision-analytical modelling studies of medicines were identified and reviewed, from eight Middle Eastern countries, with the majority (90%) conducted in Iran, Saudi Arabia, Qatar and Egypt. The cost-effectiveness of medications for non-communicable diseases was explored in 77% of the models. Gross domestic product-based cost-effectiveness thresholds were commonly used, and international sources provided data on intervention effectiveness and health outcomes, while national sources were mainly used for the costs of resource use. Most models incorporated an assessment of parameter uncertainty, whereas other types of uncertainty were not explored. Studies from high-income countries were generally of higher quality than those from middle-income countries.

CONCLUSIONS

The number of published decision-analytical models in the Middle East was low, considering the available medicinal products and disease burden. Key elements related to the quality of decision-analytical models, including analysis of the model structure, appropriateness of model inputs and uncertainty assessment, were not consistently fulfilled. Recommendations are provided to enhance the quality of future economic evaluation studies. This includes strengthening the existing health economics capacities, establishing country-specific health technology assessment systems (where possible), and initiating collaborations to generate national cost and outcome data.

Value-Based Pricing for Drugs With Uncertain Clinical Benefits

Policymakers can use cost-effectiveness analysis to set value-based prices (VBP) for new pharmaceuticals. However, the uncertainty of investigational drug benefits complicates this pricing strategy. Such complexity stems from decision-makers' risk aversion and the potential change in the estimated value with emerging evidence. The recent surge in drugs approved via the Accelerated Approval (AA) pathway in the U.S. has made incorporating uncertainty into VBP crucial. We propose to estimate risk-adjusted VBP (rVBP) for drugs with uncertain benefits via integrating value of information and expected utility theory. Our approach involves two assessment points: an initial assessment with existing evidence; and a reassessment with new evidence that reduces uncertainty. This approach enables decision-makers to set rVBP in the initial assessment such that the expected utility, from the exisiting evidence, aligns with the benchmark uncertainty. We evaluate two benchmarks: one with no uncertainty, and one with a decision-maker's acceptable uncertainty level. We show in a case study of a hypothetical AA drug that rVBP may be lower than traditional VBP, especially under high risk aversion or low acceptable uncertainty. Our methodology adjusts VBP to account for uncertainty, supporting decision-makers in balancing timely market access with the risks associated with uncertainty in the benefits of new pharmaceuticals.

The Lebanese health economic evaluation guideline

BACKGROUND

Economic evaluation guidelines (EEGs) serve as a valuable tool to assist appraisers in making consistent and transparent recommendations, standardize EE studies, enhance their quality, and minimize methodological uncertainties. As other LMICs, Lebanon aims for UHC where EEG is a necessity. This paper aims to report on the Lebanese health EEG (LEEG) and its reference case, including the intermediate results leading to the final decisions.‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬.

RESEARCH DESIGN AND METHODS

The LEEG followed a structured, systematic, and transparent process: (1) identifying the rationale and the guideline scope; (2) establishing the Guideline Development Group; (3) searching the evidence; (4) planning the development process; (5) selecting the panel for the deliberative process; (6) surveying Lebanese stakeholders; (7) deliberating on the results; (8) drafting the guideline; and (9) consulting with international experts.

RESULTS

The LEEG includes three general characteristics, 19 key features, a reference case, and an action plan.

CONCLUSIONS

The LEEG is the first national EEG for health interventions. It will help decision-makers, researchers, and healthcare providers improve the quality and assessment of EE in Lebanon to identify the most cost-effective health interventions. Implementing LEEG is crucial to promoting an equitable, efficient, and high-quality health system with a more consistent decision-making process.

Cost-effectiveness of treatment sequences for BRAF-mutant advanced melanoma in the Netherlands using a health economic model

BACKGROUND

This study aims to evaluate the cost-effectiveness of treatment sequences for patients with advanced melanoma with a BRAF mutation in the Netherlands from a societal perspective.

METHODS

A semi-Markov model with a life-time horizon has been used to evaluate cost-effectiveness of 21 treatment sequences. Real-world data from the Dutch Melanoma Treatment Registry (DMTR) were used to estimate time to progression, next treatment and death. Utilities by health state as well as hospital costs, health care costs outside the hospital, patient and family costs and productivity costs were also derived from the DMTR. Drug costs were estimated based on the recommended dose and duration of treatment. Incremental cost-effectiveness ratios (ICERs) were presented as incremental costs per QALY gained.

RESULTS

Health benefits of treatment sequences consisting of targeted therapies and immunotherapies vary between 2.3 and 5.8 QALYs gained per patient when compared to chemotherapy. The increase in costs varies between €112,000 and €383,000. The efficiency frontier consists of nivolumab in the first line followed by ipilimumab in the second line (ICERs of €42,000/QALY and €44,000/QALY), nivolumab in the first line followed by encorafenib plus binimetinib in the second line (ICERs of €71,000/QALY and €68,000/QALY) and nivolumab plus ipilimumab in the first line followed by encorafenib plus binimetinib in the second line (ICERs of €74,000/QALY and €76,000/QALY). The first treatment given within a sequence as well as assumptions regarding treatment duration have a substantial impact on cost-effectiveness outcomes.

CONCLUSION

The ICERs can be considered cost-effective at different cost-effectiveness thresholds.

Dapagliflozin for the treatment of heart failure with reduced ejection fraction in Brazil: a cost-effectiveness analysis

Background

Heart failure, a complex clinical syndrome with high morbidity and mortality, has become a significant burden on public health. Recently, a new class of antidiabetic agents-the sodium-glucose cotransporter 2 (SGLT2) inhibitors-was associated with a significant reduction on mortality and hospitalization in HF with reduced ejection fraction (HFrEF) when added to standard pharmacological treatment. Considering the lack of data on its cost-effectiveness, the present study aims to estimate the incremental cost-effectiveness ratio of add-on dapagliflozin treatment for HFrEF from the Brazilian public healthcare system perspective.

Methods

We built a Markov model to estimate the clinical outcomes and costs of 1,000 hypothetical subjects with established HFrEF in a lifetime horizon. The model inputs were based on the Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure (DAPA-HF) trial and local data. The main outcome was the incremental cost-effectiveness ratio (ICER) per quality-adjusted life year (QALY) gained. Deterministic and probabilistic sensitivity analyses, as well as scenario analyses, were performed.

Findings

The addition of dapagliflozin to standard care treatment in 1,000 HFrEF patients yielded an expected value of 366.99 additional QALYs at an incremental cost of US$ 1,517,878.49, resulting in an ICER of US$ 4,136.08 per QALY gained, being a cost-effective strategy considering the Brazilian official cost-effectiveness threshold (US$ 8,000/QALY). In probabilistic sensitivity analyses, 96.60% of the simulations were also cost-effective. In the scenario analyses, results were similar for individuals with and without diabetes.

Interpretation

Dapagliflozin is likely to be cost-effective when added to standard HFrEF therapy in Brazil.

Funding

This study was supported by the National Institute of Science and Technology for Health Technology Assessment (Instituto de Avaliação de Tecnologias em Saúde-IATS).

The international trial of nasal oxygen therapy after cardiac surgery (NOTACS) in patients at high risk of postoperative pulmonary complications: Economic evaluation protocol and analysis plan

INTRODUCTION

High-Flow Nasal Therapy (HFNT) is an innovative non-invasive form of respiratory support. Compared to standard oxygen therapy (SOT), there is an equipoise regarding the effect of HFNT on patient-centred outcomes among those at high risk of developing postoperative pulmonary complications after undergoing cardiac surgery. The NOTACS trial aims to determine the clinical and cost-effectiveness of HFNT compared to SOT within 90 days of surgery in the United Kingdom, Australia, and New Zealand. This protocol describes the methods and analyses planned for economic evaluation embedded within the ongoing NOTACS trial.

METHODS AND ANALYSIS

The economic evaluation will identify, measure and value resources and health outcomes in both trial arms and compare changes in costs with 'days alive and at home' and EQ-5D-5L quality adjusted life years (QALYs) from the perspective most relevant to the decision-making country. Results from pooling data across the trial will use health and social care sector perspective. All patient-specific data including hospital/community care and health outcomes will be collected prospectively. Unit costs will be sourced from national, published or local data. Missing data will be assessed, with values replaced depending on assumed mechanism of missingness, and impact of replacement on cost-effectiveness assessed. Costs and outcomes by trial arm will be presented as components and totals per patient using a range of descriptive statistics. Regression models for costs and effects will account for patient characteristics, quality of life and health service utilization at baseline. Uncertainty in parameters, sampling and heterogeneity will be addressed through deterministic, probabilistic and subgroup analyses to assess the impact of varying methods and assumptions for costs, outcomes and approaches used in base-case analysis. Results will be interpreted using recommended national cost-effectiveness thresholds.

REGISTRATION DETAILS

The study is registered with ISRCTN (ISRCTN14092678) on 13/05/2020. ISRCTN is a primary registry of the WHO ICTRP network and includes all items from the WHO Trial Registration data set.

Validation of the PECUNIA reference unit costs templates in Spain: a useful tool for multi-national economic evaluations of health technologies

BACKGROUND

The PECUNIA Project was funded by the H2020 programme in which 10 partners from six countries participated. The aim was to develop standardized, harmonized and validated methods and tools to calculate costs in different sectors (such as health and social care, education among others), with the purpose of facilitating comparability of economic evaluations of health technologies across European countries. In this paper we report the first validation of the developed reference unit cost templates in Spain.

METHODS

The evaluation of the PECUNIA Reference Unit Cost (RUC) Templates involved usability, transferability and feasibility assessment. Applicability tests were performed to estimate the cost of a selection of 15 resource items by means of the RUC templates in Spain and in four Spanish regions. External validation involved comparison with existing unit costs.

RESULTS

It was possible to estimate the cost of five services (dental care and general practitioner in the Canary Islands, general practitioner in Spain [tariffs], health-related day care centre and education services provided in a special education school in the Basque Country), car vandalism as an example of potential health-related consequences, and informal care in Spain. The templates were feasible although data completeness depended on the type of data needed to estimate the costs. The templates are transferable across countries although comparability depends on the services available in each jurisdiction.

CONCLUSIONS

The PECUNIA RUC Templates are free and feasible tools to estimate comparable reference unit costs across countries. Although more validation exercises are needed, they seem useful tools to perform robust multi-national economic evaluations and increase the transferability of cost-effectiveness studies of health technologies in Europe. However, they cannot compensate for the lack of data across jurisdictions.

Cost-effectiveness of falls prevention strategies for older adults: protocol for a living systematic review

INTRODUCTION

One-third of adults aged 65+ fall annually. Injuries from falls can be devastating for individuals and account for 1.5% of annual healthcare spending. With the growing ageing population, falls place increased strain on scarce health resources. Prevention strategies that target individuals at high risk for falls demonstrate the best value for money; however, limited efficiency (ie, cost-effectiveness) information for fall prevention interventions hinders the implementation of effective falls prevention programmes. Living systematic reviews provide a timely up-to-date evidence-based resource to inform clinical guidelines and health policy decisions. This protocol details the methodology for a living systematic review of the efficiency (ie, cost-effectiveness) of fall prevention interventions for older adults in three settings: community-dwelling, aged care and hospitals.

METHODS AND ANALYSIS

This protocol used the reporting guidelines from the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocol. Peer-reviewed economic evaluations of controlled clinical trials or health state models will be included. Reports will be obtained through monthly systematic searches of CENTRAL (Ovid), CINAHL (EBSCO), Embase (Ovid), MEDLINE (Ovid), SCOPUS (Elsevier) and Web of Science (Clarivate) alongside snowballing and handsearching EconLit and the Tufts Cost Effectivness Analysis Registry. Screening, data extraction, quality assessment and risk of bias will be assessed by multiple reviewers. The primary outcomes will be the incremental cost-effectiveness (ie, incremental cost per fall prevented), incremental cost-utility (ie, incremental cost per quality-adjusted life year gained) or cost-benefit ratio. Additional outcomes will include falls and cost-related measures. All economic outcomes will be reported in a common year and currency. Results will be reported as a narrative synthesis; meta-analysis will be considered based on data quality, suitability and availability.

ETHICS AND DISSEMINATION

Ethical approval is not required as primary human data will not be collected. Results will be disseminated through peer-reviewed publications and a dedicated website.

Use of transportability methods for real-world evidence generation: a review of current applications

Aim: To evaluate how transportability methods are currently used for real-world evidence (RWE) generation to inform good practices and support adoption and acceptance of these methods in the RWE context. Methods: We conducted a targeted literature review to identify studies that transported an effect estimate of the clinical effectiveness or safety of a biomedical exposure to a target real-world population. Records were identified from PubMed-indexed articles published any time before 25 July 2023 (inclusive). Two reviewers screened abstracts/titles and reviewed the full text of candidate studies to identify the final set of articles. Data on the therapeutic area, exposure(s), outcome(s), original and target populations and details of the transportability analysis (e.g., analytic method used, estimate transported, stated assumptions) were abstracted from each article. Results: Of 458 unique records identified, six were retained in the final review. Articles were published during 2021-2023, focused on the US/Canada context, and covered a range of therapeutic areas. Four studies transported an RCT effect estimate, while two transported effect estimates derived from real-world data. Almost all articles used weighting methods to transport estimates. Two studies discussed all transportability assumptions, and one evaluated the likelihood of meeting all assumptions and the impact of potential violations. Conclusion: The use of transportability methods for RWE generation is an emerging and promising area of research to address evidence gaps in settings with limited data and infrastructure. More transparent and rigorous reporting of methods, assumptions and limitations may increase the use and acceptability of transportability for producing robust evidence on treatment effectiveness and safety.

National Recommendations for Pharmacoeconomic Evaluations Reporting for Reimbursement and Procurement of New Pharmaceutical Applications in Egypt

Introduction

To improve resource allocation within our healthcare system, the Egyptian Authority for Unified Procurement, Medical Supply and the Management of Medical Technology (UPA) and Universal Health Insurance Authority (UHIA) established a joint economic evaluation process to support UHIA reimbursement decisions and UPA procurement decisions. The main objective of this study is to describe the developed national pharmacoeconomic guidelines in Egypt, especially for reimbursement and procurement for new pharmaceuticals.

Methods

A focus group was formed as a national initiative activity by governmental authorities in Egypt. The aim of this focus group was to develop national pharmacoeconomic guidelines for the evaluation of innovative and high-budget pharmaceutical products. This group consisted of various stakeholders with experience in health economics, outcomes research, public health, and pharmacy practice. To develop our national pharmacoeconomic guidelines, three steps were taken. First, the focus group reviewed the European Network for Health Technology Assessment (EUnetHTA) methods for health economic evaluations for new pharmaceuticals as well as the Canadian Agency for Drugs and Technologies in Health (CADTH) guidelines and the Academy of Managed Care Pharmacy (AMCP) Format for Formulary Submissions. Second, the focus group used the EUnetHTA guideline as a reference and adapted it to our local context. The focus group added the value assessment component, using the CADTH and AMCP guidelines. Third, the focus group collected input and feedback from key stakeholders through a focus group by using the quasi-Delphi panel approach.

Results

The results of the focus group are a main structure of national pharmacoeconomic guidelines for the evaluation of innovative and high-budget pharmaceutical products, consisting of seven main topics.

Conclusion

Economic evaluation is a core element of Health Technology Assessment, (HTA); therefore, the UHIA and UPA were encouraged to produce unified joint pharmacoeconomic guidelines for innovative products as an initial step in their commitment to implement the use of HTA in decision-making. This standardization of guidelines not only ensures transparency but also guarantees an accurate and transparent process to support evidence-based decision-making. These guidelines are expected to help decision-makers improve their process and attain better health outcomes for Egyptian patients.

Artificial-Intelligence Cloud-Based Platform to Support Shared Decision-Making in the Locoregional Treatment of Breast Cancer: Protocol for a Multidimensional Evaluation Embedded in the CINDERELLA Clinical Trial

BACKGROUND

Shared decision-making (SDM) plays a crucial role in breast cancer care by empowering patients and reducing decision regret. Patient decision aids (PtDAs) are valuable tools for facilitating SDM, now available in digital and artificial intelligence (AI)-powered formats to offer increasingly personalized contents. The ongoing CINDERELLA clinical trial (ClinicalTrials.gov: NCT05196269) evaluates an innovative AI cloud-based approach using a web platform and a mobile application (CINDERELLA APProach) versus the conventional approach to support SDM in breast cancer patients undergoing locoregional treatment. This protocol outlines a trial-based multidimensional evaluation, encompassing economic, financial, implementability, and environmental considerations associated with the CINDERELLA APProach.

METHODS

A within-trial cost-consequence and cost-utility analysis from a societal perspective will be performed using patient-level data on outcomes and resource use. The latter will be valued in monetary terms using country-specific unit costs or patient valuations. A budget impact analysis will be performed over 1 and 5 years from the budget holder perspectives. The CINDERELLA APProach implementability will be assessed through an evaluation of its usability, acceptability, organizational impact, and overall feasibility. The environmental impact will be quantitatively assessed across several dimensions, such as quantity, appropriateness, and emissions, supplemented by qualitative insights. Overall, data for the evaluation will be gathered from patient questionnaires, interviews with patients and managers, focus groups with healthcare professionals, and app electronic data.

DISCUSSION

A thorough understanding of the broad consequences of the CINDERELLA APProach may foster its successful translation into real-world settings, hopefully benefiting breast cancer patients and clinical practice.

Systematic Review of Tools and Approaches for Evaluating the Transferability of Health Technology Assessments Across Different Jurisdictions

BACKGROUND

This study aims to review tools that have been developed for the transferability of health technology assessment (HTA) information to different countries. HTA is increasingly being used as a tool in health policy decision-making, but its complexity and lack of local expertise have limited its usage in many countries. The World Health Organization (WHO) has taken measures to encourage countries to conduct and use HTA, including through resolutions from the Eastern Mediterranean (EM) Regional Committee in 2019. However, due to limitations in national technical capacities, there is a need to adapt HTA information from other settings to fit the specific context of each country. Therefore, this study aims to systematically review the tools that have been developed for HTA transferability and assess their strengths and limitations.

METHODS

The systematic review included studies that introduced tools, methods, and frameworks for transferability of HTA information across jurisdictions. Databases such as MEDLINE, EMBASE, Cochrane Library, Epistemonikos, Web of Science, health economic database, Scopus, and Google Scholar were searched, along with relevant bibliographies. The data was extracted and synthesized using both tabulation and narrative approaches. The evaluation of the tools involved assessing various criteria, such as user-friendliness, efficiency in screening, and considerations regarding transferability factors.

RESULTS

A total of 10 375 documents were evaluated, resulting in 17 studies that met the inclusion criteria. These 17 studies consisted of 13 newly developed tools/methods that were appraised. The majority of the models were checklists, with only a few deemed suitable for full HTA. Three models have been validated through published studies, but there is no evidence of utilization in the countries of the EM region.

CONCLUSION

While the existing tools provide valuable resources for evaluating transferability, there remains a need for a more comprehensive tool to support decision-makers in low-resource settings considering country context and capacity.

Potential Cost Savings with 60-day Peripheral Nerve Stimulation Treatment in Chronic Axial Low Back Pain

INTRODUCTION

Chronic axial low back pain (CLBP) that is not responsive to medication management or physical therapy often requires significant clinical intervention. Several interventional pain management options exist, including a 60-day peripheral nerve stimulation (PNS) treatment. This economic evaluation investigated the potential for projected cost savings associated with prioritizing 60-day PNS treatment relative to a 'standard of care' (SOC) approach (where patients do not have access to 60-day PNS).

METHODS

A decision tree (supervised machine learning) model tracked treatment progression across two hypothetical cohorts of US patients with CLBP in whom non-interventional options were ineffective (Cohort A: treatment starting with 60-day PNS followed by any additional interventional and surgical treatments versus Cohort B: standard of care interventional and surgical treatments without access to 60-day PNS). Treatment efficacy estimates were based on published success rates. Conditional on treatment failure, up to two additional interventions were considered within the 12-month time frame in both cohorts. SOC treatment options included epidural injection, radiofrequency ablation (RFA), basivertebral nerve ablation (BVNA), PNS permanent implant (PNS-PI), spinal cord stimulator (SCS) trial/implant, and spinal fusion surgery. Treatment choice probabilities in both cohort algorithms were based on clinician interviews. Costs were based on national Medicare reimbursement levels in the ambulatory surgery center (ASC) setting. Savings reflected the difference in projected costs between cohorts. A Monte Carlo simulation and sensitivity analyses were conducted to generate confidence intervals and identify important inputs.

RESULTS

The treatment algorithm which prioritized initial 60-day PNS treatment was projected to save $8056 (95% CI $6112-$9981) per patient during the first year of interventional treatment relative to the SOC approach.

CONCLUSIONS

Use of the 60-day PNS treatment as an initial interventional treatment in patients with CLBP may result in significant savings for Medicare. Projected savings may be even larger for commercial payers covering non-Medicare patients.

Automated Drugs Dispensing Systems in Hospitals: a Health Technology Assessment (HTA) Study Across Six European Countries

Background

Automated Drug Dispensing (ADD) systems are considered to be strategic hospital assets used to reduce errors and enhance economic and organizational sustainability. With regards to efficacy and safety, the literature evidence demonstrates the incremental benefits of centralised or decentralised systems compared to manual dispensing. Analyses about organisational and economic sustainability are still lacking and the present study aims to perform a Health Technology Assessment (HTA), producing multidimensional evidence on the use of ADD systems within hospitals.

Methods

In 2023, a comprehensive HTA draws insights from healthcare professionals across six European nations: Italy, France, Germany, the Netherlands, the United Kingdom, and Belgium. This appraisal juxtaposed four drug dispensing scenarios: manual methods, centralized ADD systems, decentralized ADD systems, and integrated solutions employing cutting-edge technologies in both central pharmacies and wards. The study deployed an Activity-Based Costing approach that was combined with a cost-effectiveness and Budget Impact Analysis to evaluate economic impacts. Qualitative questionnaires were implemented to assess ethical, legal, organizational, safety, and efficacy aspects.

Results

From a multidimensional perspective, healthcare professionals acknowledged ADD manifold advantages of ADD systems. From an organizational perspective and within a 12-month timeframe, transitioning to automation may face initial challenges that are attributed to potential resistance from professionals and significant investments. However, 36 months past its adoption, automation's superiority over manual methods was recognized. Economically, savings burgeoned from +17.9% in UK to +26.6% in Belgian hospitals that adopted integrated systems in comparison to traditional manual approaches.

Conclusion

Compared to traditional methods, implementing ADD systems could improve the logistic management of drug in the hospital setting, thereby enhancing safety and efficacy, streamlining the healthcare professionals' workflow, and bolstering financial stability.

Equity in national healthcare economic evaluation guidelines: Essential or extraneous?

BACKGROUND

The focus on health maximisation in a healthcare economic evaluation (HEE) - that is health gains are of equal value regardless of the recipient- has significant implications as health systems attempt to address persistent and growing health inequities. This study aimed to systematically compare and contrast the equity principles of different health technology assessment (HTA) agencies and how equity is addressed in HEE guidelines.

METHODS

HTA agencies were identified through the ISPOR, GEAR, iDSI, HTAi, INAHTA, HTAsiaLink, and RedETSA websites in June 2021 and updated in August 2023. Agencies websites were then searched to retrieve HEE guidelines. The guidelines were grouped into two categories: well-established and newly-developed agency guidelines, based on whether or not they published their first guidelines before 2009. Data extracted summarised the methodological details in the reference cases, including specifics on how equity featured and in what role. In those agencies where equity did not feature explicitly in the HEE guidelines, an additional search of the agency website was undertaken to understand if equity featured in those agencies' decision-making frameworks.

RESULTS

The study included 46 guidelines from 51 countries. Only 30% of the guidelines were explicit about the equity assumptions. Health equity (using a broad definition) was mentioned in 29 guidelines and 14 included a specific definition while only seven recommended specific methods to incorporate inequalities. Addressing equity concerns was usually suggested as an additional analyses rather than a key part of the assessment. It was unclear how equity was incorporated into decision-making processes. In addition, equity was mentioned in other guidance - such as decision-making frameworks - provided by five agencies that did not mention it in the HEE guidelines, and 7 of 14 topic selection criteria that were identified.

CONCLUSION

Equity is given less attention than efficiency in HEE guidelines. This indicates that HTA agencies while subscribing to an extra-welfarist approach have a narrow evaluative space - focusing on maximising health and not considering the opportunity cost of the equity constraint. The omission of equity and the lack of systematic approaches in guidelines poses a threat to the international endeavours to reduce inequities. It is timely for HTA agencies to reconsider their positions on equity explicitly.

How Do the Institute for Clinical and Economic Review's Assessments of Comparative Effectiveness Compare With the German Federal Joint Committee's Assessments of Added Benefit? A Qualitative Study

OBJECTIVES

We compared the Institute for Clinical and Economic Review's (ICER) ratings of comparative clinical effectiveness with the German Federal Joint Committee's (G-BA) added benefit ratings, and explored what factors may explain the disagreement between the 2 organizations.

METHODS

We included drugs if they were assessed by ICER under its 2020 to 2023 Value Assessment Framework and had a corresponding assessment by G-BA as of January 2024 for the same indication, patient population, and comparator drug. To compare assessments, we modified ICER's proposed crosswalk between G-BA and ICER benefit ratings to account for G-BA's certainty ratings. We also determined whether each pair was based on similar evidence. Assessment pairs exhibiting disagreement based on the modified crosswalk despite a similar evidence base were qualitatively analyzed to identify reasons for disagreement.

RESULTS

Out of 15 drug assessment pairs matched on indication, patient subgroup, and comparator, none showed agreement in their assessments when based on similar evidence. Disagreement was attributed to differences in evidence evaluation, including evaluations of safety, generalizability, and study design, as well as G-BA's rejection of the available evidence in 4 cases as unsuitable.

CONCLUSIONS

The findings demonstrate that even under conditions where populations and comparators are identical and the evidence base is consistent, different assessors may arrive at divergent conclusions about comparative effectiveness, thus underscoring the presence of value judgments within assessments of clinical effectiveness. To support initiatives that seek to facilitate the exchange of value assessments between countries, these value judgments should always be transparently presented and justified in assessment summaries.

Cost-Effectiveness Analysis of Pharmacological Treatment for Adult Kidney Transplant Recipients in Colombia

OBJECTIVES

To evaluate cost-effective pharmacological treatment in adult kidney transplant recipients from the perspective of the Colombian health system.

METHODS

A decision tree model for the induction phase and a Markov model for the maintenance phase were built. A review of the clinical literature was conducted to extract probabilities, and the life-years were used as the outcome. Costs were calculated using the administrative databases. The evaluating treatment schemes are organized by groups of evidence with direct comparisons.

RESULTS

In the induction phase, anti-thymocyte immunoglobulin+ methylprednisolone is dominant, more effective, and less expensive, compared with basiliximab+methylprednisolone. In the maintenance phase, azathioprine (AZA) is dominant in contrast to mycophenolate mofetil (MFM) both with cyclosporine (CIC)+ corticosteroids (CE); CIC is dominant relative to sirolimus (SIR) and tacrolimus (TAC) (both with MFM+CE or AZA+CE), and TAC is dominant compared with SIR (in addition with MFM+CE or mycophenolate sodium [MFS]+CE); MFM is dominant in relation to MFS and everolimus, and SIR is more effective MFM but it does not exceed the threshold (in sum with TAC+CE); MFS and MFM are dominant relative to everolimus, and SIR is more effective than MFM, but it does not exceed the threshold (in addiction with CIC+CE); MFM is dominant in relation to TAC (in sum with SIR+CE), and CIC+AZA+CE is dominant in relation to TAC+MFM+CE.

CONCLUSIONS

The base-case results for all evidence groups are consistent with the different sensitivity analyses.

Cost effectiveness of interventions to prevent the occurrence and the associated economic impacts of child maltreatment: A systematic review

BACKGROUND

Child maltreatment is a pressing public health concern that poses long-lasting health and economic impacts on children and society. While several preventive interventions have demonstrated their effectiveness in reducing the occurrence of child maltreatment and its associated economic impacts, the cost-effectiveness of such interventions remains unclear.

OBJECTIVE

This study aims to provide a comprehensive overview and a narrative synthesis of the available economic evidence on child maltreatment preventive interventions in both high-income and low-middle-income countries.

METHOD

Systematic searches were conducted in MEDLINE, PsycINFO, Embase, CINAHL, Web of Science, and Econlit to identify full economic evaluations and return-on-investment studies on child maltreatment preventive interventions. The methodological quality of eligible studies was assessed using Drummond's 10-point checklist. This review adhered to the PRISMA guidelines, and summarized findings in a narrative synthesis.

RESULTS

Twenty-six studies met the inclusion criteria. Of these, eight evaluated home visiting, four evaluated early childhood education (ECE), four assessed multi-component (MC), and three examined group-based parent education (GPE) interventions. The remaining studies assessed interventions to prevent abusive head trauma (AHT; n = 2), child sexual abuse (n = 2), physical abuse at school (n = 1), as well as individualized intensive parenting (IIP; n = 2), and counseling (n = 1) interventions. Two studies were conducted in low-middle-income countries, while the others were all in high-income countries.

CONCLUSIONS

The included studies generally exhibited high methodological quality. Only AHT, ECE, IIP, and MC interventions demonstrated promising cost-effectiveness credentials in preventing child maltreatment. More economic evaluations are needed for interventions with mixed findings (e.g. GPE) and in low-middle-income countries.

Economic evaluations of alcohol pharmacotherapy: Systematic review of economic evaluations of pharmacotherapy for the treatment of alcohol use disorder

OBJECTIVE

Alcohol use disorders confer a significant burden of disease and economic cost worldwide. However, the utilisation of pharmacotherapies to manage alcohol use disorder is poor. We aimed to conduct a systematic review of economic evaluation studies of alcohol use disorder pharmacotherapies.

METHODS

A search was conducted in Embase, Medline, CINAHL, PsychINFO and EconLit (August 2019, updated September 2022). Full economic evaluations using pharmacotherapy to treat alcohol use disorders were included. Included studies were stratified by medication and summarised descriptively. The Consensus on Health Economic Criteria list was used to assess the methodological quality.

RESULTS

A total of 1139 studies were retrieved, of which 15 met the inclusion criteria. All studies were conducted in high-income countries. Four studies analysed nalmefene, four studies assessed acamprosate, three for naltrexone and four for stand-alone and/or combinations of naltrexone and acamprosate. There were 21 interventions synthesised from 15 studies as some studies evaluated multiple interventions and comparators. More than half of the included studies (73%) reported pharmacotherapy as dominant (less costly and more effective than comparators). From healthcare payer perspectives, five studies found that pharmacotherapy added to psychosocial support was dominant or cost-effective, accruing additional benefits at a higher cost but under accepted willingness to pay thresholds. Three analyses from a societal perspective found pharmacotherapy added to psychosocial support was a dominant or cost-effective strategy. Quality scores ranged from 63% to 95%.

CONCLUSION

Pharmacotherapy added to psychosocial support was cost-effective from both healthcare and societal perspectives, emphasising an increased role for pharmacotherapy to reduce the burden of alcohol use disorders.

Research trends in contemporary health economics: a scientometric analysis on collective content of specialty journals

INTRODUCTION

Health economics is a thriving sub-discipline of economics. Applied health economics research is considered essential in the health care sector and is used extensively by public policy makers. For scholars, it is important to understand the history and status of health economics-when it emerged, the rate of research output, trending topics, and its temporal evolution-to ensure clarity and direction when formulating research questions.

METHODS

Nearly 13,000 articles were analysed, which were found in the collective publications of the ten most specialised health economic journals. We explored this literature using patterns of term co-occurrence and document co-citation.

RESULTS

The research output in this field is growing exponentially. Five main research divisions were identified: (i) macroeconomic evaluation, (ii) microeconomic evaluation, (iii) measurement and valuation of outcomes, (iv) monitoring mechanisms (evaluation), and (v) guidance and appraisal. Document co-citation analysis revealed eighteen major research streams and identified variation in the magnitude of activities in each of the streams. A recent emergence of research activities in health economics was seen in the Medicaid Expansion stream. Established research streams that continue to show high levels of activity include Child Health, Health-related Quality of Life (HRQoL) and Cost-effectiveness. Conversely, Patient Preference, Health Care Expenditure and Economic Evaluation are now past their peak of activity in specialised health economic journals. Analysis also identified several streams that emerged in the past but are no longer active.

CONCLUSIONS

Health economics is a growing field, yet there is minimal evidence of creation of new research trends. Over the past 10 years, the average rate of annual increase in internationally collaborated publications is almost double that of domestic collaborations (8.4% vs 4.9%), but most of the top scholarly collaborations remain between six countries only.

Cost-Utility Analysis of Geriatric Assessment and Management in Older Adults With Cancer: Economic Evaluation Within 5C Trial

PURPOSE

Geriatric assessment (GA) is a guideline-recommended approach to optimize cancer management in older adults. We conducted a cost-utility analysis alongside the 5C randomized controlled trial to compare GA and management (GAM) plus usual care (UC) against UC alone in older adults with cancer.

METHODS

The economic evaluation, conducted from societal and health care payer perspectives, used a 12-month time horizon. The Canadian 5C study randomly assigned patients to receive GAM or UC. Quality-adjusted life-years (QALYs) were measured using the EuroQol five dimension-5L questionnaire and health care utilization using cost diaries and chart reviews. We evaluated the incremental net monetary benefit (INMB) for the full sample and preselected subgroups.

RESULTS

A total of 350 patients were included, of whom 173 received GAM and 177 UC. At 12 months, the average QALYs per patient were 0.728 and 0.751 for GAM and UC, respectively (ΔQALY, -0.023 [95% CI, -0.076 to 0.028]). Considering a societal perspective, the total average costs (in 2021 Canadian dollars) per patient were $46,739 and $45,177 for GAM and UC, respectively (ΔCost, $1,563 [95% CI, -$6,583 to $10,403]). At a cost-effectiveness threshold of $50,000/QALY, GAM was not cost-effective compared with UC (INMB, -$2,713 [95% CI, -$11,767 to $5,801]). The INMB was positive ($2,984 [95% CI, -$7,050 to $14,179]; probability of being cost-effective, 72%) for patients treated with curative intent, but remained negative for patients treated with palliative intent (INMB, -$9,909 [95% CI, -$24,436 to $4,153]). Findings were similar considering a health care payer perspective.

CONCLUSION

To our knowledge, this is the first cost-utility analysis of GAM in cancer. GAM was cost-effective for patients with cancer treated with curative but not with palliative intent. The study provides further considerations for future adoption of GAM in practice.

Savings associated with surgical aortic valve replacement with a RESILIA tissue valve based on seven-year COMMENCE trial results

BACKGROUND

Bioprostheses with RESILIA tissue demonstrate a reduction in calcification and improve health outcomes in pre-clinical and clinical studies. Prior economic analyses which relied on 5 years of evidence from the COMMENCE trial demonstrate financial savings for RESILIA tissue valves relative to mechanical valves after surgical aortic valve replacement (SAVR). Given the recent release of 7-year COMMENCE data, this economic evaluation updates the estimate for long-run savings of bioprosthetic valves with RESILIA.

METHODS

Simulation models estimated disease progression across two hypothetical SAVR cohorts (tissue vs. mechanical) of 10,000 patients each in the US. The primary comparison calculated the SAVR-related expenditures associated with each valve type ($US, 2023). Health outcome probabilities were based on the COMMENCE trial though year 7 and projected for an additional 8 years based on prior studies of tissue and mechanical SAVR. Costs for key outcomes (mortality, reoperation, bleeding, thromboembolism, endocarditis) and anticoagulant monitoring were sourced from the literature. Incidence rates of health outcomes associated with mechanical valves relied on relative risks of tissue valve versus mechanical valve patients.

RESULTS

Seven-year savings are $13,415 (95% CI = $10,472-$17,321) per patient when comparing RESILIA versus mechanical SAVR. Projected 15-year savings were $23,001 ($US, 2023; 95% CI = $17,802-$30,421). Most of the 15-year savings are primarily attributed to lower anti-coagulation monitoring costs ($21,073 in ACM savings over 15 years), but lower bleeding cost (savings: $2,294) and thromboembolism-related expenditures (savings: $852) also contribute. Reoperation and endocarditis expenditures were slightly larger in the RESILIA cohort. If reoperation relative risk reverts from 1.1 to 2.2 (the level in legacy tissue valves) after year 7, savings are $18,064. RESILIA SAVR also reduce costs relative to legacy tissue valves.

CONCLUSION

Patients receiving RESILIA tissue valves are projected to have lower SAVR-related health expenditures relative to mechanical and legacy tissue valves.

Short- and long-term cost-effectiveness of abrocitinib versus dupilumab in adults with moderate-to-severe atopic dermatitis in China

BACKGROUND

Biologics and JAK inhibitors were the most effective innovative systemic treatments for moderate-to-severe atopic dermatitis (AD). However, their cost-effectiveness in China remains unclear. This study aims to compare both the short- and long-term cost-effectiveness of abrocitinib and dupilumab in adults with moderate-to-severe AD from the perspective of the Chinese healthcare system.

METHODS

A hybrid decision tree and Markov model were developed to simulate the costs and health outcomes of interventions on both short-term and long-term horizons. Short- and long-term horizons were employed to reflect the 26-week induction treatment and model the extended 10-year maintenance treatment period, respectively. The cost-effectiveness of strategies was measured by incremental cost-effectiveness ratios (ICERs), which were then compared with the willingness-to-pay threshold (WTP) that was equivalent to the gross domestic product (GDP) per capita of China in 2023 ($12,681 [€11,679.26]). One-way and probabilistic sensitivity analyses were conducted to validate the robustness of the model.

RESULTS

Over the short-term horizon, the QALYs (quality-adjusted life years) gained were 0.43 for the abrocitinib group and 0.42 for the dupilumab group, with the costs being $2,716.01 (€2,501.46) and $3,940.33 (€3,629.06), respectively. Over the long-time horizon, abrocitinib therapy yields higher QALYs (6.60 versus 6.53) and incurs a lower cost ($22,765.15 [€20,966.81] versus $30,683.38 [€28,259.54]) compared to dupilumab. The probability of abrocitinib being cost-effective was nearly 100% under the current WTP. Both short- and long-term results showed that abrocitinib was more effective and less costly than dupilumab, making abrocitinib the dominant option.

CONCLUSIONS

Abrocitinib was dominant compared to dupilumab both over the short- and long-term horizon for moderate-to-severe AD in China. Future research incorporating real-world evidence and long-term efficacy outcomes could further refine these economic evaluations.

Is Using Sodium-Glucose Cotransporter-2 Inhibitors to Treat Adults with Chronic Heart Failure Cost-Effective? A Systematic Review of Cost-Effectiveness Studies

OBJECTIVE

This systematic review aimed to summarise the outcomes of economic evaluations that evaluated sodium-glucose cotransporter-2 inhibitors (SGLT2i) in combination with standard of care compared to standard of care alone for patients with chronic heart failure.

METHODS

This systematic review searched MEDLINE, CINAHL+, Econlit, Scopus, the Cochrane Library, the National Health Service Economic Evaluation Database and the Cost-Effectiveness Analysis Registry from inception to 31 December, 2022, for relevant economic evaluations, which were critically appraised using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) and Bias in Economic Evaluation (ECOBIAS) criteria. The costs, quality-adjusted life-years, incremental cost-effectiveness ratios and cost-effectiveness thresholds were qualitatively analysed. Net monetary benefits at different decision thresholds were also computed. Subgroup analyses addressing the heterogeneity of economic outcomes were conducted. All costs were adjusted to 2023 international dollar (US$) values using the CCEMG-EPPI-Centre cost converter.

RESULTS

Thirty-nine economic evaluations that evaluated dapagliflozin and empagliflozin in patients with heart failure were found: 32 for the left ventricular ejection fraction (LVEF) ≤ 40% and seven for LVEF > 40%. Sodium-glucose cotransporter-2 inhibitors were cost-effective in all but two economic evaluations for LVEF > 40%. Economic outcomes varied widely, but favoured SGLT2i use in LVEF ≤ 40% over LVEF > 40% and upper-middle income over high-income countries. At a threshold of US$30,000/quality-adjusted life-year, ~ 90% of high to upper-middle income countries would consider SGLT2i cost-effective for heart failure treatment. The generalisability of study findings to low- and low-middle income countries is limited because of insufficient evidence.

CONCLUSIONS

Using SGLT2i to treat heart failure is cost-effective, with more certainty in LVEF ≤ 40% compared to LVEF > 40%. Policymakers in jurisdictions where economic evaluations are not available could potentially use this study's findings to make informed decisions about treatment adoption.

The use of cost-effectiveness analysis for health benefit package design - should countries follow a sectoral, incremental or hybrid approach?

BACKGROUND

Countries around the world are increasingly rethinking the design of their health benefit package to achieve universal health coverage. Countries can periodically revise their packages on the basis of sectoral cost-effectiveness analyses, i.e. by evaluating a broad set of services against a 'doing nothing' scenario using a budget constraint. Alternatively, they can use incremental cost-effectiveness analyses, i.e. to evaluate specific services against current practice using a threshold. In addition, countries may employ hybrid approaches which combines elements of sectoral and incremental cost-effectiveness analysis - a country may e.g. not evaluate the comprehensive set of all services but rather relatively small sets of services targeting a certain condition. However, there is little practical guidance for countries as to which kind of approach they should follow.

METHODS

The present study was based on expert consultation. We refined the typology of approaches of cost-effectiveness analysis for benefit package design, identified factors that should be considered in the choice of approach, and developed recommendations. We reached consensus among experts over the course of several review rounds.

RESULTS

Sectoral cost-effectiveness analysis is especially suited in contexts with large allocative inefficiencies in current service provision and can, in theory, realize large efficiency gains. However, it may be challenging to implement a comprehensive redesign of the package in practice. Incremental cost-effectiveness analysis is especially relevant in contexts where specific new services may impact the sustainability of the health system. It may potentially support efficiency improvement, but its focus has typically been on new services while existing inefficiencies remain unchallenged. The use of hybrid approach may be a way forward to address the strengths and weaknesses of sectoral and incremental analysis areas. Such analysis may be especially useful to target disease areas with suspected high inefficiencies in service provision, and would then make good use of the available research capacity and be politically rewarding. However, disease-specific analyses bear the risk of not addressing resource allocation inefficiencies across disease areas.

CONCLUSIONS

Countries should carefully select their approach of cost-effectiveness analyses for benefit package design, based on their decision-making context.

Cost-Effectiveness of Four Tobacco Control Interventions in Mongolia

INTRODUCTION

The aim of this study is to quantify the cost-effectiveness of four tobacco control interventions: Tobacco taxation, mass media campaigns, school programs, and cessation support, and to illustrate how available evaluation tools can be adapted to the local setting.

AIMS AND METHODS

We used the dynamic population health modeling-health impact assessment tool to project the future smoking prevalence associated with the interventions and to simulate the resulting smoking-related disease burden over time. Applying the most recent available national Mongolian data as input, the costs and effects of four interventions were compared to a business-as-usual scenario, resulting in costs per life year gained and per disability-adjusted life years (DALYs) averted.

RESULTS

Three years after implementation, all interventions reduce the prevalence of current smoking, with the strongest reduction observed with the increase in tobacco tax (5.1% points), followed by mass media campaigns (1.6% points), school programs (1.3% points), and cessation support interventions (0.6% points). School programs were a cost-saving tobacco control intervention compared to current practice in Mongolia, while the other programs resulted in additional costs compared to business as usual. Compared to the World Health Organization (WHO) thresholds, all interventions would be considered "very cost-effective" in terms of cost per DALY averted (below US$ 4295 per DALY averted) in Mongolia.

CONCLUSIONS

Large-scale interventions such as taxation and mass media campaigns result in both cost-effectiveness and important health benefits in relation to intervention costs. Reducing the prevalence of smoking among the male population would be particularly worthwhile in Mongolia.

IMPLICATIONS

This study shows that in Mongolia school programs were a cost-saving intervention, while the cost-effectiveness ratios were US$ 25 per disability-adjusted life year (DALY) averted for mass media campaigns, US$ 74 for taxation, and US$ 1961 for cessation support interventions. Compared to the WHO thresholds, all interventions would be considered "very cost-effective" in terms of expenses per DALY averted ( Collapse

Upfront DPYD Genotype-Guided Treatment for Fluoropyrimidine-Based Chemotherapy in Advanced and Metastatic Colorectal Cancer: A Cost-Effectiveness Analysis

OBJECTIVES

Fluoropyrimidines are the most widely used chemotherapy drugs for advanced and metastatic colorectal cancer (CRC). Individuals with certain DPYD gene variants are exposed to an increased risk of severe fluoropyrimidine-related toxicities. This study aimed to evaluate the cost-effectiveness of preemptive DPYD genotyping to guide fluoropyrimidine therapy in patients with advanced or metastatic CRC.

METHODS

Overall survival of DPYD wild-type patients who received a standard dose and variant carriers treated with a reduced dose were analyzed by parametric survival models. A decision tree and a partitioned survival analysis model with a lifetime horizon were designed, taking the Iranian healthcare perspective. Input parameters were extracted from the literature or expert opinion. To address parameter uncertainty, scenario and sensitivity analyses were also performed.

RESULTS

Compared with no screening, the genotype-guided treatment strategy was cost-saving ($41.7). Nevertheless, due to a possible reduction in the survival of patients receiving reduced-dose regimens, it was associated with fewer quality-adjusted life-years (9.45 vs 9.28). In sensitivity analyses, the prevalence of DPYD variants had the most significant impact on the incremental cost-effectiveness ratio. The genotyping strategy would remain cost-saving, as long as the genotyping cost is < $49 per test. In a scenario in which we assumed equal efficacy for the 2 strategies, genotyping was the dominant strategy, associated with less costs (∼$1) and more quality-adjusted life-years (0.1292).

CONCLUSIONS

DPYD genotyping to guide fluoropyrimidine treatment in patients with advanced or metastatic CRC is cost-saving from the perspective of the Iranian health system.

Validating the rigour of adaptive methods of economic evaluation

BACKGROUND

There has been a lot of debate on how to 'generalise' or 'translate' findings of economic evaluation (EE) or health technology assessment (HTA) to other country contexts. Researchers have used various adaptive HTA (aHTA) methods like model-adaptation, price-benchmarking, scorecard-approach, etc., for transferring evidence from one country to other. This study was undertaken to assess the degree of accuracy in results generated from aHTA approaches specifically for EE.

METHODS

By applying selected aHTA approaches, we adapted findings of globally published EE to Indian context. The first-step required identifying two interventions for which Indian EE (referred to as the 'Indian reference study') has been conducted. The next-step involved identification of globally published EE. The third-step required undertaking quality and transferability check. In the fourth step, outcomes of EE meeting transferability standards, were adapted using selected aHTA approaches. Lastly, adapted results were compared with findings of the Indian reference study.

RESULTS

The adapted cost estimates varied considerably, while adapted quality-adjusted life-years did not differ much, when matched with the Indian reference study. For intervention I (trastuzumab), adapted absolute costs were 11 and 6 times higher than the costs reported in the Indian reference study for control and intervention arms, respectively. Likewise, adapted incremental cost and incremental cost-effectiveness ratio (ICER) were around 3.5-8 times higher than the values reported in the Indian reference study. For intervention II (intensity-modulated radiation therapy), adapted absolute cost was 35% and 12% lower for the comparator and intervention arms, respectively, than the values reported in the Indian reference study. The mean incremental cost and ICER were 2.5 times and 1.5 times higher, respectively, than the Indian reference study values.

CONCLUSION

We conclude that findings from aHTA methods should be interpreted with caution. There is a need to develop more robust aHTA approaches for cost adjustment. aHTA may be used for 'topic prioritisation' within the overall HTA process, whereby interventions which are highly cost-ineffective, can be directly ruled out, thus saving time and resources for conducting full HTA for interventions that are not well studied or where evidence is inconclusive.

Economic evaluations of non-communicable diseases conducted in Sub-Saharan Africa: a critical review of data sources

BACKGROUND

Policymakers in sub-Saharan Africa (SSA) face challenging decisions regarding the allocation of health resources. Economic evaluations can help decision makers to determine which health interventions should be funded and or included in their benefits package. A major problem is whether the evaluations incorporated data from sources that are reliable and relevant to the country of interest. We aimed to review the quality of the data sources used in all published economic evaluations for cardiovascular disease and diabetes in SSA.

METHODS

We systematically searched selected databases for all published economic evaluations for CVD and diabetes in SSA. We modified a hierarchy of data sources and used a reference case to measure the adherence to reporting and methodological characteristics, and descriptively analysed author statements.

RESULTS

From 7,297 articles retrieved from the search, we selected 35 for study inclusion. Most were modelled evaluations and almost all focused on pharmacological interventions. The studies adhered to the reporting standards but were less adherent to the methodological standards. The quality of data sources varied. The quality level of evidence in the data domains of resource use and costs were generally considered of high quality, with studies often sourcing information from reliable databases within the same jurisdiction. The authors of most studies referred to data sources in the discussion section of the publications highlighting the challenges of obtaining good quality and locally relevant data.

CONCLUSIONS

The data sources in some domains are considered high quality but there remains a need to make substantial improvements in the methodological adherence and overall quality of data sources to provide evidence that is sufficiently robust to support decision making in SSA within the context of UHC and health benefits plans. Many SSA governments will need to strengthen and build their capacity to conduct economic evaluations of interventions and health technology assessment for improved priority setting. This capacity building includes enhancing local infrastructures for routine data production and management. If many of the policy makers are using economic evaluations to guide resource allocation, it is imperative that the evidence used is of the feasibly highest quality.

Cost-effectiveness of targeted treatment vs chemoimmunotherapy in treatment-naive unfit CLL without TP53 aberrations

Several targeted treatments, such as venetoclax + obinutuzumab (VenO) and ibrutinib, have been developed to treat patients with treatment-naive chronic lymphocytic leukemia (CLL) and have been shown to improve progression-free survival compared with chlorambucil + obinutuzumab (ClbO). However, novel targeted agents are associated with a significant cost investment. The objective of this study was to investigate the cost-effectiveness of VenO compared with ClbO and ibrutinib in treatment-naive CLL without del17p/TP53 mutation in Denmark. We used a decision-analytic modeling approach to simulate hypothetical cohorts of patients with CLL from the initiation of first-line treatment to death, including the full treatment pathway and second-line therapy. VenO, ClbO, or ibrutinib was included as first-line therapy followed by either Ven + rituximab or ibrutinib. Model outcomes were expected quality-adjusted life years (QALYs), life years (LYs), and cost per patient, which were used to calculate incremental cost-effectiveness ratios (ICERs) with a willingness to pay from €23 600 to €35 600 per QALY. Compared with ClbO, VenO was associated with a QALY gain of 1.30 (1.42 LYs) over a lifetime. The incremental cost was €12 360, resulting in an ICER of €9491 per QALY gained, indicating that VenO is cost-effective. Compared with VenO, ibrutinib was associated with a QALY gain of 0.82 (1.74 LYs) but at a substantially increased incremental cost of €247 488 over a lifetime horizon. The ICER was €302 156 per QALY, indicating that ibrutinib in first-line treatment would not be considered cost-effective in Danish health care, compared with VenO. Future analyses in fit patients with CLL are needed to determine the cost-effectiveness of VenO.

Costs of fall injuries in the STRIDE study: an economic evaluation of healthcare system heterogeneity and heterogeneity of treatment effect

OBJECTIVES

The Strategies to Reduce Injuries and Develop Confidence in Elders (STRIDE) Study cluster-randomized 86 primary care practices in 10 healthcare systems to a patient-centered multifactorial fall injury prevention intervention or enhanced usual care, enrolling 5451 participants. We estimated total healthcare costs from participant-reported fall injuries receiving medical attention (FIMA) that were averted by the STRIDE intervention and tested for healthcare-system-level heterogeneity and heterogeneity of treatment effect (HTE).

METHODS

Participants were community-dwelling adults age ≥ 70 at increased fall injury risk. We estimated practice-level total costs per person-year of follow-up (PYF), assigning unit costs to FIMA with and without an overnight hospital stay. Using independent variables for treatment arm, healthcare system, and their interaction, we fit a generalized linear model with log link, log follow-up time offset, and Tweedie error distribution.

RESULTS

Unadjusted total costs per PYF were $2,034 (intervention) and $2,289 (control). The adjusted (intervention minus control) cost difference per PYF was -$167 (95% confidence interval (CI), -$491, $216). Cost heterogeneity by healthcare system was present (p = 0.035), as well as HTE (p = 0.090). Adjusted total costs per PYF in control practices varied from $1,529 to $3,684 for individual healthcare systems; one system with mean intervention minus control costs of -$2092 (95% CI, -$3,686 to -$944) per PYF accounted for HTE, but not healthcare system cost heterogeneity.

CONCLUSIONS

We observed substantial heterogeneity of healthcare system costs in the STRIDE study, with small reductions in healthcare costs for FIMA in the STRIDE intervention accounted for by a single healthcare system.

Cost-effectiveness of maintenance niraparib with an individualized starting dosage in patients with platinum-sensitive recurrent ovarian cancer in China

Objective: Niraparib improved survival in platinum-sensitive recurrent ovarian cancer (PSROC) patients versus routine surveillance, accompanied by increased costs. Based on the NORA trial, we evaluated for the first time the cost-effectiveness of maintenance niraparib with individualized starting dosage (ISD) in China. Methods: A Markov model was developed to simulate the costs and health outcomes of each strategy. The total costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICERs) were measured. One-way and probabilistic sensitivity analysis were performed to estimate model robustness. Scenario analyses were also conducted. Results: Compared to routine surveillance, niraparib additionally increased QALYs by 0.59 and 0.30 in populations with and without germline BRCA (gBRCA) mutations, with incremental costs of $10,860.79 and $12,098.54, respectively. The ICERs of niraparib over routine surveillance were $18,653.67/QALY and $39,212.99/QALY. At a willingness-to-pay (WTP) threshold of $37,488/QALY, the ISD enhanced the likelihood of cost-effectiveness from 9.35% to 30.73% in the gBRCA-mutated group and from 0.77% to 11.74% in the non-gBRCA mutated population. The probability of niraparib being cost-effective in the region with the highest per capita Gross Domestic Product (GDP) in China was 74.23% and 76.10% in the gBRCA-mutated and non-gBRCA mutated population, respectively. Niraparib was 100% cost-effective for National Basic Medical Insurance beneficiaries under the above WTP thresholds. Conclusion: Compared to routine surveillance, the ISD of niraparib for maintenance treatment of PSROC is cost-effective in the gBRCA-mutated population and more effective but costly in the non-gBRCA mutated patients. The optimized niraparib price, economic status, and health insurance coverage may benefit the economic outcome.

National health technology assessment in Turkiye after a decade: are key principles followed?

BACKGROUND

Health technology assessment (HTA) is growing in low- and middle-income countries (LMICs) to ensure optimal use of limited resources. However, the impact of HTAs on decision making in LMICs has been limited. The study aimed to provide an overview of Turkiye's progress since establishing the first HTA agency in 2012.

METHODS

The web sites of three national HTA agencies in Turkiye were searched for HTA guidelines and national HTA reports. The HTA guidelines were assessed by two researchers independently against the key principles of HTA developed by Drummond et al., and the HTA reports against the national guidelines.

RESULTS

The study included one HTA guideline and eight national HTA reports. The guideline included very limited technical guidance. Compliance with the principles was poor to moderate, and significant methodological limitations were identified. The reports were inconsistent regarding the scope and the HTA assessment criteria. The link between HTA findings, HTA decision making, and health policies were not clear.

DISCUSSION

The inconsistencies between the reports and the methodological limitations demonstrate the need for national HTA guidelines. Improving the characteristics of the HTA might impact implementation. Among the key issues is transparency regarding priority setting, the HTA process, and decision making.

CONCLUSION

Establishing and adopting national HTA guidelines at international standards is needed. Involving external scientific committees and health economists in the HTA processes might help ensure that the key principles of HTA are followed. The study findings might be helpful for countries that are developing their HTA systems.

Standard diagnostics with and without urine-based lipoarabinomannan testing for tuberculosis disease in HIV-infected patients in a high-burden setting-A cost-effectiveness analysis

BACKGROUND

Recent clinical findings reported the reduced mortality associated with treatment guided by sputum-based molecular test with urine-based lipoarabinomannan (LAM) assay for tuberculosis (TB) disease in HIV-infected individuals. We aimed to evaluate the cost-effectiveness of sputum-based Xpert tests with and without urine-based LAM assays among HIV-infected individuals with signs and symptoms of TB disease (TBD) from the perspective of South African healthcare providers.

METHODS

A one-year decision-analytic model was constructed to simulate TB-related outcomes of 7 strategies: Sputum smear microscope (SSM), Xpert, Xpert Ultra, Xpert with AlereLAM, Xpert Ultra with AlereLAM, Xpert with FujiLAM, and Xpert Ultra with FujiLAM, in a hypothetical cohort of adult HIV-infected individuals with signs and symptoms of TB. The model outcomes were TB-related direct medical cost, mortality, early treatment, disability-adjusted life-years (DALYs) and incremental cost per DALY averted (ICER). The model inputs were retrieved from literature and public data. Base-case analysis and sensitivity analysis were conducted.

RESULTS

In the base-case analysis, the Xpert Ultra with FujiLAM strategy showed the highest incidence of early treatment (267.7 per 1000 tested) and lowest mortality (29.0 per 1000 tested), with ICER = 676.9 USD/DALY averted. Probabilistic sensitivity analysis of 10,000 Monte Carlo simulations showed the cost-effective probability of Xpert Ultra with FujiLAM was the highest of all 7 strategies at the willingness-to-pay (WTP) threshold >202USD/DALY averted.

CONCLUSION

Standard sputum-based TB diagnostic Xpert Ultra with urine-based FujiLAM for TBD testing in HIV-infected individuals appears to be the preferred cost-effective strategy from the perspective of the health service provider of South Africa.

Implementing a Managed Entry Agreement Framework in Cyprus

INTRODUCTION

The aim of this study is to explore the current practice in Cyprus regarding the introduction and reimbursement of innovative pharmaceuticals through Managed Entry Agreements (MEA), assess its operational context, and suggest approaches toward spanning the knowledge gap consequential to these efforts, especially the barriers of a small country context.

AREAS COVERED

The recent introduction of a National Health System (NHS), brought about fundamental reforms in Cyprus' Healthcare sector. Among such reforms, of particular interest, has been the introduction of a Managed Entry Agreements (MEA) mechanism. The first preliminary results indicate that despite being a small and unattractive market, Cyprus can apply a substantial MEA program. Concomitantly, it annotates the need to design an operational framework which should include, the definition of important technical parameters, clear demarcation of the scope, cooperation principles ensuring the effective operation of scientific committees, and clear delineation of what 'value' is. Moreover, in the context of the unified healthcare market, budget transfers should be considered, which could alleviate the inordinate budget impact of new products, which nevertheless will cut down on hospital expenditures. Narrative synthesis and health policy analysis-related resources were used.

EXPERT OPINION

The implementation of MEA in Cyprus provides an ideal testing ground for innovative reimbursement approaches. This will streamline the country's efforts toward reimbursement of innovation, while concomitantly add to the collective MEA experience.

Critical Appraisal of Decision Models Used for the Economic Evaluation of Bladder Cancer Screening and Diagnosis: A Systematic Review

BACKGROUND AND OBJECTIVE

Bladder cancer is common among current and former smokers. High bladder cancer mortality may be decreased through early diagnosis and screening. The aim of this study was to appraise decision models used for the economic evaluation of bladder cancer screening and diagnosis, and to summarise the main outcomes of these models.

METHODS

MEDLINE via PubMed, Embase, EconLit and Web of Science databases was systematically searched from January 2006 to May 2022 for modelling studies that assessed the cost effectiveness of bladder cancer screening and diagnostic interventions. Articles were appraised according to Patient, Intervention, Comparator and Outcome (PICO) characteristics, modelling methods, model structures and data sources. The quality of the studies was also appraised using the Philips checklist by two independent reviewers.

RESULTS

Searches identified 3082 potentially relevant studies, which resulted in 18 articles that met our inclusion criteria. Four of these articles were on bladder cancer screening, and the remaining 14 were diagnostic or surveillance interventions. Two of the four screening models were individual-level simulations. All screening models (n = 4, with three on a high-risk population and one on a general population) concluded that screening is either cost saving or cost effective with cost-effectiveness ratios lower than $53,000/life-years saved. Disease prevalence was a strong determinant of cost effectiveness. Diagnostic models (n = 14) assessed multiple interventions; white light cystoscopy was the most common intervention and was considered cost effective in all studies (n = 4). Screening models relied largely on published evidence generalised from other countries and did not report the validation of their predictions to external data. Almost all diagnostic models (n = 13 out of 14) had a time horizon of 5 years or less and most of the models (n = 11) did not incorporate health-related utilities. In both screening and diagnostic models, epidemiological inputs were based on expert elicitation, assumptions or international evidence of uncertain generalisability. In modelling disease, seven models did not use a standard classification system to define cancer states, others used risk-based, numerical or a Tumour, Node, Metastasis classification. Despite including certain components of disease onset or progression, no models included a complete and coherent model of the natural history of bladder cancer (i.e. simulating the progression of asymptomatic primary bladder cancer from cancer onset, i.e. in the absence of treatment).

CONCLUSIONS

The variation in natural history model structures and the lack of data for model parameterisation suggest that research in bladder cancer early detection and screening is at an early stage of development. Appropriate characterisation and analysis of uncertainty in bladder cancer models should be considered a priority.

Cost-Effectiveness of Venetoclax Plus Obinutuzumab Versus Chlorambucil Plus Obinutuzumab for the First-Line Treatment of Adult Patients With Chronic Lymphocytic Leukemia: An Extended Societal View

OBJECTIVES

Efficacy of venetoclax plus obinutuzumab (VenO) compared with chlorambucil plus obinutuzumab (ClbO) for treatment-naïve adult patients with chronic lymphocytic leukemia (CLL) with coexisting medical conditions was investigated in CLL14 (NCT02242942). Our aim was to evaluate the cost-effectiveness of VenO versus ClbO for these patients from a Dutch societal perspective.

METHODS

A 3-state partitioned survival model was constructed to evaluate the cost-effectiveness of VenO. The outcome of the analysis was the incremental cost-effectiveness ratio (ICER) with effectiveness measured in quality-adjusted life-years (QALYs) gained. Uncertainty was explored through deterministic and probabilistic sensitivity analyses, scenario analyses, and value of information analysis (VOI).

RESULTS

The base case resulted in a discounted ICER -49 928 EUR/QALY gained (with incremental negative costs and positive effects). None of the ICERs resulted from deterministic sensitivity and scenario analyses exceeded the chosen willingness-to-pay threshold of 20 000 EUR/QALY, and > 99% of the iterations in the probabilistic sensitivity analysis were cost-effective. VOI analyses showed a maximum expected value of eliminating all model parameter uncertainty of 183 591 EUR.

CONCLUSIONS

Our study demonstrated VenO being dominant over ClbO in treatment-naïve adult patients with CLL assuming a Dutch societal perspective. We concluded that our results are robust as tested through sensitivity and scenario analyses. Additionally, the VOI analyses confirmed that our current evidence base is strong enough to generate reliable results for our study. Nevertheless, further research based on real-world data or longer follow-up period could further contribute to the robustness of the current study's conclusions.

Barriers and facilitators to implementing priority setting and resource allocation tools in hospital decisions: A systematic review

Health care budgets in high-income countries are having issues coping with unsustainable growth in demand, particularly in the hospital setting. Despite this, implementing tools systematising priority setting and resource allocation decisions has been challenging. This study answers two questions: (1) what are the barriers and facilitators to implementing priority setting tools in the hospital setting of high-income countries? and (2) what is their fidelity? A systematic review using the Cochrane methods was conducted including studies of hospital-related priority setting tools reporting barriers or facilitators for implementation, published after the year 2000. Barriers and facilitators were classified using the Consolidated Framework for Implementation Research (CFIR). Fidelity was assessed using priority setting tool's standards. Out of thirty studies, ten reported program budgeting and marginal analysis (PBMA), twelve multi-criteria decision analysis (MCDA), six health technology assessment (HTA) related frameworks, and two, an ad hoc tool. Barriers and facilitators were outlined across all CFIR domains. Implementation factors not frequently observed, such as 'evidence of previous successful tool application', 'knowledge and beliefs about the intervention' or 'external policy and incentives' were reported. Conversely, some constructs did not yield any barrier or facilitator including 'intervention source' or 'peer pressure'. PBMA studies satisfied the fidelity criteria between 86% and 100%, for MCDA it varied between 36% and 100%, and for HTA it was between 27% and 80%. However, fidelity was not related to implementation. This study is the first to use an implementation science approach. Results represent the starting point for organisations wishing to use priority setting tools in the hospital setting by providing an overview of barriers and facilitators. These factors can be used to assess readiness for implementation or to serve as the foundation for process evaluations. Through our findings, we aim to improve the uptake of priority setting tools and support their sustainable use.

A Comparative Analysis of Anticancer Drug Appraisals Including Managed Entry Agreements in South Korea and England

OBJECTIVES

This study aimed to compare appraisal decisions about anticancer drugs between the health technology assessment (HTA) agencies in Korea and England, and investigate whether the decisions and supporting evidence are comparable.

METHODS

This study identified 49 anticancer drugs listed by the Korean Ministry of Health and Welfare between January 2014 and December 2019. Of those, 46 anticancer drugs for 58 indications were included for analysis. Official appraisal documents from both countries for 58 drug-indication pairs were compared and assessed in terms of clinical and economic evidence. Evidence items and their groups for analysis were predefined.

RESULTS

Three-quarters of cases were recommended with managed entry agreements (MEAs) in England and three-fifths in Korea. Finance-based MEA types were most common in both countries. Korean and English authorities made consistent decisions in 48 cases (83%) when classifying decisions as 'recommended' and 'not recommended', while the degree of agreement lowered to 16 cases (28%) when subdividing decisions according to MEA types. When the evidence base was identical, their decisions were more likely to be consistent. Regarding clinical evidence, while the majority of cases referred to the same pivotal studies, differences between the committees' recognized comparators and the appraisal date caused discrepancies in decisions. Economic evidence, including incremental cost-effectiveness ratio (ICER) estimates, was identical in only 12 cases (21%), which contributed to discrepancies.

CONCLUSION

England relies on economic evaluation, with increasing use of data collection agreements, in contrast with Korea's new procedure exempting companies from providing economic evaluation. While there is possibility for international cooperation in the assessment of clinical evidence, transferability issues exist, particularly with regard to economic evidence.

The Allocation of the Economic Value of Second-Generation Antipsychotics Over the Product Life Cycle: The Case of Risperidone in Sweden and the United Kingdom

OBJECTIVE

This article estimates the life-cycle value of risperidone as representative of second-generation antipsychotics (SGA) relative to haloperidol (first-generation antipsychotics).

METHODS

We estimated the number of patients treated with risperidone in Sweden and the United Kingdom, from 1994 to 2017, using data of usage and volume sales. We collected data from the literature on the effectiveness (quality-adjusted life-years per patient per year), direct costs (health services), and indirect costs (productivity) of risperidone and haloperidol. We proxied the incremental value added by the new class (SGA) using a comparator from the inferior class. Next, we modeled the life-cycle uptake of risperidone to estimate the life-cycle incremental cost (ie, direct, indirect, and medicine costs), incremental quality-adjusted life-years, and net monetary benefit of risperidone. We also assessed the life-cycle distribution of the social surplus between the payer (consumer surplus) and the innovator (producer surplus).

RESULTS

For the United Kingdom, consumer surplus represents around 72% of the total surplus before patent expiration and around 95% after patent expiration. For Sweden, the consumer surplus represents around 94% of the total surplus before patent expiration and around 99% after generic competition.

CONCLUSION

These results suggest that the value added by SGAs to the system is higher than the expected value estimated using cost-effectiveness analysis at launch. Pricing and reimbursement decisions could recognize the full life cycle of value of innovative medicines. This not only presents a challenge of estimation but also of assessing the appropriate division of shares of social value.

Health State Utility Values of Type 2 Diabetes Mellitus and Related Complications: A Systematic Review and Meta-Analysis

OBJECTIVES

This study aims to synthesize health state utility values (HSUVs) of type 2 diabetes mellitus (T2DM) and its related complications published in the literature, conducting a meta-analysis of the data when possible.

METHODS

We conducted a systematic search in MEDLINE and School of Health and Related Research Health Utilities Database repository. Studies focused on T2DM and its complications reporting utility values elicited using direct and indirect methods were selected. We categorized the results according to the instrument to describe health and meta-analyzed them accordingly. Data included in the analysis were pooled in a fixed-effect model by the inverse of variance mean and random-effects DerSimonian-Laird method. Two approaches on sensitivity analysis were performed: leave-one-out method and including data of HSUVs obtained by foreign population value sets.

RESULTS

We identified 70 studies for the meta-analysis from a total of 467 studies. Sufficient data to pool T2DM HSUVs from EQ-5D instrument, hypoglycemia, and stroke were obtained. HSUVs varied from 0.7 to 0.92 in direct valuations, and the pooled mean of 3-level version of EQ-5D studies was 0.772 (95% confidence interval 0.763-0.78) and of 5-level version of EQ-5D 0.815 (95% confidence interval 0.808-0.823). HSUVs of complications varied from 0.739 to 0.843, or reductions of HSUVs between -0.014 and -0.094. In general, HSUVs obtained from 3-level version of EQ-5D and Health Utility Index 3 instruments were lower than those directly elicited. A considerable amount of heterogeneity was observed. Some complications remained unable to be pooled due to scarce of original articles.

CONCLUSIONS

T2DM and its complications have a considerable impact on health-related quality of life. 5-level version of EQ-5D estimates seems comparable with direct elicited HSUVs.

Economic evaluations of interventional opportunities for the management of mental-physical multimorbidity: a systematic review

OBJECTIVES

Economic evaluations of interventions for people with mental-physical multimorbidity, including a depressive disorder, are sparse. This study examines whether such interventions in adults are cost-effective.

DESIGN

A systematic review.

DATA SOURCES

MEDLINE, CINAHL Plus, PsycINFO, Cochrane CENTRAL, Scopus, Web of Science and NHS EED databases were searched until 5 March 2022.

ELIGIBILITY CRITERIA

We included studies involving people aged ≥18 with two or more chronic conditions (one being a depressive disorder). Economic evaluation studies that compared costs and outcomes of interventions were included, and those that assessed only costs or effects were excluded.

DATA EXTRACTION AND SYNTHESIS

Two authors independently assessed risk of bias in included studies using recommended checklists. A narrative analysis of the characteristics and results by type of intervention and levels of healthcare provision was conducted.

RESULTS

A total of 19 studies, all undertaken in high-income countries, met inclusion criteria. Four intervention types were reported: collaborative care, self-management, telephone-based and antidepressant treatment. Most (14 of 19) interventions were implemented at the organisational level and were potentially cost-effective, particularly, the collaborative care for people with depressive disorder and diabetes, comorbid major depression and cancer and depression and multiple long-term conditions. Cost-effectiveness ranged from £206 per quality-adjusted life year (QALY) for collaborative care programmes for older adults with diabetes and depression at primary care clinics (USA) to £79 723 per QALY for combining collaborative care with improved opportunistic screening for adults with depressive disorder and diabetes (England). Conclusions on cost-effectiveness were constrained by methodological aspects of the included studies: choice of perspectives, time horizon and costing methods.

CONCLUSIONS

Economic evaluations of interventions to manage multimorbidity with a depressive disorder are non-existent in low-income and middle-income countries. The design and reporting of future economic evaluations must improve to provide robust conclusions.

Cost-effectiveness in unstable economies: the case of sacubitril/valsartan in heart failure with reduced ejection fraction in Argentina

BACKGROUND

Sacubitril/valsartan (an Angiotensin receptor-neprilysin inhibitor-ARNI) is one of the cornerstones in the management of patients with heart failure with reduced ejection fraction (HFrEF) having demonstrated significant reductions in both mortality and hospitalisations as compared with enalapril. It proved to be a cost-effective treatment in many countries with stable economies. In Argentina, a country with chronic financial instability and a fragmented health care system, the estimation of its cost-effectiveness requires to consider local financial data.

OBJECTIVES

To estimate the cost-effectiveness of sacubitril/valsartan in HFrEF in Argentina.

METHODS

We populated an Excel-based cost-effectiveness model, previously validated, using inputs from the pivotal phase-3 PARADIGM-HF trial and from local sources. As the main problem to consider was the financial instability, we adopted a differential approach to cost discounting based on the opportunity cost of capital. Thus, a discount rate for costs were set at 31.6%, using the BADLAR rate published by the Central Bank of Argentina. Discount for effects were set at 5% as is the current practice. Costs were expressed in Argentinian pesos (ARS). We used the perspective for both the social security and private payers at a 30-year horizon. The primary analysis was the incremental cost-effectiveness ratio (ICER) versus enalapril, the previous standard of care. Alternative scenarios performed included a 5% cost discount rate and 3 a 5-year horizon (as is usually used).

RESULTS

In Argentina the cost-per quality adjusted life-year (QALY) gained for sacubitril/valsartan versus enalapril was 391,158 ARS and 376,665 ARS for a social security and a private payer, respectively, at a 30- year horizon. These ICERs were under the cost- effectiveness threshold of 520,405.79 ARS (1 Gross domestic product (GDP) per capita) suggested by Argentinian health technology assessment bodies. Probabilistic sensitivity analysis showed an acceptability of sacubitril/valsartan as a cost-effective alternative of 86.40% and 88.25% for social security and private payers, respectively.

CONCLUSION

Sacubitril/valsartan is a cost-effective treatment in HFrEF using local inputs that considered the financial instability. For both payers considered the cost per QALY gained are under the cost-effectiveness threshold considered.

A systematic review of discounting in national health economic evaluation guidelines: healthcare value implications

Aim: This review summarizes the discounting approaches recommended in current economic evaluation (EE) guidelines for healthcare programs and interventions. Materials & methods: A systematic review of EE guidelines for healthcare, published up to July 2022, was conducted. Results: A total of 52 EE guidelines were reviewed. The majority of these guidelines recommend equal discounting (80.8%) rather than differential discounting (9.6%). The rationale for equal discounting includes recommendations by the government, consistency with other countries, and economic development. However, the rationale for differential discounting is based on the interest in short-term government bonds and anticipated budget changes. Discussion: This review demonstrates variation in both discounting approaches and rates across EE guidelines and underscores the need for a global consensus on discounting approaches.

How is the Societal Perspective Defined in Health Technology Assessment? Guidelines from Around the Globe

Some researchers have argued that the aim of an economic evaluation should be to offer guidance on resource allocation based on public interest from a societal perspective. The application of a societal perspective in health technology assessment (HTA), while common in many published studies, is not mandated in most countries, and there is limited discussion on what the societal perspective should encompass. This study aimed to systematically compare and contrast the HTA guidelines in different countries. HTA methods guidelines were identified through international HTA networks, such as the Professional Society for Health Economics and Outcomes Research (ISPOR) and Guide to Economic Analysis Research (GEAR). The respective HTA agencies were grouped into two categories: well-established and newly developed, based on the establishment date. Data extracted from the guidelines summarised the methodological details in the reference cases, including specifics on the societal perspective. The database search yielded 46 guidelines, and 65% explicitly considered the societal perspective. The maturity of these agencies is reflected in their attitudes towards the societal perspective; the societal perspective is defined in 73% of the guidelines of well-established agencies and only 56% of those of newly developed agencies. The guidelines from multipayer healthcare systems are more likely to consider the societal perspective. Although most guidelines from the well-established agencies recommend the inclusion of a societal perspective, the types of costs and consequences that should be included and the recommended approaches to valuing them are variable. The direct costs to family and carers were included in 73% of the societal perspective definitions, while non-health outcomes were considered in only 40%. Most HTA guidelines lack clear guidance on what to include under specific perspectives. Considering the recent advancements in economic evaluation methods, it is timely to rethink the role of the societal perspective in HTA guidelines and adopt a more comprehensive perspective to include all costs and consequences of healthcare services.
