Abstract
BACKGROUND Atrial fibrillation (AF) is a severe epidemiological and public health concern among the elderly population worldwide, with substantial economic and social burdens. Economic evaluations can play an essential role in optimizing the utilization of scarce resources. In recent years, the number of economic evaluation studies related to AF has increased due to the rising number of AF patients, the continuous updating of clinical data, and the emergence of real-world evidence. However, there are still deficiencies in model settings and parameter sources in relevant studies. OBJECTIVE This study aims to review the existing economic evaluations of novel oral anticoagulants (NOACs) in patients with AF and summarize the evidence and methods applied. METHODS A comprehensive and systematic search was conducted on electronic databases, including PubMed, Embase, Web of Science (WOS), and The Cochrane Library, from the date of database creation to November 2022. The reporting quality of included literature was assessed using the Consolidated Health Economic Evaluation Reporting Standards 2022 (CHEERS 2022) statement. RESULTS A total of 102 studies were included in the review, with 200 comparisons between NOACs and vitamin K antagonists (VKAs), as well as 58 comparisons between different NOACs. The healthcare sector and payer perspectives were the most common, and accordingly, the majority of the evaluations considered only direct medical costs. Most studies used Markov cohort models with the number of health states ranging from 4 to 29. Of included studies, 80 (78%) considered event recurrence and complications, and 78 (76%) considered discontinuation and second-line therapy. All of the studies applied uncertainty analysis to explore the robustness of the results. Of all 200 NOACs-VKAs comparisons, 149 (75%) showed that NOACs were more cost-effective; this proportion was 84% (139 out of 165) in high-income countries but decreased to 29% (10 out of 35) in middle- and low-income countries. Most (82%) of the 28 items in the CHEERS 2022 checklist were elucidated in the majority of included studies. A minority (only 39%) of included studies demonstrated high reporting quality. CONCLUSION NOACs may be more cost-effective than VKAs in patients with AF, but this conclusion applies to high-income countries, whereas VKAs may be more cost-effective in middle- and low-income countries. The reporting quality of included studies was variable, and certain methodological issues were presented. This study highlights the economic evaluation methodology of NOACs in patients with AF and provides recommendations for modeling methods and future studies.

Oral Anticoagulants for Stroke Prevention in Atrial Fibrillation: A Systematic Review of Economic Evaluations. Value Health Reg Issues 2023; 33:99-108. [PMID: 36402007 DOI: 10.1016/j.vhri.2022.09.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Revised: 08/19/2022] [Accepted: 09/30/2022] [Indexed: 11/18/2022]
Abstract
OBJECTIVES Several studies have evaluated the economic evaluation of a group of medications known as novel oral anticoagulant drugs (NOACs) in recent years. The aim of this study is to review and systematically analyze the cost-utility studies results of warfarin compared with other NOAC drugs in atrial fibrillation patients. METHODS A systematic review was performed to identify all studies evaluating the NOAC medications in comparison with warfarin. For this purpose, PubMed, Cochrane Library, ISI Web of Science, and Scopus were searched from 2013 to 2022. Articles were independently screened with inclusion criteria, and full texts were reviewed. First, the Consolidated Health Economic Evaluation Reporting Standards checklist was used to evaluate the quality of the articles. Then, the costs and outcomes of the studies were analyzed, and findings were appraised critically. RESULTS A total of 84 costs-per-quality-adjusted life-year (QALY) cases were extracted from the studies in which the share of rivaroxaban, edoxaban, apixaban, and dabigatran were 31%, 13%, 29%, and 27%, respectively. The median cost per QALY of rivaroxaban, edoxaban, apixaban, and dabigatran was 21 910$/QALY, 22 096$/QALY, 17 765$/QALY, and 24 161$/QALY, respectively. Subgroup analysis based on perspective showed that dabigatran had the highest incremental cost-effectiveness ratio (ICER) and edoxaban had the lowest ICER value. Edoxaban and apixaban had the highest and the lowest cost per QALY from an insurance perspective, respectively. CONCLUSION Despite the differences and variations in the economic evaluation studies of NOAC drugs, these drugs have shown acceptable cost-effectiveness in developed and developing countries. Among NOAC drugs, apixaban has the lowest ICER and the highest cost-effectiveness.

Abstract
OBJECTIVES To assess cost-effectiveness of direct oral anticoagulants (DOACs) compared with vitamin K antagonists (VKAs) for stroke prevention in atrial fibrillation (AF) by pooling incremental net benefits (INBs). DESIGN Systematic review and meta-analysis. SETTING We searched PubMed, Scopus and Centre for Evaluation of Value and Risks in Health Registry from inception to December 2019. PARTICIPANTS Patients with AF. MAIN OUTCOME MEASURES The INB was defined as a difference of incremental effectiveness multiplied by willing to pay threshold minus the incremental cost; a positive INB indicated favour treatment. These INBs were pooled (stratified by level of country income, perspective, time-horizon, model types) with a random-effects model if heterogeneity existed, otherwise a fixed effects model was applied. Heterogeneity was assessed using Q test and I2 statistic. Risk of bias was assessed using the economic evaluations bias (ECOBIAS) checklist. RESULTS A total of 100 eligible economic evaluation studies (224 comparisons) were included. For high-income countries (HICs) from a third-party payer (TPP) perspective, the pooled INBs for DOAC versus VKA pairs were significantly cost-effective with INBs (95% CI) of $6632 ($2961.67 to $10 303.72; I2=59.9%), $6353.24 ($4076.03 to $8630.45; I2=0%), $7664.58 ($2979.79 to $12 349.37; I2=0%) and $8573.07 ($1877.05 to $15 269.09; I2=0%) for dabigatran, apixaban, rivaroxaban and edoxaban relative to VKA, respectively but only dabigatran was significantly cost-effective from societal perspective (SP) with an INB of $11 746.96 ($2429.34 to $21 064.59; I2=52.4%). The pooled INBs of all comparisons for upper-middle income countries (UMICs) were not significantly cost-effective. The ECOBIAS checklist indicated that risk of bias was mostly low for most items with the exception of five items which should be less influenced on pooling INBs. CONCLUSIONS Our meta-analysis provides comprehensive economic evidence that allows policy makers to generalise cost-effectiveness data to their local context. All DOACs may be cost-effective compared with VKA in HICs with TPP perspective. The pooling results produced moderate to high heterogeneity particularly in UMICs. Further studies are required to inform UMICs with SP. PROSPERO REGISTERATION NUMBER CRD 42019146610.

Abstract
Background: Dabigatran is a univalent low-molecular-weight direct thrombin inhibitor which was developed as an alternative to vitamin K antagonists (VKAs). However, the safety of dabigatran remains controversial so far. In this study, we aimed to compare the risk of bleeding, fatal adverse events, and the all-cause mortality of dabigatran with those of the control group by a systematic review and meta-analysis of randomized controlled trials. Methods: We systematically searched PubMed, Web of Science, Cochrane Library, Medline, Embase, Wanfang database, Clinical trial, China National Knowledge Infrastructure Chinese Scientific Journal database (VIP), and Chinese Biological Medicine database (CBM), for clinical trials on conventional treatments compared with dabigatran, published between January 2014 and July 2020. The reported outcomes, including the endpoints of primary safety, were systematically investigated. Results: Seven RCTs (n = 10,743) were included in the present systematic review. Compared to the control groups, dabigatran was not associated with an increased risk of major bleeding (relative risk [RR] 0.86, 95% confidence interval [CI]: 0.61 to 1.21, p = 0.06), intracranial hemorrhage (RR 0.89, 95% CI: 0.58 to 1.36, p = 0.41), fatal adverse reactions (RR 0.87, 95% CI: 0.65 to 1.17, p = 0.66), all-cause mortality (RR 0.88, 95% CI: 0.70 to 1.11, p = 0.45, I2 = 0%), and significantly reduced risk of clinically relevant non-major bleeding (RR 0.96, 95% CI: 0.65 to 1.42, p = 0.0007). However, dabigatran is associated with an increased risk of gastrointestinal (GI) bleeding (RR 1.78, 95% CI: 1.02 to 3.13, p = 0.05). Conclusion: Dabigatran has a favorable safety profile in terms of major bleeding, intracranial hemorrhage, and life-threatening events, among other safety outcomes. The present study suggested that dabigatran may be a suitable alternative to VKAs as an oral anticoagulant. However, more data are necessary to clarify the incidence of other adverse events and serious adverse reactions.

Abstract
RESUMO A Avaliação de Tecnologias em Saúde (ATS) respalda políticas públicas na gestão de tecnologias em diversos países. No Brasil, a institucionalização da ATS se iniciou em 2000, no Ministério da Saúde, e contou com a participação da Agência Nacional de Saúde Suplementar (ANS). Contudo, o sistema público e a saúde suplementar trilharam diferentes caminhos. Processos distintos de ATS podem gerar retrabalho, ineficiência e aumentar as inequidades entre o público e o privado. O objetivo desta pesquisa foi identificar a dualidade entre o público e o privado relativa aos modelos de ATS implantados no País. Realizou-se uma revisão de escopo da literatura no período de 2000 a 2019 nas bases de dados Medline, Scopus, Web of Science e Lilacs. Também se realizou análise de documentos da ANS relativos ao processo de ATS na saúde suplementar. A revisão da literatura constatou a escassez de artigos sobre o tema, enquanto a análise documental permitiu traçar uma linha do tempo com os principais marcos referentes ao processo de ATS da Agência. Concluiu-se que a coordenação nacional de um modelo de ATS é desejada, visando a aumentar a transparência das instituições, a maior credibilidade das suas decisões, maior eficiência do processo e proporcionar maior equidade.
