    背景:欧洲肿瘤药物的报销过程发生在一个复杂的决策过程中,成员国之间存在差异。国家之间的区别引发了社会辩论,因为有必要平衡获得药品和卫生系统的可持续性。
    目的:我们旨在审查与欧洲肿瘤药物的报销决定或卫生技术署推荐相关因素的证据。
    方法:从开始到2023年8月,在两个数据库中进行了系统的文献检索。成对地进行筛选和数据提取。
    结果:纳入了13篇文章,涵盖了来自11个国家的数据。七篇文章表明,具有成本效益的(C-E)药物和较低的成本效益增量比(ICER)具有较高的报销可能性。疾病的严重程度可能会影响财务协议的报销决定。临床结果的改善,显著的临床获益(p<0.01)或总生存期增加(p<0.05)呈正相关.孤儿药物指定的影响因国家而异,但积极的决定通常是在特定条件下实现的。临床和C-E不确定性经常导致通过财务协议或基于结果的条件进行报销。社会人口因素:社会医疗保险制度,较高的国内生产总值和较大的老年人口与报销呈正相关(p<0.01)。
    结论:需要进一步研究欧洲报销决定的关键决定因素,并开发能够有效解决和克服成本和有效性不确定性的药物获取模型。
    BACKGROUND: Reimbursement process of oncology drugs in Europe occurs within a complex decision-making process that varies between Member States. Distinctions between the States trigger societal debates since it is necessary to balance access to medicines and health systems sustainability.
    OBJECTIVE: We aimed to review the evidence concerning factors associated with the reimbursement decision or Health Technology Agency recommendation of oncology drugs in Europe.
    METHODS: A systematic literature search was performed in two databases from inception to august 2023. Screening and data extraction were performed by pairs.
    RESULTS: Thirteen articles were included and encompassed data from 11 nations. Seven articles showed that cost-effective (C-E) drugs and lower Incremental Cost-Effectiveness Ratios (ICERs) had higher likelihood of reimbursement. Disease severity might influence the reimbursement decision with financial agreements. Improvement in clinical outcomes, substantial clinical benefit (p < 0.01) or overall survival gains (p < 0.05) were positively associated. Orphan drug designation impact varies between countries but positive decisions are usually achieved under specific conditions. Clinical and C-E uncertainty frequently led to reimbursement with financial agreements or outcomes-based conditions. Sociodemographic factors as: social health insurance system, higher Gross Domestic Product and larger elderly population were positively associated with reimbursement (p < 0.01).
    CONCLUSIONS: There is a need for further research into key determinants of reimbursement decisions in Europe and the development of drug access models that can effectively address and overcome costs and effectiveness uncertainties.

    从珊瑚礁捕获的野生鱼,地球上最受威胁的生态系统之一,继续供应海洋水族馆贸易。尽管在进口过程中进行了海关和兽医检查,关于这一全球行业的全面数据仍然匮乏。这项研究提供了按价值计算的最大进口市场的综合数据,欧盟(EU):年贸易额为2400万欧元,详述主要出口国和进口国,以及2014年至2021年间进口的2600万份标本的物种和科。基于交易标本数量的观察名单警报系统,进口趋势,并根据FishBase和IUCN红色名录保护状况提出了脆弱性指数,提供关于哪些物种需要当局更严格审查的关键信息。虽然欧洲贸易控制和专家系统(TRACES)以电子方式监控活动物的运动,以快速应对生物安全风险,三分之一的海洋观赏鱼进口缺乏物种级信息。经过微小的调整,TRACES具有显着增强数据粒度和野生动植物贸易监测的潜力,海洋观赏鱼是一个有趣的案例研究,以验证这种方法。
    Wild-caught fish from coral reefs, one of the most threatened ecosystems on the planet, continue to supply the marine aquarium trade. Despite customs and veterinary checks during imports, comprehensive data on this global industry remain scarce. This study provides consolidated data on the largest import market by value, the European Union (EU): a 24-million-euro annual trade value, detailing the main exporting and importing countries, as well as the species and families of the 26 million specimens imported between 2014 and 2021. A watchlist alert system based on the number of specimens traded, import trends, and vulnerability index according to FishBase and the IUCN Red List conservation status is presented, providing key information on which species should require closer scrutiny by authorities. While the European TRAde Control and Expert System (TRACES) electronically monitors the movement of live animals to respond quickly to biosecurity risks, one-third of marine ornamental fish imported lack species-level information. With minor adjustments, TRACES holds the potential to significantly enhance data granularity and the monitoring of wildlife trade, with marine ornamental fish being an interesting case study to validate this approach.

    目的:这篇叙述性综述旨在提出成像中的价值概念,并探讨为什么我们进行低价值程序,如何减少这种浪费的使用,以及我们可以从减少低价值成像中获得什么。
    结果:对患者进行低值成像会导致数千公吨的二氧化碳排放,每年花费数十亿美元。低值成像减少20%,我们将减少与720万个程序相关的资源浪费,同时,降低偶发瘤的风险,过度诊断,和过度治疗,并减少需要高价值影像服务的患者的等待时间。需要针对社会和医疗保健各个层面的障碍采取多成分举措,以减少低价值成像。放射技师是医学成像的关键角色,可以通过以下方式为这项工作做出重大贡献:和放射科医生一起,推荐人,和经理,确保所进行的所有成像程序在可持续性的四个方面都是可持续的:价值,成本,风险,和环境。
    结论:考虑到四个关键维度(价值,成本,辐射,和环境)应该在社会和医疗保健的各个层面上,从政府管理到个人医护人员。放射技师对于获得可持续性至关重要,以确保仅进行可持续的成像程序。
    结论:在评估成像程序的适当性时,我们需要考虑环境,安全,有效性,和效率。为了获得这个,我们需要在当地集体和协调的努力,全国,并在国际上提供可持续的成像服务。
    OBJECTIVE: This narrative review aims to present the concept of value in imaging and explore why we conduct low-value procedures, how to reduce this wasteful use, and what we could gain from reducing low-value imaging.
    RESULTS: Imaging of low value to the patient contributes to thousands of metric tons of CO2 emissions, costing several billion US dollars annually. With a 20% reduction in low-value imaging, we would reduce the waste of resources related to 7.2 million procedures and, at the same time, reduce the risk of incidentalomas, overdiagnosis, and overtreatment and reduce wait times for patients in need of imaging services of high value. Multi-component initiatives targeting barriers in all levels of society and healthcare are needed to reduce low-value imaging. Radiographers are key actors in medical imaging and can make substantial contributions to this effort by, together with the radiologists, referrers, and managers, ensuring that all imaging procedures conducted are sustainable along four dimensions of sustainability: value, cost, risk, and environment.
    CONCLUSIONS: Efforts to secure sustainable imaging considering the four crucial dimensions (value, cost, radiation, and environment) should be made at all levels of society and healthcare, from governmental management to the individual healthcare worker. Radiographers are vital in obtaining sustainability to ensure only sustainable imaging procedures are conducted.
    CONCLUSIONS: When assessing the appropriateness of imaging procedures, we need to consider the environment, safety, effectiveness, and efficiency. To obtain this, we need a collective and coordinated effort locally, nationally, and internationally to deliver sustainable imaging services.

    用于治疗黑色素瘤的Mohs显微手术(MMS)比广泛的局部切除术(WLE)具有多种优势,包括完整的组织学边缘评估,当天切除和闭合,并在关键解剖部位保留健康组织。最近,大量的临床数据证明了MMS治疗黑色素瘤的有效性,导致新出现的患者安全考虑发生的治疗费用,肿瘤分期的风险,前哨淋巴结活检(SLNB)的护理协调失败。彩信提供保险箱,有效,以及基于价值的原位黑色素瘤(MIS)和侵袭性黑色素瘤(IM)治疗,特别是在冷冻切片上使用免疫组织化学。与WLE相比,MMS治疗显示类似或改善局部肿瘤复发的结果,黑色素瘤特异性生存率,和长期随访的总生存率。肿瘤分期风险低,如果存在,对临床管理的改变是最小的。对于符合条件的头颈部IM病例,应在MMS之前进行SLNB的讨论。虽然具有挑战性,已经证明了SLNB与MMS的成功多学科协调。在这里,我们对MMS治疗皮肤黑色素瘤的证据进行了详细的临床回顾,并就解决目前围绕MIS和IM外科治疗模式不断发展的争议提出了建议.
    Mohs Micrographic Surgery (MMS) for treatment of melanoma offers several advantages over wide local excision (WLE), including complete histologic margin evaluation, same-day resection and closure, and sparing of healthy tissue in critical anatomic sites. Recently, a large volume of clinical data demonstrating efficacy in MMS treatment of melanoma was published, leading to emerging patient safety considerations of incurred treatment costs, risk of tumor upstaging, and failure of care coordination for sentinel lymph node biopsy (SLNB). MMS offers a safe, effective, and value-based treatment for both melanoma in situ (MIS) and invasive melanoma (IM), particularly with immunohistochemistry use on frozen sections. Compared to wide local excision, MMS treatment demonstrates similar or improved outcomes for local tumor recurrence, melanoma-specific survival, and overall survival at long-term follow-up. Tumor upstaging risk is low, and if present, alteration to clinical management is minimal. Discussion of SLNB for eligible head and neck IM cases should be done prior to MMS. Though challenging, successful multidisciplinary coordination of SLNB with MMS has been demonstrated. Herein, we provide a detailed clinical review of evidence for MMS treatment of cutaneous melanoma and offer recommendations to address current controversies surrounding the evolving paradigm of surgical management for both MIS and invasive melanoma (IM).

    虽然单个生物仿制药的价值是显而易见的,除了生物仿制药和发起人之间的成本节约之外,人们对生物仿制药组合的价值知之甚少。利益相关者可以考虑制造商的生物仿制药组合的价值,特别是在谈判基于投资组合的合同或其他返利计划时。然而,对其他类型的价值知之甚少,除了经济利益,决策者认为,与没有生物类似药的制造商相比,有生物类似药的制造商。这篇综合文献综述的目的是描述一个由主题组成的概念框架,这些主题可能有助于定义生物仿制药组合的价值。
    使用ExcerptaMedica数据库(Embase)和在线医学文献分析和检索系统(MEDLINE)进行了综合文献综述。搜索引擎的灰色文献检索,未在Embase或MEDLINE中索引的期刊,医疗保健支付者,卫生技术评估机构,价值框架,和非制药工业类似物也进行了。合格的研究报告了生物类似药组合在利益相关者决策中的价值。除了文学,从临床经验和观察中获得了见解。
    没有确定调查生物仿制药组合价值的研究;然而,确定了几个主题,这些主题可能有助于定义生物仿制药组合的价值:制造;采购,库存,和存储;管理;教育;和交易成本。确定了几种非制药行业类似物:产品线长度和单个供应商与多个供应商的采购。通过其他来源确定了几个主题:科学可信度和研究。基于这些主题,我们建立了生物类似药组合价值的概念框架。
    据我们所知,这是第一项系统评估和建立生物仿制药组合价值框架的研究。可以测试此处描述的概念框架,以量化与生物仿制药组合相关的临床和经济价值。

    UNASSIGNED: While the value of individual biosimilars is evident, little is known about the value of a biosimilar portfolio beyond the cost savings between biosimilars and originators. Stakeholders may consider the value of a manufacturer\'s biosimilar portfolio, especially when negotiating portfolio-based contracts or other rebate programs. However, little is known about what other types of value, in addition to financial benefits, decision-makers perceive regarding a manufacturer with a biosimilar portfolio compared to those without one. The objective of this integrative literature review was to describe a conceptual framework consisting of themes that may help define the value of a biosimilar portfolio.
    UNASSIGNED: An integrative literature review was conducted using Excerpta Medica Database (Embase) and Medical Literature Analysis and Retrieval System Online (MEDLINE). Grey literature searches of search engines, journals not indexed in Embase or MEDLINE, healthcare payers, health technology assessment bodies, value frameworks, and non-pharmaceutical industry analogs were also conducted. Eligible studies reported on the value of a biosimilar portfolio in decision-making by stakeholders. Apart from the literature, insights were gained from clinical experience and observation.
    UNASSIGNED: No studies investigating biosimilar portfolio value were identified; however, several themes were identified that may help define the value of a biosimilar portfolio: Manufacturing; procurement, inventory, and storage; administration; education; and transaction costs. Several non-pharmaceutical industry analogs were identified: Product line length and single-supplier versus multiple-supplier procurement. Several themes were identified through other sources: Science credibility and research. Based on these themes, we developed a conceptual framework for biosimilar portfolio value.
    UNASSIGNED: To our knowledge, this is the first study to systematically assess and create a framework for biosimilar portfolio value. The conceptual framework described here could be tested to quantify the clinical and economic value associated with a biosimilar portfolio.
    Though the value of single biosimilars is evident, little is known about the value of a biosimilar portfolio beyond the cost savings incurred between biosimilars and originators.We identified seven themes that may help to define the value of a biosimilar portfolio: Manufacturing; procurement, inventory, and storage; administration; education; transaction costs; science credibility; and research.These themes may be integrated into a conceptual framework that may form a basis to help quantify the clinical and economic benefit of a biosimilar portfolio to stakeholders.

    由于肿瘤学领域越来越关注以患者为中心的护理,以及对医疗保健系统可持续性的更大压力,关于什么是价值的讨论重新出现。政策制定者寻求提高患者价值观,然而,为所有价值观提供资金是不可持续的。
    我们从科学文献中收集现有证据,并反思价值的概念,可能在报销决定中纳入广泛的价值,以及增加肿瘤护理价值的替代策略。
    我们指出,价值拥有许多不同的方面。对于报销决定,我们认为,由于需要有效的资源分配,将所有患者价值纳入其中是不可行的。我们认为,我们应该将价值辩论从患者的个人角度转移到为整个癌症人群创造价值。我们解决的不同策略是:1)共同决策,2)生物标志物和分子诊断,3)适当的评价,支付和使用药物,4)支持性护理,5)癌症预防和筛查,6)监测后期效果,7)集中护理和肿瘤网络,和8)共病管理。支持这些战略的重要前提是战略规划,一致的癌症政策和数据可用性。
    UNASSIGNED: As a result of an increasing focus on patient-centered care within oncology and more pressure on the sustainability of health-care systems, the discussion on what exactly constitutes value re-appears. Policymakers seek to improve patient values; however, funding all values is not sustainable.
    UNASSIGNED: We collect available evidence from scientific literature and reflect on the concept of value, the possible incorporation of a wide spectrum of values in reimbursement decisions, and alternative strategies to increase value in oncological care.
    UNASSIGNED: We state that value holds many different aspects. For reimbursement decisions, we argue that it is simply not feasible to incorporate all patient values because of the need for efficient resource allocation. We argue that we should shift the value debate from the individual perspective of patients to creating value for the cancer population at large. The different strategies we address are as follows: (1) shared decision-making; (2) biomarkers and molecular diagnostics; (3) appropriate evaluation, payment and use of drugs; (4) supportive care; (5) cancer prevention and screening; (6) monitoring late effect; (7) concentration of care and oncological networking; and (8) management of comorbidities. Important preconditions to support these strategies are strategic planning, consistent cancer policies and data availability.

    关于基于价值的支付模式提高护理质量和确保更有效结果的潜力的证据是有限的和混合的。我们的目标是确定增强或抑制设计的因素,实施,并通过系统的文献综述对这些模型进行了应用。我们使用了PRISMA指南。根据理论框架,将促进因素和抑制因素分为子类别。我们包括143种出版物,每个报告多个因素。目标和战略的调解人,如现实/可实现的目标,在56项研究中报道。关于专用时间和资源的障碍(例如,在25项研究中报道了过多的时间来改善表现)。网络内就目标和战略达成共识,信任,良好的协调至关重要。医护人员需要保持积极性,消息灵通,并积极参与。此外,利益相关者应该管理关于预期何时实现结果的期望。
    Evidence on the potential for value-based payment models to improve quality of care and ensure more efficient outcomes is limited and mixed. We aim to identify the factors that enhance or inhibit the design, implementation, and application of these models through a systematic literature review. We used the PRISMA guidelines. The facilitating and inhibiting factors were divided into subcategories according to a theoretical framework. We included 143 publications, each reporting multiple factors. Facilitators on objectives and strategies, such as realistic/achievable targets, are reported in 56 studies. Barriers regarding dedicated time and resources (e.g., an excessive amount of time for improvements to manifest) are reported in 25 studies. Consensus within the network regarding objectives and strategies, trust, and good coordination is essential. Health care staff needs to be kept motivated, well-informed, and actively involved. In addition, stakeholders should manage expectations regarding when results are expected to be achieved.

    目的:了解白内障手术的可持续性方法及其风险和益处临床意义:在美国,医疗保健约占温室气体(GHG)的8.5%,白内障手术是最常见的手术之一。眼科医生可以为减少温室气体排放做出贡献,这导致了从创伤到食物不稳定等健康问题的稳步增加。
    方法:我们进行了文献综述,以确定可持续性干预措施的益处和风险。然后,我们将这些干预措施组织成决策树,供个别外科医生使用。
    结果:已确定的可持续性干预措施属于宣传和教育领域,制药,process,供应和浪费。现有文献表明某些干预措施可能是安全的,成本效益高,和环保。这些措施包括在手术后向患者分发药物,多剂量适当的药物,培训员工正确分类医疗废物,减少手术过程中使用的用品数量,并在临床适当的情况下实施立即序贯双侧白内障手术。文献缺乏一些干预措施的益处或风险,例如,将特定的一次性用品切换到可再使用产品,或实施轮毂式剧院设置。许多宣传和教育干预措施缺乏专门针对眼科的文献,但风险可能很小。
    结论:眼科医生可以采用各种安全有效的方法来减少或消除与白内障手术相关的危险温室气体排放。
    OBJECTIVE: Understanding approaches to sustainability in cataract surgery and their risks and benefits.
    CONCLUSIONS: In the United States, health care is responsible for approximately 8.5% of greenhouse gas (GHG), and cataract surgery is one of the most commonly performed surgical procedures. Ophthalmologists can contribute to reducing GHG emissions, which lead to a steadily increasing list of health concerns ranging from trauma to food instability.
    METHODS: We conducted a literature review to identify the benefits and risks of sustainability interventions. We then organized these interventions into a decision tree for use by individual surgeons.
    RESULTS: Identified sustainability interventions fall into the domains of advocacy and education, pharmaceuticals, process, and supplies and waste. Existing literature shows certain interventions may be safe, cost-effective, and environmentally friendly. These include dispensing medications at home to patients after surgery, multi-dosing appropriate medications, training staff to properly sort medical waste, reducing the number of supplies used during surgery, and implementing immediate sequential bilateral cataract surgery where clinically appropriate. The literature was lacking on the benefits or risks for some interventions, such as switching specific single-use supplies to reusables or implementing a hub-and-spoke-style operating room setup. Many of the advocacy and education interventions have inadequate literature specific to ophthalmology but are likely to have minimal risks.
    CONCLUSIONS: Ophthalmologists can engage in a variety of safe and effective approaches to reduce or eliminate dangerous GHG emissions associated with cataract surgery.
    BACKGROUND: Proprietary or commercial disclosure may be found after the references.

    SARS-CoV-2疫苗接种一直是预防COVID-19的最有效工具,显著减少了全世界的死亡和住院。疫苗接种在控制COVID-19大流行方面发挥了巨大作用,即使疫苗的不公平分配仍然使几个国家脆弱。因此,在全球范围内组织大规模疫苗接种运动是遏制病毒传播的优先事项。这项系统评价的目的是评估COVID-19疫苗接种运动是否与不接种疫苗相比具有成本效益。在WHOCOVID-19全球文献数据库中进行了系统的文献检索,PubMed,WebofScience,Embase,和Scopus从2020年到2022年。评估COVID-19疫苗接种运动成本效益的研究被认为是合格的。采用“德拉蒙德检查表”进行质量评估。通过“优势排名矩阵工具”对研究进行了综合。总的来说,考虑了10项研究。他们每个人都认为COVID-19疫苗接种具有成本效益,疫苗接种运动被认为是应对卫生紧急情况的可持续公共卫生方法。需要为大规模疫苗接种提供经济评估数据,以支持决策者做出基于价值和基于证据的决策,以确保公平获得疫苗接种并减轻全球COVID-19负担。
    SARS-CoV-2 vaccination has been the most effective tool to prevent COVID-19, significantly reducing deaths and hospitalizations worldwide. Vaccination has played a huge role in bringing the COVID-19 pandemic under control, even as the inequitable distribution of vaccines still leaves several countries vulnerable. Therefore, organizing a mass vaccination campaign on a global scale is a priority to contain the virus spread. The aim of this systematic review was to assess whether COVID-19 vaccination campaigns are cost-effective with respect to no vaccination. A systematic literature search was conducted in the WHO COVID-19 Global literature database, PubMed, Web of Science, Embase, and Scopus from 2020 to 2022. Studies assessing the COVID-19 vaccination campaign cost-effectiveness over no vaccination were deemed eligible. The \"Drummond\'s checklist\" was adopted for quality assessment. A synthesis of the studies was performed through the \"dominance ranking matrix tool\". Overall, 10 studies were considered. COVID-19 vaccination was deemed cost-effective in each of them, and vaccination campaigns were found to be sustainable public health approaches to fight the health emergency. Providing economic evaluation data for mass vaccination is needed to support decision makers to make value-based and evidence-based decisions to ensure equitable access to vaccination and reduce the COVID-19 burden worldwide.

    背景:对阿尔茨海默病(AD)患者的重要概念与AD临床研究中常用的临床结果评估(COAs)之间的关系的了解有限。“最重要的是什么”(WMM)研究系列的第1和第2阶段确定并定量确认了42项与治疗相关的结果,这些结果对受AD影响的人很重要。
    方法:我们将被评为“非常重要”或更高的WMM概念与AD研究中常用的COA中包含的项目进行了比较。
    结果:20个用于评估体征的COA,症状,并选择了整个AD频谱的影响进行审查。在这20个COA中,只有5个反映了12个或更多的WMM概念[阿尔茨海默病综合评定量表(iADRS),阿尔茨海默病合作研究-日常生活活动量表(ADCS-ADL),阿尔茨海默病合作研究-日常生活活动量表-轻度认知障碍(ADCS-ADL-MCI),阿尔茨海默病综合评分(ADCOMS),和临床痴呆评级;临床痴呆评级-方框和(CDR/CDR-SB)]。在WMM研究中被确定为重要且有意义的AD的多种症状和影响最多只能间接映射到20个最广泛使用的COA中的7个。
    结论:虽然许多在AD中经常使用的COA捕获了一些被认为对AD人群及其护理伙伴重要的概念,任何单一的措施和受AD影响的人重要的概念之间的重叠是有限的。最高的单一匹配COA反映了不到一半(45%)的WMM概念。使用多个COA扩展了有意义的概念的覆盖范围。未来的研究应在进一步确认WMM项目生态有效性的基础上,探索计划用于AD试验的ADCOA的内容有效性。这项研究应告知开发和使用捕获WMM项目的核心结果集,并选择或开发新的伴随工具,以充分展示跨越WMM的临床有意义的结果。
    BACKGROUND: Insight into the relationship between concepts that matter to the people affected by Alzheimer\'s disease (AD) and the clinical outcome assessments (COAs) commonly used in AD clinical studies is limited. Phases 1 and 2 of the What Matters Most (WMM) study series identified and quantitatively confirmed 42 treatment-related outcomes that are important to people affected by AD.
    METHODS: We compared WMM concepts rated as \"very important\" or higher to items included in COAs used commonly in AD studies.
    RESULTS: Twenty COAs designed to assess signs, symptoms, and impacts across the spectrum of AD were selected for review. Among these 20 COAs, only 5 reflected 12 or more WMM concepts [Integrated Alzheimer\'s Disease Rating Scale (iADRS), Alzheimer\'s Disease Cooperative Study-Activities of Daily Living Inventory (ADCS-ADL), Alzheimer\'s Disease Cooperative Study-Activities of Daily Living Inventory-Mild Cognitive Impairment (ADCS-ADL-MCI), Alzheimer\'s Disease Composite Scores (ADCOMS), and Clinical Dementia Rating; Clinical Dementia Rating-Sum of Boxes (CDR/CDR-SB)]. Multiple symptoms and impacts of AD identified as important and meaningful in the WMM studies map only indirectly at best to 7 of the 20 most widely used COAs.
    CONCLUSIONS: While many frequently used COAs in AD capture some concepts identified as important to AD populations and their care partners, overlap between any single measure and the concepts that matter to people affected by AD is limited. The highest singly matched COA reflects fewer than half (45%) of WMM concepts. Use of multiple COAs expands coverage of meaningful concepts. Future research should explore the content validity of AD COAs planned for AD trials based on further confirmation of the ecological validity of the WMM items. This research should inform development and use of core outcome sets that capture WMM items and selection or development of new companion tools to fully demonstrate clinically meaningful outcomes spanning WMM.
