About this Research Topic

Background

One key area of increased focus and importance in the Regulatory Science Strategy for 2025 published by the European Medicines Agency is the improved transparency of treatment decision-making at macro and micro (patient) levels, including the communication and management of uncertainties. Uncertainty can be defined as "lacking complete knowledge or understanding of a given situation". Uncertainties can be attributed to lacking clinical or patient data and result in uncertainties on behalf of decision-makers who need to make decisions based on these data. In the context of regulatory decision-making, uncertainty may translate into difficulties in evaluating the quality, safety, efficacy, and overall benefit-risk balance of a medicinal product for a given patient population. Uncertainties in drug development prior to the approval and reimbursement of medicines will also result in uncertainties in Health Technology Assessment, payer, patient, and healthcare provider decision-making. Stakeholders in drug development and evaluation (commercial and non-commercial developers, regulators, clinicians, academics, HTA) are keen to know how they could better manage and communicate uncertainties in their various decision-making contexts so as to improve their decision-making processes and allow for increased transparency towards the public, and especially patients.

This topic is dedicated to research aiming to address the complex question of how to manage and communicate uncertainties in medicines development, evaluation, and use. Currently, there is no structured approach for defining, categorizing, managing, and communicating uncertainties at various decision-making levels in drug development, evaluation, and use. Such decisions include the identification of unmet needs, the allocation of resources in drug development, the selection of clinical trial endpoints and outcomes, the selection of patient-reported outcome measures, regulatory evaluation, and the assessment of benefits and risks, health technology assessment, reimbursement, and clinical treatment decision-making. In the context of drug regulation, uncertainty management and communication tools (such as templates, guidance, checklists) are missing for assessors and developers. Topics where uncertainties revolve around include the type of (long-term) treatment effects, the appropriateness of clinical trial endpoints, the size of treatment effects and their relevance, patient-reported outcomes, etc. These represent policy and research foci receiving much attention from regulators, drug developers, scientists, clinicians, and patients, where evidence-based insights and solutions surrounding these would be highly welcomed.

Topics of interest are related to the (optimized) conceptualization, definition, categorization, management, and communication of uncertainties in healthcare decision-making spanning across the treatment lifecycle. We would like contributors to address uncertainties and evidence gaps in the clinical trial and real-world context, as well as in regulatory evaluation, market access, health technology assessment, and treatment use (including by patients and clinicians). Authors can also focus on how uncertainties and mitigation strategies are discussed and approached at the policy-making level. Authors are invited to address strategies for addressing communication and evidence gaps, such as real-world evidence. Strategies for improved transparency of uncertainties are also highly welcomed, including at the regulatory-HTA interface (parallel scientific advice) and at the patient-physician level via patient decision aids. Of interest are uncertainties regarding unmet (medical) needs, (long-term) treatment effects, appropriateness of endpoints, treatment strategies, and ways to address these. Different types of articles are welcomed, including umbrella or systematic reviews, original research (e.g., qualitative research, quantitative (survey) research), and perspective articles.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?
