How can we all best use evidence?
For more information, visit our dedicated microsite.
Over the past few years, questions have been raised in both the general and scientific media about the evidence underlying decisions about treatment options, for example the use of statins to prevent heart disease and stroke, of Tamiflu to treat influenza and of hormone replacement therapy to treat the symptoms of the menopause. The validity of the different ways of collecting and analysing evidence has been part of this debate, as have broader discussions of issues such as medicalisation (or the reliance on prescribing drugs over lifestyle changes) and conflicts of interest in the way that evidence collection is funded and/or analysed.
The Academy’s report, ‘Enhancing the use of scientific evidence to judge the potential benefits and harms of medicines’, explores these issues further. It concludes that scientific evidence should be at the heart of decisions about the use of medicines, as it is open to check and challenge. To enable this, the report calls for improvements to:
- The generation of scientific evidence to ensure it is robust, reliable and relevant to patients.
- The trustworthiness of scientific evidence so that information is disclosed in an accessible, assessable, and usable manner.
- The communication of evidence to ensure it is presented in a clear, accurate and actionable way.
Making progress on these fronts will require a collective effort from a wide range of stakeholders across the biomedical community.
The report, and its associated annexes and case studies, are available to download on the right hand side of this page. A summary of the report’s recommendations is provided in ‘The report’s recommendations in brief’ tab. A summary of the report and questions that patients could consider asking their doctor during consultations are also available to download on the right hand side of this page.
We would welcome your comments on the report (please send your feedback to email@example.com).
Evidence feeding into the project
The report brings together a series of sub-projects that considered elements relating to:
- The strengths and limitations of different sources of evidence used to evaluate benefits and harms of medicines.
- The ways in which conflicts of interest impact on the validity (or perception of validity) of evidence.
- The communication of evidence to support discussion and decision-making.
- The perceptions and perspectives of society on scientific evidence (including in the context of shared decision making between patients and their clinicians).
Evidence that has contributed to this report, including workshop reports from the sub-projects are available in the evidence repository for this project.
Financial contributions towards the project
Arthritis Research UK, the British Heart Foundation (through a Strategic Funding Award), the British Pharmacological Society, the British Society for Immunology, the Medical Research Council, the Naji Foundation and the National Institute of Health Research Health Technology Assessment Programme kindly provided financial contributions towards this work. Funding from a core grant
from the Department for Business, Energy and Industrial Strategy to the Academy was also used to support this project. This was an independent project that had the support of the Chief Medical Officer. Funders did not approve the conclusions and recommendations and were not sent a draft of the report for approval.
Based on a forthcoming editorial in the British Journal of General Practice.
Ensuring evidence is robust and relevant
- Patients, carers and the public should be more involved in the direction, delivery and dissemination of clinical research.
- All those involved in clinical research and all healthcare professionals (at all career stages) should receive a grounding in the research methods and statistics used to evaluate the benefits and harms of treatment options.
- The importance of robust, reproducible and reliable research should be recognised and emphasised.
- New sources of evidence should be used to best advantage, with more emphasis on finding ways to extract and share useful data from different sources.
Ensuring evidence is trustworthy
- Research findings and data should be published in as open, balanced and complete way as possible.
- Any interests should be routinely declared and any potential conflicts of interest managed in an open and transparent way.
- Academia-industry relationships should be managed under a set of clear guidelines.
Ensuring evidence is communicated and used effectively
- Patient information leaflets should be improved to give a clear and balanced appraisal of the potential benefits and harms of treatment options.
- NHS Choices should become a central repository of clear, balanced and up-to-date evidence on healthcare options.
- Improved reporting of scientific evidence in the media should be encouraged, with a role for academic establishments and researchers in ensuring their research is accurately reflected.
- Increased support for shared decision-making should be provided, including adequate resourcing of primary care services and the provision of decision aids through NHS Choices.
- Continued dialogue and engagement with patients and the public is needed to monitor the impact of these recommendations and ensure responsiveness to changing public needs in healthcare.
This workstream examined the evaluation of scientific evidence for medicinal products and how this evidence is interpreted and assimilated by different groups (including, but not limited to, patients, the public, healthcare professionals, researchers and communicators). It aimed to better align evidence generation with user expectations, and facilitate decision-making about therapeutic options. In doing so, the workstream explored:
- How different groups’ perspectives and perceptions affect their evaluation of evidence. This formed the basis of dialogue activities throughout the project.
- The strengths and limitations of results and conclusions that originate from different study types or data sources to evaluate the benefits and harms of medicinal products. This was examined by a sub-group study launched in summer 2015.
- How interests (including, but not limited to, different models and sources of funding) impact on the validity, or the perception of validity, of evidence. This was informed by a workshop in November 2015.
- How to effectively communicate research findings to improve the understanding of evidence about the benefits and harms of medicinal products. This was informed by a workshop in June 2016.
The overarching report embraced and informed decision-making about medicines, and developed a list of practical recommendations relating to the interpretation, weighting, and communication of evidence. These aimed to enable a wide range of groups (as described above) to better consider the benefits and harms of medicinal products. The report drew on examples of dilemmas in current therapeutic practice, but did not seek to address all such areas of contention, nor to replicate the work performed by the Medicines and Healthcare products Regulatory Agency and the National Institute of Health and Care Excellence. The remit of this project required expertise from outside of the Academy, and we therefore engaged widely via a call for evidence, workshops, and further dialogue with a broad range of stakeholders.
