Regularly updated, BMJ Best Practice draws on the latest evidence-based research

Evidence Matters

BMJ has been championing EBM since David Sackett, in his famous 1996 editorial (Evidence based medicine: what it is and what it isn’t) set out the tenets of the movement – as an approach that “integrates the best external evidence with individual clinical expertise and patients’ choice”.

Being evidence-based is embedded into BMJ’s company culture and is one of our five company values. BMJ is a founding member of the UK GRADE Network, and the international conference on evidence-based healthcare, Evidence Live. Today, the BMJ Knowledge Center’s team of in-house information specialists searches the literature for high-quality new and updated international guidelines and systematic reviews, as well as tailoring bespoke searches to support BMJ Best Practice topic updates.

Over recent years, the BMJ Knowledge Center team has conducted extensive research with healthcare professionals worldwide to understand how you use evidence to support your work. You told us you want a single source of evidence-based answers to important real-world clinical questions so you can make evidence-informed decisions in your clinical work. You need current, trustworthy evidence delivered quickly and succinctly at the point-of-care. You want a simple presentation, transparency around evidence quality, and the ability to delve deeper to see further detail. This is precisely what we deliver.

Components of EBM

BMJ Best Practice processes support all three components of EBM: best available evidence, clinical expertise, and patient values and preferences.

Best available evidence

  • Updates to BMJ Best Practice topics incorporate new best available evidence.

Clinical expertise

  • Our in-house evidence and editorial teams collaborate with over 1,600 international expert contributors and over 2,500 peer reviewers to ensure that BMJ Best Practice provides access to the most clinically relevant information possible.

Patient values and preferences

  • BMJ Best Practice condition topics have a ‘Patient discussion’ section, prompting the healthcare professional on patients’ information needs
  • Best Practice includes over 500 patient leaflets to make shared decision-making easier.  Leaflets are
    • Concise and clear, written by specialist editors, and reflect the evidence-based clinical information in BMJ Best Practice
    • Reviewed by patients
    • Linked to relevant topics, allowing them to be browsed or searched for.

Evidence processes

Our robust evidence processes include:

  1. Routine scheduled topic updates
  2. Surveillance for new practice-changing evidence and for drug alerts
  3. Quality assurance.

Routine scheduled topic updates

We prioritize our most popular topics and those with rapid changes in research for more frequent routine updates. Where there is an exceptional need for important changes to be made particularly rapidly, such as during the Covid-19 pandemic, updates may occur every week.

Updates for high-priority topics start with a medical database literature search by our experienced information specialists, focussing on relevant systematic reviews and guidelines. Section editors, trained in critical appraisal, appraise the evidence and work with expert contributors to select new evidence for inclusion and to make changes to update the existing topic.

Our ongoing evidence surveillance process

In addition, topic updates may be triggered at any time by evidence retrieved from our ongoing surveillance process. This includes:

  • Surveillance for high quality new and updated international guidelines, policy statements, and potentially practice-changing systematic reviews and randomized controlled trials
  • Prompt evaluation of new evidence by our specialist section editors
  • Continuous scanning and triaging of drug alerts by our inhouse pharmacists (see below)
  • Monitoring and triaging of user/customer feedback by our specialist section editors.

Drug surveillance

Our in-house pharmacists review drug alerts released by international drug regulatory agencies daily. This includes the Food and Drug Administration, European Medicines Agency, UK-based Medicines and Healthcare Products Regulatory Agency, and other useful secondary sources. Important practice-changing alerts (e.g., drug withdrawals, drug dose updates, new contraindications) are prioritized for incorporation into relevant content. All drug doses in BMJ Best Practice are reviewed and approved by qualified, registered pharmacists with extensive experience in pharmacy practice.

Quality assurance

All new BMJ Best Practice topics have an external peer review by at least two leading international experts and practicing clinicians.

All BMJ Best Practice topic content updates have internal peer review and sign-off by our in-house pharmacists and senior content editors.

Extensive customer research shows that you value the rapid delivery of practice-changing evidence that BMJ Best Practice offers at the point of care. Updates are prioritized as follows:

  1. Drug changes or withdrawals that may affect patient safety
  2. Evidence that changes practice
  3. Evidence that confirms current practice.
