Welcome to the webpage of the NIHR ESGs Best Practice Working Group on Living Evidence Synthesis (LES) -- a UK-based community of practice (CoP) for sharing best practices in the planning, conduct, and dissemination of LES among National Institute for Health Research (NIHR) Evidence Synthesis Groups (ESGs). This working group / CoP ('the Group') has been convened by the specialised LES group (BUcKLES) on behalf of all UK-based ESGs, currently comprising: nine evidence synthesis groups, three specialised screening evidence synthesis groups, and the specialised LES group itself.
The Group will:
- Provide a forum for discussion about LES methods, tools, and workflows;
- Facilitate capacity building for the further development, judicious application, and rigorous evaluation of LES methods, tools, and workflows; and
- Develop agreed criteria and guidance for the use and application of LES to inform policy, practice, and research, including consideration of topic suitability.
See our living 'Terms of Reference' document for further information.
