Living Evidence (including living systematic reviews and living guideline recommendations) is a prospective approach and active processes that use continuous evidence surveillance and rapid response pathways to incorporate new relevant evidence as it becomes available.

Practically, this means that living systematic reviews and guidelines:

  • Are underpinned by continual, active monitoring of the evidence (i.e. monthly searches)

  • Rapidly incorporating new important evidence (meaning data, studies or information) that is identified

  • Are supported by up-to-date communication about the status of the review or guideline, and any new evidence being incorporated in the recommendation/s.

In addition to continuous updating, Living Evidence aims to improve the quality, utility and value of evidence synthesis activities by broadening the range of health-related data that can be included in evidence reviews (eg. data from studies other than randomised controlled trials, real-world health data and data from clinical study reports) and using structured (semantic) data to improve data discoverability and re-use.
