Evidence-informed health policy, practice and decision making underpins public health action. The Observatory Evidence Service supports this by producing systematic reviews, evidence maps and rapid summaries.

Our methods are transparent and reproducible and we give the quality of the research included due consideration. We use evidence from a wide variety of sources that adopt different research methodologies to develop outputs that are fit-for-purpose. We also provide specialist support and advice to colleagues in Public Health Wales who are involved in evidence projects.

The 'Current Awareness Bulletin', a monthly listing of reports, official publications, information resources and more can be found here.



During the pandemic we have been working with others to develop some evidence summaries that answer some important questions relating to COVID-19 and public health strategies. 

We produced a monthly COVID-19 current awareness bulletin during 2020 and 2021 which can be accessed here. This has now been incorporated into our usual current awareness bulletin which can be found on the Evidence homepage.
