Strengthening the public health evidence ecosystem

Infectious disease prevention and control decisions can significantly impact individuals, populations and society. To ensure that public health policies and interventions are sound, decisions must be based on the best available evidence, be scientifically credible, operational, and relevant to the context they are applied to. 

While public health agencies are not always the ultimate policy and decision-makers, they play a vital role in enabling informed, timely and effective decisions supported by scientific-based evidence. 

'The best available evidence is a cornerstone of public health scientific advice, especially now, as the world faces an unprecedented surge in mis- and disinformation. A strong public health evidence ecosystem, integrating multiple streams and types of evidence, is essential for supporting transparent and sound public health decision-making, and for strengthening trust in science and science-based public health institutions across Europe.' - Piotr Kramarz, ECDC Chief Scientist

ECDC plays a crucial role in the public health evidence ecosystem by 

  • coordinating and collaborating with Member States and other partners
  • contributing to evidence generation through robust surveillance and applied research and analysis and to evidence synthesis by critically and systematically combining and interpreting findings from different evidence sources
  • translating this evidence into clear guidance, risk assessments and public health recommendations
  • presenting and communicating findings and recommendations in a way that resonates with decision-makers and the public, ensuring clarity, relevance and accessibility.

Evidence-based Public Health initiative

ECDC’s Evidence-Based Public Health (EBPH) initiative aims to strengthen the systematic use of evidence in public health decision-making. 

An independent Methodological Advisory Group supports the initiative, being composed of external experts, including methodologists and infectious disease and public health experts. Its tasks include 

  • offering strategic advice to ECDC
  • identifying priority areas
  • helping raise awareness through public health networks
  • ensuring that ECDC’s EBPH initiative meets the needs of the agency and national stakeholders.

The initiative develops user-friendly methodological guidance and tools to support ECDC staff and other public health professionals in applying evidence-based methods and approaches. These materials are developed by a group of four institutions: the Ludwigs- Maximilians- University of Munich, Cochrane Germany, Cochrane Austria and the Norwegian Institute of Public Health. The key priority areas for 2025 are the following:

  • Integration of different evidence types and streams
  • Elicitation and integration of expert knowledge
  • Rapid and ultra-rapid evidence-based public health advice
