2025 CAMPAIGN:
COLLABORATIVE KNOWLEDGE COMMUNICATION
#WorldEBHCDay
The science of communication is evolving, with insights from storytelling, digital media, open science, and knowledge translation transforming how evidence can—and must—be shared to inform decision-making.
By focusing on science communication, the World EBHC Day 2025 campaign aims to foster discussion and contribute to global discourse on the human, cultural, technological and political dynamics that shape how evidence travels—and transforms lives.
We invite the global evidence community to share your innovations, experiences, challenges, lessons learned and promising failures around inclusive, participatory science communication by submitting a blog, vlog or hosting an event.
WORLD EBHC DAY ENGAGEMENT & REACH
WHERE IT ALL BEGAN
World Evidence-Based Healthcare Day was founded in 2020 by JBI with a view to raising awareness of the need for better evidence to inform health policy, practice and decision making to improve health outcomes globally.
FROM EVIDENCE TO IMPACT
In its inaugural year, the World EBHC Day campaign Evidence to Impact asked the global evidence community to reflect and share experiences of using evidence to generate impact in healthcare globally. The 35 impact stories that were shared were a powerful reminder of the role we all have in ensuring trustworthy evidence is used to inform decision making.

THE ROLE OF EVIDENCE IN AN INFODEMIC
Building on the collective wisdom of using evidence to generate impact in 2020, the 2021 World EBHC Day campaign focused on the role of evidence in an infodemic. Guided by infodemiologist Gunther Eysenbach’s work on infodemic management, and in support of the World Health Organization’s campaign to manage the COVID-19 infodemic, authors of blogs and hosts of events for World EBHC Day 2021 took on the role of Evidence Ambassadors to promote access to evidence-informed and trustworthy information, while helping to combat misinformation.
The strong emergent theme from the 37 blogs published and 30+ events held on 20 October 2021 was the role and importance of partnership. Evidence Ambassadors highlighted the immense importance of interdisciplinary collaboration and multisectoral action between those who generate reliable, trustworthy evidence and those who have the power and influence to effectively disseminate it, implement it and use it. Stories of cooperation and collaboration between key stakeholders in the evidence ecosystem to develop multifaceted approaches and pragmatic solutions for infodemic management were shared widely.

Partnerships for Purpose
The campaign for World EBHC Day, Partnerships for Purpose, followed the strong emergent theme of partnerships from the 2021 campaign blogs, and reflects the huge increase in global partnerships as a result of the COVID-19 pandemic.
The COVID-19 pandemic highlighted the importance of evidence-based healthcare and the need for partnerships in developing rapid evidence-informed responses, streamlining global efforts, reducing research waste, and ensuring the best-available evidence is accessible, transparent and understood. While many partnerships pre-existed the pandemic, since 2020 there has been an extraordinary increase in new and innovative partnerships and collaboration between regulators, governments, scientists and researchers, healthcare providers, tech giants and consumer groups. Through 41 blogs and 30 vlogs, we shared our experiences and lessons learned from partnerships within and across the global evidence ecosystem whose purpose was to bridge research, policy and practice, and realise the potential of evidence-based healthcare.

The headlining event in 2022 was the webinar hosted by the organising partners, ‘Equity in global health partnerships’. The discussion and engagement generated from this webinar led to the campaign for 2023, Equity 2023 World EBHC Day campaign, Evidence and Global Health Equity.
EVIDENCE AND HEALTH EQUITY
The campaign for World EBHC Day 2023 focused on ‘Evidence and Global Health Equity’ and aimed to examine how the global evidence community can foster and embed equity within and across evidence ecosystems to advance global health equity.
The theme for the 2023 campaign was in response to ‘equity’ being one of the themes from the blogs submitted for the World EBHC Day 23022 Campaign, and in 2023 we reached the mid-way point for the 2030 United Nations Sustainable Development Goals (SDGs) and a global commitment to ‘leave no one behind’. However, the global crises of humanitarian disasters, climate change and health pandemics are all impeding progress and exacerbating global health inequities, highlighting the urgency to strengthen local and global evidence ecosystems to address societal challenges.
Health inequities are the unfair, unjust and avoidable differences in health caused by how power, resources, and money are distributed in society. According to the WHO “achieving an impact on global health and equity is the ultimate aim of better use of research evidence in health decision-making.” However, the ways in which we commission, fund, produce, synthesise, disseminate, translate and use evidence to inform health policy and practice can either worsen existing health inequities or help to address and overcome health equity challenges. The 2023 campaign was a call to action by the global evidence community to share their experiences to help foster and embed equity-centred evidence-informed decision making and strengthen evidence ecosystems to advance global health equity.

Almost 100 individuals and organisations supported World Evidence-Based Healthcare Day 2023 as Evidence Ambassadors. The World EBHC Day organising partners were joined by Campaign Partners: 3ie (International Initiative for Impact Evaluation); University of Global Health Equity, eBASE Africa, The George Institute for Global Health, and Healthcare Information for All.
The headlining event in 2023 was the webinar, ‘An introduction to evidence and global health equity', hosted by the organising partners and sponsored by Wolters Kluwer Health. While acknowledging that there are several complexities that impact health equity, the webinar served as a forum for introductory discussion. A panel shared their stories, and how equity can be fostered and embedded within the evidence ecosystem.
