Dear HIFA colleagues,
In a previous message (above) I wrote: 'Our Lancet paper in 2004 was, to our knowledge, the first to describe what is now known as the global evidence ecosystem.'
https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(04)16681-6/fulltext
This was based on a question I put to AI (Copilot): "Tell me about the evolution of the concept of the global evidence ecosystem"
It caught my attention when I read: 'Your own 2004 paper (“Can we achieve health information for all by 2015?”) was one of the first to describe the entire evidence-to-practice pipeline as a system — involving researchers, policymakers, publishers, librarians, indexers, and systematic reviewers — and to diagnose it as poorly understood, unmanaged, and under-resourced. This was an early articulation of what is now called the global evidence ecosystem.'
I have looked into this and there are now several representations, for example:
1. HIFA global evidence ecosystem: www.hifa.org/ecosystem
2. The JBI model of evidence-based healthcare: https://jbi.global/jbi-model-of-EBHC
3. The knowledge-to-action framework: https://pmc.ncbi.nlm.nih.gov/articles/PMC2717660/figure/f1-1810165/
I would be interested to learn more about different models. The knowledge-to-action framework, for example, is based on a review of more than 30 previous models, but unfortunately this is behind a paywall so ironically most of us cannot read it.
Each of the above three models may not be exactly analogous as they may have different applications. The aim of the HIFA model is to make a simple point: that the availability and use of reliable healthcare inforamtion is dependent on the integrity of a global system with six basic components. The JBI model depicts evidence-based healthcare as decision-making that considers the feasibility, appropriateness, meaningfulness and effectiveness of healthcare practices. And the knowledge-to-action framework is intended as a practical aid for knowledge translation.
I look forward to your comments and suggestions.
Best wishes, Neil
