Trust and transparency in research Why do patients enrol in a clinical trial?
To benefit from new agents To assist and support research To improve health care in the future
Not something to take lightly

Trust and transparency and Cochrane
Transparency at the heart of EBM
Primary function to conduct high quality systematic reviews..
Hill S, Kaufman J, Dilkes H 2011

Threats: Conflict of Interest
What is it? Circumstances that create a risk that
professional judgments or actions regarding a primary interest will be unduly influenced by a secondary interest (Bero, L)
A risk—not necessarily the existence of biased judgment or action
![Page 7: TRUST AND TRANSPARENCY Dr David Tovey FRCGP Editor in Chief, The Cochrane Library](https://reader035.vdocuments.site/reader035/viewer/2022062620/551b17bf5503465e7d8b639f/html5/thumbnails/7.jpg)
Does it matter?
“Even the most enthusiastic Manchester United fan wouldn’t think it right for Sir Alex Ferguson to referee the match” (Godlee, F)
![Page 8: TRUST AND TRANSPARENCY Dr David Tovey FRCGP Editor in Chief, The Cochrane Library](https://reader035.vdocuments.site/reader035/viewer/2022062620/551b17bf5503465e7d8b639f/html5/thumbnails/8.jpg)
Cochrane Collaboration COI policy
“Sponsorship of a Cochrane review by any commercial source or sources is prohibited.”
All review authors complete COI form pre-publication
Allows: Financial ties of authors (disclose) Industry employees as authors (minority of authors
within team)

Conflicts of interest
Physician rewards programmes “Hospitality” and CME Enrolment into research Sponsorship of clinical trials Participation in conduct and reporting of
research Involvement in evidence synthesis and
guidelines programmes

Conflict of interest in research "There is a serious problem of trust and
trustworthiness in at least some industry-sponsored research. It is unjustly exploitative of human subjects to allow them to imagine that they are contributing to the advance of science if in fact the design of the study has been manipulated specifically to obtain data that the company will use to it's marketing advantage rather than answer any scientific question of real interest or importance."Howard Brody

Financial ties of guideline committee members
Cross-sectional survey of 192 authors of 44 guidelines endorsed by NA and European societies (52% response)
59% had financial relationships with companies whose drugs were considered in the guideline (almost all pre-dating)
95% not declared in published CPG Choudhry et al, JAMA 2002

There is a real dilemma though..... “The only person who doesn’t have a
vested interest in a subject is somebody who knows nothing about it” (Richard Smith ex Editor BMJ)

Results:•102 trials, 3736 outcomes•50% efficacy and 65% harms outcomes / trial incompletely reported•Statistically significant outcomes more likely to be correctly reported than non significant outcomes

laundering operations for the pharmaceutical industry”

Trust and transparency in research
“in the publication of research results, the investigators are obliged to ensure the accuracy of the results. Negative as well as positive results should be published or otherwise made publicly available..”
Idanpaan-Heikkila J E, Fluss S

What can be done?
Cochrane statement: “All randomised clinical trials to be registered
at their inception, before recruitment of the first participant
All data from all randomised clinical trials and the corresponding trial protocols to become publicly available free of charge and in easily accessible electronic formats
Need to hold and make available core data indefinitely

What can be done?
Continued: Governments to consider punitive
measures for non-compliance Governments to consider introducing
legislation requiring data from all trials to be made public within 12 months from the end of the randomised phase of the trial
Recognition that ownership of trial data should be shared between sponsors, investigators and trial participants”

What about guidelines?
![Page 37: TRUST AND TRANSPARENCY Dr David Tovey FRCGP Editor in Chief, The Cochrane Library](https://reader035.vdocuments.site/reader035/viewer/2022062620/551b17bf5503465e7d8b639f/html5/thumbnails/37.jpg)
Guidelines: the way forward
WHO and IOM setting high standards Disclosure necessary but not sufficient Importance of transparency: guidelines
agency and panel members Role of chair-person Exclusion (partial or complete) of conflicted
members Broad view of COI
