The study looked at the publication record of academically led clinical trials in the USA. It was led by Yale University. More than 5000 trials were identified as starting between October 2007 and September 2010. A number of these were excluded, leaving 4347 across 51 academic institutions to be analysed. Overall 2892 (66.5%) had been published by July 2014. The study has a comprehensive analysis by type of trial and intervention, institution etc and certainly satisfied me it had considered all the issues. It came to the sad conclusion that publication rates are very variable and there is “poor performance across leading academic medical centers in the dissemination of clinical trial results.”
The focus for All Trials has been on industry studies and great steps have been achieved. However this BMJ study shows that the academic world needs closer examination and needs to be provoked into action too. In Europe it may be less of a problem but we don’t know, we certainly cannot be sure. We have clear commitments about publishing from the European Organisation for Research and Trials on Cancer (EORTC) and from many leading academic collaborative groups, national and multi-national. Individual institutions have made commitments too but what is the real story? We don’t know. Is the positive action from the prominent few allowing others to hide away, ignoring the issue in the hope it will go away?
We don’t actually need a study like the one from the USA. We could just start to take action.
The best way of finding out would be through the registration authorities. Each sponsor should provide a simple table of studies sponsored, completion information and planned publication dates, regularly updated and made publicly available. This table could be entitled The Patient Covenant. Any sponsor (quite often these are academic bodies) which has outstanding trial publications should be unable to register any new trial until their obligations are met.
In addition any principal investigator taking a study to ethics for approval should have his study placed on hold if trial publications are outstanding. This would give a two-tier coverage and will stop institutions breaching their covenant with patients.
“As patients we should be quite uncompromising about trial publication”
As patients we should be quite uncompromising about trial publication. There are no excuses for not publishing. Failure to do so violates the explicit promise made to patients entering the trial that it aims to provide clinical evidence, even failure to achieve a trial objective can still provide evidence. Not publishing impairs understanding and threatens the integrity of clinical evidence, squandering resources in doing so.
I was very taken by four verbs used in the conclusion of the study published by BMJ. Think about them. I use them above and I list them out of context below because I think it adds to their impact:
If you are reading this you know the context; avoid these blistering criticisms.
