Cochrane Collaboration Urges Free Access to All Data From All Clinical Trials: End to Selective Reporting Can Reduce the Risk of Harm to Patients

From the Cochrane Collaboration:

An international non-profit organisation committed to providing the most reliable evidence of the benefits and harms of healthcare interventions has released a statement calling for free access to all data from all clinical trials in order to provide the best care for patients globally.

In its statement, The Cochrane Collaboration argues that selective reporting of trial results occurs frequently, leading to exaggerated findings of the beneficial effects of healthcare interventions and to underestimates of their harms. As a consequence, many patients are unknowingly treated with interventions that have little or no effect and may be harmed unnecessarily.

Jeremy Grimshaw and Jonathan Craig are the Co-Chairs of The Cochrane Collaboration’s Steering Group. Craig says, “The Cochrane Collaboration strives to provide the best health evidence so patients can receive the best treatment. This evidence includes access to all clinical trial data and it should be mandatory that this information is freely available.”

The statement produced by the Collaboration calls for the following:

  • all randomised clinical trials to be registered at their inception, before recruitment of the first participant;
  • all data from all randomised clinical trials, including raw anonymised individual participant data that do not allow identification of individual participants, and the corresponding trial protocols to become publicly available free of charge and in easily accessible electronic formats;
  • 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, in accordance with most international calls for data sharing; and
  • governments to also consider the following measures: punitive measures for non-compliance; a requirement to continue to hold and make available core data indefinitely, or to pass such data to a central and accessible repository; and recognition that ownership of trial data should be shared among sponsors, investigators and trial participants.
