Now Published: CONSORT 2010 Statement

New guidance to improve the reporting of trial findings is published simultaneously today (24 March 2010) by nine leading journals around the world "“ BMJ, Annals of Internal Medicine, BMC Medicine, Journal of Clinical Epidemiology, Lancet, Obstetrics and Gynecology, Open Medicine, PLoS Medicine, and Trials.

Full and transparent reporting of trials is crucial to ensure that decisions about health care are based on the best available evidence. 

The guidance, known as the Consolidated Standards of Reporting Trials (CONSORT) statement, was first published in 1996 and revised in 2001. It includes a checklist to help authors write reports of randomized controlled trials so that others can judge the reliability and validity of the results. 

More than 400 journals and three leading editorial groups across the world have now given their official support to CONSORT. 

The latest version, CONSORT 2010, improves the specificity and clarity of the previous checklist. Several new items will also make it easier for decision makers to judge the soundness of trial results. A separate explanatory paper, also published today in the BMJ and the Journal of Clinical Epidemiology provides published examples of transparent reporting and elaborates on the empirical evidence that forms the basis for the guidance.

Speaking on behalf of coauthors, Douglas Altman and David Moher, and for the CONSORT Group, Kenneth Schulz, Distinguished Scientist and Vice President of Family Health International in the US emphasizes that CONSORT 2010 represents an evolving guideline. He says: "In the future we will further revise the CONSORT material considering comments, criticisms, experiences, and accumulating new evidence. We invite readers to submit recommendations via the CONSORT website."

As with the previous revision between 1996 and 2001, the publication of CONSORT 2010 now makes the previous version, CONSORT 2001 Statement, out-dated. Authors, editors, reviewers and readers are recommended to refer to this most up-to-date version while writing or interpreting reports of clinical trials.

A study by Sally Hopewell et al(1) also published by the BMJ today to accompany the guidance shows that, although the quality of trial reporting has improved since publication of the CONSORT statement in 2001, it remains well below an acceptable level. The researchers conclude that more journals should endorse CONSORT and, most importantly, they should do more to ensure adherence. 

This view is supported in an editorial(2) which says that the guidance is clear, but awareness and endorsement are lagging behind. Author Gerd Antes, Director of the German Cochrane Centre, believes that journal editors should do more to incorporate the CONSORT checklist into the peer review process. He also warns that, although CONSORT has been translated into 10 other languages, not much is known about endorsement and adherence in those areas.
