Study Finds Nearly 2 Years Between Completion, Publication of Clinical Trials

 

In a research letter, Joseph S. Ross, M.D., M.H.S., of the Yale University School of Medicine, New Haven, Conn., and colleagues report that, on average, nearly two years passed between completion and publication of clinical trials, across all funders, in 2009. (Online First)

 

There were 1,336 clinical trials published during the calendar year and the median time to publication was 21 months, according to the study results. There also were only modest differences across the types of trials. For example, median (midpoint) time to publication was longer among trials funded by industry compared with trials funded by government and nonprofit organizations (24 vs. 20 months), according to the study results.

 

“Given the time required to publish results from these clinical trials, our findings support current federal initiatives requiring results reporting of clinical studies within 12 months of trial completion to ensure the timely dissemination of clinical science,” the study concludes.
