A service of the U.S. National Institutes of Health Module 3: The Librarian’s Role in Advocating to Clinical Researchers
Increased Requirements for Registration and Results Reporting • Selective publication makes it difficult to determine the true value of a treatment • Comparisons of published drug trials with unpublished trials or other available data have shown that the benefits of a number of drugs have been much overrated and the harms much underrated • As a result, FDAAA law and ICMJE policy require clinical trial registration and results reporting to increase access to clinical trial data
Results Posting • Rate of studies with results posted has significantly increased since the launch of the ClinicalTrials.gov results database in September 2008
“No Study Results Posted” • Not subject to FDAAA requirements to submit results • Still ongoing • Completed, but still prior to deadline for results submission • Results have been submitted, but not yet posted • Delayed due to certification or request to extend the results submission deadline
Challenges in Submitting Results • Lack of awareness of results submission requirements • Results submission must be completed by someone familiar with the study and data and experienced with ClinicalTrials.gov tabular format
Advocating to Others • Patients can use ClinicalTrials.gov find clinical trials and make informed decisions with their health care provider about whether to participate • Health professionals and researchers can use the ClinicalTrials.gov results database and links to PubMed citations to find results information
Summary • Outcome reporting and publication biases prompted laws and policies requiring clinical trial registration and results reporting • ClinicalTrials.gov Results Database has increased every year since inception, but needs assistance from librarians to increase access to all clinical trial data • Librarians play an important role in advocating, educating, and assisting clinical researchers with registration and results reporting requirements
