Informatics Research Seminar: The Effectiveness of Correction as Quality Control in Biomedical Literature- Does Correction Reduce Patient Risk?

March 27, 2019 @ 4:00 pm - 5:00 pm EDT

Speaker: Gabriel Peterson, PhD

Presented from NCCU

Broadcast Link: Seminar


Correction and republication provide a mechanism for identifying and updating non-maleficent but message distorting errors in biomedical literature. Inappropriate use of anomalous literature is spread by the citation of invalidated scholarly works. It is known that republished versions are cited more often than corrected versions of articles. The strength of invalidation correction and republication can be quantified. This presentation summarizes an analysis of 15,000+ citations to 548 articles indexed in PubMed. The bibliometric analysis described shows that corrected articles are cited about 51% less than controls. Thus, the practice of correction and republication leads to a reduction in the citation of flawed works that is fast-acting and long-lasting.  Though it is not possible to quantify patient risk, the corrective effect is also visible when human subjects involved in secondary research are considered.  Not only does correction reduce inappropriate citation, it also leads to reduced patient risk in later research.


Dr. Gabriel Peterson, PhD, is an Associate Professor at the School of Library and Information Sciences at North Carolina Central University in Durham, NC. He holds bachelor’s degrees in Biochemistry (BS), Chemistry (BA), and Spanish (BA) from New Mexico State University, and an MS in Biotechnology from the University of Texas at San Antonio. He earned his Doctorate in Information Science from the University of Missouri in 2006.  He joined North Carolina Central University School of Library and Information Sciences in 2007.

Dr. Peterson’s research interests pertain to the intersection of health sciences and biomedical literature and the Information Society. Health literacy and access to scientific and health information can improve lives by reducing health information disparities so it is important to understand how to make high-quality information accessible to those who can benefit most from it. One aspect of his research focuses on scholarly communication and the use of health information: He studies the self-correcting attributes of science.  He is the author of the 2013 article, “Characteristics of retracted open access biomedical literature: a bibliographic analysis” and the 2019 brief communication, “The effectiveness of correction and republication as quality control in scholarly communications – a bibliometric analysis” in the Journal of the American Society of Information Science and Technology.  His current research examines the impact of anomalous literature on human subjects and healthcare searching/seeking behaviors.
