Context Analysis of Continued Citation of Retracted Manuscripts Published in Anesthesiology Journals.

Abstract

The continued citation of retracted publications from the medical literature is a well-known and persistent problem. We describe the contexts of ongoing citations to manuscripts that have been retracted from a selection of anesthesiology journals. We also examine how bibliographic databases and publisher websites document the retracted status of these manuscripts. The authors performed an analysis of retracted publications from anesthesiology journals using the Retraction Watch database. We then examined how the retraction information was displayed on bibliographic databases, search engines, and publisher websites. The primary outcome was the context of continued citation after retraction of flawed publications within the specialty of anesthesiology. Secondary outcomes included comparison of the documentation, bibliographic databases, search engines, and publisher websites used in identifying the retracted status of these publications and provision of access to the respective retraction notices. A total of 245 original publications were retracted over a 28-year period from 9 anesthesiology journals. PubMed, compared to the other databases and search engines, was the most consistent (98.8%) in documenting the retracted status of the publications examined, as well as providing a direct link to the retraction notice. From the 211 publications retracted before January 2020, there were 1307 postretraction citations accessed from Scopus. The median number of postretraction citations was 3.5 (range, 0-88, with at least 1 citation in 164 publications) in Scopus. Of the postretraction citations, 80% affirmed the validity of the retracted publications, while only 5.2% of citations acknowledged the retraction or misconduct. In 10.2% of the citations from original research studies, retracted manuscripts appeared to influence the decision to pursue or the methods used in subsequent original research studies. The frequency of citation of the 15 most cited retracted publications declined in a similar pattern during the 10 years after retraction. Citation of manuscripts retracted from anesthesiology journals remains a common occurrence. Technological innovations and application of standards for handling retracted publications, as suggested by coalitions of researchers across the spectrum of scientific investigation, may serve to reduce the persistence of this error.
