Summary of professional career
Fujii graduated from
In February 2012, after initial investigations into allegations of scientific misconduct, he was dismissed from his position as associate professor of anesthesiology in the Toho University Faculty of Medicine.[6]
Research misconduct
Fujii apparently began publishing falsified data in 1993.
Two analyses of some of Fujii's publications were released in March 2012. On 7 March, Toho University reported finding that although nine of Fujii's publications were about clinical studies described as having been conducted at
In April, the editors of 23 scientific journals made a public request for an investigation of Fujii's research by the seven Japanese institutions named as affiliations in his published papers.
The investigators observed that Fujii seemed to have been deliberately ambiguous about details such as the dates of the studies and the names of the institutions where they were conducted, apparently to reduce the possibility that his fraud would be detected. Also, by listing co-authors from institutions other than his current employer, he conveyed the impression that the papers described studies done at multiple hospitals.[12] Several scientists listed as co-authors were not aware that Fujii had included their names on his papers; two named co-authors said that their signatures had been forged on a cover letter submitting the paper to the journal.[2][12] Retraction Watch suggested that the supposed co-authors might not have been aware that their names had been misused because the papers had received few citations.[2][13] Investigators found that one of Fujii's co-authors, Hidenori Toyooka, who collaborated with Fujii on "dozens" of papers, may have been aware of the deception.[12]
As of 2023, 183 of Fujii's research publications have been retracted, and 47 other papers have received an expression of concern.[1] According to Retraction Watch, Fujii has the second most retractions of scientific papers by a single author as of September 2023[update].[14] He was at the top of Retraction Watch's leaderboard until July 2023, when he was surpassed by German anesthesiologist Joachim Boldt.[15]
