Disciplinary Decision concerning Dr. Yoshitaka Fujii

Dr. Yoshitaka Fujii was an associate professor of Anesthesiology, Toho University Faculty of Medicine. The credibility of Dr. Fujii's 9 publications (see list below), which were published in foreign journals under the name of Toho University, was put in doubt in August, 2011. Toho University, therefore, organized an investigation committee in September, 2011, and made a searching inquiry into their credibility. The committee reached the following decision:

Since all of Dr Fujii’s clinical studies that appeared in these 9 publications were conducted at Ushiku Aiwa General Hospital, which has no relation to his research activity in Toho University, the investigation committee contacted the head of the hospital. As far as the head of the hospital knows, there was only one clinical study listed by Dr. Fujii as having been conducted at the hospital. The other eight clinical studies were conducted without any ethics committee’s approval, and this was judged sufficient to decide that 8 of his publications (No. 2 to 9) should be retracted since they did not conform to the global standard of ethics for clinical studies. After the investigation, the committee asked Dr. Yoshitaka Fujii and his co-author, Dr. Michiyo Itakura, to explain the whole circumstances. Dr. Fujii admitted that the clinical studies were done without any ethics committee’s approval. Dr. Itakura, however, was not involved in this misconduct. Dr. Yoshitaka Fujii sent letters of retraction to the affected journals. We organized a disciplinary committee and decided that a disciplinary dismissal was appropriate for Dr. Fujii, effective from February 29, 2012. Dr. Fujii has already been dismissed from Toho University.
