Two days before the end of 2021, administrators at Jining First People’s Hospital in Shandong, China, issued a highly unusual report. The hospital announced that it had disciplined 35 researchers who had been linked to fraud in publications, such as fabricating data. These sanctions were part of a countrywide crackdown motivated by concerns about a flood of sham medical papers emanating from hospitals.
The problem was that some young physicians at hospitals had purchased fake manuscripts from paper mills: companies that churn out fraudulent scientific reports to order. These doctors were under pressure because they were required to publish papers to get jobs or earn promotions, says integrity sleuth Elisabeth Bik in California. Sleuths such as Bik soon began spotting signs of this problem, identifying duplicated images in large numbers of papers. They publicized the issue and a wave of retractions followed.
This surge can now be seen in a first-of-its-kind analysis of institutional retraction rates around the globe over the past decade, for which Nature’s news team used figures supplied by three private research-integrity and analytics firms. Jining First People’s Hospital tops the charts, with more than 5% of its total output from 2014 to 2024 retracted — more than 100 papers (see ‘Highest retraction rates’). That proportion is an order of magnitude higher than China’s retraction rate, and 50 times the global average. Depending on how one counts, the hospital could be the institution with the world’s highest retraction rate.
