Objective:To explore the countermeasures to strengthen hospital scientific research management and prevent research misconduct by studying the characteristics of research misconduct cases investigated by the NSFC in recent three years.Methods:Information of a total number of 67 research misconduct cases in 6 batches that publicly reported by the NSFC from 2019 to 2021 were collected, classified statistics were conducted on the situation of the supporting units involved, the specific issues of Misconduct and the disciplinary measures of the NSFC. According to the frequency proportion of misconduct problems, the tendency characteristics and reasons were analyzed and summarized, countermeasures and suggestions were put forward.Results:96.36% of the main responsibility entity of research misconduct was individuals, and 3.63% of the main responsibility of relying institution. There were 62 cases of research misconduct due to scientific papers and applications, accounted for 92.50%. Among the problematic papers involved, data fraud accounted for 48.20%, false signature or unauthorized signature accounted for 35.97%, plagiarism accounted for 32.37%, and unauthorized marking of other people′s fund number accounted for 27.33%. The NSFC revoked 55 fund projects involved and recovered funds, 67 people were disqualified from applying for projects with a maximum of 7 years and a minimum of 2 years, and 2 peer-review experts were punished.Conclusion:Hospital scientific research management should draw lessons from others, and put forward specific countermeasures from the aspects of strengthening scientific research integrity education, improving the construction of supervision mechanism, strictly implementing process management and perfecting scientific research credit evaluation system, in order to provide possible reference for preventing misconduct in hospital scientific research management practice.
