The Leiden University Medical Center (LUMC) has asked an international scientific journal to withdraw two publications by a former employee. The scientist manipulated data sets in these two publications, thereby creating false results. The scientist left the LUMC some time ago, but currently works at a foreign university. The LUMC has informed this university. 

The manipulation came to light after a PhD student reported the matter. The publications related to very specific molecular research and were not patient-related. This means that patient safety was never compromised.

Investigation 

Prof. Pancras Hogendoorn, member of the Board of Directors and dean of the LUMC says: “This is a deeply regrettable incident. Following a report from a PhD student, the LUMC performed an internal investigation. Initially no conclusive evidence was found. However, new facts about the cases were uncovered during an investigation by the Netherlands Board on Research Integrity (LOWI). The LUMC subsequently started a new investigation. This investigation resulted in a different conclusion. The result of the investigation now clearly revealed that data sets were deliberately manipulated by one employee.”

“We are grateful to the PhD student who revealed the manipulation”, says Hogendoorn. “We place great importance on scientific integrity. I think that it is of vital importance to gain and preserve the trust of patients, scientists and society.”

Integrity codes

The LUMC works according to integrity codes based on the national codes of conduct. The Confidential Advisor can answer questions about integrity. There is also a Complaints Committee that investigates complaints about possible violations of scientific integrity. Of course, good employment practice is also important: a person is innocent until proven guilty.
