Poldermans misconduct report finds lack of patient consent, sloppy data collection and data fabrication

November 21, 2011

Over the weekend Erasmus University published their executive summary (in Dutch) of the investigation which resulted in the dismissal of Professor Don Poldermans. The investigation commission included members from Erasmus, Leiden and Amsterdam Medical Centres.

Prof. Dr. P.J. van der Maas, former dean of Erasmus MC (Chair)
Prof. Dr. B. Löwenberg, Emeritus Professor of Hematology, Erasmus MC
Prof. Dr. R.J.G. Peters, Professor of Cardiology, Amsterdam MC
Prof. Dr. A.J. Rabelink, Professor of Internal Medicine, Leiden UMC
Mr. J.M. Oosting, head of Legal Affairs, Erasmus MC
Administrative support is provided by Dr. RE Juttmann and Dr. R.M. Struhkamp.
Poldermans was the leader of the Dutch Echocardiographic Cardiac Risk Evaluation Applying Stress Echocardiography (DECREASE) studies:

DECREASE I: In high-risk patients undergoing non-cardiac surgery, perioperative beta-blockade with bisoprolol significantly reduces cardiac death and MI in the short- and long-term

DECREASE II: Patients identified as intermediate risk on the basis of a simple clinical assessment do not need pre-operative echocardiographic cardiac stress testing, provided that they receive bisoprolol to maintain resting heart rate at 60–65 b.p.m.

DECREASE III: In high-risk patients undergoing major vascular surgery, fluvastatin XL significantly reduces myocardial ischaemia and the combined endpoint of cardiovascular death and MI

DECREASE IV: In intermediate-risk patients, bisoprolol significantly reduces cardiac death and MI, with a non-significant trend towards a beneficial effect of fluvastatin XL

DECREASE V: In high-risk patients with extensive stress-induced ischaemia, coronary revascularization (added to tight heart rate control with bisoprolol) does not produce any additional reduction in death and MI and delays surgery.

 DECREASE VI: is a trial for testing NT-proBNP for the evaluation of cardiac risk in patients undergoing vascular surgery.

The investigation concluded that there were serious deficiencies in getting patients’ consent for inclusion in the studies, that data collection was sloppy and that data was fabricated. However no patients were harmed. Data manipulation was not found. The responsibility for the misconduct was that of the Professor Poldermans and not of any of the other researchers. The Commission found several serious errors and protocol violations in the D2 and D6 studies and possibly in D4. Evidence of data fabrication was found in submitted abstracts for the D6 study (not published).

The D6 study sponsored by Roche Diagnostics is to be discontinued.

The Commission believes that the Journal which published the D2 study should be informed (The Journal of the American College of Cardiology) but that retraction of the publications was not needed.

Erasmus University, Rotterdam sacks Professor of cardio-vascular medicine for scientific misconduct

Universities in Holland are having a torrid time with another dismissal for scientific misconduct, this time at Erasmus University in Rotterdam. But the seriousness with which investigations are carried out and the speed and decisiveness with which Dutch Universities act is quite impressive.

Professor Don Poldermans, MD, PhD, is was  Professor of Medicine and head of the section perioperative cardiac care of the Erasmus Medical Centre, Rotterdam, the Netherlands. Dr Poldermans received his medical degree at the Erasmus Medical Centre in 1981. He is a fellow of the European Society of Cardiology and an honorary member of the Dutch Society of Anesthesiology. He is active within the Departments of Anesthesiology, Internal Medicine, and Surgery of the Erasmus Medical Centre, Rotterdam, the Netherlands.

Dr Poldermans is actively involved in patient care, education, research, and administration. He supervised 26 PhD students, all working on cardiovascular research. He has published more than 600 manuscripts in several peer-reviewed Journals, including the New England Journal of Medicine, Lancet, JAMA, Circulation, and the Journal of the American College of Cardiology.

Dutch News:

Erasmus University in Rotterdam has sacked a professor in cardio-vascular medicine for damaging the institution’s academic integrity and for ‘scientific misconduct’, the NRC  reports on Thursday.

The professor is accused of faking academic data and compromising patient trust, the paper says. In particular, he failed to obtain patient consent for carrying out research and recorded results ‘which cannot be resolved to patient information,’ the university said.

Don Poldermans has spent years researching the risk of complications during cardio-vascular surgery and has some 500 publications to his name.

A spokesman for Poldermans told the paper he admitted not keeping to research protocols but denied faking data.

Last month, Tilburg and Groningen universities said they planned to take legal action against behavioural science professor Diederik Stapel after an investigation showed he had faked research data in at least 30 scientific papers.

According to Elsevier, an investigation committee brought the fraud to light. It found that Poldermans had taken blood samples and heart echoes from patients without their permisssion and has reported results which cannot be traced to any patient.
“Patients were not physically harmed,” emphasizes Dean and Director Huib Pols. He said he was deeply shocked by the case. Patients who participated in the latest survey receive a letter of apology from the hospital.
