Joachim Boldt

As of 2017, 96 papers have been retracted. In October 2018 a review highlighted additional retractions - the oldest paper retracted was from 1986, demonstrating persistent fraud for the entire career of Boldt. Statistical analyses demonstrate that still many most likely fraudulent papers from Boldt are out there and editors should take action. In December 2019 three more of his clinical trials have been retracted, so he is now scoring 100, the second highest number of retractions according to the leaderboard of Retraction Watch. http://retractionwatch.com/category/joachim-boldt-retractions/

On February 20, 2013, JAMA published a metaanalysis on HES in critically ill patients (Zachyranski R et al.) Boldt had 7 studies from the 1990s that had not yet been retracted. Including them, there was no increase in mortality, but excluding them, there was a significant increase in mortality. Only the Boldt studies showed an improvement with HES; all other studies showed no benefit but significant risks. It is believed that his fraudulent studies put critically ill patients at risk and caused harm.

In August 2012, the hospital released the results of the investigation: while no patients were harmed, "in a large number of the studies investigated, the conduct of research failed to meet required standards. False data were published in at least 10 of the 91 articles examined, including, for instance, data on patient numbers/ study groups as well as data on the timing of measurements".

In February 2011, Boldt was stripped of his title of professor at the University of Giessen for failing to teach, and the university is investigating possible charges of scientific misconduct. His case was described at the time as "possibly the biggest medical research scandal since Andrew Wakefield was struck off in 2010 for falsely claiming to have proved a link between the MMR vaccine and autism".

On November 10, 2010, Boldt was suspended from Klinikum Ludwigshafen, a hospital in Germany, for a scientific publication in Anesthesia & Analgesia with insufficient background research. His field of research and the publications were related to hydroxyethyl starch (HES). Some 90 studies he published are currently being reviewed by medical authorities.

Joachim Boldt (born September 29, 1954) is a German anesthesiologist who was previously considered a leading researcher of medicinal colloids. He was an advocate for the use of collodial hydroxyethyl starch to boost blood pressure during surgery. He has been stripped of his professorship and is under criminal investigation for possible forgery of up to 90 research studies.
