Joachim Boldt published 90+ anesthesia papers on patients he never treated

Joachim Boldt, a German anesthesiologist at Klinikum Ludwigshafen, published over 90 research papers between 1999 and 2010, primarily on the use of hydroxyethyl starch (HES) solutions in surgery. His papers were widely cited and influenced clinical practice across Europe.

In 2010, an investigation revealed that Boldt had not obtained ethics committee approval for most of his studies, and that many of the patients described in his papers had never existed. The data were fabricated. Over 90 of his papers were retracted — one of the largest mass retractions in medical history.

The case was particularly damaging because Boldt's research had promoted the use of HES solutions, which were later found to cause kidney damage and increase mortality. Hospitals that had adopted HES protocols based on Boldt's work had to revise their practices. The case illustrated how fabricated research can directly harm patients when it influences clinical practice, and how the peer review system can fail to detect fabrication when the data appear plausible.
