Journals retract doctor’s drug claims

Have your say

The editors of 16 medical journals have retracted “unethical” research carried out by a German doctor on drugs used in the UK.

Anaesthetist Dr Joachim Boldt is at the centre of an investigation in to more than 100 studies, including those on medicines known as colloids, which boost blood volume in surgical patients.

The doctor worked at the Klinikum Ludwigshafen hospital in the city of Ludwigshafen.

In an open letter on Wednesday, the editors of international journals, including Anaesthesia and the British Journal of Anaesthesia, said 89 of 102 studies published by Dr Boldt were found not to have approval from an institutional review board (IRB) in Germany.

Dr Rupert Pearse, a consultant at Barts in London said: “There are no immediate safety concerns for patients.”
