The General Medical Council (GMC) is to hear the case of a foreign locum doctor who injected a patient with 10 times the recommended daily dosage of a pain relief drug.
David Gray, 70, died at his home in Manea, Cambridge, a few hours after being treated by German Dr Daniel Ubani in February 2008. He was given a fatal overdose of 100mg of diamorphine while Dr Ubani was working in the country for the first time, for SuffDoc, which is part of the out-of-hours GP service provider Take Care Now.
Dr Ubani has been invited to attend the Fitness to Practise hearing at the GMC in Manchester but is not expected to be present. He continues to work as a doctor in Witten, Germany, but is currently suspended from the UK medical register.
Mr Gray's sons, Stuart and Rory, are both planning to attend Wednesday's hearing, which will also look into the care given to two other patients treated by Dr Ubani during the same shift.
The hearing will investigate allegations that Dr Ubani's conduct was "not at a standard to be expected of a reasonably competent GP".
As a result of the hearing, he could be struck off the medical register so he can no longer practise in the UK.
