Dr Owen Smith said yesterday that he had been "upset" by allegations of insensitivity which were made against him at the tribunal last year by the father of a haemophiliac who died of liver failure in 1996.
The witness, who was identified by the pseudonym Peter, had criticised the manner in which his son, Dermot, had been informed that he was terminally ill.
Peter said he believed it was cruel and insensitive for Dr Smith to have broken the news to Dermot when there were no family members present.
But Dr Smith said he thought there was "nothing I would change now in relation to the last days of Dermot's life".
He said he had had a "very good relationship" with the patient, who was aged 39, and whom he had known for some time.
Dr Smith said that Dermot had asked him whether he was going to die and "asked me to be frank".
He said that once he informed Dermot of the most likely outcome of his illness he arranged for his parents and sister to come to the hospital.
Dr Smith said that "everybody pulled out the stops" for Dermot, including nurses and junior doctors.
"Also, I devoted a lot of time . . . so at the end of Peter's statement I was somewhat upset", he added.
