A leading doctor treating haemophiliacs has admitted that he did not speak to the Department of Health before telling the blood bank that hospitals could not afford a safer, but more expensive, product. The Lindsay Tribunal heard that Professor Ian Temperley wrote to the Board of the Blood Transfusion Service in 1988 giving his advice on what clotting agents should be bought. He said that in a period of financial stringency, the hospitals could not be expected to meet a doubling of the cost of blood concentrates in 1989.
