Health care is full of hard decisions.
Those decisions are often made harder by the glare of media attention, and an inadequate assessment of risk by patients and doctors. An example might be the patient who is awaiting an operation and has been concerned by the risk of blood-borne infection of hepatitis or HIV from blood transfusions. The obvious answer is for the patient to donate his or her own blood before the operation, to be used during the operation - autologous blood transfusion. That would avoid the danger of infection, and nothing could be simpler. The methods they used were essentially simple.
