The demand for blood in England and Wales and the United States

This chapter examines the demand for blood in England and Wales and the United States. Between 1948 and 1967, the annual number of donations of blood in England and Wales rose by 269 per cent. Some part of this increase in supply has met the increase in the amount of blood actually demanded and used per 100 patients treated in hospitals. Meanwhile, estimates have been made that 5,100,000 pints of blood were collected in the United States in 1956 and around 6,000,000 pints in 1966-7. Some of the factors responsible for this world trend relate to the major life-saving role of blood. Others are adding yearly to the relatively new role for human blood of acting as a vital preventive and therapeutic agent. Surgery in its many branches has, for example, been given a new lease of life by increases in the volume of blood available and the advent of effective blood transfusion services.
