Collection and transfusion of blood and blood components in the United States, 1994

Abstract

The US blood collection rate in 1994 was 74.6 units per 1000 population of donor age, the lowest recorded level since 1971. The US RBC transfusion rate in 1994 was 42.8 units per 1000 population, about the same as 1979. Transfusions of single-donor platelets, 16.5 units per 1000 population, exceeded transfusions of platelet concentrate (13.8/1000) for the first time. Plasma transfusions were 10.1 units per 1000 population. The US blood supply in 1994 was adequate to meet patient demands.
