背景 (1)研究西班牙地区间、单一地区(安达卢西亚)、医院间的红细胞、血小板、血浆输血的变化;(2)确定这些地区输血和献血率间的关系。材料和方法 从17个地区的管理部门8个安达卢西亚省、安达卢西亚的30家医院获得数据。研究用数据包括献血率、每千名居民中每种成分的输血率、每千个住院日的输血率。结果 在所有地区中,最大变化是血小板输血[变异系数(VC)=54.8％],红细胞输血次之(VC=21.2％),献血率与红细胞、血小板输血密切相关,与输血浆无关。在安达卢西亚省,最大变化是血小板输血(VC=61.3％,红细胞输血次之(VC
Background (1) To study the changes in blood transfusions between red blood cells, platelets, and plasma in inter-regional, single-regional (Andalusia), hospitals, and between hospitals; and (2) to determine the relationship between transfusion and blood donation rates in these regions. Materials and Methods Data were obtained from 30 hospitals in eight administrative departments of Andalusia and Andalusia in 17 districts. Research data includes blood donation rates, blood transfusion rates for each component per 1,000 residents, and blood transfusion rates per 1,000 hospital days. Results In all regions, the greatest change was platelet transfusion (Variability Coefficient (VC) = 54.8%), red blood cell transfusion was second (VC = 21.2%), and blood donation rate was closely related to red blood cell and platelet transfusion, and was not related to plasma transfusion. In Andalusia, the greatest change was platelet transfusion (VC = 61.3%, followed by red blood cell transfusions (VC)
