目的通过对河北省血液中心近年来固定献血人群及采血量变化进行分析,探讨固定献血者比例概念的应用效果和实际意义,为发展固定献血者队伍,提高采血效能提供参考。方法对2012-2016年河北省血液中心固定献血者人数、献血人次和献血量进行公式定义并提取数据,与对应年份献血总人数、总人次和总血量做比例测算,将有关数据做统计学分析,P<0.05为有统计学差异。结果近年来,河北省血液中心采血量逐年增长,固定献血者人数比例、人次比例和血量比例均呈上升趋势,但增幅各不相同,与总量增幅呈负相关性。结论单纯以固定献血者人数比例为指标不能准确评价血液有效采集能力,以固定献血者献血量比例作为考量献血者保留效果和当地血液满足程度,具有一定的指导意义。
Objective To analyze the effect of blood donation and fixed blood donation in Hebei Blood Center in recent years and to explore the application effect and practical significance of the concept of proportion of fixed blood donors so as to provide reference for the development of fixed blood donors and blood collection efficiency. Methods The number of blood donors, blood donors and blood donations in blood center of Hebei province during the period of 2012-2016 were defined and extracted according to the formula, and the total number of blood donations and total blood volume were calculated according to the corresponding years, and the data were statistically analyzed Analysis, P <0.05 for statistical differences. Results In recent years, the amount of blood collected from blood centers in Hebei Province increased year by year. The number of fixed blood donors, the proportion of persons and the proportion of blood showed an upward trend. However, the increases were not the same and negatively correlated with the increase of total amount. Conclusion The proportion of fixed blood donors alone can not accurately evaluate the blood collection ability. Taking the proportion of donated blood of fixed blood donors as a reference to consider the retention effect of blood donors and local blood satisfaction, it is of guiding significance.
