背景：早期对输血流行病学特征的调查并非基于社区总人口。为了计算一般人群以及特定年龄和性别群体中输血和血液成分的发生率，对 1989 年至 1992 年期间接受过输血的美国一个县的所有居民进行了研究。 研究设计和方法：该研究是在特定时间对明确人群进行的流行率调查（横断面研究）。结果：从 1989 年初到 1992 年，血液和血液成分的利用没有显着变化。男性和女性的红细胞输血发生率均为每年每 1000 人 42.88 单位，从 41 岁以下人群每年每 1000 人 12.08 单位到 65 岁以上人群每年每 1000 人 245.24 单位不等。随机居民在任何年份接受输血的概率为 0.89%（男性和女性为 0.83%）。女性为 0.94%），三个年龄组的比例从 0.26% 到 5.17% 不等。血小板和新鲜冰冻血浆输注的发生率分别为每年每 1000 人 21.24 单位和每年每 1000 人 8.64 单位。结论：此处首次提出了“因果”采血计划的输血发生率。任何一年接受红细胞输注的概率从40岁以下的人群到65岁以上的人群增加了20倍，65岁以上的人群接受了53.3%的红细胞单位输血。
Background: Earlier investigations of the epidemiologic attributes of blood transfusion were not based on total community populations. To calculate incidence rates of the transfusion of blood and blood components in the general population and in age-and gender-specific groups, all residents of a United States county who received transfusion(s) from 1989 through 1992 were studied.Study Design and Methods: The study was a prevalence survey (cross-sectional study) of a well-defined population at a specified time.Results: There was no significant change in blood and blood component utilization from the beginning of 1989 through 1992. The incidence of red cell transfusion was 42.88 units per 1000 population per year in both men and women and varied from 12.08 units per 1000 population per year in those less than 41 years old to 245.24 units per 1000 population per year in the group aged more than 65. A random resident's probability of receiving transfusion(s) in any year was 0.89 percent (0.83% for men and 0.94% for women) and varied from 0.26 to 5.17 percent among the three age groups. The incidence of platelet and fresh-frozen plasma transfusion was 21.24 units per 1000 population per year and 8.64 units per 1000 population per year, respectively.Conclusion: Incidence rates of blood transfusion for ''causal'' planning of blood collections are presented here for the first time. The probability of receiving a transfusion of RBCs in any year rises by 20-fold from the rate in those less than 40 years old to that in those more than 65 years old, who receive 53.3 percent of the red cell units transfused.
