虽然已经对献血者进行了流行病学研究，但美国人口接受输血的个体的特征尚未得到很好的描述。受试者来自具有全国代表性的健康与退休研究，其数据与 1991 年至 2007 年的医疗保险档案相关联 (n = 16,377)。进行了一项队列研究，以评估美国老年人随时间的输血频率，并描述血液接受者的特征。 31%（95% 置信区间 [CI]，30%-33%）的美国老年人在 10 年内至少接受过一次输血，5.8%（95% CI，5.4%-6.2%）在 30 天内经历过与输血相关的多次就诊。 10 年间，与输血相关的就诊平均次数为 2.3 次（95% CI，2.2-2.4）。与人口和健康相关因素无关，居住在南方的美国老年人最有可能接受输血（34%），而居住在美国西部的老年人接受输血的可能性最小（26%）。输血的预测因素包括吸烟、低体重指数、癌症病史、糖尿病、终末期肾病和心脏病。非裔美国人和墨西哥裔美国人的血液利用率分别高于其他种族和其他西班牙裔美国人。受教育程度、婚姻状况、宗教信仰和饮酒情况的影响，输血利用也存在差异。输血在美国老年人中很常见。血液使用的区域差异不能仅用患者特征来解释。
While there have been epidemiologic studies of blood donors, the characteristics of individuals who receive transfusions have not been well described for the US population. Subjects were from the nationally representative Health and Retirement Study whose data were linked to Medicare files from 1991 through 2007 (n = 16,377). A cohort study was conducted to assess the frequency of transfusion in older Americans over time and to describe the characteristics of blood recipients. Thirty-one percent (95% confidence interval [CI], 30%-33%) of older Americans received at least one transfusion within a 10-year period and 5.8% (95% CI, 5.4%-6.2%) experienced repeated transfusion-related visits within 30 days. The mean number of transfusion-related visits was 2.3 over a 10-year period (95% CI, 2.2-2.4). Older Americans who lived in the South were most likely to receive a transfusion (34%), independent of demographic and health-related factors, while those who lived in the western United States were the least likely (26%). Predictors of transfusion included smoking, low body mass index, and a history of cancer, diabetes mellitus, end-stage renal disease, and heart disease. African-Americans and Mexican-Americans had greater rates of blood utilization than other races and other Hispanics (respectively). There were also differences in transfusion utilization by education, marital status, religion, and alcohol use. Transfusion is common in older Americans. Regional variations in blood use are not explained by patient characteristics alone.
