The National Blood Collection and Utilization Survey (NBCUS) has demonstrated declines in blood collection and transfusion in the United States since 2008, including declines of 11.6% in red blood cell (RBC) collections and 13.9% in RBC transfusions during 2013-2015. This study described the 2017 NBCUS results.
The 2017 NBCUS was distributed to all US blood collection centers, all hospitals performing at least 1000 surgeries annually, and a 40% random sample of hospitals performing 100 to 999 surgeries annually. Weighting and imputation were used to generate national estimates for units of blood and components collected, deferred, distributed, transfused, and outdated.
Response rates for the 2017 NBCUS were 88% for blood collection centers and 86% for transfusing hospitals. Compared with 2015, the number of RBC units collected during 2017 (12,211,000; 95% confidence interval [CI], 11,680,000-12,742,000) declined by 3.0%, and transfused RBC units (10,654,000, 95% CI, 10,314,000-10,995,000) declined by 6.1%. Distributed platelet (PLT) units (2,560,000; 95% CI, 2,391,000-2,730,000 units) increased by 5.1%, and transfused PLT units (1,937,000, 95% CI, 1,794,000-2,079,000) declined by 2.3%. Distributed plasma units (3,209,000; 95% CI, 2,879,000-3,539,000) declined by 13.6%, and transfused plasma units (2,374,000; 95% CI, 2,262,000-2,487,000) declined by 12.9%.
The 2017 NBCUS suggests a continued but slowing decline in demand for RBCs. The decline in blood collection and use will likely continue. Despite decreasing demand and increasing manufacturing costs of blood products, the US blood industry has met the regular and emergent needs of the country.
自 2008 年以来，美国的国家血液采集和利用调查（NBCUS）显示血液采集和输血量下降，2013-2015 年期间，红细胞（RBC）采集量下降 11.6%，RBC 输注量下降 13.9%。本研究描述了 2017 年 NBCUS 的结果。
2017 年 NBCUS 分发给所有美国血液采集中心、每年至少进行 1000 例手术的所有医院，以及每年进行 100-999 例手术的医院的 40%随机样本。使用加权和插补来生成血液采集和采集、推迟、分发、输注和过期的血液和成分的全国估计数。
2017 年 NBCUS 的回复率为血液采集中心的 88%和输血医院的 86%。与 2015 年相比，2017 年 RBC 单位采集量（1221.1 万单位；95%置信区间[CI]，1168 万单位-1274.2 万单位）下降了 3.0%，RBC 输注单位（1065.4 万单位，95%CI，1031.4 万单位-1099.5 万单位）下降了 6.1%。分发的血小板（PLT）单位（256 万单位；95%CI，239.1 万单位-273 万单位）增加了 5.1%，PLT 输注单位（193.7 万单位，95%CI，179.4 万单位-207.9 万单位）下降了 2.3%。分发的血浆单位（320.9 万单位；95%CI，287.9 万单位-353.9 万单位）下降了 13.6%，PLT 输注单位（237.4 万单位；95%CI，226.2 万单位-248.7 万单位）下降了 12.9%。
2017 年 NBCUS 表明 RBC 的需求持续下降，但速度正在放缓。血液采集和使用量的下降可能会继续。尽管血液制品的需求下降和制造成本增加，但美国的血液行业已经满足了国家的常规和紧急需求。
