Description:Introduction:
Previous iterations of National Blood Collection and Utilization Survey (NBCUS) have demonstrated declines in blood collection and transfusion in the United States since 2008, including declines of 3.0% and 6.1% in red blood cell (RBC) collections and transfusions between 2015 and 2017, respectively. This study describes results of the 2019 NBCUS.
Methods:
The survey was distributed to all US blood collection centers, all hospitals performing ≥1000 surgeries annually, and a 40% random sample of hospitals performing 100–999 surgeries annually. Weighting and imputation were used to generate national estimates for units of blood and components collected, distributed, transfused, and outdated.
Results:
In 2019, 11,590,000 RBC units were collected (95% confidence interval [CI], 11,151,000–12,029,000 units), a 5.1% decrease compared with 2017, while 10,852,000 RBC units were transfused (95% CI, 10,444–11,259 units), a 2.5% increase from 2017. Between 2017 and 2019, platelet distributions (2,508,000 units; 95% CI, 2,375,000–2,641,000 units) decreased by 2.0%, and plasma distributions (2,679,000 units; 95% CI, 2,525,000–2,833,000 units) decreased by 16.5%. During the same time period, platelet transfusions (2,243,000 units; 95% CI, 1,846,000–2,147,000 units) increased by 15.8% and plasma transfusions (2,185,000 units; 95% CI, 2,068,000–2,301,000 units) decreased by 8.0%.
Conclusion:
Utilization of RBC in the United States might have reached a nadir. Between 2017 and 2019, RBC collections declined while RBC transfusions did not significantly change, suggesting a narrowing between blood supply and demand. Monitoring national blood collection and utilization data is integral to understanding trends in blood supply safety and availability.
