National Blood Collection & Utilization Survey
The U.S. Department of Health and Human Services (HHS) 2011 National Blood Collection and Utilization Survey Report (NBCUS) provides statistics on the collection and transfusion of blood from the entire calendar year 2011, identifies trends and compares current findings with those of the six previous nationwide NBCUS surveys conducted since 1998.
According to the 2011 NBCUS report, the supply of available allogeneic whole blood, or WB, and red blood cell, or RBC, units, after accounting for test discards, was nearly 14.5 million units in 2011, which is a statistically significant decrease of 9.1 percent compared with the supply of allogeneic WB and RBCs in 2008. The 2011 report explains that, over the past several years, blood collectors have made adjustments to correct the oversupply of WB and RBCs that was identified in the 2009 survey report. Additionally, transfusions of WB and RBCs declined significantly by 8.2 percent to 13.8 million units. The blood supply was provided by more than 9 million allogeneic donors — 31 percent of whom were first-time donors and 69 percent of whom had donated previously. A total of 20.9 million components were transfused, including WB, RBCs, platelets, plasma, cryoprecipitate and granulocytes, representing a decrease of 11.6 percent compared with transfusions in 2008. Providing new national-level information on an emerging blood safety initiative, thirty percent of 2011 hospital respondents indicated that patient blood management (PBM) is now a formal program in their establishments."
