Supplementary notes

Data is from the National Blood Collection and Utilization Survey (NBCUS).
The 2019 NBCUS "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. The response rates for the 2019 NBCUS were 94.3%(50/53) for community-based blood collection facilities, 84% (76/90) for hospital-based blood collection facilities, and 76% (2140/2808) for transfusing hospitals."
* Donors deferred for low hemoglobin included those that do not meet the current FDA blood hemoglobin level requirements for blood donation.
** Other medical reasons may include the use of medications on the medication deferral list, growth hormone from human pituitary glands, Hepatitis B Immune Globulin (HBIG), unlicensed vaccines, or presenting with physical conditions or symptoms that do not qualify a person to be a blood donor.
*** High-risk behavior deferrals include deferrals intended to reduce the risk of transmission of infectious diseases including HIV and hepatitis viruses. Examples of questions intended to identify these risks are sexual contact (men who have sex with men [MSM]) and non-medical injection drug use questions.
^ Travel deferrals are deferrals for travel to a specific region of the world.
