Should patients with human immunodeficiency virus infection or chronic hepatitis donate blood for autologous use?
BACKGROUND
The purpose of this project is to formally evaluate the benefits and the risks of allowing patients with human immunodeficiency virus (HIV) infection or hepatitis to donate blood for autologous use.


METHODS
With data on the incidence of transfusion-transmitted hepatitis B virus (HBV), hepatitis C virus (HCV), and HIV; administrative error; and health-care worker exposure, decision analysis was used to quantitate the benefits and risks of autologous blood transfusions versus those of transfusions of blood from allogeneic donors.


RESULTS
Assuming the highest documented probability of transfusion-related infection, the days of life saved by allowing the transfusion of autologous blood to a 30-year-old noninfected or HBV-, HCV-, or HIV-infected patient are 92.52, 70.60, 0.95, and 5.69, respectively. Assuming the lowest documented probability of transfusion-related infection, the days of life saved decrease to 2.96, 2.26, 0.15, and 0.18, respectively. Avoidance of HCV accounts for over 90 percent of the days gained. The days of life lost by other noninfected patients through administrative error average 0.11 in the case of HIV and those lost by health care workers average 0.04, 0.18, and 0.07 in the case of HBV, HCV, and HIV, respectively.


CONCLUSIONS
The benefit of autologous transfusions in patients infected with HBV, HCV, and HIV is significantly less than that in noninfected patients. The risks of this infected blood to other noninfected patients are significant only in the case of HIV-infected blood transfusions; however, there is a measurable risk to health-care workers should all infected blood be allowed into the blood supply.
