We compared predeposit autologous blood utilization practices in 612 hospitals (where 107,559 autologous and 2,504,522 homologous units were transfused in all of 1989). Participating blood bankers prospectively followed up donors who presented for initial donation during an 11-week period in early 1990. They recorded the number of autologous donors whose blood was drawn (n = 22,276); units that were donated (n = 40,163), transfused (n = 23,988), crossed over (n = 937), and discarded (n = 15,443); and donors transfused with autologous blood only (n = 11,923) or donors who received homologous blood (n = 2002). Most donors (89.7%) avoided homologous blood, including donors (39.5%) who did not require transfusion. Units that were donated for low-risk surgery represented 23.1% of all units that were collected, and the rate of donation for these procedures was directly proportional to the percentage of donors who did not require transfusion and to the discard rate. We concluded that a major focus of quality improvement in autologous transfusion practice should be the reduction of donations for surgical procedures for which blood replacement is rarely needed. |
