Determinants of Physician Ordering of Preoperative Autologous Donations

Preoperative autologous donation (PAD) is frequently utilized to reduce infectious disease transmission risks, but it is an expensive form of hemotherapy that is not always closely matched with the needs of the patients. We compared the use of PAD in an academic medical center with patient needs and then investigated the efficacy of a simple intervention to promote targeting of PAD toward patients most likely to benefit from having PADs available. Over a 3‐month period, surgeons whose patients received allogeneic components were asked to complete a questionnaire designed to identify reasons for not ordering PAD. PAD units were used in 14 (11%) of 124 cases, accounting for 6% of perioperative red cell use. The responses (46, 42% of the surveys sent) stated that PAD had not been ordered because of time constraints (39%), medical problems (26%), anemia (15%), and lack of expectation of blood use (24%). Chart review documented the presence of cited conditions in 88% of cases. Logistic and cost concerns were not evident. However, only 8% of the 176 PAD units collected in that period were transfused. Following dissemination of PAD ordering guidelines, this proportion rose to 52% without a reduction in the proportion of elective surgical cases utilizing autologous transfusion. This improvement in ordering practice was maintained over at least in 5‐month period. Thus we were able to improve the efficiency of PAD application (reducing over‐ordering) through a simple feedback to surgeons that assisted them in targeting PAD toward patients most likely to need transfusion.
