Summary
Preoperative autologous blood donation (PABD) successfully helped patients avoid transfusions, but its utility decreased over time due to declining use and frequent single-unit transfusions.
Area of Science:
- Transfusion Medicine
- Surgical Patient Blood Management
Background:
- Preoperative autologous blood donation (PABD) is a strategy to reduce allogeneic blood transfusions in elective surgeries.
- Transfusion practices have evolved, necessitating an evaluation of PABD program effectiveness.
Purpose of the Study:
- To analyze blood utilization trends within the Héma-Québec PABD program from 1993 to 2000.
- To assess the changing utility of PABD in major elective surgeries.
Main Methods:
- Prospective data collection on blood donation, transfusion, surgery type, and demographics for PABD participants.
- Computerized database management for Héma-Québec PABD program participants.
Main Results:
- Autologous donations decreased by 26% after 1995, comprising 0.8-2% of total collections.
- Utilization rates for PABD declined significantly across major procedures (e.g., radical prostatectomy, knee/hip replacement, scoliosis) between 1993 and 2000.
- While 85-95% of patients avoided allogeneic transfusions, 18% received single-unit autologous transfusions in 2000, indicating reduced PABD efficiency.
Conclusions:
- PABD remains effective in helping patients avoid allogeneic transfusions.
- Declining utilization rates and increased single-unit transfusions suggest a diminishing role for PABD over time.
