A study of an educational intervention to decrease inappropriate preoperative autologous blood donation: its...

Area of Science:

• Transfusion Medicine
• Surgical Patient Blood Management

Background:

• Overcollection of preoperative autologous blood is a persistent challenge in healthcare.
• Effective strategies are needed to reduce unnecessary autologous donations.

Purpose of the Study:

• To evaluate an educational intervention's impact on preoperative autologous blood donations.
• To assess the effect of reduced donations on subsequent transfusion rates.

Main Methods:

• A didactic presentation and written materials on autologous blood risks were provided to gynecology staff and patients.
• Donation rates, units collected, and transfusion rates were measured before and after the intervention for elective hysterectomy patients.

Main Results:

• The proportion of patients donating autologous blood dropped from 53% to 26% (p<0.01).
• Average units collected per patient decreased from 0.86 to 0.31 (p<0.01), saving 80 donations annually.
• Overall transfusion rates fell from 10% to 3.7% (p=0.03) without altering allogeneic transfusion rates.

Conclusions:

• Physician and patient education effectively reduces unnecessary preoperative autologous blood donations.
• Lowering unnecessary donations decreases autologous transfusion rates and associated risks.
• This approach does not increase the risk of allogeneic transfusions.
