Abstract
BACKGROUND
AABB requires that red blood cells (RBCs) are maintained at 1 to 10°C during transport. Historically, blood banks used the 30-minute rule for returned RBCs transported outside of validated containers. The implications of this policy have not been previously reported in a real-life hospital setting.
STUDY DESIGN AND METHODS
A 2-year, retrospective review of RBC units returned outside of qualified containers was conducted. During the first year, the 30-minute rule was used to accept RBCs back into inventory. Sequentially, the following year, a temperature-based approach was implemented using a thermometer with an accuracy of ±1°C. Time out of the blood bank, temperature upon return, wastage, and transfusion reactions associated with the reissued RBCs were analyzed.
RESULTS
In our practice, the 30-minute rule would have accepted 15.2% of RBC units outside of the allowed temperature. Compared to the 30-minute rule, temperature-based acceptance was associated with a 13% increase in wastage (p < 0.001). During the 30-minute rule period, transfusion of returned and subsequently reissued RBCs was associated with a nonsignificant trend toward a higher transfusion reaction rate compared to the overall RBC transfusion reaction rate (1.4% vs. 0.6%, p = 0.084). During the temperature period, transfusion of returned and subsequently reissued RBCs had the same transfusion reaction rate compared to the overall RBC transfusion reaction rate (0.5% vs. 0.5%, p = 1.0).
CONCLUSION
Temperature-based acceptance of returned RBCs is associated with significantly higher wastage compared to the 30-minute rule. A temperature-based acceptance practice mitigates the risk of accepting RBCs with unacceptable temperatures returned within 30 minutes of issue.
