“…). In line with previous studies, this study implies that as long as 10°C remains the regulation for transportation of RBC units, the 10°C rule might be more appropriate rather than the time‐based, 30‐min rule . Based on our data, the CT increased more rapidly after 30 min.…”

Background and Objectives The 30‐min rule has been used to maintain a core temperature (CT) of red‐blood‐cell (RBC) units below 10°C during transportation. We evaluated the utility of temperature‐sensitive indicators (TIs) to monitor the surface temperature (ST) of RBC units and to explore whether TIs can help with compliance with the 30‐min rule by extrapolating or correlating temperature change with time. Materials and Methods Two US FDA‐approved TIs, Safe‐T‐Vue 10 (STV10; Temptime Corporation, Morris Plains, NJ, USA) and Timestrip Blood Temp 10 (BT10; Timestrip UK Ltd, Cambridge, UK), were attached to 50 RBC units. After issue, their colour change indicating 10°C was monitored, and temperature excursions were measured by standard reading. In additional 18 RBC units, both ST and CT were monitored simultaneously. Results In 50 RBC units, 94% of STV10 and 100% of BT10 showed colour change indicating 10°C within 30 min; 4% of STV10 and 18% of BT10 showed it during transportation. The time for colour change indicating 10°C differed significantly between STV10 and BT10 (19·0 vs. 5·6 min, P < 0·001). In additional 18 RBC units, 83·3% of STV10, 100% of BT10 and 88·9% of CT reached 10°C within 30 min, and the time for colour change indicating 10°C was 24·4 min in STV10, 14·6 min in BT 10 and 24·2 min in CT (P < 0·001). Conclusion In two TIs, the time for colour change indicating 10°C varied considerably. To enhance the utility of TIs, further improvement and standardization would be needed.

Logistical and safety implications of temperature‐based acceptance of returned red blood cell units

Abstract: 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.
