As a small hospital that does not use transport containers or floor refrigerators, would it be better to just dispose of returned units? They are not allowed to store units outside of the lab, and must be ready to infuse before getting the blood. If the unit is left at room temp. they probably are too warm very quickly. The unit return rate is less than 2 per year. Should we just not re-issue, to avoid having to verify the temp of the unit?
