We also have Meditech but can't count on the admitting department correctly entering everything in for an accurate audit trail. If any identifying information changes (name, MRN, DOB), admitting MUST call the blood bank before changing. If there is a blood bank specimen, we do an armband verify where a blood bank staff member physically watches the old armband being removed, comparing to the current specimen and watching the new armband being reapplied with a corresponding new label attached to the specimen. If we find an armband has been changed or records have been merged without contacting the blood bank, we start all over with a new specimen. If it is an emergent situation, they now get uncrossmatched O=.
