I am at a Michigan hospital that also has changed to standardized armband colors. We were using red blood bank armbands (pre-admit and inpatients alike) but was told we needed to change our armband color. Yes, our hospital armbands are white also. We now use green blood bank armbands. I am told that blood bank armbands have not been assigned a designated color, but red was taken by something else (allergies maybe, I don't recall). At our facility, before we put a blood bank armband on a pre-admit patient, they have a white hospital armband put on by the registration staff. When we have the need for an armband to be removed the person removing the band is asked to first contact the blood bank. We then send them a new band along with an audit trail form. At this point they can cut off the armband, complete the new band and place it on the patient. The form is a fill in the blank something along the lines of: "I, _____________, removed blood bank armband # ________ and replaced it with blood bank armband # ________ for __________________(patient name and medical record #) on _________ (date/time)". They must then return this form to blood bank immediately so we may update our records. Good Luck!
