When you use extended sample expiration, how does this affect electronic crossmatch? The sample collection date would cause our LIS to reject the EXM rule. Do you just perform IS serological crossmatches?

Our LIS is set up to allow an EXM for PAT specimen outdates of 14 days if the patient qualifies for EXM.

Cerner allows us to extend the date of the Preassess sample. If no pregnancy or transfusions, and a prior history or second sample drawn for confirmation of ABO/Rh, sample good for 4 days with OR day being day one. Not to surpass 30 days sample date. EXM still applies when sample date is extended.

Fill out and sign form during sample collection. Phlebotomist is responsible the form is filled out. Patient label goes in box, patient ticks boxes to transfusion and pregnant questions with yes / no option, signs at bottom. Form goes to BB and is then scanned into record.

That's what we have been doing but we are wondering if we have to keep the signature in the permanent record.  We were planning to go to an electronic documentation process and then there would be no signature.  Is it any different from asking a patient for drug allergies and recording them?  They don't sign for that.

We used 14 days. We chose that number mainly because of specimen storage space. Preadmit nurses were required to ask and document the recent transfusion and pregnancy questions in the computer on all their patients. These showed on the blood bank requisitions from preadmit and had to be answered “no” to extend the specimen. Patients signed an overall form regarding the accuracy of their history and that was part of it. Years ago, we once had an autologous unit on the shelf for a patient and the ”transfused in last 3 months” question was answered “yes”. On checking, we learned the patient lived in another state, had a unit of autologous blood drawn when he had a doctor’s appointment in our city, had returned home, and gotten a transfusion there before the surgery.

We extend it to 7 days but are considering extending it to 15. The transfusion questions are answered by the ordering physician concerning prior transfusion and pregnancies. Antibody hx is established when the screen is completed. If positive, we require a recollect on day of surgery.

We also recollect the day of surgery, but don't test unless we need to set up units that day.
