title: A novel system for providing compatible blood to patients during surgery: "self-service" electronic blood banking by nursing staff.
abstract: BACKGROUND
  A good blood bank must be able to provide compatible blood units promptly to operating room patients with minimal wastage. A "self-service" by nursing staff blood banking system that is safe, efficient, and well-accepted has been developed.
  
  
  METHODS
  Specific blood units are no longer assigned to surgical patients who have a negative pretransfusion antibody screen, irrespective of the type of surgery. A computer-generated list of the serial numbers of all group-identical blood units currently in the blood bank inventory is provided for each patient. The units themselves are not labeled with a patient's name. The group O list will be provided for group O patients, the group A list for group A patients, and so forth. Should the patient require transfusion during surgery, the operating room nurses go to the refrigerator, remove any group-identical unit, and check the serial number of the unit against the serial numbers on the patient's list. If the serial number is on that list, the blood bank will accept responsibility for compatibility. The system was implemented in 1995.
  
  
  RESULTS
  Since implementation, a total of 2154 patients have undergone operations at this hospital. Thirty-two patients received more than 10 units of red cells each. There were no transfusion errors. The crossmatch-to-transfusion ratio was reduced from 1.67 to 1.12. Turnaround time for supplying additional or urgent units to patients in operating room was shortened from 33 to 2.5 minutes. There was no incidence of a blood unit's serial number not being on the list. Work by nurses and technical staff was reduced by nearly 50 percent.
  
  
  CONCLUSIONS
  The "self-service" (by nursing staff) blood banking system described is safe and efficient. It saves staff time and can be easily set up.
