BackgroundThe Hunter Area Pathology Service provides transfusion services to 4 metropolitan and 11 rural hospitals in Australia. To improve blood availability, conserve blood stocks, and reduce crossmatch-to-transfusion ratios, a networked electronic blood release system (EBRS) has been developed for computer cross-matching within the laboratory and at sites remote from the transfusion laboratory. It is innovative, in that non-laboratory staffs have been trained to release computer-matched blood at remote hospitals without transfusion laboratories.Study Design And MethodsThe EBRS software was tested and validated according to the Australian software standards AS 3563.1 and 3563.2 (1991). Over 7000 units were released by the EBRS in a laboratory trial conducted in conjunction with the conventional immediate-spin crossmatch. A further, 12-month study was conducted within the laboratory before the staged implementation of the EBRS at the remote hospitals.ResultsThe EBRS has resulted in 1) a 25-percent reduction in the number of units requested by the medical staff, resulting from the reduction in time needed to provide compatible blood due to the elimination of the serologic crossmatch; 2) better blood stock management (reducing outdated red cell units by 30%); and 3) significant savings in laboratory workload (savings of approximately 100 hours/month). In addition, the rapid availability of computer-crossmatched red cells in emergency situations has enhanced patient safety.ConclusionThe EBRS is a safe and efficient means of providing red cells within the laboratory and at remote hospitals without laboratory services.
