Background: Disasters themselves can increase the blood transfusion requirements due to an increase in injuries, and can lead to deficiencies in the blood transport system. To prepare for a disaster, it is important to know the actual blood requirements at the time of the disaster and the changes in blood supply according to the type of disaster.
Methods: From March 2018 to May 2018, all RBC transfusion cases at Pusan National University Yangsan Hospital were analyzed retrospectively. The patients were divided into Categories 1 to 3 according to the urgency of transfusion by disease. Priority one was defined as having only a category 1 patient receiving a transfusion, and priority two was defined as an emergency situation where only category 1 and 2 patients could receive transfusions.
Results: The amount of RBC concentrates used in this hospital was 53.1 units per day, which was 19.4%, 42.2%, and 38.4% in category 1, 2, and 3, respectively. The results of simulating the number of blood products that can be used according to the priorities when having a blood product inventory held by the blood banks are as follows: 2.45 days (normal), 12.64 days (P1), and 3.97 days (P2) can be used.
Conclusion: The simulation showed the time of blood transfusion without additional blood supply in the event of a crisis, and will help establish the transfusion countermeasures in the event of a disaster.
