Abstract

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.
