An Adequate Blood Supply for Queen Sawangvadhana Memorial Hospital, Thai Red Cross Society

Abstract

Objective: To determine an adequate blood supply for Queen Sawangvadhana Memorial Hospital. This knowledge will be used to adjust and maintain invariable blood stock in both insufficient and excess blood supply condition.

Materials and Methods: We collected and analyzed the total number of crossmatch and transfusion units of all blood components from data base in 2009. The average daily, weekly and monthy usage was calculated. A stock of red cell products and fresh frozen plasma are supply for 7 days usage, platelets is supply for 3 days and cryoprecipitate is supply to cover I month usage. The stock level of all blood components included blood for emergency need (10%) and covered the expected growth in use over the past year.

Results: In 2009, there were 9,834 units of red cell products, 3,789 units of platelets, 2,548 units of fresh frozen plasma and 1,729 units of cryoprecipitate released for transfusion. The data of our study showed an increased utilization in 2009 of red cell products, platelets, fresh frozen plasma and cryoprecipitate were 19.1%, 66.9%, 24.7% and 6.4%, respectively. The ideal inventory level of red cell products should be 276 units: 60, 92, 104 and 20 units of blood group A, B, O and AB, respectively. The blood inventory levels of platelets, fresh frozen plasma and cryoprecipitate should be 65, 79, 168 units, respectively. The details of blood components request were used to planning blood components preparation.

Conclusion: The ideal blood inventory levels for our hospital were obtained from this study. The inventory level should be often checked stock counts and evaluated periodically to planning inventory level for next year.
