Objective: To establish level of adequate blood supply for Siriraj Hospital. This information
will be used as a guide to arrange and maintain continuous blood supply in both shortage and surplus
situation. Materials and Methods : We determined the total use of blood component for each blood
type over 3 months period (October to December 2006). The average daily use was calculated and
multiplied by seven to estimate weekly usage for red cells and fresh frozen plasma (FFP) as our goal
of inventory. Our goal for platelets, which has only 5 days shelf-life is supply to cover three days use.
The stocking level of cryoprecipitate is based on maximum demand per week. Ten percent addition
of all products are calculated to cover emergency need. Results: During October to December 2006,
there were 11,459 units of red cells, 8,600 units of platelets, 4,632 units of fresh frozen plasma (FFP)
and 2,654 units of cryoprecipitate released for transfusion. The ideal inventory levels of blood component
group O, A, B, AB were : for red cell products : 378, 208, 308 and 62 units respectively, for platelets: 132,
59, 99 and 20 units respectively, for FFP : 146, 77, 123 and 31 units respectively. The ideal inventory
level for cryoprecipitate was 561 units. The details of blood product demand were also obtained and
can be benefit to guide our blood component production. Conclusion : The ideal inventory levels were
obtained from this study. This will provide adequate supplies of blood product for routine and emergency
condition in our institute. To increase precision, the ideal inventory level should be evaluated
periodically and need to be adjusted whenever a change is observed.
