METHODS: The utilization of platelets including SDPs was analyzed by mail survey from 33 hospitals and by statistical yearbooks of KRC, 2000. The necessity of SDPs and supplementary amounts of SDP in case of need was estimated. RESULTS: Total 483,611 units of platelets (692-80,414 units) and 12,150 units of SDP(0-3364 units) were utilized by 33 hospitals participated mail survey. The mean discard rate of platelets in the 33 hospitals was 1.5% (0%-15%). The total amounts of SDP collection in 19 hospitals among them were 10,031 units. About one third of 29 hospitals investigated, call for to use 100% of SDPs for patients. And most of the hospitals were cooperative using SDPs supplied from KRC. The amounts of SDP used in Big 5 hospitals, which is located in Seoul was 76.1% of total SDPs used in Korea. CONCLUSION: The relevant amount of supplied SDPs would be 80.000 unit/year, which is 50% of total supplied platelets by KRC. Efficient utilization of SDPs needs well organized collection, SDP stock control and supply system by regional groups of KRC blood center.
