Abstract
Objectives To understand the clinical blood supply at provincial and city level in China.Methods The questionnaire of blood supply was designed by Chinese Society of Blood Transfusion.The blood supply of blood products including whole blood,red cells,platelets,plasma,cryoprecipitate and leukocyte concentrates were included in this questionnaire.Questionnaires were distributed on July 1st,2015 by the official website of Chinese Society of Blood Transfusion (www.csbt.org.cn).Blood collection services at provincial and city level should fill in and submit before Aug 31.Information according to the questionnaire were collected and sorted out with Excel 2007 by staffs of Blood Donation Promotion Committee of Chinese Society of Blood Transfusion.The valid data were analyzed with SPSS 19.0.Results The effective rate of this survey was 100 ％ (350/350).The annual clinical blood supply (10 000 U) in blood collection services on provincial and city level in 2012-2014:the blood supply of whole blood and red cells were 1 864.47,increased to 1 898.58 by 1.83％ (34.11/1 864.47) compared with 2012 and increased to 1 965.88 by 3.54％ (67.30/1 898.58) compared with 2013,respectively.The apheresis platelets were 97.41,increased to 112.96 by 15.95％ (15.54/97.41) compared with 2012,and increased to 124.08 by 9.85％ (11.13/112.96) compared with 2013,respectively.The plasma were 2 752.93,increased to 2 765.76 by 0.47％ (12.82/2 752.93) compared with 2012,and increased to 2 830.75 by 2.35％ (64.99/2 765.76) compared with 2013,respectively.The cryoprecipitate were 165.39,increased to 189.13 by 14.35％ (23.74/165.39) compared with 2012,and increased to 236.65 by 25.12％ (47.52/189.13) compared with 2013,respectively.The leukocyte concentrates were 2.33,increased to 3.11 by 33.55％(0.78/2.33) compared with 2012,and reduced to 2.18 by 29.71％ (0.92/3.11) compared with 2013,respectively.The WB-derived platelet concentrates were 56.30,reduced to 48.45 by 13.93％ (7.84/56.30) compared with 2012,and reduced to 44.23 by 8.73％ (4.23/48.45) compared with 2013,respectively.There were differences in the blood products between blood centers and center blood stations.The blood centers mainly provided red blood cells in additive solution and fresh-frozen plasma,while the center blood stations mainly provided leukocyte-reduced red blood cells in additive solution and methylene blue-treated and removed frozen plasma.The large differences in rates of blood supply between regions were evident.The rates of blood supply of whole blood and red blood cells,apheresis platelets,plasma,and cryoprecipitate in regions in 2014 (Units/10,000population):Northeast region were 150.36,9.22,228.86 and 18.33 respectively;South China were 150.87,9.68,142.20 and 35.35;North China were 166.28,14.02,183.34 and 7.45;Central China were 152.64,9.32,125.94 and 21.25;East China were 139.73,10.18,285.30 and 17.92;Northwest were 144.85,5.80,137.36 and 8.71;Southwest were 115.87,3.51,240.80 and 9.45.Conclusion This survey suggests a steady increasing trend of blood supply in China.China still faces many challenges in blood supply in the future.关键词
