2007-2014年佛山市中心血站单采血小板的临床供应量分析

Analysis of clinical supply of apheresis platelet provided by Foshan Central Blood Station from 2007 to 2014

目的分析广东省佛山市中心血站单采血小板临床供应量的变化趋势，为单采血小板献血者招募及单采血小板采集计划的制定提供数据支持。方法选择本血站2007-2014年发放至本市临床医疗机构的19377个治疗量单采血小板数据为研究对象。采用Excel软件分别绘制其年度、季度及ABO各血型单采血小板临床供应量趋势图；并且计算各年度单采血小板临床供应量环比增长率，以及ABO各血型单采血小板临床供应量增长率。结果①2007-2014年本血站单采血小板临床供应量，从2007年的1527个治疗量上升到2014年的3131个治疗量，增长率为105．0％。其中，2008年临床供应量最低，为1488个治疗量，2013年临床供应量最高，为3148个治疗量。各年环比增长率分别为～2．6％、31．5o,4、34．6％、7．9％、-6．8％、18．8％及-0．5％。②2007-2014年，除2007年和2012年外，其余各年第1季度的单采血小板临床供应量在当年4个季度中均为最低。③2007-2014年，本血站0型单采血小板临床供应量最多，为7972个治疗量，AB型最少，为1113个治疗量。ABO各血型单采血小板临床供应量均呈上升趋势，与2007年相比，2014年A、B、0和AB型单采血小板的临床供应量增长率分别为147．8％、131．3％、62．6％和211．3％。结论2007-2014年佛山市中心血站单采血小板临床供应量呈明显上升趋势，但是存在季度分布不均的情况。采、供血机构需制定合理的单采血小板采集计划，避免季节性血小板供应短缺。

Objective To analyze the trend of clinical supply of apheresis platelet provided by Foshan Central Blood Station in Guangdong Province, in order to provide data support for the recruitment of platelet donors and the collection plan of apheresis platelets. Methods From 2007 to 2014, the data of 19 377 therapeutic doses of apheresis platelet which were provided from Foshan Central Blood Station to clinical medical institutions in Foshan were included in this study. Excel software was used to draw trend chart of annual, quarterly, and each ABO blood group apheresis platelets clinical supply, respectively. And the ring growth rates of annual apheresis platelets clinical supply, as well as the growth rates of each ABO blood type apheresis platelets clinical supply were calculated. Results O From 2007 to 2014, the clinical supply of apheresis platelets increased from 1 527 therapeutic doses in 2007 to 3 131 therapeutic doses in 2014, the growth rate was 105.0%. The lowest clinical supply was 1 488 therapeutic doses in 2008, with the highest clinical supply was 3 148 therapeutic doses in 2013. The ring growth rates were --2. 6%, 31.5%, 34.6%, 7.9%-6.8%, 18.8% and -0.5%, respectively. ②From 2007 to 2014, except for 2007 and 2012, the clinical supply of apheresis platelets in the first quarter of the year was the lowest in the four quarters of each year. ③ From 2007 to 2014, the clinical supply of O blood type apheresis platelets were the largest, reaching 7 972 therapeutic doses, and the least blood type was AB blood type, only 1 113 therapeutic doses. Clinical supply of A, B, O and AB blood type apheresis platelets increased each year, and the growth rates were 147.8%, 131.3%, 62.6% and 211.3% from 2007 to 2014, respectively.Conclusions The clinical supply of apheresis platelets provided by Foshan Central Blood Station is unbalanced greatly from 2007 to 2014, but its distribution is uneven in seasons. Reasonable planning of apheresis platelet collection program by blood services is needed to avoid seasonal platelet shortage.
