成都地区采供血现状调查及未来趋势分析

Investigation of blood collection and supply in Chengdu from 2000 to 2006

目的通过对成都地区血液采集供应现状调查,分析和预期本地区采供血总体发展趋势。方法对2000—006年成都地区血液采集量、成分分离量、血液传染指标阳性率、临床用血量与成都市人口和医疗机构床位数进行统计,用相关和逐步回归法进行数据分析。结果本地区血液采集平均逐年增长率约为17.74%;成分血分离逐年递增率:红细胞分离率由27.4%增加到84.55%,机采血小板年采集量逐年平均增长率为38.00%;临床成分输血率逐年增长,全血使用逐年下降;年用血量与全市人口数存在线性关系(γ=0.997,P<0.001);人均用血量与全市人口存在线性关系(γ=0.998,P<0.001)。结论随着经济发展、人口增加、医技水平的提高,血液的用量按照一定的比例持续增长,因此继续做好无偿献血工作,确保血液安全有效供应将是血站一项长期而艰巨的任务。

Objective To investigate the blood collection and supply in Chengdu, from 2000 to 2006, and also to analyze its development tendency. Methods The volume of blood collection, blood component preparation, the positive rate of blood screening, the volume of clinical consumption, as well as the population statistics and bed numbers in medical institutions and hospitals, from 2000 to 2006, were reviewed. Correlation and coefficient of regression were used for the statistical analysis. Results The annual average rate of growth （AARG） of blood collection and supply is 17.74%. The rate of RBC separation increased from 27.4% % to 84.55%, and the AARG of phtelet apheresis product was 38.00%. Blood components had become much more popular than whale blood in clinical application. There was a good linearity correlation between the blood provision and the population statistics （γ= 0.997, P 〈 0. 001 ）, as well as between the average blood consumption and the population statistics （γ= 0.998, P 〈 0.001 ）. Conclusion Along with the development of economy, the growth of population, and the improvement of medical care, blood consumption will increase continually. Therefore, in order to assure safe and effective blood supply, voluntary donation should be consistently advo- cated.
