目的分析广州地区三种主要无偿献血来源及其合格率的变化趋势,为优化釆血来源,提高血液采集质量提供对策。方法收集广州地区2010-2015年自愿无偿献血者全部献血资料,采用Joinpoint回归进行不同献血来源占献血总例的比例及其检测合格率的趋势分析。结果 2010-2015年广州地区自愿无偿献血中,互助献血比例呈显著上升趋势,由2010年的0.67%上升至2015年的5.22%,年均变化率(Annual Percent Change,APC)为50.6%(95%CI:0.3%-126%);个人献血比例显著下降,由56.53%降至46.4%,年均变化率为-4.4%(95%CI:-5.0%--3.7%);团体献血比例有所上升,但年均变化率未达显著水平(APC=1.3%,P>0.05)。血液质量方面,团体献血与个人献血的合格率呈逐年上升,分别由2010年的95.65%、94.41%上升至2015年的97.3%和96.65%,合格率变化差异有统计学意义;互助献血的合格率在90.69%-98.08%之间波动,无明显变化趋势。结论近年来广州地区团体和个人献血者的检测合格率呈上升趋势,但是献血人次增长缓慢,特别是个人献血者逐年减少导致采供血矛盾突出,亟需采取相应措施增加血液供应。
Objective To analyze the source of three main types of unpaid blood donation in Guangzhou and the trend of its passing rate, and provide a countermeasure for optimizing the source of bloodstain and improving the quality of blood collection. Methods The blood donation data of voluntary blood donors from 2010 to 2015 in Guangzhou area were collected. Jointing regression was used to analyze the proportion of donated blood donors in total blood donation and the trend of the detection rate. Results Among the volunteer blood donations in Guangzhou during 2010-2015, the proportion of blood donation increased significantly from 0.67% in 2010 to 5.22% in 2015 with an annual rate change (APC) of 50.6% (95%) % CI: 0.3% -126%). The proportion of donors dropped significantly from 56.53% to 46.4% with an average annual rate of change of -4.4% (95% CI: -5.0% -3.7% But the annual average rate of change did not reach significant level (APC = 1.3%, P> 0.05). In terms of blood quality, the passing rate of blood donation and blood donation increased from 95.65% and 94.41% respectively in 2010 to 97.3% and 96.65% in 2015, with a significant difference in the passing rate; Rate between 90.69% -98.08% fluctuations, no significant change trend. Conclusion The passing rate of blood donors in groups and individuals in Guangzhou is on the rise in recent years. However, the number of blood donors has been increasing slowly. In particular, the number of individual blood donors declines each year, resulting in the contradiction between blood collection and supply. Therefore, it is urgent to take corresponding measures to increase the blood supply.
