摘要
目的寻找影响采血量的关键因素,建立数学模型,为采供血工作提供指导和保障。方法以2015年中国输血协会《全国采供血工作情况调研》中的数据为基础,用SPSS软件对全国325个采供血机构的采血量与宣传经费、纪念品经费、固定献血者数量、献血设施数量、职工人数、财政拨款等指标作相关性分析,建立单因素线性方程,筛选关键影响因素,建立多元线性回归方程。结果采血量与上述各项指标均呈现明显相关(r>0.5),线性关系显著(P<0.01);在与采血量相关的各项指标中,除"固定献血点数量"外的7项指标均为采血量的关键影响因素,协同影响采血量,关系模型为:y=0.062x_1+0.019x_2+0.148x_3+0.221x_4+0.005x_5+0.036x_6+0.007x_7-2.76。结论采供血机构只有对与采血量相关的各项指标科学分析和充分利用,才能逐步走出采供血工作的困局,切实做到保障血液的充足供应。
Objective To screen key influence factors in the amount of blood collection and to establish mathematical models for better guidance and guarantee of blood collection services. Methods The study was based on the＂ Nationwide Blood Collection and Supply Survey＂ that was carried out in 2015 by Chinese Society of Blood Transfusion （CSBT）. Data from 325 services were used to study the correlation between blood collection amount and promotion funds, souvenir funds, regular donor＇s amount, blood collection facilities, regular blood collection sites, work force and financial allocation with software SPSS. Then, linear equations of single factor were established. After screening of the key influence factors, a multi- factorial linear regression equation could be established. Results The blood collection amount was closely correlated with the above factors （ r 〉 0. 5）. The linear relationships were significant （ P 〈 0. 01 ）. 7 of the above factors were the key influence factors in the amount of blood collection except＂ regular blood collection sites＂. They influence the amount of blood collection, coordinately by the model of y = 0. 062X1 ＋ 0. 019x2 ＋ 0. 148x3 ＋ 0. 221x4 ＋ 0. 005x5 ＋ 0. 036x6 ＋ 0. 007x7 - 2. 76. Conclusion In order to overcome the difficult situation in blood collection and supply and guarantee the clinical use of blood, blood collection services must conduct scientific analysis and rational use of these key factors and mathematical models.
