目的了解部分固定采血屋(点)2013年度人流量变化趋势,为新建固定采血屋(点)选址及合理调整献血服务时间提供科学参考依据。方法选取具有不同位置特征的固定采血屋(点),分时段计数双向人流量,分别统计各测量点、不同时段平均人流量,并采用SPSS17.0软件进行统计学分析。结果对各测量点人流量进行方差分析,按检验水准a=0.05,发现不同测量点月均人流量不同,同一测量点不同时段人流量也不同,P<0.05,差异具有统计学意义;同一测量点,不同月份人流量无明显差异,P>0.05。通过对不同测量点月均人流量进行Dunnett T3两两比较发现:火车站测量点月均人流量最大,新密市测量点月均人流量最小;通过对同一测量点不同时段人流量进行LSD两两比较发现:同一测量点,11:30~12:30、13:30~14:30时段人流量高于其他几个时段。结论新的固定采血屋(点)建设前,应该充分考虑选址位置特点,认真开展人流量调查和分析,并结合人流量变化趋势调整献血服务时间,确保新建固定采血屋(点)能够高效运转,长效满足区域内群众献血需求。
Objective To understand the trend of population flow in some fixed blood collection centers (spots) in 2013 and provide scientific reference for setting up a new fixed blood collection site (point) and adjusting the time of blood donation service reasonably. Methods Fixed blood collection rooms (points) with different location characteristics were selected. Bidirectional human traffic was counted in different time periods. The average traffic volume at each measuring point and different time periods was calculated and analyzed by SPSS17.0 software. Results The ANOVA was used to analyze the flow of people at each measuring point. According to the test level of a = 0.05, it was found that the monthly mean flow of people at different measuring points was different, and the flow of people at the same measuring point was also different at different time points, with statistical significance Point, no significant difference in the flow of people in different months, P> 0.05. Through the Dunnett T3 pairwise comparison of the monthly mean flow of people at different measuring points, it is found that the monthly average flow rate at the measuring point of the railway station is the maximum, and the monthly average flow rate at the measurement point of Xinmi City is the smallest. By LSD two Two comparison found: the same measurement point, 11: 30 ~ 12: 30,13: 30 ~ 14: 30 period of human traffic is higher than the other several periods. Conclusions Before the construction of new fixed blood collection center (point), we should give full consideration to the characteristics of the location of the site, conscientiously carry out the investigation and analysis of the flow of people, and adjust the time of blood donation service according to the trend of the flow of people to ensure that the new fixed blood collection room , Long-term meet the blood donation needs of people in the region.
