固定献血者活动对广州地区固定献血者保留的效果分析

The effectiveness of regular blood donor activities on the retention and operation of regular blood donors in Guangzhou

目的分析广州血液中心固定献血者活动对街头固定献血者的保留效果。方法 2015年10月—2017年9月,对收到活动邀请广州血液中心登记在册的街头固定献血者67 233人统计分析其后续献血情况,结合广州血液中心信息系统的献血者性别年龄等人口学信息,以收到活动邀请后献血为有效保留组,未献血为对照组,进行Logistic回归分析,固定献血者活动对街头固定献血者的保留效果及活动后再次献血的相关因素。结果 67 233位固定献血者中,受邀参与活动组的固定献血者有效保留率(献血组人数/总人数)高于受邀但未参加活动组[OR=2.752,95%CI(2.334,3.245)],其中25—34岁[OR=1.412,95%CI(1.120,1.779)],35—44岁年龄段[OR=2.326,95%CI(1.805,2.998)],既往献血次数10次以下[OR=9.309,95%CI(7.690,11.268)]的街头固定献血者,在收到活动邀请后更倾向于再次献血。结论广州血液中心固定献血者活动显著提高街头固定献血者的有效保留率。针对既往献血≥10次,18—24/45岁及以上街头固定献血者,需要进一步探索更有效的激励方法。

Objective To analyze the effectiveness of regular blood donor activities on the retention of regular blood donors in Guangzhou. Methods From October 2015 to September 2017, 67 233 regular donors donated blood on the street in Guangzhou Blood Center were invited to participate in the regular blood donor activities through messages, their following donation behavior were analyzed combined with their demographic information in the Information System through Logistic regression between post-activity blood donation(effective operation) and no donation(control) performed using SPSS 24. The factors related to the effective retention of regular blood donors through the activities and post-activity donation behavior were analyzed. Results Among the 67 233 donors, the effective retention rate of regular blood donors inthe participating group(the number of post-activity blood donors/total) was higher than that of the non-participating group [OR=2.752, 95% CI(2.334, 3.245)], regular donors aged25—34[OR=1.412, 95% CI(1.120, 1.779)], or 35—44[OR=2.326, 95% CI(1.805, 2.998)], or with less than 10 previous donations[OR=9.309, 95%CI(7.690, 11.268)] are more likely to donate blood again after the activities. Conclusion The regular blood donor activity in Guangzhou significantly improved the effective retention rate of street regular blood donors. More effective retention methods are needed fordonors aged18—24 or 45 or above, donors with10 times or more previous donations.
