Application of intelligent voice call technology in the recall of lapsed blood donors / 中国输血杂志

ABSTRACT

【Objective】 To analyze and evaluate the application of intelligent voice call technology (IVCT) in the recall of lost blood donors, so as to provide references for the intelligent development of blood donor recruitment. 【Methods】 SMS, human telephone and IVCT were used to recall the lost blood donors from 2016 to 2018, and the recall results were statistically analyzed. 【Results】 20 406 blood donors were recalled from August 20 to December 30, 2020 through 1 029 human telephones, 7 571 automated calls, and 11 806 SMSs, and 4.81%(32/665), 3.44%(51/1 484) and 1.17%(138/11 806) of them responded. There was no significant difference in the recall effect between human telephones and automated calls. The one-year-lapsed blood donors responded about 3 times of those lapsed for 2~4 years (5.97/2.02). 【Conclusion】 The application of IVCT can make up for the shortages of high demand, much interference and long time consuming of human telephones, reduce the labor intensity, improve the efficiency of blood donor recruitment, and promote the recall of lapsed blood donors.
