RESUMO
【Objective】 To investigate the situation of whole blood collection in Tianjin after COVID-19 prevention and control measures were fully lifted. 【Methods】 The relevant data on whole blood collection of voluntary blood donors in Tianjin 15 days before Spring Festival (2023.01.07-2023.01.21, when China has managed COVID-19 with measures against Class B infectious disease instead of Class A infectious diseases) and 15 days before Spring Festival in 2018 (2018.02.01- 2018.02.15) and 2019 (2019.01.21-2019.02.04) before the breakout of COVID-19 were retrospectively collected and compared. 【Results】 The comparison between the above period in 2023, 2018 and 2019 was as follows: the number of blood donors was 6 124 vs 3 940 vs 4 069; blood collection volume (U) was 9 623 vs 7 378 vs 7 808; the proportion of first-time blood donors, local blood donors and group blood donors was 69.17% (4 236/6 124) vs 65.86% (2 595/3 940) vs 62.05% (2 525/4 069), 59.31% (3 632/6 124) vs 23.27% (9170) vs 18.19% (740/4 069) and 43.42% (2 659/6 124) vs 8.05% (317/2 595) vs 0.15% (6/4 069) (all P<0.05). 【Conclusion】 The adjustment of COVID-19 prevention and control policy has a significant impact on voluntary blood donation, and the corresponding adjustment of blood donor recruitment strategy in blood centers should be conducted to increase the whole blood collection.
RESUMO
【Objective】 To develop and implement a precise and efficient telephone recruitment strategy for apheresis platelet donors based on the information management of blood collection and supply process. 【Methods】 A telephone recruitment strategy based on the whole process information management of apheresis platelet donors (hereinafter referred to as telephone recruitment) was formulated From January 1, 2019, apheresis platelet donors in Hangzhou, registered in the intelligent blood donor recruitment system(hereinafter referred to as the recruitment system), were recruited by telephone calls or (and) SMS reminders to inform re-donation interval, key points of recruitment consultation, blood donation appointment time and other precautions. Response rate, pass rate and blood donation rate of donors before(in 2018) and after( in 2019) the implementation of telephone recruitment, as well as the above three rates during the COVID-19 epidemic in 2020 in Hangzhou were collected and analyzed by χ2 test. 【Results】 The response rate, pass rate, and blood donation rate of apheresis platelet donors in Hangzhou before /after the implementation of telephone recruitment and during the COVID-19 epidemic were 28.52%(3 901/13 678)vs 30.52%(4 429/14 511)vs 39.36%(4 064/10 326), 73.80%(2 879/3 901)vs 77.83%(3 447/4 429)vs 78.20%(3 178/4 064)and 6.77%(2 879/42 553)vs 7.77%(3 447/44 366)vs 8.13%(3 178/39 077, respectively(P<0.05). In 2020, 85.94%(3 178/3 698) of apheresis donors were recruited by telephone(P<0.05). The proportion of apheresis donations successfully recruited by telephone in 2018 and 2019 accounted for 11.74% (2 879/24 519) and 12.48% (3 447/27 628), respectively(P<0.05), contributing 10.59% (4 030 U/38 040 U) and 11.38% (4 875 U/42 853 U) of units(P<0.05) that issued to the clinical. Due to the COVID-19 epidemic, the number of blood donors recruited by telephone and its proportion in 2020 decreased significantly as compared with those before the implementation of telephone recruitment (2019). 【Conclusion】 The telephone recruitment strategy based on the whole-process information management (system) of blood collection and supply can effectively improve the targeted recruitment of apheresis platelet donors and enhance its proportion of apheresis collection that issued to the clinical.
