【Objective】 To investigate the status of blood donation of pregnant women's family members, so as to recruit their family members and establish potential blood donation team. 【Methods】 Questionnaire survey was carried out among family members of pregnant women who participated in blood preparation plan by random sampling. 【Results】 The motivations of self-efficacy, internal reward, severity and stress of blood donors were significantly higher than those of non-donors, but non-donors concerned more about negative feelings of phlebotomy(P<0.05). People with rare blood type, low age, high income, weak negative motivation and strong positive motivation had stronger blood donation intention and higher probability of blood donation behavior(P<0.05). 【Conclusion】 It is necessary to expand blood sources through multiple channels by organizing publicity activities around targeted groups, such as establishing channels for blood donation reservation, taking the lead role of the donated crowd, so as to build up a recruitment team for voluntary blood donation.

【Objective】 To explore the feasibility and necessity of establishing a scheduled blood donation team focusing on pregnant women′s blood preparation by the comparative analysis between RhD positive and negative pregnant women′s family participation in the team, so as to provide basis for decision-making on fine management of key groups of voluntary blood donation. 【Methods】 A questionnaire survey was conducted between the families of RhD negative and positive pregnant women participating in the blood preparation program from January to September 2020 to compare the differences in incentive measures, blood donation cognition, motivation, intention and behavior between the two groups. 【Results】 For common incentive measures for blood donation, both families of RhD negative pregnant women(the former) and families of RhD positive pregnant women(the latter) preferred expectant mothers to use blood first, accounting for 98.02% (99/101) and 98.51% (132/134), respectively, with no significant difference.For other incentive measures, the preference of the former were significantly higher (P<0.05). For the cognition of voluntary blood donation, the awareness of the former was higher than that of the latter, with significant difference(P<0.05), except for clinical blood use expenses; the score of intention to donate blood of the former was higher than that of the latter(P<0.05); among the six factors of motivation to blood donation, the score of severity of the former(understanding of the status of blood supply) was higher than that of the latter, and the difference was statistically significant(P<0.05). Analysis of ROC curve showed that AUC of fitting model of the former and latter was 0.816 (95% CI: 0.731~0.902) and 0.924 (95% CI: 0.871~0.977). 【Conclusion】 Pregnant women families participated in the program are more interested in the incentive measures of health policies.The former has higher awareness of the current supply situation hence demonstrates higher intention to donate blood than the latter.Therefore, relevant policies should be formulated to improve the enthusiasm of pregnant women families to participate in voluntary blood donation, optimize the construction strategy of scheduled blood donation team and expand the donation team while ensuring blood use of pregnant women.
