Motivation, intention and behavior of prenatal blood donation between families of RhD negative and positive pregnant women: A comparative study / 中国输血杂志

ABSTRACT

【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.
