Factors associated with bone marrow donor registry enrollment among healthcare workers: a secondary analysis

Abstract Understanding the factors associated with healthcare workers’ willingness to register as bone marrow donors is essential for developing effective recruitment strategies. The aim of this study was to identify sociodemographic, psychological, and attitudinal factors associated with bone marrow donor registry enrollment among dialysis center healthcare workers in Poland. This secondary analysis included 1,093 healthcare professionals. Multivariable logistic regression was used to identify factors independently associated with bone marrow donor registry enrollment. A total of 208 (19.0%) participants were registered in the bone marrow donor registry. Registry enrollment was independently associated with younger age (OR = 0.96, 95% CI: 0.94–0.98), shorter job seniority (OR = 0.98, 95% CI: 0.95–1.00), history of blood donation (OR = 1.64, 95% CI: 1.38–1.95), support for altruistic living kidney donation (OR = 1.31, 95% CI: 1.06–1.62), willingness to donate one’s own organs after death (OR = 1.67, 95% CI: 1.12–2.49), belief that bone marrow donation is safe for the donor (OR = 1.23, 95% CI: 1.04–1.45), and higher Perspective Taking scores (OR = 1.06, 95% CI: 1.01–1.11). Registry enrollment was associated with younger age and shorter job seniority, prior prosocial behavior, positive attitudes toward donation, and higher cognitive empathy. These findings may help inform future educational strategies aimed at increasing bone marrow donor registry enrollment among healthcare professionals. Given the cross-sectional and secondary nature of the analysis, these findings should be interpreted as associations and do not establish causal relationships.
