Factors Associated with Intention to Donate Hematopoietic Stem Cells among Blood Donors

An undergraduate service-learning project to teach immunology concepts while increasing healthcare equity by enhancing access to stem cell donors among underrepresented populations

Active learning has been shown to increase STEM student engagement and decrease the achievement gap among underrepresented students. As a parallel to the lack of equity in STEM education, BIPOC patients who require a life-saving hematopoietic cell transplantation (HCT) are much less likely-sometimes less than half as likely-than individuals of White-European descent to find a suitable donor when using the National Marrow Donation Program (NMDP). The Be the Match (BtM) Registry has made significant improvements in the likelihood of matching underrepresented patients, but the disparity persists. This activity uses a service-learning project to teach undergraduate students about stem cell donation and to add potential stem cell donors to the BtM Registry. A small data set of pre-/post-surveys from one cohort shows learning gains on the topic of HCT. The approach is flexible and scalable, and students overwhelmingly reported the project as a great use of class time and very rewarding.

Assessing the cognition, attitudes and intentions of volunteers regarding unrelated peripheral blood stem cell donation: The UPBSC-DQ instrument in Chinese

Objectives

This study aimed to develop and validate the Unrelated Peripheral Blood Stem Cell Donation Questionnaire (UPBSC-DQ) (an instrument in Chinese) to assess the degree of cognition, attitude and intention of enrolled volunteers towards UPBSC donation.

Methods

The development process of the UPBSC-DQ was performed in a stepwise approach that included extensive literature retrieval, expert revision, and pretesting with 442 students. We conducted an online cross-sectional survey using the final version of the UPBSC-DQ among 336 participants. The reliability of the questionnaire was assessed by Cronbach's α and corrected item-total correlation (CITC), and the validity was evaluated by a correlation coefficient matrix, confirmatory factor analysis (CFA), and t-test.

Results

The UPBSC-DQ consists of four domains: basic information, cognitive, attitude, and intention. The Cronbach's α values were 0.88 and 0.86 for the attitude and intention scales, respectively, indicating strong internal consistency and good reliability. Correlation analysis and CFA showed good structure and content validity. Interitem correlations indicated that each item had only a weak correlation with the other scales.

Conclusions

The UPBSC-DQ is a reliable and valid assessment questionnaire for individuals' attitudes and intentions towards UPBSC donation. The questionnaire showed good to high reliability, content and construct validity.

Factors Influencing Individuals' Decision-Making Regarding Hematopoietic Stem Cell Donation: A Cross-Sectional Study in Saudi Arabia

INTRODUCTION

Hematopoietic stem cell transplantation (HSCT) is a vital medical intervention for treating various conditions. The preferred methods, i.e., bone marrow transplantation and peripheral blood stem cell transplantation, have saved lives and attracted attention. Saudi Arabia, with a high sickle cell disease and leukemia incidence, faces the challenge of matching donors for HSCT. Factors like knowledge, attitudes, cultural beliefs, and access to information impact donation decisions.

METHODS

In May 2023, a cross-sectional online survey was conducted in Saudi Arabia, targeting the general population. Data were collected through an online questionnaire, analyzing demographics, knowledge, attitudes, and factors influencing donation intention.

RESULTS

Demographic analysis showed that females, younger individuals (18-25 years), those with higher education, and healthcare workers had better knowledge. Attitudes toward donation varied: 42.4% were willing to donate, while 57.6% were not. Psychological barriers, health concerns, pain, and inadequate knowledge influenced donation reluctance. Of the participants, 3.5% were registered stem cell donors, with 58.8% expressing willingness but not registered. Donors' intent was influenced by family members' need for transplants and knowledge. A majority (56.6%) supported employer support for health programs, while 65.7% believed government funding should assist donors.

CONCLUSION

HSCT is vital in treating diseases like sickle cell and leukemia in Saudi Arabia. While many recognize its importance, knowledge gaps about its specifics and donation deter potential donors. Enhanced awareness campaigns and support from employers and the government could increase donor registrations.

Knowledge about stem cell sources and obstacles in donation of bone marrow and peripheral blood stem cells: a cross-sectional survey from Ha'il city to track the prospects of regenerative medicine in Saudi Arabia

BACKGROUND

Promoting stem cell donation behaviors could be crucial in advancing stem cell-based treatment, research and improving public health in Saudi Arabia. Donation of stem cells can be considered an act of social welfare just like blood donation because stem-cell-based therapies are emerging as a hope for those suffering from chronic health conditions and/or terminal illnesses.

AIM

This study aims at assessing levels of awareness about sources of stem-cells, donor organizations and predictors of stem cell donation behavior in target population.

METHODS

The study employed a cross-sectional online survey method. The study sample comprises 1325 educated Saudi people living in Ha'il city. The survey questionnaire collected data about respondents' demographic background, awareness about various sources of stem cells and stem-cell donor registries, willingness to donate stem cells, registration status and obstacles in stem cell donation registration. Percentages, Chi-square analysis and Odd Ratios were computed to analyze the data.

RESULTS

In this sample, (n = 696; 52%) were males and (n = 629; 48%) were females. Although (n = 1308; 98%) percent of respondents reported willingness to donate stem cell, less than one percent (n = 6; 0.5) were registered with Saudi Stem Cell Registry. Over 50% of respondents hold inaccurate perceptions about sources of stem cell. Odd Ratio (OR) values from binary logistic regression model identified four factors as significant predictors of non-registration status. These included (i) unaware about donor agencies and procedures (OR = 10.07; p < 0.05), (ii) unaware about possibility to donate stem cells (OR = 8.08; p < 0.05) (iii) concerns about impact on health (OR = 10.01; p < 0.05) and (iv) have health issues that does not permit donation (OR = 10.50; p < 0.05).

CONCLUSION

Stem cell registrations can be enhanced through appropriate health education programs that focus on increasing awareness about donation procedures, trustworthy donor organizations and reducing people apprehensions related to donation.

A review of whole-blood donors' willingness, motives, barriers and interventions related to donating another substance of human origin

Diversification of blood collection agencies' (BCAs) core business requires donors to donate substances of human origin (SoHO) beyond whole-blood. Whole-blood donors are assumed to be willing to convert to donate other SoHO as well as whole-blood. However, no reviews consider the evidence on conversion (i.e., willingness/intention, behaviour, retention, attrition). This rapid review provides a narrative synthesis of whole-blood donors' conversion to another SoHO, characteristics contributing to conversion, motives and deterrents, and interventions encouraging conversion. Sixty-five studies were reviewed. Most were cross-sectional and examined whole-blood donor conversion to organ (willingness/pledge for deceased donation), plasma or stem cell donation. Most examined conversion rather than characteristics contributing to conversion, motives, deterrents or interventions. Whole-blood donors appear willing to donate another SoHO, yet conversion rates are unclear. Besides self-efficacy, there is little consistency in reported characteristics of donors converting, and few theories applied to understand characteristics encouraging conversion. Intrinsic (altruism, self-esteem, curiosity) and extrinsic (perceived need, service experience, direct requests) motives and barriers (lifestyle, fearing reduced health) appear important and require further research. Interventions encouraging conversion need replication and may include in-person, in-centre approaches, raising awareness of the functional benefits of other SoHO (high need, usefulness), and developing promotional materials that pique donors' curiosity, invite questions, and encourage donor-initiated conversations about conversion. Centralising BCAs as a single business or partnering with other organisations appears mutually beneficial to encourage conversion and sustainable panels/resources. Research is needed to understand the impact of encouraging conversion on donors and organisations, and identify optimal management strategies for multi-SoHO donors.
