Abstract 16: Sex Disparities in Organ Donation: Finding an Equal Donor Pool

Introduction: The majority of living organ donors are women, and the majority of deceased organ donors are men. This poses a problem for transplant candidates who have worsened survival with sex mismatched organs. The objective of this study was to identify reasons for disparities in organ donation between sexes and identify strategies to increase organ donors. Methods: We conducted a fifteen question survey using a crowdsourcing marketplace, Amazon’s Mechanical Turk, in September 2019. The survey assessed how participants make decisions about becoming an organ donor. The survey was distributed to U.S. adult participants, including eight write-in questions and two Likert scale questions. Qualitative descriptive analyses were used to understand reasons for and against becoming an organ donor. Quantitative results were compared with t test. Results: Among the 667 eligible participants representing 49 states, 54.9% were women and 63.1% were in the 18-40 age group. The majority of men (64.8%) and women (63.4%) were registered organ donors. Among men and women donors, three themes guided their willingness to donate: desire to help others, personal experience with organ donors/recipients, and believing organs would have no use to the donor once dead. Among men and women non-donors, decisions were guided by three themes: no reason, medical mistrust, considering becoming a donor. Themes varied by sex when considering whether to donate organs of a deceased family member. Women were guided equally by two themes: family member’s wishes and believing the deceased family member had no further use for organs. Men had similar themes but valued the family member’s wishes more. Women’s willingness to donate their own organs to family members (p=0.03) and strangers (p=0.02) was significantly higher than men. Among non-donors, both sexes would consider becoming organ donors if more information was provided. Conclusion: In a national survey of adults, women and men had similar reasons for becoming and not becoming an organ donor. However compared to men, women were more willing to donate their organs and more altruistic in the donation of family members’ organs. Women’s deceased organ donation may increase with further communication of women’s wishes before death and by improved public education about organ donation.
