Letter to the Editor: Bridging knowledge gaps in organ donation - implications for transplantation and regenerative therapies

Abstract

The ongoing global deficit of donor organs remains a significant obstacle for transplantation programs, with more than 100000 individuals currently listed for transplantation in the United States and an estimated 13 patients dying each day before receiving a suitable organ. This commentary integrates current evidence regarding public knowledge, perceptions, and barriers to organ donation, and connects these factors to the anticipated acceptance of emerging transplantation and regenerative medicine innovations. Despite widespread support for organ donation-reported among nearly 90% of United States adults-actual enrollment in donor registries remains disproportionately low, underscoring a persistent disconnect between positive attitudes and real-world participation. Recent findings from the United Arab Emirates, including the study by Al-Sharbatti et al, reveal notable gaps in understanding and fear of medical procedures as key deterrents to donor enrollment, trends similarly reported in regions such as Kazakhstan. These insights reaffirm that inadequate awareness and distrust of healthcare systems continue to impede donor registration, even in highly educated communities. Enhancing public education, promoting transparency, and fostering trust are crucial steps toward improving donation rates. As transplantation advances through innovations such as xenotransplantation, stem cell–derived tissues, and bioengineered organs, societal confidence will be pivotal in shaping their acceptance. Addressing current knowledge deficits and proactively engaging with ethical and societal considerations will be essential to fully realizing the potential of both conventional and next-generation transplantation therapies.

Core Tip: Global organ shortages remain a pressing challenge, with societal perceptions shaping willingness to donate. Findings from Al-Sharbatti et al show that even among academic communities, myths, insufficient knowledge, and distrust continue to limit donor registration. Addressing these barriers requires culturally sensitive education, open communication, and active collaboration with communities to strengthen confidence in the system. These insights are equally relevant to future frontiers, including xenotransplantation and stem cell-derived organs, where public trust will determine acceptance. Building awareness, dispelling fears, and promoting ethical engagement are therefore essential to ensure that both current transplantation practices and innovative regenerative approaches achieve their full potential in saving lives.

TO THE EDITOR

The shortage of donor organs remains a pressing global challenge. In the United States alone, more than 100000 individuals are currently on transplant waiting lists, with an estimated 13 patients dying each day before receiving a suitable organ[1-3]. This imbalance between need and availability reflects a worldwide crisis in transplantation[4]. This manuscript is a narrative commentary that integrates current evidence and expert perspectives on public awareness and confidence in organ donation, emphasizing their relevance for the development and acceptance of emerging transplantation approaches. Public perceptions and attitudes exert significant influence on donation rates; although surveys indicate that around 90% of United States adults express support for organ donation, only about 60% are formally registered. This persistent “attitude–behavior gap” is often linked to misconceptions and uncertainty surrounding the process. The recent study of World Journal of Transplantation by Al-Sharbatti et al[5] in the United Arab Emirates illustrates this phenomenon: Despite widespread acknowledgment of the importance of donation, most university participants had never engaged in the practice. The main barriers identified were limited awareness (approximately 64%) and apprehension about medical interventions (around 52%). Such observations are consistent with global trends, where inadequate knowledge and mistrust continue to restrict donor registration and participation[5-7].

In the United Arab Emirates, Al-Sharbatti et al[5] conducted a survey of 607 students, faculty, and staff across Ajman campuses, revealing generally favorable attitudes toward organ donation. Support was particularly pronounced among individuals with prior personal or family experience, higher levels of knowledge, or affiliation with specific institutions. A notable finding was the strong association between knowledge and willingness to donate, with attitudes becoming significantly more positive in participants who demonstrated greater awareness of organ donation (P < 0.001). According to AlSharbatti et al[5], in a survey of 607 university participants, higher knowledge levels were significantly associated with greater willingness to donate (P < 0.001). These results emphasize that increased awareness and previous personal or familial experience with organ donation are correlated with a stronger inclination to participate as donors. Conversely, persistent barriers-including fear and misinformation-remained influential deterrents. Comparable observations were reported in a Kazakhstani survey, where inadequate knowledge and widespread mistrust of the healthcare system were identified as leading obstacles to donation. Collectively, these studies underscore that even within well-educated populations such as university communities, critical knowledge gaps and uncertainties continue to hinder the translation of supportive attitudes into actual donor participation[5,7,8]. Although both populations demonstrated gaps in knowledge, concerns about the healthcare system were particularly pronounced among participants from Kazakhstan, highlighting contextual variations in institutional trust.

OVERCOMING BARRIERS: THE ROLE OF EDUCATION AND TRUST

Bridging the gaps in organ donation requires a dual focus on education and trust-building through transparent communication. Deficiencies in knowledge can be mitigated by culturally tailored awareness initiatives and incorporation of structured content into educational curricula. For instance, university-based workshops and courses dedicated to organ donation have been shown to improve familiarity, dispel myths, and foster positive attitudes. In the United Arab Emirates, the “Hayat” national program exemplifies this approach by prioritizing community engagement to strengthen public trust. Evidence consistently demonstrates that improved understanding is directly associated with greater willingness to donate[5].

Equally important is addressing mistrust, a significant barrier to donor registration. Concerns that medical professionals may not act in the best interests of potential donors, or that organs could be misallocated, have been shown to suppress donation rates. Historical evidence from several countries reveals that public scandals can sharply erode participation, whereas transparency, rigorous oversight, and widely shared accounts of successful transplant outcomes can restore confidence. In practice, fostering collaboration with trusted community stakeholders-such as religious authorities, educators, and local leaders-can help normalize donation and reassure the public. Clear communication should also address common fears, including the safety of retrieval procedures, while emphasizing the altruistic impact of donation[9].

Key strategies to strengthen both knowledge and trust include

Targeted education: Develop tailored programs for students, healthcare trainees, and young adults to cultivate factual understanding and empathy toward donors.

Community engagement: Involve patient advocacy groups, opinion leaders, and media platforms to correct misconceptions and promote donation as a shared societal value.

Transparency and oversight: Publicize ethical safeguards such as consent frameworks and equitable allocation policies to reinforce confidence in the system.

Positive narratives: Highlight personal stories of donors and recipients, supported by survival outcomes, to humanize the process and inspire public commitment.

These strategies can foster a cultural environment more conducive to organ donation[7,9]. Extending these educational and community-based approaches, the subsequent challenge is to apply insights from traditional organ donation frameworks to the advancing fields of regenerative medicine and transplantation research.

FUTURE DIRECTIONS: REGENERATIVE MEDICINE AND PUBLIC ENGAGEMENT

As transplantation continues to evolve, societal acceptance will remain pivotal-whether the organs are sourced from human donors or generated through laboratory technologies. The insights from Al-Sharbatti et al[5] extend naturally to the field of regenerative medicine. Innovative strategies such as xenotransplantation (use of animal organs) and stem cell–derived tissues hold promise for alleviating donor shortages, yet they face comparable social and ethical challenges. For example, a recent survey in the United States reported that only about 36% of respondents were willing to accept a porcine organ even under medical necessity, while 57% voiced concerns about unforeseen complications. These findings highlight the authors’ conclusion that expanding public acceptance is essential for the progress of these technologies. Similarly, the successful integration of stem cell-based organs or organoids will depend on fostering trust in both their safety and the ethical standards governing their development. Public discourse surrounding stem cell therapies-addressing issues of cell origin, regulatory oversight, and realistic expectations-should advance in parallel with discussions on organ donation[10].

Ultimately, trust and knowledge serve as the foundation across all transplantation modalities. Without them, even the most sophisticated innovations-be they bioengineered tissues, xenografts, or artificial organs-risk encountering the same barriers that hinder traditional donation programs when public confidence declines. Building this trust requires proactive engagement: Educating communities about the potential and limitations of emerging therapies, ensuring transparency in consent processes, and providing platforms for dialogue. Initiatives such as public forums or ethical surveys on regenerative medicine can help surface and resolve concerns before these therapies reach clinical application[9,10].

Nonetheless, ethical considerations in regenerative therapies-including stem cell sourcing, xenotransplantation, and fairness in access-continue to play a pivotal role in shaping public acceptance.

CONCLUSION

A unique aspect of this commentary is its conceptual integration of public confidence in existing organ donation frameworks with the prospective acceptance of regenerative and xenotransplantation technologies. The findings of Al-Sharbatti et al[5] highlight that advancements in science need to be accompanied by societal preparedness, as well-informed and actively engaged communities tend to exhibit lower hesitancy toward organ donation. In the face of persistent global organ shortages, only through these combined efforts-bridging present challenges with tomorrow’s innovations-can transplantation achieve its full life-saving potential worldwide. These insights can be translated into practice by policymakers and educators through the integration of organ donation education into health curricula and the implementation of outreach initiatives that emphasize ethical transparency and the broader societal value of donation.
