The determinants of the willingness to donate an organ among young adults: Evidence from the United States and the European Union

Americans' willingness to give to global immunization programs: Political heterogeneity in preferences for program management and response to priming communications

To develop effective private donation campaigns that support vaccine distribution in low- and middle-income countries (LMICs), one must understand donors' willingness to give, response to stimuli, and preferences for program management. We use a contingent valuation method to estimate United States citizens' willingness to give to nongovernmental COVID-19 immunization programs in LMICs during the emergency phase of the pandemic. Using split-sample treatments, we evaluate the impact of the immunization program administrator (generic NGO or COVAX) and the role of priming communications on inequality in income and vaccination rates between the US and recipient countries. Results show that the median American would donate $42 towards global immunization programs. Preferences for program management and responses to priming communications are heterogeneous across political affiliations, after controlling for altruistic motives, experiences with COVID, giving behaviors, and sociodemographic characteristics. Specifically, Democrats and Independents are more likely to donate to the COVAX-administered fund, and more responsive to priming statements regarding vaccine-gaps. Policy implications are discussed.

Does implementing opt-out solve the organ shortage problem? Evidence from a synthetic control approach

In light of the persistent shortage of organ donations needed to save precious human lives, several countries have modified their organ donation laws by introducing an opt-out system, making every deceased a potential organ donor unless the person has objected. This study examines the impact of adopting opt-out on organ donation rates. Using a panel dataset covering a 21-year period, I apply a synthetic control approach to focus on countries that changed their prevailing organ donation legislation from opt-in to opt-out. I compare them to a synthetic counterfactual from countries that have kept their legislation the same since 1999. Synthetic control estimates show that Argentina and Wales achieved substantially higher organ donation rates with the shift from an opt-in to an opt-out system than without the reform taking place. My findings suggest that as one strategy among others, implementing opt-out cannot solve the organ shortage problem entirely but effectively contributes to reducing it considerably.

The general public's attitude towards accepting payment for kidney donation

Introduction

Kidney transplantation has become the most cost-effective treatment for patients with end-stage kidney disease (ESKD) and offers them the highest quality of life. Yet, kidney donation is often inaccessible due to cultural and traditional beliefs about organ donation. The goal of our study is to assess the value of kidney donation using the Willingness to Accept (WTA) technique. We also aim to understand the factors influencing an individual's willingness to donate an organ.

Methods

A self-administered survey was completed by 985 participants from the general public. The quantitative method and survey design that were chosen used descriptive, correlational, nonparametric, and multivariate statistical tests.

Results

Most of the respondents, 895 (90.9%) are not willing to donate a kidney while alive. Four hundred and five (41.1%) of the respondents are not willing to donate a kidney after their death, while the rest are willing to donate their kidney after their death without financial compensation. The same attitude applies to the donation of a kidney from their relatives. Significant predictors from the results of the logistic regression model in predicting the lowest (minimal) amount that will encourage donation of one kidney after death were: Marital status; Nationality; Adi card holder; Knowing people who need a kidney donation; confidence in the medical staff; and consideration of the family's opinions regarding organ donation.

Discussion

Using cost benefit analysis (CBA), with the aim of evaluating the willingness of individuals to accept payment for innovative medical procedures, such as kidney donation, allows an assessment of the perceived value of the medical procedure and enables policymakers to decide whether to allocate funds or offer subsidies for kidney donation, given the limited healthcare resources available. During our research, we found that most participants did not support the commercialization of organs. Our recommendation for policymakers and health professionals is to continue providing adequate funding for kidney donations and to implement educational programs aimed at improving attitudes towards organ donation.

'Be the Match'. Predictors of Decisions Concerning Registration as a Potential Bone Marrow Donor-A Psycho-Socio-Demographic Study

(1) Background: The study was aimed at a better understanding of the factors determining making a decision to become a potential bone marrow donor, in a Polish research sample; (2) Methods: The data was collected using a self-report questionnaire among persons who voluntarily participated in the study concerning donation, conducted on a sample of the Polish population via Internet. The study included 533 respondents (345 females and 188 males), aged 18-49. Relationships between the decision about registration as potential bone marrow donor and psycho-socio-demographic factors were estimated using the machine learning methods (binary logistic regression and classification & regression tree); (3) Results. The applied methods coherently emphasized the crucial role of personal experiences in making the decision about willingness for potential donation, f.e. familiarity with the potential donor. They also indicated religious issues and negative health state assessment as main decision-making destimulators; (4) Conclusions. The results of the study may contribute to an increase in the effectiveness of recruitment actions by more precise personalization of popularizing-recruitment actions addressed to the potential donors. It was found that selected machine learning methods are interesting set of analyses, increasing the prognostic accuracy and quality of the proposed model.

Kidneys for Sale: Empirical Evidence From Iran

The kidney market in Iran is the only legal market of this sort globally. Yet, it has not been empirically studied based on real data. For the first time, we obtained data on donors and recipients from the Kidney Foundation in Mashhad, April 2011 up to March 2018, and assessed which individualistic characteristics contribute to a kidney’s price. Our findings indicate that each year of education for both donors and recipients increases the kidney price. Moreover, old patients are willing to make a higher payment to young vendors. We have also provided some policy implications to improve the efficiency of kidney allocations.

Sex Disparities in Organ Donation: Finding an Equitable Donor Pool

Background

The majority of living organ donors are women, but few are deceased organ donors, which increases risks associated with sex mismatched organs. We sought to identify reasons for sex disparities in organ donation and strategies for equity.

Methods and Results

Using Amazon's Mechanical Turk, we examined US adults' perceptions regarding donation in a mixed‐methods survey study. Results were compared by sex with Fisher's exact test and T‐tests for quantitative results and qualitative descriptive analyses for write‐in responses. Among 667 participants (55% women), the majority of men (64.8%) and women (63.4%) self‐identified as registered donors. Women's willingness to donate their own organs to family members (P=0.03) or strangers (P=0.03) was significantly higher than men. Donors from both sexes were guided by: desire to help, personal experience, and believing organs would be useless to deceased donors. Non‐donors from both sexes were guided by: no reason, medical mistrust, contemplating donation. When considering whether to donate organs of a deceased family member, women were equally guided by a family member's wishes and believing the family member had no further use for organs. Men had similar themes but valued the family member's wishes more. Among non‐donors, both sexes would consider donation if more information was provided.

Conclusions

In a national survey, both sexes had similar reasons for becoming and not becoming an organ donor. However, compared with men, women were more willing to donate their organs to family members and strangers. Improving education and communicating wishes regarding organ donation with direct relatives may increase sex equity in deceased organ donation.

Usefulness of an organ donation opinion survey as a tool to promote organ donation among the adolescent population

Opinion surveys on health issues are considered health promotion tools. However, no studies have confirmed this in deceased organ donation for transplantation. This study aimed to analyse the impact of completing an opinion questionnaire about deceased organ donation on the attitude towards organ donation among the adolescent population. This longitudinal study with repeated measurements of attitude towards deceased organ donation was conducted with an adolescent population. The measurement instrument was a validated questionnaire of the attitude towards organ donation (PCID-DTO-Ríos). The study process involved the application of the questionnaire at an initial time, 1 month later, and 6 months later. A total of 1374 adolescents participated in this study. The favourable attitude towards donation was 43.1%, which fell to 41.4% at 1 month (P = 0.145), and to 39.7% at 6 months (P = 0.019). Changes in the attitude were observed in all groups, both 1 and 6 months after the questionnaire was completed. There was no objective relationship between the adolescent's socio-family environment and the effect of completing the questionnaire on their attitude towards deceased organ donation. In conclusion, the opinion questionnaire was not useful for promoting organ donation and did not have a positive effect on adolescents' attitudes towards organ donation in the medium or long term.

Are conservatives more charitable than liberals in the U.S.? A meta-analysis of political ideology and charitable giving

Political ideology not only influences political activities, but also apolitical fields such as charitable giving. However, empirical studies regarding political ideology and charitable giving have yielded mixed results. To find out the effect size and explain the variation in effect sizes, we deploy a meta-analysis to estimate the average effect size and examine the potential moderators from four perspectives. Following scientific data collection and coding procedures, we identify 421 effect sizes from 31 empirical studies. Our meta-analysis results suggest that political conservatives are significantly more charitable than liberals at an overall level, but the relationship between political ideology and charitable giving varies under different scenarios. Furthermore, meta-regression results indicate that the measure of charitable giving, the type of charitable giving, and controlling for religiosity can account for the variation in effect sizes.

Determinants of organ donation registration

Rates of organ donor registration range from 20% to 60% throughout the United States. The purpose of this study was to examine sociogeographic differences in organ donor registration rates throughout Missouri to identify varying patterns The organ donor registration rate from each Department of Motor Vehicle office in Missouri was extracted from the National Organ Registration database, office locations were geocoded, and census tract level sociodemographic characteristics were extracted. Spatial regression analyses were conducted to identify relationships between location of DMV offices and census tract-level concentrated disadvantage. Census tract-level concentrated disadvantage (education attainment, poverty, single-headed households) had a significant negative relationship with organ donor registration rates. Yet, census tract-level African American/Black resident concentration was not significantly related to organ donor registration rates. These findings suggest that race-based interventions to recruit organ donors may no longer be necessary. Yet, identifying how characteristics of concentrated disadvantage may be more influential in determining organ donor registration. Gaining a better understanding of how individual decisions are made is integral in the context of increased life expectancy in conjunction with the complex management of chronic conditions.

Restless Feelings: Desiring Direct Contact After Postmortem Organ Donation

This article investigates the emergence of a growing demand in the Netherlands: the wish of organ donor families and organ recipients to establish contact. Such direct contact transgresses both the anonymity and privacy long considered by many to be fundamental to organ donation. Legislation prescribes that privacy should be safeguarded, but the parties involved increasingly manage to find each other. Research is needed to provide insight into the ramifications of direct contact, which may inform mourning counseling and psychosocial support. Drawing on qualitative interviews with donor's relatives, we analyze the reasons for the desire to have direct contact. We seek to understand how meanings are constructed and contested through organs at the margins of life and death in the individualized and secularized society of the Netherlands. We find that relatives struggle with persistent restless feelings after postmortem organ donation and may develop a level of personal attachment and assign inalienability to human body parts.

An Integrated Psychosocial Model of Relatives' Decision About Deceased Organ Donation (IMROD): Joining Pieces of the Puzzle

Organ transplantation remains currently limited because the demand for organs far exceeds the supply. Though organ procurement is a complex process involving social, organizational, and clinical factors, one of the most relevant limitations of organ availability is family refusal to donate organs of a deceased relative. In the past decades, a remarkable corpus of evidence about the factors conditioning relatives' consent has been generated. However, research in the field has been carried out mainly by means of merely empirical approaches, and only partial attempts have been made to integrate the existing empirical evidence within conceptual and theoretically based frameworks. Accordingly, this work articulates the proposal of an Integrated Psychosocial Model of Relatives' Organ Donation (IMROD) which offers a systematic view of the factors and psychosocial processes involved in family decision and their interrelations. Relatives' experience is conceptualized as a decision process about the possibility of vicariously performing an altruistic behavior that takes place under one of the most stressful experiences of one's lifetime and in the context of interaction with different healthcare professionals. Drawing on this, in the proposed model, the influence of the implied factors and their interrelations/interactions are structured and interpreted according to their theoretically based relation with processes like rational/heuristic decision-making, uncertainty, stress, bereavement, emotional reactions, sense of reciprocity, sense of freedom to decide, and attitudes/intentions toward one's own and the deceased's organ donation. Our model also develops a processual perspective and suggests different decisional scenarios that may be reached as a result of the combinations of the considered factors. Each of these scenarios may imply different balances between factors that enhance or hinder donation, such as different levels of uncertainty and potential decisional conflict. Throughout our work, current controversial or inconsistent results are discussed and interpreted on the basis of the relationships that are posited in the proposed model. Finally, we suggest that the structure of the relationships and interactions contained in our model can be used by future research to guide the formulation of hypotheses and the interpretation of results. In this sense, specific guidelines and research questions are also proposed.

Organ Donation Registration and Decision-Making Among Current Blood Donors in the Netherlands

INTRODUCTION

In the Netherlands, there is a constant shortage in donor organs, resulting in long waiting lists. The decision to register as organ donor is associated with several demographic, cultural, and personal factors. Previous research on attitudes and motivations toward blood and organ donations provided similar results.

RESEARCH QUESTION

The current study investigated demographic, cultural, and personal determinants of organ donation registration among current Dutch blood donors.

DESIGN

We used data from Donor InSight (2012; N = 20 063), a cohort study among Dutch blood donors, to test whether age, gender, religious and political preferences, donor attitude, and altruism predicted organ donor registration among current blood donors.

RESULTS

Organ donors were more often represented in the blood donor population compared to the general Dutch population. Women showed a higher propensity to be registered as organ donor. Higher education as well as higher prosocial value orientation, prosocial behavior, that is, doing volunteer work, and awareness of need significantly associated with being registered as organ donor. Religious denomination negatively predicted organ donation registration across all faiths.

DISCUSSION

Results are discussed in light of cultural context, and possible implications for improving information provision and recruitment are mentioned.

Knowledge and attitudes toward corneal donation among Singaporean youth: a cross-sectional study

Background

To assess the knowledge of Singaporean youth regarding corneal donation and gauge their willingness to donate their corneas.

Methods

We conducted a cross-sectional study among 500 students from five tertiary institutions in Singapore. All students answered self-administered questionnaires which included seven questions that tested knowledge and three questions that determined willingness to donate corneas.

Results

Among 500 Singaporean youth aged 18 to 25, most students (73.2 %) answered 3 or fewer of the 7 questions about corneal donation correctly. With regards to the willingness to donate, 155 (31 %) were willing to donate their corneas, 111 (22.2 %) were not willing to donate their corneas, and 234 (46.8 %) were undecided. Willingness to donate corneas was associated with an older age group (21 to 25 years old), those who are non-Muslims, and have good basic knowledge. Particularly, students with good basic knowledge were 1.71 times more likely to willingly donate their corneas.

Conclusion

The knowledge of the Singaporean youth regarding corneal donation and transplantation is poor. Since insufficient information was cited as the most common reason for being undecided in regards to corneal donation, specific and tailored programs to increase knowledge and awareness are needed to convince the youth to support corneal donation.

Socioeconomic status and ethnicity of deceased donor kidney recipients compared to their donors

Public perception and misperceptions of socioeconomic disparities affect the willingness to donate organs. To improve our understanding of the flow of deceased donor kidneys, we analyzed socioeconomic status (SES) and racial/ethnic gradients between donors and recipients. In a retrospective cohort study, traditional demographic and socioeconomic factors, as well as an SES index, were compared in 56,697 deceased kidney donor and recipient pairs transplanted between 2007 and 2012. Kidneys were more likely to be transplanted in recipients of the same racial/ethnic group as the donor (p < 0.001). Kidneys tended to go to recipients of lower SES index (50.5% of the time, p < 0.001), a relationship that remained after adjusting for other available markers of donor organ quality and SES (p < 0.001). Deceased donor kidneys do not appear to be transplanted from donors of lower SES to recipients of higher SES; this information may be useful in counseling potential donors and their families regarding the distribution of their organ gifts.

The role of disparities and socioeconomic factors in access to kidney transplantation and its outcome

BACKGROUND

Research focused on identifying vulnerable populations and revealing specific risk factors for barriers along the pathway from ESRD to kidney transplantation has been mostly descriptive and the causes of existing disparities remain unclear. However, several socio-economic factors that are associated with the access to and the outcome of the kidney transplantation have been identified.

SUMMARY

While the presence of racial, gender, and geographic disparities is noted, we were interested mostly to describe potential socio-economic factors associated with and possibly responsible for the presence of such disparities. In this review we focused on five factors: education level, employment status, income, presence of substance addiction or abuse, and marital status. We describe the new method to quantify patients' socio-economic status and identify the group of high risk in terms of the transplant outcome, easily calculated social adaptability index, previously associated with clinical outcome in several patient populations including those with kidney transplant. At the end, based on literature analyzed we offer potential interventions that potentially can be used in order to reduce the degree of disparities.

CONCLUSION

Based on review of literature socio-economic factors are associated with and possibly responsible for healthcare disparities. Social adaptability index allows quantifying the degree of socio-economic status and identifying the group of high risk for inferior transplant outcome.

A student leadership model for promoting educational programs in organ donation and transplantation

The global organ shortage is the strongest factor for the increase in transplant wait time and deaths on waitlists. Here we describe a model for involving high school students in education research around organ donation and transplantation and capitalize on the strength of a pre-existing educational program offered by the local organ procurement organization (OPO). While training in education research at Cleveland Clinic, a high school student embarked on a collaborative project with the local OPO. The project involved evaluating three educational programs, selecting the most appropriate program for administration at her school, coordinating with the student's school administration and teachers, administering an assessment tool for the effectiveness of the program, and analyzing the results. The local OPO program that was selected for implementation consisted of a video presentation entitled "Share your life, share your decision" prepared by the United States Health Resources and Services Administration (HRSA), lectures by invited speakers and an educational assessment (pre- and post-education). The assessment survey included 3 multiple choice and 7 true/false questions. Compared to the over 2500 programs administered in the last 5 years by the local OPO, this program had a higher volume of participation (n = 353 compared to an average of 150 students/day). Students correctly classified transplantation status of more organ and tissues post-education (P < .0001 for both). For 5 out of the 7 true/false questions, students correctly answered questions more frequently post-education (P ≤ .002 for all). This experience included for the first time a formal assessment of the program which will be utilized to address targeted areas for specific improvements. This student collaborative model of involving students in organ donation and transplantation related education research has the potential to promote and maximize the effectiveness of educational programs targeting their peers.

First global forum on education on organ donation and transplantation for schools

The Transplantation Society, in collaboration with the Canadian Society of Transplantation, organized a forum on education on ODT for schools. The forum included participants from around the world, school boards, and representatives from different religions. Participants presented on their countries' experience in the area of education on ODT. Working groups discussed about technologies for education, principles for sharing of resources globally, and relationships between education, and health authorities and non-governmental organizations. The forum concluded with a discussion about how to best help existing programs and those wishing to start educational programs on ODT.

The organ donation conundrum

A discrepancy exists between the demand for and the availability of solid organs for transplant. Barriers to organ donation can be encountered at 2 key points: (1) when trying to increase the number of people willing to become organ donors and registering their intent and (2) at the time of organ procurement. Several predictors of individual willingness to register as an organ donor are discussed, along with issues surrounding families' refusal of consent or failures in the hospital system to identify potential donors. Several countries have adopted presumed-consent policies and have seen a subsequent increase in donation rates. Research is needed to explore the effectiveness of approaches to overcome the barriers to individual registration and family consent, particularly in countries where presumed consent has not been and is not likely to be adopted.

Tissue banking: relationship with blood donor and organ donor card status

Understanding the relationships among altruistic health acts may serve to aid therapeutic research advances. In this paper, we report on the links between two such behaviours—donating blood and carrying an organ donor card—and willingness to donate urological tissue to a tissue bank. Reasons for the differential willingness to do so are examined in this paper. A systematic sample of 259 new and returning attendees at a tertiary urology referral clinic in Ireland completed a self-report questionnaire in an outpatient setting. In addition to demographic details, details of known diagnosis of malignancy and family history of cancer; attitudes to tissue donation for research purposes were gauged using a 5-point Likert scale. Both blood donors and organ donor card carriers were more likely to be willing to donate tissue for research purposes. Blood donors were more likely want to know their overall results in comparison to nonblood donors and want their samples to be used for nonprofit research. Our hypothesis that being a blood donor would be a better predictor to donate urological tissue than being an organ donor card carrier borne out by the trends reported above.

Factors Influencing Living Kidney Donation in Singapore

Context—

Kidney transplantation is the best treatment option for kidney failure, but the supply of donor kidneys remains small.

Objective—

To understand the public's attitude toward living donor kidney donation in Singapore.

Design, Setting and Participants, Intervention, Outcome Measures—

A cross-sectional study of a convenience sample of 1520 members of the general public seeking care at local medical centers. A self-administered questionnaire included questions on demographics and subjects' willingness and unwillingness to donate a kidney. Respondents were aged at least 18 years and did not have underlying chronic kidney disease, end-stage renal disease requiring dialysis, or history of kidney transplant.

Results—

Overall mean age of respondents was 49 (SD, 15) years and 50% were male. Response rate to the question on “willingness to donate kidney while alive” was 96% (1460); 707 (48.4%) were willing to donate a kidney while alive. Respondents who were willing to donate were younger (<40 years; P < .001); had above a secondary level education ( P < .001); had monthly household income 2000 SGD (or US$1660; exchange rate at 1 SGD = US$0.83) or higher ( P< .001); were not married, single, or divorced ( P< .001); and were professionals ( P< .001). Fear of surgical risks (86.5% strongly agree or agree) and poorer health consequent to donation (87.5% strongly agree or agree) were the main reasons for not considering being a living kidney donor. Demographic factors and concerns of surgical risks and ill health after transplant influenced willingness to donate a kidney while alive. Addressing these concerns may alleviate anxiety with regard to living kidney donation.

Knowledge and attitudes of Polish university students toward organ donation and transplantation

Although the number of patients needing organ transplantation systematically increases, recent years have seen a considerable shortage of donors. The level of knowledge and attitudes toward donation are critical factors in achieving the required balance between supply and demand. This pilot study assessed the knowledge, opinions, and behaviors related to organ donation and transplantation among 625 students representing eight different fields of study from the University of Rzeszow in south-eastern Poland. Although the participants provided evidence of knowledge about human organ donation and transplantation, they were aware of the main organs of the human body for potential transplants, and generally showed positive attitudes; only 24% of the subjects indicated their willingness to register as a donor; only 3% stated that they had already registered and had a donor card. The findings suggest that good intentions do not translate into action and that Poland needs to develop a nation-wide, up-to-date, and youth-oriented health education program that builds on favorable attitudes toward organ donation and transplantation.

Donating organs: a theory-driven inventory of motives

Two studies examined the motives that lay behind patients' acceptance or reluctance at donating organs after death. They also examined the way these motives were related to demographic characteristics, personality, and signing a donor card. Six separable motives for donation were found: Financial Incentive, Humanistic or Religious Duty, Positive Consideration from Others, Living on Through a Receiver, Gift of Life, and Close Others. Five motives for not donating were found: Preserving the Absolute Integrity of the Corpus, Strict Individualism, Lack of Control over the Use of the Organs, Anonymity of the Procedure, and Respecting Family Wishes. These motives were linked to personality factors in a meaningful way. Willingness to sign was higher among female participants and among participants with lower scores on Integrity of the Corpus and higher scores on Duty and Gift of Life. When Integrity of the Corpus scored highly, however, the effect of the other factors was practically eliminated. In other words, Integrity of the Corpus acted as a protected value: Trying to change people's belief that the integrity of the corpus at death is a sacrosanct issue would come with its own ethical issues.

Increasing liver transplantation waiting list mortality: a report from the Australian National Liver Transplantation Unit, Sydney

BACKGROUND

We aimed to describe the demand for liver transplantation (LTx) and patient outcomes on the waiting list at the Australian National Liver Transplantation Unit, Sydney over the last 20 years.

METHODS

We performed a retrospective analysis with the data divided into three eras: 1985-1993, 1994-2000 and 2001-2008.

RESULTS

The number of patients accepted for LTx increased from 320 to 372 and 548 (P < 0.001) with the number of LTx being performed increasing from 262 to 312 and 452 respectively (P < 0.001). The median adult recipient age increased from 45 to 48 and 52 years (P < 0.001) while it decreased in children from 4 to 2 and 1 years respectively (P = 0.001). In parallel, the deceased donor offers decreased from 1003 to 720 and 717 (P < 0.001). Methods to improve access to donor livers have been used with the use of split livers, extended criteria and non-heart beating donors, resulting in increased acceptance of deceased donor offers by 65% and 115% in the second and third eras when compared with the first era (P < 0.001). However, the adult median waiting time has increased from 23 to 41 and 120 days respectively (P < 0.001). This was associated with increased adult mortality on the waiting list from 23 to 40 and 122 respectively (P < 0.001).

CONCLUSIONS

Despite the increasing proportion of donor offers being used, the waiting list mortality is increasing. A solution to this problem is an increase in organ donation to keep pace with the escalating demand for LTx.

Attitudes and opinions on organ donation: an opportunity to educate in a Canadian city

BACKGROUND

Patients on organ transplant waiting lists continue to far exceed donor rates. We seek to understand the barriers preventing people in a Canadian city from donating organs for transplantation.

METHODS

One thousand adults were surveyed assessing knowledge, personal involvement, and attitudes about organ donation in an urban center in Canada. Primary outcomes of interest were a signed organ donor card and willingness to donate.

RESULTS

Of those surveyed, 64% did not realize that they possessed an organ donor card; 90% would consider being a donor if a friend was in need of an organ. Of the 36% who did know, 72% had signed it. Those who had misconceptions about the organ donation process were less likely to be donors.

INTERPRETATION

There is a tremendous lack of knowledge about organ donation. While the majority of people are interested in organ donation, they lack a means to express this interest - most do not even realize they possess an organ donor card. A significant proportion of people who were not supportive of donation were misinformed in critical areas of knowledge that likely influenced this decision including the rich being preferentially transplanted, the consent process, disfigurement, and donors receiving worse medical care.

Beyond the 'embryo question': human embryonic stem cell ethics in the context of biomaterial donation in the UK

Discussion about the ethics of human embryonic stem cell (ESC) research in the UK tends to be dominated by the divisive and potentially intractable issue of the moral status of the embryo. This can have the effect of silencing or marginalizing other concerns, especially in the context of public engagement with science in this field. One such area of potential public concern is the donation of oocytes and embryos to stem cell research. Contemporary research on the views of donors and potential donors about a wide range of biomaterials, from solid organs to gametes and bone marrow, is reviewed and used to illustrate the range and types of ethical concerns articulated by this important group of stakeholders. Attitudes to donation are found to vary according to the type of tissue being donated or collected, the purpose for which donation is being sought and the nature of the recipient of the donation. Pertinently, attitudes towards donating oocytes are found to differ in some respects from donation of embryos or fetal tissue. The implications of these findings for ensuring ethically robust informed consent and publicly acceptable sourcing of human biomaterials for stem cell research are then considered.

Enforcement of presumed-consent policy and willingness to donate organs as identified in the European Union Survey: the role of legislation in reinforcing ideology in pluralistic societies

To increase the supply of transplantable organs, some European Union (EU) countries have begun implementing and enforcing presumed consent policies for organ donation. Mossialos and colleagues performed an analysis of samples of citizens in 15 EU countries and found that legislation, enforcement, and awareness of presumed consent policies for organ donation increase people's willingness to donate their own organs and those of a deceased relative. The authors concluded that, in countries with enforced presumed consent, citizens are willing to donate because they accept organ donation as an ideology. This ideology originates in the thinking that organ donation is an implicit communal contract i.e., a mechanism by which individuals pay back society for the inclusion and social support that they have already experienced and hope to experience in the future. Acceptance of this ideology enhances people's willingness to donate organs and the efficiency in pursuing this collective action, thus, paving the way toward increased paternalism in society. We highlight some potential biases that may have been incorporated in the survey design and in Mossialos et al.'s conclusions, including (1) how the survey questions were constructed, (2) whether sufficient information was communicated about organ procurement practices in heart-beating and non-heart-beating donation before participants responded to the survey, and (3) whether respondents' knowledge about donation legislation can be equated with understanding of processes involved in organ donation. We address the consequences of using legislative authority to enforce the ideology of organ donation, thereby superseding the varying moral values, beliefs, and attitudes about human life and culture that are inherent in multicultural societies.
