Conclusion: This study aimed to establish whether factors such as anticipated regret, the deceased wishes and next-of-kin attitudes could predict next-of-kin approval for organ donation, and to develop a model of next-of-kin decision making regarding organ donation in Wales, UK, which has an opt-out system. A total of 808 participants were randomly assigned to imagine whether a deceased relative had either opted-in, opted-out or had not registered a decision (deemed consent). The authors concluded that anticipated regret significantly influenced the next-of-kin approval for organ donation, and also that if the next-of kin had negative beliefs towards organ donation, they were less likely to follow the deceased wishes to donate. It is possible that the participants may have underestimated the influence of their emotions on future decision-making process; thus, how they believed they would act may be different from how they behave in real life. The authors do a good job of acknowledging this. However, the study did not assess ethnicity or religion, both of which have been found to affect the decision of the next-of-kin on organ donation. These could have acted as potential confounders in the analyses. Perhaps another factor the authors could have also considered is the type of relationship between the deceased donor and the next-of-kin. It would have been interesting to see if relatives with negative attitude towards organ donation were able to override their beliefs and follow the deceased donor’s wishes to donate if the deceased donor was an authority figure or a final decision maker when alive. For example, in cultures where fathers are the main decision makers, there may be a higher chance of sons/daughters respecting their deceased father’s wishes to donate despite their negative affective attitudes, in comparison to fathers respecting their deceased children’s wishes.
Aims: This study aimed to investigate how the deceased donor’s wishes, negative affective attitudes, perceived benefits and anticipated regret had an effect on the next-of-kin’s approval of organ donation under opt-out legislation.
Interventions: Participants were randomised to imagine if their deceased relative had either opted in, opted-out or not registered a decision (deemed consent).
Participants: Adults (≥18 years) living in Wales.
Outcomes: The outcome variables of interest included previous health-based philanthropy, uncertainty, anticipated regret, intention of next-of-kin to approve donation of organs, negative affective attitudes and perceived benefits.
Follow Up: Not reported
RATIONALE:

Family, and sometimes longstanding friends, have considerable influence over organ donation, through agreeing or disagreeing to the donation of a deceased individual's organs. To date, most research has been undertaken within opt-in systems.

OBJECTIVE:

This study advances on previous research by assessing next-of-kin approval under opt-out legislation. We tested whether next-of-kin approval varies when the deceased is a registered donor (opted-in), registered non-donor (opted-out) or has not registered a decision under an opt-out policy (deemed consent). We also tested if the deceased's wishes influenced next-of-kin approval through relatives anticipating regret for not donating and feelings of uncertainty. Finally, we assessed whether next-of-kin's own beliefs about organ donation influenced whether they followed the deceased's wishes.

METHODS:

Participants (N = 848) living in a country with opt-out legislation (Wales, UK) were asked to imagine a relative had died under an opt-out system and decided if their relatives' organs should be donated. Participants were randomly allocated to imagine the deceased had either (i) opted-in, (ii) opted-out or (iii) not registered a decision (deemed consent). The outcome variable was next-of-kin approval, with uncertainty and anticipated regret as potential mediators and next-of-kin's beliefs about organ donation as moderators.

RESULTS:

Next-of-kin approval was lower when the deceased had opted-out than under deemed consent. This was due to next-of-kin anticipating more regret for not donating under deemed consent than opt-out. Further analyses revealed the deceased's wishes influence next-of-kin approval, via anticipated regret, when next-of-kin did not hold negative beliefs about organ donation.

CONCLUSIONS:

The deceased's wishes were less likely to be followed when next-of-kin had negative beliefs towards donation. Developing large-scale campaigns to improve these beliefs in the general public should make people more likely to follow the deceased's wishes. As a result, these campaigns should improve the availability of donor organs.

OBJECTIVES:

To understand the barriers towards deceased organ donation among Indians living globally.

DESIGN:

Integrative systematic review using narrative synthesis.

DATA SOURCES:

CINAHL, Medline full-text, PsycInfo, Scopus, Global Health, Web of Science, and PubMed Central, Indian Journal of Transplantation and Google Scholar.

TIME PERIOD:

1 January 1994 to 31 December 2021.

PARTICIPANTS:

Individuals of Indian origin living globally.

RESULTS:

Eighty-nine studies were included with more than 29 000 participants and quality of the studies were assessed using Joanna Briggs Institute's critical appraisal tool. Though majority of the participants had knowledge toward organ donation with a positive influence on willingness, the gap between knowledge and willingness was huge, with minimal registration influenced by the complex sociocultural constructs. Various sociocultural constructs such as family, fear and mistrust, religion, and bodily issues play a vital role. Differences were identified in willingness to donate and register between southern and other regions of India. Indian's organ donation behaviour in other geographical locations differed based on the socioreligious background of the country they lived in such as in Malaysia, Canada and the UK. However, they were collective in decision-making and had complex sociocultural interference irrespective of the country the individual lived which differed only in their next generations.

CONCLUSION:

Though this study showed the complex relationship, and its influences on organ donation behaviour, lacunae were identified to further understand how such complex interactions determine or inform the behaviour. Also, methodological issues were identified, where this particular population outside India were collectively studied with their neighbouring population which are not homogenous. Studies in India majorly addressed a similar aim using similar methods which produced repetition of studies leading to lack of diversified, wider and in-depth research. Therefore, while this systematic review addressed the barriers toward organ donation among Indians living globally, it also informs various gaps in research and also methodological issues.

AIM:

Pre-mortem interventions (PMIs) are performed on patients before the determination of death in order to preserve or enhance the possibility of organ donation. These interventions can be ethically controversial, and we thus undertook a scoping review of the ethical issues surrounding diverse PMIs.

METHODS:

Using modified scoping review methods, we executed a search strategy created by an information specialist. Screening and iterative coding of each article was done by two researchers using qualitative thematic analysis, and narrative summaries of coded themes were presented.

RESULTS:

We identified and screened 5365 references and coded 196 peer-reviewed publications. The most frequently cited issues were related to possible harms to the patient who is a potential donor, and legitimacy of consent. The most controversial issue was that PMIs may place patients at risk for physical harm, yet benefit is accrued mainly to recipients. Some authors argued that lack of direct medical benefit to the still living patient precluded valid consent from surrogate decision makers (SDMs), while many stated that some medical risk could be approved by SDMs if it aligns with non-medical benefits valued by the patient.

CONCLUSION:

PMIs require consensus that benefit includes concepts beyond medical benefit to the patient who is a potential donor. Informed consent must be confirmed for each PMI and not assumed to be part of general consent for donation. Risk must be proportionate to the potential benefit and newly proposed interventions should be reviewed carefully for medical efficacy and potential risks.

COVID-19 has been sweeping the globe, hitting the United States particularly hard with a state of emergency declared on March 13, 2020. Transplant hospitals have taken various precautions to protect patients from potential exposure. OPTN donor, candidate, and transplant data were analyzed from January 5, 2020 to September 5, 2020. The number of new waiting list registrations decreased, with the Northeast seeing over a 50% decrease from the week of 3/8 versus the week of 4/5. The national transplant system saw near cessation of living donor transplantation (-90%) from the week of 3/8 to the week of 4/5. Similarly, deceased donor kidney transplant volume dropped from 367 to 202 (-45%), and other organs saw similar decreases: lung (-70%), heart (-43%), and liver (-37%). Deceased donors recovered dropped from 260 to 163 (-45%) from 3/8 compared to 4/5, including a 67% decrease for lungs recovered. The magnitude of this decrease varied by geographic area, with the largest percent change (-67%) in the Northeast. Despite the pandemic, discard rates across organ has remained stable. Although the COVID-19 pandemic continues to evolve, OPTN data show recent evidence of stabilization, an indication that an early recovery of the number of living and deceased donors and transplants has ensued.

Conclusion: This is an interesting study addressing the need for biomedical and religious education in a particular population with lower support for organ donation than the US population overall. 337 participants received mosque-based education sessions on end-of-life care and organ donation and randomisation altered the order of the education sessions. At the start of the study 18% were registered as organ donors. The education program had a significant positive impact on participants knowledge of religious and biomedical issues related to organ donation. The project built community capacity for similar educational programmes in the future, but the workshops were time and resource intensive. Staff spent time identifying lecturers, recruiting participants and training peer educators.
Aims: This study aimed to determine whether a religiously tailored and ethically balanced educational intervention based in mosques was effective in increasing knowledge regarding kidney donation among Muslim Americans.
Interventions: Participants were randomised into two arms: the early arm, where the educational intervention on organ donation was received first, followed by an end-of-life care (control workshop) session; and the late arm, where the control workshop preceded the organ donation intervention.
Participants: 337 self-reported Muslims (≥18 years).
Outcomes: Changes in religious and biomedical knowledge regarding living organ donation.
Follow Up: 2 weeks

Biomedical and religious knowledge affects organ donation attitudes among Muslims. We tested the effectiveness of mosque-based, religiously tailored, ethically balanced education on organ donation among Muslim Americans. Our randomized, controlled, crossover trial took place at 4 mosques randomized to an early arm where organ donation education preceded a control educational workshop or a late arm with the order reversed. Primary outcomes were changes in biomedical (Rotterdam Renal Replacement Knowledge Test living donation subscale, R3KT) and religious (Islamic Knowledge of Living Organ Donation, IK-LOD) living kidney donation knowledge. Statistical analysis employed a 2 (Treatment Arm) X 3 (Time of Assessment) mixed-method analysis of variance. Of 158 participants, 59 were in the early arm and 99 in the late arm. A between group t test comparison at Period 1 (Time 1 - Time 2), demonstrated that the early arm had a significantly higher mean IK-LOD (7.11 v 5.19, P < .05) and R3KT scores (7.65 v 4.90, P < .05) when compared to the late arm. Late arm participants also had significant increases in mean IK-LOD (5.19 v 7.16, P < .05) and R3KT scores (4.90 v. 6.81, P < .05) postintervention (Time 2-Time 3). Our novel program thus yielded significant kidney donation-related knowledge gains among Muslim Americans (NCT04443114 Clinicaltrials.gov).

Organ donation saves lives and improves the quality of life. There is a shortage of organ donors worldwide. Behavior theories, such as the theory of planned behavior (TPB), help identify the antecedents of organ donation behavior and design effective interventions. The TPB suggests that intention is driven by constructs: attitude, subjective norm, perceived behavioral control (PBC), and intention. TPB can help improve organ donation behavior. This study aimed to analyze TPB-based interventions on Organ donation. Relevant studies were identified searching electronic databases, i.e., PubMed, Scopus, Science Direct, and Google Scholar from January 1, 2000 to February 30, 2020. None MeSH terms in title or abstract were searched, including: "theory of planned behavior*" and "Tissue donation" or "Tissue procurement" or "Organ procurement system" or "Organ procurement" or "Organ donation." Two authors independently reviewed the full texts and extracted all critical data from the included studies. Seventeen studies were assessed as having a reasonable methodology design. Studies show that TPB-based interventions can improve organ donation. Among TPB's constructs, PBC is the moderator and the determinant of organ donation behavior which its determination is different in different cultures. Attitude, subjective norms, moral norms, and anticipated regret should be considered in related interventions plus PBC. Increasing knowledge can facilitate organ donation behavior. Removing related cultural issues, removing fear due to misunderstanding of Brain death, improving trust, and improving moral values have effects on the behavior of organ donating.

Conclusion: The study aimed to compare the effect of theory-informed appeals for organ donation on donor registrations. Five advertisements that promoted organ donor registrations were randomly distributed through the Google advertising network. Advertisements were based on several behaviour change theories and were 1) control, 2) persuasive narrative, 3) social norm, 4) reciprocity and 5) knowledge related to the impact of organ donation. Advertisements were deployed for 3 days and resulted in over 5 million impressions. The control and reciprocity advertisements had the highest click-through rates and the social norm had the lowest click-through rate. There were 52 organ donor registrations but the registrations rate did not vary according to message type. The authors suggest that future research should aim to attract the attention of potential registrants through social networks and that the exact content of the message is less important.
Aims: This study aimed to investigate the effect of brief theory-informed visual appeals for organ donor registration that were disseminated online on commercial websites that used advertising banners.
Interventions: Participants were randomised to receive one of the following messages: a message containing a persuasive narrative about a transplant recipient, a message promoting the idea that registering as an organ donor was a social norm, a knowledge-based message communicating that a single donor could improve the lives of 50 people, a message on reciprocity offering a free organ donation wristband regardlesss of whether the participant was a registered organ donor, or a control message simply encouraging organ donation without additional information or any persuasive content.
Participants: Adults ≥ 18 years
Outcomes: The main outcomes of interest were the number of impressions and clicks, the click-through rate, the number of wristband orders, and the number and rate of organ donor registrations.
Follow Up: N/A
INTRODUCTION:

Many people do not register as organ donors. We developed 5 different brief appeals for organ donation that were disseminated online. The content was informed by theories of behavior change and studies of the specific cognitive barriers to organ donor registration.

METHODS:

One message was a persuasive narrative about a transplant recipient. Another message promoted the idea that organ donor registration is a social norm. The knowledge-based message communicated that 1 donor could improve the lives of 50 people. The message on reciprocity offered a free organ donation wristband, whether or not the participant registered as a donor. The message on control simply encouraged organ donation. Using Google AdWords, the messages were deployed randomly as banners of different sizes on diverse online sites and carried a link to an organ donor registration site. We measured clicks, page visits, and organ donor registrations.

RESULTS:

There were 5,156,048 impressions and 25,001 total clicks, a click-through rate of 0.49%. The messages on control and reciprocity both had the highest click-through rates of 0.51%. A total of 152 unique individuals requested wristbands and there were 52 total organ donor registration events. The message on reciprocity had the highest number of organ donor registrations (n = 18).

CONCLUSION:

Online organ donation messages rapidly generated substantial attention through clicks, but no message led to a meaningful number of organ donor registrations. Future research may focus on effectively capturing the attention of viewers through social networks or other convenient online venues with less competition for attention than Internet banners.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has rapidly become an unprecedented pandemic that has impacted society, disrupted hospital functions, strained health care resources, and impacted the lives of transplant professionals. Despite this, organ failure and the need for transplant continues throughout the United States. Considering the perpetual scarcity of deceased donor organs, Kates et al present a viewpoint that advocates for the utilization of coronavirus disease 2019 (COVID-19)-positive donors in selected cases. We present a review of the current literature that details the potential negative consequences of COVID-19-positive donors. The factors we consider include (1) the risk of blood transmission of SARS-CoV-2, (2) involvement of donor organs, (3) lack of effective therapies, (4) exposure of health care and recovery teams, (5) disease transmission and propagation, and (6) hospital resource utilization. While we acknowledge that transplant fulfills the mission of saving lives, it is imperative to consider the consequences not only to our recipients but also to the community and to health care workers, particularly in the absence of effective preventative or curative therapies. For these reasons, we believe the evidence and risks show that COVID-19 infection should continue to remain a contraindication for donation, as has been the initial response of donation and transplant societies.

The ongoing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has a drastic impact on national health care systems. Given the overwhelming demand on facility capacity, the impact on all health care sectors has to be addressed. Solid organ transplantation represents a field with a high demand on staff, intensive care units, and follow-up facilities. The great therapeutic value of organ transplantation has to be weighed against mandatory constraints of health care capacities. In addition, the management of immunosuppressed recipients has to be reassessed during the ongoing coronavirus disease 2019 (COVID-19) pandemic. In addressing these crucial questions, transplant physicians are facing a total lack of scientific evidence. Therefore, the aim of this study was to offer an approach of consensus-based guidance, derived from individual information of 22 transplant societies. Key recommendations were extracted and the degree of consensus among different organizations was calculated. A high degree of consensus was found for temporarily suspending nonurgent transplant procedures and living donation programs. Systematic polymerase chain reaction-based testing of donors and recipients was broadly recommended. Additionally, more specific aspects (eg, screening of surgical explant teams and restricted use of marginal donor organs) were included in our analysis. This study offers a novel approach to informed guidance for health care management when a priori no scientific evidence is available.
