Organ Transplantation Outcomes of Deceased Organ Donors in Organ Procurement Organization-Based Recovery Facilities Versus Acute-Care Hospitals

INTRODUCTION

Recovery of donated organs at organ procurement organization (OPO)-based recovery facilities has been proposed to improve organ donation outcomes, but few data exist to characterize differences between facilities and acute-care hospitals.

RESEARCH QUESTION

To compare donation outcomes between organ donors that underwent recovery procedures in OPO-based recovery facilities and hospitals.

DESIGN

Retrospective study of Organ Procurement and Transplantation Network data. From a population-based sample of deceased donors after brain death April 2017 to June 2021, donation outcomes were examined in 10 OPO regions with organ recovery facilities. Primary exposure was organ recovery procedure in an OPO-based organ recovery. Primary outcome was the number of organs transplanted per donor. Multivariable regression models were used to adjust for donor characteristics and managing OPO.

RESULTS

Among 5010 cohort donors, 2590 (51.7%) underwent recovery procedures in an OPO-based facility. Donors in facilities differed from those in hospitals, including recovery year, mechanisms of death, and some comorbid diseases. Donors in OPO-based facilities had higher total numbers of organs transplanted per donor (mean 3.5 [SD1.8] vs 3.3 [SD1.8]; adjusted mean difference 0.27, 95% confidence interval 0.18-0.36). Organ recovery at an OPO-based facility was also associated with more lungs, livers, and pancreases transplanted.

CONCLUSION

Organ recovery procedures at OPO-based facilities were associated with more organs transplanted per donor than in hospitals. Increasing access to OPO-based organ recovery facilities may improve rates of organ transplantation from deceased organ donors, although further data are needed on other important donor management quality metrics.

Medicine Faculty Students' Perspective On Cadaver And Organ Donation In The Covid-19 Pandemic

Background

Covid-19 is an important pandemic that affects the whole world. Another branch of the wreckage of the devastating effects on the health system is organ and cadaver donations. In this article, it was aimed to raise awareness about cadaver and organ donation in the covid-19 period, with the support of student opinions.

Methods

Twelfth phrases about cadaver and organ donation during covid-19 pandemic were presented to the fourth-,fifth-, and sixth-year students of the Kafkas University Faculty of Medicine. The answers were compared between male and female students using the chi-square test.

Results

It is seen that, the data from the study have been obtained about cadaver and organ donation is so impoartant. In addition, the storage conditions of cadavers and organs, the risk of disease transmission and the risk of contamination are discussed with striking data.

Conclusions

It is understood from the data obtained from this study that awareness about cadaver and organ donation is always on the agenda. In particular, conferences and meetings should be held frequently to inform medicine faculty students. The handling of the Covid-19 theme has also given a significant impetus to the research throughout.

Knowledge and attitude of organ donation in the Eastern region of Saudi Arabia and the influence of social media campaigns: a cross-sectional study

Previous studies showed organ donation to be less common in Arabic countries, and since there are not many studies exploring the perception toward organ donation, especially in the Eastern region of Saudi Arabia, this study aimed to assess the knowledge, attitude, and influence of social media campaigns on the willingness of organ donation.

Methods

A cross-sectional study was conducted between September 2021 and April 2022 among social media users through an Arabic online survey exploring the population's knowledge and attitude regarding organ donation and their willingness to donate. A total of 443 Saudi residents participated in the survey, with 376 of them meeting the required criteria.

Results

In all, 85% of participants of the study's calculated response rate were eligible to be included. One hundred ninety-eight of them (52.7%) were female, with age ranges between 18 and 29 years old (76.9%). The majority of the participants (63%) showed unwillingness to donate organs, with the highest rate among males (70.2%), aged above 30 (78.1%), and employees/students out of the healthcare sectors (69.5%). Inadequate knowledge was reported as the most common reason behind their rejection. Next to fears of operation and losing life, and the desire to donate to relatives only. Almost half of the participants (51.6%) agreed on the effect of social media on their behavior toward organ donation, with 187 of them (96.4%) referring to it as a positive effect which was significantly associated with the willingness to donate organs (P=0.006).

Conclusion

The study results showed that most of the participants have neither proper knowledge nor willingness toward organ donation. Therefore, more strategies could be developed to increase the rate of donation in the Eastern region.

Ethical considerations for theatre teams in organ donation after circulatory determination of death

Transplant surgery is an area that gives rise to a number of ethical considerations. As medicine continues to expand the boundaries of what is technically possible, we must consider the ethical implications of our interventions, not solely on patients and society, but also on those asked to provide that care. Here, we consider physician participation in procedures required to provide patient care in the context of the ethical convictions held by the physician, with an emphasis on organ donation after circulatory determination of death. Strategies that can be used to mitigate any potential negative impact on the psychological well-being of members of the patient care team are considered.

Potential of neonatal organ donation and outcome after transplantation

Organ transplantation is limited by access to suitable organs. Infant recipient waitlist mortality is increased due to the scarcity of size-matched organs. Neonatal organ donors have been proposed as an underutilized source of donor organs. However, the literature on the actual prevalence and outcome of neonatal organ donation and transplantation is fragmented and not well analyzed. This literature review aims to summarize the available literature on the potential of neonatal organ donation and to analyze published cases of neonatal organ transplantation. A systematic search of the Medline and Cochrane databases yielded 2964 articles, which were screened for eligibility. In total, 86 articles were considered eligible, of which 34 were included in the literature review: 8 articles describing the potential of neonatal organ donation programs, and 26 articles describing clinical transplantation. Current evidence suggests there is a large pool of potential neonatal organ donors. In contrast, the literature on neonatal organ donor utilization is sparse. However, case series of successful kidney, heart, liver, hepatocyte, and multivisceral transplantation using organs from neonatal donors are summarized. Although good posttransplant organ function was achieved, the use of neonatal organs is associated with increased risk of thrombosis in both kidney and liver transplantation. Neonatal organ donation is a promising alternative for expanding the current donor pool. Experience is limited, but reported patient and graft survival are acceptable and more research on the subject is warranted.

A Cross-Sectional Study of Professional Nurses' Knowledge, Attitudes, and Practices Regarding Organ Donation in Critical Care Units of Public and Private Hospitals in the Eastern Cape, South Africa

BACKGROUND

Globally, there is an overwhelming increase in the number of patients waiting for donated organs for transplantation, with a gross shortage of available organs. Lack of clear practice guidelines and the knowledge and attitudes of health care providers were hypothesized as possible reasons. We aimed to determine the attitudes, level of knowledge, and practices of professional nurses working in critical care units in public and private hospitals in Eastern Cape Province regarding organ donation.

METHOD

The study used a quantitative, non-experimental, descriptive design to investigate the current knowledge, attitude, and practice of organ donation in critical care among 108 professional nurses working in public and private critical care units in Eastern cape. Data were collected between 26 February 2017 until 27 June 2017 using anonymous, self-administered, pretested questionnaires. The means of knowledge, and practice scores were estimated among participants, and their associated categorical explanatory variables were ascertained.

RESULTS

A total of 108 nurses participated in the study. Of these, 94 (87.0%) were female, 78 (72.2%) were black, 104 (96.3%) were Christians, 79 (73.2%) worked in an ICU, 79 (73.2%) had a diploma qualification, and 67 (62.0%) worked in a tertiary hospital. About 67% of the respondents had good knowledge, 53% had a positive attitude, and 50.4% had poor practice readiness toward organ donation. Working in renal units (p < 0.001) and practicing in tertiary hospitals (p < 0.001) were significantly associated with a high organ donation knowledge score while being a female nurse (p = 0.036), working in renal units (p < 0.001), and practicing in tertiary hospitals (p < 0.001) were significantly associated with a high organ donation practice score.

CONCLUSION

Differences in organ donation knowledge and practices were noted between the different levels of health care services as the tertiary level outperformed the secondary level institutions. Nurses play a major role in critical and end-of-life care and are closer to patients and relatives. Hence, pre- and in-service education and promotional campaigns among nurses at all levels of care would be a strategic step to scale availability of donated organs and would meet the needs of thousands of individuals who need them to survive.

Organ Donation After Euthanasia in Patients Suffering From Psychiatric Disorders: 10-Years of Preliminary Experiences in the Netherlands

Euthanasia based on psychiatric suffering, followed by subsequent organ donation, is considered medically and legally permissible in the Netherlands. Although organ donation after euthanasia (ODE) in patients suffering from unbearable psychiatric illness is performed, it is not specifically addressed in the Dutch guideline on organ donation after euthanasia, and national data on ODE in psychiatric patients have not yet been published. In this article, the preliminary results of the 10-year Dutch case series of psychiatric patients who choose ODE are presented and potential factors influencing opportunities for donation in this population are discussed. We conclude that further future in-depth qualitative exploration of ODE in patients suffering from psychiatric illness and its associated ethical and practical dilemmas, including the consequences for the patient and their family and healthcare professionals, will be important to help make sense of potential barriers to donation for people undergoing euthanasia as a result of psychiatric suffering.

Organ donation: Key factors influencing the younger generation's decision-making in China

Background

The organ transplantation sector in China is facing a severe shortage of donors, and the organ donation rate needs to be increased. Since 2015, voluntary donation by citizens has become the only source of organs for transplantation in China. In recent years, there has been a relatively positive change in young people's attitudes toward organ donation after death. The aim of the study was to understand young people's perceptions and attitudes toward organ donation and the factors that influence them and can positively impact the promotion of organ donation.

Methods

By analyzing relevant literature and legal texts, we developed a questionnaire. Information was obtained through questionnaires and interviews, and 501 valid questionnaires were returned from the target group. A chi-square test was used to examine whether there were significant differences in the willingness to organ donation among young people with different characteristics. A factor analysis was used to investigate the main factors influencing the different attitudes of young people toward organ donation, and a one-way ANOVA was used to examine whether young people with different characteristics were affected differently by different factors.

Results

In our survey of young people aged 18-30 years, 99.2% of respondents knew about organ donation, 47.1% were willing to donate organs, and 15.2% understood that there were corresponding laws and regulations for organ donation. The study's findings showed that urban residents are more willing to be organ donators than rural residents; people with higher education levels have better awareness and are more willing to donate an organ; and people with religious beliefs are more likely to donate organs. The main factors that support the willingness of young people to donate are the social environment that provides support, their optimism in dealing with death, and their desire to realize their final value after death. The main factors for those unwilling to donate were low awareness or misconceptions about organ donation among individuals and their families and their attitudes toward death. As the people who took the questionnaire are probably interested in organ donation, the sample results will show a higher percentage of people who know about organ donation. We hope to discuss further with a larger and broader sample coverage to improve the estimates' validity and reflect the overall picture more accurately in a future study.

Conclusion

Young people knew about organ donation but had a low depth of awareness. Household registration type, education level, and religious affiliation significantly correlate with people's willingness to donate. The supportive environment for organ donation in society and the correct understanding of the organ donation process and laws and regulations can influence people's willingness to donate.

Factors influencing organ donation in Fujian's Organ Procurement Organization: A retrospective study

INTRODUCTION

The Organ Procurement Organization (OPO) was established in August 2018. The organization's workload, work efficiency, and quality control of organ donation and procurement have continuously improved, making it one of the most successful OPOs in Fujian Province. This study explores the factors that influence the success and failure of organ donation in Fujian Province, China.

METHODS

Data from 236 potential organ donors registered at an OPO in Fujian Province between January 2020 and May 2022 were retrospectively analyzed.

RESULTS

Among the 236 potential organ donors, 71 cases of organ donation were successful (30.08% conversion rate). Univariate analysis showed that demographic factors, such as differences in sex, age, marital status, and domicile location, were significantly associated with successful organ donation (p < .05). Among hospital-related factors, differences in hospital departments were significant (p < .05). Considering disease-related factors, spontaneous respiration was significant (p < .05). For factors related to organ donation, differences in coordinators were significant (p < .05). Multivariate analysis showed that age, domicile location, spontaneous respiration, and coordinators influenced organ donation success (p < .05). Multifactor analysis revealed that factors, such as age ≤50 years, domicile location in other provinces, no spontaneous respiration, and highly skilled coordinators, could promote successful organ donation.

CONCLUSIONS

Programs should clarify the screening criteria for key potential organ donors, enhance the promotion and popularization of organ donation, and boost the number and professional skills of organ donation coordinators to improve the organ donation conversion rate.

Trends in organ donation and transplantation over the past eighteen years in Iran

BACKGROUND

This article will review the trends in organ donation over the past 18 years in Iran.

MATERIAL AND METHODS

All donation and transplantation statistics were extracted by reviewing the Organ Procurement and Transplantation database of the Ministry of Health of Iran from 2002 to 2019.

RESULTS

Iran's national deceased donation rate from 2002 to 2019 increased 19.06-fold from .75 to 14.3 per million population (PMP). After the beginning of the COVID-19 pandemic, the rate of organ donation in Iran decreased significantly. Although 1 year after the onset of the pandemic, due to the widespread adoption of COVID19 vaccination, the rate of organ donation began to increase again, this system is still under performing. During the years under examination, the rate of deceased kidney donation increased significantly compared to living kidney donation and reached up to 2001 kidney transplantations in 2021. From 2002 to 2019, the rate of liver transplants increased to 12.8. Likewise, the rate of heart transplants increased 8.4-fold, from 15 to 126 cases during the same time.

CONCLUSSION

Although a personal choice, the process of organ donation involves medical, legal, ethical, organizational, and social aspects. The trend in increasing donation rates over the past years can be attributed to multiple influences, which include rigorous team efforts in the organ donation and transplantation systems, in addition to creating a donation culture and promoting donation through media platforms. Moreover, we can say that the rising rates of deceased donor transplantation also can drive down rates of commercial living donor transplantation.

Organ Donation after Extracorporeal Cardiopulmonary Resuscitation and Brain Death

A 38-year-old primipara Japanese woman suffered cardiac arrest due to a pulmonary thromboembolism 1 day after undergoing a cesarean section. Extracorporeal cardiopulmonary resuscitation was initiated and extracorporeal membrane oxygenation support was needed for 24 h. Despite intensive care, the patient was diagnosed with brain death on day 6. With the family's consent, comprehensive end-of-life care including organ donation was discussed based on our hospital's policy. The family decided to donate her organs. Specific training and education are required for emergency physicians to optimize the process of incorporating organ donation into end-of-life care while respecting the patient's and family's wishes.

Nurse knowledge and attitudes towards organ donation and deemed consent: the Human Organ and Tissue Donation Act in Nova Scotia

PURPOSE

In April 2019, the Human Organ and Tissue Donation Act (HOTDA) in Nova Scotia was modified to incorporate a deemed consent model. In this study, we sought to understand intensive care unit (ICU) and emergency department (ED) nurses' knowledge of and confidence around organ donation and transplantation, experiences with organ donors and recipients, attitudes toward organ donation and deemed consent, and perceived opportunities and barriers to a deemed consent approach in view of the legislative change.

METHODS

We sent an electronic, self-administered survey to all ICU and ED nurses in Nova Scotia. The survey queried respondents on their knowledge of, experience with, and attitudes around organ donation and HOTDA, and opportunities and barriers to the implementation of HOTDA in clinical practice. Survey results were analyzed using descriptive statistics.

RESULTS

One-hundred and ninety-four nurses responded to the survey. Nearly all (98%) supported organ donation, with 86% having signed an organ donor card to donate organs and/or tissues after death. A considerable majority (89%) also supported the new legislation. Nevertheless, a minority of respondents (13%) believed that deemed consent legislation would be considered a violation of the general principles of freedom and autonomy. The three most identified topics for ongoing training were coordination of the donation process (70%), clinical management of donors (70%), and family issues in decision-making (70%).

CONCLUSION

Intensive care unit and ED nurses had positive attitudes toward organ donation, including deemed consent model. The findings should inform educational initiatives in Nova Scotia and beyond to optimize organ donation processes and outcomes.

Perception of college-going girls towards corneal donation in North India: A latent class analysis study

Purpose

To assess the perception of college-going girls toward corneal donation in Northern India.

Methods

An online survey with a pre-structured, pre-validated questionnaire was conducted on 1721 college-going girls in Northern India. The knowledge and attitude scores were regressed, and latent class analysis was carried out.

Results

The average of scores for all participants was computed individually for the knowledge questions and the attitude questions, and based on this score, total participants were divided into two groups: Better corneal donation behaviors (BCDB) and poor corneal donation behaviors. The binomial logistic regression model of knowledge domain for predicting BCDB, age of the participant, their awareness about corneal donation, and willingness to discuss eye donation among family members were found significant. Similarly, for the attitude domain, awareness about corneal donation, knowledge about hours within which ideal eye donation needs to be undertaken, and knowledge about eye donation during coronavirus disease 2019 (COVID-19) pandemic were found to be significant. Latent class analysis identified one subset of participants having poorer knowledge and attitude scores and that they were more from a rural background, were having more than first order as birth order, were belonging to SC/ST classes, had illiterate or secondary education of father and mother, and were living in rented houses.

Conclusion

The findings of the study significantly contribute to devising a mechanism to improve knowledge and influencing the attitude about eye donation among the youth, especially young women, who can act as counselors and motivators for the masses as well as their own families, in the generations to come.

The 20-year paradigm shift toward organ recovery centers: 2500 donors at Mid-America Transplant and broader adoption across the United States

On March 1, 2001, Mid-America Transplant, the organ procurement organization (OPO) located in St Louis, Missouri, performed the first organ recovery of a brain-dead donor in a hospital-independent, free-standing, organ recovery center (ORC), with successful transplantation of a liver. This was the inception of a paradigm shift in donor management and organ procurement, moving away from the traditional method of using the donor hospital. In the last 20 years, many advances have occurred in the ORC. Brain-dead donors are moved within hours of authorization to fully equipped intensive care units. Some ORCs are equipped with computed tomography scanners, portable radiography, laboratory facilities, bronchoscopy, and a cardiac catheterization laboratory. ORCs have dedicated surgical suites, and operating time is frequently during the day and is rarely delayed. Donor management in an ORC is more consistent, efficient, and effective than that in a donor hospital, and studies have demonstrated increased organ yield. Multiple studies have demonstrated a cost benefit of an ORC as well as providing an ideal environment for donor research studies. Currently, there are 24 of 57 OPOs that are using an independent or hospital-based ORC to manage their donors. We review the history and describe the current state of ORCs.

"Train the Trainers" Program to Improve Knowledge, Attitudes and Perceptions About Organ Donation in the European Union and Neighbouring Countries: Pre- and Post- Data Analysis of the EUDONORGAN Project

EUDONORGAN, a European Union-funded project to improve organ and tissue donation, included a blended-based "Train the Trainers" program, which was implemented with the support of an international consortium from Croatia, Italy, Slovenia, and Spain. The web-based training included seven modules for which medical aspects, educational tips, and practical activities were scored using a 5-point Likert scale. The overall mean scores of satisfaction were higher than 4 for each module, without significant differences between HCPs and OKPs. In the face-to-face training survey similar scores above 4 were obtained for most items. Knowledge acquisition improved significantly in both HCPs and OKPs, as well as in transplant/donor coordinators, medical doctors, registered nurses, anesthesiologists/intensivists, and intensive care nurses. Improvements in attitudes and perceptions regarding organ donation were also observed, particularly among HCPs. In the accomplishment of the learning process, a successful pass mark of 95% was obtained. The "Train the Trainers" program was associated with an improvement in learning and attitudes of healthcare and non-healthcare professionals for the benefit of organ and tissue donation.

Challenges and Motivators to Organ Donation: A Qualitative Exploratory Study in Gujarat, India

Purpose

Despite the global efforts to improve organ donation, there is a demand-supply gap for organs in India. The only solution to meet this disparity is to improve deceased donor transplants in the country through victims of road accidents. The government has instituted several initiatives to achieve this goal. However, challenges and barriers continue to affect the organ donation process. The present study aims to document the motivating factors and obstacles in the decision of families to donate organs in Ahmedabad, Gujarat and their suggestions to improve the processes involved in organ donation.

Patients and Methods

A qualitative exploratory study (in-depth interview) of ten relatives of deceased organ donors was conducted from Oct 2021 to Feb 2022. Interviews were audio recorded, and detailed notes were taken during the interview. Thematic analysis was done using ATLAS.ti version 8 software.

Results

The significant motivators identified were family members' belief or conviction that it would help save the lives of others; a sense of moral obligation to do so as bodies of brain-dead persons can contribute to this noble goal, no use of the body after death, an extension of life, and being a role model for others. The challenges were mistrusting the organ donation process, fear of being responsible for any mishappening, and feeling of shock. The suggestions to improve organ donation included awareness creation, simplifying the legal process for accidental deaths, providing benefits to the donor family, and a system for identifying potential donors and their counselling.

Conclusion

The present study reflects the need for a more comprehensive awareness campaign to generate awareness and remove the misconception about organ donation in India. The findings of the study can be helpful for policymakers to amend the current organ donation process in India and improve the disequilibrium of demand and supply of deceased donations in India.

The impact of donor consent mechanism on organ procurement organization performance in the United States

BACKGROUND

Lack of donor organ availability represents a major limitation to the success of solid organ transplantation. The Scientific Registry of Transplant Recipients (SRTR) publishes performance reports of organ procurement organizations (OPO) in the United States, but does not stratify by the mechanism of donor consent, namely first-person authorization (organ donor registry) and next-of-kin authorization. This study aimed to report the trends in deceased organ donation in the United States and assess the regional differences in OPO performance after accounting for the different mechanisms of donor consent.

METHODS

The SRTR database was queried for all eligible deaths (2008-2019) which were then stratified based on the mechanism of donor authorization. Multivariable logistic regression was performed to assess the probability of organ donation across OPOs based on specific donor consent mechanisms. Eligible deaths were divided into 3 cohorts based on the probability to donate. Consent rates at the OPO level were calculated for each cohort.

RESULTS

Organ donor registration among adult eligible deaths in the U.S. increased over time (2008: 10% vs 2019: 39%, p < 0.001), coincident with a decline in next-of-kin authorization rates (2008: 70% vs 2019: 64%, p < 0.001). At the OPO level, the increased organ donor registration was associated with lower next-of-kin authorization rates. Among eligible deaths with medium- and low-probability of donation, recruitment was highly variable across OPO's, ranging from 36% to 75% in the medium-probability group (median 54%, IQR 50%-59%) and 8% and 73% in the low-probability group (median 30%, IQR 17%-38%).

CONCLUSION

Significant variability exists across OPOs in the consent of potentially persuadable donors after adjusting for population demographic differences and the mechanism of consent. Current metrics may not truly reflect OPO performance as they do not account for consent mechanism. There is further opportunity for improvement in deceased organ donation through targeted initiatives across OPOs, modeled after regions with the best performance.

A machine-learning approach to estimating public intentions to become a living kidney donor in England: Evidence from repeated cross-sectional survey data

Background

Living kidney organ donors offer a cost-effective alternative to deceased organ donation. They enable patients with life-threatening conditions to receive grafts that would otherwise not be available, thereby creating space for other patients waiting for organs and contributing to reducing overall waiting times for organs. There is an emerging consensus that an increase in living donation could contribute even more than deceased donation to reducing inequalities in organ donation between different population sub-groups in England. Increasing living donation is thus a priority for National Health Service Blood and Transplant (NHSBT) in the United Kingdom.

Methods

Using the random forest model, a machine learning (ML) approach, this study analyzed eight waves of repeated cross-sectional survey data collected from 2017 to 2021 (n = 14,278) as part of the organ donation attitudinal tracker survey commissioned by NHSBT in England to identify and help predict key factors that inform public intentions to become living donors.

Results

Overall, around 58.8% of the population would consider donating their kidney to a family member (50.5%), a friend (28%) or an unknown person (13.2%). The ML algorithm identified important factors that influence intentions to become a living kidney donor. They include, in reducing order of importance, support for organ donation, awareness of organ donation publicity campaigns, gender, age, occupation, religion, number of children in the household, and ethnic origin. Support for organ donation, awareness of public campaigns, and being younger were all positively associated with predicted propensity for living donation. The variable importance scores show that ethnic origin and religion were less important than the other variables in predicting living donor intention.

Conclusion

Factors influencing intentions to become a living donor are complex and highly individual in nature. Machine learning methods that allow for complex interactions between characteristics can be helpful in explaining these decisions. This work has identified important factors and subgroups that have higher propensity for living donation. Interventions should target both potential live donors and recipients. Research is needed to explore the extent to which these preferences are malleable to better understand what works and in which contexts to increase live organ donation.

Examining behavioural intention towards organ donation in Hong Kong

Although many people report favourable attitudes towards organ donation, Hong Kong has one of the lowest rates of organ donation globally. The present study examined behavioural intention towards organ donation. A convenience sample of 225 Hong Kong Chinese adults (118 = female) aged 18-82 years were recruited to an online survey. Behavioural intention, attitudes, subjective norms, self-efficacy, knowledge and altruism were examined. ANOVA was conducted to examine key differences based on behavioural intention, regression then examined predictors of behavioural intention to donate before exploratory analysis examined the mediating role of subjective norms on the relationship between self-efficacy and behavioural intention. Findings revealed over one third (38%) of respondents were actively registered as organ donors. Women were significantly more likely to be registered as organ donors. Subjective norms and self-efficacy were strong predictors of behavioural intention to donate, and subjective norms significantly mediated the relationship between self-efficacy and behavioural intention to donate.

End-Of-Life Care in the Potential Donor after Circulatory Death: A Systematic Review

Background

Donation after circulatory death (DCD) is becoming increasingly common, yet little is known about the way potential donors receive end-of-life care.

Purpose

The aims of this systematic review are to describe the current practice in end-of-life care for potential donors and identify metrics that are being used to assess discomfort among these patients.

Research design and Study Sample

This review encompasses published literature between June 1, 2000 and June 31, 2020 of end-of-life care received by potential DCD patients. The population of interest was defined as patients eligible for Maastracht classification III donation after circulatory death for a solid organ transplantation. Outcomes examined included: analgesic or palliative protocols, and surrogates of discomfort (eg dyspnea, agitation).

Results

Among 141 unique articles, 27 studies were included for full review. The primary reason for exclusion was lack of protocol description, or lack of reporting on analgesic medications. No primary research studies specifically examined distress in the DCD eligible population. Numerous professional guidelines were identified. Surveys of critical care practitioners identified concerns regarding the impact of symptom management on hastening the dying process in the DCD population as a potential barrier to end-of-life palliative treatment.

Conclusions

There is a paucity of empirical evidence for end-of-life symptom assessment and management for DCD patients. Key evidence gaps identified for DCD include the need for: i) a multidisciplinary structure of treatment teams and preferred environment for DCD, ii) objective tools for monitoring of distress in this patient population, and iii) evidence guiding the administration of analgesic medications following withdrawal of life sustaining therapy.

The portrayal of organ donation on TikTok: A content analysis of popular English-language TikTok videos

Objective

TikTok is one of the most popular social media platforms and plays a role in shaping public perceptions. This research examined how organ donation was portrayed on the platform.

Methods

We built a dataset of the most popular English-language TikTok videos that used the hashtags #organdonor or #organdonation. We then performed content analysis on the 400 most viewed videos after limiting data set inclusion to one video per user account.

Results

The finalized videos (N = 313) had generated nearly 80 million views and 10 million likes. Featuring both donors (56.2%) and recipients (44.1%), videos shared experiences that celebrated and lamented lost donor lives (41.8%) while also celebrating transplantation successes (31.3%). Very few videos included public solicitation (2.9%). Common video traits included detailing medical procedures (45.4%), presenting honor walks (10.9%), and displaying donors and recipients connecting or wanting to connect (16.9%). Videos mostly had a positive (74.1%) versus negative (10.2%) leaning tone.

Conclusion

Far from superficially glamorizing organ donation/transplantation processes and procedures, popular English-language TikTok videos depicted what we perceived as highly emotional and expository experiences. While the videos likely offered learning and cathartic opportunities for individuals and communities, they also highlight some tensions between personal anecdotes and data/research. Findings from this research can inform public outreach efforts as well as policies related to protecting anonymity and celebrating donors with honor walks. Indeed, given TikTok's increasing popularity and influence, it could be a valuable tool to meaningfully learn from, and engage with, patient and donor communities.

The Legal Void Outside Brain Death in India: The Legislative Need of 'DNR' in Brain Death

Objective

The legal definitions of brain death are tantamount for legal dogmas and sometimes criminal intimidation of the treating doctors. The tests for brain death are only applicable to patients planned for organ transplantation. We intend to discuss the necessity of the "Do Not Resuscitate (DNR)" legislature in cases of brain death patients and applicability of tests for brain death irrespective of the intention for organ donation.

Methods

A comprehensive review of the literature was performed till May 31, 2020 from the MEDLINE (1966 to July 2019) and Web of Science (1900 to July 2019). Search criteria included all publications with the MESH terms: "Brain Death/legislation and jurisprudence"[Mesh] OR "Brain Death/organization and administration"[Mesh] AND "India" [Mesh]. We also discuss the different opinions and implications of brain death versus brain stem death in India with the senior author (KG) who was responsible for South Asia's first multi-organ transplant after certifying brain death. Additionally, a hypothetical scenario of a DNR case is discussed in the current legal paradigm of India.

Results

The systematic search yielded only five articles reporting a series of brain stem death cases with an acceptance rate of organ transplant among brain stem deaths being 34.8%. The most common solid organs transplanted were the kidney (73%) and liver (21%). A hypothetical scenario of a DNR and possible legal implications of the same under the current 'Transplantation of Human Organs Act (THOA)' of India remains unclear. A comparison of brain death laws in most Asian countries shows a similar pattern regarding the declaration of brain death and the lack of knowledge or legislature regarding DNR cases.

Conclusion

After the determination of brain death, discontinuation of organ support requires the consent of the family. The lack of education and the lack of awareness have been major impediments in this medico-legal battle. There is also an urgent need to make laws for cases that do not qualify for brain death. This would help in not only realistic realization but also better triage of the health care resources while legally safeguarding the medical fraternity.

Social Media and Organ Donation: Pros and Cons

Shortage of organ donors is the most important obstacle standing in the way of lifesaving organ transplantation in a myriad of patients suffering from end-stage organ failure. It is vital that the transplant societies and associated appropriate authorities develop strategies to overcome the unmet needs for organ donation. The power of prominent social media (SoMe) platforms such as Facebook, Twitter, and Instagram, which reach millions of people, can increase awareness, provide education, and may ameliorate the pessimism toward organ donation among the general population. Additionally, public solicitation of organs may be helpful for waitlisted candidates for organ transplantation, who cannot find a suitable donor among near relations. However, the use of SoMe for organ donation has several ethical issues. This review attempts to highlight the advantages and limitations of using social media in the context of organ donation for transplantation. Some suggestions on the best utilization of social media platforms for organ donation while balancing ethical considerations have been highlighted here.

Altruism in death: Attitudes to body and organ donation in Australian students

Health education, research, and training rely on the altruistic act of body donation for the supply of cadavers. Organ transplantation and research rely on donated organs. Supply of both is limited, with further restrictions in Australia due to requirements for a next-of-kin agreement to donation, irrespective of the deceased's pre-death consent. Research suggests health workers are less likely to support the donation of their own bodies and/or organs, despite recognizing the public good of donation, and that exposure to gross anatomy teaching may negatively affect support for donation. Attitudes to body and organ donation were examined in Australian students studying anatomy. Support for self-body donation (26.5%) was much lower than support for self-organ donation (82.5%). Ten percent of participants would not support the election of a family member or member of the public to donate their body, and just over 4% would not support the election of a family member to donate their organs, with one-to-two percent not supporting this election by a member of the public. Exposure to gross anatomy teaching was associated with an increased likelihood of consideration of issues about body and organ donation, whether for self, family, or the public, and registration as an organ donor. Exposure decreased participants' willingness to donate their own body, with those who practiced a religion least likely to support body donation. Gross anatomy courses provide an opportunity to inform future healthcare workers about altruistic donation, albeit with a recognition that religious or cultural beliefs may affect willingness to donate.

Changes in Awareness Toward Minor's Organ Donation Through Structured Information; Survey

This study analyzed survey results regarding awareness of living minors' organ donation. The questionnaires focused on changes in how respondents felt about donations by living minors after eliciting the uncertainty of long-term outcomes for living donors and recipients. The respondents were categorized as minors, adults affiliated with non-medical jobs (Non-Meds), and adults affiliated with medical jobs (Meds). The rates of awareness of living organ donation were significantly different; minors at 86.2%, non-Meds at 82.0%, and Meds at 98.7% (p < 0.001). Only 41.4% of Minors and 32.0% of Non-Meds were aware of organ donation by minors, while 70.3% of Meds were (p < 0.001). The response rate of opposition to organ donation by minors was highest for Meds and remained the same before and after (54.4%-57.7%, p = 0.311). However, the opposition rate in Non-Meds significantly increased (32.4%-46.7%) after learning about the uncertainty of long-term outcomes (p = 0.009). The study found that Non-Meds lacked adequate knowledge regarding organ donation by minors and their potential lethal outcomes. Their attitudes toward organ donation by minors could be changed by giving structured information. It is necessary to provide exact information and raise social awareness regarding organ donation by living minors.

Impacts of the COVID-19 pandemic on a human research islet program

Designated a pandemic in March 2020, the spread of severe acute respiratory syndrome virus 2 (SARS-CoV2), the virus responsible for coronavirus disease 2019 (COVID-19), led to new guidelines and restrictions being implemented for individuals, businesses, and societies in efforts to limit the impacts of COVID-19 on personal health and healthcare systems. Here we report the impacts of the COVID-19 pandemic on pancreas processing and islet isolation/distribution outcomes at the Alberta Diabetes Institute IsletCore, a facility specializing in the processing and distribution of human pancreatic islets for research. While the number of organs processed was significantly reduced, organ quality and the function of cellular outputs were minimally impacted during the pandemic when compared to an equivalent period immediately prior. Despite the maintained quality of isolated islets, feedback from recipient groups was more negative. Our findings suggest this is likely due to disrupted distribution which led to increased transit times to recipient labs, particularly those overseas. Thus, to improve overall outcomes in a climate of limited research islet supply, prioritization of tissue recipients based on likely tissue transit times may be needed.

Organ Donation From Patients on Extracorporeal Membrane Oxygenation at the Time of Death

To describe the clinical characteristics and organ donation rate of patients supported by extracorporeal membrane oxygenation (ECMO) at the time of death.

DESIGN

Retrospective observational study. Pearson chi-square and Fisher exact tests were used in statistical analyses.

SETTING

One hundred twenty-seven acute care hospitals in New Jersey, Pennsylvania, and Delaware.

PATIENTS

Adult and pediatric patients who were on ECMO at the time of referral to a large organ procurement organization (OPO) between 2016 and 2020.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Nineteen thousand nine hundred thirty patients were referred to the OPO between November 2016 and September 2020, of which 5,034 were medically suitable potential donors. Of this cohort, 143 patients were supported on ECMO at the time of OPO referral and 141 were included in analyses (median age 47 yr, 60% male). Thirty-three percent (46/141, median age 48 yr, 52% male) donated organs, compared with 50% of non-ECMO patients (p ≤ 0.0005). ECMO and non-ECMO patients had organs recovered but not transplanted at similar rates (11% vs 10%, p = 0.8). There were no significant differences in sex (p = 0.16) or ethnicity (p = 0.50) between organ donor and nondonor groups. Fifty-one percent (21/41) of organ donors donated after circulatory death and 49% (20/41) after brain death. Patients declared dead by neurologic criteria were more likely to donate (51%) than those declared dead by circulatory criteria (21%, p < 0.001). Frequency of cardiac arrest prior to ECMO was similar between donors and nondonors (p = 0.68). Thirty-nine percent (16/41) of donors had an out-of-hospital cardiac arrest (OHCA) and 51% (21/41) were cannulated via extracorporeal cardiopulmonary resuscitation (ECPR). The most common reason patients were not donors was that family declined (57%).

CONCLUSIONS

One-third of patients referred to the OPO on ECMO at the time of death donated organs. While donation occurred less frequently after ECMO, ECMO and non-ECMO patients had organs used rather than discarded at a similar rate. Patients successfully donated following OHCA and/or ECPR. Clinicians should not consider ECMO a barrier to organ donation.

Ethical issues of organ donation after circulatory death: Considerations for a successful implementation in Chile

Organ transplantation is a lifesaving procedure for end-organ damage and remains up to today as the most cost-effective alternative to treat these conditions. However, the main limitation to performing organ transplants is the availability of donor organs suitable for transplantation. To increase the donor pool, expanding organ donation from the conventional neurologic determination of death (NDD) to include circulatory determination of death (DCD) has been a well-established method of increasing donors in other countries. In this article, we discuss the clinical and ethical considerations for introducing DCD in Chile. The concepts we have used could very well be translatable to other similar countries which have not implemented this donation system yet. The most relevant issue to date is that DCD needs to alter the care of dying patients to obtain quality donor organs. In some countries, including Chile, there are some cultural barriers regarding withdrawal-of-care. These barriers include confusing withdrawal of care with acceleration of death, which leads to many practitioners refusing to remove artificial life support, and in turn only minimize ventilatory support or switch to a T-tube (without extubation). This cultural barrier could be overcome with careful consideration of the opinions of healthcare workers, family members, community and policy-based stakeholders. We also identified ethical issues related to informed consent of both donor and recipients, among other relevant ethical considerations. In conclusion, DCD donation in Chile can increase organ donation numbers in one of Latin America's countries with the lowest effective donor rate. However, this opportunity must be taken with caution to avoid the opposite effect if this policy is not well implemented, respecting the sound ethical principles mentioned in this paper.

Evaluating predicted heart mass in adolescent heart transplantation

BACKGROUND

Predicted Heart Mass (PHM) has emerged as an attractive size matching metric in adult cardiac transplantation. However, since PHM was derived from a healthy adult cohort, its generalizability to the pediatric population is unclear. We hypothesize that PHM can be extended to older adolescents, and potentially broaden the donor pool available to this group.

METHODS

The United Network for Organ Sharing database was retrospectively analyzed for patients aged 13 to 18 undergoing heart transplantation. Recipients were divided into quintiles (Q1-Q5) based on donor-to-recipient predicted heart mass ratios (PHMR). Primary end-point was graft survival at 5 years.

RESULTS

Two thousand sixty-one adolescent heart transplant recipients between January 1994 and September 2019 were retrospectively analyzed. The median PHMR's for each quintile was 0.84 (0.59-0.92), 0.97 (0.92-1.02), 1.08 (1.02-1.14), 1.21 (1.14-1.30), and 1.44 (1.30-2.31). Kaplan-Meier survival curves demonstrated comparable survival across all quintiles of PHMR (p = 0.9). Multivariate Cox regression showed no significant difference in graft failure of the outer quintiles when compared to the middle quintile (Q1: 1.04 HR, p = 0.80; Q2: 1.02 HR, p = 0.89; Q4: 1.19 HR, p = 0.28; Q5: 1.02 HR, p = 0.89). Significant covariates included transplant year (HR: 0.95, p < 0.0001), serum bilirubin (HR: 1.04, p = 0.0004), ECMO at transplantation (HR: 2.85, p < 0.0001), and underlying diagnosis of dilated cardiomyopathy (vs congenital heart disease, HR: 0.66, p = 0.0004).

CONCLUSIONS

Matching by PHM is not associated with survival or risk in adolescent heart transplant recipients. Our results underscore the ongoing need to develop an improved size-matching method in pediatric heart transplantation.

Analysis of content and online public responses to media articles that raise awareness of the opt-out system of consent to organ donation in England

Background

Preceded by a national media campaign, in May 2020, England switched to a soft opt-out system of organ donation which rests on the assumption that individuals meeting specific criteria have consented to organ donation unless they have expressed otherwise. We aimed to learn more about how the changes were communicated, how people responded and any discrepancies between key messages and how they were interpreted by the public.

Methods

Summative content analysis of 286 stories and related reader-generated comments in leading UK online news sources (April 2019 to May 2021). Further detailed thematic analysis of 21 articles with reader-generated content, complemented by thematic content analysis coding of all 286 stories.

Results

Most media coverage on both organ donation and the law change was positive, with little variation over time or between publications. The importance of organ donation, benefits of the law change, and emotive stories (often involving children) of those who had donated an organ described as "superheroes" or those who had received organs as benefiting from a "miracle" were frequently cited. In contrast, reader-generated comments were markedly more negative, for example, focusing on loss of individual freedom and lack of trust in the organ donation system. Commentators wished to be able to choose who their organs were donated to, were dismissive and blaming towards minority ethnic groups, including undermining legitimate worries about the compatibility of organ donation with religious beliefs and end of life cultural norms, understanding and acceptance of brain-stem death and systemic racism. Misinformation including use of inflammatory language was common.

Conclusion

The portrayal of donors and recipients as extraordinary is unlikely to help to normalise organ donation. Undermining legitimate concerns, in particular those from ethnic minorities, can alienate and encourage harmful misinformation in underrepresented groups. The discrepancies between the tone of the articles and the readers comments suggests a lack of trust across the public, health, policy and media outlets. Easily accessible, ongoing and tailored sources are needed to mitigate misinformation and disinformation and ensure key messages are better understood and accepted in order to realise the ambitions of soft opt-out organ donation policies.

Living Liver Donation Does not Significantly Affect Long-Term Life, Disability, or Medical Insurability

INTRODUCTION

The growing practice of living liver donation requires comprehensive understanding of the financial implications for living liver donors. While obtaining and maintaining insurance is important to financial health, little is known about the impact of liver donation on future insurability.

RESEARCH QUESTIONS

The purpose of this study was to evaluate the donors' experiences with insurance following donation and identify the insurance provider-driven factors that contribute to donor insurability.

DESIGN

A two center cohort of living donors with donation between January 2000 and December 2018 (N = 442) were surveyed about postdonation insurance experiences. To understand insurance provider practices towards liver donors, life (n = 11) and disability (n = 4) insurance underwriters were asked to provide policy quotes for a standardized living liver donor profile.

RESULTS

Responses (N = 101) were received by August 2020 (response rate = 22.9%). Living liver donors reported owning life (58%), disability (35%), and medical (87%) insurance at rates comparable to the general population with low proportions reporting difficulty obtaining these insurance types (9%, 9%, 4%, respectively). Post-donation life insurance ownership was associated with post-donation employment (P = 0.01). Underwriter responses indicate life and disability insurability were adversely affected up to 12 months following donation.

CONCLUSIONS

Living liver donors did not have difficulty maintaining insurance in the long-term but should be counseled to purchase insurance prior to surgery as short-term insurability may be affected. Perception of difficulty obtaining insurance following donation remains of significant concern among living donors. Further collaboration between the transplant community and insurance companies is warranted.

Level and determinants of willingness to donate organs among the general public: A cross-sectional survey in China

This study aims to assess the level and determinants of the general public's willingness to organ donation. We conducted a population-based cross-sectional study of 4261 participants in China. The primary outcome was the willingness to donate organs. Logistic regression modelling was used to determine the factors that affect willingness to donate organs. Overall, the proportion of participants who showed a willingness to donate organs was 47.45% (95%CI: 0.46, 0.49) in this study. Logistic regression modelling showed participants from Western (OR = 1.33, 95%CI = 1.11-1.59) and Eastern China (OR = 1.40, 95%CI = 1.19-1.65) were more willing to donate organs compared with those from Central China. The odds of being willing to donate organs was higher in females than males (OR = 1.35, 95%CI = 1.17-1.55); and was higher in those participants with experience of organ donation (OR = 1.58, 95%CI = 1.13-2.21), experience of caring for organ transplant patients (OR = 1.45, 95%CI = 1.01-2.07), and those undertaking related voluntary activities (OR = 1.67, 95%CI = 1.45-1.94), than those without. The general public's level of willingness to organ donation was not high in this study. Geographical region, gender, experience of organ donation related activities, taking care of organ transplant patients and volunteering in related activities were independently associated with participants' willingness to donate organs.

Policies and Price Tags: The Public's Perception of Face Transplantation and Its Funding

Study Design

Survey study.

Objective

Facial vascularized composite allotransplantation (FVCA) can cost over 1 million dollars per procedure and is usually not covered by insurance, yet this financial burden and public opinion surrounding this procedure are not well understood. This study is the first to evaluate the layperson's opinions on the allocation of financial responsibility for FVCA and its inclusion in organ donation registries.

Methods

Eight hundred and fifteen laypersons were surveyed through MTurk to assess their agreement with 11 statements about FVCA perceptions, funding, and inclusion on organ donation registries. Responses were analyzed with the Wilcoxon Signed-Rank test, the Kruskal-Wallis test, and the Dunn's test.

Results

The majority of respondents were supportive of FVCA in 10 out of 11 statements (P < 0.0001). They would be willing to undergo FVCA if they suffered from facial disfigurement; believe FVCA is as important as other organ transplants; believe faces should be included on the organ donation registry; support insurance companies providing coverage for FVCA regardless of trauma etiology; support tax dollars funding the procedure; and believe FVCA improves physical appearance and quality of life. Although respondents generally supported their tax dollars funding the procedure, fewer supported this for self-inflicted trauma (P > 0.01).

Conclusions

This study highlights a disconnect between public preference for insurance coverage of FVCA and current lack of coverage in practice. Respondents' acceptance of including faces in organ donation registries may help alleviate the issue of locating a donor, and increasing financial coverage may broaden this procedure's accessibility to a wider range of individuals.

Differential donor management of pediatric vs adult organ donors and potential impact on pediatric lung transplantation

BACKGROUND

Despite clinical progress over time, a shortage of suitable donor organs continues to limit solid organ transplantation around the world. Lungs are the organs most likely to be assessed as unsuitable during donor management among all transplantable organs. Although the number of lung transplants performed in children is limited, death on the wait list remains a barrier to transplant success for many potential transplant candidates. Optimizing organ donor management can yield additional organs for transplant candidates.

METHODOLOGY

We accessed the Donor Management Goal (DMG) Registry to evaluate the efficiency and efficacy of donor management in the procurement of lungs for transplantation. Further, we stratified donors by age and compared pediatric age cohorts to adult cohorts with respect to attainment of donor management target goals and successful pathway to transplantation. We utilized recipient data from the Organ Procurement Transplantation Network (OPTN) to put this data into context. The DMG bundle consists of nine physiologic parameters chosen as end-points guiding donor management for potential organ donors. The number of parameters fulfilled has been regarded as an indication of efficacy of donor management.

RESULTS

We noted a markedly lower number of organ donors in the pediatric age group compared to adults. On the other hand, the number of donors greatly exceeds the number of infants, children and adolescents who undergo lung transplantation. Organs transplanted per donor peaks in the adolescent age group. At initial donor referral, DMG bundle attainment is lower in all age groups and improves during donor management. With respect to oxygenation, there is less overall improvement in younger donors compared to older donors during donor management. When donors who yield lungs for transplantation are compared to those whose lungs were not transplanted, oxygenation improved more substantially during donor management. Furthermore, improved oxygenation correlated with the total number of organs transplanted per donor.

CONCLUSIONS

In the face of continued wait list mortality on the pediatric lung transplant wait list, the number of young donors may not be a limiting factor. We believe that this dataset provides evidence that management of young pediatric donors is not as consistent or efficient as the management of older donors, potentially limiting the number of life-saving organs for pediatric lung transplant candidates. Across all ages, optimizing donor lung management may increase the potential to transplant multiple other organs.

A study on the perception, knowledge, attitude, and practices of eye donation among fresh medical graduates in India

OBJECTIVE

The objective of the study was to assess the perception, knowledge, attitude, and practices of eye donation among fresh medical graduates in India.

MATERIALS AND METHODS

Responses to a semi-structured questionnaire were collected from 410 respondents using an online Google Form which were analyzed using IBM SPSS software version 21.

RESULTS

First information source about eye donation was textbooks (31%), while ophthalmologists accounted for 10.7%. Forty-two respondents had pledged their eyes, 116 were willing to pledge their eyes. Majority had "adequate" knowledge (74.1%). The knowledge levels were directly related to the practice of motivation for eye donation (P = 0.032). Around 62% had "poor" eye donation practices. Significant relationship between practice and knowledge levels (P = 0.004) was noted. Participants who graduated from institutions with eye banks were more likely to have good practice (P = 0.005).

CONCLUSIONS

A curriculum focusing on practical exposure to eye donation and eye banking services would address the current deficits in eye donation. Reinforcing knowledge of eye banking among non-ophthalmologist doctors can enhance the eye donation trend. Timely counseling of patients and bystanders by well-informed sensitized doctors is hence of utmost importance.

Exploring predisposing factors and pathogenesis contributing to injuries of donor lungs

INTRODUCTION

Lung transplantation (LTx) remains the only therapeutic strategy for patients with incurable lung diseases. However, its use has been severely limited by the narrow donor pool and potential concerns of inferior quality of donor lungs, which are more susceptible to external influence than other transplant organs. Multiple insults, including various causes of death and a series of perimortem events, may act together on donor lungs and eventually culminate in primary graft dysfunction (PGD) after transplantation as well as other poor short-term outcomes.

AREAS COVERED

This review focuses on the predisposing factors contributing to injuries to the donor lungs, specifically focusing on the pathogenesis of these injuries and their impact on post-transplant outcomes. Additionally, various maneuvers to mitigate donor lung injuries have been proposed.

EXPERT OPINION

The selection criteria for eligible donors vary and may be poor discriminators of lung injury. Not all transplanted lungs are in ideal condition. With the rapidly increasing waiting list for LTx, the trend of using marginal donors has become more apparent, underscoring the need to gain a deeper understanding of donor lung injuries and discover more donor resources.

Kidney nonprocurement in deceased donors with acute kidney injury

BACKGROUND

Acute kidney injury (AKI) is common in deceased organ donors and is associated with high rates of kidney discard by transplant centers. High discard rates may consequently drive nonprocurement of these kidneys by organ procurement organizations. We aimed to study the relationship between donor AKI and kidney nonprocurement.

METHODS

Using U.S. registry data, we identified donors with at least one organ recovered from 2008 to 2018. We compared characteristics of donors with no kidneys procured across AKI stages, and used multivariable logistic regression to evaluate the relationship between AKI severity and kidney nonprocurement.

RESULTS

Overall 14 543 kidneys from 7620 donors were not procured, among which 93% were from donors with AKI. For 6945 donors with no kidneys procured but an extrarenal organ recovered, most had stage 3 (51%), followed by stage 1 (27%) and stage 2 AKI (15%). Nonprocured stage 3 donors were the youngest and had the lowest Kidney Donor Risk Index of all nonprocured donors. Adjusted odds of kidney nonprocurement were 1.14 (95%CI 1.02-1.27) for stage 1, 1.25 (95%CI 1.12-1.41) for stage 2, and 10.37 (95%CI 9.30-11.56) for stage 3 donors, compared to non-AKI donors. Among donors with minimum creatinine <1.5 mg/dl, stage 2 and 3 AKI were still associated with significantly higher odds of nonprocurement.

CONCLUSIONS

AKI severity is a strong risk factor for kidney nonprocurement. Efforts to address the organ shortage should focus on encouraging procurement and utilization of kidneys from deceased donors with severe AKI, given the large and rising prevalence of donor AKI and excellent transplant outcomes with these kidneys.

Potential organ donors with primary brain tumours: missed opportunities for donation and transplantation identified in Australian cohort study 2010-2015

BACKGROUND

Potential organ donors with primary brain tumours (PBT) frequently donate, however some may be declined due to uncertainty about tumour classification or transmission risk to transplant recipients. We sought to describe transmission risk and donation outcome of potential donors with PBT, including identifying missed opportunities for transplantation, and any PBT transmission events.

METHODS

We undertook a population-based cohort study in NSW of all potential donors 2010-2015. PBT potential donors were characterized according to tumour grade and transmission risk, and whether they donated organs. Data linkage was used to determine agreement of risk assessment of potential donors to that in the Biovigilance Register, and to identify any PBT transmissions.

RESULTS

Of 2957 potential donors, 76 (3%) had PBTs. There was agreement of risk assessment in 44 (58%) cases. PBT potential donors had fewer comorbidities (1.6 vs. 2.1, P = 0.006) than non-PBT potential donors. Forty-eight (63%) potential donors were declined for non-PBT reasons, 18 (24%) were declined because of perceived PBT transmission risk and 10 (13%) donated. All PBT donors had WHO-I or -II tumours, and none had a ventriculo-pertioneal shunt. No transmission events occurred.

CONCLUSION

Donors with WHO-I/II PBT appear to have minimal risk of tumour transmission in solid organ transplantation; it is reassuring that no PBT transmission occurred. There is evidence of risk aversion to referrals with WHO-III/IV tumours. There exists opportunity to improve potential donor risk assessment at the time of referral using integrated data sets, and to increase organ donation and transplantation rates through greater utilization of PBT referrals.

Religious and cultural aspects of organ donation: Narrowing the gap through understanding different religious beliefs

BACKGROUND

The supply of viable organ donations falls significantly below the demand. Discrepancies concerning the availability of transplants cannot be explained solely by the various consent models used in different countries. There is evidence that religious beliefs of patients, potential donors, and healthcare professionals also play an important role in the decision-making process. However, to date, very little research has been conducted on the consequences of specific religious beliefs on transplantation rates. The aim of this review was to outline the religious views of Christians, Muslims, Jews, Hindus, and Buddhists on organ donation. Additionally, different approaches to address this topic throughout the world are presented and can function as a helpful background for medical professionals.

METHODS

The umbrella organizations of the five largest religious movements were asked for written statements concerning the subject of organ transplantation, and a literature review was performed.

RESULTS

All German religious umbrella organizations have a positive view on organ donation, if certain rules are respected. Particularly, deceased donations are supported as a sign of altruism, love, and respect for another human being. Different aspects of the transplant process (e.g., consent, brain death, and respect for the dead body) are particularly stressed in some religions.

CONCLUSIONS

In general, the religious groups addressed here are in favor of organ donations. Nevertheless, there are important particularities to be considered. Hopefully, understanding the different religious views on organ donations will help in reducing religious concerns about transplantation and narrowing the gap between the need and the availability of organ donations.

Kidney utilization in the Netherlands - do we optimally use our donor organs?

BACKGROUND

To ensure optimal utilization of deceased donor kidneys, it is important to understand the precise reasons why kidneys are discarded. In this study we aimed to obtain a comprehensive overview of kidney utilization and discard during the entire donation process in the Netherlands.

METHODS

In this retrospective cohort study we analysed kidney utilization of 3856 kidneys in the Netherlands between 1 January 2015 and 31 December 2020. For every kidney that was not transplanted, we determined the moment of and reason for discard through a unique case-by-case assessment.

RESULTS

Kidney discard according to the traditional definition (procured but not transplanted) was 7.8%. However, when kidneys that seemed medically suitable at the beginning of the donation process were also included, many more potential donor kidneys were lost and the total non-utilization was 24.4%. Subjectively presumed impaired organ quality was responsible for 34.2% of all discarded kidneys. Two-thirds of kidneys discarded due to acute kidney injury (AKI) had only AKI stage 1 or 2.

CONCLUSION

The classical definition of organ discard underestimates the non-utilization of deceased donor kidneys. Strategies to improve kidney utilization could be a revision of the maximum allowed agonal time in donation after circulatory death, careful consideration in reporting and accepting kidneys from donors with AKI and a prospectively filled registry of detailed organ discard reasons, including the 'silent' non-utilization before procurement.

A Qualitative Content Analysis of Comments on Press Articles on Deemed Consent for Organ Donation in Canada

BACKGROUND AND OBJECTIVES

In 2019, two Canadian provinces became the first jurisdictions in North America to pass deemed consent legislation to increase deceased organ donation and transplantation rates. We sought to explore the perspectives of the deemed consent legislation for organ donation in Canada from the viewpoint of individuals commenting on press articles.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

In this qualitative descriptive study, we extracted public comments regarding deemed consent from online articles published by four major Canadian news outlets between January 2019 and July 2020. A total of 4357 comments were extracted from 35 eligible news articles. Comments were independently analyzed by two research team members using a conventional content analysis approach.

RESULTS

Commenters' perceptions of the deemed consent legislation for organ donation in Canada predominantly fit within three organizational groups: perceived positive implications of the bills, perceived negative implications of the bills, and key considerations. Three themes emerged within each group that summarized perspectives of the proposed legislation. Themes regarding the perceived positive implications of the bills included majority rules, societal effect, and prioritizing donation. Themes regarding the perceived negative implications of the bills were a right to choose, the potential for abuse and errors, and a possible slippery slope. Improving government transparency and communication, clarifying questions and addressing concerns, and providing evidence for the bills were identified as key considerations.

CONCLUSIONS

If deemed consent legislation is meant to increase organ donation and transplantation, addressing public concerns will be important to ensure successful implementation.

Disseminated tuberculosis in a lung transplant recipient presenting as tenosynovitis, subcutaneous nodules, and liver abscesses

Tuberculosis is of particular concern in lung transplant recipients. We present the case of a patient who received a double lung transplant from a deceased donor from Mexico and developed disseminated tuberculosis 60 days post-transplant manifested as tenosynovitis, liver abscesses, and subcutaneous nodules with no definitive lung allograft involvement. The recipient did not have evidence of tuberculosis on explanted lungs, had a negative interferon gamma release assay pre-transplant, and did not have risk factors for this infection. Mycobacterium tuberculosis should remain in the differential diagnosis of early post-transplant infections with atypical presentations, evidence of dissemination, or lack of improvement with appropriate antimicrobial coverage, even in the absence of typical lung findings.

Media use and organ donation willingness: A latent profile analysis from Chinese residents

Background

Previous studies have paid attention to media as an important channel for understanding organ donation knowledge and have not divided groups according to the degree of media use to study their differences in organ donation. Therefore, the purpose of this study is to explore the influence of media use on organ donation willingness and the influencing factors of organ donation willingness of people with different media use levels.

Methods

A cross-sectional study of residents from 120 cities in China was conducted by questionnaire survey. Using Mplus 8.3 software, the latent profile analysis of seven media usage related items was made, and multiple linear regression was performed to analyze the influence of varying levels of media use on organ donation willingness of different population.

Results

All the interviewees were divided into three groups, namely, "Occluded media use" (9.7%), "Ordinary media use" (67.1%) and "High-frequency media use" (23.2%). Compared with ordinary media use, high-frequency media population (β = 0.06, P < 0.001) were positively correlated with their willingness to accept organ donation, residents who used media occlusion (β = -0.02, P < 0.001) were negatively correlated with their willingness to accept organ donation. The influencing factors of residents' accept willingness to organ donation were different among the types of occluded media use, ordinary media use and high-frequency media use.

Conclusion

It is necessary to formulate personalized and targeted dissemination strategies of organ donation health information for different media users.

A cross-sectional study to assess concerns and commitment for organ donation among students of arts, science and commerce streams in degree colleges in a metropolitan city

Background

Organ donation has been one of the greatest advances of modern science that has resulted in many patients getting a renewed lease of life. Organs can be donated by a living person, after natural death, and many more organs can be donated after brain stem death (BSD) as "cadaver transplant" or "deceased donor transplant". It is believed that youths are the leading decision-makers in families. So identifying their concerns regarding organ donation, creating awareness in them and changing their beliefs may increase the number of consents for organ donation in the long run.

Materials and Methods

A prospective interventional study was done among 206 students of nine degree colleges (arts, science and commerce streams) using random sampling during the study duration of 18 months.

Results

One hundred two (48.57%) participants were willing to donate their organs after their BSD, while after the session in post test, the number increased significantly to 163 (77.61%). And when this increase was compared within streams, it was found that there was no significant difference in knowledge of students of arts, science and commerce streams. (P > 0.05).

Conclusions

Willingness to donate their own organs or that of the relative's in case of brain stem death had increased significantly after session in the post test. And there was no significant difference found in the increase in knowledge when compared with all the three streams, religion, and gender, which indicates that the level of increase in knowledge amongst arts and commerce students is comparable to that of science students.

Transplanting thoracic COVID-19 positive donors: An institutional protocol and report of the first 14 cases

We present our institution's protocol for evaluating and transplanting thoracic organs from COVID-19 positive donors and report the outcomes to date. Hearts from donors testing positive for COVID-19 on any test were eligible for transplantation at our institution provided the donor exhibited no evidence of hypercoagulability or COVID-19 induced hyperinflammatory state during terminal hospitalization. Lungs were eligible if the donor first tested PCR positive on nasopharyngeal swab (NPS) for COVID-19 > 20 days prior to procurement and had a negative lower respiratory tract specimen. We performed 14 thoracic transplants in 13 recipients using organs from COVID-19 positive donors. None of the recipients or healthcare members acquired COVID-19. No recipients suffered unexpected acute rejection. Patient survival is 92% to date, with graft survival 93%. The use of hearts from COVID-19 positive donors may be safe and effective. Transplantation of lungs is unresolved but may be cautiously pursued under the restricted circumstances.

Barrett's Power Theory: Re-Conceptualizing the Pediatric Organ Donation Experience With Letter Writing

Pediatric organ donation is often a time of reported turbulence and isolation for both families involved. Communication through letter writing is a way for those families to connect and heal, if they choose to participate. Barrett's Power as Knowing in Participation in Change Theory, with its accompanying health patterning, is applicable to this experience by facilitating awareness, choices, freedom to act intentionally, and involvement in the change process related to the pediatric organ donation process. Two families' experiences connected through organ donation and letter writing, as conceptualized through the lens of Barrett's Power Theory, supported future use of patterning of knowing participation in change for families.

Excavating the social representations and perceived barriers of organ donation in China over the past decade: A hybrid text analysis approach

Background

Organ donation has been claimed as a prosocial behavior to prolong the recipient's life and deliver great love. However, the supply-demand ratio of organs in China is highly unbalanced. Being entangled with multiple factors derived from individual and supra-individual levels, organ donation in China is important but sensitive. Previous scholars usually depended on obtrusive approaches to explore the facilitators and hindrances of organ donation, which is hard to discover genuine perceptions toward organ donation. Besides, relatively limited scholarly attention has been paid to what hampers organ donation in China.

Objective

We intended to excavate the diversified social representations and perceived barriers to organ donation in China over the past decade.

Method

Two kinds of text analysis methods-semantic network analysis and conventional content analysis, were applied to 120,172 posts from ordinary users on the Sina Weibo platform to address the research questions.

Results

Regarding social representations, the "hope, understanding, and acceptance" of organ donation was the most pronounced one (34% of the whole semantic network), followed by "family story" (26%), "the procedure of organ donation in NGOs" (15%), "the practical value of organ donation" (14%), and "organ donation in the medical context" (11%). Regarding perceived barriers, a four-layer framework was constructed, including (1) the individual level, mainly about the fear of death and postmortem autopsy; (2) the familial level, which refers to the opposition from family members; (3) the societal level, which alludes to distrust toward medical institutions and the general society; (4) the cultural level, which covers religious-cultural concerns about fatalism.

Conclusion

In concordance with prior works on social representations regarding organ donation, the current study also uncovered the coexistence of antithetical representations about organ donation-the longing for survival and the fear of death. This representation pair serves as the foundation of Chinese people's ambivalence. Besides, family-related narratives were dispersed over various representations, demonstrating the critical position of family support in organ donation. Moreover, the four-layer framework concerning donation barriers affords a reference for future empirical studies. The practical implications of this work are further discussed.
