The Impact of Religion and Provision of Information on Increasing Knowledge and Changing Attitudes to Organ Donation: An Intervention Study

One of the most significant developments in recent history has probably been organ donation and organ transplantation. They are frequently the only treatment available in certain cases. However, there is an ever-increasing discrepancy between the number of people needing transplantation and the organs available, because the decision to donate an organ is up to each individual. The study aims to assess the impact of the intervention on knowledge, attitudes and practices on organ donation among religious immigrants in Sweden. Data were collected through three group interviews using open-ended questions and qualitative content analysis. Thirty-six participants, 18 males and 18 females from six countries, participated in the focus group interviews. The analysis of the collected data resulted in two main categories: "Religion in theory and practice" and "More information-more knowledge about organ donation" including seven subcategories. Understanding of religion and religiosity, happiness by taking the class, the practice of religion in everyday life, the overcoming the prejudices in religion, having more information about organ donation and the donations process, as well as that the increased information changes people's minds, were some of things the informants emphasised as predictors of the decision of organ donation. A class dealing with religion, the religious aspects of organ donation and the way the Swedish healthcare system is organised increased people's knowledge and changed their attitudes so they became potential organ donors. More intervention studies are needed in every field of medicine to build confidence and give time to educate and discuss issues with potential organ donors in Sweden.

Deceased Organ Donation in Syria: Challenges and Solutions

The first living-donor kidney transplant in Syria was performed 41 years ago; by 2019, 5407 renal transplants had been performed there. Three heart transplants from deceased donors were performed in the late 1980s; cardiac transplant activities have since discontinued. In 2003, a new, national Syrian legislation was enacted authorizing the use of organs from living unrelated donors and from deceased donors. This important law was preceded by another big stride in this regard: the acceptance by the higher Islamic religious authorities in Syria in 2001 of the principle of procurement of organs from deceased donors, provided that consent is given by a first- or second-degree relative. After the enactment of this law, kidney transplant rates increased from 7 per million population in 2002 to 17 per million population in 2007. Kidney transplants performed abroad for Syrian patients declined from 25% in 2002 to < 2% in 2007. Kidney transplants continued at comparable rates until 2010, before the beginning of the political crisis in 2011. Four decades after the first successful kidney transplant in Syria, however, patients needing an organ transplant must rely on living donors only. Moreover, 17 years after the law authorizing use of organs from deceased donors, a program is still not in place in Syria, and additional improvement of the legal framework is needed. The war, limited resources, and lack of public awareness about the importance of organ donation and transplant appear to be major factors inhibiting initiation of a deceased-donor program in Syria. A concerted and ongoing education campaign is needed to increase awareness of organ donation, change negative public attitudes, and gain societal acceptance. Every effort must be made to initiate a deceased-donor program to lessen the burden on living donors and to enable national self-sufficiency in organs for transplant.

Recent Decrease in Organ Donation from Brain-Dead Potential Organ Donors in Korea and Possible Causes

BACKGROUND

In 1999, the Organ Transplantation Act legalized organ donation from brain-dead patients. As a result of the government's continued efforts, the number of brain-dead donors steadily increased from 2002 through 2016. However, the number has declined since 2017. This paper examined the possible reasons behind the decline in brain-dead organ donation.

METHODS

This investigation was an analysis of published data from the Korea Organ Donation Agency annual reports from 2013 to 2018.

RESULTS

The number of brain-dead organ donors in Korea rose steadily until 2016, declined in 2017 for the first time since 2002, and then dropped sharply in 2018. Although the number of brain-dead potential organ donors increased between 2017 and 2018, the number of eligible donors decreased, suggesting that patient families rejected the brain-death determination process and brain-dead organ donation. Statistics gathered during identification of brain-dead potential donors and actual donations confirm that rejection or withdrawal of consent by the family has increased. During the same period when donation from brain- dead patients decreased, five events occurred: 1) compensation for donor families was abolished; 2) an incident of mistreatment of a brain-dead donor's remains occurred; 3) the Life-Sustaining Treatment Act was enacted, providing a legal procedure whereby families of brain-dead patients could forgo life-sustaining treatment; 4) residents' work week was limited to 80 hours; and 5) the Labor Standards Law was amended.

CONCLUSION

Fewer eligible donors in spite of an increase in brain-dead potential organ donors suggests that reduction in these donations resulted mainly from factors associated with family consent. Among such factors, implementation of the Life-sustaining Treatment Act appears to be most important. Abolition of family compensation and the incident in which a brain-dead donor's remains were mistreated may also have influenced family consent.

Knowledge, attitude and willingness of different ethnicities to participate in cadaver donation programs

Knowledge, attitude and willingness of ethnic minorities in China towards cadaver donation programs were assessed. Questionnaire and interviews were conducted to investigate Yi, Bai, Hani, Dai and Han ethnicities. Educational level and per capita income of ethnic minorities were lesser than those of Han ethnicity (p<0.01). Agriculture was the primary occupation and proportions of technical personnel and public officials was lesser among ethnic minorities (p<0.01). Surveyed ethnic minorities universally practice religious traditions, Bai and Dai ethnicities practice Buddhist beliefs also (p<0.01). Knowledge of Yi, Bai, Hani and Dai ethnic respondents was lesser than those of Han ethnicity (p<0.01). Over 83.8% of Yi, Bai, Hani and Dai ethnicity residents were unwilling to register for body donation programs with receiving a driver's license (p<0.01). Less than 46.9% of ethnic minorities supported use of honorary certificates (p<0.01). Ethnic minorities were supportive of financial compensation for body donations and denied that financial compensation led to the commercialization of cadaver donation (p<0.01, p<0.01). Willingness of ethnic minorities to participate in cadaver donation programs was primarily related to religious beliefs (p<0.01), economic status (p<0.01). Knowledge, attitude and willingness of ethnic minorities to participate in cadaver donation programs were markedly different from those of Han ethnicity, and the religious belief and economic status played a decisive role. To increase participation, programs based on respecting religious belief should be developed to support improvements in economy, education, medical care and social security system.

Expanding pancreas donor pool by evaluation of unallocated organs after brain death: Study protocol clinical trial (SPIRIT Compliant)

BACKGROUND

Pancreas graft quality directly affects morbidity and mortality rates after pancreas transplantation (PTx). The criteria for pancreas graft allocation are restricted, which has decreased the number of available organs. Suitable pancreatic allografts are selected based on donor demographics, medical history, and the transplant surgeon's assessment of organ quality during procurement. Quality is assessed based on macroscopic appearance, which is biased by individual experience and personal skills. Therefore, we aim to assess the histopathological quality of unallocated pancreas organs to determine how many unallocated organs are potentially of suitable quality for PTx.

METHODS AND ANALYSIS

This is a multicenter cross-sectional explorative study. The demographic data and medical history of donor and cause of rejection of the allocation of graft will be recorded. Organs of included donors will be explanted and macroscopic features such as weight, color, size, and stiffness will be recorded by 2 independent transplant surgeons. A tissue sample of the organ will be fixed for further microscopic assessments. Histopathologic assessments will be performed as soon as a biopsy can be obtained. We will evaluate up to 100 pancreata in this study.

RESULT

This study will evaluate the histopathological quality of unallocated pancreas organs from brain-dead donors to determine how many of these unallocated organs were potentially suitable for transplantation based on a histopathologic evaluation of organ quality.

CONCLUSION

The comprehensive findings of this study could help to increase the pancreas graft pool, overcome organ shortage, reduce the waiting time, and also increase the number of PTx in the future. Registration number: ClinicalTrials.gov: NCT04127266.

The effect of the National Kidney Registry on the kidney-exchange market

We assess the causal effect of the National Kidney Registry (NKR), the largest national kidney-exchange network in the U.S., on kidney-exchange outcomes. Analyzing a unique database hosted by the Scientific Registry of Transplant Recipients (SRTR) that contains information on all kidney donors, wait-listed candidates, and transplant recipients in the U.S., we find that patients in an NKR hospital are 2.5-3 times more likely than their counterparts in a non-NKR hospital to receive a transplant from a living donor, conditional on wait-time. At the same time, NKR participation does not have a significant effect on the desirability of donors and the health status of recipients. We employ various approaches to ensure our finding is robust in addressing the non-random sorting of patients and donors. As far as the outcomes we study, the expansion of the NKR brings about an overall positive impact on the kidney exchange market.

Geographic Differences in Population Health and Expected Organ Supply in the Gulf Coast Region of the United States Compared to Non-Gulf States

BACKGROUND

The Final Rule aimed to reduce geographic disparities in access to transplantation by prioritizing the need for transplant over donor proximity. However, disparities in waiting times persist for deceased donor kidney transplantation. The kidney allocation system implemented in 2014 does not account for potential local supply based on population health characteristics within a donation service area (DSA). We hypothesized that regions with traditionally high rates of comorbid disease, such as the states located along the Gulf of Mexico (Gulf States), may be disadvantaged by limited local supply secondary to poor population health.

METHODS

Using data from the Robert Wood Johnson Foundation County Health Rankings, the United States Renal Data System, and the Scientific Registry of Transplant Recipients, we compared population-level characteristics and expected kidney donation rates by Gulf States location.

RESULTS

Prevalence of African American ethnicity, end-stage renal disease, diabetes, fair/poor self-rated health, physical inactivity, food insecurity, and uninsurance were higher among Gulf State DSAs. On unadjusted analyses, Gulf State DSAs were associated with 3.52 fewer expected kidney donors per 100 eligible deaths than non-Gulf States. After adjustment, there was no longer a statistically significant difference in expected kidney donation rate.

CONCLUSIONS

Although Gulf State DSAs have lower expected donation rates, these differences appear to be driven by the prevalence of health factors negatively associated with donation rate. These data suggest the need to discuss population health characteristics when examining kidney allocation policy, to account for potential lower supply of donors and to further address geographic disparities in access to kidney transplantation.

How Did the War Affect Organ Transplantation in Syria?

Since 2011, the Syrian conflict has destroyed much of the country's infrastructure. The deteriorating humanitarian situation has involved health workers and facilities. In 2010, before the war, 385 kidney transplants were performed in Syria. This number declined to 154 in 2013 (60% less) before increasing to 251 transplants in 2018, which is still 35% less than the number of transplants performed before the war. In addition, the number of operational kidney transplant centers has decreased from 8 in 2010, distributed over 3 cities, to only 4 in 2013, all located in Damascus, which increased to 6 centers in 2019. Interestingly, with regard to type of living donor, the percentage of unrelated kidney donors has decreased by 20% for unclear reasons. Another alarming statistic is that more than 50% of kidney transplant physicians and surgeons are no longer practicing transplant medicine in their centers, either because they have left the country or because their centers had become nonoperational. Since the war, free and timely provision of immunosuppressive drugs for all patients in all provinces has been a leading challenge for health authorities and transplant patients. This difficulty has led to adverse medical consequences for patients. A project to initiate liver transplant came to a halt because of complex reasons but mainly because foreign trainers could not visit Syria. Although the autologous bone marrow transplant program had slowed until recently, it has become more active, involving both autologous and allogeneic transplants. The deceased-donor program is still not available in Syria; the war has just reinforced the many reasons that prevented the start of this program before the conflict. The commitment of transplant teams despite these large challenges continues to be extraordinary. The Syrian conflict has affected all aspects of organ transplant, paralyzing new projects and negatively affecting existing programs.

Analysis of the Trend Over Time of High-Urgency Liver Transplantation Requests in Italy in the 4-Year Period 2014-2017

BACKGROUND

The national protocol for the handling of high-urgency (HU) liver organ procurement for transplant is administered by the Italian National Transplant Center. In recent years, we have witnessed a change in requests to access the program. We have therefore evaluated their temporal trend, the need to change the access criteria, the percentage of transplants performed, the time of request satisfaction, and the follow-up.

METHODS

We analyzed all the liver requests for the HU program received during the 4-year period of 2014 to 2017 for adult recipients (≥18 years of age): all the variables linked to the recipient or to the donor and the organ transplants are registered in the Informative Transplant System as established by the law 91/99. In addition, intention to treat (ITT) survival rates were compared among 4 different groups: (1) patients on standard waiting lists vs (2) patients on urgency waiting lists, and (3) patients with a history of transplant in urgency vs (4) patients with a history of transplant not in urgency.

RESULTS

Out of the 370 requests included in the study, 291 (78.7%) were satisfied with liver transplantation. Seventy-nine requests (21.3%) have not been processed, but if we consider only the real failures, this percentage falls to 13.1% and the percentage of satisfied requests rises to 86.9%. The average waiting period for liver transplantation (LT) is 1.7 days and most requests (74%) are met in less than 24 hours, if we consider the hours between the registration of the request and the donor reporting . The percentage of late retransplantations is 2.1%. The clinical indication for HU-LT that appears to improve over time is hepatic artery thrombosis (82.5%). The overall 1-year patient survival is 68.3%. The overall 1-year graft survival, performed on all the patients, is 89% and all the indications for HU-LT appear to go well over time with an average survival rate greater than 85%.

CONCLUSIONS

The indications for HU-LT are changing according to the changes in the hepatologic field in recent years. The centralized management of requests has proven to be successful in optimizing responses. Urgent LT is confirmed to be lifesaving in its timeliness.

Evaluation of Risk Factors for Heart-Lung Transplant Recipient Outcome: An Analysis of the United Network for Organ Sharing Database

BACKGROUND

Heart-lung transplantation (HLTx) is an effective treatment for patients with advanced cardiopulmonary failure. However, no large multicenter study has focused on the relationship between donor and recipient risk factors and post-HLTx outcomes. Thus, we investigated this issue using data from the United Network for Organ Sharing database.

METHODS

All adult patients (age ≥18 years) registered in the United Network for Organ Sharing database who underwent HLTx between 1987 and 2017 were included (n=997). We stratified the cohort by patients who were alive without retransplant at 1 year (n=664) and patients who died or underwent retransplant within 1 year of HLTx (n=333). The primary outcome was the influence of donor and recipient characteristics on 1-year post-HLTx recipient death or retransplant. Kaplan-Meier curves were created to assess overall freedom from death or retransplant. To obtain a better effect estimation on hazard and survival time, the parametric Accelerated Failure Time model was chosen to perform time-to-event modeling analyses.

RESULTS

Overall graft survival at 1-year post-HLTx was 66.6%. Of donors, 53% were male, and the mean age was 28.2 years. Univariable analysis showed advanced donor age, recipient male sex, recipient creatinine, recipient history of prior cardiac or lung surgery, recipient extracorporeal membrane oxygenation support, transplant year, and transplant center volume were associated with 1-year post-HLTx death or retransplant. On multivariable analysis, advanced donor age (hazard ratio [HR], 1.017; P=0.0007), recipient male sex (HR, 1.701; P=0.0002), recipient extracorporeal membrane oxygenation support (HR, 4.854; P<0.0001), transplant year (HR, 0.962; P<0.0001), and transplantation at low-volume (HR, 1.694) and medium-volume centers (HR, 1.455) in comparison with high-volume centers (P=0.0007) remained as significant predictors of death or retransplant. These predictors were incorporated into an equation capable of estimating the preliminary probability of graft survival at 1-year post-HLTx on the basis of preoperative factors alone.

CONCLUSIONS

HLTx outcomes may be improved by considering the strong influence of donor age, recipient sex, recipient hemodynamic status, and transplant center volume. Marginal donors and recipients without significant factors contributing to poor post-HLTx outcomes may still be considered for transplantation, potentially with less impact on the risk of early postoperative death or retransplant.

Monthly variance in UK renal transplantation activity: a national retrospective cohort study

OBJECTIVE

To identify whether renal transplant activity varies in a reproducible manner across the year.

DESIGN

Retrospective cohort study using NHS Blood and Transplant data.

SETTING

All renal transplant centres in the UK.

PARTICIPANTS

A total of 24 270 patients who underwent renal transplantation between 2005 and 2014.

PRIMARY OUTCOME

Monthly transplant activity was analysed to see if transplant activity showed variation during the year.

SECONDARY OUTCOME

The number of organs rejected due to healthcare capacity was analysed to see if this affected transplantation rates.

RESULTS

Analysis of national transplant data revealed a reproducible yearly variance in transplant activity. This activity increased in late autumn and early winter (p=0.05) and could be attributed to increased rates of living (October and November) and deceased organ donation (November and December). An increase in deceased donation was attributed to a rise in donors following cerebrovascular accidents and hypoxic brain injury. Other causes of death (infections and road traffic accidents) were more seasonal in nature peaking in the winter or summer, respectively. Only 1.4% of transplants to intended recipients were redirected due to a lack of healthcare capacity, suggesting that capacity pressures in the National Health Service did not significantly affect transplant activity.

CONCLUSION

UK renal transplant activity peaks in late autumn/winter in contrast to other countries. Currently, healthcare capacity, though under strain, does not affect transplant activity; however, this may change if transplantation activity increases in line with national strategies as the spike in transplant activity coincides with peak activity in the national healthcare system.

The changing landscape of live kidney donation in the United States from 2005 to 2017

The number of live kidney donors has declined since 2005. This decline parallels the evolving knowledge of risk for biologically related, black, and younger donors. To responsibly promote donation, we sought to identify declining low-risk donor subgroups that might serve as targets for future interventions. We analyzed a national registry of 77 427 donors and quantified the change in number of donors per 5-year increment from 2005 to 2017 using Poisson regression stratified by donor-recipient relationship and race/ethnicity. Among related donors aged <35, 35 to 49, and ≥50 years, white donors declined by 21%, 29%, and 3%; black donors declined by 30%, 31%, and 12%; Hispanic donors aged <35 and 35 to 49 years declined by 18% and 15%, and those aged ≥50 increased by 10%. Conversely, among unrelated donors aged <35, 35 to 49, and ≥50 years, white donors increased by 12%, 4%, and 24%; black donors aged <35 and 35 to 49 years did not change but those aged ≥50 years increased by 34%; Hispanic donors increased by 16%, 21%, and 46%. Unlike unrelated donors, related donors were less likely to donate in recent years across race/ethnicity. Although this decline might be understandable for related younger donors, it is less understandable for lower-risk related older donors (≥50 years). Biologically related older individuals are potential targets for interventions to promote donation.

Profile and Motivations of Registered Whole-Body Donors in Turkey: Istanbul University Experience

Little is known regarding the profiles of whole body donors in Muslim majority countries where donation is scarce. Therefore, this study aims to profile registered donors in Turkey by means of a survey. The explored data could be used to improve ongoing campaign efforts and ethical practices such as commemoration services. Registered donors of the donation programs at the two faculties of medicine of Istanbul University were compared with the national population and a cluster analysis was performed to reveal any concealed sub-groups. Data from 188 respondents were analyzed. The majority of registered donors were married (42%), male (65.4%), aged over 50 years (76%), held a tertiary education degree (49.7%), and were irreligious (58.5%). Cluster analysis revealed two groups with significantly different educational levels, marital statuses, and religious choices. Regarding whether their bodies could be used for education or research, the majority (64.5%) of the respondents left the decision to the anatomy department. Similarly, 73.8% approved indefinite use of their organs, body parts and/or skeletons. The respondents were also willing to share their medical history (94.2%) and personal information (81.6%) if needed. Motivational themes for body donation including usefulness, impermanence, religion, awareness, and kinship were devised after a thematic analysis. Among the respondents, 56.5% were registered organ donors and 63.3% were frequent blood donors. The results of this study provide data that may help revising informed consent forms, developing and implementing thanksgiving ceremonies, and selecting additional targets for supporting body donation campaign activities such as organ and blood donation units.

Impact of Melatonin in Solid Organ Transplantation-Is It Time for Clinical Trials? A Comprehensive Review

Solid organ transplantation is the "gold standard" for patients with end-stage organ disease. However, the supply of donor organs is critical, with an increased organ shortage over the last few years resulting in a significant mortality of patients on waiting lists. New strategies to overcome the shortage of organs are urgently needed. Some experimental studies focus on melatonin to improve the donor pool and to protect the graft; however, current research has not reached the clinical level. Therefore, this review provides a comprehensive overview of the data available, indicating that clinical evaluation is warranted.

What do people agree to when stating willingness to donate? On the medical interventions enabling organ donation after death

Purpose of the study

The purpose of this study is to explore donor relatives’ experiences of the medical interventions enabling organ donation, as well as to examine the donor relatives’ attitudes towards donating their own organs, and whether or not their experiences have influenced their own inclination to donate.

Methods

The experiences of donor relatives were explored via in-depth interviews. The interviews covered every step from the deceased family member being struck by a severe bleeding in the brain till after the organ recovery, including the medical interventions enabling organ donation. The interviews were analysed through qualitative and quantitative content analysis.

Results

Brain death and organ donation proved to be hard to understand for many donor relatives. The prolonged interventions provided after death in order to enable organ donation misled some relatives to believe that their family member still was alive. In general, the understanding for what treatment aimed at saving the family member and what interventions aimed at maintaining organ viability was low. However, most donor relatives were either inspired to, or reinforced in their willingness to, donate their own organs after having experienced the loss of a family member who donated organs.

Conclusions

There is a need for greater transparency regarding the whole chain of events during the donation process. Yet, having experienced the donation process closely did not discourage the donor relatives from donating their own organs–but rather inspired a willingness to donate. This indicates an acceptance of the medical procedures necessary in order to enable organ donation after death.

Racial/ethnic disparities in waitlisting for deceased donor kidney transplantation 1 year after implementation of the new national kidney allocation system

The impact of a new national kidney allocation system (KAS) on access to the national deceased-donor waiting list (waitlisting) and racial/ethnic disparities in waitlisting among US end-stage renal disease (ESRD) patients is unknown. We examined waitlisting pre- and post-KAS among incident (N = 1 253 100) and prevalent (N = 1 556 954) ESRD patients from the United States Renal Data System database (2005-2015) using multivariable time-dependent Cox and interrupted time-series models. The adjusted waitlisting rate among incident patients was 9% lower post-KAS (hazard ratio [HR]: 0.91; 95% confidence interval [CI], 0.90-0.93), although preemptive waitlisting increased from 30.2% to 35.1% (P < .0001). The waitlisting decrease is largely due to a decline in inactively waitlisted patients. Pre-KAS, blacks had a 19% lower waitlisting rate vs whites (HR: 0.81; 95% CI, 0.80-0.82); following KAS, disparity declined to 12% (HR: 0.88; 95% CI, 0.85-0.90). In adjusted time-series analyses of prevalent patients, waitlisting rates declined by 3.45/10 000 per month post-KAS (P < .001), resulting in ≈146 fewer waitlisting events/month. Shorter dialysis vintage was associated with greater decreases in waitlisting post-KAS (P < .001). Racial disparity reduction was due in part to a steeper decline in inactive waitlisting among minorities and a greater proportion of actively waitlisted minority patients. Waitlisting and racial disparity in waitlisting declined post-KAS; however, disparity remains.

The Onus for Altruism in Kidney Transplantation

Ideally, all programs performing living donor kidney transplantation should educate patients on all contemporary exchange options. They should be strongly encouraged to participate in multicenter exchange, or at least refer those with a willing yet incompatible donor to a center that does, and to preferentially allocate altruistic donor kidneys towards chain initiation.

Emergence of an Israel faith-based community organization facilitating live donor kidney transplantation

BACKGROUND

The 2014 Consensus Conference on Best Practices in Living Kidney Donations recognized live donor kidney transplantation as the best treatment for late-stage kidney disease, yielding superior graft and patient survival, improved quality of life, fewer requirements for dialysis and increased cost-effectiveness compared to deceased donor kidney transplantation. Yet in spite of the excellent results of living kidney donation, the annual number of living kidney donors is declining in many countries, including the United States. In Israel, a non-profit organization, Matnat Chaim ("Gift of Life" in Hebrew), a faith-based initiative, has emerged as a major force for arranging living donor kidney transplantation mainly by facilitating altruistic living unrelated donor transplantation.

METHODS

A retrospective review of the records of live kidney donations facilitated by the Matnat Chaim organization and referred to Israel transplant centers, since the organization's inception in 2009, was performed and compared to published data from the Israel Ministry of Health.

RESULTS

Matnat Chaim has facilitated 494 live kidney donations since its founding in February 2009 until the end of 2017. Of the 124 live kidney transplants performed in 2016, 111 (90%) were shown to be altruistic and unrelated. This large number of donations was associated with a doubling of the total number of kidney transplantations, performed in Israel (data published by the Israel Ministry of Health).

CONCLUSIONS

The success of an Israel community organization in the promotion of kidney transplantation may serve as a model for other religious and non-religious communities worldwide.

The use of human tissue in safety assessment

INTRODUCTION

The safety-related failure of drugs during clinical phases of development is a significant contributor to drug attrition, wasting resources and preventing treatments from reaching patients. A lack of concordance between results from animal models and adverse events in the clinic has been identified as one potential cause of attrition. In vitro models using human tissue or cells have the potential to replace some animal models and improve predictivity to humans.

METHODS

To gauge the current use of human tissue models in safety pharmacology and the barriers to greater uptake, an electronic survey of the international safety assessment community was carried out and a Safety Pharmacology Society European Regional Meeting was organised entitled 'The Use of Human Tissue in Safety Assessment'.

RESULTS

A greater range of human tissue models is in use in safety assessment now than four years ago, although data is still not routinely included in regulatory submissions. The barriers to increased uptake of the models have not changed over that time, with inadequate supply and characterisation of tissue being the most cited blocks.

DISCUSSION

Supporting biobanking, the development of new human tissue modelling technology, and raising awareness in the scientific and regulatory communities are key ways in which the barriers to greater uptake of human tissue models can be overcome. The development of infrastructure and legislation in the UK to support the use of post-mortem or surgical discard tissue will allow scientists to locally source tissue for research.
