Presumed consent in organ donation: the devil is in the detail

This article follows the recent publication of the Organs for Donation Task Force report, "Organs for Transplants", and considers the debate surrounding a change in the law in favour of presumed consent in organ donation.

Role of patient factors, preferences, and distrust in health care and access to liver transplantation and organ donation.

Despite major improvements in access to liver transplantation (LT), disparities remain. Little is known about how distrust in medical care, patient preferences, and the origins shaping those preferences contribute to differences surrounding access. We performed a single-center, cross-sectional survey of adults with end-stage liver disease and compared responses between LT listed and nonlisted patients as well as by race. Questionnaires were administered to 109 patients (72 nonlisted; 37 listed) to assess demographics, health care system distrust (HCSD), religiosity, and factors influencing LT and organ donation (OD). We found that neither HCSD nor religiosity explained differences in access to LT in our population. Listed patients attained higher education levels and were more likely to be insured privately. This was also the case for white versus black patients. All patients reported wanting LT if recommended. However, nonlisted patients were significantly less likely to have discussed LT with their physician or to be referred to a transplant center. They were also much less likely to understand the process of LT. Fewer blacks were referred (44.4% versus 69.7%; P = 0.03) or went to the transplant center if referred (44.4% versus 71.1%; P = 0.02). Fewer black patients felt that minorities had as equal access to LT as whites (29.6% versus 57.3%; P < 0.001). For OD, there were more significant differences in preferences by race than listing status. More whites indicated OD status on their driver's license, and more blacks were likely to become an organ donor if approached by someone of the same cultural or ethnic background (P < 0.01). In conclusion, our analysis demonstrates persistent barriers to LT and OD. With improved patient and provider education and communication, many of these disparities could be successfully overcome.

Attitudes and Knowledge Concerning Corneal Donation in a Population-Based Sample of Urban Chinese Adults.

PURPOSE: To better understand knowledge and attitudes concerning corneal donation among Chinese adults.
METHODS: Randomly selected residents in predetermined age strata 20 to 60+ years completed home-based questionnaires in each of 12 randomly chosen communities in Guangzhou, southern China.
RESULTS: Among 1217 selected persons, 430 (35.3%) completed the questionnaires (mean age 40.4 yrs, 57.9% female). Refusers were older (44.8 yrs, P < 0.001), but sex did not differ (52.2% female, P = 0.07). Among participants, 175 (40.7%) were willing to donate their corneas (WTD). Differences between WTD and not WTD included donation knowledge score (range, 1-12) [WTD (SD) 6.91 ± 2.21, not WTD 5.62 ± 2.43, P < 0.001]; having discussed donation (WTD 26.3%, not WTD 8.63%, P < 0.001); viewing donation as unpopular (WTD 88.0%, not WTD 96.5%, P = 0.001); and feeling donation "damages the body" (WTD 15.4%, not WTD 25.7%, P = 0.013). Associated significantly with WTD in multiple regression models were higher knowledge score [odds ratio (OR) = 1.18, 95% confidence interval (CI), 1.04-1.32, P = 0.008]; not feeling donation "damages the body" (OR = 1.91, 95% CI, 1.07-3.43, P = 0.030); and willingness to discuss donation (OR = 10.6, 95% CI, 3.35-33.9, P < 0.001). WTD did not differ by age (>60 yrs: 22/51, 43.1%; ≤60 yrs: 153/379, 40.4%, P = 0.706). Assuming all those refusing the survey would not donate, 14.4% (175/1217) were WTD for themselves, though only 7.1% (86/1217) would do so on behalf of a family member if they did not know the deceased's preference.
CONCLUSIONS: Interventions to increase knowledge and promote discussions about donation, and policies allowing widespread expression of donation preference, are needed in this setting.

Transfusão de sangue nos sistemas de saúde: do abastecimento ao consumo

Em Portugal o “Sistema Nacional de Sangue” subsiste com base numa cadeia de abastecimento de sangue assente em dádivas provenientes 100% de Dadores Voluntários não Remunerados, com um serviço nacional de sangue de base exclusivamente pública. O seu modelo organizacional assenta numa estrutura de âmbito nacional com funções de regulação, fiscalização, produção e distribuição de sangue e componentes sanguíneos às organizações de saúde públicas e privadas. Em complemento a esta rede de abastecimento existem ainda outras fontes de abastecimento, como os hospitais licenciados e outras instituições, que também procedem a todas as actividades de colheita, processamento e validação para uso final de componentes sanguíneos. Nestas situações a produção de componentes sanguíneos é realizada numa perspectiva de auto-suficiência, local ou regional, um dos princípios fundamentais de todos os serviços nacionais de sangue. Esta dissertação pretende contribuir para o conhecimento do sistema de abastecimento e consumo de sangue, aproveitando para colocar algumas questões em relação ao pode significar a gestão eficiente e eficaz da cadeia de abastecimento de sangue. A gestão eficaz da cadeia de abastecimento passa pelo conhecimento profundo da sua população de dadores, saber quem são, o que os move, quais os seus comportamentos perante a dádiva. Só assim é possível intervir eficazmente e adequar as estratégias mais eficazes à sua motivação e fidelização dádiva regular. Assim, foi efectuado um caso de estudo relativo à população de dadores do Serviço de ImunoHemoterapia do Centro Hospitalar de Vila Nova de Gaia- Espinho (CHVNG- Espinho), por forma a procurar oportunidades de melhoria nas estratégias de angariação de dadores e promoção da dádiva de sangue, acrescentando valor ao serviço e ao CHVNG-Espinho.

Hope for a peaceful death and organ donation

The therapeutic, social and economic benefits of organ transplantation are irrefutable; however, organ shortages contribute to avoidable patient deaths and burgeoning health care costs. This problem can be addressed by increasing family consent to deceased organ donation. There are high levels of community support for deceased organ donation in Australia and yet, almost fifty percent of families decline the request to donate. Increasing the number of families who agree to deceased organ donation is key to increasing national and international transplantation rates. The purpose of this study was to identify the major factors that influence a family to agree or decline deceased organ donation during the process of decision-making. The aims of the study were three-fold: to identify the key stages and the major influencers’ in the decisionmaking process; to determine if hope, deep hope and trust played a role in the decision, and to explore families’ perceptions of their decision-making experience. The study utilised an exploratory case study approach to examine the family decisionmaking process of deceased organ donation. Following ethics approval, recruitment was conducted utilising a qualitative purposive snowball strategy across Australia. A pilot study was conducted to test the study procedures prior to the main data collection, and 22 participants who had been involved in a deceased organ donation decision from nine families were interviewed. In five deaths family members had agreed to organ donation, and in four deaths the family declined. A theoretical framework based on the Precaution Adoption Process Model of decision-making was applied to propose trust, hope and deep hope underpin family organ donation decisions. Thematic analysis was conducted and three key themes comprising ‘In the fog drowning’, ‘Harvesting humanity’, and ‘It’s all up to Mum’ were revealed. The study found women, and in particular mothers, played a significant role in organ donation decision-making, and that the decision-making is bounded by family needs of trust, hope and deep hope across the continuum of time. It also found families who had their trust, hope and deep hope needs met expressed satisfaction about their decision-making experience and agreed to organ donation. Some families perceived that organ donation was a sacrifice that was too great to endure, even if the deceased had previously indicated intent to donate, and therefore declined donation. This study found that families’ ideas of a peaceful death and organ donation are not mutually exclusive. It concludes that when decision-makers’ trust and deep hope needs are met they are more willing to agree to donation. This study recommends that the idea of a ‘right’ to a peaceful death should be aligned with deceased organ donation practices and normalised.

Passive control of a bi-ventricular assist device : an experimental and numerical investigation

For the last two decades heart disease has been the highest single cause of death for the human population. With an alarming number of patients requiring heart transplant, and donations not able to satisfy the demand, treatment looks to mechanical alternatives. Rotary Ventricular Assist Devices, VADs, are miniature pumps which can be implanted alongside the heart to assist its pumping function. These constant flow devices are smaller, more efficient and promise a longer operational life than more traditional pulsatile VADs. The development of rotary VADs has focused on single pumps assisting the left ventricle only to supply blood for the body. In many patients however, failure of both ventricles demands that an additional pulsatile device be used to support the failing right ventricle. This condition renders them hospital bound while they wait for an unlikely heart donation. Reported attempts to use two rotary pumps to support both ventricles concurrently have warned of inherent haemodynamic instability. Poor balancing of the pumps’ flow rates quickly leads to vascular congestion increasing the risk of oedema and ventricular ‘suckdown’ occluding the inlet to the pump. This thesis introduces a novel Bi-Ventricular Assist Device (BiVAD) configuration where the pump outputs are passively balanced by vascular pressure. The BiVAD consists of two rotary pumps straddling the mechanical passive controller. Fluctuations in vascular pressure induce small deflections within both pumps adjusting their outputs allowing them to maintain arterial pressure. To optimise the passive controller’s interaction with the circulation, the controller’s dynamic response is optimised with a spring, mass, damper arrangement. This two part study presents a comprehensive assessment of the prototype’s ‘viability’ as a support device. Its ‘viability’ was considered based on its sensitivity to pathogenic haemodynamics and the ability of the passive response to maintain healthy circulation. The first part of the study is an experimental investigation where a prototype device was designed and built, and then tested in a pulsatile mock circulation loop. The BiVAD was subjected to a range of haemodynamic imbalances as well as a dynamic analysis to assess the functionality of the mechanical damper. The second part introduces the development of a numerical program to simulate human circulation supported by the passively controlled BiVAD. Both investigations showed that the prototype was able to mimic the native baroreceptor response. Simulating hypertension, poor flow balancing and subsequent ventricular failure during BiVAD support allowed the passive controller’s response to be assessed. Triggered by the resulting pressure imbalance, the controller responded by passively adjusting the VAD outputs in order to maintain healthy arterial pressures. This baroreceptor-like response demonstrated the inherent stability of the auto regulating BiVAD prototype. Simulating pulmonary hypertension in the more observable numerical model, however, revealed a serious issue with the passive response. The subsequent decrease in venous return into the left heart went unnoticed by the passive controller. Meanwhile the coupled nature of the passive response not only decreased RVAD output to reduce pulmonary arterial pressure, but it also increased LVAD output. Consequently, the LVAD increased fluid evacuation from the left ventricle, LV, and so actually accelerated the onset of LV collapse. It was concluded that despite the inherently stable baroreceptor-like response of the passive controller, its lack of sensitivity to venous return made it unviable in its present configuration. The study revealed a number of other important findings. Perhaps the most significant was that the reduced pulse experienced during constant flow support unbalanced the ratio of effective resistances of both vascular circuits. Even during steady rotary support therefore, the resulting ventricle volume imbalance increased the likelihood of suckdown. Additionally, mechanical damping of the passive controller’s response successfully filtered out pressure fluctuations from residual ventricular function. Finally, the importance of recognising inertial contributions to blood flow in the atria and ventricles in a numerical simulation were highlighted. This thesis documents the first attempt to create a fully auto regulated rotary cardiac assist device. Initial results encourage development of an inlet configuration sensitive to low flow such as collapsible inlet cannulae. Combining this with the existing baroreceptor-like response of the passive controller will render a highly stable passively controlled BiVAD configuration. The prototype controller’s passive interaction with the vasculature is a significant step towards a highly stable new generation of artificial heart.

The legality of tissue transplants for the benefit of family members in the UK and Australia : implications for saviour siblings

The ethics of creating ‘saviour siblings’ for the benefit of another has received much attention, but little consideration has been given to the legal position of those saviours born who may be asked to provide tissue for transplantation to another during childhood. This article examines the ethical issues surrounding minor donation as well as the existing legal framework in the UK and Australia that regulates minors providing tissue for the benefit of another. Against this background the position of minor saviours, who are called upon to donate bone marrow or peripheral blood stem cells, is examined. This analysis suggests that the law does not provide sufficient protection for minor saviours who are called upon to donate to another. It is argued that specific ethical obligations are owed to saviours—that ought to be reflected in the law—in order to protect them from exploitation while they remain minors.

Similarity not favourability : the role of donor prototypes in predicting willingness to donate organs while living

Using an extended Prototype/Willingness Model, we examined the predictors of willingness to donate an organ to a partner/family member and a stranger while living. A questionnaire assessed university students’ (N = 284) attitudes, subjective norm, prototype favourability, prototype similarity, moral norm, and willingness to donate organs in each recipient scenario. All variables, except prototype favourability, predicted willingness to donate organs in both situations. Future strategies should emphasise perceived approval from important others for living donation, the consistency of living donation with one’s own morals, and encourage perceptions of similarity between oneself and living donors to increase acceptance of living donation.
