Presumed consent will not automatically lead to increased organ donation

Early experiences of deemed consent legislation for organ donation in Nova Scotia: a qualitative study

PURPOSE

In 2021, Nova Scotia, Canada, became the first jurisdiction in North America to adopt a deemed consent organ donation system under its revised Human Organ and Tissue Donation Act. This study sought to understand the early experiences of program staff and clinicians involved in implementing this legislation.

METHODS

We conducted semistructured interviews with members of the provincial organ donation program and intensive care unit and emergency department clinicians (n = 14). Two investigators coded transcripts of interviews, then categorized the coded data into themes.

RESULTS

We identified four key themes: 1) legislation has limited impact on daily practice; 2) legislation does not address existing barriers; 3) legislation aids conversations with donor families; and 4) legislation should provide more autonomy to patients and families, not less.

CONCLUSION

Deemed consent legislation had limited impact on clinician's day-to-day practices, because of lack of infrastructure changes and infrequent donation opportunities. Nevertheless, participants felt the introduction of deemed consent in Nova Scotia eased conversations between families of potential donors and clinicians. These findings should be used to inform ongoing implementation of deemed consent and be considered by those contemplating similar legislative changes.

Donor heart selection: Evidence-based guidelines for providers

The proposed donor heart selection guidelines provide evidence-based and expert-consensus recommendations for the selection of donor hearts following brain death. These recommendations were compiled by an international panel of experts based on an extensive literature review.

Improvidence, Precaution, and the Logical-Empirical Disconnect in UK Health Policy

The last decade has seen significant developments in UK health policy, with are largely claimed to be evidence based. However, such a characterisation ought, in many cases, to be questioned. Policies can be broadly understood as based primarily on either a logical or empirical case. In the absence of relevant empirical evidence, policymakers understandably appeal to logical cases. Once such evidence is available, however, it can inform policy and enable the logical case to be set aside. Such a linear policy process is not always the reality, and logical cases often continue to guide policy decisions in direct opposition to empirical evidence. In this paper, I discuss two recent examples of this disconnect between logical and empirical cases in UK health policy. The first-organ donation-illustrates an example of a significant policy change being made in opposition to the evidence. I refer to this as the improvidence approach. The second-abortion-provides an example of policymakers not making a change that has extensive supporting data. I refer to this using the more recognisable language of the precautionary approach. Ultimately, I argue that both the improvidence and precautionary approaches are examples of problematic public policy where policymakers provide no explicit justification for going against the evidence.

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.

Ethical Solutions to the Problem of Organ Shortage

Organ shortage is a major survival issue for millions of people worldwide. Globally 1.2 million people die each year from kidney failure. In this paper, we critically examine and find lacking extant proposals for increasing organ supply, such as opting in and opt out for deceased donor organs, and parochial altruism and paired kidney exchange for live organs. We defend two ethical solutions to the problem of organ shortage. One is to make deceased donor organs automatically available for transplant without requiring consent from the donor or their relatives. The other is for society to buy nonvital organs in a strictly regulated market and provide them to people in need for free.

A Multiethnic Asian Perspective of Presumed Consent for Organ Donation: A Population-Based Perception Study

Background: Organ shortage is still a world-wide problem, resulting in long waiting lists for kidney, liver, and heart transplant candidates across many transplant centers globally. This has resulted in the move toward presumed consent to increase deceased organ donation rates. However, there remains a paucity of literature on public attitude and barriers regarding the opt-out system, with existing studies limited to Western nations. Therefore, this study aimed to understand public sentiment and different barriers toward organ donation from the perspective of Singapore, a highly diverse and multiethnic Asian society.

Methods: A cross-sectional community semi-structured interview was conducted in a public housing estate in Singapore. Pilot test was undertaken before participants were interviewed face-to-face by trained personnel. All statistical evaluations were conducted using Stata. The χ²-test compared subgroups based on patient characteristics while multivariable logistic regression identified predictors of willingness to donate/ assent. Effect estimates were quantified using odds ratio (OR).

Findings: Out of 799 individuals, 85% were agreeable to organ donation after death and 81% were willing to assent to donations of family members' organs, which declined by 16% (p < 0.001) after a clinical scenario was presented. Demographic factors including ethnicity, education, marital, and employment status affected willingness to donate and assent. Knowledge correlated significantly with willingness to donate and assent. In particular, knowledge regarding brain death irreversibility had the strongest correlation (AOR 2.15; 95% CI 1.60–2.89).

Conclusions: Organ donation rates remain low albeit presumed consent legislation, due to patient-level barriers, including but not limited to knowledge gaps, cultural values, religious backgrounds, and emotional impact at relatives' death. To effectively boost donor rates, it is crucial for policy makers to invest in public education and improve transplant provisions and family protocols.

Developments in lung transplantation over the past decade

With an improved median survival of 6.2 years, lung transplantation has become an increasingly acceptable treatment option for end-stage lung disease. Besides survival benefit, improvement of quality of life is achieved in the vast majority of patients. Many developments have taken place in the field of lung transplantation over the past decade. Broadened indication criteria and bridging techniques for patients awaiting lung transplantation have led to increased waiting lists and changes in allocation schemes worldwide. Moreover, the use of previously unacceptable donor lungs for lung transplantation has increased, with donations from donors after cardiac death, donors with increasing age and donors with positive smoking status extending the donor pool substantially. Use of ex vivo lung perfusion further increased the number of lungs suitable for lung transplantation. Nonetheless, the use of these previously unacceptable lungs did not have detrimental effects on survival and long-term graft outcomes, and has decreased waiting list mortality. To further improve long-term outcomes, strategies have been proposed to modify chronic lung allograft dysfunction progression and minimise toxic immunosuppressive effects. This review summarises the developments in clinical lung transplantation over the past decade.

Many developments have taken place in lung transplantation over the last decade: indications have broadened, donor criteria expanded, allocations systems changed, and novel therapeutic interventions implemented, leading to improved long-term survivalhttp://bit.ly/2vnpwc1

Comparison of organ donation and transplantation rates between opt-out and opt-in systems

Studies comparing opt-out and opt-in approaches to organ donation have generally suggested higher donation and transplantation rates in countries with an opt-out strategy. We compared organ donation and transplantation rates between countries with opt-out versus opt-in systems to investigate possible differences in the contemporary era. Data were analysed for 35 countries registered with the Organisation for Economic Co-operation and Development (17 countries classified as opt-out, 18 classified as opt-in) and obtained organ donation and transplantation rates for 2016 from the Global Observatory for Donation and Transplantation. Compared to opt-in countries, opt-out countries had fewer living donors per million population (4.8 versus 15.7, respectively) with no significant difference in deceased donors (20.3 versus 15.4, respectively). Overall, no significant difference was observed in rates of kidney (35.2 versus 42.3 respectively), non-renal (28.7 versus 20.9, respectively), or total solid organ transplantation (63.6 versus 61.7, respectively). In a multivariate linear regression model, an opt-out system was independently predictive of fewer living donors but was not associated with the number of deceased donors or with transplantation rates. Apart from the observed difference in the rates of living donation, our data demonstrate no significant difference in deceased donation or solid organ transplantation activity between opt-out versus opt-in countries. This suggests that other barriers to organ donation must be addressed, even in settings where consent for donation is presumed.
