Sequential improvements in organ procurement increase the organ donation rate

A Rapid Scoping Review of the Dual Advocacy Model for Donation Conversations

INTRODUCTION

Increasing family authorization for donation is critical to address the shortage of organs for transplantation, yet there is no standardized method for leading conversations with families about donation.

OBJECTIVE

The aim of this rapid scoping review is to identify research assessing the components of dual advocacy, a model to discuss organ donation with grieving families.

METHODS

PubMed, Web of Science, and grey literature were searched for studies published from 2012 to the present. Data representing the various dual advocacy components that were empirically tested were extracted. Outcomes of interest were authorization for organ donation or family satisfaction with the donation conversation.

RESULTS

Twenty-two articles were identified that tested at least one component of dual advocacy. The most commonly tested component was effective communication about donation (N = 9), including explaining brain death and the donation process. The primary outcome for the majority of studies was donation authorization or conversion rates. Studies that tested all components of dual advocacy (N = 9) had overall positive results while studies that tested a single component had mixed results.

DISCUSSION

Although family authorization to donation is critical to addressing the national organ shortage, there has yet to be a standardized method for leading families in the organ donation conversation. Despite the need for organ transplantation in the United States and worldwide, few large-scale studies have rigorously tested the most effective ways to engage families of donor-eligible patients about the organ donation opportunity. There is an urgent need for further research to establish a standard of evidence-based practice.

Systematic review of hospital-level metrics and interventions to increase deceased organ donation

BACKGROUND

Efforts to ameliorate the organ shortage have predominantly focused on improving processes and interventions at multiple levels in the organ donation process, but no comprehensive review of hospital-level features contributing to organ donation exists. We undertook a systematic review of the literature to better understand current knowledge and knowledge gaps about hospital-level metrics and interventions associated with successful organ donation.

METHODS

We searched six electronic databases (PubMed, Embase, CINAHL, Web of Science, Health Business Elite, and Google scholar) and conference abstracts for articles on hospital-level features associated with the final outcome of organ donation (PROSPERO CRD42020187080). Editorials, letters to the editor, and reviews without original data were excluded. Our main outcomes were conversion rate, donation rate, number of organs recovered, number of donors, and authorization rate.

RESULTS

Our search yielded 2177 studies, and after a thorough assessment, 72 articles were included in this systematic review. Studies were thematically categorized into 1) Hospital-level interventions associated with metrics of organ donation; these included patient- and family-centric measures (i.e. standardized interviews, collaborative requesting and decoupling, and dedicated in-house coordinators), and donor management goals that significantly increased conversion rates by up to 64%; 2) Hospital-level multi-stage programs/policies; which increased authorization rates between 30 and 50%; and 3) Hospital characteristics and qualities; being an academic center, trauma center and larger hospital correlated with higher authorization and conversion rates. Most studies had considerable risk of bias and were of low quality.

CONCLUSIONS

There is a lack of well-designed studies on hospital-level metrics and interventions associated with organ donation. The use of thoughtful, patient- and family-centric approaches to authorization generally is associated with more organ donors. Future work can build on what is known about the hospital role in organ donation to improve the entire organ donation process.

The development and current status of Intensive Care Unit management of prospective organ donors

Introduction:

Despite continuous advances in transplant medicine, there is a persistent worldwide shortage of organs available for donation. There is a growing body of research that supports that optimal management of deceased organ donors in Intensive Care Unit can substantially increase the availability of organs for transplant and improve outcomes in transplant recipients.

Methods:

A systematic literature review was performed, comprising a comprehensive search of the PubMed database for relevant terms, as well as individual assessment of references included in large original investigations, and comprehensive society guidelines.

Results:

In addition to overall adherence to catastrophic brain injury guidelines, optimization of physiologic state in accordance with established donor management goals (DMGs), and establishment of system-wide processes for ensuring early referral to organ procurement organizations (OPOs), several specific critical care management strategies have been associated with improved rates and outcomes of renal transplantation from deceased donors. These include vasoactive medication selection, maintenance of euvolemia, avoidance of hydroxyethyl starch, glycemic control, targeted temperature management, and blood transfusions if indicated.

Conclusions:

Management of deceased organ donors should focus first on maintaining adequate perfusion to all organ systems through adherence to standard critical care guidelines, early referral to OPOs, and family support. Furthermore, several specific DMGs and strategies have been recently shown to improve both the rates and outcomes of organ transplantation.

Treating the donor

PURPOSE OF REVIEW

Current pressures of organ supply and demand require maximization of potential for organ donation. The donor population is older and has more significant comorbidity than in the past.Optimal management of the donor after brain death (DBD) is essential to ensure that the greatest number of organs can be transplanted per donor. Defining evidence-based drugs and techniques to assist this has never been more important.

RECENT FINDINGS

Care of patients with catastrophic brain injury incorporating supportive therapy targeted at specific goals and delivered by experienced specialists provides the best donation outcomes. Such pathways represent best practice critical care applied to this population. In this context, the value of some previously recommended therapies appears questionable and warrants reassessment. Prolonged (>24 h) incorporeal organ conditioning may have significant benefits.Extracorporeal support in the resuscitation arena is emerging and, in patients who fail to respond, may yield a new source of donors.

SUMMARY

Early identification of potential DBD, best practice critical care, and achieving defined treatment goals are associated with more transplantable organs. Study of a complex intervention like donor management presents significant problems of organization, ethics and consent. This situation is recognized internationally and progress is being made.

Transparency and accountability in mass media campaigns about organ donation: a response to Morgan and Feeley

We respond to Morgan and Feeley's critique on our article "Mass Media in Organ Donation: Managing Conflicting Messages and Interests." We noted that Morgan and Feeley agree with the position that the primary aims of media campaigns are: "to educate the general public about organ donation process" and "help individuals make informed decisions" about organ donation. For those reasons, the educational messages in media campaigns should not be restricted to "information from pilot work or focus groups" but should include evidence-based facts resulting from a comprehensive literature research. We consider the controversial aspects about organ donation to be relevant, if not necessary, educational materials that must be disclosed in media campaigns to comply with the legal and moral requirements of informed consent. With that perspective in mind, we address the validity of Morgan and Feeley's claim that media campaigns have no need for informing the public about the controversial nature of death determination in organ donation. Scientific evidence has proven that the criteria for death determination are inconsistent with the Uniform Determination of Death Act and therefore potentially harmful to donors. The decision by campaign designers to use the statutory definition of death without disclosing the current controversies surrounding that definition does not contribute to improved informed decision making. We argue that if Morgan and Feeley accept the important role of media campaigns to enhance informed decision making, then critical controversies should be disclosed. In support of that premise, we will outline: (1) the wide-spread scientific challenges to brain death as a concept of death; (2) the influence of the donor registry and team-huddling on the medical care of potential donors; (3) the use of authorization rather than informed consent for donor registration; (4) the contemporary religious controversy; and (5) the effects of training desk clerks as organ requestors at the Department of Motor Vehicles offices. We conclude that organ donation is a medical procedure subject to all the ethical obligations that the medical profession must uphold including that of transparency and truthfulness.
