Systematic review of attitudes toward donation after cardiac death among healthcare providers and the general public

Tensions between end-of-life care and organ donation in controlled donation after circulatory death: ICU healthcare professionals experiences

BACKGROUND

The development of controlled donation after circulatory death (cDCD) is both important and challenging. The tension between end-of-life care and organ donation raises significant ethical issues for healthcare professionals in the intensive care unit (ICU). The aim of this prospective, multicenter, observational study is to better understand ICU physicians' and nurses' experiences with cDCD.

METHODS

In 32 ICUs in France, ICU physicians and nurses were invited to complete a questionnaire after the death of end-of-life ICU patients identified as potential cDCD donors who had either experienced the withdrawal of life-sustaining therapies alone or with planned organ donation (OD(-) and OD( +) groups). The primary objective was to assess their anxiety (State Anxiety Inventory STAI Y-A) following the death of a potential cDCD donor. Secondary objectives were to explore potential tensions experienced between end-of-life care and organ donation.

RESULTS

Two hundred six ICU healthcare professionals (79 physicians and 127 nurses) were included in the course of 79 potential cDCD donor situations. STAI Y-A did not differ between the OD(-) and OD( +) groups for either physicians or nurses (STAI Y-A were 34 (27-38) in OD(-) vs. 32 (27-40) in OD( +), p = 0.911, for physicians and 32 (25-37) in OD(-) vs. 39 (26-37) in OD( +), p = 0.875, for nurses). The possibility of organ donation was a factor influencing the WLST decision for nurses only, and a factor influencing the WLST implementation for both nurses and physicians. cDCD experience is perceived positively by ICU healthcare professionals overall.

CONCLUSIONS

cDCD does not increase anxiety in ICU healthcare professionals compared to other situations of WLST. WLST and cDCD procedures could further be improved by supporting professionals in making their intentions clear between end-of-life support and the success of organ donation, and when needed, by enhancing communication between ICU physician and nurses.

Cognitive and non-cognitive factors affecting decision-making about deceased organ donation in Italy: a systematic review

INTRODUCTION

Decision-making about organ donation (OD) is influenced by interrelated cognitive and non-cognitive factors. The identification of these factors in the general population and among healthcare professionals (HCP) in Italy are key ethical and scientific requirements to inform targeted communication and policy-making interventions, and to promote decision-making processes that are truly informed.

EVIDENCE ACQUISITION

A systematic review of articles published between January 1, 1999, and January 31, 2024 was performed by searching four databases using these terms: "organ donation" AND (attitude OR opinion OR knowledge OR awareness OR intention OR beliefs OR norms OR perception) AND (Italy OR Italian). The reference sections of included articles were scrutinized for additional references.

EVIDENCE SYNTHESIS

Most respondents (lay citizens and HCPs) were in favor of OD, but many (mainly but not exclusively lay citizens) would not authorize OD in the event of death of a family member. Lack of knowledge about OD and the gap between demand and supply of organs, fear of body mutilation, doubts about the criteria for brain death diagnosis, doubts about the wishes of the deceased family member, and distrust towards medical doctors and the healthcare system were the most commonly reported reasons, confirming that cognitive and non-cognitive factors are at play.

CONCLUSIONS

The majority of the Italian population supports OD, but cognitive and non-cognitive barriers are present even among HCPs. Communication campaigns, encouraging family discussions about OD, providing better education for HCPs (including medical and nursing students), and making it easier to sign OD cards may promote informed decision-making and possibly increase consent rates.

Advancing the Scientific Basis for Determining Death in Controlled Organ Donation After Circulatory Determination of Death

In controlled organ donation after circulatory determination of death (cDCDD), accurate and timely death determination is critical, yet knowledge gaps persist. Further research to improve the science of defining and determining death by circulatory criteria is therefore warranted. In a workshop sponsored by the National Heart, Lung, and Blood Institute, experts identified research opportunities pertaining to scientific, conceptual, and ethical understandings of DCDD and associated technologies. This article identifies a research strategy to inform the biomedical definition of death, the criteria for its determination, and circulatory death determination in cDCDD. Highlighting knowledge gaps, we propose that further research is needed to inform the observation period following cessation of circulation in pediatric and neonatal populations, the temporal relationship between the cessation of brain and circulatory function after the withdrawal of life-sustaining measures in all patient populations, and the minimal pulse pressures that sustain brain blood flow, perfusion, activity, and function. Additionally, accurate predictive tools to estimate time to asystole following the withdrawal of treatment and alternative monitoring modalities to establish the cessation of circulatory, brainstem, and brain function are needed. The physiologic and conceptual implications of postmortem interventions that resume circulation in cDCDD donors likewise demand attention to inform organ recovery practices. Finally, because jurisdictionally variable definitions of death and the criteria for its determination may impede collaborative research efforts, further work is required to achieve consensus on the physiologic and conceptual rationale for defining and determining death after circulatory arrest.

Attitude of the Older Population Toward Controlled Asystole Donation

INTRODUCTION

Studies about the knowledge of and attitude toward new lines of organ donation in a group of older people are important due to the increase in older organ donors.

OBJECTIVES

To analyze the attitude of citizens over 65 years of age in southeastern Spain toward controlled asystole donation (CAD) and to determine the psycho-social profile that influences this attitude.

METHODS

The study population consisted of citizens over 65 years of age. A representative sample was obtained in southeastern Spain (N = 420). A questionnaire about attitudes toward CAD was used, detailing in the questionnaire that this is a type of donation from people who have died of circulatory and respiratory criteria after the limitation of life support treatment. Several psychosocial variables were also taken into account. Statistical analysis included the χ2 test and multivariate analysis.

RESULTS

The completion rate was 84% (n = 351). Favorable attitude toward organ donation and transplantation (ODT) was 98% (n = 344) overall, and CAD was viewed favorably by 45% (n = 158). The psychosocial variables that influenced attitude toward CAD were mainly having received a talk about ODT (odds ratio [OR] 5.6), knowing the opinion of one's partner (OR 7.95), acceptance of cremation (OR 1.09), and acceptance of autopsy (OR 3.002).

CONCLUSIONS

The attitude of older people toward CAD is unfavorable despite a willingness to support ODT in general. This attitude is influenced by variables of social and family dialogue about ODT, attitude to body manipulation, and having received information about ODT.

Ethics of non-therapeutic research on imminently dying patients in the intensive care unit

Non-therapeutic research with imminently dying patients in intensive care presents complex ethical issues. The vulnerabilities of the imminently dying, together with societal disquiet around death and dying, contribute to an intuition that such research is beyond the legitimate scope of scientific inquiry. Yet excluding imminently dying patients from research hinders the advancement of medical science to the detriment of future patients. Building on existing ethical guidelines for research, we propose a framework for the ethical design and conduct of research involving the imminently dying. To enable rapid translation to practice, we frame the approach in the form of eight ethical questions that researchers and research ethics committees ought to answer prior to conducting any research with this patient population. (1) Does the study hypothesis require the inclusion of imminently dying patients? (2) Are non-therapeutic risks and burdens minimised consistent with sound scientific design? (3) Are the risks of these procedures no more than minimal risk? (4) Are these non-therapeutic risks justified insofar as they are reasonable in relation to the anticipated benefits of the study? (5) Will valid informed consent be obtained from an authorised surrogate decision maker? (6) How will incidental findings be handled? (7) What additional steps are in place to protect families and significant others of research participants? (8) What additional steps are in place to protect clinical staff and researchers? Several ethical challenges hinder research with imminently dying patients. Nonetheless, provided adequate protections are in place, non-therapeutic research with imminently dying patients is ethically justifiable. Applying our framework to an ongoing study, we demonstrate how our question-driven approach is well suited to guiding investigators and research ethics committees.

Neurologic Physiology after Removal of Therapy (NeuPaRT) study: study protocol of a multicentre, prospective, observational, pilot feasibility study of neurophysiology after withdrawal of life-sustaining measures

INTRODUCTION

In donation after circulatory determination of death, death is declared 5 min after circulatory arrest. This practice assumes, but does not explicitly confirm, permanent loss of brain activity. While this assumption is rooted a strong physiological rationale, paucity of direct human data regarding temporal relationship between cessation of brain activity and circulatory arrest during the dying process threatens public and healthcare provider trust in deceased organ donation.

METHODS AND ANALYSIS

In this cohort study, we will prospectively record cerebral and brainstem electrical activity, cerebral blood flow velocity and arterial blood pressure using electroencephalography (EEG), brainstem evoked potentials, transcranial doppler and bedside haemodynamic monitors in adult patients undergoing planned withdrawal of life sustaining measures in the intensive care units at five hospital sites for 18 months. We will use MATLAB to synchronise waveform data and compute the time of cessation of each signal relative to circulatory arrest. Our primary outcome is the feasibility of patient accrual, while secondary outcomes are (a) proportion of patients with complete waveform recordings and data transfer to coordinating site and (b) time difference between cessation of neurophysiological signals and circulatory arrest. We expect to accrue 1 patient/site/month for a total of 90 patients.

ETHICS AND DISSEMINATION

We have ethics approval from Clinical Trials Ontario (protocol #3862, version 1.0, date 19 January 2022.) and the relevant Research Ethics Board for each site. We will obtain written informed consent from legal substitute decision makers. We will present study results at research conferences including donor family partner forum and in peer-reviewed publications.

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.

The Effect of Educational Initiatives on the Attitude and Knowledge of Health Care Professionals Regarding Organ Donation and Transplantation: An Integrative Literature Review

BACKGROUND

This integrative literature review synthesizes evidence on the effect of educational initiatives (EI) on the attitude and knowledge of health care professionals regarding organ donation and transplantation (ODT), and the EI effect considering the risks of the ODT process related to the professionals' attitudes and knowledge.

METHODS

This search included 8 databases, with search terms across 4 groups: ODT activities, health professionals, attitude/knowledge, and EI. We applied the PICO framework to select articles: Population - health care professionals; Intervention - any EI; Comparison - pre/post or intervention/control designs; and Outcomes - indicators of attitudes or knowledge toward ODT. After the appraisal of 2,221 citations, 21 studies were included in this review.

RESULTS

The EI varied to a great extent in terms of format (seminars, workshops, video lectures; online or in-person training), duration (from 15 minutes to 3 months), and the number of participants (from 12 to 1011). The effects reported were positive, increasing professionals' knowledge and attitude regarding the ODT process for all EI formats. Most articles (14; 67%) presented positive results with statistical significance for all indicators analyzed, and the remaining studies (7; 35%) reported statistical significance for some of the indicators analyzed. All EIs focused on donation or post-transplantation activities, lacking studies on the transplantation stage.

CONCLUSIONS

Results suggest that different types of EIs may positively affect the attitude and knowledge of health care professionals regarding the ODT process. This study provides an up-to-date overview of the main themes examined in this literature, highlighting critical knowledge gaps and methodological flaws.

Cerebral cortical activity after withdrawal of life-sustaining measures in critically ill patients

Establishing when cerebral cortical activity stops relative to circulatory arrest during the dying process will enhance trust in donation after circulatory determination of death. We used continuous electroencephalography and arterial blood pressure monitoring prior to withdrawal of life sustaining measures and for 30 min following circulatory arrest to explore the temporal relationship between cessation of cerebral cortical activity and circulatory arrest. Qualitative and quantitative EEG analyses were completed. Among 140 screened patients, 52 were eligible, 15 were enrolled, 11 completed the full study, and 8 (3 female, median age 68 years) were included in the analysis. Across participants, EEG activity stopped at a median of 78 (Q1 = -387, Q3 = 111) seconds before circulatory arrest. Following withdrawal of life sustaining measures there was a progressive reduction in electroencephalographic amplitude (p = .002), spectral power (p = .008), and coherence (p = .003). Prospective recording of cerebral cortical activity in imminently dying patients is feasible. Our results from this small cohort suggest that cerebral cortical activity does not persist after circulatory arrest. Confirmation of these findings in a larger multicenter study are needed to help promote stakeholder trust in donation after circulatory determination of death.

"A Delicate balance"-Perceptions and Experiences of ICU Physicians and Nurses Regarding Controlled Donation After Circulatory Death. A Qualitative Study

Controlled donation after circulatory death (cDCD) is considered by many as a potential response to the scarcity of donor organs. However, healthcare professionals may feel uncomfortable as end-of-life care and organ donation overlap in cDCD, creating a potential barrier to its development. The aim of this qualitative study was to gain insight on the perceptions and experiences of intensive care units (ICU) physicians and nurses regarding cDCD. We used thematic analysis of in-depth semi-structured interviews and 6-month field observation in a large teaching hospital. 17 staff members (8 physicians and 9 nurses) participated in the study. Analysis showed a gap between ethical principles and routine clinical practice, with a delicate balance between end-of-life care and organ donation. This tension arises at three critical moments: during the decision-making process leading to the withdrawal of life-sustaining treatments (LST), during the period between the decision to withdraw LST and its actual implementation, and during the dying and death process. Our findings shed light on the strategies developed by healthcare professionals to solve these ethical tensions and to cope with the emotional ambiguities. cDCD implementation in routine practice requires a shared understanding of the tradeoff between end-of-life care and organ donation within ICU.

Public Understandings of the Definition and Determination of Death: A Scoping Review

Background.

Advances in medicine and technology that have made it possible to support, repair, or replace failing organs challenge commonly held notions of life and death. The objective of this review is to develop a comprehensive description of the current understandings of the public regarding the meaning/definition and determination of death.

Methods.

This scoping review was conducted in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist. Online databases were used to identify articles published from 2003 to 2021. Two reviewers (S.S. and K.Z.) screened the articles using predefined inclusion and exclusion criteria, extracted data for specific content variables, and performed descriptive examination. Complementary searches of reference lists complemented the final study selection. A search strategy using vocabulary of the respective databases was created, and criteria for the inclusion and exclusion of the articles were established.

Results.

Seven thousand four hundred twenty-eight references were identified. Sixty were retained for analysis, with 4 additional references added from complementary searches. A data extraction instrument was developed to iteratively chart the results. A qualitative approach was conducted to thematically analyze the data. Themes included public understanding/attitudes toward death and determination of death (neurological determination and cardiocirculatory determination of death), death and organ donation, public trust and legal variability, and media impacts.

Conclusions.

This review provides a current and comprehensive overview of the literature related to the general public’s understanding and attitudes toward death and death determination and serves to highlight the gaps in this topic.

A Systematic Review of Qualitative Studies Investigating Motives and Experiences of Recipients of Anonymous Gamete Donation

The decision to use an anonymous gamete donation in fertility treatment could have significant long-term psychological and social effects for all stakeholders involved. In light of the growing recognition of donor-conceived children's right to know their genetic parentage, this entails profound ethical implications. This review aims to carve out the full spectrum of recipients' motives and experiences related to donor anonymity which could serve as an analytical framework for future ethical and sociological research on issues of donor anonymity. This review was conducted following a seven-step approach for systematic reviews of empirical bioethics literature. The characteristics and quality of the studies included in this review were reported. Data analysis was conducted using qualitative content analysis and was informed by sociological functionalist theorizations of ignorance. The 53 studies selected showed a diverse spectrum of characteristics concerning date and country of study, methodology, family type of participants, sample size, and the timing of data collection in relation to the stage of treatment. A total of 22 categories of motives and experiences of recipients concerning donor anonymity were identified inductively and grouped into five main categories. Donor anonymity was identified as a eufunctional form of ignorance, by which the recipients experienced or intended to control, regulate, or protect inter-stakeholder relations. Interpreting recipients' motives and experiences concerning donor anonymity as a form of ignorance directed toward particular stakeholders helps reframe the discourse on donor anonymity. It is a fruitful approach that can be refined further and applied in future research. This review identified possible directions for future investigations on motives for donor anonymity: the need for more thorough inquiries into the change in recipients' preferences over time, such as in the form of longitudinal studies and research on the perspective of non-biological parents.

Presumed post-mortem donors: the degree of information among university students

BACKGROUND

Organ transplantation represents the most effective and acceptable therapy for end-stage organ failure. However, its frequent practice often leads to a shortage of organs worldwide. To solve this dilemma, some countries, such as Portugal, have switched from an opt-in to an opt-out system, which has raised concerns about respect for individual autonomy. We aimed to evaluate whether young university students are aware of this opt-out system so that they can make informed, autonomous and conscious decisions, as well as to identify the factors that determine a positive attitude toward post-mortem organ donation.

METHODS

An observational, cross-sectional study was developed and a questionnaire was administered to first-year students from six faculties of the University of Porto.

RESULTS

Of the 841 participants, 60% were unaware that Portugal had adopted an opt-out system. Among the informed individuals, their main sources of information included social media, internet, and family. Furthermore, only 48% of all participants agreed with the current opt-out system. Female sex (p = 0.049; OR 1.393), knowledge of the law (p < 0.001; OR 4.749) and family being the primary source of information (p < 0.001; OR 2.855) were independent factors associated with a positive attitude toward post-mortem organ donation law.

CONCLUSIONS

There is a significant lack of knowledge among young university students regarding the presumed post-mortem organ donation law and how it works. Female sex, having family as a primary source of information and being aware of the presumed post-mortem organ donation law are the strongest independent factors that determine a positive attitude toward the opt-out system.

Fifteen-minute consultation: Paediatric organ and tissue donation

This article explores ways in which paediatricians can help increase awareness and embed organ and tissue donation in the end-of-life care process. This can save patient lives on the organ transplant waiting list, many of whom currently die prematurely. The information benefits multidisciplinary staff including doctors, nurses and allied professionals to (1) recognise triggers for making referral to the specialist nurse for organ donation in order to make timely assessment for suitability for organ and/or tissue donation, (2) plan a multidisciplinary approach for families to make decisions for the gift of life and (3) help provide on-going support to families and staff.

Comparison of pediatric brain-dead donors to donation after circulatory death donors in the United States

In pediatrics, an increasing need for transplantable organs exists. This study aimed to describe the epidemiology of pediatric deceased donors in the United States. This retrospective observational study utilized data from the Organ Procurement and Transplantation Network (OPTN) from 2000 to 2015. Patients were stratified based on method of organ donation. Demographic variables and mechanism of death were then compared. A total of 14,481 deceased pediatric organ donors, donation after brain death (DBD) and donation after circulatory death (DCD), were included in the study, of which 8% were DCD donors. A significant difference (p<0.001) existed between the two donor groups with respect to ethnicity and mechanism of death. The annual trend of DCD and DBD donors showed an inverse relationship. During the 15-year study period the number of DBD donors decreased from 985 to 785 per year while DCD donors increased from 15 to 146 per year. As well, overall organs transplanted per year decreased from 3,475 to 3,117 over the 15-year study period. Significant differences exist between pediatric DBD donors and DCD donors, specifically with respect to ethnicity and mechanism of death. The number of pediatric DBD donors is decreasing while the number of pediatric DCD is slowly rising, making it increasingly important to be able to characterize these donors to better identify eligible DCD donors to optimize organ utilization.

Survey of public attitudes towards imminent death donation in the United States

Imminent death donation (IDD) is described as living organ donation prior to a planned withdrawal of life-sustaining care in an imminently dying patient. Although IDD was ethically justified by United Network for Organ Sharing, the concept remains controversial due to presumed lack of public support. The aim of this study was to evaluate the public's attitudes towards IDD. A cross-sectional survey was conducted of US adults age >18 years (n = 2644). The survey included a case scenario of a patient with a devastating brain injury. Responses were assessed on a 5-point Likert scale. Results showed that 68% - 74% of participants agreed or strongly agreed with IDD when posed as a general question and in relation to the case scenario. Participants were concerned about "recovery after a devastating brain injury" (34%), and that "doctors would not try as hard to save a patient's life" (33%). Only 9% of participants would be less likely to trust the organ donation process. In conclusion, our study demonstrates strong public support for IDD in the case of a patient with a devastating brain injury. Notably, participants were not largely concerned with losing trust in the organ donation process. These results justify policy change towards imminent death donation.

Prioritizing Factors Affecting Deceased Organ Donation in Malaysia: Is a New Organ Donation System Required?

Purpose

The gap between the demand and the supply of human organs for transplantation is on the rise in Malaysia, despite the efforts of governments to promote donor registration. Factors affecting willingness to donate are contextual and vary from country to country. This research mainly focuses on the selection of most suitable organ donation system through factors affecting willingness to donate in Malaysia. The objectives of this study are to prioritize those factors acting as the pillars of the organ donation system and further to select the most suitable organ donation system for Malaysia.

Patients and Methods

The data were collected from 35 experts by using a bipolar questionnaire. The study applied an analytical hierarchal process (AHP) for prioritization factors contributing to willingness to donate and then selection of a suitable organ donation system based on prioritized factors.

Results

Based on the AHP results, it is evident that donation perception (0.36) has the highest priority in influencing organ donation rates, followed by socioeconomic status (0.32), demographic factors (0.23), and financial incentives (0.09). Further, our results challenge the existing opt-in donation system in Malaysia and present a presumptive approach as a suitable system for increasing deceased donation rate in Malaysia. Presumptive approach promotes the role of health-care professionals in securing the family consent.

Conclusion

This approach is a person-oriented rather than process-oriented strategy and it relies on designated requesters' skills to evoke altruism among bereaved families. Based on results, the authors recommended that relevant government agencies focus on training nurses to discuss donation with bereaved families and raising public awareness.

Online education about end-of-life care and the donation process after brain death and circulatory death. Can we influence perception and attitudes in critical care doctors? A prospective study

Impact of training on end-of-life care (EOLC) and the deceased donation process in critical care physicians' perceptions and attitudes was analysed. A survey on attitudes and perceptions of deceased donation as part of the EOLC process was delivered to 535 physicians working in critical care before and after completion of a online training programme (2015-17). After training, more participants agreed that nursing staff should be involved in the end-of-life decision process (P < 0.001) and that relatives should not be responsible for medical decisions (P < 0.001). Postcourse, more participants considered 'withdrawal/withholding' as similar actions (P < 0.001); deemed appropriate the use of pre-emptive sedation in all patients undergoing life support treatment adequacy (LSTA; P < 0.001); and were favourable to approaching family about donation upon LSTA agreement, as well as admitting them in the intensive care unit (P < 0.001) to allow the possibility of donation. Education increased the number of participants prone to initiate measures to preserve the organs for donation before the declaration of death in patients undergoing LSTA (P < 0.001). Training increased number of positive terms selected by participants to describe donation after brain and circulatory death. Training programmes may be useful to improve physicians' perception and attitude about including donation as part of the patient's EOLC.

Pediatric donation after circulatory determination of death (pDCD): A narrative review

Pediatric donation after circulatory death (pDCD) is an established pathway for organ donation. It remains, however, a relatively rare event worldwide, and most clinicians outside of the pediatric intensive care unit (PICU) are unfamiliar with it. The goal of this review is to introduce the processes and concepts of pDCD. While most children die in circumstances that would not allow pDCD, many children that die after withdrawal of life sustaining therapy (WLST) may be eligible for donation of some organs. The potential benefits of this practice to patients on the wait list are well known, but donation can also be an opportunity to honor a patient's or family's desire to altruistically improve the lives of others. Offering the possibility of donation requires careful attention to ethical principles to ensure that conflicts of interest are avoided and that the family is free to make an independent, fully informed decision. Doing so allows families and decision makers the autonomy to decide if donation is something they wish to incorporate into end-of-life care.

Attitudes and self-reported end-of-life care of Australian and New Zealand intensive care doctors in the context of organ donation after circulatory death

The incidence of organ donation after circulatory death (DCD) in Australia and New Zealand (ANZ) has steadily increased in recent years. Intensive care doctors are vital to the implementation of DCD and healthcare professionals' attitudes to DCD can influence their participation. In order to determine ANZ intensive care doctors' attitudes to DCD, to explore if demographic characteristics influence attitude to DCD and to assess if attitude to DCD can predict palliative prescription rationale at the end of life of DCD donors, a cross-sectional online survey was distributed to ANZ intensive care doctors and responses collected between 29 April and 10 June 2016. Exploratory factor analysis was used to define various attributes of attitude to DCD. Results were subjected to comparative statistical analyses to examine the relation between demographic data and attitude to DCD. Multiple regression models were used to examine if attitude to DCD could predict intensive care doctors' palliative prescription rationales at the end of life of DCD donors. One hundred and sixty-one intensive care doctors responded to the survey with 69.4% having worked in intensive care for ten years or more. Respondents responded positively to the support of and perceived importance of DCD in helping those who would benefit from the donations (constructive attributes)(mean composite factor score = 3.84, standard deviation [SD] 0.83), they positively perceived that conducive and facilitative orchestration of DCD helps families cope (mean composite factor score = 3.94, SD 0.72) and that they would manage a DCD donor similar to any patient at the end of their life (mean score = 3.94, SD 0.72). Respondents responded negatively to having concerns that the circulatory death of potential DCD donors does not occur within the specified time frame (mean score = 2.28, SD 1.02). There was an association between organ donation professional education courses, familiarity with national guidelines and positive attitudes to certain attributes of attitude to DCD. Regression models demonstrated the attitude to DCD may predict intensive care doctors' palliative medication prescription rationales at the end of life of the DCD donor. Intensive care doctors in ANZ adopt a morally neutral attitude to DCD where they recognise the importance of organ donation, and support and conduct DCD as a part of good end-of-life care.

Decision-making in end of life care. Are we really playing together in the same team?

BACKGROUND

Limitation of life-sustaining treatment is increasingly common in critical care units, and controlled donation after circulatory death is starting to be included as an option within patient care plans. Lack of knowledge and misunderstandings can place a barrier between healthcare professionals.

OBJECTIVE

To determine the perceptions, knowledge and attitudes of physicians and nurses working in intensive care units regarding Limitation of life-sustaining treatment and controlled donation after circulatory death.

DESIGN, SETTINGS AND PARTICIPANTS

Cross-sectional study carried out in 13 Spanish hospitals by means of an ad hoc questionnaire.

METHODS

Contingency tables, Pearson's chi-squared test, Student's t-test and the Mann-Whitney u-test were used to carry out descriptive, bivariate and multivariate statistical analyses of responses.

RESULTS

Although Limitation of life-sustaining treatment is a widespread practice, the survey revealed that nurses feel excluded from the development of protocols and the decision-making process, whilst the perception of physicians is that they have greater knowledge of the topic, and decisions are reached in consensus.

CONCLUSIONS

Multi-disciplinary training programmes can help critical healthcare providers to work together with greater coordination, thus benefitting patients and their next of kin by providing excellent end-of-life care.

Measuring Critical Care Providers' Attitudes About Controlled Donation After Circulatory Death

INTRODUCTION

Unfavorable attitudes and insufficient knowledge about donation after cardiac death among critical care providers can have important consequences for the appropriate identification of potential donors, consistent implementation of donation after cardiac death policies, and relative strength of support for this type of donation. The lack of reliable and valid assessment measures has hampered research to capture providers' attitudes. Design and Research Aims: Using stakeholder engagement and an iterative process, we developed a questionnaire to measure attitudes of donation after cardiac death in critical care providers (n = 112) and examined its psychometric properties. Exploratory factor analysis, internal consistency, and validity analyses were conducted to examine the measure.

RESULTS

A 34-item questionnaire consisting of 4 factors (Personal Comfort, Process Satisfaction, Family Comfort, and System Trust) provided the most parsimonious fit. Internal consistency was acceptable for each of the subscales and the total questionnaire (Cronbach α > .70). A strong association between more favorable attitudes overall and knowledge ( r = .43, P < .001) provides evidence of convergent validity. Multivariable regression analyses showed that white race ( P = .002) and more experience with donation after cardiac death ( P < .001) were significant predictors of more favorable attitudes.

CONCLUSION

Study findings support the utility, reliability, and validity of a questionnaire for measuring attitudes in critical care providers and for isolating targets for additional education on donation after cardiac death.

Impact of training on intensive care providers' attitudes and knowledge regarding limitation of life-support treatment and organ donation after circulatory death

The limitation of life-sustaining treatment is common practice in critical care units, and organ donation after circulatory death has come to be included as an option within this care plan. Lack of knowledge and misunderstandings can raise barriers between health-care providers (e.g., confusion about professional roles, lack of collaboration, doubts about the legality of the process, and not respecting patients' wishes in the decision-making process). The aim of the present study was to determine the knowledge and attitudes of intensive care physicians and nurses before and after a multidisciplinary online training program. A cross-sectional study was performed, and comparisons between the two groups were made using a χ² -test for categorical data and unpaired t-test or Mann-Whitney rank sum test for continuous data according to its distribution. Training benefited both professional categories, helping nurses to be more open-minded and willing to collaborate, while physicians became more aware of nurses' presence and the need to collaborate with them.

A Comparison of Request Process and Outcomes in Donation After Cardiac Death and Donation After Brain Death: Results From a National Study

Available literature points to healthcare providers' discomfort with donation after cardiac death (DCD) and their perception of public reluctance toward the procedure. Using a national sample, we report on the communication content of actual DCD and donation after brain death (DBD) approaches by organ procurement organization (OPO) requesters and compare family decision makers' (FDMs') experiences of both modalities. We recruited 1601 FDMs using a validated protocol; 347 (21.7%) were of potential DCD donors. Semistructured telephone interviews yielded FDMs' sociodemographic data, donation attitudes, assessment of approach, final outcomes, and substantiating reasons. Initial analysis consisted of bivariate analyses. Multilevel mixture models compared groups representing authorization outcome and DCD/DBD status. No significant differences in family authorization were found between DCD and DBD cases. Statistically significant associations were found between sociodemographic characteristics and authorization, with white FDMs more likely to authorize DCD or DBD than black FDMs. FDMs of both modalities had similar evaluations of requester skills, topics discussed, satisfaction, and refusal reasons. The findings suggest that the DCD/DBD distinction may not be notable to families. We recommend the use of similar approach strategies and communication skills and the development of education campaigns about the public's acceptance of DCD.

Factors Associated With HIV Testing in Youth in the United States: An Integrative Review

We used an integrative review to synthesize existing literature on the factors associated with HIV testing by youth ages 13 to 24 years in the United States. PubMed, CINAHL, PsycINFO, and Google Scholar were systematically searched and 44 original research studies met our criteria. A directed qualitative content analysis was conducted to integrate findings according to the personal, relationship, community, and society levels of the social-ecological model. Female gender, African American race, age, and physical illness were some of the factors more consistently associated with HIV testing. Modifiable factors such as fear, drug use, poor condom use, partner communication, and multiple sexual partners were also noted as influencing HIV testing in youth. Our integrative review revealed gaps in the literature that need further exploration, particularly in the area of community and society influences on HIV testing for youth. Implications for research, practice, and policy are discussed.

Views of health care personnel on organ donation and transplantation: A literature review

The purpose of this study was to review the empirical studies on health personnel's views towards organ donation and transplantation. A scoping review was carried out in English, Portuguese and Spanish. The search was conducted in eight databases, and two search engines. Four groups of descriptors were used. The period covered was 1985 to 2013. Frequency and content analysis was performed. Two hundred forty-eight articles were selected, out of 316 identified. The literature is temporally and geographically clustered. Quantitative studies predominate. The studies prioritized the perspective of medical and nursing personnel over other actors, such as directors and organ donation coordinators. Health personnel's attitudes toward deceased organ donation was the most examined topic. In conclusion, a growing quantitative literature analyzes the perspective of physicians and nurses with regard to deceased organ donation and transplantation.

A narrative review of the empirical evidence on public attitudes on brain death and vital organ transplantation: the need for better data to inform policy

Vital organ transplantation is premised on 'the dead donor rule': donors must be declared dead according to medical and legal criteria prior to donation. However, it is controversial whether individuals diagnosed as 'brain dead' are really dead in accordance with the established biological conception of death-the irreversible cessation of the functioning of the organism as a whole. A basic understanding of brain death is also relevant for giving valid, informed consent to serve as an organ donor. There is therefore a need for reliable empirical data on public understanding of brain death and vital organ transplantation. We conducted a review of the empirical literature that identified 43 articles with approximately 18,603 study participants. These data demonstrate that participants generally do not understand three key issues: (1) uncontested biological facts about brain death, (2) the legal status of brain death and (3) that organs are procured from brain dead patients while their hearts are still beating and before their removal from ventilators. These data suggest that, despite scholarly claims of widespread public support for organ donation from brain dead patients, the existing data on public attitudes regarding brain death and organ transplantation reflect substantial public confusion. Our review raises questions about the validity of consent for vital organ transplantation and suggests that existing data are of little assistance in developing policy proposals for organ transplantation from brain dead patients. New approaches to rigorous empirical research with educational components and evaluations of understanding are urgently needed.

Non-therapeutic intensive care for organ donation

Background and Purpose:

Providing non-therapeutic intensive care for some patients in hopeless condition after cerebrovascular stroke in order to protect their organs for possible post-mortem organ donation after brain death is an effective but ethically tricky strategy to increase organ grafting. Finding out the feelings and opinion of the involved healthcare professionals and assessing the training needs before implementing such a strategy is critical to avoid backlash even in a presumed consent system.

Participants and methods:

A single-centre opinion survey of healthcare professionals was conducted in 2013 in the potentially involved wards of a French University Hospital: the Neurosurgical, Surgical and Medical Intensive Care Units, the Stroke Unit and the Emergency Department. A questionnaire with multiple-choice questions and one open-ended question was made available in the different wards between February and May 2013.

Ethical considerations:

The project was approved by the board of the Lorraine University Diploma in Medical Ethics.

Results:

Of a total of 340 healthcare professionals, 51% filled the form. Only 21.8% received a specific education on brain death, and only 18% on potential donor’s family approach and support. Most healthcare professionals (93%) think that non-therapeutic intensive care is the continuity of patient’s care. But more than 75% of respondents think that the advance patient’s consent and the consent of the family must be obtained despite the presumed consent rule regarding post-mortem organ donation in France.

Conclusion:

The acceptance by healthcare professionals of non-therapeutic intensive care for brain death organ donation seems fairly good, despite a suboptimal education regarding brain death, non-therapeutic intensive care and families’ support. But they ask to require previously expressed patient’s consent and family’s approval. So, it seems that non-therapeutic intensive care should only remain an ethically sound mean of empowerment of organ donors and their families to make post-mortem donation happen as a full respect of individual autonomy.

Implementation intentions as a strategy to increase the notification rate of potential ocular tissue donors by nurses: a clustered randomized trial in hospital settings

Aim. The purpose of this study is to evaluate the impact, among nurses in hospital settings, of a questionnaire-based implementation intentions intervention on notification of potential ocular tissue donors to donation stakeholders. Methods. This randomized intervention was clustered at the level of hospital departments with two study arms: questionnaire-based implementation intentions intervention and control. In the intervention group, nurses were asked to plan specific actions if faced with a number of barriers when reporting potential ocular donors. The primary outcome was the potential ocular tissue donors' notification rate before and after the intervention. Analysis was based on a generalized linear model with an identity link and a binomial distribution. Results. We compared outcomes in 26 departments from 5 hospitals, 13 departments per condition. The implementation intentions intervention did not significantly increase the notification rate of ocular tissue donors (intervention: 23.1% versus control: 21.1%; χ (2) = 1.14, 2; P = 0.56). Conclusion. A single and brief implementation intentions intervention among nurses did not modify the notification rate of potential ocular tissue donors to donation stakeholders. Low exposure to the intervention was a major challenge in this study. Further studies should carefully consider a multicomponent intervention to increase exposure to this type of intervention.

Organ and tissue donation in clinical settings: a systematic review of the impact of interventions aimed at health professionals

In countries where presumed consent for organ donation does not apply, health professionals (HP) are key players for identifying donors and obtaining their consent. This systematic review was designed to verify the efficacy of interventions aimed at HPs to promote organ and tissue donation in clinical settings. CINAHL (1982 to 2012), COCHRANE LIBRARY, EMBASE (1974 to 2012), MEDLINE (1966 to 2012), PsycINFO (1960 to 2012), and ProQuest Dissertations and Theses were searched for papers published in French or English until September 2012. Studies were considered if they met the following criteria: aimed at improving HPs’ practices regarding the donation process or at increasing donation rates; HPs working in clinical settings; and interventions with a control group or pre-post assessments. Intervention behavioral change techniques were analyzed using a validated taxonomy. A risk ratio was computed for each study having a control group. A total of 15 studies were identified, of which only 5 had a control group. Interventions were either educational, organizational or a combination of both, and had a weak theoretical basis. The most common behavior change technique was providing instruction. Two sets of interventions showed a significant risk ratio. However, most studies did not report the information needed to compute their efficacy. Therefore, interventions aimed at improving the donation process or at increasing donation rates should be based on sound theoretical frameworks. They would benefit from more rigorous evaluation methods to ensure good knowledge translation and appropriate organizational decisions to improve professional practices.

On noncongruence between the concept and determination of death

The debate about exactly when a person dies can benefit from distinguishing the strict biological concept of death from the medical standards for determining death.

Donation after circulatory death: current status

PURPOSE OF REVIEW

Donor shortage has forced transplant teams to explore new methods to increase the potential donor pool. Donation after circulatory death (DCD) has opened new perspectives and could be a valuable option to expand the brain-dead donors. The purpose of this review is to provide an overview of current practice and to identify remaining questions related to ethical and medical issues that should be further addressed in the future.

RECENT FINDINGS

Recent findings demonstrate acceptable outcomes after DCD kidney and lung transplantation but inferior graft survival for liver transplantation. The impact and importance of the agonal phase following withdrawal of treatment in controlled DCD is increasingly recognized. Premortem interventions are currently under debate related to preservation strategies or comfort therapy. New preservation strategies using in-situ/in-vivo extracorporeal membrane oxygenation or ex-vivo machine perfusion have large potential in the future. Finally, organizations and institutions are reporting more uniform guidelines related to declaration of death and DCD organ procurement.

SUMMARY

DCD donation has regained much attention during the last decade and is now part of standard clinical practice albeit this type of donation should not be regarded as an equally acceptable alternative for donation after brain death. It will be important to further explore the potential of DCD, to monitor the long-term outcomes and to further optimize the quality of these grafts. Development and implementation of uniform guidelines will be necessary to guarantee the clinical use of these donor pools.

Attitudes of young adults from the UK towards organ donation and transplantation

Background

This study examines the attitudes of young British adults towards donating their own organs and those of their family members.

Methods

An opportunity sample of 119 participants (65 female) completed an attitude questionnaire.

Results

Most participants were in favour of donation though substantially fewer had signed up to the organ donation register. A minority of participants was aware of the proposed opt-out system for donation.

Conclusions

The results from this study corroborate and extend previous work in that more participants were prepared to receive an organ than donate one. Knowing someone who had donated an organ was associated with a more positive attitude towards donation. Implications for policy are discussed.

Controversies in defining and determining death in critical care

Circulatory-respiratory or brain tests are widely accepted for definition and determination of death, but have several controversial issues. Both determinations have been stimulated by organ donation, but must be valid independently of this process. Current controversies in brain death include whether the definition is conceptually coherent, whether the whole-brain or brainstem criterion is correct, whether one neurological examination or two should be required, and when to conduct the examination following therapeutic hypothermia. Controversies about the circulatory determination of death include the minimum duration of asystole that is sufficient for death to be declared, and whether the distinction between permanent and irreversible cessation of circulatory functioning is important. In addition, the goal of organ donation raises issues such as the optimal way to time and conduct the request conversation with family members of the patient, and whether the Dead Donor Rule should be abandoned.
