Pediatric Donation After Circulatory Determination of Death: A Scoping Review

Neonatal organ donation: Retrospective audit into potential donation in a single neonatal unit

BACKGROUND

Research has shown that many babies who die in neonatal units could have been potential tissue and/or organ donors. Despite the existence of guidelines supporting its implementation, the incidence of neonatal donation remains rare in the United Kingdom.

AIM

The aim of this audit was to retrospectively determine potential eligibility for neonatal tissue and/or organ donation referral in infants who died in a single UK tertiary-level neonatal unit between 2012 and 2021. Cause of death and documentation of any discussions held regarding referral for donation were also explored.

STUDY DESIGN

An audit was undertaken to identify all neonatal deaths at a single tertiary-level NICU in London from 2012-2021. Infants who retrospectively could have been referred as potential tissue and/or organ donors were identified using current NHS Blood and Transplant inclusion and exclusion criteria.

RESULTS AND CONCLUSION

A significant missed potential for neonatal tissue and/or organ donation referrals was identified, which is likely not just limited to the unit audited. Causes of death were as expected for a tertiary level neonatal unit and centre for therapeutic cooling of babies born with hypoxic perinatal brain injuries. Only one documented conversation was found regarding neonatal donation.

RELEVANCE TO CLINICAL PRACTICE

To enable conversations regarding neonatal donation to become a routine part of end-of-life care discussions with families as appropriate, good links between neonatal healthcare professionals and Specialist Nurses in Organ Donation need to be established. This will facilitate the referral of all suitable neonates as potential donors and ensure that neonatal staff feel supported to care for babies identified as potential donors.

Pediatric Death After Withdrawal of Life-Sustaining Therapies: A Scoping Review

OBJECTIVES

Evaluate literature on the dying process in children after withdrawal of life sustaining measures (WLSM) in the PICU. We focused on the physiology of dying, prediction of time to death, impact of time to death, and uncertainty of the dying process on families, healthcare workers, and organ donation.

DATA SOURCES

MEDLINE, Embase, Cochrane Central Register of Controlled Trials, PsycINFO, CINAHL, and Web of Science.

STUDY SELECTION

We included studies that discussed the dying process after WLSM in the PICU, with no date or study type restrictions. We excluded studies focused exclusively on adult or neonatal populations, children outside the PICU, or on organ donation or adult/pediatric studies where pediatric data could not be isolated.

DATA EXTRACTION

Inductive qualitative content analysis was performed.

DATA SYNTHESIS

Six thousand two hundred twenty-five studies were screened and 24 included. Results were grouped into four categories: dying process, perspectives of healthcare professionals and family, WLSM and organ donation, and recommendations for future research. Few tools exist to predict time to death after WLSM in children. Most deaths after WLSM occur within 1 hour and during this process, healthcare providers must offer support to families regarding logistics, medications, and expectations. Providers describe the unpredictability of the dying process as emotionally challenging and stressful for family members and staff; however, no reports of families discussing the impact of time to death prediction were found. The unpredictability of death after WLSM makes families less likely to pursue donation. Future research priorities include developing death prediction tools of tools, provider and parental decision-making, and interventions to improve end-of-life care.

CONCLUSIONS

The dying process in children is poorly understood and understudied. This knowledge gap leaves families in a vulnerable position and the clinical team without the necessary tools to support patients, families, or themselves. Improving time to death prediction after WLSM may improve care provision and enable identification of potential organ donors.

Ethical Issues in Donation following Circulatory Death: A Scoping Review Examining Changes over Time from 1993 to 2022

Background: Ethical frameworks for organ donation following circulatory death (DCD) were established >20 years ago. However, considerable variation exists among these, indicating consensus has not been reached on all issues. Additionally, advances such as cardiac DCD transplants and normothermic regional perfusion (NRP) may have reignited old debates.Methods: We reviewed the English-language literature addressing ethical issues in DCD from 1993 to 2022, examining changes in frequency with which ethical principles and their sub-themes identified within each, were addressed.Results: Non-maleficence was the most frequently addressed principle (192 of 199 articles), as well as the most varied, with 9 subthemes (versus 2-4 within each of the other bioethical principles).Conclusions: There were several changes in the terminology used to refer to DCD over time, and substantial interest in cardiac DCD and NRP in recent publications, arising in 11 and 19 of the 30 publications from 2018 to 2022.

Autoresuscitation after circulatory arrest: an updated systematic review

PURPOSE

Current practice in organ donation after death determination by circulatory criteria (DCD) advises a five-minute observation period following circulatory arrest, monitoring for unassisted resumption of spontaneous circulation (i.e., autoresuscitation). In light of newer data, the objective of this updated systematic review was to determine whether a five-minute observation time was still adequate for death determination by circulatory criteria.

SOURCE

We searched four electronic databases from inception to 28 August 2021, for studies evaluating or describing autoresuscitation events after circulatory arrest. Citation screening and data abstraction were conducted independently and in duplicate. We assessed certainty in evidence using the GRADE framework.

PRINCIPAL FINDINGS

Eighteen new studies on autoresuscitation were identified, consisting of 14 case reports and four observational studies. Most studies evaluated adults (n = 15, 83%) and patients with unsuccessful resuscitation following cardiac arrest (n = 11, 61%). Overall, autoresuscitation was reported to occur between one and 20 min after circulatory arrest. Among all eligible studies identified by our reviews (n = 73), seven observational studies were identified. In observational studies of controlled withdrawal of life-sustaining measures with or without DCD (n = 6), 19 autoresuscitation events were reported in 1,049 patients (incidence 1.8%; 95% confidence interval, 1.1 to 2.8). All resumptions occurred within five minutes of circulatory arrest and all patients with autoresuscitation died.

CONCLUSION

A five-minute observation time is sufficient for controlled DCD (moderate certainty). An observation time greater than five minutes may be needed for uncontrolled DCD (low certainty). The findings of this systematic review will be incorporated into a Canadian guideline on death determination.

Potential of neonatal organ donation and outcome after transplantation

Organ transplantation is limited by access to suitable organs. Infant recipient waitlist mortality is increased due to the scarcity of size-matched organs. Neonatal organ donors have been proposed as an underutilized source of donor organs. However, the literature on the actual prevalence and outcome of neonatal organ donation and transplantation is fragmented and not well analyzed. This literature review aims to summarize the available literature on the potential of neonatal organ donation and to analyze published cases of neonatal organ transplantation. A systematic search of the Medline and Cochrane databases yielded 2964 articles, which were screened for eligibility. In total, 86 articles were considered eligible, of which 34 were included in the literature review: 8 articles describing the potential of neonatal organ donation programs, and 26 articles describing clinical transplantation. Current evidence suggests there is a large pool of potential neonatal organ donors. In contrast, the literature on neonatal organ donor utilization is sparse. However, case series of successful kidney, heart, liver, hepatocyte, and multivisceral transplantation using organs from neonatal donors are summarized. Although good posttransplant organ function was achieved, the use of neonatal organs is associated with increased risk of thrombosis in both kidney and liver transplantation. Neonatal organ donation is a promising alternative for expanding the current donor pool. Experience is limited, but reported patient and graft survival are acceptable and more research on the subject is warranted.

Implementation of a neonatal donation protocol in the neonatal intensive care unit: A single-center experience

BACKGROUND

Lack of specific protocols for neonatal donation contributes to the rarity of neonatal donors. In this study, we evaluate the impact of the implementation of a neonatal donation protocol in our NICU.

METHODS

In this single-center study, we conducted a retrospective chart review of neonatal deaths in our NICU from January 2013 to January 2022. The study was divided into two periods: before and after the implementation of a neonatal donation protocol. The referral rates of potential neonatal donors to the OPO in the two periods were compared using the chi-square test. A p value < .05 was considered statistically significant.

RESULTS

Sixty-four infants were reviewed. Seven (10.9%) met the inclusion criteria for potential neonatal donors after DCC. The referral rate of potential neonatal donors increased from 2.5% to 16.7% after the implementation of this protocol (p = .041), and one infant (4.1%) became an effective heart-valve donor.

CONCLUSION

The implementation of a local neonatal donation protocol could have contributed to increase the referral rate of potential neonatal donors in our NICU. Following the implementation of a local neonatal donation protocol, we were able to perform a heart-valve donation for the first time in our unit.

Paediatric death after withdrawal of life-sustaining therapies: a scoping review protocol

INTRODUCTION

The physiology of dying after withdrawal of life-sustaining measures (WLSM) is not well described in children. This lack of knowledge makes predicting the duration of the dying process difficult. For families, not knowing this process's duration interferes with planning of rituals related to dying, travel for distant relatives and emotional strain during the wait for death. Time-to-death also impacts end-of-life care and determines whether a child will be eligible for donation after circulatory determination of death. This scoping review will summarise the current literature about what is known about the dying process in children after WLSM in paediatric intensive care units (PICUs).

METHODS AND ANALYSIS

This review will use Joanna Briggs Institute methodology for scoping reviews. Databases searched will include Ovid MEDLINE, Ovid Embase, Cochrane Central Register of Controlled Trials via EBM Reviews Ovid, Ovid PsycINFO, CINAHL and Web of Science. Literature reporting on the physiology of dying process after WLSM, or tools that predict time of death in children after WLSM among children aged 0-18 years in PICUs worldwide will be considered. Literature describing the impact of prediction or timing of death after WLSM on families, healthcare workers and the organ donation process will also be included. Quantitative and qualitative studies will be evaluated. Two independent reviewers will screen references by title and abstract, and then by full text, and complete data extraction and analysis.

ETHICS AND DISSEMINATION

The review uses published data and does not require ethics review. Review results will be published in a peer-reviewed scientific journal.

Predicting Time to Death After Withdrawal of Life-Sustaining Treatment in Children

Accurately predicting time to death after withdrawal of life-sustaining treatment is valuable for family counseling and for identifying candidates for organ donation after cardiac death. This topic has been well studied in adults, but literature is scant in pediatrics. The purpose of this report is to assess the performance and clinical utility of the available tools for predicting time to death after treatment withdrawal in children.

Healthcare Professionals’ Understandings of the Definition and Determination of Death: A Scoping Review

Background.

During the 1950s, advances in critical care, and organ transplantation altered the relationship between organ failure and death. There has since been a shift away from traditional cardiocirculatory based to brain-based criteria of death, with resulting academic controversy, despite the practice being largely accepted worldwide. Our objective is to develop a comprehensive description of the current understandings of healthcare professionals regarding the meaning, definition, and determination of death.

Methods.

Online databases were used to identify papers published from 2003 to 2020. Additional sources were searched for conference proceedings and theses. Two reviewers screened papers using predefined inclusion and exclusion criteria. Complementary searches and review of reference lists complemented the final study selection. A data extraction instrument was developed to iteratively chart the results of the review. A qualitative approach was conducted to thematically analyze the data.

Results.

Seven thousand four hundred twenty-eight references were identified. In total, 75 papers met the inclusion criteria. Fourteen additional papers were added from complementary searches. Most were narratives (35%), quantitative investigations (21%), and reviews (18%). Identified themes included: (1) the historical evolution of brain death (BD), (2) persistent controversies about BD and death determination, (3) wide variability in healthcare professionals’ knowledge and attitudes, (4) critical need for BD determination revision.

Conclusions.

We concluded that although BD is widely accepted, there exists variation in healthcare providers’ understanding of its conceptual basis. Death determination remains a divisive issue among scholars. This review identified a need for increased opportunities for formal training on BD among healthcare providers.

Eligible neonatal donors after circulatory determination of death (Maastricht type III): A national survey of level III NICUs

BACKGROUND

Organ donation continues to increase worldwide, but in general paediatric patients remain less likely to receive a transplant. The inclusion of neonates as donors after cDCD should be considered in an effort to increase donation rates.

METHODS

The survey for a cross-sectional national study of potential cDCD neonatal donors (Maastricht type III) was sent to all 90 level III Spanish neonatal units to explore: 1) protocols, education, and specific opinions on donation and 2) potential cDCD that could have been eligible over a 2-year period (2014-2015).

RESULTS

Forty-five centers (50%) completed the survey, and 38/45 gave information about potential eligible donors. In 16% of the centers specific protocols on neonatal donation exist. All hospitals demanded more specific training, and 65% noted that the donation process could be a problem in the family's dismissal of the child. During the study period 46 805 neonates were admitted in the 38 centers, and 625 neonates died. Ninety-five born at a gestational age ≥34 weeks and above 2000 gr died after an EoL decision, 38 (40%) and 13 (14%) of them due to neonatal encephalopathy and multiple congenital anomalies, respectively. There were 31 (33%) elegible infants who died in less than 120 min due to pathologies that did not contraindicate donation.

CONCLUSIONS

Neonatal cDCD could help to reduce the gap between the supply of and demand for organs according to the potentially eligible patients emerging from this study. Training in EoL and donation processes should be provided to healthcare professionals.

Ethical considerations in the use of pre-mortem interventions to support deceased organ donation: A scoping review

AIM

Pre-mortem interventions (PMIs) are performed on patients before the determination of death in order to preserve or enhance the possibility of organ donation. These interventions can be ethically controversial, and we thus undertook a scoping review of the ethical issues surrounding diverse PMIs.

METHODS

Using modified scoping review methods, we executed a search strategy created by an information specialist. Screening and iterative coding of each article was done by two researchers using qualitative thematic analysis, and narrative summaries of coded themes were presented.

RESULTS

We identified and screened 5365 references and coded 196 peer-reviewed publications. The most frequently cited issues were related to possible harms to the patient who is a potential donor, and legitimacy of consent. The most controversial issue was that PMIs may place patients at risk for physical harm, yet benefit is accrued mainly to recipients. Some authors argued that lack of direct medical benefit to the still living patient precluded valid consent from surrogate decision makers (SDMs), while many stated that some medical risk could be approved by SDMs if it aligns with non-medical benefits valued by the patient.

CONCLUSION

PMIs require consensus that benefit includes concepts beyond medical benefit to the patient who is a potential donor. Informed consent must be confirmed for each PMI and not assumed to be part of general consent for donation. Risk must be proportionate to the potential benefit and newly proposed interventions should be reviewed carefully for medical efficacy and potential risks.

Is donation after circulatory determination of death feasible for pediatric patients in italy?

To determine the potential effect of a donation after cardiac death active program on the number of organ donors in a Italian Pediatric Intensive Care Unit (PICU). We conducted a retrospective study of all deaths in PICU of an academic Children Hospital between 2012 and 2020, tracing the organ donation activity. Patients were categorized as brain deaths, deaths despite maximal resuscitation, and deaths after withdrawal or limitation of life support. Patient demographics, premortem physiology, end-of-life circumstances, and functional warm ischemia time were recorded. Eligible donors after cardiac death were identified by the absence of medical contraindication and functional warm ischemia time <60 minutes. Of 124 deaths that occurred during the study period, 34 met criteria for brain death, 23 were potential donors, and 13 became actual donors. Of the remaining 90 patients that met criteria for cardiac death, 66 died despite maximal resuscitation, 24 died after withdrawal or limitation of care and between them 13 were identified as theoretically eligible DCD donors. Of these, 5 patients had a functional warm ischemia time of <1 hour and were potential candidates for DCD of 10 kidneys and 2 lungs. Even if few children could have been eligible for DCD in the study period, an active program could have been able to increase the number of potential organ donors by 20% in the last eight years at our institution. DCD deserves to be explored in Italy as a new option for children.

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.

Machine Learning to Predict Cardiac Death Within 1 Hour After Terminal Extubation

OBJECTIVES

Accurate prediction of time to death after withdrawal of life-sustaining therapies may improve counseling for families and help identify candidates for organ donation after cardiac death. The study objectives were to: 1) train a long short-term memory model to predict cardiac death within 1 hour after terminal extubation, 2) calculate the positive predictive value of the model and the number needed to alert among potential organ donors, and 3) examine associations between time to cardiac death and the patient's characteristics and physiologic variables using Cox regression.

DESIGN

Retrospective cohort study.

SETTING

PICU and cardiothoracic ICU in a tertiary-care academic children's hospital.

PATIENTS

Patients 0-21 years old who died after terminal extubation from 2011 to 2018 (n = 237).

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

The median time to death for the cohort was 0.3 hours after terminal extubation (interquartile range, 0.16-1.6 hr); 70% of patients died within 1 hour. The long short-term memory model had an area under the receiver operating characteristic curve of 0.85 and a positive predictive value of 0.81 at a sensitivity of 94% when predicting death within 1 hour of terminal extubation. About 39% of patients who died within 1 hour met organ procurement and transplantation network criteria for liver and kidney donors. The long short-term memory identified 93% of potential organ donors with a number needed to alert of 1.08, meaning that 13 of 14 prepared operating rooms would have yielded a viable organ. A Cox proportional hazard model identified independent predictors of shorter time to death including low Glasgow Coma Score, high Pao2-to-Fio2 ratio, low-pulse oximetry, and low serum bicarbonate.

CONCLUSIONS

Our long short-term memory model accurately predicted whether a child will die within 1 hour of terminal extubation and may improve counseling for families. Our model can identify potential candidates for donation after cardiac death while minimizing unnecessarily prepared operating rooms.

Resumption of Cardiac Activity after Withdrawal of Life-Sustaining Measures

BACKGROUND

The minimum duration of pulselessness required before organ donation after circulatory determination of death has not been well studied.

METHODS

We conducted a prospective observational study of the incidence and timing of resumption of cardiac electrical and pulsatile activity in adults who died after planned withdrawal of life-sustaining measures in 20 intensive care units in three countries. Patients were intended to be monitored for 30 minutes after determination of death. Clinicians at the bedside reported resumption of cardiac activity prospectively. Continuous blood-pressure and electrocardiographic (ECG) waveforms were recorded and reviewed retrospectively to confirm bedside observations and to determine whether there were additional instances of resumption of cardiac activity.

RESULTS

A total of 1999 patients were screened, and 631 were included in the study. Clinically reported resumption of cardiac activity, respiratory movement, or both that was confirmed by waveform analysis occurred in 5 patients (1%). Retrospective analysis of ECG and blood-pressure waveforms from 480 patients identified 67 instances (14%) with resumption of cardiac activity after a period of pulselessness, including the 5 reported by bedside clinicians. The longest duration after pulselessness before resumption of cardiac activity was 4 minutes 20 seconds. The last QRS complex coincided with the last arterial pulse in 19% of the patients.

CONCLUSIONS

After withdrawal of life-sustaining measures, transient resumption of at least one cycle of cardiac activity after pulselessness occurred in 14% of patients according to retrospective analysis of waveforms; only 1% of such resumptions were identified at the bedside. These events occurred within 4 minutes 20 seconds after a period of pulselessness. (Funded by the Canadian Institutes for Health Research and others.).

Potential Heart, Liver, and Kidney Donation after Circulatory Determination of Death in a Neonatal Intensive Care Unit

BACKGROUND

Pediatric organ donation after circulatory determination of death (DCD) has increased in recent years; however, there are few data reporting the number of neonatal potential DCD organ donors and no Canadian-specific reports.

OBJECTIVE

The main objective of this study was to estimate the number of patients who may have become actual DCD organ donors from a single, tertiary neonatal intensive care unit (NICU) over 5 years.

METHODS

We reviewed all medical charts of newborns ≥2.5 kg, who died in our center's NICU from January 2013 to December 2017. We determined how many could have become actual organ donors after brain death (DBD) or DCD based on 3 sets of organ-specific eligibility criteria defined as conservative, standard, and liberal.

RESULTS

Of the 39 deceased patients, none met the criteria for DBD. Twenty-nine (75%) died after the withdrawal of life-sustaining therapies. According to the conservative criteria, 1 patient would have been eligible for kidneys and liver donation. Three patients met standard criteria for kidneys and 1 for liver. Eight patients would have been eligible donors for kidneys, 7 for liver, and 2 for heart according to liberal criteria. Only 2 patients were evaluated for DCD, and no organ donation was performed.

CONCLUSIONS

While uncommon, we identified potential DCD organ donors in the NICU population for kidney, heart, and liver transplants. The substantial variability in the number of potential donors depending on the selected eligibility criteria emphasizes the need for a standardized definition adapted to local capacities.

Organ donation in the US and Europe: The supply vs demand imbalance

Organ donation and transplantation remain the best and most cost-effective clinical solution for end-stage organ failure. Several agencies across the US and Europe provide legislative, regulatory, and humanitarian services to generate smoother applications in all transplantation processes and donor-recipient relationships. US and European statistics present nine types of grafts, with kidneys being the most transplanted organ worldwide. However, organ shortage, religion, underrepresented minority groups, difficulties in obtaining consent, lack of understanding, and general ethical concerns present challenging barriers to organ donation, reflecting the complexity of graft procurement and allocation. Breaking down these barriers to reduce the organ-supply imbalance requires an appropriate multifaceted approach. Some of the key areas include increasing the potential donor pool and consent rates, apt organ allocation, and improving organ health. Additionally, suitable policies and standardized guidelines for both donors and recipients, alongside educational initiatives, are needed to ensure patient safety and global awareness. Looking forward, novel and effective research plans and initiatives are needed if we are to avoid a colossal supply-demand gap.

First pediatric organ donation after circulatory determination of death in Singapore: Facing challenges in the absence of a local practice guideline

Pediatric organ donation represents only a low proportion of overall organ donation in many parts of world, unable to match the needs for pediatric organ transplantation. Pediatric organ donation after circulatory determination of death (DCD) is increasingly explored in pediatric transplantation, as it increases the availability of organ grafts. A 6-year-old Caucasian boy with a history of arteriovenous malformation presented with a catastrophic intracranial bleed, resulting in severe brainstem dysfunction despite maximal medical and surgical measures. He did not fulfill the criteria for brain death, which must be met for pediatric organ donation in Singapore. Due to parental request, his organs were donated after withdrawal of life support and determination of death by circulatory criteria. Pediatric organ DCD poses many challenges in the pediatric population, especially in the absence of a local practice guideline. We present the first case of a pediatric organ DCD that has occurred in Singapore. Further work is needed, particularly in establishing a national policy for pediatric organ DCD and increasing overall awareness and acceptance toward pediatric organ donations.

Patient and provider factors impacting referral for neonatal organ donation

BACKGROUND

As determination of brain death is infrequent in neonates, the AAP endorses donation after circulatory determination of death as an acceptable alternative. Despite this recommendation, neonatal organ donation is infrequent. Timely referral to OPOs is a vital first step in the organ donation process. The aim of this study was to identify patient and provider factors impacting timely referral for neonatal organ donation.

METHODS

Medical records were reviewed for deaths occurring in a Level IV NICU from 2007 to 2017. Clinical and demographic factors, provider type, timing of OPO referral (before or after death), and outcome were assessed. Bivariate and multivariable logistic regression models were utilized to identify predictors of OPO referral characteristics.

RESULTS

Between 2007 and 2017, 329 deaths occurred in the NICU or delivery room. Of the 265 infants meeting inclusion criteria, 96% had late referrals (after death) and were declined for organ donation. Frequency of timely referrals (before death) improved when OPO contact was by an attending neonatologist, when withdrawal of life support was planned, and with increasing birthweight, gestational age, and PMA. Factors associated with decreased OPO referral included male sex, lower weight at death, earlier PMA, and deaths occurring while receiving maximal intensive care support. No organs or tissues were donated.

CONCLUSIONS

This study is the first to report NICU referral patterns for organ donation. We found that timely provider referral of neonates to the OPO was rare. Exploration of provider knowledge will guide future educational interventions aimed to improve the referral process.

Exploring nurses' knowledge, attitudes and feelings towards organ and tissue donation after circulatory death within the paediatric intensive care setting in the United Kingdom: A qualitative content analysis study

OBJECTIVE

This study explored nurses' knowledge, attitudes and feelings towards donation after circulatory death identifying these domains as barriers and facilitators to nurses effectively undertaking their role in the donation after circulatory death donation process.

DESIGN

A single-phase qualitative study design.

SETTING

One paediatric cardiac intensive care unit in a tertiary paediatric hospital in England.

METHODS

Data was collected from eight paediatric cardiac intensive care nurses using semi-structured face to face or telephone interviews facilitated by a clinical vignette. Qualitative content analysis was undertaken adopting both inductive and deductive lenses.

KEY FINDINGS

Three categories were deductively generated within which eleven inductively generated themes were situated. Barriers included: knowledge deficits of both process and resources; assumptions about parental views and reluctance to facilitate sensitive discussions, facilitators included positive attitudes toward donation aligned with a strong professional ethos and family-centred values.

CONCLUSIONS

The paper identifies barriers to the donation after circulatory death process including nurses feeling unprepared for their role, anxiety over family approach and communication methods and support. Highlighted is the need for specific educational interventions, appropriate resources and development of paediatric focussed policy to guide practice. Facilitators to donation include timely, sensitive and appropriate family discussions, trusting nurse-family relationships and improved public awareness.

Development of a multinational registry of pediatric deceased organ donation activity

BACKGROUND

There are no currently agreed upon international standards for reporting of pediatric deceased organ donation activity. This leads to difficulty in comparisons between jurisdictions for both researchers and policy stakeholders. The goal of this project was to develop and test a standardized registry for pediatric deceased donation activity.

METHODS

Four countries (Canada, Spain, USA, and the UK) with geographical and practice diversity were approached to participate. Iterative exchanges were used to create data fields and definitions that were acceptable to all participants. Data from 2011 to 2015 (inclusive) were requested from national health databases and analyzed on a secure, web-based survey platform.

RESULTS

Data were obtained from three of the four countries (Canada unable to provide). Total pediatric donation rates were stable over the 5-year period, but with variation between countries. pDCD rates were the most variable, representing 32.2% of total pediatric donation in the UK, 14.4% in the United States, and 2.6% in Spain during the studied period. Most organs from pediatric donors were allocated to adult recipients, though the rates of allocation of pediatric kidneys to pediatric recipients ranged from 7% in the United States to 40% in Spain.

DISCUSSION

In this limited cohort of three countries, we demonstrated substantial variation in pediatric donation rates and practice. These data highlight opportunities for practice improvement such as the development of rigorous clinical practice guidelines. Future development of this registry will seek to engage more countries, and address barriers that prevented full participation of approached jurisdictions.

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.

GRADEing the un-GRADE-able: a description of challenges in applying GRADE methods to the ethical and implementation questions of pediatric organ donation guidelines

Good practice statements (GPSs) have been proposed by the GRADE working group as a way of avoiding the inappropriate characterization of evidence as low quality in support of strong recommendations justified by indirect evidence. This commentary examines how the GPS methodology was applied to the development of a recent guideline for pediatric deceased donation after circulatory determined death. This guideline was informed by a broad body of indirect literature and addressed a variety of social, legal, and ethical questions in addition to several implementation issues. While the resulting document contained a vast majority of GPS (63 as opposed to seven actionable GRADEd recommendations), we maintain that this application was appropriate to develop recommendations within the GRADE framework. This commentary explores how GPS may be applied in this context and explores whether a new classification of recommendations focused on these types of issues may be appropriate.

Literature overview highlights lack of paediatric donation protocols but identifies common themes that could guide their development

AIM

Paediatric donation is a unique and extremely sensitive process that requires specific knowledge and competencies. Most countries use protocols for organ and tissue donation to ensure optimal care for the donor and family, but these mainly focus on adults. However, the donation process for children differs from adults in many ways. An overview of the literature was performed to identify protocols for the paediatric population.

METHODS

PubMed, Web of Science, EMBASE and the Internet were searched up to March 2016 for papers or other sources in English related to specific organ and tissue donation protocols for children and neonates. This comprised title, abstract and then full-text screening of relevant data.

RESULTS

We included 12 papers and two electronic sources that were mainly from North America and Europe. Most discussed donations after cardiac death. The recurring themes included identifying potential donors, approaching parents, palliative care and collaboration with organ procurement organisations. Most papers called for paediatric donation policies to be standardised.

CONCLUSION

Scientific publications in English on paediatric donation protocols are very scarce. No comprehensive paediatric donation protocol was found. We identified several recurring themes in the literature that could be used to develop such protocols.

The path to paediatric donation after circulatory determination of death guidelines

Recently, Canada became the first country to publish paediatric specific guidelines for the practice of donation after circulatory death (pDCD). These guidelines, endorsed by the Canadian Paediatric Society, were created in response to the fact that pDCD in Canada was largely undeveloped even in tertiary care centres, and no national guidelines addressed the practice in children. This article explains what pDCD is and how these recommendations were developed.

Canadian Guidelines for Controlled Pediatric Donation After Circulatory Determination of Death-Summary Report

OBJECTIVES

Create trustworthy, rigorous, national clinical practice guidelines for the practice of pediatric donation after circulatory determination of death in Canada.

METHODS

We followed a process of clinical practice guideline development based on World Health Organization and Canadian Medical Association methods. This included application of Grading of Recommendations Assessment, Development, and Evaluation methodology. Questions requiring recommendations were generated based on 1) 2006 Canadian donation after circulatory determination of death guidelines (not pediatric specific), 2) a multidisciplinary symposium of national and international pediatric donation after circulatory determination of death leaders, and 3) a scoping review of the pediatric donation after circulatory determination of death literature. Input from these sources drove drafting of actionable questions and Good Practice Statements, as defined by the Grading of Recommendations Assessment, Development, and Evaluation group. We performed additional literature reviews for all actionable questions. Evidence was assessed for quality using Grading of Recommendations Assessment, Development, and Evaluation and then formulated into evidence profiles that informed recommendations through the evidence-to-decision framework. Recommendations were revised through consensus among members of seven topic-specific working groups and finalized during meetings of working group leads and the planning committee. External review was provided by pediatric, critical care, and critical care nursing professional societies and patient partners.

RESULTS

We generated 63 Good Practice Statements and seven Grading of Recommendations Assessment, Development, and Evaluation recommendations covering 1) ethics, consent, and withdrawal of life-sustaining therapy, 2) eligibility, 3) withdrawal of life-sustaining therapy practices, 4) ante and postmortem interventions, 5) death determination, 6) neonatal pediatric donation after circulatory determination of death, 7) cardiac and innovative pediatric donation after circulatory determination of death, and 8) implementation. For brevity, 48 Good Practice Statement and truncated justification are included in this summary report. The remaining recommendations, detailed methodology, full Grading of Recommendations Assessment, Development, and Evaluation tables, and expanded justifications are available in the full text report.

CONCLUSIONS

This process showed that rigorous, transparent clinical practice guideline development is possible in the domain of pediatric deceased donation. Application of these recommendations will increase access to pediatric donation after circulatory determination of death across Canada and may serve as a model for future clinical practice guideline development in deceased donation.

[Bioethics in end-of-life decisions in neonatology: Unresolved issues]

This document is the result of previous work carried out by different expert groups and submitted to multidisciplinary debate at a Conference about controversial, deficient, or new aspects in the field of neonatal palliative care, such as: 1) the deliberative decision-making process, 2) hospital and domiciliary palliative care, 3) donation after controlled cardiac death, and 4) moral stress in professionals. The most relevant conclusions were: the need to instruct professionals in bioethics and in the deliberative method to facilitate thorough and reasonable decision-making; the lack of development in the field of perinatal palliative care and domiciliary palliative care in hospitals that attend newborns; the need to provide neonatal units with resources that help train professionals in communication skills and in the management of moral distress, as well as delineate operational procedure and guidelines for neonatal organ donation.
