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

Organ Donation in Canadian PICUs: A Cross-Sectional Survey, 2021-2022

OBJECTIVES

To understand contemporary pediatric organ donation programs in Canadian PICUs, including: policies and practices, data collection and reporting, and system and process barriers.

DESIGN

A cross-sectional survey carried out 2021-2022.

SETTING

Canadian PICUs affiliated with a donor physician network.

SUBJECTS

Pediatric intensivists identified as the donation program lead, or most knowledgeable about donation for their institution.

MEASUREMENTS AND MAIN RESULTS

A 19-item survey was developed through collaboration with stakeholders from the organ donation and transplantation community within Canada. Domains and items were generated and reduced iteratively during an in-person workshop. Pretesting and pilot testing were completed to ensure readability, flow, clinical sensibility, and construct validity. Fifteen of 16 (94%) invited Canadian PICUs from seven provinces completed the survey representing 88% (15/18) of all noncardiac Canadian PICUs. Surveys were completed between June 2021 and September 2022. All units support donation after death by neurologic criteria (DNC); 14 of 15 indicated donation policies were in place and 1 of 15 indicated no policy but the ability to facilitate donation. Thirteen of 15 units (87%) support donation after death by circulatory criteria (DCC) with policies in place, with 11 of 13 of these indicating routine support of donation opportunities. The majority (13/15) of units identified a donation champion. Of the 16 identified champions across these centers, 13 were physicians and were registered nurses or nurse practitioners. Eight of 13 units (62%) with donation champions had positions supported financially, of which 5 units came from the Organ Donation Organization and the other 3 came from the provincial health authority. Finally, only 3 of 15 PICU donation programs have a pediatric donation committee with family involvement. Variability exists in identification (including determination of death practices), referral, and approach for donation between units.

CONCLUSIONS

Although all Canadian PICUs support donation after DNC donation, and most support donation after DCC, variability exists in the identification, referral, and approach of potential donors. There is a notable lack of family involvement in pediatric donation programs. There are many opportunities for standardization of PICU donation programs which may result in improved rates of pediatric organ donation in Canada.

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.

Exploring Ethical Dimensions of Physician Involvement in Requests for Organ Donation in Pediatric Brain Death

Pediatric organ transplantation remains a life-saving therapy, with donated organs being absolutely scarce resources. Efforts to both increase pediatric organ donation authorization by families of children declared dead by neurologic criteria and mitigate perception of conflicts of interest have resulted in frequent exclusion of physicians from this process. This article provides of focused review of pediatric organ donation in the setting of brain death, explores the breadth of consequences of physician exclusion in donation authorization requests, and provides an ethical framework defending physician involvement in the organ donation process for this patient population.

Whole liver transplantation in children under 10 kg: How to minimize the high risks of a still challenging procedure

BACKGROUND

Whole liver transplantation in infants <10 kg is a rare procedure with moderate outcomes (67%-79% graft survival at 1 year) and high rates of vascular complications (hepatic artery thrombosis 5-26%).

METHODS

Retrospective single-center analysis of whole liver transplantation in infants <10 kg and systematic review of the literature focused on survival rates and surgical complications.

RESULTS

Between January 2005 and December 2020, 175 liver transplantations in 173 children were performed at our center. A total of 92 (53%) children weighed less than 10 kg; 19 (21%) of them underwent WLT and constitute the study population. Median age of the recipients was 10 months (21 days-24 months) and median body weight 6.5 (3.1-9.8) kg. Median age of the donors was 5 (1-84) months and median body weight 6.1 (4-21) kg. Median donor-to-recipient body weight ratio was 1.2 (range: 0.6-4.5). Postoperatively, neither hepatic artery nor portal vein thrombosis occurred. A biliary complication occurred in 4 cases: 1 bile leak (early), 3 anastomotic stenoses (1 delayed and 2 late), and 1 non-anastomotic stenosis (late). Patient survival rate at 1, 5, and 10 years was 100%, 92%, and 92%, respectively. Overall, death-censored graft survival after 1, 5, and 10 was 100%.

CONCLUSION

Our results are excellent in terms of complications and graft and patient survival. This involves not only high-end surgical performance but also close interdisciplinary perioperative cooperation based on strong standard operating procedures and mainly focused on fluid management, hemostasiology, and strict monitoring of vessel patency.

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.

Neonatal donation: are newborns too young to be recognized?

Neonatal organ and tissue donation is not common practice in the Netherlands. At the same time, there is a transplant waiting list for small size-matched organs and tissues. Multiple factors may contribute to low neonatal donation rates, including a lack of awareness of this option. This study provides insight into potential neonatal organ and tissue donors and reports on how many donors were actually reported to the procurement organization. We performed a retrospective analysis of the mortality database and medical records of two largest neonatal intensive care units (NICUs) in the Netherlands. This study reviewed records of neonates with a gestational age >37 weeks and weight >3000g who died in the period from January 1, 2005 through December 31, 2016. During the study period, 259 term-born neonates died in the two NICUs. In total, 132 neonates with general contra-indications for donation were excluded. The medical records of 127 neonates were examined for donation suitability. We identified five neonates with documented brain death who were not recognized as potential organ and/or tissue donors. Of the remaining neonates, 27 were found suitable for tissue donation. One potential tissue donor had been reported to the procurement organization. In three cases, the possibility of donation was brought up by parents.Conclusion: A low proportion (2%) of neonates who died in the NICUs were found suitable for organ donation, and a higher proportion (12%) were found suitable for tissue donation. We suggest that increased awareness concerning the possibility of neonatal donation would likely increase the identification of potential neonatal donors. What is Known: • There is an urgent need for very small organs and tissues from neonatal donors What is New: • A number of neonates who died in the NICU were suitable organ or/and tissue donors but were not recognized as donors. • Knowledge on neonatal donation possibilities is also important for proper counseling of parents who sometimes inquire for the possibility of organ and tissue donation.

Lack of knowledge and experience highlights the need for a clear paediatric organ and tissue donation protocol in the Netherlands

Aim

This study explored the attitudes of medical professionals to organ and tissue donation in paediatric intensive care units (PICUs) and neonatal intensive care units (NICUs) in the Netherlands. It also examined their compliance with the existing Dutch donation protocol and assessed whether a paediatric donation protocol was needed.

Methods

We invited 966 professionals working in all eight PICUs and the two largest NICUs to complete an online survey from December 2016 until April 2017.

Results

A quarter (25%) took part and they included PICU intensivists, neonatologists, nurses and other health and allied professionals. Most were female and nurses. More than half (54%) of the PICU respondents considered paediatric organ donation to be very important and 53% supported tissue donation. In contrast, only 22% of the NICU respondents believed that both neonatal organ and tissue donation were very important. Familiarity and compliance with the existing national donation protocol were low. PICU nurses had significantly less experience than PICU intensivists and felt less comfortable with the donation process. None of the NICU respondents had prior donation experience.

Conclusion

Paediatric intensive care units and NICU professionals lack specialised knowledge and experience on organ and tissue donation. A comprehensive and clear paediatric donation protocol is clearly needed.

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.
