Organ Donation Authorization After Brain Death Among Patients Admitted to PICUs in the United States, 2009-2018

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.

Racial disparities across multiple stages of the deceased organ donation process

Pervasive structural violence causes higher organ failure rates among Black Americans and an excess of Black potential deceased organ donors. Underuse of Black donors would exacerbate organ shortages that disproportionately harm Black transplant candidates. This study investigates racial differences in transit between distinct donation steps among 132 968 potential donors across 557 hospitals and 6 organ procurement organizations (OPOs) from 2015 through 2021. Multilevel multistate modeling with patient covariates and OPO random effects shows adjusted likelihoods (95% confidence interval) of non-Black versus Black patients transitioning from OPO referral to approach of 1.39 (1.35, 1.44), approach to authorization: 1.64 (1.56, 1.72), authorization to procurement: 1.10 (1.04, 1.16), and procurement to transplant: 1.00 (0.95, 1.06). Overall organ utilization rates for Black, Latino, White, and other OPO referrals were 5.89%, 8.18%, 6.79%, and 5.24%, respectively. Adjusting for patient covariates and hospital and OPO random effects, multilevel logistic models estimated that compared with Black patients, Latino, White, and other patients had odds ratios of organ utilization of 1.81 (1.61, 2.03), 3.19 (2.91, 3.50), and 1.24 (1.05, 1.47), respectively. Nationwide in 2022, donor conversion disparities likely lost more than 1700 donors-two-thirds of whom would have been Black. Achieving racial equity for transplant candidates will require reducing racial disparities in organ donation.

Organ Dysfunction Among Children Meeting Brain Death Criteria: Implications for Organ Donation

OBJECTIVES

Over 70% of pediatric organ donors are declared deceased by brain death (BD) criteria. Patients with these devastating neurologic injuries often have accompanying multiple organ dysfunction. This study was performed to characterize organ dysfunction in children who met BD criteria and were able to donate their organs compared with those deemed medically ineligible.

DESIGN

Retrospective cohort study.

SETTING

PICU at a quaternary care children's hospital.

PATIENTS

Patients with International Classification of Diseases , 9th Edition codes corresponding to BD between 2012 and 2018 were included.

MEASUREMENTS AND MAIN RESULTS

Demographics, comorbidities, Pediatric Risk of Mortality (PRISM)-III, and injury mechanisms were derived from the medical record. Organ dysfunction was quantified by evaluating peak daily organ-specific variables. Fifty-eight patients, from newborn to 22 years old, were included with a median PRISM-III of 34 (interquartile range [IQR], 26-36), and all met criteria for multiple organ dysfunction syndrome (MODS). Thirty-four of 58 BD children (59%) donated at least one organ. Of the donors (not mutually exclusive proportions), 10 of 34 donated lungs, with a peak oxygenation index of 11 (IQR, 8-23); 24 of 34 donated their heart (with peak Vasoactive Inotrope Score 23 [IQR, 18-33]); 31 of 34 donated kidneys, of whom 16 of 31 (52%) had evidence of acute kidney injury; and 28 of 34 patients donated their liver, with peak alanine transferase (ALT) of 104 U/L (IQR, 44-268 U/L) and aspartate aminotransferase (AST) of 165 U/L (IQR, 94-434 U/L). Organ dysfunction was similar between heart and lung donors and respective medically ineligible nondonors. Those deemed medically ineligible to donate their liver had higher peak ALT 1,518 U/L (IQR, 986-1,748 U/L) ( p = 0.01) and AST 2,200 U/L (IQR, 1,453-2,405 U/L) ( p = 0.01) compared with liver donors.

CONCLUSIONS

In our single-center experience, all children with BD had MODS, yet more than one-half were still able to donate organs. Future research should further evaluate transplant outcomes of dysfunctional organs prior to standardizing donation eligibility criteria.

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.
