COVID-19 test result reporting for deceased donors: Emergent policies, logistical challenges, and future directions.

The coronavirus disease 2019 (COVID-19) pandemic poses unprecedented challenges to the transplant community, including organ procurement organizations (OPOs), transplant centers, regulatory agencies, and recipient candidates. Access to timely, accurate information on the status of deceased donor viral infection is essential in determining organ acceptance. The Organ Procurement and Transplantation Network expeditiously added fields to collect these data; however, use of the data collection fields was not uniform nationally. Standardized, field-defined data capture and reporting are vital to ensure optimal organ utilization during this pandemic, and to prepare the community for subsequent challenges.

Variation in use of procurement biopsies and its implications for discard of deceased donor kidneys recovered for transplantation.

The use of procurement biopsies in deceased donor kidney acceptance is controversial. We analyzed Scientific Registry of Transplant Recipients data (n = 59 328 allografts, 2014-2018) to describe biopsy practices across US organ procurement organizations (OPOs) and examine relationships with discards, using hierarchical modeling to account for OPO and donor factors. Median odds ratios (MORs) provide the median of the odds that allografts with identical reported traits would be biopsied or discarded from 2 randomly drawn OPOs. Biopsies were obtained for 52.7% of kidneys. Biopsy use rose in a graded manner with kidney donor profile index (KDPI). Biopsy rates differed significantly among OPOs (22.8% to 77.5%), even after adjustment for KDPI and other donor factors. Discard rates also varied from 6.6% to 32.1% across OPOs. After adjustment for donor factors and OPO, biopsy was associated with more than 3 times the likelihood of discard (adjusted odds ratio [95%LCL aOR95%UCL ], 3.29 3.513.76 ). This association was most pronounced for low-risk (KDPI <20) kidneys (aOR, 5.45 6.477.69 ), with minimal impact at KDPI >85 (aOR, 0.88 1.151.51 ). Adjusted MORs for kidney discard and biopsy were greatest for low-risk kidneys. Reducing the rate of unnecessary biopsy and improving the accuracy of histologic assessments in higher KDPI organs may help reduce graft discard rates.

Deceased Donor Procurement Biopsy Practices, Interpretation, and Histology-Based Decision-Making: A Survey of US Kidney Transplant Centers.

Introduction: The utility of kidney procurement biopsies is controversial. Understanding the current landscape of how clinicians obtain and use biopsies in organ evaluation may help inform consensus-building efforts. Methods: An electronic survey was distributed to clinicians at US kidney transplant programs (April 22, 2021-June 30, 2021) to evaluate donor biopsy indications, frequency, processing and interpretation, and impact of findings on practices. Results: Responses from staff involved in organ acceptance (73% surgeons, 20% nephrologists, 6% coordinators) at 95 transplant centers were analyzed, representing 40% of US transplant centers and 50% of recent deceased donor kidney transplant volume. More than a third of centers (35%) reported obtaining procurement biopsies on most-to-all kidneys. Most clinicians decided when to biopsy jointly with the Organ Procurement Organization (OPO) (82%) based on formal criteria for the decision (72%), although 41% reported having requested a biopsy outside of the criteria. Most respondents used a semiquantitative scoring system for interpretation (57%). Many respondents reported rarely or never having access to renal specialty pathologists (37%) or to telepathology (59%). Most respondents reported that a favorable biopsy result would encourage them to accept a "marginal" donor kidney (72%); nearly half (46%) indicated that an unfavorable biopsy result would lead to decline of a standard criteria kidney. Conclusion: Procurement biopsies are commonly used in organ acceptance decisions despite inconsistent access to experienced renal pathologists and heterogeneous approaches to criteria, scoring, and interpretation. Ongoing study and consensus building are needed to direct procurement biopsy practice toward increasing organ utilization and reducing allocation inefficiency.

Disparities in Deceased Organ Donor Research Authorization: Experience at One Organ Procurement Organization and Call for National Conversations.

INTRODUCTION: Research with deceased donor organs can provide an important platform for studying interventions to improve organ use and outcomes after authorization from the next-of-kin (NOK) or before death by the decedent (i.e., first-person authorization [FPA]). To date, information on authorization rates across donor subgroups is lacking. METHODS: We performed a retrospective chart review of all 690 deceased organ donors from January 2017 to December 2019 at a midsized Midwestern organ procurement organization (OPO). Multivariable logistic regression was used to assess associations between donor factors and research decline (adjusted odds ratio [aOR], 95% confidence interval [CI]). RESULTS: Electronic records for all 690 deceased donors were reviewed. Of these, 659 (95.5%) yielded at least one transplanted organ. Overall, research was declined in 10.8% of donations. Compared to White donors, research decline was higher for Black (16.0% vs. 8.9%; aOR, 1.87; 95% CI, 1.03-3.40; P = 0.04) and other non-White donors (24.0% vs. 8.9%; aOR, 4.21; 95% CI, 1.02-17.39; P = 0.05). Unadjusted research decline trended higher for Hispanic donors versus non-Hispanic donors (23.1% vs. 10.5%; P = 0.14). Compared to donors age <40 years, research decline trended higher for donors age ≥65 years (16.7% vs. 11.8%; aOR, 4.87; 95% CI, 1.12-21.05; P = 0.03), whereas research decline was 55% lower when donors provided FPA (7.3% vs 15.0%; aOR, 0.45; 95% CI, 0.27-0.76; P = 0.003). CONCLUSIONS: Deceased donor research authorization decline is higher for Black, other non-White, and older donors, but lower when the descendent provides FPA. Identification of disparities in research authorization may stimulate educational strategies to reduce barriers to scientific investigations directed at optimizing the outcomes of organ donation.
