Significant Improvements in the Practice Patterns of Adult Related Donor Care in US Transplantation Centers.

ABSTRACT: Recent investigations have found a higher incidence of adverse events associated with hematopoietic cell donation in related donors (RDs) who have morbidities that if present in an unrelated donor (UD) would preclude donation. In the UD setting, regulatory standards ensure independent assessment of donors, one of several crucial measures to safeguard donor health and safety. A survey conducted by the Center for International Blood and Marrow Transplant Research (CIBMTR) Donor Health and Safety Working Committee in 2007 reported a potential conflict of interest in >70% of US centers, where physicians had simultaneous responsibility for RDs and their recipients. Consequently, several international organizations have endeavored to improve practice through regulations and consensus recommendations. We hypothesized that the changes in the 2012 Foundation for the Accreditation of Cellular Therapy and the Joint Accreditation Committee-International Society for Cellular Therapy and European Society for Blood and Marrow Transplantation standards resulting from the CIBMTR study would have significantly impacted practice. Accordingly, we conducted a follow-up survey of US transplantation centers to assess practice changes since 2007, and to investigate additional areas where RD care was predicted to differ from UD care. A total of 73 centers (53%), performing 79% of RD transplantations in the United States, responded. Significant improvements were observed since the earlier survey; 62% centers now ensure separation of RD and recipient care (P < .0001). This study identifies several areas where RD management does not meet international donor care standards, however. Particular concerns include counseling and assessment of donors before HLA typing, with 61% centers first disclosing donor HLA results to an individual other than the donor, the use of unlicensed mobilization agents, and the absence of long-term donor follow-up. Recommendations for improvement are made.

Project description:Adult-to-adult living donors and recipients were studied to characterize patterns of liver growth and identify associated factors in a multicenter study. Three hundred and fifty donors and 353 recipients in the Adult-to-Adult Living Donor Liver Transplantation Cohort Study (A2ALL) receiving transplants between March 2003 and February 2010 were included. Potential predictors of 3-month liver volume included total and standard liver volumes (TLV and SLV), Model for End-Stage Liver Disease (MELD) score (in recipients), the remnant and graft size, remnant-to-donor and graft-to-recipient weight ratios (RDWR and GRWR), remnant/TLV, and graft/SLV. Among donors, 3-month absolute growth was 676 ± 251 g (mean ± SD), and percentage reconstitution was 80% ± 13%. Among recipients, GRWR was 1.3% ± 0.4% (8 < 0.8%). Graft weight was 60% ± 13% of SLV. Three-month absolute growth was 549 ± 267 g, and percentage reconstitution was 93% ± 18%. Predictors of greater 3-month liver volume included larger patient size (donors and recipients), larger graft volume (recipients), and larger TLV (donors). Donors with the smallest remnant/TLV ratios had larger than expected growth but also had higher postoperative bilirubin and international normalized ratio at 7 and 30 days. In a combined donor-recipient analysis, donors had smaller 3-month liver volumes than recipients adjusted for patient size, remnant or graft volume, and TLV or SLV (P = 0.004). Recipient graft failure in the first 90 days was predicted by poor graft function at day 7 (HR = 4.50, P = 0.001) but not by GRWR or graft fraction (P > 0.90 for each). Both donors and recipients had rapid yet incomplete restoration of tissue mass in the first 3 months, and this confirmed previous reports. Recipients achieved a greater percentage of expected total volume. Patient size and recipient graft volume significantly influenced 3-month volumes. Importantly, donor liver volume is a critical predictor of the rate of regeneration, and donor remnant fraction affects postresection function. Liver Transpl 21:79-88, 2015. © 2014 AASLD.

Project description:Living donor kidney transplantation (LDKT) offers better quality of life and clinical outcomes, including patient survival, compared with remaining on dialysis or receiving a deceased donor kidney transplant. Although LDKT education within transplant centers for both potential recipients and living donors is very important, outreach and education to kidney patients in settings other than transplant centers and to the general public is also critical to increase access to this highly beneficial treatment. In June 2014, the American Society of Transplantation's Live Donor Community of Practice, with the support of 10 additional sponsors, convened a consensus conference to determine best practices in LDKT, including a workgroup focused on developing a set of recommendations for optimizing outreach and LDKT education outside of transplant centers. Members of this workgroup performed a structured literature review, conducted teleconference meetings, and met in person at the 2-day conference. Their efforts resulted in consensus around the following recommendations. First, preemptive transplantation should be promoted through increased LDKT education by primary care physicians and community nephrologists. Second, dialysis providers should be trained to educate their own patients about LDKT and deceased donor kidney transplantation. Third, partnerships between community organizations, organ procurement organizations, religious organizations, and transplant centers should be fostered to support transplantation. Fourth, use of technology should be improved or expanded to better educate kidney patients and their support networks. Fifth, LDKT education and outreach should be improved for kidney patients in rural areas. Finally, a consensus-driven, evidence-based public message about LDKT should be developed. Discussion of the effect and potential for implementation around each recommendation is featured, particularly regarding reducing racial and socioeconomic disparities in access to LDKT. To accomplish these recommendations, the entire community of professionals and organizations serving kidney patients must work collaboratively toward ensuring accurate, comprehensive, and up-to-date LDKT education for all patients, thereby reducing barriers to LDKT access and increasing LDKT rates.
