Living donor kidney transplant is the ideal treatment option for end-stage renal disease; however, the decision to pursue living donor kidney transplant is complex and challenging. Measurement invariance of living donor kidney transplant Decisional Balance and Self-Efficacy across gender (male/female), race (Black/White), and education level (no college/college or higher) were examined using a sequential approach. Full strict invariance was found for Decisional Balance and Self-Efficacy for gend ...[more]

Project description:PURPOSE OF REVIEW:For the more than 636,000 adults with end-stage renal disease (ESRD) in the U.S., kidney transplantation is the preferred treatment compared to dialysis. Living donor kidney transplantation (LDKT) comprised 31% of kidney transplantations in 2015, an 8% decrease since 2004. We aimed to summarize the current literature on decision aids that could be used to improve LDKT rates. RECENT FINDINGS:Decision aids are evidence-based tools designed to help patients and their families make difficult treatment decisions. LDKT decision aids can help ESRD patients, patients' family and friends, and healthcare providers engage in treatment decisions and thereby overcome multifactorial LDKT barriers. SUMMARY:We identified 12 LDKT decision aids designed to provide information about LDKT, and/or to help ESRD patients identify potential living donors, and/or to help healthcare providers make decisions about treatment for ESRD or living donation. Of these, 4 were shown to be effective in increasing LDKT, donor inquiries, LDKT knowledge, and willingness to discuss LDKT. Although each LDKT decision aid has limitations, adherence to decision aid development guidelines may improve decision aid utilization and access to LDKT.

Project description:Blacks receive live donor kidney transplant (LDKT) less often than patients of all other races. We evaluated the effectiveness of educational interventions in removing barriers to LDKT for blacks.Patients were randomized to three interventions in which health educator(s) delivered an intervention to (a) the patient and his/her guests in the patient's home (house calls [HC], n=54), (b) clusters of patients and their guests in the transplant center (group based [GB], n=49), and (c) the individual patient alone in the transplant center (individual counseling [IC], n=49).At the 2-year endpoint, 15% (n=8), 8% (n=4), and 6% (n=3) of HC, GB, and IC patients, respectively, received LDKT (P=0.30). Patients in the HC group were more likely than patients in the GB and IC groups to have at least one donor inquiry (82% vs. 61% vs. 47%, P=0.001) and evaluation (65% vs. 39% vs. 27%, P<0.001). Patients in the HC group also were more likely to have higher knowledge, fewer concerns, and higher willingness to talk to others about donation 6 weeks after intervention.These findings underscore the importance of including the patient's social network in LDKT education and the potential of the HC intervention to reduce racial disparity in LDKT rates.

Project description:The best treatment option for many patients with kidney failure is a kidney transplant from a living donor. Countries that successfully increase their rate of living kidney donation will decrease their reliance on dialysis, the most expensive and high-risk form of kidney replacement therapy. Outlined here are some barriers that prevent some patients from pursuing living kidney donation and current knowledge on some potential solutions to these barriers. Also described are strategies to promote living kidney donation in a defensible system of practice. Safely increasing the rate of living kidney donation will require better programs and policies to improve the experiences of living donors and their recipients, to safeguard the practice for years to come.

Project description:Kidney transplantation is regarded as the best treatment option for patients with end-stage renal disease. However, living-donor recipients (LDRs) and deceased-donor recipients (DDRs) still face challenges in transplant-specific emotional adjustment post-transplantation. Research distinguishing emotional adjustment between transplant groups has been limited to Western settings, with little attention given to Asian populations. As such, documenting and comparing the emotional adjustment of LDRs and DDRs in an ethnically diverse Asian setting in Singapore and identifying factors associated with emotional adjustment are of interest. Methods:One hundred eighty-two kidney transplant patients (106 LDRs and 76 DDRs) completed measures of generic distress (Depression, Anxiety, Stress Scale-21) and transplantation-specific emotional and behavioral outcomes (Transplant Effects Questionnaire). Results:LDRs were significantly younger (P = 0.019) and had higher education levels (P = 0.007), higher personal income (P < 0.001), shorter dialysis vintage (P < .001), and higher estimated glomerular filtration rates (eGFRs) (P = 0.002) compared with DDRs. Generic symptoms of depression and stress were very low; however, 29.2% of LDRs and 19.7% of DDRs experienced moderate to severe symptoms of anxiety. Similarly, 83.0% of LDRs and 72.4% of DDRs reported high levels of transplant-specific worry. Multivariate models showed younger patients expressing greater generic distress, and transplant-specific worry (P < 0.01), despite higher eGFRs (P < 0.05). ANCOVA controlling for casemix differences showed that LDRs experienced higher feelings of guilt (P = 0.004) and greater willingness to disclosure (P = 0.041). Conclusions:Clinicians should be vigilant of younger kidney transplant patients who have greater risk of poorer emotional adjustment. Future interventions should target alleviating anxiety and transplant-specific worry.

Project description:ImportanceIt is unclear whether center-level factors are associated with racial equity in living donor kidney transplant (LDKT).ObjectiveTo evaluate center-level factors and racial equity in LDKT during an 11-year time period.Design, setting, and participantsA retrospective cohort longitudinal study was completed in February 2023, of US transplant centers with at least 12 annual LDKTs from January 1, 2008, to December 31, 2018, identified in the Health Resources Services Administration database and linked to the US Renal Data System and the Scientific Registry of Transplant Recipients.Main outcomes and measuresObserved and model-based estimated Black-White mean LDKT rate ratios (RRs), where an RR of 1 indicates racial equity and values less than 1 indicate a lower rate of LDKT of Black patients compared with White patients. Estimated yearly best-case center-specific LDKT RRs between Black and White individuals, where modifiable center characteristics were set to values that would facilitate access to LDKT.ResultsThe final cohorts of patients included 394 625 waitlisted adults, of whom 33.1% were Black and 66.9% were White, and 57 222 adult LDKT recipients, of whom 14.1% were Black and 85.9% were White. Among 89 transplant centers, estimated yearly center-level RRs between Black and White individuals accounting for center and population characteristics ranged from 0.0557 in 2008 to 0.771 in 2018. The yearly median RRs ranged from 0.216 in 2016 to 0.285 in 2010. Model-based estimations for the hypothetical best-case scenario resulted in little change in the minimum RR (from 0.0557 to 0.0549), but a greater positive shift in the maximum RR from 0.771 to 0.895. Relative to the observed 582 LDKT in Black patients and 3837 in White patients, the 2018 hypothetical model estimated an increase of 423 (a 72.7% increase) LDKTs for Black patients and of 1838 (a 47.9% increase) LDKTs for White patients.Conclusions and relevanceIn this cohort study of patients with kidney failure, no substantial improvement occurred over time either in the observed or the covariate-adjusted estimated RRs. Under the best-case hypothetical estimations, modifying centers' participation in the paired exchange and voucher programs and increased access to public insurance may contribute to improved racial equity in LDKT. Additional work is needed to identify center-level and program-specific strategies to improve racial equity in access to LDKT.

Project description:ImportanceThe proportion of living donor kidney transplants from donors unrelated to their recipients is increasing in the US.ObjectiveTo examine the association between donor-recipient biological relationship and allograft survival after living donor kidney transplant.Design, setting, and participantsThis retrospective cohort study used Organ Procurement and Transplantation Network data on US adult living donor kidney transplants (n = 86 154) performed from January 1, 2000, to December 31, 2014, excluding cases in which recipients previously received a kidney transplant (n = 10 342) or key data were missing (n = 2832). Last follow-up was March 20, 2020.ExposuresDonor-recipient biological relationship.Main outcomes and measuresThe primary outcome was death-censored allograft failure. Univariate and multivariable time-to-event analyses were performed for death-censored allograft failure for the overall cohort, then separately for recipients with and without primary diagnoses of cystic kidney disease and for transplants from African American and non-African American donors.ResultsAmong the 72 980 transplant donor and recipients included in the study (median donor age, 41 years; interquartile range [IQR], 32-50 years; 43 990 [60%] female; 50 014 [69%] White), 43 174 (59%) donors and recipients were biologically related and 29 806 (41%) were unrelated. Donors related to their recipients were younger (median [IQR] age, 39 [31-48] vs 44 [35-52] years) and less likely to be female (24 848 [58%] vs 19 142 [64%]) or White (26 933 [62%] vs 23 081 [77%]). Recipients related to their donors were younger (median [IQR] age, 48 [34-58] vs 50 [40-58] years), more likely to be female (18 035 [42%] vs 10 530 [35%]), and less likely to have cystic kidney disease (2530 [6%] vs 4600 [15%]). Related pairs had fewer HLA mismatches overall (median [IQR], 3 [2-3] vs 5 [4-5]). After adjustment for HLA mismatches, donor and recipient characteristics, and transplant era, donor-recipient biological relationship was associated with higher death-censored allograft failure (hazard ratio, 1.05; 95% CI, 1.01-1.10; P = .03). When stratified by primary disease, this association persisted only for recipients without cystic kidney disease. When stratified by donor race, this association persisted only for transplants from African American donors.Conclusions and relevanceIn this cohort study, living donor kidney transplants from donors biologically related to their recipients had higher rates of allograft failure than transplants from donors unrelated to their recipients after HLA matching was accounted for. Further study is needed to determine which genetic or socioenvironmental factors are associated with this finding.

Project description:Using the Scientific Registry of Transplant Recipients, we examined the association between donor-recipient biologic relationship and long-term recipient and allograft survival among glomerulonephritis (GN) patients. Four GN types were studied: membranous nephropathy, IgA, lupus-associated nephritis, and focal segmental glomerulosclerosis (FSGS). We identified all adult primary living-donor recipients between 2000 and 2018 (n = 19,668): related (n = 10,437); unrelated (n = 9,231). Kaplan-Meier curves were generated for the recipient, death-censored graft survival and death with functioning graft through ten years post-transplant. Multivariable Cox proportional hazard models were used to examine the association between the donor-recipient relationship and outcomes of interest. There was an increased risk for acute rejection by 12 months post-transplant among the unrelated compared to the related group in IgA (10.1% vs. 6.5%, p<0.001), FSGS (12.1% vs. 10%, p-0.016), and lupus nephritis (11.8% vs. 9.2%; p-0.049). The biological donor-recipient relationship was not associated with a worse recipient or graft survival or death with functioning graft in the multivariable models. These findings are consistent with the known benefits of living-related-donor kidney transplants and counter the reports of the potential adverse impact of the donor-recipient biologic relationship on allograft outcomes.

Project description:In this article, we describe a province-wide collaborative project in which we adapted the Explore Transplant (ET) education program for use in Ontario, Canada, to develop Explore Transplant Ontario (ETO). Kidney transplantation (KT), especially living donor kidney transplantation (LDKT), is the best treatment for many patients with end-stage kidney disease (ESKD), with the best patient survival and quality of life and also reduced health care costs. Yet KT and LDKT are underutilized both internationally and in Canada. Research has demonstrated that patients with ESKD who receive personalized transplant education are more likely to complete the transplant evaluation process and to receive LDKT compared with patients who do not receive this education.Research expertise of the lead authors and Medline search of studies assessing the impact of education interventions on access to KT and LDKT.The ET program, developed by Dr Amy Waterman, has been used in thousands of patients with ESKD in the United States to enhance KT and LDKT knowledge. To adapt this program for use in Ontario, we convened a working group, including patient representatives, nephrologists, transplant coordinators, dialysis nurses, and patient educators from all Ontario KT centers and selected dialysis units. In an iterative process concluding in a consensus workshop, the working group reviewed and edited the text of the original ET program and suggested changes to the videos.The adapted program reflects the Ontario health care environment and responds to the specific needs of patients with chronic kidney disease (CKD) in the province. The videos feature Ontario transplant nephrologists, transplant coordinators, and patients, representative of the ethnic diversity in Ontario, sharing their transplant experience and expertise. Despite the changes, ETO is consistent with the quality and style of the original ET program. At the end of this article, we summarize subsequent steps to test and utilize ETO. Those projects, specifically the ETO pilot study and a multicomponent quality improvement initiative to increase utilization of KT and LDKT across Ontario, will be described in full in future papers.This article describes a provincial initiative; therefore, our findings may not be fully generalizable without further considerations. The adapted education program has not yet been tested in large trial for effectiveness.As a program grounded in the theoretical model of behavior change, ETO places patients with ESKD at the center of a complex process of navigating renal replacement therapy modalities and acknowledges a broad range of patient values, priorities, and states of readiness to pursue KT.

Project description:ImportanceLiving donor kidney transplant (LDKT) is the ideal treatment for end-stage kidney disease, but racial disparities in LDKT have increased over the last 2 decades. Recipient clinical and social factors do not account for LDKT racial inequities, although comprehensive measures of community-level vulnerability have not been assessed.ObjectiveTo determine if racial disparities persist in LDKT independent of community-level vulnerability.Design, setting, and participantsThis retrospective, multicenter, cross-sectional study included data from 19 287 adult kidney-only transplant recipients in the Scientific Registry of Transplant Recipients. The study included individuals who underwent transplant between January 1 and December 31, 2018.ExposuresRecipient race and the 2018 US Centers for Disease Control and Prevention Social Vulnerability Index (SVI). Census tract-level SVI data were linked to census tracts within each recipient zip code. The median SVI measure among the census tracts within a zip code was used to describe community-level vulnerability.Main outcomes and measuresKidney transplant donor type (deceased vs living). Modified Poisson regression was used to evaluate the association between SVI and LDKT, and to estimate LDKT likelihood among races, independent of community-level vulnerability and recipient-level characteristics.ResultsAmong 19 287 kidney transplant recipients, 6080 (32%) received LDKT. A total of 11 582 (60%) were male, and the median (interquartile range) age was 54 (43-63) years. There were 760 Black LDKT recipients (13%), 4865 White LDKT recipients (80%), and 455 LDKT recipients of other races (7%; American Indian, Asian, multiracial, and Pacific Islander). Recipients who lived in communities with higher SVI (ie, more vulnerable) had lower likelihood of LDKT compared with recipients who lived in communities with lower SVI (ie, less vulnerable) (adjusted relative risk [aRR], 0.97; 95% CI, 0.96-0.98; P < .001). Independent of community-level vulnerability, compared with White recipients, Black recipients had 37% lower likelihood (aRR, 0.63; 95% CI, 0.59-0.67; P < .001) and recipients of other races had 24% lower likelihood (aRR, 0.76; 95% CI, 0.70-0.82; P < .001) of LDKT. The interaction between SVI and race was significant among Black recipients, such that the disparity in LDKT between Black and White recipients increased with greater community-level vulnerability (ratio of aRRs, 0.67; 95% CI, 0.51-0.87; P = .003).Conclusions and relevanceCommunity-level vulnerability is associated with access to LDKT but only partially explains LDKT racial disparities. The adverse effects of living in more vulnerable communities were worse for Black recipients. The interaction of these constructs is worrisome and suggests evaluation of other health system factors that may contribute to LDKT racial disparities is needed.

Project description:IntroductionDespite the different assays available for immune-risk stratification before living-donor kidney transplantation (LDKT), the precise type and number of tests to perform remain uncertain.MethodsIn a cohort of 330 consecutive LDKT patients, all of which were complement-dependent cytotoxicity (CDC)-crossmatch negative, we retrospectively analyzed the impact on main clinical outcomes of most sensitive immunoassays (complement-dependent cytotoxicity-panel-reactive antibody [CDC-PRA], flow cytometry crossmatch [FC-XM], donor-specific antibodies [DSAs], and their complement-binding capacity DSA-C3d]), together with donor/recipient HLA eplet matching. Mean follow-up was 67 months (range 24-190 months).ResultsOf 330 patients, 35 (11%) showed a CDC-PRA >20%; 17 (5%) FC-XM+; 30 (9%) DSA+, 18(5%) DSA-C3d+, with low overlapping results (10 patients positive in all donor-specific tests). Unlike HLA allele compatibility, the mean number of HLA class II eplet mismatches was higher in LDKT patients with positive baseline test results. DSA-C3d+ showed higher mean fluorescence intensity (MFI) DSA, with a cut-off MFI of 6192 accurately predicting complement fixation (area under the curve = 0.85, P = 0.008). Although all assays were associated with acute rejection (AR), only DSA-C3d+ (odds ratio [OR] = 6.64, P = 0.038) or high MFI-DSA (OR = 7.54, P = 0.038) independently predicted AR. Likewise, poorly HLA class II eplet-matched patients were at higher risk for AR, particularly patients with negative baseline test results (OR = 1.14, P = 0.019). Finally, previous AR and FC-XM+/DSA+, regardless of C3d positivity, independently predicted graft loss.ConclusionCombining FC-XM and solid-phase assays with the evaluation of donor/recipient HLA eplet mismatches, are most accurate tools for immune-risk stratification prior LDKT.
