Individual- and Community-Level Socioeconomic Status and Deceased Donor Renal Transplant Outcomes. J Racial Ethn Health Disparities 2023:10.1007/s40615-023-01851-8. [PMID: 37962790 DOI: 10.1007/s40615-023-01851-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Revised: 10/21/2023] [Accepted: 10/24/2023] [Indexed: 11/15/2023]
Abstract
BACKGROUND This study examined the relationship between socioeconomic status (SES), race, and ethnicity and clinical outcomes following deceased donor kidney transplant (DDKT) at a high-volume transplant center. METHODS This retrospective cohort study used regression models and survival analyses to examine the relationship between individual- and community-level SES, race, and ethnicity and DDKT outcomes (i.e., delayed graft function, graft failure, mortality) adjusting for potential confounders. RESULTS The analytic sample included 3366 patients; 40.7% (n = 1370) were female, the mean age was 54.7 (SD = 13.3) years, 49.3% were non-Hispanic White, and the median follow-up time was 39.5 months (IQR = 24.2-68.1). Patients living in the most disadvantaged communities (using the US Census data) had a higher likelihood of delayed graft function (adjusted relative risk [RR] = 1.12, p = 0.042) and a higher hazard of mortality (adjusted hazard ratio [HR] = 1.32, p = 0.025) compared to patients living in the least disadvantaged communities. Patients without a high school diploma had a higher risk of delayed graft function compared to patients with an associate degree or more (RR = 1.37, p < 0.001). Patients with public insurance coverage had a higher risk of delayed graft function (RR = 1.24, p < 0.001) and a higher hazard of mortality (HR = 1.37, p < 0.001) and graft failure (HR = 1.71, p < 0.001) compared to patients without public insurance. There were no differences in graft failure or mortality by race and ethnicity. CONCLUSIONS SES was not consistently associated with outcomes following DDKT; however, many of the predictors were associated with delayed graft function. With a large and diverse sample size, these findings further the heterogeneity of the present renal transplant research suggesting the need for further investigation to guide implementation of innovative strategies and interventions.

Abstract
Polycyclic aromatic hydrocarbons (PAHs) are environmental pollutants formed from the incomplete combustion of carbon-containing products. Exposure can occur through ingestion or inhalation and has been linked to depression, stroke, liver disease, asthma, diabetes, heart failure, and cancer. Few studies have investigated the association between exposure to PAHs and chronic kidney disease (CKD) in humans. This study aims to investigate the association between seven urinary PAH concentrations (1-hydroxynaphthalene, 2-hydroxynaphthalene, 3-hydroxyfluorene 2-hydroxyfluorene, 1-hydroxyphenanthrene, 1-hydroxypyrene, and 2 & 3-hydroxyphenanthrene) and CKD in the US adult population. A cross-sectional analysis using the 2015-2016 National Health and Nutrition Examination Survey (NHANES) dataset was conducted. CKD was defined with estimated glomerular filtration rate (eGFR) and albumin to creatinine ratio (ACR). Participants with an eGFR < 60 ml/min/1.73m2 or ACR > 30 mg/gm were considered to have CKD. A specialized complex survey design analysis package using R version 4.0.3 was used in the data analysis. Multivariate logistic regression was used to study the correlation between seven forms of urinary PAH concentrations and CKD associated with abnormal eGFR or ACR. The models were adjusted for lifestyle and demographic factors. The study included a total of 4117 adults aged ≥ 20 years, with 49.6% males and 50.4% females. Urinary 2-hydroxynaphthalene (OR: 1.600, 95% CI: 1.141, 2.243) was significantly associated with an increased odds of CKD; the other six forms of urinary PAHs were not associated with CKD. Non-Hispanic Black (OR: 1.569, 95% CI: 1.168, 2.108), age of 60 years and older (OR: 2.546, 95% CI: 1.865, 3.476), and BMIs of underweight (OR: 2.386, 95% CI: 1.259, 4.524) and obese (OR: 1.407, 95% CI: 1.113, 1.778) all had significantly increased odds for CKD. Our study concluded that urinary 2-hydroxynaphthalene, a form of PAH, is significantly associated with CKD.

Abstract
PURPOSE OF REVIEW Health disparity in minority populations has been increasingly recognized over the last decade. The COVID-19 pandemic sheds a bright light on this very issue impressing upon the need for more research regarding healthcare in disparate populations. Although kidney transplantation remains the treatment of choice for end-stage renal disease management and longevity of life, access to transplantation remains a critical barrier in minority populations. The literature on disparity in access abounds but remains limited with regards to posttransplantation outcomes. The purpose of this review is to draw attention to existing research and literature in posttransplant outcomes and highlight the overall knowledge gap that persists in postkidney transplant care among disparate populations. RECENT FINDINGS The current review focuses on important paradigm shifts in the determinants of outcomes in posttransplantation care in minority populations. It emphasizes a departure from immune mediated causes to more salient health inequities and socioeconomic factors contributing to patient and graft survival which require further investigation. SUMMARY Despite increased awareness of health disparity in minority populations, outcomes data postkidney transplantation remains sparse. Critical to the future of kidney transplantation and improved healthcare coordination in minority populations will be a deeper understanding of contributing socio-economic variables in disparate outcomes.

Outcomes and factors leading to graft failure in kidney transplants from deceased donors with acute kidney injury-A retrospective cohort study. PLoS One 2021; 16:e0254115.

Abstract
Due to shortage of donor, kidney transplants (KTs) from donors with acute kidney injury (AKI) are expanding. Although previous studies comparing clinical outcomes between AKI and non-AKI donors in KTs have shown comparable results, data on high-volume analysis of KTs outcomes with AKI donors are limited. This study aimed to analyze the selection trends of AKI donors and investigate the impact of AKI on graft failure using the United states cohort data. We analyzed a total 52,757 KTs collected in the Scientific Registry of Transplant Recipient (SRTR) from 2010 to 2015. The sample included 4,962 (9.4%) cases of KTs with AKI donors (creatinine ≥ 2 mg/dL). Clinical characteristics of AKI and non-AKI donors were analyzed and outcomes of both groups were compared. We also analyzed risk factors for graft failure in AKI donor KTs. Although the incidence of delayed graft function was higher in recipients of AKI donors compared to non-AKI donors, graft and patient survival were not significantly different between the two groups. We found donor hypertension, cold ischemic time, the proportion of African American donors, and high KDPI were risk factors for graft failure in AKI donor KTs. KTs from deceased donor with AKI showed comparable outcomes. Thus, donors with AKI need to be considered more actively to expand donor pool. Caution is still needed when donors have additional risk factors of graft failure.

Abstract
Kidney transplantation is the ideal treatment option for patients with end-stage kidney disease (ESKD). Since there is clear mortality benefit to receiving a transplant regardless of comorbidities and age, the gold standard of care should focus on attaining kidney transplantation and minimizing, or better yet eliminating, time on dialysis. Unfortunately, only a small percentage of patients with ESKD receive a kidney transplant. Several barriers to kidney transplantation have been identified. Barriers can largely be grouped into three categories: patient-related, physician/provider-related, and system-related. Several barriers fall into multiple categories and play a role at various levels within the healthcare system. Acknowledging and understanding these barriers will allow transplant centers and dialysis facilities to make the necessary interventions to mitigate these disparities, optimize the transplant evaluation process, and improve patient outcomes. This review will discuss these barriers and potential interventions to increase access to kidney transplantation.

Beyond Single Nucleotide Polymorphisms: CYP3A5∗3∗6∗7 Composite and ABCB1 Haplotype Associations to Tacrolimus Pharmacokinetics in Black and White Renal Transplant Recipients. Front Genet 2020; 11:889. [PMID: 32849848 PMCID: PMC7433713 DOI: 10.3389/fgene.2020.00889] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2020] [Accepted: 07/20/2020] [Indexed: 12/12/2022] Open
Abstract
Interpatient variability in tacrolimus pharmacokinetics is attributed to metabolism by cytochrome P-450 3A5 (CYP3A5) isoenzymes and membrane transport by P-glycoprotein. Interpatient pharmacokinetic variability has been associated with genotypic variants for both CYP3A5 or ABCB1. Tacrolimus pharmacokinetics was investigated in 65 stable Black and Caucasian post-renal transplant patients by assessing the effects of multiple alleles in both CYP3A5 and ABCB1. A metabolic composite based upon the CYP3A5 polymorphisms: ∗3(rs776746), ∗6(10264272), and ∗7(41303343), each independently responsible for loss of protein expression was used to classify patients as extensive, intermediate and poor metabolizers. In addition, the role of ABCB1 on tacrolimus pharmacokinetics was assessed using haplotype analysis encompassing the single nucleotide polymorphisms: 1236C > T (rs1128503), 2677G > T/A(rs2032582), and 3435C > T(rs1045642). Finally, a combined analysis using both CYP3A5 and ABCB1 polymorphisms was developed to assess their inter-related influence on tacrolimus pharmacokinetics. Extensive metabolizers identified as homozygous wild type at all three CYP3A5 loci were found in 7 Blacks and required twice the tacrolimus dose (5.6 ± 1.6 mg) compared to Poor metabolizers [2.5 ± 1.1 mg (P < 0.001)]; who were primarily Whites. These extensive metabolizers had 2-fold faster clearance (P < 0.001) with 50% lower AUC∗ (P < 0.001) than Poor metabolizers. No differences in C12 h were found due to therapeutic drug monitoring. The majority of blacks (81%) were classified as either Extensive or Intermediate Metabolizers requiring higher tacrolimus doses to accommodate the more rapid clearance. Blacks who were homozygous for one or more loss of function SNPS were associated with lower tacrolimus doses and slower clearance. These values are comparable to Whites, 82% of who were in the Poor metabolic composite group. The ABCB1 haplotype analysis detected significant associations of the wildtype 1236T-2677T-3435T haplotype to tacrolimus dose (P = 0.03), CL (P = 0.023), CL/LBW (P = 0.022), and AUC∗ (P = 0.078). Finally, analysis combining CYP3A5 and ABCB1 genotypes indicated that the presence of the ABCB1 3435 T allele significantly reduced tacrolimus clearance for all three CPY3A5 metabolic composite groups. Genotypic associations of tacrolimus pharmacokinetics can be improved by using the novel composite CYP3A5∗3∗4∗5 and ABCB1 haplotypes. Consideration of multiple alleles using CYP3A5 metabolic composites and drug transporter ABCB1 haplotypes provides a more comprehensive appraisal of genetic factors contributing to interpatient variability in tacrolimus pharmacokinetics among Whites and Blacks.

Renal Transplantation Is Associated with Increased Complications Following Spinal Fusion Operations: Analysis of a National Database. World Neurosurg 2020; 137:e269-e277. [PMID: 32006732 DOI: 10.1016/j.wneu.2020.01.167] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2019] [Revised: 01/20/2020] [Accepted: 01/21/2020] [Indexed: 11/23/2022]
Abstract
BACKGROUND Improved postoperative care for renal transplant recipients has advanced both duration and overall quality of life. However, degenerative spinal pathology is increasingly prevalent after transplant. Outcomes following spinal fusion among the renal transplant population in the United States are rarely addressed. METHODS The Healthcare Cost and Utilization Project National Inpatient Sample database was employed. Cases in years 2008-2014 for patients ≥18 years old receiving spinal fusion, exploration/decompression, and/or spinal revision/re-fusion surgeries were included. Cases were divided into kidney transplant recipients (KTR) and non-kidney transplant recipients. Complications, demographics, and socioeconomic outcomes were compared between cohorts. RESULTS Of 579,726 patients who met inclusion criteria, 685 (0.1%) were KTRs. The KTR population was older and included more men compared with the non-kidney transplant recipient population (60.1 years vs. 56.6 years, P < 0.001; 58% male vs. 45.5% male, P < 0.001). KTRs experienced higher total complication rates (29.8% vs. 18.9%, P < 0.001). Prevalence of acute posthemorrhagic anemia and need for transfusion was markedly higher for KTRs (15.8% vs. 9.1%, P < 0.001; 13.6% vs. 6.2%, P < 0.001). Multivariate analysis revealed longer length of stay (median 1.23 days, interquartile range 0.94-1.53, P < 0.001), lower routine discharge (odds ratio = 0.57, 95% confidence interval 0.48-0.69, P < 0.001), and higher discharge to alternative care facilities (odds ratio = 1.91, 95% confidence interval 1.57-2.33, P < 0.001) for KTRs. The inpatient course for KTRs undergoing spinal operations was significantly costlier ($87,445 vs. $71,589, P < 0.001). CONCLUSIONS History of renal transplant was associated with increased inpatient medical and socioeconomic complications following spinal fusion. Physicians and patients must understand and respect the potentially increased perioperative challenges facing KTRs.

Abstract
OBJECTIVE The aim of this study was to provide a contemporary analysis of longitudinal kidney transplant outcomes and to evaluate potential causes of ethnic disparities among African American (AA) and Caucasian American (CA) patients undergoing kidney transplantation at our institution. PATIENTS AND METHODS 1400 patients were identified who underwent kidney transplantation from 2003 to 2013 from a large, academic institution in Cleveland, OH. Relevant recipient and donor demographic and clinical covariates were obtained from an institutional transplant database. Simple descriptive statistics and comparative survival analyses were performed to assess overall survival and graft survival. RESULTS The final cohort was comprised of 341 AA and 1059 CA patients. AAs were less likely to receive a living donor transplant (27.6% vs. 57.2%, p < 0.001) compared to CAs. Overall patient survival did not significantly differ between the two groups even when stratified by ethnicity. However, AAs had a significantly lower rate of graft survival (p < 0.001). On stratified analysis, there was no difference in the rate of graft survival among AAs and CAs who received living donor grafts. On univariate analysis, AAs demonstrated higher rates of immunosuppression non-compliance and chronic rejection (both p < 0.05). On multivariate analysis, AA recipient ethnicity (HR 1.56, p = 0.047), recipient history of diabetes (HR 1.67, p < 0.001), and AA donor ethnicity (HR 1.56, p = 0.047) were significantly associated with graft failure. CONCLUSION AAs undergoing deceased donor renal transplantation demonstrated lower graft survival compared to CAs. Conversely, this disparity did not exist among AAs undergoing living donor transplantation. AAs had higher rates of deceased donor transplantation, immunosuppression non-compliance, chronic rejection, and diabetes. Opportunities exist to use patient education, alternative immunosuppression regimens, and living transplantation to close the ethnic disparity in renal allograft survival.

Racial/ethnic disparities in waitlisting for deceased donor kidney transplantation 1 year after implementation of the new national kidney allocation system. Am J Transplant 2018; 18:1936-1946. [PMID: 29603644 PMCID: PMC6105401 DOI: 10.1111/ajt.14748] [Citation(s) in RCA: 81] [Impact Index Per Article: 13.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2017] [Revised: 02/26/2018] [Accepted: 03/20/2018] [Indexed: 01/25/2023]
Abstract
The impact of a new national kidney allocation system (KAS) on access to the national deceased-donor waiting list (waitlisting) and racial/ethnic disparities in waitlisting among US end-stage renal disease (ESRD) patients is unknown. We examined waitlisting pre- and post-KAS among incident (N = 1 253 100) and prevalent (N = 1 556 954) ESRD patients from the United States Renal Data System database (2005-2015) using multivariable time-dependent Cox and interrupted time-series models. The adjusted waitlisting rate among incident patients was 9% lower post-KAS (hazard ratio [HR]: 0.91; 95% confidence interval [CI], 0.90-0.93), although preemptive waitlisting increased from 30.2% to 35.1% (P < .0001). The waitlisting decrease is largely due to a decline in inactively waitlisted patients. Pre-KAS, blacks had a 19% lower waitlisting rate vs whites (HR: 0.81; 95% CI, 0.80-0.82); following KAS, disparity declined to 12% (HR: 0.88; 95% CI, 0.85-0.90). In adjusted time-series analyses of prevalent patients, waitlisting rates declined by 3.45/10 000 per month post-KAS (P < .001), resulting in ≈146 fewer waitlisting events/month. Shorter dialysis vintage was associated with greater decreases in waitlisting post-KAS (P < .001). Racial disparity reduction was due in part to a steeper decline in inactive waitlisting among minorities and a greater proportion of actively waitlisted minority patients. Waitlisting and racial disparity in waitlisting declined post-KAS; however, disparity remains.

Abstract
Before the 2014 implementation of a new kidney allocation system by the United Network for Organ Sharing, white patients were more likely than black or Hispanic patients to receive a kidney transplant. To determine the effect of the new allocation system on these disparities, we examined data for 179,071 transplant waiting list events in the period June 2013-September 2016, and we calculated monthly transplantation rates (34,133 patients actually received transplants). Implementation of the new system was associated with a narrowing of the disparities in the average monthly transplantation rates by 0.29 percentage point for blacks compared to whites and by 0.24 percentage point for Hispanics compared to whites, which resulted in both disparities becoming nonsignificant after implementation of the new system.

Overall Graft Loss Versus Death-Censored Graft Loss: Unmasking the Magnitude of Racial Disparities in Outcomes Among US Kidney Transplant Recipients. Transplantation 2017; 101:402-410.

Abstract
BACKGROUND Black kidney transplant recipients experience disproportionately high rates of graft loss. This disparity has persisted for 40 years, and improvements may be impeded based on the current public reporting of overall graft loss by US regulatory organizations for transplantation. METHODS Longitudinal cohort study of kidney transplant recipients using a data set created by linking Veterans Affairs and US Renal Data System information, including 4918 veterans transplanted between January 2001 and December 2007, with follow-up through December 2010. Multivariable analysis was conducted using 2-stage joint modeling of random and fixed effects of longitudinal data (linear mixed model) with time to event outcomes (Cox regression). RESULTS Three thousand three hundred six non-Hispanic whites (67%) were compared with 1612 non-Hispanic black (33%) recipients with 6.0 ± 2.2 years of follow-up. In the unadjusted analysis, black recipients were significantly more likely to have overall graft loss (hazard ratio [HR], 1.19; 95% confidence interval [95% CI], 1.07-1.33), death-censored graft loss (HR, 1.67; 95% CI, 1.45-1.92), and lower mortality (HR, 0.83; 95% CI, 0.72-0.96). In fully adjusted models, only death-censored graft loss remained significant (HR, 1.38; 95% CI, 1.12-1.71; overall graft loss [HR, 1.08; 95% CI, 0.91-1.28]; mortality [HR, 0.84; 95% CI, 0.67-1.06]). A composite definition of graft loss reduced the magnitude of disparities in blacks by 22%. CONCLUSIONS Non-Hispanic black kidney transplant recipients experience a substantial disparity in graft loss, but not mortality. This study of US data provides evidence to suggest that researchers should focus on using death-censored graft loss as the primary outcome of interest to facilitate a better understanding of racial disparities in kidney transplantation.

Abstract
BACKGROUND Racial disparities in African-American (AA) kidney transplant have persisted for nearly 40 years, with limited data available on the scope of this issue in the contemporary era of transplantation. METHODS Descriptive retrospective cohort study of US registry data including adult solitary kidney transplants between Jan 1, 2005 to Dec 31, 2009. RESULTS 60,695 recipients were included; 41,426 Caucasians (68%) and 19,269 AAs (32%). At baseline, AAs were younger, had lower college graduation rates, were more likely to be receiving public health insurance and have diabetes. At one-year post-transplant, AAs had 62% higher risk of graft loss (RR 1.62, 95% CI 1.50-1.75) which increased to 93% at five years (RR 1.93, 95% CI 1.85-2.01). Adjusted risk of graft loss, accounting for baseline characteristics, was 60% higher in AAs (HR 1.61 [1.52-1.69]). AAs had significantly higher risk of acute rejection and delayed graft function. CONCLUSION AAs continue to experience disproportionately high rates of graft loss within the contemporary era of transplant, which are related to a convergence of an array of socioeconomic and biologic risk factors.

Abstract
Disparities in outcomes for African American (AA) kidney transplant recipients have persisted for 40 years without a comprehensive analysis of evolving trends in the risks associated with this disparity. Here we analyzed U.S. transplant registry data, which included adult Caucasian or AA solitary kidney recipients undergoing transplantation between 1990 and 2009 comprising 202,085 transplantations. During this 20-year period, the estimated rate of 5-year graft loss decreased from 27.6% to 12.8%. Notable trends in baseline characteristics that significantly differed by race over time included the following: increased prevalence of diabetes from 2001 to 2009 in AAs (5-year slope difference: 3.4%), longer time on the waiting list (76.5 more days per 5 years in AAs), fewer living donors in AAs from 2003 to 2009 (5-year slope difference: -3.36%), more circulatory death donors in AAs from 2000-09 (5-year slope difference: 1.78%), and a slower decline in delayed graft function in AAs (5-year slope difference: 0.85%). The absolute risk difference between AAs and Caucasians for 5-year graft loss significantly declined over time (-0.92% decrease per 5 years), whereas the relative risk difference actually significantly increased (3.4% increase per 5 years). These results provide a mixed picture of both promising and concerning trends in disparities for AA kidney transplant recipients. Thus, although the disparity for graft loss has significantly improved, equity is still far off, and other disparities, including living donation rates and delayed graft function rates, have widened during this time.

Abstract
Background There is wide variation in referral for kidney transplant and preemptive kidney transplant (PKT). Patient characteristics such as age, race, sex and geographic location have been cited as contributing factors to this disparity. We hypothesize that the characteristics of nephrologists interplay with the patients' characteristics to influence the referral decision. In this study, we used hypothetical case scenarios to assess nephrologists' decisions regarding transplant referral. Methods A total of 3180 nephrologists were invited to participate. Among those interested, 252 were randomly selected to receive a survey in which nephrologists were asked whether they would recommend transplant for the 25 hypothetical patients. Logistic regression models with single covariates and multiple covariates were used to identify patient characteristics associated with likelihood of being referred for transplant and to identify nephrologists' characteristics associated with likelihood of referring for transplant. Results Of the 252 potential participants, 216 completed the survey. A nephrologist's affiliation with an academic institution was associated with a higher likelihood of referral, and being ‘>10 years from fellowship’ was associated with lower likelihood of referring patients for transplant. Patient age <50 years was associated with higher likelihood of referral. Rural location and smoking history/chronic obstructive pulmonary disease were associated with lower likelihood of being referred for transplant. The nephrologist's affiliation with an academic institution was associated with higher likelihood of referring for preemptive transplant, and the patient having a rural residence was associated with lower likelihood of being referred for preemptive transplant. Conclusions The variability in transplant referral is related to patients' age and geographic location as well as the nephrologists' affiliation with an academic institution and time since completion of training. Future educational interventions should emphasize the benefits of kidney transplant and PKT for all population groups regardless of geographic location and age and should target nephrologists in non-academic settings who are 10 or more years from their fellowship training.

Abstract
Earlier studies reported inferior outcomes among black compared with white kidney transplant (KT) recipients. We examined whether this disparity improved in recent decades. Using the Scientific Registry of Transplant Recipients and Cox regression models, we compared all-cause graft loss among 63,910 black and 145,482 white adults who received a first-time live donor KT (LDKT) or deceased donor KT (DDKT) in 1990-2012. Over this period, 5-year graft loss after DDKT improved from 51.4% to 30.6% for blacks and from 37.3% to 25.0% for whites; 5-year graft loss after LDKT improved from 37.4% to 22.2% for blacks and from 20.8% to 13.9% for whites. Among DDKT recipients in the earliest cohort, blacks were 39% more likely than whites to experience 5-year graft loss (adjusted hazard ratio [aHR], 1.39; 95% confidence interval [95% CI], 1.32 to 1.47; P<0.001), but this disparity narrowed in the most recent cohort (aHR, 1.10; 95% CI, 1.03 to 1.18; P=0.01). Among LDKT recipients in the earliest cohort, blacks were 53% more likely than whites to experience 5-year graft loss (aHR, 1.53; 95% CI, 1.27 to 1.83; P<0.001), but this disparity also narrowed in the most recent cohort (aHR, 1.37; 95% CI, 1.17 to 1.61; P<0.001). Analyses revealed no statistically significant differences in 1-year or 3-year graft loss after LDKT or DDKT in the most recent cohorts. Our findings of reduced disparities over the last 22 years driven by more markedly improved outcomes for blacks may encourage nephrologists and patients to aggressively promote access to transplantation in the black community.

Abstract
Living donor liver transplantation (LDLT) is a comparable alternative to deceased donor liver transplantation and can mitigate the risk of dying while waiting for transplant. Although evidence exists of decreased utilization of living donor kidney transplants among racial minorities, little is known about access to LDLT among racial/ethnic minorities. We used Organ Procurement and Transplantation Network/United Network for Organ Sharing data from February 27, 2002 to June 4, 2014 from all adult liver transplant recipients at LDLT-capable transplant centers to evaluate differential utilization of LDLTs based on race/ethnicity. We then used data from 2 major urban transplant centers to analyze donor inquiries and donor rule-outs based on racial/ethnic determination. Nationally, of 35,401 total liver transplant recipients performed at a LDLT-performing transplant center, 2171 (6.1%) received a LDLT. In multivariate generalized estimating equation models, racial/ethnic minorities were significantly less likely to receive LDLTs when compared to white patients. For cholestatic liver disease, the odds ratios of receiving LDLT based on racial/ethnic group for African American, Hispanic, and Asian patients compared to white patients were 0.35 (95% CI, 0.20-0.60), 0.58 (95% CI, 0.34-0.99), and 0.11 (95% CI, 0.02-0.55), respectively. For noncholestatic liver disease, the odds ratios by racial/ethnic group were 0.53 (95% CI, 0.40-0.71), 0.78 (95% CI, 0.64-0.94), and 0.45 (95% CI, 0.33-0.60) respectively. Transplant center-specific data demonstrated that African American patients received fewer per-patient donation inquiries than white patients, whereas fewer African American potential donors were ruled out for obesity. In conclusion, racial/ethnic minorities receive a disproportionately low percentage of LDLTs, due in part to fewer initial inquiries by potential donors. This represents a major inequality in access to a vital health care resource and demands outreach to both patients and potential donors.

Abstract
CONTEXT For adults with end-stage kidney disease, live donor kidney transplant (LDKT) has better outcomes than long-term dialysis and deceased donor kidney transplant. However, black patients receive LDKT at a much lower rate than adults of any other race or ethnicity. OBJECTIVE To examine the LDKT readiness stage of black patients on the transplant waiting list and its association with LDKT knowledge, concerns, and willingness. DESIGN Cross-sectional analysis of baseline data from a randomized controlled trial to improve knowledge and reduce concerns about LDKT.Patients and Setting-One hundred fifty-two black patients on the kidney transplant waiting list at a single transplant center in the northeastern United States. MAIN OUTCOME MEASURES LDKT readiness stage, knowledge, concerns, and willingness to talk to others about living donation. RESULTS Sixty percent of patients were not considering or not yet ready to pursue LDKT, and only 11% had taken action to talk to family members or friends about the possibility of living kidney donation. Patients in later stages of LDKT readiness (ie, who had talked to others about donation or were preparing to do so) had significantly more knowledge (P<.001), fewer concerns (P=.002), and more willingness (P=.001) to talk to others about living donation than those in earlier readiness stages. CONCLUSIONS The large percentage of black patients who are in the earlier stages of LDKT readiness may account for the low rate of LDKT in this patient population at our transplant center. Innovative and tailored LDKT educational strategies for black patients are needed to help reduce racial disparities in LDKT.

Abstract
BACKGROUND AND OBJECTIVES Disparities in kidney transplantation remain; one mechanism for disparities in access to transplantation (ATT) may be patient-perceived concerns about pursuing transplantation. This study sought to characterize prevalence of patient-perceived concerns, explore interrelationships between concerns, determine patient characteristics associated with concerns, and assess the effect of concerns on ATT. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Prevalences of 12 patient-perceived concerns about pursuing transplantation were determined among 348 adults who recently initiated dialysis, recruited from 26 free-standing dialysis centers around Baltimore, Maryland (January 2009-March 2012). Using variable reduction techniques, concerns were clustered into two categories (health-related and psychosocial) and quantified with scale scores. Associations between patient characteristics and concerns were estimated using modified Poisson regression. Associations between concerns and ATT were estimated using Cox models. RESULTS The most frequently cited patient-perceived concerns were that participants felt they were doing fine on dialysis (68.4%) and felt uncomfortable asking someone to donate a kidney (29.9%). Older age was independently associated with having high health-related (adjusted relative risk, 1.35 [95% confidence interval, 1.20 to 1.51], for every 5 years older for those ≥ 60 years) or psychosocial (1.15 [1.00 to 1.31], for every 5 years older for those aged ≥ 60 years) concerns, as was being a woman (1.72 [1.21 to 2.43] and 1.55 [1.09 to 2.20]), having less education (1.59 [1.08 to 2.35] and 1.77 [1.17 to 2.68], comparing postsecondary education to grade school or less), and having more comorbidities (1.18 [1.08 to 1.30] and 1.18 [1.07 to 1.29], per one comorbidity increase). Having never seen a nephrologist before dialysis initiation was associated with high psychosocial concerns (1.48 [1.01 to 2.18]). Those with high health-related (0.37 [0.16 to 0.87]) or psychosocial (0.47 [0.23 to 0.95]) concerns were less likely to achieve ATT (median follow-up time 2.2 years; interquartile range, 1.6-3.2). CONCLUSIONS Patient-perceived concerns about pursuing kidney transplantation are highly prevalent, particularly among older adults and women. Reducing these concerns may help decrease disparities in ATT.

Abstract
Pulmonary hypertension (PH) is a significant complication of sarcoidosis, occurring in approximately 6 to > 20% of cases, and markedly increases mortality among these patients. The clinician should exercise a high index of suspicion for sarcoidosis-associated PH (SAPH) given the nonspecific symptomatology and the limitations of echocardiography in this patient population. The pathophysiology of PH in sarcoidosis is complex and multifactorial. Importantly, there are inherent differences in the pathogenesis of SAPH compared with idiopathic pulmonary arterial hypertension, making the optimal management of SAPH controversial. In this article, we review the epidemiology, diagnosis, prognosis, and treatment considerations for SAPH. Lung transplantation (LT) is a viable therapeutic option for sarcoid patients with severe pulmonary fibrocystic sarcoidosis or SAPH refractory to medical therapy. We discuss the role for LT in patients with sarcoidosis, review the global experience with LT in this population, and discuss indications and contraindications to LT.

Significant racial differences in the key factors associated with early graft loss in kidney transplant recipients. Am J Nephrol 2014; 40:19-28. [PMID: 24969370 DOI: 10.1159/000363393] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2014] [Accepted: 05/02/2014] [Indexed: 11/19/2022]
Abstract
BACKGROUND There is continued and significant debate regarding the salient etiologies associated with graft loss and racial disparities in kidney transplant recipients. METHODS This was a longitudinal cohort study of all adult kidney transplant recipients, comparing patients with early graft loss (<5 years) to those with graft longevity (surviving graft with at least 5 years of follow-up) across racial cohorts [African-American (AA) and non-AA] to discern risk factors. RESULTS 524 patients were included, 55% AA, 151 with early graft loss (29%) and 373 with graft longevity (71%). Consistent within both races, early graft loss was significantly associated with disability income [adjusted odds ratio (AOR) 2.2, 95% CI 1.1-4.5], Kidney Donor Risk Index (AOR 3.2, 1.4-7.5), rehospitalization (AOR 2.1, 1.0-4.4) and acute rejection (AOR 4.4, 1.7-11.6). Unique risk factors in AAs included Medicare-only insurance (AOR 8.0, 2.3-28) and BK infection (AOR 5.6, 1.3-25). Unique protective factors in AAs included cardiovascular risk factor control: AAs with a mean systolic blood pressure <150 mm Hg had 80% lower risk of early graft loss (AOR 0.2, 0.1-0.7), while low-density lipoprotein <100 mg/dl (AOR 0.4, 0.2-0.8), triglycerides <150 mg/dl (AOR 0.4, 0.2-1.0) and hemoglobin A1C <7% (AOR 0.2, 0.1-0.6) were also protective against early graft loss in AA, but not in non-AA recipients. CONCLUSIONS AA recipients have a number of unique risk factors for early graft loss, suggesting that controlling cardiovascular comorbidities may be an important mechanism to reduce racial disparities in kidney transplantation.

Abstract
Context Barriers to kidney transplant for African Americans are well documented in the literature. Little information on ownership of information and communication technology and use of such technology in transplant populations has been published. Objective To characterize racial differences related to ownership and use of information and communication technology in kidney transplant patients. Design A single-center, cross-sectional survey study. Setting An urban Midwestern transplant center. Participants 78 pretransplant patients and 177 transplant recipients. Main Outcomes Measures The survey consisted of 6 demographic questions, 3 disease-related questions, and 9 technology-related questions. Dichotomous (yes/no) and Likert-scale items were the basis for the survey. Results Cell phone use was high and comparable between groups (94% in African Americans, 90% in whites, P = .22). A vast majority (75% of African Americans and 74% of whites) reported being “comfortable” sending and receiving text messages. Computer ownership (94.3% vs 79.3%) and Internet access (97.7% vs 80.7%) were greater among whites than African Americans (both P < .01). Fewer African Americans were frequent users of the Internet (27.1% vs 56.3%) and e-mail (61.6% vs 79.3%) than whites (both P < .01). More African Americans than whites preferred education in a classroom setting (77% vs 60%; P < .005) and educational DVDs (66% vs 46%; P < .002). Conclusion The use of cell phone technology and text messaging was ubiquitous and comparable between groups, but computer and Internet access and frequency of use were not. Reaching out to the African American community may best be accomplished by using cell phone/text messaging as opposed to Internet-based platforms.

Abstract
Transplantation is the favored therapy for patients with end-stage renal disease (ESRD). Unfortunately, demand for available organs far outpaces the supply. African Americans are disproportionately affected by the ever-widening gap between organ supply and demand. Additionally, structural, biological, and social factors contribute to feelings of unease some African Americans may feel regarding living donor transplant (LDT). The present research examines the relationship between trust in health care and attitudes toward LDT among African American ESRD patients. We hypothesized that lower trust in health care would be significantly associated with negative attitudes toward LDT, and that this relationship would be moderated by patient attitudes toward dialysis. Data were collected from August 2011 to April 2012 as part of a larger study. Measures included trust (of doctors, racial equity of treatment, and hospitals) and attitudes toward both LDT and dialysis. Bivariate analysis revealed that trust in one's doctor, hospital, and in racial equity in health care was significantly correlated with attitudes toward LDT (r = 0.265; r = 0.131; and r = 0.202, respectively). Additionally, attitudes toward dialysis moderated the relationships between Trust in Doctors/Attitudes toward LDT and Trust in Racial equity of treatment/Attitudes toward LDT. Findings suggest a strong relationship between trust in health care and attitudes toward LDT. These findings also shed light on how dialysis experiences are related to the relationship between trust in health care and attitudes toward LDT.

Abstract
Few studies have compared determinants of live donor kidney transplantation (LDKT) across all major US racial-ethnic groups. We compared determinants of racial-ethnic differences in LDKT among 208 736 patients who initiated treatment for end-stage kidney disease during 2005-2008. We performed proportional hazards and bootstrap analyses to estimate differences in LDKT attributable to sociodemographic and clinical factors. Mean LDKT rates were lowest among blacks (1.19 per 100 person-years [95% CI: 1.12-1.26]), American Indians/Alaska Natives-AI/ANs (1.40 [1.06-1.84]) and Pacific Islanders (1.10 [0.78-1.84]), intermediate among Hispanics (2.53 [2.39-2.67]) and Asians (3.89 [3.51-4.32]), and highest among whites (6.46 [6.31-6.61]). Compared with whites, the largest proportion of the disparity among blacks (20%) and AI/ANs (29%) was attributed to measures of predialysis care, while the largest proportion among Hispanics (14%) was attributed to health insurance coverage. Contextual poverty accounted for 16%, 4%, 18%, and 6% of the disparity among blacks, Hispanics, AI/ANs and Pacific Islanders but none of the disparity among Asians. In the United States, significant disparities in rates of LDKT persist, but determinants of these disparities vary by race-ethnicity. Efforts to expand preESKD insurance coverage, to improve access to high-quality predialysis care and to overcome socioeconomic barriers are important targets for addressing disparities in LDKT.

Abstract
Renal transplantation is the gold standard treatment for patients with end-stage renal disease and is associated with several advantages over dialysis, including increased quality of life, reduced morbidity and mortality, and lower healthcare costs. Barring the constraints of a limited organ supply, the goals of the patient care should focus on attaining renal transplantation while minimizing, or even eliminating, time spent on dialysis. Disparities in access to renal transplantation between African Americans and Caucasians have been extensively documented, with African Americans having significantly poorer access. There is a growing corpus of literature examining the determinants of reduced access among other racial ethnic minority groups, including Hispanics. These determinants include patient and physician preference, socioeconomic status, insurance type, patient education, and immunologic factors. We review these determinants in access to renal transplantation in the United States among all races and ethnicities.

Abstract
In the United States, racial-ethnic minorities experience disproportionately high rates of ESRD, but they are substantially less likely to receive living donor kidney transplants (LDKT) compared with their majority counterparts. Minorities may encounter barriers to LDKT at several steps along the path to receiving it, including consideration, pursuit, completion of LDKT, and the post-LDKT experience. These barriers operate at different levels related to potential recipients and donors, health care providers, health system structures, and communities. In this review, we present a conceptual framework describing various barriers that minorities face along the path to receiving LDKT. We also highlight promising recent and current initiatives to address these barriers, as well as gaps in initiatives, which may guide future interventions to reduce racial-ethnic disparities in LDKT.

Abstract
Beginning January 1, 2000, Medicare effectively extended its coverage of immunosuppression medications from 3 years to lifetime for patients eligible for Medicare on the basis of age or disability status. We examined the impact of this policy on racial disparities in kidney transplant outcomes at 5 years. Using data from the US Renal Data System, we identified cohorts of Medicare-insured kidney transplant recipients according to patient characteristics defining eligibility for lifetime immunosuppression coverage according to the year 2000 policy. We compared racial disparities in graft survival among those eligible for lifetime coverage with the Kaplan-Meier method. We modeled adjusted associations of patient race, patient income, benefits eligibility category and policy exposure with graft loss by multivariable Cox's regression. The racial disparity in graft survival between African American and non-African American among transplant recipients eligible for the lifetime benefit persisted. The graft survival disparity between high- and low-income African American recipients was insignificantly reduced among those eligible for the lifetime benefit. The results of the study suggest that insurance coverage of medication did not eliminate or reduce the racial disparity in graft survival.

Abstract
BACKGROUND Although end-stage kidney disease in African Americans (AAs) is four times greater than in whites, AAs are less than one half as likely to undergo kidney transplantation (KT). This racial disparity has been found even after controlling for clinical factors such as comorbid conditions, dialysis vintage and type, and availability of potential living donors. Therefore, studying nonmedical factors is critical to understanding disparities in KT. METHODS We conducted a longitudinal cohort study with 127 AA and white patients with end-stage kidney disease undergoing evaluation for KT (December 2006 to July 2007) to determine whether, after controlling for medical factors, differences in time to acceptance for transplant is explained by patients' cultural factors (e.g., perceived racism and discrimination, medical mistrust, religious objections to living donor KT), psychosocial characteristics (e.g., social support, anxiety, depression), or transplant knowledge. Participants completed two telephone interviews (shortly after initiation of transplant evaluation and after being accepted or found ineligible for transplant). RESULTS Results indicated that AA patients reported higher levels of the cultural factors than did whites. We found no differences in comorbidity or availability of potential living donors. AAs took significantly longer to get accepted for transplant than did whites (hazard ratio=1.49, P=0.005). After adjustment for demographic, psychosocial, and cultural factors, the association of race with longer time for listing was no longer significant. CONCLUSIONS We suggest that interventions to address racial disparities in KT incorporate key nonmedical risk factors in patients.

Abstract
Despite a substantially lower rate of live donor kidney transplantation among Black Americans compared to White Americans, there are few systematic efforts to reduce this racial disparity. This paper describes the rationale and design of a randomized controlled trial evaluating the comparative effectiveness of three different educational interventions for increasing live donor kidney transplantation in Black Americans. This trial is a single-site, urn-randomized controlled trial with a planned enrollment of 180 Black Americans awaiting kidney transplantation. Patients are randomized to receive transplant education in one of three education conditions: through group education at their homes (e.g., House Calls), or through group (Group-Based) or individual education (Individual Counseling) in the transplant center. The primary outcome of the trial is the occurrence of a live donor kidney transplant, with secondary outcomes including living donor inquiries and evaluations as well as changes in patient live donor kidney transplantation readiness, willingness, knowledge, and concerns. Sex, age, dialysis status, and quality of life are evaluated as moderating factors. Findings from this clinical trial have the potential to inform strategies for reducing racial disparities in live donor kidney transplantation. Similar trials have been developed recently to broaden the evaluation of House Calls as an innovative disparity-reducing intervention in kidney transplantation.

Abstract
BACKGROUND Preemptive transplantation is associated with better survival and transplant outcomes than transplantation after dialysis has been started. The purpose of this study is to examine associations between candidate characteristics, likelihood of preemptive transplant, candidate survival and renal function (RF) at the time of listing. METHODS We looked at 57 677 solitary renal transplant candidates from the Scientific Registry of Transplant Recipients database listed prior to dialysis from 2000 to 2009. Using multivariable models, we measured associations between candidate characteristics, likelihood of preemptive transplantation, candidate survival and RF at listing. RESULTS Candidates with higher RF at listing were more likely to be male, Caucasian, diabetic, be a prior transplant recipient and have more education. Higher RF at listing was strongly associated with greater likelihood of receipt of preemptive transplant [adjusted odds ratio = 1.45, 95% confidence interval (CI) 1.38-1.51] and conferred a significant survival advantage [adjusted hazards ratio = 0.84, 95% CI 0.79-0.89, per 5 mL/min/1.73 m(2)]. CONCLUSIONS Patient characteristics associated with higher RF at listing suggest differences in access to care. Given that higher RF at the time of listing was also significantly associated with greater likelihood of preemptive transplantation and better survival prior to transplantation, our results suggest that listing at higher levels of RF may improve transplant candidate outcomes.

Abstract
PURPOSE OF REVIEW High prevalence of comorbidities such as diabetes, hypertension, obesity, hepatitis B and C, in minority groups, results in racial minorities being disproportionally represented on transplant waiting lists. Organ transplantation positively impacts patient survival but greater access is limited by a severe donor shortage. RECENT FINDINGS Unfortunately, minority groups also suffer from disparities in deceased and living donation. African-Americans comprise 12.9% of the population and 34% of the kidney transplant waiting list but only 13.8% of deceased donors. Barriers to minority deceased donation include: decreased awareness of transplantation, religious or cultural distrust of the medical community, fear of medical abandonment and fear of racism. Furthermore, African-Americans comprise only 11.8% of living donors. Barriers to minority living donation include: unwillingness to donate, medical comorbid conditions, trust or fear of medical community, loss to follow-up, poor coping mechanisms, financial concerns, reluctance to ask family members and friends, fear of surgery, and lack of awareness about living donor kidney transplantation. SUMMARY Transplant center-based education classes significantly and positively impact African-American concerns and beliefs surrounding living donation. Community and national strategies utilizing culturally sensitive communication and interventions can ameliorate disparities and improve access to transplantation.

Abstract
African Americans are overrepresented on the organ transplant waiting list because they are disproportionately impacted by certain health conditions that potentially warrant a life-saving transplant. While the African American need for transplantation is considerably high, organ and tissue donation rates are comparatively low, resulting in African Americans spending more than twice the amount of time on the national transplant waiting list as compared to people of other racial/ethnic backgrounds. There are a multitude of factors that contribute to the reluctance expressed by African Americans with respect to organ donation. This study proposes the use of an adaptation of the Organ Donation Model to explore the ways in which knowledge, trust in the donation/allocation process, and religious beliefs impact African American donation decision making. Bivariate and path analyses demonstrated that alignment with religious beliefs was the greatest driving factor with respect to attitudes towards donation; attitudes were significantly associated with donation intentions; and knowledge is directly associated with intentions to serve as a potential deceased organ donor. The significance of these variables speaks to the importance of their inclusion in a model that focuses on the African American population and offers new direction for more effective donation education efforts.

Abstract
BACKGROUND AND OBJECTIVES Many factors have been shown to be associated with ESRD patient placement on the waiting list and receipt of kidney transplantation. Our study aim was to evaluate factors and assess the interplay of patient characteristics associated with progression to transplantation in a large cohort of referred patients from a single institution. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We examined 3029 consecutive adult patients referred for transplantation from 2003 to 2008. Uni- and multivariable logistic models were used to assess factors associated with progress to transplantation including receipt of evaluations, waiting list placement, and receipt of a transplant. RESULTS A total of 56%, 27%, and 17% of referred patients were evaluated, were placed on the waiting list, and received a transplant over the study period, respectively. Older age, lower median income, and noncommercial insurance were associated with decreased likelihood to ascend steps to receive a transplant. There was no difference in the proportion of evaluations between African Americans (57%) and Caucasians (56%). Age-adjusted differences in waiting list placement by race were attenuated with further adjustment for income and insurance. There was no difference in the likelihood of waiting list placement between African Americans and Caucasians with commercial insurance. CONCLUSIONS Race/ethnicity, age, insurance status, and income are predominant factors associated with patient progress to transplantation. Disparities by race/ethnicity may be largely explained by insurance status and income, potentially suggesting that variable insurance coverage exacerbates disparities in access to transplantation in the ESRD population, despite Medicare entitlement.

Abstract
Success of renal transplantation, as a viable alternative to dialysis, has been tempered by long-standing racial disparities. Ethnic minorities have less access to transplantation, are less likely to be listed for transplantation, and experience a higher rate of graft failure. Reasons for the existing racial disparities at various stages of the transplantation process are complex and multi-factorial. They include a combination of behavioral, social, environmental, and occupational factors, as well as potential intended or unintended discrimination within the healthcare system. Immunologic factors such as human leukocyte antigen matching, composition of the organ donor pool, and patient immune response, all of which affect post-transplantation graft rejection rates and patient survival, also contribute to health disparities between ethnic groups.

Abstract
BACKGROUND Despite the known benefits of preemptive kidney transplantation, its rate of use remains low. OBJECTIVE To determine whether focused, comprehensive education provided at a clinic for patients with chronic kidney disease would improve the rate of preemptive transplantation and transplant wait times. METHODS A retrospective cohort study design was used. The rate of preemptive transplantation and transplant wait times were compared between patients with end-stage renal disease who had been followed in a chronic kidney disease clinic for more than 3 months and patients with end-stage kidney disease who had not been followed for chronic kidney disease care during the same period. RESULTS More African Americans than others had initiated dialysis without having had previous care for chronic kidney disease. The rate of preemptive transplantation was 24% for patients followed in the clinic. For those patients without living donor options, mean transplant referral time was significantly different between patients followed at the clinic and patients who were not: 234 (SD, 392) days before dialysis was started versus 161 (SD, 525) days after dialysis was started (P = .01). CONCLUSION A chronic kidney disease clinic can influence rates of preemptive kidney transplantation and transplantation referral times.

Abstract
BACKGROUND AND PURPOSE The influence of African-American ethnicity on outcomes of kidney transplant recipients subjected to early steroid withdrawal remains controversial. Recent studies that suggest no higher risk among African Americans may be biased by recruitment of relatively small number of African Americans or by patient selection. We compared outcomes of African Americans to non-African Americans in a center in which early steroid withdrawal has become the standard of practice. METHODS This was a single-center prospective study of 133 consecutive patients receiving primary kidney transplants between January 2006 and December 2008, followed for >or=3 months, and managed with a similar immunosuppression regimen that included induction antibody therapy, tacrolimus, mycophenolate mofetil, and withdrawal of steroids on postoperative day 5. Acute rejection and other outcomes were compared in African-American patients (n = 55) and compared with those of non-African-American patients (n = 78). RESULTS During the first 12 months after early steroid withdrawal, African-American patients experienced a significantly higher cumulative incidence of acute rejection than non-African Americans (23.6% vs 7.7%; P = .020). Using multivariate logistic regression, ethnicity (odds ratio 3.33; P = .047) and HLA mismatch (odds ratio 1.44; P = .041) were significantly correlated with acute rejection independent of recipient age, gender, historical peak panel reactive antibody level (PRA) or PRA at time of transplant, time on dialysis, or donor source. CONCLUSIONS African Americans are at increased risk of acute rejection after early steroid withdrawal, particularly when they receive kidneys from poorly matched donors.

Abstract
Numerous studies report a strong association between pretransplant end-stage renal disease (ESRD) duration and diminished transplant outcomes. However, cumulative waiting time may reflect distinct phases and processes related to patients' physiological condition as well as pre-existing morbidity and access to care. The relative impact of pre- and postlisting ESRD durations on transplant outcomes is unknown. We examined the impact of these intervals from a national cohort of kidney transplant recipients from 1999 to 2008 (n = 112,249). Primary factors explaining prelisting ESRD duration were insurance and race, while primary factors explaining postlisting ESRD duration were blood type, PRA% and variation between centers. Extended time from ESRD to waitlisting had significant dose-response association with overall graft loss (AHR = 1.26 for deceased donors [DD], AHR = 1.32 for living donors [LD], p values < 0.001). Contrarily, time from waitlisting (after ESRD) to transplantation had negligible effects (p = 0.10[DD], p = 0.57[LD]). There were significant associations between pre- and postlisting ESRD time with posttransplant patient survival, however prelisting time had over sixfold greater effect. Prelisting ESRD time predominately explains the association of waiting time with transplant outcomes suggesting that factors associated with this interval should be prioritized for interventions and allocation policy. The degree to which the effect of prelisting ESRD time is a proxy for comorbid conditions, socioeconomic status or access to care requires further study.

Abstract
Background Despite the known benefits of preemptive kidney transplantation, its rate of use remains low. Objective To determine whether focused, comprehensive education provided at a clinic for patients with chronic kidney disease would improve the rate of preemptive transplantation and transplant wait times. Methods A retrospective cohort study design was used. The rate of preemptive transplantation and transplant wait times were compared between patients with end-stage renal disease who had been followed in a chronic kidney disease clinic for more than 3 months and patients with end-stage kidney disease who had not been followed for chronic kidney disease care during the same period. Results More African Americans than others had initiated dialysis without having had previous care for chronic kidney disease. The rate of preemptive transplantation was 24% for patients followed in the clinic. For those patients without living donor options, mean transplant referral time was significantly different between patients followed at the clinic and patients who were not: 234 (SD, 392) days before dialysis was started versus 161 (SD, 525) days after dialysis was started ( P= .01).

Abstract
The barriers to live donor transplantation are poorly understood. We performed a prospective cohort study of individuals undergoing renal transplant evaluation. Participants completed a questionnaire that assessed clinical characteristics as well as knowledge and beliefs about transplantation. A participant satisfied the primary outcome if anyone contacted the transplant center to be considered as a live donor for that participant. The final cohort comprised 203 transplant candidates, among whom 80 (39.4%) had a potential donor contact the center and 19 (9.4%) underwent live donor transplantation. In multivariable logistic regression, younger candidates (OR 1.65 per 10 fewer years, p < 0.01) and those with annual income >or=US$ 15 000 (OR 4.22, p = 0.03) were more likely to attract a potential live donor. Greater self-efficacy, a measure of the participant's belief in his or her ability to attract a donor, was a predictor of having a potential live donor contact the center (OR 2.73 per point, p < 0.01), while knowledge was not (p = 0.56). The lack of association between knowledge and having a potential donor suggests that more intensive education of transplant candidates will not increase live donor transplantation. On the other hand, self-efficacy may be an important target in designing interventions to help candidates find live donors.

Abstract
Despite universal payer coverage with Medicare, sociodemographic disparities confound the care of patients with renal failure. We sought to determine whether adults who realize access to kidney transplantation suffer inequities in the utilization of live donor renal transplantation (LDRT). We identified adults undergoing primary renal transplantation in 2004-2006 from the United Network for Organ Sharing (UNOS). We modeled receipt of live versus deceased donor renal transplant on multilevel multivariate models that examined recipient, center and UNOS region-specific covariates. Among 41 090 adult recipients identified, 39% underwent LDRT. On multivariate analysis, older recipients (OR 0.62, 95% CI 0.56-0.68 for 50-59 year-olds vs. 18-39 year-old recipients), those of African American ethnicity (OR 0.54, 95% CI 0.50-0.59 vs. whites) and of lower socioeconomic status (OR 0.72, 95% CI 0.67-0.79 for high school-educated vs. college-educated recipients; OR 0.78, 95% CI 0.71-0.87 for lowest vs. highest income quartile) had lower odds of LDRT. These characteristics accounted for 14.2% of the variation in LDRT, more than recipient clinical variables, transplant center characteristics and UNOS region level variation. We identified significant racial and socioeconomic disparities in the utilization of LDRT. Educational initiatives and dissemination of processes that enable increased utilization of LDRT may address these disparities.

Abstract
BACKGROUND African Americans (AA) and women are less likely to receive a live kidney donor (LKD) transplant than Caucasians or men. Reasons for non-donation are poorly understood. METHODS A retrospective review of 541 unsuccessful LKD was performed to explore reasons for non-donation and to assess for racial and/or gender differences. RESULTS We identified 138 AA and 385 Caucasian subjects who volunteered but did not successfully donate. Females (58.2%) were more likely to be excluded than males due to reduced renal function (glomerular filtration rate < 85 mL/min, 7.9% vs. 0.9%, p < 0.0001) or failure to complete the evaluation (6.4% vs. 1.8%, p = 0.01). AA were more commonly excluded due to obesity (body mass index >or= 32 kg/m(2); 30.4% AA vs. 16.6% Caucasian, p = 0.0005) or failure to complete the evaluation (12.3% AA vs. 1.8% Caucasian, p < 0.0001) whereas Caucasians were more often excluded due to kidney stones (1.5% AA vs. 7.3% Caucasian, p = 0.01). CONCLUSIONS Significantly different reasons for exclusion of LKD exist between potential Caucasian and AA LKD, particularly among women. Among the differences that we observed are potentially modifiable barriers to donation including obesity and failure to complete the donor evaluation. A further understanding of these barriers may help point to strategies for more effective recruitment and successful LKD.

Abstract
BACKGROUND No national data exist regarding racial/ethnic differences in the use of interventions for patients at the end of life. OBJECTIVES To test whether among 3 cohorts of hospitalized seriously ill veterans with cancer, noncancer or dementia the use of common life-sustaining treatments differed significantly by race/ethnicity. DESIGN Retrospective cohort study during fiscal years 1991-2002. PATIENTS Hospitalized veterans >55 years, defined clinically as at high-risk for 6-month mortality, not by decedent data. MEASUREMENTS Utilization patterns by race/ethnicity for 5 life-sustaining therapies. Logistic regression models evaluated differences among Caucasians, African Americans and Hispanics, controlling for age, disease severity and clustering of patients within Veterans Affairs (VA) medical centers. RESULTS Among 166,059 veterans, both differences and commonalities across diagnostic cohorts were found. African Americans received more or the same amount of end-of-life treatments across disease cohorts, except for less resuscitation [OR = 0.84 (0.77-0.92), p = 0.002] and mechanical ventilation [OR = 0.89 (0.85-0.94), p < or = 0.0001] in noncancer patients. Hispanics were 36% (cancer) to 55% (noncancer) to 88% (dementia) more likely to receive transfusions than Caucasians (p < 0.0001). They received similar rates as Caucasians for all other interventions in all other groups, except for 161% higher likelihood for mechanical ventilation in patients with dementia. Increased end-of-life treatments for both minority groups were most pronounced in the dementia cohort. Differences demonstrated a strong interaction with the disease cohort. CONCLUSIONS Differences in level of end-of-life treatments were disease specific and bidirectional for African Americans. In the absence of generally accepted, evidence-based standards for end-of-life care, these differences may or may not constitute disparities.

Abstract
Although the majority of deceased-donor kidneys are donated after brain death, increased recovery of kidneys donated after cardiac death could reduce the organ shortage and is now a national priority. Racial disparities in donations after brain death have been well described for renal transplantation, but it is unknown whether similar disparities occur in donations after cardiac death. In this study, outcomes of adult deceased-donor renal transplant recipients included in the United Network for Organ Sharing database (1993 through 2006) were analyzed. Among black recipients of kidneys obtained after cardiac death, those who received kidneys from black donors had better long-term graft and patient survival than those who received kidneys from white donors. In addition, compared with standard-criteria kidneys from white donors after brain death, kidneys from black donors after cardiac death conferred a 70% reduction in the risk for graft loss (adjusted hazard ratio 0.30; 95% confidence interval 0.14 to 0.65; P = 0.002) and a 59% reduction in risk for death (adjusted hazard ratio 0.41; 95% confidence interval 0.2 to 0.87; P = 0.02) among black recipients. These findings suggest that kidneys obtained from black donors after cardiac death may afford the best long-term survival for black recipients.

Abstract
Compared with white individuals, black individuals have a significantly higher risk for death in the general population but seem to have a survival advantage in the ESRD population. Data on the relationship of race to survival in early stages of chronic kidney disease (CKD) are inconsistent. This study evaluated racial differences in mortality among the adult participants of the Third National Health and Nutrition Examination Survey, a population-based survey of community-dwelling individuals. CKD was defined either by an estimated GFR < 60 ml/min per 1.73 m2 or by the presence of albuminuria, and this status was determined for 14,611 individuals, 2892 of whom were found to have CKD. Adjusting for age,gender, and race, risk for all-cause mortality among individuals with CKD was more than double that of individuals with normal renal function. In the subgroup with CKD, adjusting for age and gender,black individuals had a significantly higher risk for death, and this risk was modified by age;specifically, black individuals who were younger than 65 yr were 78% more likely to die than white individuals, whereas no significant differences in mortality were observed among individuals who were > or = 65 yr of age. Further adjustment for cardiovascular risk factors and CKD stage did not materially change the results, but the hazard ratios were significantly attenuated after adjustment for socioeconomic factors. In conclusion, these data demonstrate racial/ethnic disparities in mortality among individuals with CKD. This higher risk for death in early stages of CKD may explain the apparent survival advantage observed among black individuals who live long enough to reach stage 5 CKD.

Abstract
OBJECTIVE To explore the association between different types of knowledge related to donation and transplantation and the expression of donation intentions via one's driver's license, a donor card, or sharing one's wishes with family. METHODS Cross-sectional data were gathered via self-administered questionnaire from 425 Black adults, age 18 years and older who were recruited from nine churches in a large metropolitan area in the southeast United States. RESULTS Results indicate that knowledge of the allocation system and experiential knowledge of a transplant recipient are associated with donation intentions after controlling for age, gender, and highest level of education. However, the following types of knowledge were unrelated to donation intentions: donation-related statistics (including an understanding of African Americans' overrepresentation among those in need), the donation process, the process for determining medical suitability, and religious institutions' support for donation. CONCLUSIONS Findings suggest that the relationship between donation-related knowledge and donation intentions is complex and may depend on the specific type of knowledge being measured. PRACTICE IMPLICATIONS Knowledge of the allocation system and experiential knowledge of a recipient may be critical aspects of the donation decision-making process. Research findings suggest the need for an educational approach that seeks to improve the specific types of knowledge that are most strongly associated with donation intentions.

Abstract
The survival advantage of kidney transplantation extends to many high-risk ESRD patients; however, numerous factors ultimately determine which patients are evaluated and listed for the procedure. Broad goals of patient evaluation comprise identifying patients who will benefit from transplantation and excluding patients who might be placed at risk. There is limited data detailing whether current access limitations and screening strategies have achieved the goal of listing the most appropriate patients. The study estimated the life expectancy of adult patients in the United States prior to transplantation with ESRD onset from 1995 to 2003. Factors associated with transplant listing were examined based on patient prognosis after ESRD. Approximately one-third of patients listed for transplantation within 1 year of ESRD had </=5-year life expectancy on dialysis. In contrast, one-third of patients not listed had >5-year life expectancy. The number of patients not listed with 'good' prognosis was significantly higher than those listed with 'poor' prognosis (134 382 vs. 16 807, respectively). Age, race, gender, insurance coverage and body mass index (BMI) were associated with likelihood for listing with 'poor' prognosis and not listing with 'good' prognosis. Over the past decade, many ESRD patients viable for transplantation have not listed for transplantation while higher-risk patients have listed rapidly.
