Non-medical factors influencing access to renal transplantation
International Urology and Nephrology, 2009
Considering the scarcity of available donor kidneys and the increasing number of patients with end-stage renal disease (ESRD) who would potentially benefit from renal transplantation, objective and equitable patient selection and equitable access to renal transplantation bear substantial importance. Inequalities in access to renal transplantation have been extensively documented over the last 2 decades with regard to age, gender, ethnicity, socioeconomic and psycho-social factors. In this paper we review a wide spectrum of social, patient and system-related factors along the transplantation process that may be associated with disparities, and we aim to describe the complex interrelationship between these factors that might influence treatment decisions by patients and health-care professionals. Understanding potentially modifiable barriers to kidney transplantation may allow designing targeted interventions in order to guarantee fair recipient selection and equal access to renal transplantation.
Trends in kidney transplantation rates and disparities
Journal of the National Medical Association
To examine the likelihood of transplantation and trends over time among persons with end-stage renal disease (ESRD) in Wisconsin. We examined the influence of patient- and community-level characteristics on the rate of kidney transplantation in Wisconsin among 22,387 patients diagnosed with ESRD between January 1, 1982 and October 30, 2005. We grouped patients by the year of ESRD onset in order to model the change in transplantation rates over time. After multivariate adjustment, all other racial groups were significantly less likely to be transplanted compared with whites, and the racial disparity increased over calendar time. Older patients were less likely to be transplanted in all periods. Higher community income and education level and a greater distance from patients' residence to the nearest dialysis center significantly increased the likelihood of transplantation. Males also had a significantly higher rate of transplantation than females. These results demonstrate a grow...
Social Determinants of Health and Chronic Kidney Disease
Cureus, 2020
In the United States, chronic kidney disease (CKD) remains a concern to the health of 37 million adults. Prevention is key to combatting this disease before it is able to progress into its advanced stages or endstage renal disease (ESRD). Awareness of the clinical early detection of CKD is important for healthcare providers, but a look at the causes of this disease can provide for greater evaluation of the patient's risks. Understanding of social determinants of health (SDOH), the non-clinical aspects of a patient's life that affect disease onset and progression, and its effects on CKD and ESRD should be greater emphasized in the primary care field. Population groups living with relatively poorer SDOH are disproportionally affected by CKD and ESRD. Although political change is out of the scope of the primary care health provider, efforts in combatting poor social determinants can provide for better outcomes for at-risk or diagnosed patients. Education and screening are two suggestions brought up in literature for tackling SDOH, specifically in the primary care settings most applicable to CKD.
Role of Socioeconomic Status in Kidney Transplant Outcome
Clinical Journal of the American Society of Nephrology, 2006
There is controversy regarding the influence of genetic versus environmental factors on kidney transplant outcome in minority groups. The goal of this project was to evaluate the role of certain socioeconomic factors in allograft and recipient survival. Graft and recipient survival data from the United States Renal Data System were analyzed using Cox modeling with primary variables of interest, including recipient education level, citizenship, and primary source of pay for medical service. College (hazard ratio [HR] 0.93, P < 0.005) and postcollege education (HR 0.85, P < 0.005) improved graft outcome in the whole group and in patients of white race. Similar trends were observed for recipient survival (HR 0.9, P < 0.005 for college; HR 0.88, P ؍ 0.09 for postcollege education) in the whole population and in white patients. Resident aliens had a significantly better graft outcome in the entire patient population (HR 0.81, P < 0.001) and in white patients in subgroup analysis (HR 0.823, P < 0.001) compared with US citizens. A similar effect was observed for recipient survival. Using Medicare as a reference group, there is a statistically significant benefit to graft survival from having private insurance in the whole group (HR 0.87, P < 0.001) and in the black (HR 0.8, P < 0.001) and the white (HR 0.89, P < 0.001) subgroups; a similar effect of private insurance is observed on recipient survival in the entire group of patients and across racial groups. Recipients with higher education level, resident aliens, and patients with private insurance have an advantage in the graft and recipient outcomes independent of racial differences.
Nephrology, dialysis, transplantation : official publication of the European Dialysis and Transplant Association - European Renal Association, 2015
It is unclear whether a social gradient in health outcomes exists for people with moderate-to-severe chronic kidney disease (CKD). We critically review the literature for evidence of social gradients in health and investigate the 'suitability' of statistical analyses in the primary studies. In this equity-focused systematic review among adults with moderate-to-severe CKD, factors of disadvantage included gender, race/ethnicity, religion, education, socio-economic status or social capital, occupation and place of residence. Outcomes included access to healthcare, kidney disease progression, cardiovascular events, all-cause mortality and suitability of analyses. Twenty-four studies in the pre-dialysis population and 34 in the dialysis population representing 8.9 million people from 10 countries were included. In methodologically suitable studies among pre-dialysis patients, a significant social gradient was observed in access to healthcare for those with no health insurance an...
Disparities in Kidney Transplant Outcomes: A Review
Seminars in Nephrology, 2010
Sociocultural and socioeconomic disparities in graft survival, graft function, and patient survival in adult kidney transplant recipients are reviewed. Studies consistently document worse outcomes for black patients, patients with low income, and patients with less education, whereas better outcomes are reported in Hispanic and Asian kidney transplant recipients. However, the distinct roles of racial/ethnic versus socioeconomic factors remain unclear. Attention to potential pathways contributing to disparities has been limited to immunologic and nonimmunologic factors, for which the mechanisms have yet to be fully illuminated. Interventions to reduce disparities have focused on modifying immunosuppressant regimens. Modifying access to care and health care funding policies for immunosuppressive medication coverage also are discussed. The implementation of culturally sensitive approaches to the care of transplant candidates and recipients is promising. Future research is needed to examine the mechanisms contributing to disparities in graft survival and ultimately to intervene effectively.
Neighborhood Poverty and Racial Disparities in Kidney Transplant Waitlisting
Journal of the American Society of Nephrology, 2009
Racial disparities persist in the United States renal transplantation process. Previous studies suggest that the distance between a patient's residence and the transplant facility may associate with disparities in transplant waitlisting. We examined this possibility in a cohort study using data for incident, adult ESRD patients (1998 to 2002) from the ESRD Network 6, which includes Georgia, North Carolina, and South Carolina. We linked data with the United Network for Organ Sharing (UNOS) transplant registry through 2005 and with the 2000 U.S. Census geographic data. Of the 35,346 subjects included in the analysis, 12% were waitlisted, 57% were black, 50% were men, 20% were impoverished, 45% had diabetes as the primary etiology of ESRD, and 73% had two or more comorbidities. The median distance from patient residence to the nearest transplant center was 48 mi. After controlling for multiple covariates, distance from patient residence to transplant center did not predict placement on the transplant waitlist. In contrast, race, neighborhood poverty, gender, age, diabetes, hypertension, body mass index, albumin, and the use of erythropoietin at dialysis initiation was associated with waitlisting. As neighborhood poverty increased, the likelihood of waitlisting decreased for blacks compared with whites in each poverty category; in the poorest neighborhoods, blacks were 57% less likely to be waitlisted than whites. This study suggests that improving the allocation of kidneys may require a focus on poor communities.
Health Disparities in Kidney Transplantation for African Americans
American journal of nephrology, 2017
The persistent challenges of bridging healthcare disparities for African Americans (AAs) in need of kidney transplantation continue to be unresolved at the national level. This healthcare disparity is multifactorial: stemming from limited kidney donors suitable for AAs; inconsistent care coordination and suboptimal risk factor control; social determinants, low socioeconomic status, reduced access to care; and mistrust of clinicians and the healthcare system. There are numerous opportunities to significantly lessen the disparities in kidney transplantation for AAs through the following measures: the adoption of new care and patient engagement models that include education, enhanced practice-level cultural sensitivity, and timely referral as well as increased research on the impact of the environment on genetic risk, and implementation of new transplantation-related policies. Key Messages: This systematic review describes pretransplant concerns related to access to kidney transplantat...
Education is associated with reduction in racial disparities in kidney transplant outcome
Clinical Transplantation, 2012
In this study, we hypothesized that higher level of education might be associated with reduced racial disparities in renal transplantation outcomes. We used data from the United States Renal Data System (September 1, 1990-September 1, 2007) (n = 79 223) and analyzed two outcomes, graft loss and recipient mortality, using Cox models. Compared with whites, African Americans had increased risk of graft failure (HR, 1.48; p < 0.001) and recipient mortality (HR, 1.06; p = 0.004). Compared with recipients who graduated from college, all other education groups had inferior graft survival. Specifically, compared with college-graduated individuals, African Americans who never finished high school had the highest risk of graft failure (HR, 1.45; p < 0.001), followed by high school graduates (HR, 1.27; p < 0.001) and those with some college education (HR, 1.18; p < 0.001). A similar trend was observed in whites. In African Americans (compared with whites), the highest risk of graft failure was associated with individuals who did not complete high school (HR, 1.96; p < 0.001) followed by high school graduates (HR, 1.47; p < 0.001), individuals with some college education (HR, 1.45; p < 0.001), and college graduates (HR, 1.39; p < 0.001). A similar trend was observed with recipient mortality. In sum, higher education was associated with reduced racial disparities in graft and recipient survival.
