Abstract
BACKGROUND Racial/ethnic minorities face known disparities in likelihood of kidney transplantation. These disparities may be exacerbated when coupled with ongoing substance use, a factor also reducing likelihood of transplantation. We examined whether race/ethnicity in combination with ongoing substance use predicted incidence of transplantation. METHODS Patients were enrolled between March 2010 and October 2012 at the time of transplant evaluation. Substance use data were retrieved from transplant evaluations. Following descriptive analyses, the primary multivariable analyses evaluated whether, relative to the referent group (White patients with no substance use), racial/ethnic minority patients using any substances at the time of evaluation were less likely to receive transplants by the end of study follow-up (August 2020). RESULTS Among 1152 patients, 69% were non-Hispanic White, 23% non-Hispanic Black, and 8% Other racial/ethnic minorities. White, Black, and Other patients differed in percentages of current tobacco smoking (15%, 26%, and 18%, respectively; P = 0.002) and illicit substance use (3%, 8%, and 9%; P < 0.001) but not heavy alcohol consumption (2%, 4%, and 1%; P = 0.346). Black and Other minority patients using substances were each less likely to receive transplants than the referent group (hazard ratios ≤0.45, P ≤ 0.021). Neither White patients using substances nor racial/ethnic minority nonusers differed from the referent group in transplant rates. Additional analyses indicated that these effects reflected differences in waitlisting rates; once waitlisted, study groups did not differ in transplant rates. CONCLUSIONS The combination of minority race/ethnicity and substance use may lead to unique disparities in likelihood of transplantation. To facilitate equity, strategies should be considered to remove any barriers to referral for and receipt of substance use care in racial/ethnic minorities.

A scoping review of inequities in access to organ transplant in the United States. Int J Equity Health 2022; 21:22. [PMID: 35151327 PMCID: PMC8841123 DOI: 10.1186/s12939-021-01616-x] [Citation(s) in RCA: 53] [Impact Index Per Article: 26.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2021] [Accepted: 12/24/2021] [Indexed: 02/06/2023] Open
Abstract
Background Organ transplant is the preferred treatment for end-stage organ disease, yet the majority of patients with end-stage organ disease are never placed on the transplant waiting list. Limited access to the transplant waiting list combined with the scarcity of the organ pool result in over 100,000 deaths annually in the United States. Patients face unique barriers to referral and acceptance for organ transplant based on social determinants of health, and patients from disenfranchised groups suffer from disproportionately lower rates of transplantation. Our objective was to review the literature describing disparities in access to organ transplantation based on social determinants of health to integrate the existing knowledge and guide future research. Methods We conducted a scoping review of the literature reporting disparities in access to heart, lung, liver, pancreas and kidney transplantation based on social determinants of health (race, income, education, geography, insurance status, health literacy and engagement). Included studies were categorized based on steps along the transplant care continuum: referral for transplant, transplant evaluation and selection, living donor identification/evaluation, and waitlist outcomes. Results Our search generated 16,643 studies, of which 227 were included in our final review. Of these, 34 focused on disparities in referral for transplantation among patients with chronic organ disease, 82 on transplant selection processes, 50 on living donors, and 61 on waitlist management. In total, 15 studies involved the thoracic organs (heart, lung), 209 involved the abdominal organs (kidney, liver, pancreas), and three involved multiple organs. Racial and ethnic minorities, women, and patients in lower socioeconomic status groups were less likely to be referred, evaluated, and added to the waiting list for organ transplant. The quality of the data describing these disparities across the transplant literature was variable and overwhelmingly focused on kidney transplant. Conclusions This review contextualizes the quality of the data, identifies seminal work by organ, and reports gaps in the literature where future research on disparities in organ transplantation should focus. Future work should investigate the association of social determinants of health with access to the organ transplant waiting list, with a focus on prospective analyses that assess interventions to improve health equity.

[PMID: 34686138 PMCID: PMC8532382 DOI: 10.1186/s12882-021-02552-2] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2021] [Accepted: 10/06/2021] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Patients with kidney failure treated with dialysis or kidney transplantation experience difficulties maintaining employment due to the condition itself and the treatment. We aimed to establish the rate of employment before and after initiation of dialysis and kidney transplantation and to identify predictors of employment during dialysis and posttransplant. METHODS This systematic review and meta-analysis were carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines for studies that included employment rate in adults receiving dialysis or a kidney transplant. The literature search included cross-sectional or cohort studies published in English between January 1966 and August 2020 in the PubMed, Embase, and Cochrane Library databases. Data on employment rate, study population, age, gender, educational level, dialysis duration, kidney donor, ethnicity, dialysis modality, waiting time for transplantation, diabetes, and depression were extracted. Quality assessment was performed using the Newcastle-Ottawa Scale. Meta-analysis for predictors for employment, with odds ratios and confidence intervals, and tests for heterogeneity, using chi-square and I2 statistics, were calculated. PROSPERO registration number: CRD42020188853. RESULTS Thirty-three studies included 162,059 participants receiving dialysis, and 31 studies included 137,742 participants who received kidney transplantation. Dialysis patients were on average 52.6 years old (range: 16-79; 60.3% male), and kidney transplant patients were 46.7 years old (range: 18-78; 59.8% male). The employment rate (weighted mean) for dialysis patients was 26.3% (range: 10.5-59.7%); the employment rate was 36.9% pretransplant (range: 25-86%) and 38.2% posttransplant (range: 14.2-85%). Predictors for employment during dialysis and posttransplant were male, gender, age, being without diabetes, peritoneal dialysis, and higher educational level, and predictors of posttransplant: pretransplant employment included transplantation with a living donor kidney, and being without depression. CONCLUSIONS Patients with kidney failure had a low employment rate during dialysis and pre- and posttransplant. Kidney failure patients should be supported through a combination of clinical and social measures to ensure that they remain working.

Can J Kidney Health Dis 2020; 7:2054358120930977. [PMID: 32782812 PMCID: PMC7383632 DOI: 10.1177/2054358120930977] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2020] [Accepted: 04/14/2020] [Indexed: 11/18/2022] Open
Abstract
Purpose: Low socioeconomic status, race, ethnicity, and rural/remote populations are all associated with disparities in access, care, and outcomes for chronic kidney disease (CKD). There have been different interventions supported by Canadian renal programs to address these disparities. This article reviews the evidence for impact of strategies to reduce inequities experienced by vulnerable populations living with or at risk of CKD and to collate and share interprovincial targeted interventions through the newly formed “Canadian Senior Renal Leaders Community of Practice” focused on translating evidence into clinical practice and policy. Source of Information: A literature search of Medline, CINAHL, PubMed, and Google Scholar from 2008 to 2018 identified 13 reports of processes and interventions that have been implemented in Australia, Canada, and the United States to reduce inequities in CKD care and can be categorized into 3 broad areas: (1) early screening and prevention, (2) disease management and dialysis, and (3) pretransplant. Web sites from each Canadian jurisdiction and from Canadians Seeking Solutions and Innovations to Overcome Chronic Kidney Disease (Can-SOLVE CKD) Network were used to assess the current state of Canadian initiatives. Methods: Reviews were completed to gather information on renal initiatives for vulnerable populations, including (1) identification of populations that experience disparities in access to care or in outcomes in the context of CKD prevention and treatment and (2) interventions that have been implemented to reduce disparities in access, care, and outcomes for vulnerable populations with CKD. A current state summary of Canadian initiatives related to vulnerable populations was conducted through a review of publicly available information, including a review of renal program Web sites and a review of current projects related to vulnerable populations that are part of Can-SOLVE CKD. Can-SOLVE CKD is a Canadian Institutes of Health Research Strategy for Patient-Oriented Research (CIHR-SPOR) funded research network to transform the care of people affected by kidney disease. Key Findings: Interventions to improve inequities in access to CKD screening, disease management, and care are successful when developed with community engagement, provided to the patient in their own environment, and tailored to specific populations. Many provincial renal programs have implemented initiatives to support vulnerable populations with or at risk of CKD. Current projects funded through CIHR SPOR focus on underserved populations and involve partnerships with Indigenous populations. Many renal programs in Canada had or were in the process of implementing interventions to support vulnerable populations with CKD; however, information about the initiatives were not readily available online despite a strong interest and opportunity to support interprovincial knowledge sharing. Despite this common interest, little information is systematically shared between Canadian jurisdictions to support interprovincial sharing to promote evidence-informed policy and program development. Efforts will be made through the newly formed Canadian Senior Renal Leaders Community of Practice to collaborate and share learnings to inform future program and policy development, implementation, and evaluation. Limitations: As this was not a systematic review, literature search only encompassed studies published in English between 2008 and 2018. It is possible that populations and interventions were overlooked during the search and through the screening process. Furthermore, the controversial definition of “vulnerable” and literature that only came from Canada, the United States, and Australia limits the generalizability of this review.

Abstract
BACKGROUND Prior work has demonstrated how neighborhood poverty and racial composition impact racial disparities in access to the deceased donor kidney transplant waitlist, both nationally and regionally. We examined the association between neighborhood characteristics and racial disparities in time to transplant waitlist in Chicago, a diverse city with continued neighborhood segregation. METHODS Using data from the United States Renal Data System (USRDS) and the US Census, we investigated time from dialysis initiation to kidney transplant waitlisting for African American and white patients in Chicago using cause-specific proportional hazards analyses, adjusting for individual sociodemographic and clinical characteristics, as well as neighborhood poverty and racial composition. RESULTS In Chicago, African Americans are significantly less likely than whites to appear on the renal transplant waitlist (HR 0.73, P < .05). Compared to whites in nonpoor neighborhoods, African Americans in poor neighborhoods are significantly less likely to appear on the transplant waitlist (HR 0.61, P < .05). Over 69% of African Americans with ESRD live in these neighborhoods. CONCLUSIONS Consistent with national data, African Americans in Chicago have a lower likelihood of waitlisting than whites. This disparity is explained in part by neighborhood poverty, which impacts the majority of African American ESRD patients in Chicago.

Abstract
It is widely thought that patients with end-stage renal disease who remain vocationally active and/or commercially insured following dialysis initiation have better clinical outcomes and higher quality of life than those who do not. However, scientifically robust data are lacking. Here, we examined whether vocational status (active, N = 1848; inactive, N = 10,001) and, separately, insurance status (commercial, N = 4858; Medicare/self-pay, N = 13,329; Medicaid, N = 3528) were associated with clinical outcomes and Kidney Disease Quality of Life (KDQOL) scores among a cohort of patients who initiated dialysis at a large US dialysis organization during 2015-2016. Outcomes were considered from the day after index (31 days after dialysis initiation for vocational status and 1 day after initiation for insurance status) until the earliest of death, discontinuation of dialysis, transplant, loss to follow-up, or end of study (30 September 2016). Comparisons were made using intention-to-treat principles and generalized linear models adjusted for imbalanced patient characteristics, including sociodemographic variables. Vocational inactivity (vs. vocational activity) was independently associated with higher rates of mortality and hospitalization, lower rates of transplant, and lower KDQoL scores in 4 of 5 domains. Similar trends were observed when comparing Medicare/self-pay or Medicaid insurance to commercial insurance. Vocational activity, and separately, commercial insurance, were independently associated with better clinical and quality of life outcomes compared to other insurance and vocational categories. These findings may inform patient and physician education, and guide advocacy efforts.

Employment 12 months after kidney transplantation: An in-depth bio-psycho-social analysis of the Swiss Transplant Cohort. PLoS One 2017; 12:e0175161.

Abstract
BACKGROUND Return to work with or after a chronic disease is a dynamic process influenced by a variety of interactions between personal, work, societal and medical resources or constraints. The aim of this study was to identify predictors for employment 12 months after transplantation in kidney patients, applying a bio-psycho-social model. METHODS All kidney patients followed in the Swiss Transplant Cohort between May 2008 and December 2012, aged 18 to 65 were assessed before, 6 and 12 months after transplantation. RESULTS Of the 689 included patients, 56.2% worked 12 months post- transplantation compared to 58.9% pre-transplantation. Age, education, self-perceived health (6 months post- transplantation), pre- transplantation employment and receiving an organ from a living donor are significant predictors of employment post- transplantation. Moreover, while self-perceived health increased post- transplantation, depression score decreased only among those employed 12 months post- transplantation. Pre- transplantation employment status was the main predictor for post- transplantation employment (OR = 18.6) and was associated with sex, age, education, depression and duration of dialysis. An organ from a living donor (42.1%) was more frequent in younger patients, with higher education, no diabetes and shorter waiting time to surgery. CONCLUSION Transplantation did not increase employment in end-stage kidney disease patients but helped maintaining employment. Pre-transplantation employment has been confirmed to be the most important predictor of post-transplantation employment. Furthermore, socio-demographic and individual factors predicted directly and indirectly the post-transplantation employment status. With living donor, an additional predictor linked to social factors and the medical procedure has been identified.

Are There Inequities in Treatment of End-Stage Renal Disease in Sweden? A Longitudinal Register-Based Study on Socioeconomic Status-Related Access to Kidney Transplantation. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2017; 14:ijerph14020119. [PMID: 28134798 PMCID: PMC5334673 DOI: 10.3390/ijerph14020119] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/08/2016] [Revised: 01/13/2017] [Accepted: 01/20/2017] [Indexed: 11/29/2022]
Abstract
Socioeconomic status-related factors have been associated with access to kidney transplantation, yet few studies have investigated both individual income and education as determinates of access to kidney transplantation. Therefore, this study aims to explore the effects of both individual income and education on access to kidney transplantation, controlling for both medical and non-medical factors. We linked the Swedish Renal Register to national registers for a sample of adult patients who started Renal Replacement Therapy (RRT) in Sweden between 1 January 1995, and 31 December 2013. Using uni- and multivariate logistic models, we studied the association between pre-RRT income and education and likelihood of receiving kidney transplantation. For non-pre-emptive transplantation patients, we also used multivariate Cox proportional hazards regression analysis to assess the association between treatment and socioeconomic factors. Among the 16,215 patients in the sample, 27% had received kidney transplantation by the end of 2013. After adjusting for covariates, the highest income group had more than three times the chance of accessing kidney transplantation compared with patients in the lowest income group (odds ratio (OR): 3.22; 95% confidence interval (CI): 2.73–3.80). Patients with college education had more than three times higher chance of access to kidney transplantation compared with patients with mandatory education (OR: 3.18; 95% CI: 2.77–3.66). Neither living in the county of the transplantation center nor gender was shown to have any effect on the likelihood of receiving kidney transplantation. For non-pre-emptive transplantation patients, the results from Cox models were similar with what we got from logistic models. Sensitive analyses showed that results were not sensitive to different conditions. Overall, socioeconomic status-related inequities exist in access to kidney transplantation in Sweden. Additional studies are needed to explore the possible mechanisms and strategies to mitigate these inequities.

Abstract
Significant disparities in CKD rates and outcomes exist between black and white Americans. Health disparities are defined as health differences that adversely affect disadvantaged populations, on the basis of one or more health outcomes. CKD is the complex result of genetic and environmental factors, reflecting the balance of nature and nurture. Social determinants of health have an important role as environmental components, especially for black populations, who are disproportionately disadvantaged. Understanding the social determinants of health and appreciating the underlying differences associated with meaningful clinical outcomes may help nephrologists treat all their patients with CKD in an optimal manner. Altering the social determinants of health, although difficult, may embody important policy and research efforts, with the ultimate goal of improving outcomes for patients with kidney diseases, and minimizing the disparities between groups.

Abstract
Background Public and scientific concerns about the social gradient of end-stage renal disease and access to renal replacement therapies are increasing. This study investigated the influence of social inequalities on the (i) access to renal transplant waiting list, (ii) access to renal transplantation and (iii) patients’ survival. Methods All incident adult patients with end-stage renal disease who lived in Bretagne, a French region, and started dialysis during the 2004–2009 period were geocoded in census-blocks. To each census-block was assigned a level of neighborhood deprivation and a degree of urbanization. Cox proportional hazards models were used to identify factors associated with each study outcome. Results Patients living in neighborhoods with low level of deprivation had more chance to be placed on the waiting list and less risk of death (HR = 1.40 95%CI: [1.1–1.7]; HR = 0.82 95%CI: [0.7–0.98]), but this association did not remain after adjustment for the patients’ clinical features. The likelihood of receiving renal transplantation after being waitlisted was not associated with neighborhood deprivation in univariate and multivariate analyses. Conclusions In a mixed rural and urban French region, patients living in deprived or advantaged neighborhoods had the same chance to be placed on the waiting list and to undergo renal transplantation. They also showed the same mortality risk, when their clinical features were taken into account.

Abstract
Background Determining eligibility for a kidney transplant is an important decision. Practice guidelines define contraindications to transplantation; however many are not evidence based. Canadian guidelines recommend that patients unlikely to survive the wait period not be evaluated. The purpose of this study was to evaluate what proportion of patients with a contraindication would survive the wait time. Methods Consecutive incident dialysis patients (January 2006 to December 2012) with a contraindication, defined using Canadian guidelines, were studied. Mortality rates were determined for each individual contraindication. Theoretical survival to the median wait time to transplantation was calculated. Results Of 746 incident patients, 435 (58 %) were deemed to have a contraindication at dialysis start. Nearly 80 % had a contraindication with a high mortality rate (dementia, multisystem disease, etc.). Patients with high mortality rates were less likely to survive the wait list than be transplanted. Patients with non-adherence, obesity, and potentially reversible disease had relatively low mortality rates, were more likely to survive, and possibly be transplanted at a time with the prospect of a better outcome. Conclusions This study gives some credence that many patients with a contraindication are not likely to benefit. A better framework of defining contraindications is needed to allow better decision-making.

Abstract
OBJECTIVES We sought to determine the association between changes in unemployment, healthcare spending and stomach cancer mortality. METHODS Multivariate regression analysis was used to assess how changes in unemployment and public-sector expenditure on healthcare (PSEH) varied with stomach cancer mortality in 25 member states of the European Union from 1981 to 2009. Country-specific differences in healthcare infrastructure and demographics were controlled for 1- to 5-year time-lag analyses and robustness checks were carried out. RESULTS A 1% increase in unemployment was associated with a significant increase in stomach cancer mortality in both men and women [men: coefficient (R)=0.1080, 95% confidence interval (CI)=0.0470-0.1690, P=0.0006; women: R=0.0488, 95% CI=0.0168-0.0809, P=0.0029]. A 1% increase in PSEH was associated with a significant decrease in stomach cancer mortality (men: R=-0.0009, 95% CI=-0.0013 to -0.005, P<0.0001; women: R=-0.0004, 95% CI=-0.0007 to -0.0001, P=0.0054). The associations remained when economic factors, urbanization, nutrition and alcohol intake were controlled for, but not when healthcare resources were controlled for. Time-lag analysis showed that the largest changes in mortality occurred 3-4 years after any changes in either unemployment or PSEH. CONCLUSION Increases in unemployment are associated with a significant increase in stomach cancer mortality. Stomach cancer mortality is also affected by public-sector healthcare spending. Initiatives that bolster employment and maintain public-sector healthcare expenditure may help to minimize increases in stomach cancer mortality during economic downturns.
