Abstract

Abstract Background Indigenous Australians have an incidence of end stage kidney disease 8-10 times higher than non-Indigenous Australians. The majority of research studies concerning Indigenous Australians have been performed in rural or remote regions, whilst the majority of Indigenous Australians actually live in urban settings. We studied prevalence and factors associated with markers of kidney disease in an urban Indigenous Australian cohort, and compared results with those for the general Australian population. Methods 860 Indigenous adult participants of the Darwin Region Urban Indigenous Diabetes (DRUID) Study were assessed for albuminuria (urine albumin-creatinine ratio≥2.5 mg/mmol males, ≥3.5 mg/mmol females) and low eGFR (estimated glomular filtration rate < 60 mls/min/1.73 m2). Associations between risk factors and kidney disease markers were explored. Comparison was made with the AusDiab cohort (n = 8,936 aged 25-64 years), representative of the general Australian adult population. Results A high prevalence of albuminuria (14.8%) was found in DRUID, whilst prevalence of low eGFR was 2.4%. Older age, higher HbA1c, hypertension, higher C-reactive protein and current smoking were independently associated with albuminuria on multiple regression. Low eGFR was independently associated with older age, hypertension, albuminuria and higher triglycerides. Compared to AusDiab participants, DRUID participants had a 3-fold higher adjusted risk of albuminuria but not of low eGFR. Conclusions Given the significant excess of ESKD observed in Indigenous versus non-Indigenous Australians, these findings could suggest either: albuminuria may be a better prognostic marker of kidney disease than low eGFR; that eGFR equations may be inaccurate in the Indigenous population; a less marked differential between Indigenous and non-Indigenous Australians for ESKD rates in urban compared to remote regions; or that differences in the pathophysiology of chronic kidney disease exist between Indigenous and non-Indigenous populations.

Abstract

Aim: We aimed to describe the impact and experience of being deemed ineligible as a living kidney donor. Methods: Semi‐structured interviews were conducted with 27 ineligible donor candidates. Transcripts were analysed thematically. Results: Seven themes were identified: deriving health and relationship benefits in the process (strengthening emotional connection, identifying problematic health conditions); devastating loss and disappointment (harbouring guilt over personal failings, shattering confidence and hope, undermining relationships with extended family and friends, disrupting home dynamics); constrained within a rigid system (denied autonomy, resorting to other avenues); acknowledging as matter of fact (accepting the clinical decision, reassured by preventing a poor outcome); reluctant to relinquish the donor identity (unable to fulfil family duty, having the donor role stolen, holding onto other opportunities to donate); uncertainty in unpredictability, inconsistency and ambiguities (frustrated by inefficiencies, questioning clinician motivation, suspended donor status, unfairness in changeable eligibility criteria, unresolved concerns and questions of own health); and abandoned in despair (lacking practical support to meet eligibility criteria, ill prepared for rejection, dismissed and discarded by the system). Conclusion: Being deemed unsuitable for donation took an emotional toll on ineligible donor candidates who felt immense guilt for 'failing' the potential recipient. Ineligible donor candidates were frustrated and angry with the perceived lack of support from clinicians and rigidity of the evaluation process. Informing potential donors of available services, including psychological support, communicating the decision sensitively and with sufficient time, and full disclosure of their health status, may contribute to improved adjustment following the ineligibility decision. SUMMARY AT A GLANCE: Audit in the setting of renal transplant is not uncommon, but survey and evaluation of potential living donors who are turned down from donating kidneys are largely missing. This article fills the gap and found that informing the ineligible potential donors of available services, communicating the decision sensitively and with sufficient time, and full disclosure of their health status may all contribute to improved adjustment.

Abstract

BACKGROUND AND OBJECTIVES: Living kidney donor candidates accept a range of risks and benefits when they decide to proceed with nephrectomy. Informed consent around this decision assumes they receive reliable data about outcomes they regard as critical to their decision making. We identified the outcomes most important to living kidney donors and described the reasons for their choices. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Previous donors were purposively sampled from three transplant units in Australia (Sydney and Melbourne) and Canada (Vancouver). In focus groups using the nominal group technique, participants identified outcomes of donation, ranked them in order of importance, and discussed the reasons for their preferences. An importance score was calculated for each outcome. Qualitative data were analyzed thematically. RESULTS: Across 14 groups, 123 donors aged 27-78 years identified 35 outcomes. Across all participants, the ten highest ranked outcomes were kidney function (importance=0.40, scale 0-1), time to recovery (0.27), surgical complications (0.24), effect on family (0.22), donor-recipient relationship (0.21), life satisfaction (0.18), lifestyle restrictions (0.18), kidney failure (0.14), mortality (0.13), and acute pain/discomfort (0.12). Kidney function and kidney failure were more important to Canadian participants, compared with Australian donors. The themes identified included worthwhile sacrifice, insignificance of risks and harms, confidence and empowerment, unfulfilled expectations, and heightened susceptibility. CONCLUSIONS: Living kidney donors prioritized a range of outcomes, with the most important being kidney health and the surgical, lifestyle, functional, and psychosocial effects of donation. Donors also valued improvements to their family life and donor-recipient relationship. There were clear regional differences in the rankings.

Abstract

Research aims to improve health outcomes for patients. However, the setting of research priorities is usually performed by clinicians, academics, and funders, with little involvement of patients or caregivers and using processes that lack transparency. A national workshop was convened in Australia to generate and prioritize research questions in chronic kidney disease (CKD) among diverse stakeholder groups. Patients with CKD (n = 23), nephrologists/surgeons (n = 16), nurses (n = 8), caregivers (n = 7), and allied health professionals and researchers (n = 4) generated and voted on intervention questions across 4 treatment categories: CKD stages 1 to 5 (non-dialysis dependent), peritoneal dialysis, hemodialysis, and kidney transplantation. The 5 highest ranking questions (in descending order) were as follows: How effective are lifestyle programs for preventing deteriorating kidney function in early CKD? What strategies will improve family consent for deceased donor kidney donation, taking different cultural groups into account? What interventions can improve long-term post-transplant outcomes? What are effective interventions for post hemodialysis fatigue? How can we improve and individualize drug therapy to control post-transplant side effects? Priority questions were focused on prevention, lifestyle, quality of life, and long-term impact. These prioritized research questions can inform funding agencies, patient/consumer organizations, policy makers, and researchers in developing a CKD research agenda that is relevant to key stakeholders.

Abstract

We describe the prevalence of stage III and IV chronic kidney disease in Thailand from a representative sample of individuals aged 35 years and above using a stratified, multistage, cluster-sampling method. Population estimates were calculated by applying sampling weights from the 2000 Thai census. Glomerular filtration rates were estimated from serum creatinine using the Cockroft–Gault and the simplified Modification of Diet in Renal Disease (MDRD) formulae. The prevalence of stage III disease among individuals aged 35 years and above was estimated to be about 20% using the Cockroft–Gault formula and about 13% from the MDRD formula. Stage IV disease was present in about 0.9 and 0.6% of this population using the respective formulae. The highest prevalence rates were observed in less well-developed rural areas and the lowest in developed urban areas. The prevalence of chronic kidney disease was significantly higher than that reported in individuals over 40 years old from the United States for both stage III and IV disease and higher than the reported incidence in Taiwan and Australia. This high prevalence of chronic kidney disease in Thailand has obvious implications for the health of its citizens and for the allocation of health-care resources.

Abstract

Objectives: To describe the beliefs and attitudes to organ donation in the Arabic-speaking community. Design: Arabic-speaking participants were purposively recruited to participate in 6 focus groups. Transcripts were analysed thematically. Participants: 53 participants, aged 19–77 years, and originating from 8 countries, participated in 1 of 6 focus groups. Participants identified as Christian (73%), Islam (26%), Buddhist (2%) or did not identify with any religion (2%). Results: 6 themes (with subthemes) were identified; religious conviction; invisibility of organ donation; medical suspicion; owning the decision; and reciprocal benefit. Conclusions: Although organ donation is considered a generous life-saving ‘gift’, representative members of the Arabic-speaking community in Australia were unfamiliar with, unnerved by and sceptical about the donation process. Making positive decisions about organ donation would likely require resolving tensions between respecting family, community and religious values versus their individual autonomy. Providing targeted education about the process and benefits of organ donation within the Arabic community may clarify ambiguities surrounding cultural and religious-based views on organ donation, reduce taboos and suspicion towards donation, and in turn, lead to increased organ donation rates.
