Cost of dialysis therapies in rural and remote Australia - a micro-costing analysis. BMC Nephrol 2019; 20:231.

Abstract
BACKGROUND Maintenance dialysis is a costly and resource intense activity. In Australia, inadequate health infrastructure and poor access to technically skilled staff can limit service provision in remote areas where many Aboriginal dialysis patients live. With most studies based on urban service provision, there is little evidence to guide service development. However permanent relocation to an urban area for treatment can have significant social and financial impacts that are poorly quantified. This study is part of a broader project to quantify the costs and benefits of dialysis service models in urban and remote locations in Australia's Northern Territory (NT). METHODS We undertook a micro-costing analysis of dialysis service delivery costs in urban, rural and remote areas in the NT from the payer perspective. Recurrent maintenance costs (salaries, consumables, facility management and transportation) as well as capital costs were included. Missing and centralised costs were standardised; results were inflated to 2017 values and reported in Australian dollars. RESULTS There was little difference between the average annual cost for urban and rural services with respective median costs of $85,919 versus $84,629. However remote service costs were higher ($120,172 - $124,492), driven by higher staff costs. The inclusion of capital costs did not add substantially to annual costs. Annual home haemodialysis costs ($42,927) were similar to other jurisdictions despite the significant differences in program delivery and payment of expenses not traditionally borne by governments. Annual peritoneal dialysis costs ($58,489) were both higher than home and in-centre haemodialysis by recent national dialysis cost studies. CONCLUSION The cost drivers for staffed services were staffing models and patient attendance rates. Staff salaries and transport costs were significantly higher in remote models of care. Opportunities to reduce expenditure exist by encouraging community supported services and employing local staff. Despite the delivery challenges of home haemodialysis including high patient attrition, the program still provides a cost benefit compared to urban staffed services. The next component of this study will examine patient health service utilisation and costs by model of care to provide a more comprehensive analysis of the overall cost of providing services in each location.

Abstract
BACKGROUND The influence of health insurance systems on the treatment of end-stage kidney disease (ESKD) patients ispoorly understood. AIM We investigated how supplemental private health insurance (PHI) coverage impacted ESKD treatment modalitiesand patient outcomes. The influence of health insurance systems on the treatment of end-stage kidney disease (ESKD) patients is poorly understood. We investigated how supplemental private health insurance (PHI) coverage impacted ESKD treatment modalities and patient outcomes. METHODS All adult patients commencing ESKD treatment in New South Wales, Australia from 2000 to 2010 were identified using the Australia and New Zealand Dialysis and Transplant Registry. Data were linked to the state hospitalisation dataset to obtain insurance status, allowing the comparisons of mortality, ESKD treatment modality and health service utilisation between privately insured and public patients. RESULTS The cohort of 5737 patients included 38% (n = 2152) with PHI. At 1 year after ESKD treatment initiation, PHI patients had lower mortality (hazard ratio 0.84, 95% confidence interval (CI) 0.74-0.95, P = 0.01), were more likely to be receiving home haemodialysis (HD) (odds ratio (OR) 1.38, 95% CI 1.01-1.89, P = 0.04), to have been transplanted (OR 1.75, 95% CI 1.25-2.46, P = 0.001) and used fewer hospital days (incidence rate ratio 0.85, 95% CI 0.74-0.96, P = 0.01). After adjustment, PHI patients were more likely to initiate ESKD treatment with facility-based HD (OR 1.22, 95% CI 1.01-1.46, P = 0.03) but were less likely to be started on peritoneal dialysis (OR 0.81, 95% CI 0.67-0.98, P = 0.03). CONCLUSION Our findings suggest that supplemental PHI in Australia is associated with lower-risk ESKD treatment attributes and improved health outcomes. A greater understanding of the treatment pathways that deliver these outcomes may inform treatment for the broader ESKD treatment population.

Economic and quality of care evaluation of dialysis service models in remote Australia: protocol for a mixed methods study. BMC Health Serv Res 2017; 17:320. [PMID: 28468619 PMCID: PMC5415781 DOI: 10.1186/s12913-017-2273-5] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2016] [Accepted: 04/27/2017] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Australia's Northern Territory (NT) has the country's highest incidence and prevalence of kidney disease. Indigenous people from remote areas suffer the heaviest disease burden. Concerns regarding cost and sustainability limit the provision of dialysis treatments in remote areas and most Indigenous people requiring dialysis relocate to urban areas. However, this dislocation of people from their family, community and support networks may prove more costly when the broader health, societal and economic consequences for the individual, family and whole of government are considered. METHODS The Dialysis Models of Care Study is a large cross organisation mixed methods study. It includes a retrospective (2000-2014) longitudinal data linkage study of two NT cohorts: Renal Cohort 1- comprising approximately 2000 adults who received dialysis and Renal Cohort 2- comprising approximately 400 children of those adults. Linkage of administrative data sets from the Australian and New Zealand Dialysis and Transplant Registry, NT Departments of Health, Housing and Education by a specialist third party (SA/NT Datalink) will enable extraction of activity, financial and outcome data. Interviews with patients, clinicians and service providers, using a snowball technique, will canvass relevant issues and assist in determining the full costs and impacts of the five most used dialysis Models of Care. DISCUSSION The study uses a mixed methods approach to investigate the quantitative and qualitative dimensions of the full costs and outcomes associated with the choice of particular dialysis models of care for any given patient. The study includes a large data linkage component that for the first time links health, housing and education data to fully analyse and evaluate the impact on patients, their families and the broader community, resulting from the relocation of people for treatment. The study will generate a large amount of activity, financial and qualitative data that will investigate health costs less directly related to dialysis treatment, costs to government such as housing and/or education and the health, social and economic outcomes experienced by patients. This approach fills an evidence gap critical to health service planners.

Abstract
The impact of adverse maternal and early gestational issues, ranging from maternal-fetal interactions all the way through to premature birth, are recognized as having influence on the subsequent development of chronic diseases later in life. The development of chronic kidney disease (CKD) as a direct result of early life renal injury or a sequela of diseases such as hypertension or diabetes is a good model example of the potential impact that early life events may have on renal development and lifelong function. The global monetary and human resource cost of CKD is exorbitant. Socio-economic factors, along with other factors (genetic and environmental) may significantly influence the timing and display of phenotypic expression in fetuses and neonates at risk for developing CKD, yet very few of these factors are studied or well understood. In general our focus has been directed at treatment once CKD is established. This strategy has been and remains short-sighted and costly. Earlier understanding of the intrauterine determinants of renal mass development (i.e. environmental "biomes", poor maternal-fetal health, socio-economic factors impacting early life events, diet, access to value based health care and educational opportunities on disease evolution) may allow us an opportunity for earlier intervention. This article aims to provide some foundation for improved understanding of the maternal determinants of renal mass and function in the fetus and neonate.

Abstract
BACKGROUND Chronic kidney disease (CKD) is a common, serious and mostly asymptomatic condition that places considerable burden on the Australian healthcare system. Yet there is limited information on the patients with CKD who present to Australian primary care services, which represent the gateway to specialized care. METHODS Data pertaining to 31,897 patients who presented to a general practice in Western Australia, from 1 January 2013 to 30 June 2014 (inclusive), were extracted for review. Data included attendance records, comorbidities, diagnoses, and demographic details. Binary logistic regression was used to compare patients diagnosed with CKD by the consulting general practitioner with those without this diagnosis. RESULTS Of the 8629 patients who regularly attended the practice, 184 (2%) were diagnosed with CKD (mean age: 77.7 years; male: 57.1%). The stage of CKD was recorded in only 8.4% of cases. Patients with CKD averaged 11 more consultations in the past 18 months (mean difference 10.8, 95% CI [9.3, 12.3], p < .001). They were also more likely to: be male; be ex-smokers; be widowed; and to have a carer. Their most common comorbidities included acute infections, cerebrovascular or ischemic heart disease, osteopenia or osteoporosis, and cancer; 8.7% had died within the previous year. CONCLUSIONS Despite the prevalence of CKD, only one in five cases were recorded within this large practice. This reveals lost opportunities to monitor and manage patients with this chronic and common disease. Although this represents an important finding, this study is limited by the reliance on practice records, some of which were incomplete. Nevertheless, this study reveals two key findings. First, this disease is under-diagnosed and/or under-recorded. Second, patients with CKD have other, potentially unrelated, problems that may warrant attention.

Abstract
Kidney failure or ESRD affects approximately 650,000 Americans, whereas the number with earlier stages of CKD is much higher. Although CKD and ESRD are usually associated with adulthood, it is likely that the initial stages of CKD begin early in life. Many of these pathways are associated with low birth weight and disadvantaged socioeconomic status (SES) in childhood, translating childhood risk into later-life CKD and kidney failure. Social factors are thought to be fundamental causes of disease. Although the relationship between adult SES and CKD has been well established, the role of early childhood SES for CKD risk remains obscure. This review provides a rationale for examining the association between early-life SES and CKD. By collecting data on early-life SES and CKD, the interaction with other periods in the life course could also be studied, allowing for examination of whether SES trajectories (eg, poverty followed by affluence) or cumulative burden (eg, poverty at multiple time points) are more relevant to lifetime CKD risk.

Abstract
BACKGROUND Socio-economic status (SES) may be conceptualized as an individual's position in society, as determined by their income, occupation, education, wealth, and housing situation. This review summarizes the current literature regarding associations of these markers of SES with both chronic kidney disease (CKD) and associated poor outcomes. METHODS Literature searches were conducted in the US National Library of Medicine, National Institutes of Health, PubMed database using the search terms "chronic kidney disease" and "chronic renal insufficiency," combined with "socio-economic status," "income," "occupation," "employment," "education," "social class," "wealth," and "housing." Articles not in the English language, using non-human subjects, or primarily concerning subjects with ESRD or acute kidney injury were excluded. RESULTS Income is the most-studied aspect of SES in relation to CKD, but there is increasing literature involving occupation and education as well. Additionally, the associations of CKD and its outcomes with area-level and life course SES are both burgeoning areas of research. There are several research areas that remain mostly unexplored, including the roles of wealth and housing in defining SES-related risk in CKD. Additionally, none have explored the relative utility of composite versus individual indicators of SES in predicting risk of CKD and outcomes. CONCLUSION Given the overwhelming evidence that SES plays an important role in the development and progression of disease, the development and testing of more targeted interventions should be a top priority in CKD research. Continuing examination of these factors, with increased rigor and focus on potentially modifiable intermediate pathways, is needed.

Abstract
UNLABELLED Introduction. This study explores the geographical variation in renal replacement therapy (RRT) incidence and prevalence after adjusting for general population socio-demographics, renal unit treatment patterns and travel times. METHODS The UK Renal Registry provided data on all patients in England commencing RRT in 2007 and receiving RRT on 31 December 2007. Multilevel Poisson regression models were constructed separately for incidence and prevalence. Geographical Information Systems software enabled estimation of road travel times and renal unit catchment areas. Small area estimates of RRT prevalence were produced for all 354 local authority districts. RESULTS Adjusted RRT incidence rates were 1.4 (95% confidence interval 1.2-1.6) times higher in the most deprived areas and 1.7 (1.5-2.0) and 1.5 (1.3-1.7) times higher in areas with most Black and South Asian inhabitants (10+%), respectively. The proportion of a centre's patients on haemodialysis or transplanted were positively associated with RRT incidence (not prevalence); numbers of satellite units were negatively associated with RRT incidence (not prevalence). While only 3% of patients lived >30 min from a dialysis unit, there was an effect of travel time on RRT rates; individuals living 45+ min from a dialysis unit were 20% less likely to commence or receive RRT than those living within 15 min (Ptrend=0.36 and Ptrend<0.001, respectively). A 4-fold variation in adjusted local authority district RRT prevalence rates could not be explained. CONCLUSION Expansion of renal unit facilities in England has reduced travel times in most areas though the possibility of inequitable geographic access to RRT persists.

Abstract
AIM Indigenous people have a two- to tenfold increased risk of premature death from cardiovascular disease. We aimed to determine whether some key risk factors for cardiovascular disease occur more commonly in Aboriginal than non-Aboriginal Australian children. METHODS Children were enrolled from primary schools throughout New South Wales, the state with the highest number of Aboriginal people. Associations between ethnicity, gender, birthweight, socio-demographic status and hypertension, obesity, baseline and persistent albuminuria were determined. RESULTS A total of 2266 children (55% Aboriginal) were enrolled. Mean age was 8.9 years (+/-3.8 years). Obesity (body mass index >or=2 standard deviations) was detected in 7.1%, systolic hypertension (blood pressure >90th percentile) in 7.2%, diastolic hypertension in 5.9%, baseline albuminuria (albumin : creatinine >or=3.4 mg/mmol) in 7.3% and persistent albuminuria in 1.5% with no differences between Aboriginal and non-Aboriginal children. Hypertension was less common with increasing social disadvantage (trend P < 0.02). Increasing body mass index standard deviation was strongly associated with systolic and diastolic hypertension (both P < 0.0001). CONCLUSIONS Many risk factors for cardiovascular disease are already common in young children but not more prevalent in Aboriginal than in non-Aboriginal children. In all children, overweight and obesity have the strongest association with hypertension, but social disadvantage appears protective for hypertension. Our findings suggest that risk for cardiovascular health disparities seen in indigenous adults manifests beyond childhood and that a window of opportunity exists to prevent some of these outcomes.

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.
