A codesigned integrated kidney and diabetes model of care improves patient activation among patients from culturally and linguistically diverse backgrounds.

BACKGROUND: Little is known about the relationship between patients' cultural and linguistic backgrounds and patient activation, especially in people with diabetes and chronic kidney disease (CKD). We examined the association between culturally and linguistically diverse (CALD) background and patient activation and evaluated the impact of a codesigned integrated kidney and diabetes model of care on patient activation by CALD status in people with diabetes and CKD. METHODS: This longitudinal study recruited adults with diabetes and CKD (Stage 3a or worse) who attended a new diabetes and kidney disease service at a tertiary hospital. All completed the patient activation measure at baseline and after 12 months and had demographic and clinical data collected. Patients from CALD backgrounds included individuals who spoke a language other than English at home, while those from non-CALD backgrounds spoke English only as their primary language. Paired t-tests compared baseline and 12-month patient activation scores by CALD status. RESULTS: Patients from CALD backgrounds had lower activation scores (52.1 ± 17.6) compared to those from non-CALD backgrounds (58.5 ± 14.6) at baseline. Within-group comparisons showed that patient activation scores for patients from CALD backgrounds significantly improved by 7 points from baseline to 12 months follow-up (52.1 ± 17.6-59.4 ± 14.7), and no significant change was observed for those from non-CALD backgrounds (58.5 ± 14.6-58.8 ± 13.6). CONCLUSIONS: Among patients with diabetes and CKD, those from CALD backgrounds report worse activation scores. Interventions that support people from CALD backgrounds with comorbid diabetes and CKD, such as the integrated kidney and diabetes model of care, may address racial and ethnic disparities that exist in patient activation and thus improve clinical outcomes. PATIENT OR PUBLIC CONTRIBUTION: Patients, caregivers and national consumer advocacy organisations (Diabetes Australia and Kidney Health Australia) codesigned a new model of care in partnership with healthcare professionals and researchers. The development of the model of care was informed by focus groups of patients and healthcare professionals and semi-structured interviews of caregivers and healthcare professionals. Patients and caregivers also provided a rigorous evaluation of the new model of care, highlighting its strengths and weaknesses.

Renal physiology and kidney injury during intense (CrossFit®) exercise.

BACKGROUND: High-intensity training (HIT) programmes are popularly associated with improvements in exercise efficiency and body composition, although, at extremes, have been accompanied by concerns of secondary rhabdomyolysis and severe acute kidney injury (AKI). Beyond the anecdotal, robust literature on the physiological impact of HIT on renal function is currently limited. AIMS: To investigate the acute impact of high-intensity (CrossFit®) training on renal function, and to evaluate the incidence of AKI by Risk, Injury, Failure, Loss, End-stage renal disease (RIFLE) criteria following CrossFit® training. METHODS: Clinical and biochemical parameters were measured in 22 healthy adults before and after two CrossFit® workouts: 'Fran' (12 men, 10 women) and 'Macho Man' (9 men, 4 women). RESULTS: Serum creatinine increased by 16 ± 10 µmol/L following Fran and 18 ± 12 µmol/L following Macho Man (P < 0.05). Cystatin C did not change significantly following Fran and increased by 0.06 ± 0.06 mg/L (P < 0.05) following Macho Man. AKI, as defined by RIFLE 'Risk' criteria, was observed in 5/22 (23%) participants following Fran and 5/13 (38%) participants following Macho Man. Urinary albumin/creatinine ratio rose by 18.7 ± 18.3 and 5.2 ± 6.0 mg/mmol following Fran and Macho Man respectively off non-albuminuric baselines (P < 0.05). CONCLUSIONS: Intense (CrossFit®) exercise is associated with significant metabolic demands and alterations in parameters of renal physiology and function. The observed rise in both conventional and novel biomarkers of renal function following the workout Macho Man specifically might indicate a degree of transient subclinical functional impairment with CrossFit®-type training.

The association of frailty with chronic kidney disease in older adults using the ASPirin in reducing events in the elderly cohort.

Frailty and chronic kidney disease (CKD) both increase with age and are prevalent in older adults. However, studies in older adults examining the relationship between frailty and milder impairments of kidney function are relatively sparse. We examined the cross-sectional association of baseline estimated glomerular filtration rate (eGFR), albuminuria and CKD ([eGFR <60 ml/min/1.73 m2 ] and/or albuminuria [>3.0 mg/mmol]) with prefrailty and frailty in the ASPirin in Reducing Events in the Elderly (ASPREE) trial cohort of healthy older participants. Univariate logistic regression models measured the unadjusted odds ratios (OR) and 95% confidence intervals (CI) for prevalent combined prefrailty and frailty (respectively defined as presence of 1-2 or 3+ of 5 modified fried criteria) for the association between CKD, eGFR, albuminuria and other potential risk factors. Multivariable models calculated OR for prefrailty-frailty adjusted for potential confounders and either CKD, (i) eGFR and albuminuria measured as either continuous variables; (ii) or categorical variables; (iii). Of 17 759 eligible participants, 6934 were classified as prefrail, 389 were frail. CKD, eGFR and albuminuria were all associated with combined prefrailty-frailty on univariate analysis. In the multivariable modelling, neither CKD (reduced eGFR and/or albuminuria), nor eGFR (either continuous or categorical variables) were associated with prefrailty-frailty. However, albuminuria, either as a continuous variable (OR [95% CI] 1.07 [1.04-1.10]; p < .001), or categorical variable (OR 1.21 [1.08-1.36]; p = .001) was consistently associated with prefrailty-frailty. The complex relationship between albuminuria (which may be a biomarker for vascular inflammation), ageing, progressive CKD and frailty requires further investigation.

A co-designed integrated kidney and diabetes model of care improves mortality, glycaemic control and self-care.

BACKGROUND: Current healthcare models are ill-equipped for managing people with diabetes and chronic kidney disease (CKD). We evaluated the impact of a new diabetes and kidney disease service (DKS) on hospitalization, mortality, clinical and patient-relevant outcomes. METHODS: Longitudinal analyses of adult patients with diabetes and CKD (Stages 3a-5) were performed using outpatient and hospitalization data from January 2015 to October 2018. Data were handled according to whether patients received the DKS intervention (n = 196) or standard care (n = 7511). The DKS provided patient-centred, coordinated multidisciplinary assessment and management of patients. Primary analyses examined hospitalization and mortality rates between the two groups. Secondary analyses evaluated the impact of the DKS on clinical target attainment, changes in estimated glomerular filtration rate (eGFR), glycated haemoglobin A1c (HbA1c), self-care and patient activation at 12 months. RESULTS: Patients who received the intervention had a higher hospitalization rate {incidence rate ratio [IRR] 1.20 [95% confidence interval (CI) 1.13-1.30]; P < 0.0001}, shorter median length of stay {2 days [interquartile range (IQR) 1-6] versus 4 days [IQR 1-9]; P < 0.0001} and lower all-cause mortality rate [IRR 0.4 (95% CI 0.29-0.64); P < 0.0001] than those who received standard care. Improvements in overall self-care [mean difference 2.26 (95% CI 0.83-3.69); P < 0.001] and in statin use and eye and feet examinations were observed. The mean eGFR did not change significantly after 12 months [mean difference 1.30 mL/min/1.73 m2 (95% CI -4.17-1.67); P = 0.40]. HbA1c levels significantly decreased by 0.40, 0.35, 0.34 and 0.23% at 3, 6, 9 and 12 months of follow-up, respectively. CONCLUSIONS: A co-designed, person-centred integrated model of care improved all-cause mortality, kidney function, glycaemic control and self-care for patients with diabetes and CKD.

Representativeness of the PDOPPS cohort compared to the Australian PD population.

BACKGROUND: The Peritoneal Dialysis Outcomes and Practice Patterns Study (PDOPPS) is an international, prospective study following persons treated by peritoneal dialysis (PD) to identify modifiable practices associated with improvements in PD technique and person survival. The aim of this study was to assess the representativeness of the Australian cohort included in PDOPPS compared to the complete Australian PD population, as reported to the Australia and New Zealand Dialysis and Transplant (ANZDATA) Registry. METHODS: Adults with at least one PD treatment reported to ANZDATA Registry during the census period of PDOPPS Phase I (November 2014 to April 2018) were compared to the Australian PDOPPS cohort. The primary outcomes were the representativeness of centres and persons. Secondary outcomes explored the association of person characteristics with consent to study participation. RESULTS: After data linkage, 511 PDOPPS participants were compared to 5616 Australians treated with PD. Within centres eligible for PDOPPS, selected centres were similar to other Australian centres. The PDOPPS participants' cohort tended to include older persons, more males, a higher proportion of Caucasians and more persons with higher socioeconomic advantage compared to the Australian PD population. Differences in distribution across sex and ethnicities between the PDOPPS cohort and the overall PD population were in part due to the selection and consent processes, during which females and non-Caucasians were more likely to not consent to PDOPPS participation. CONCLUSION: Sampling methods used in PDOPPS allowed for good national representativeness of the included centres. However, representativeness of the unweighted PDOPPS sample was suboptimal in regard to some participant characteristics.

Home before Hospital: a whole of system re-design project to improve rates of home-based dialysis therapy: Experience and outcomes over 8 years.

BACKGROUND: Despite evidence that clinical outcomes for patients treated with peritoneal dialysis (PD) or home haemodialysis are better than for patients treated with conventional satellite or hospital-based haemodialysis, rates of home-based dialysis therapies world-wide remain low. Home-based dialysis care is also cost-effective and indeed the favoured dialysis option for many patients. METHODS & OBJECTIVES: Using a lean-thinking framework and established change management methodology, a project embracing a system-wide approach at making a change where a 'Home before Hospital' philosophy underpinned all approaches to dialysis care was undertaken. Three multidisciplinary working groups (pathway, outreach and hybrid) were established for re-design and implementation. The primary aim was to improve home-based dialysis therapy prevalence rates from a baseline of 14.8% by ≥2.5%/year to meet a target of 35%, whilst not only maintaining but improving the quality of care provided to patients requiring maintenance dialysis. A 'future' state pathway was developed after review of the 'current' state (Pathway Working Group) and formed the basis on which a nurse-led outreach service (Outreach Working Group) was established. With the support of the multidisciplinary team, the outreach service model focussed on early, consistent, and frequent education, patient support in decision-making, and clinician engagement. RESULTS: A target prevalence of >30% for home-based therapies (mainly achieved with PD) was achieved within 2 years. This prevalence rate reached 35% within 3 years and was maintained at 8 years. In addition, selected patients already on maintenance satellite-based haemodialysis (Hybrid Working Group) were educated to achieve high levels of proficiencies in self-care. CONCLUSION: Having the system-wide approach to a Quality Improvement Process and using established principles and change management processes, the successful implementation of a new sustainable model of care focussed on home-based dialysis therapy was achieved. A key feature of the model (through outreach) was early nurse-led education and support of patients in decision-making and ongoing support through multidisciplinary care.

Subgroup analysis of the ASPirin in Reducing Events in the Elderly randomized clinical trial suggests aspirin did not improve outcomes in older adults with chronic kidney disease.

The role of aspirin for primary prevention in older adults with chronic kidney disease (CKD) is unclear. Therefore, post hoc analysis of the randomized controlled trial ASPirin in Reducing Events in the Elderly (ASPREE) was undertaken comparing 100 mg of enteric-coated aspirin daily against matching placebo. Participants were community dwelling adults aged 70 years and older in Australia, 65 years and older in the United States, all free of a history of dementia or cardiovascular disease and of any disease expected to lead to death within five years. CKD was defined as present at baseline if either eGFR under 60mL/min/1.73m2 or urine albumin to creatinine ratio 3 mg/mmol or more. In 4758 participants with and 13004 without CKD, the rates of a composite endpoint (dementia, persistent physical disability or death), major adverse cardiovascular events and clinically significant bleeding in the CKD participants were almost double those without CKD. Aspirin's effects as estimated by hazard ratios were generally similar between CKD and non-CKD groups for dementia, persistent physical disability or death, major adverse cardiovascular events and clinically significant bleeding. Thus, in our analysis aspirin did not improve outcomes in older people while increasing the risk of bleeding, with mostly consistent effects in participants with and without CKD.

Health-related quality of life among patients with comorbid diabetes and kidney disease attending a codesigned integrated model of care: a longitudinal study.

OBJECTIVE: To evaluate the impact of an integrated diabetes and kidney disease model of care on health-related quality of life (HRQOL) of patients with comorbid diabetes and chronic kidney disease (CKD). RESEARCH DESIGN AND METHODS: A longitudinal study of adult patients (over 18 years) with comorbid diabetes and CKD (stage 3a or worse) who attended a new diabetes kidney disease service was conducted at a tertiary hospital. A questionnaire consisting of demographics, clinical data, and the Kidney Disease Quality of Life (KDQOL-36) was administered at baseline and after 12 months. Paired t-tests were used to compare baseline and 12-month scores. A subgroup analysis examined the effects by patient gender. Multiple regression analysis examined the factors associated with changes in scores. RESULTS: 179 patients, 36% of whom were female, with baseline mean±SD age of 65.9±11.3 years, were studied. Across all subscales, HRQOL did not significantly change over time (p value for all mean differences >0.05). However, on subgroup analysis, symptom problem list and physical composite summary scores increased among women (MD=9.0, 95% CI 1.25 to 16.67; p=0.02 and MD=4.5, 95% CI 0.57 to 8.42; p=0.03 respectively) and physical composite scores decreased among men (MD=-3.35, 95% CI -6.26 to -0.44; p=0.03). CONCLUSION: The HRQOL of patients with comorbid diabetes and CKD attending a new codesigned, integrated diabetes and kidney disease model of care was maintained over 12 months. Given that HRQOL is known to deteriorate over time in this high-risk population, the impact of these findings on clinical outcomes warrants further investigation.

Cost-effectiveness of transplanting lungs and kidneys from donors with potential hepatitis C exposure or infection.

Organ transplant guidelines in many settings recommend that people with potential hepatitis C virus (HCV) exposure or infection are deemed ineligible to donate. The recent availability of highly-effective treatments for HCV means that this may no longer be necessary. We used a mathematical model to estimate the expected difference in healthcare costs, difference in disability-adjusted life years (DALYs) and cost-effectiveness of removing HCV restrictions for lung and kidney donations in Australia. Our model suggests that allowing organ donations from people who inject drugs, people with a history of incarceration and people who are HCV antibody-positive could lead to an estimated 10% increase in organ supply, population-level improvements in health (reduction in DALYs), and on average save AU$2,399 (95%CI AU$1,155-3,352) and AU$2,611 (95%CI AU$1,835-3,869) per person requiring a lung and kidney transplant respectively. These findings are likely to hold for international settings, since this policy change remained cost saving with positive health gains regardless of HCV prevalence, HCV treatment cost and waiting list survival probabilities. This study suggests that guidelines on organ donation should be revisited in light of recent changes to clinical outcomes for people with HCV.

The impact of an integrated diabetes and kidney service on patients, primary and specialist health professionals in Australia: A qualitative study.

BACKGROUND: To address guideline-practice gaps and improve management of patients with both diabetes and chronic kidney disease (CKD), we involved patients, health professionals and patient advocacy groups in the co-design and implementation of an integrated diabetes-kidney service. OBJECTIVE: In this study, we explored the experiences of patients and health-care providers, within this integrated diabetes and kidney service. METHODS: 5 focus groups and 2 semi-structured interviews were conducted amongst attending patients, referring primary health professionals, and attending specialist health professionals. Maximal variation sampling was used for both patients and referring primary health professionals to ensure an equal representation of males and females, and patients of different CKD stages. All discussions were audiotaped and transcribed verbatim, before being thematically analysed independently by 2 researchers. RESULTS: The mean age (SD) for specialist health professionals, primary care professionals and patients who participated was 45 (11), 44 (15) and 68 (5) years with men being 50%, 80% and 76% of the participants respectively. Key strengths of the diabetes and kidney service were noted to be better integration of care and a perception of improved health and management of health. Whilst some aspects of access such as time between referral and initial appointment and having fewer appointments improved, other aspects such as in-clinic waiting times and parking remained problematic. Specialist health professionals noted that health professional education could be improved. Patient self-management was also noted by to be an issue with some patients requesting more information and some health professionals expressing difficulty in empowering some patients. CONCLUSIONS: Health professionals and patients reported that a co-designed integrated diabetes kidney service improved integration of care and improved health and management of health. However, some aspects of the process of care, health professional education and patient self-management remained challenging.

Improving medication adherence in adult kidney transplantation (IMAKT): A pilot randomised controlled trial.

Resources to support long-term medication adherence in kidney transplantation are limited. This study aimed to determine the efficacy of an intervention designed for kidney transplant recipients to enhance medication adherence. A single-blind, multi-site, 12-month pilot randomised controlled trial was conducted at all five public hospitals providing adult kidney transplantation in Victoria, Australia. Participants were recruited at 4 to 6 weeks post-transplantation. Thirty-five participants were randomly assigned to a 3-month intervention, involving a face-to-face meeting (a medication review and a consumer-centred video) and health coaching every two weeks. Thirty-six were randomised to receive usual care. All participants were followed for nine months post-intervention. There were no differences in adherence between groups measured by Medication Event Monitoring System (MEMS), however, it was underutilised by 42% of participants. Based on the self-reported Basel Assessment of Adherence to Immunosuppressive Medications Scale (BAASIS©) score, the percentage of adherent participants decreased significantly between baseline and 3 to 12 months in the control group (p-values < 0.001) whilst the percentage of adherent participants in the intervention group remained constant over time. No group differences were detected in other outcomes. Due to the complex medication regimen, developing and testing a medication adherence intervention is difficult in kidney transplantation.

Patient-reported barriers and outcomes associated with poor glycaemic and blood pressure control in co-morbid diabetes and chronic kidney disease.

AIMS: In patients with comorbid diabetes and chronic kidney disease, the extent to which patient-reported barriers to health-care and patient reported outcomes influence the quality of health care is not well established. This study explored the association between patient-reported barriers to health-care, patient activation, quality of life and diabetes self-care, with attainment of glycaemic and blood pressure (BP) targets. METHODS: This cross-sectional study recruited adults with diabetes and CKD (eGFR 20 to <60 ml/min/1.73m2) across four hospitals. We combined clinical data with results from a questionnaire comprising measures of patient-identified barriers to care, the Patient Activation Measure (PAM), 12-Item Short Form Survey (SF-12), and the Summary of Diabetes Self-Care Activity (SDSCA). RESULTS: 199 patients, mean age 68.7 (SD 9.6), 70.4% male and 90.0% with type 2 diabetes were studied. Poor glycaemic control was associated with increased odds of patient reported "poor family support" (OR 4.90; 95% CI 1.80 to 13.32, p < 0.002). Poor BP control was associated with increased odds of patient reported, "not having a good primary care physician" (OR 6.01; 2.42 to 14.95, p < 0.001). The number of barriers was not associated with increased odds of poor control (all p > 0.05). CONCLUSIONS: Specific patient-reported barriers, lack of patient perceived family and primary care physician support, are associated with increased odds of poor glycaemic and blood pressure control respectively. Interventions addressing these barriers may improve treatment target attainment.

Patient reported barriers are associated with low physical and mental well-being in patients with co-morbid diabetes and chronic kidney disease.

BACKGROUND: Little is known about how patient reported barriers to health care impact the quality of life (HRQoL) of patients with comorbid disease. We investigated patient reported barriers to health care and low physical and mental well-being among people with diabetes and chronic kidney disease (CKD). METHODS: Adults with diabetes and CKD (estimated Glomerular Filtration Rate < 60 ml/min/1.73m2) were recruited and completed a questionnaire on barriers to health care, the 12-Item HRQoL Short Form Survey and clinical assessment. Low physical and mental health status were defined as mean scores < 50. Logistic regression models were used. RESULTS: Three hundred eight participants (mean age 66.9 ± 11 years) were studied. Patient reported 'impact of the disease on family and friends' (OR 2.07; 95% CI 1.14 to 3.78), 'feeling unwell' (OR 4.23; 95% CI 1.45 to 12.3) and 'having other life stressors that make self-care a low priority' (OR 2.59; 95% CI 1.20 to 5.61), were all associated with higher odds of low physical health status. Patient reported 'feeling unwell' (OR 2.92; 95% CI 1.07 to 8.01), 'low mood' (OR 2.82; 95% CI 1.64 to 4.87) and 'unavailability of home help' (OR 1.91; 95% CI 1.57 to 2.33) were all associated with higher odds of low mental health status. The greater the number of patient reported barriers the higher the odds of low mental health but not physical health status. CONCLUSIONS: Patient reported barriers to health care were associated with lower physical and mental well-being. Interventions addressing these barriers may improve HRQoL among people with comorbid diabetes and CKD.

Predictors of chronic kidney disease and utility of risk prediction scores in HIV-positive individuals.

OBJECTIVE: The current study aimed to validate existing risk prediction scores and identify predictors of chronic kidney disease (CKD) in the setting of HIV. DESIGN AND METHODS: A retrospective cohort study of HIV-positive individuals (n = 748) with baseline estimated glomerular filtration rate (eGFR) more than 60 ml/min was conducted at the Alfred Hospital, Melbourne, Australia. Multivariable regression analysis was performed to determine factors associated with development of CKD, defined as two consecutive measurements of eGFR less than 60 ml/min. The performance of CKD risk scores proposed by the Data Collection on Adverse Events of Anti-HIV Drugs (D:A:D) Study Group and Scherzer and colleagues were estimated by the area under the receiver operator curve (AUROC). RESULTS: CKD developed in 37 individuals (5.0%), at a median of 4.7 (interquartile range 2.2, 6.2) years. Older age [odds ratio (OR) 3.03, 95% confidence interval (CI): 1.20, 7.65, P = 0.02] and lower baseline eGFR (OR 10.39, 95% CI: 4.73, 22.83, P < 0.001) were associated with the development of CKD. Neither current, nor cumulative tenofovir disoproxil fumarate (TDF) use was associated with progression to CKD [current TDF hazard ratio (HR) 1.05, 95% CI: 0.54, 2.07, P = 0.88; cumulative TDF HR 1.03, 95% CI: 0.86, 1.24, P = 0.75]. The short D:A:D and Scherzer scores were well calibrated, with the short D:A:D score demonstrating superior discrimination (short D:A:D AUROC 0.85, Scherzer AUROC 0.78, P = 0.02). CONCLUSION: Older individuals and those with a lower baseline eGFR are at higher risk for CKD. Risk prediction tools may be useful in identifying those at greatest risk, who may benefit from aggressive management of risk factors.

De novo or early conversion to everolimus and long-term cancer outcomes in kidney transplant recipients: A trial-based linkage study.

Choice of immunosuppression may modify the risk of cancer after kidney transplantation, however, long-term data are lacking. Using the Australian and New Zealand Dialysis and Transplant Registry, we compared the 9-year risk of incident cancer, non-melanoma skin cancer (NMSC), and death attributed to cancer among participants from Australia and New Zealand in four randomized-controlled trials which compared de novo or early switch to an everolimus-containing regimen with calcineurin-inhibitor-based triple therapy. An adjusted Cox-model with random effects was used to determine such risks. Two hundred seventy-nine patients (192 everolimus, 87 control) were followed for a median of 9 years (IQR 6.7, 11.2). Compared with control, everolimus use was not associated with a reduction in the risk of incident cancer, NMSC, or cancer-related death (unadjusted HR [95% CI] 0.86 [0.49-1.48], 0.58 [0.30-1.12], and 1.18 [0.32-4.38], respectively). Subgroup analyses showed a 56% reduction for NMSC in patients randomized to everolimus + reduced-dose calcineurin-inhibitor versus control (unadjusted HR 0.44 [0.21-0.92]), which remained significant after adjusting for age, gender and smoking (adjusted HR 0.45 [0.21-0.96]). Although de novo or early switch to everolimus did not alter the 9-year risk of incident cancer or cancer-related death, everolimus with reduced-dose calcineurin-inhibitor strategy may reduce the long-term risk of NMSC.

Models of care for co-morbid diabetes and chronic kidney disease.

Diabetes and chronic kidney disease (CKD) are two of the most prevalent co-morbid chronic diseases in Australia. The increasing complexity of multi-morbidity, and current gaps in health-care delivery for people with co-morbid diabetes and CKD, emphasize the need for better models of care for this population. Previously, proposed published models of care for co-morbid diabetes and CKD have not been co-designed with stake-holders or formally evaluated. Particular components of health-care shown to be effective in this population are interventions that: are structured, intensive and multifaceted (treating diabetes and multiple cardiovascular risk factors); involve multiple medical disciplines; improve self-management by the patient; and upskill primary health-care. Here we present an integrated patient-centred model of health-care delivery incorporating these components and co-designed with key stake-holders including specialist health professionals, general practitioners and Diabetes and Kidney Health Australia. The development of the model of care was informed by focus groups of patients and health-professionals; and semi-structured interviews of care-givers and health professionals. Other distinctives of this model of care are routine screening for psychological morbidity; patient-support through a phone advice line; and focused primary health-care support in the management of diabetes and CKD. Additionally, the model of care integrates with the patient-centred health-care home currently being rolled out by the Australian Department of Health. This model of care will be evaluated after implementation across two tertiary health services and their primary care catchment areas.

Known unknowns: Examining the burden of neurocognitive impairment in the end-stage renal failure population.

The burden of neurocognitive impairment (NCI) in patients receiving maintenance dialysis represents a spectrum of deficits across multiple cognitive domains that are associated with hospitalization, reduced quality-of-life, mortality and forced decision-making around dialysis withdrawal. Point prevalence data suggest that dialysis patients manifest NCI at rates 3- to 5-fold higher than the general population, with executive function the most commonly affected cognitive domain. The unique physiology of the renal failure state and maintenance dialysis appears to drive an excess of vascular dementia subtype compared to the general population where classical Alzheimer's disease predominates. Despite the absence of evidence-based cost-effective therapies for NCI, detecting it in this population creates opportunity to proactively personalize care through education, supported decision making and targeted communication strategies to cover specific areas of deficit and help define goals of care. This review discusses NCI in the dialysis setting, including developments in the definition of neurocognitive impairment, dialysis-specific epidemiology across modalities, screening strategies and opportunities for dialysis providers in this space.
