Cutting back on low-value health care practices supports sustainable kidney care.

July 2023 marked the hottest month on record, underscoring the urgent need for action on climate change. The imperative to reduce carbon emissions extends to all sectors, including health care, with it being responsible for 5.5% of global emissions. In decarbonizing health care, although much attention has focused on greening health care infrastructure and procurement, less attention has focused on reducing emissions through demand-side management. An important key element of this is reducing low-value care, given that ≈20% of global health care expenditure is considered low value. "Value" in health care, however, is subjective and dependent on how health outcomes are regarded. This review, therefore, examines the 3 main value perspectives specific to health care. Clinical effectiveness defines low-value care as interventions that offer little to no benefit or have a risk of harm exceeding benefits. Cost-effectiveness compares health outcomes versus costs compared with an alternative treatment. In this case, low-value care is care greater than a societal willingness to pay for an additional unit of health (quality-adjusted life year). Last, community perspectives emphasize the value of shared decision-making and patient-centered care. These values sit within broader societal values of ethics and equity. Any reduction in low-value care should, therefore, also consider patient autonomy, societal value perspectives and opportunity costs, and equity. Deimplementing entrenched low-value care practices without unnecessarily compromising ethics and equity will require tailored strategies, education, and transparency.

Equity and diversity in the nephrology workforce in Australia and New Zealand.

BACKGROUND: Despite diversity initiatives, inequities persist in medicine with negative implications for the workforce and patients. Little is known about workplace inequity in nephrology. AIM: To describe perceptions and experiences of bias by health professionals in the Australian and New Zealand Society of Nephrology (ANZSN), focussing on gender and race. METHODS: A web-based survey of ANZSN members recorded degree of perceived inequity on a Likert scale, ranging from 1 (none) to 5 (complete). Groups were compared using Mann-Whitney U-test and logistic regression. Comments were synthesised using qualitative methods to explore themes of inequity and pathways to an inclusive future. RESULTS: Of the 620 members of the ANZSN, there were 134 (22%) respondents, of whom 57% were women and 67% were White. The majority (88%) perceived inequities in the workforce. Perceived drivers of inequity were gender (84/113; 75%), carer responsibilities (74/113; 65%) and race (64/113; 56%). Half (74/131) had personally experienced inequity, based on gender in 70% (52/74) and race in 39% (29/75) with perceived discrimination coming from doctors, patients, academics and health administrators. White males were least likely (odds ratio 0.39; 95% confidence interval 0.18-0.90) to experience inequity. Dominant themes from qualitative analysis indicated that the major impacts of inequity were limited opportunities for advancement and lack of formal assistance for those experiencing inequities. Proposed solutions to reduce inequity included normalising the discourse on inequity at an organisational level, with policy changes to ensure diverse representation on committees and in executive leadership positions. CONCLUSIONS: Inequity, particularly driven by gender and race, is common for nephrology health professionals in Australia and New Zealand and impacts career progression.

Survey study of trends in adult nephrology advanced training in Australia and New Zealand.

BACKGROUND: There has been considerable growth in nephrology advanced trainee numbers in Australia and New Zealand, with uncertain effects on clinical experience, competence and employment outcomes. AIMS: To review the perceived adequacy and temporal trends of advanced training in nephrology in Australia and New Zealand by evaluating training experiences, personal views on important aspects of training and nephrology, career paths and early employment outcomes. METHODS: An online survey was distributed to members of the Australian and New Zealand Society of Nephrology through email in December 2020. Responses were sought from current trainees and from nephrologists qualifying since 2014. Likert scale proportions were calculated and group comparisons made using the Chi-squared test. RESULTS: A total of 88 participants returned the survey yielding a response rate of 32%, with a representative sample of trainees and consultants from across Australia and New Zealand. Training was reported as adequate in most aspects of clinical nephrology, although 88% of respondents felt poorly prepared for entering private practice and 61% reported inadequate training in kidney histopathology. Exposure to clinical procedures was variable, with adequate training in percutaneous kidney biopsy, but mostly inadequate training in dialysis access insertion. Sixty-nine percent of nephrologists completed their advanced training entirely in large urban centres and 85% worked in an urban area after training. Only 23% of consultants were engaged in full-time clinical employment in their first-year post-training and 78% were undertaking at least one of dual specialty training or a higher degree by research. Demand for subspecialty fellowships was high. CONCLUSION: Trainees and nephrologists in Australia and New Zealand are currently satisfied with their training in most aspects of nephrology; however, some clinical experiences are perceived as inadequate and early career paths after advanced training are increasingly diverse.

Burden of kidney failure from atheroembolic disease and association with survival in people receiving dialysis in Australia and New Zealand: a multi-centre registry study.

BACKGROUND: Cardiovascular disease is a leading cause of mortality in kidney failure (KF). Patients with KF from atheroembolic disease are at higher risk of cardiovascular disease than other causes of KF. This study aimed to determine survival on dialysis for patients with KF from atheroembolic disease compared with other causes of KF. METHODS: All adults (≥ 18 years) with KF initiating dialysis as the first kidney replacement therapy between 1 January 1990 and 31 December 2017 according to the Australia and New Zealand Dialysis and Transplant registry were included. Patients were grouped into either: KF from atheroembolic disease and all other causes of KF. Survival outcomes were assessed by the Kaplan-Meier method and Cox regression analysis adjusted for patient-related characteristics. RESULTS: Among 65,266 people on dialysis during the study period, 334 (0.5%) patients had KF from atheroembolic disease. A decreasing annual incidence of KF from atheroembolic disease was observed from 2008 onwards. Individuals with KF from atheroembolic disease demonstrated worse survival on dialysis compared to those with other causes of KF (HR 1.80, 95% confidence interval [CI] 1.61-2.03). The respective one- and five-year survival rates were 77 and 23% for KF from atheroembolic disease and 88 and 47% for other causes of KF. After adjustment for patient characteristics, KF from atheroembolic disease was not associated with increased patient mortality (adjusted HR 0.93 95% CI 0.82-1.05). CONCLUSIONS: Survival outcomes on dialysis are worse for individuals with KF from atheroembolic disease compared to those with other causes of KF, probably due to patient demographics and higher comorbidity.

Socio-economic disparity, access to care and patient-relevant outcomes after kidney allograft failure.

Social disparity is a major impediment to optimal health outcomes after kidney transplantation. In this study, we aimed to define the association between socio-economic status (SES) disparities and patient-relevant outcomes after kidney allograft failure. Using data from the Australia and New Zealand Dialysis and Transplant registry, we included patients with failed first-kidney allografts in Australia between 2005 and 2017. The association between residential postcode-derived SES in quintiles (quintile 1-most disadvantaged areas, quintile 5-most advantaged areas) with uptake of home dialysis (peritoneal or home haemodialysis) within the first 12-months post-allograft failure, repeat transplantation and death on dialysis were examined using competing-risk analysis. Of 2175 patients who had experienced first allograft failure, 417(19%) and 505(23%) patients were of SES quintiles 1 and 5, respectively. Compared to patients of quintile 5, quintile 1 patients were less likely to receive repeat transplants (adjusted subdistributional hazard ratio [SHR] 0.70,95%CI 0.55-0.89) and were more likely to die on dialysis (1.37 [1.04-1.81]), but there was no association with the uptake of home dialysis (1.02 [0.77-1.35]). Low SES may have a negative effect on outcomes post-allograft failure and further research is required into how best to mitigate this. However, small-scale variation within SES cannot be accounted for in this study.

Qualitative research methods and its application in nephrology.

Chronic kidney disease is associated with an increased risk of mortality, comorbidities and life-threatening complications. Invasive treatments including dialysis or transplantation, complex pharmacological therapies, dietary restrictions and the ongoing need to attend follow-up appointments can place a substantial treatment burden on patients and carers and impair quality of life. This highlights the need for care that is responsive to the needs of patients and involves them in decision-making to achieve the most appropriate healthcare outcomes. Shared decision-making and collaborative approaches to care require a deep awareness of the lived experiences and goals of patients. Qualitative research methods can provide insights into patients' experiences, values and priorities and inform practice and policy by uncovering their preferences for care. Qualitative methods are increasingly being used in standalone projects or in mixed methods studies (complementing quantitative studies) to make valuable contributions to patient-centred research. Patient-centred care, collaborations between patient and care provider, and shared decision-making that integrates with the patient's goals are central to quality healthcare. The efficacy of qualitative research lies in its ability to elicit patients' perspectives, values, priorities and goals that underpin shared decision making and care. This article discusses examples of how qualitative research has informed practice and policy in nephrology, provides a summary of qualitative research methods and outlines a guide on how to appraise, interpret and apply qualitative data.

International Society of Nephrology Global Kidney Health Atlas: structures, organization, and services for the management of kidney failure in Oceania and South East Asia.

Oceania and South East Asia (OSEA) is a socioeconomically, culturally, and ethnically diverse region facing a rising epidemic of noncommunicable diseases, including chronic kidney disease (CKD). The second iteration of the International Society of Nephrology Global Kidney Health Atlas aimed to provide a comprehensive evaluation of kidney care in OSEA. Of the 30 countries/territories in OSEA, 15 participated in the survey, representing 98.5% of the region's population. The median prevalence of treated kidney failure in OSEA was 1352 per million population (interquartile range, 966-1673 per million population), higher than the global median of 787 per million population. Although the general availability, access, and quality of kidney replacement therapy (i.e., dialysis and transplantation) was high in OSEA, inequalities in accessibility and affordability of kidney replacement therapy across the region resulted in variability between countries. According to the survey results, in a third of the participating countries (mostly lower-income countries), less than half the patients with kidney failure were able to access dialysis, whereas it was readily available to all with minimal out-of-pocket costs in high-income countries; similar variability in access to transplantation was also recorded. Limitations in workforce and resources vary across the region and were disproportionately worse in lower-income countries. There was little advocacy for kidney disease, moderate use of registries, restricted CKD detection programs, and limited availability of routine CKD testing in some high-risk groups across the region. International collaborations, as seen in OSEA, are important initiatives to help close the gaps in CKD care provision across the region and should continue receiving support from the global nephrology community.

Perspectives on blood pressure by patients on haemo- and peritoneal dialysis.

AIM: The management of blood pressure in patients requiring dialysis remains challenging and controversial. This study aimed to describe the perspectives of patients treated with peritoneal or haemodialysis regarding blood pressure, to inform patient-centred management. METHODS: We conducted a secondary thematic analysis of qualitative data from multiple data sets derived from the Standardised Outcomes in Nephrology (SONG) initiative. We extracted and analysed the responses of adult patients (aged 18 years or over) on haemodialysis and peritoneal dialysis, and their caregivers. Qualitative data were extracted from 26 focus groups, two international Delphi surveys and two consensus workshops completed as part of the SONG-Haemodialysis and SONG-Peritoneal dialysis projects. RESULTS: Collectively, the studies involved 644 patients and caregivers from 86 countries. We identified four themes: helpless and incapacitated (including the subthemes of disabling and debilitating symptoms, limiting ability to work, fear of "crashes" - a sudden drop in blood pressure - forced to depend on others); dismissed and ignored (disregarded as a problem, lacking information, education and reassurance); escalating medication burden; and taking control for improved self-management (determining thresholds in fluid management, establishing a routine for proactive monitoring). CONCLUSION: Blood pressure symptoms are debilitating for patients on dialysis and exacerbated by a perceived lack of information about how to understand and manage these symptoms. More patient-centred management of blood pressure, particularly symptom-causing blood pressure, in patients on dialysis is likely to substantially improve patient satisfaction and outcomes.

Novel trial strategies to enhance the relevance, efficiency, effectiveness, and impact of nephrology research.

Randomized controlled trials (RCTs) are considered the gold standard for evaluating the effectiveness of interventions. However, criticisms of traditional designs are that they can be inefficient, inflexible, expensive, and conducted in a manner disconnected from real-life clinical practice. Novel strategies and approaches are being utilized to overcome these limitations, including comprehensive consumer engagement, core outcome sets, novel trial designs, streamlined data collection, cost-effectiveness and return on investment evaluations, knowledge dissemination plans, and impact evaluation. These strategies can be implemented at the design, conduct, implementation, and dissemination stages of the trial process. This review aims to provide an overview of these strategies and approaches to improve the relevance, efficiency, effectiveness, and impact of nephrology research.

Identifying Important Outcomes for Young People With CKD and Their Caregivers: A Nominal Group Technique Study.

RATIONALE & OBJECTIVE: Chronic kidney disease (CKD) has wide-ranging and long-term consequences for young people and their families. The omission of outcomes that are important to young people with CKD and their caregivers limits knowledge to guide shared decision making. We aimed to identify the outcomes that are important to young people with CKD and their caregivers. STUDY DESIGN: We used the nominal group technique whereby participants identified and ranked outcomes and explained their priorities. SETTINGS & PARTICIPANTS: Young people with CKD (stages 1-5, dialysis, or transplantation) and their caregivers were purposively sampled from 6 centers across Australia, the United States, and Canada. ANALYTICAL APPROACH: Importance scores were calculated (scale of 0-1), and qualitative data were analyzed thematically. RESULTS: 34 patients (aged 8-21 years) and 62 caregivers participated in 16 groups and identified 48 outcomes. The 5 highest ranked outcomes for patients were survival (importance score, 0.25), physical activity (0.24), fatigue (0.20), lifestyle restrictions (0.20), and growth (0.20); and for caregivers, kidney function (0.53), survival (0.28), infection (0.22), anemia (0.20), and growth (0.17). 12 themes were identified reflecting their immediate and current priorities (wanting to feel normal, strengthening resilience, minimizing intrusion into daily life, imminent threats to life, devastating family burdens, and seeking control over health) and considerations regarding future impacts (protecting health/development, remaining hopeful, concern for limited opportunities, prognostic uncertainty, dreading painful and invasive procedures, and managing expectations). LIMITATIONS: Only English-speaking participants were recruited. CONCLUSIONS: Kidney function, infection, survival, and growth were the highest priorities for patients with CKD and their caregivers. Young people with CKD also prioritized highly the outcomes that directly affected their lifestyle and sense of normality, while caregiver's highest priorities concerned the long-term health of their child, current health problems, and the financial and family burdens of caring for a child with CKD.

Identifying patient-important outcomes in polycystic kidney disease: An international nominal group technique study.

AIM: Patients with autosomal dominant polycystic kidney disease (ADPKD) are at increased risk of premature mortality, morbidities and complications, which severely impair quality of life. However, patient-centered outcomes are not consistently reported in trials in ADPKD, which can limit shared decision-making. We aimed to identify outcomes important to patients and caregivers and the reasons for their priorities. METHODS: Nominal group technique was adopted involving patients with ADPKD and caregivers who were purposively selected from eight centres across Australia, France and the Republic of Korea. Participants identified, ranked and discussed outcomes for trials in ADPKD. We calculated an importance score (0-1) for each outcome and conducted thematic analyses. RESULTS: Across 17 groups, 154 participants (121 patients, 33 caregivers) aged 19 to 78 (mean 54.5 years) identified 55 outcomes. The 10 highest ranked outcomes were: kidney function (importance score 0.36), end-stage kidney disease (0.32), survival (0.21), cyst size/growth (0.20), cyst pain/bleeding (0.18), blood pressure (0.17), ability to work (0.16), cerebral aneurysm/stroke (0.14), mobility/physical function (0.12), and fatigue (0.12). Three themes were identified: threatening semblance of normality, inability to control and making sense of diverse risks. CONCLUSION: For patients with ADPKD and their caregivers, kidney function, delayed progression to end-stage kidney disease and survival were the highest priorities, and were focused on achieving normality, and maintaining control over health and lifestyle. Implementing these patient-important outcomes may improve the meaning and relevance of trials to inform clinical care in ADPKD.
