A Discrete Choice Study of Patient Preferences for Dialysis Modalities

Consumer values, perspectives and experiences of psychological health when living with dialysis at home: An in-depth interview study

BACKGROUND

People treated with home dialysis report social and emotional isolation, fear of catastrophic events and concern about being a burden. There is a paucity of research exploring psychological well-being among consumers dialysing at home. We aimed to explore the psychological health issues related to home dialysis, and how these issues may impact on sustaining home-based treatment.

METHODS

We conducted a qualitative interview study with 36 consumers. We included patients with experience of home dialysis and caregivers. Thirteen participants had experienced peritoneal dialysis, seven home haemodialysis, seven had experienced both and nine caregivers. Data were analysed inductively to generate themes and a conceptual framework.

RESULTS

We identified four themes and subthemes: overwhelming isolation and disconnection (devastating isolation of home dialysis; abandoned from support; escalating anxiety; compounding impact of feeling like a burden); importance of support systems (impact on relationships; need for emotional support; reassurance through shared experiences; valuing trustworthy and committed clinicians); burden of distress (individualised feelings of low mood; grappling with stigma surrounding diagnosis; contemplating treatment withdrawal and suicide); seeking mental health support (normalising mental health support as a distinct entity in dialysis care; overcoming barriers to seeking mental health support; additional tools for mental health support and connection).

CONCLUSION

Consumers may experience intense psychological distress during home-based dialysis care. Increasing clinician and health services literacy about the management of psychological impacts of home-based dialysis may improve consumer safety, quality of life and sustainability of home treatment.

Evaluation and Measurement Properties of a Patient-Reported Experience Measure for Home Dialysis

BACKGROUND

No previously validated patient-reported experience measures exist for use among patients undergoing home dialysis. We tested the Home Dialysis Care Experience survey, a newly developed 26-item experience measure, among patients from 30 dialysis facilities in the United States.

METHODS

Using mail and telephone survey modalities, we approached 1372 patients treated with peritoneal dialysis or home hemodialysis for participation. Using the results from completed surveys, we evaluated item calibration by assessing item floor and ceiling effects. We tested three sets of composite scores and used factor analysis to assess model fit for each. We evaluated associations of composite scores with global ratings and separately with patient and dialysis facility characteristics. Finally, we measured test-retest reliability in patients who completed the survey at two separate time points.

RESULTS

Overall, 495 eligible patients completed at least one survey (response rate 36%). Of these, 49 completed the survey in Spanish and 61 completed a second survey within 30 days. We did not detect significant floor or ceiling effects, except for one item that demonstrated >90% responses at the top response option. Analyses supported one 12-item composite scale with high internal consistency reliability: Quality of Home Dialysis Care and Operations (Cronbach alpha=0.85). This scale strongly correlated with overall staff rating ( r =0.73) and overall center rating ( r =0.70). Patient demographic and dialysis facility characteristics were not consistently associated with composite scale scores or overall staff or center ratings. Intraclass correlation coefficients in the test-retest population were 0.74 for the Quality scale, 0.88 for overall staff rating, and 0.90 for overall center rating.

CONCLUSIONS

The Home Dialysis Care Experience survey is a 26-item measure that includes one composite scale and two global rating scores and is an informative tool to evaluate patient experience of care for home dialysis.

A systematic review of discrete choice experiments in stroke rehabilitation

OBJECTIVES

Existing research qualitatively explores consumer preferences for stroke rehabilitation interventions. However, it remains unclear which intervention characteristics are most important to consumers, and how these preferences may influence uptake and participation. Discrete choice experiments (DCE) provide a unique way to quantitatively measure preferences for health and health care. This study aims to explore how DCEs have been used in stroke rehabilitation and to identify reported consumer preferences for rehabilitation interventions.

MATERIAL AND METHODS

A systematic review of published stroke rehabilitation DCEs was completed (PROSPERO registration: CRD42021282578). Six databases (including CINAHL, MEDLINE, EconLIT) were searched from January 2000-March 2023. Data extracted included topic area, sample size, aim, attributes, design process, and preference outcomes. Descriptive and thematic analyses were conducted, and two methodological checklists applied to review quality.

RESULTS

Of 2,446 studies screened, five were eligible. Studies focused on exercise preference (n = 3), the structure and delivery of community services (n = 1), and self-management programs (n = 1). All had small sample sizes (range 50-146) and were of moderate quality (average score of 77%). Results indicated people have strong preferences for one-to-one therapy (over group-based), light-moderate intensity of exercise, and delivery by qualified therapists (over volunteers).

CONCLUSIONS

Few DCEs have been conducted in stroke rehabilitation, suggesting consumer preferences could be more rigorously explored. Included studies were narrow in the scope of attributes included, limiting their application to practice and policy. Further research is needed to assess the impact of differing service delivery models on uptake and participation.

Sociodemographic Disparities in Adults with Kidney Failure: A Meta-Analysis

This meta-analysis aims to assess current evidence regarding sociodemographic disparities among adults with kidney failure. Medline, Scopus, Web of Science, CENTRAL, and Google Scholar were systematically searched from inception to 20 February 2022. Overall, 165 cohort studies were included. Compared to White patients, dialysis survival was significantly better among Black (hazard ratio-HR: 0.68; 95% CI: 0.61-0.75), Asian (HR: 0.67; 95% CI: 0.61-0.72) and Hispanic patients (HR: 0.80; 95% CI: 0.73-0.88). Black individuals were associated with lower rates of successful arteriovenous fistula use, peritoneal dialysis and kidney transplantation, as well as with worse graft survival. Overall survival was significantly better in females after kidney transplantation compared to males (HR: 0.87; 95% CI: 0.84-0.90). Female sex was linked to higher rates of central venous catheter use and a lower probability of kidney transplantation. Indices of low SES were associated with higher mortality risk (HR: 1.22, 95% CI: 1.14-1.31), reduced rates of dialysis with an arteriovenous fistula, peritoneal dialysis and kidney transplantation, as well as higher graft failure risk. In conclusion, Black, Asian and Hispanic patients present better survival in dialysis, while Black, female and socially deprived patients demonstrate lower rates of successful arteriovenous fistula use and limited access to kidney transplantation. PROSPERO registration: CRD42022300839.

Factors Influencing the Choice of Automated Peritoneal Dialysis Treatment by Patients Receiving Home Peritoneal Dialysis

Objective

This study was conducted to understand the influencing factors for home peritoneal dialysis patients choosing APD and to provide a scientific basis for improving the completion rate of APD treatment and the follow-up of peritoneal dialysis patients.

Methods

The study was a cross-sectional questionnaire-based study. A total of 588 patients on peritoneal dialysis were randomly selected from 6 regions in Fujian Province in southern China using a stratified cluster sampling method.

Results

The mean age of the patients were 56.5 ± 14.73 years. In the univariate analysis, knowledge, user experience and family support were the factors that affected patients' choice of APD (all P < 0.05) and were positively correlated with the treatment utilization rate. In the multivariate analysis, 3 factors (treatment with APD, knowledge of APD, and family support) remained significantly associated not choosing APD. The selection rate for APD was 2.594 times higher among patients who had received APD than among patients who had never received APD. The selection rate for patients with "a lot of knowledge" about APD was 10.75 times that of patients with "no knowledge".

Conclusion

Patients' knowledge of APD, experience in application and family support were the main factors affecting the choice of APD as a treatment mode (P < 0.05) and were positively correlated with the treatment utilization rate. Further studies are needed to improve the APD treatment completion rates by modulation the above-mentioned factors.

Relevance to Clinical Practice

This study provides scientific evidence for improving APD treatment completion rates and improving patient quality of life.

Patient Preference Trade-offs for Next-Generation Kidney Replacement Therapies

BACKGROUND

Next-generation implantable and wearable KRTs may revolutionize the lives of patients undergoing dialysis by providing more frequent and/or prolonged therapy along with greater mobility compared with in-center hemodialysis. Medical device innovators would benefit from patient input to inform product design and development. Our objective was to determine key risk/benefit considerations for patients with kidney failure and test how these trade-offs could drive patient treatment choices.

METHODS

We developed a choice-based conjoint discrete choice instrument and surveyed 498 patients with kidney failure. The choice-based conjoint instrument consisted of nine attributes of risk and benefit pertinent across KRT modalities. Attributes were derived from literature reviews, patient/clinician interviews, and pilot testing. The risk attributes were serious infection, death within 5 years, permanent device failure, surgical requirements, and follow-up requirements. The benefit attributes were fewer diet restrictions, improved mobility, pill burden, and fatigue. We created a random, full-profile, balanced overlap design with 14 choice pairs plus five fixed tasks to test validity. We used a mixed-effects regression model with attribute levels as independent predictor variables and choice decisions as dependent variables.

RESULTS

All variables were significantly important to patient choice preferences, except follow-up requirements. For each 1% higher risk of death within 5 years, preference utility was lower by 2.22 ( β =-2.22; 95% confidence interval [CI], -2.52 to -1.91), while for each 1% higher risk of serious infection, utility was lower by 1.38 ( β =-1.46; 95% CI, -1.77 to -1.00) according to comparisons of the β coefficients. Patients were willing to trade a 1% infection risk and 0.5% risk of death to gain complete mobility and freedom from in-center hemodialysis ( β =1.46; 95% CI, 1.27 to 1.64).

CONCLUSIONS

Despite an aversion to even a 1% higher risk of death within 5 years, serious infection, and permanent device rejection, patients with kidney failure suggested that they would trade these risks for the benefit of complete mobility.

Partnering with patients and caregivers to enrich research and care in kidney disease: values and strategies

Patient and caregiver involvement broadens the scope of new knowledge generated from research and can enhance the relevance, quality and impact of research on clinical practice and health outcomes. Incorporating the perspectives of people with lived experience of chronic kidney disease (CKD) affords new insights into the design of interventions, study methodology, data analysis and implementation and has value for patients, healthcare professionals and researchers alike. However, patient involvement in CKD research has been limited and data on which to inform best practice is scarce. A number of frameworks have been developed for involving patients and caregivers in research in CKD and in health research more broadly. These frameworks provide an overall conceptual structure to guide the planning and implementation of research partnerships and describe values that are essential and strategies considered best practice when working with diverse stakeholder groups. This article aims to provide a summary of the strategies most widely used to support multistakeholder partnerships, the different ways patients and caregivers can be involved in research and the methods used to amalgamate diverse and at times conflicting points of view.

Choice of the Dialysis Modality: Practical Considerations

Chronic kidney disease and the need for kidney replacement therapy have increased dramatically in recent decades. Forecasts for the coming years predict an even greater increase, especially in low- and middle-income countries, due to the rise in metabolic and cardiovascular diseases and the aging population. Access to kidney replacement treatments may not be available to all patients, making it especially strategic to set up therapy programs that can ensure the best possible treatment for the greatest number of patients. The choice of the "ideal" kidney replacement therapy often conflicts with medical availability and the patient's tolerance. This paper discusses the pros and cons of various kidney replacement therapy options and their real-world applicability limits.

Prosthesis preferences for those with upper limb loss: Discrete choice study of PULLTY® for use in regulatory decisions

Introduction

The patient's voice in shared decision-making has progressed from physician's office to regulatory decision-making for medical devices with FDA's Patient Preference Initiative. A discrete-choice preference measure for upper limb prosthetic devices was developed to investigate patient's risk/benefit preference choices for regulatory decision making.

Methods

Rapid ethnographic procedures were used to design a discrete-choice measure describing risk and benefits of osseointegration with myoelectric control and test in a pilot preference study in adults with upper limb loss. Primary outcome is utility of each choice based conjoint (CBC) attribute using mixed-effects regression. Utilities with and without video, and between genders were compared.

Results

Strongest negative preference was for avoiding infection risk (B = -1.77, p < 0.001) and chance of daily pain (B = -1.22, p, 0.001). Strongest positive preference was for attaining complete independence when cooking dinner (B = 1.62, p < 0.001) and smooth grip patterns at all levels (B = 1.62, B = 1.28, B = 1.26, p < 0.001). Trade-offs showed a 1% increase in risk of serious/treatable infection resulted in a 1.77 decrease in relative preference. There were gender differences, and where video was used, preferences were stronger.

Conclusions

Strongest preferences were for attributes of functionality and independence versus connectedness and sensation but showed willingness to make risk-benefit trade-offs. Findings provide valuable information for regulatory benefit-risk decisions for prosthetic device innovations.

Patient experience in automated peritoneal dialysis with telemedicine monitoring during the COVID-19 pandemic in Mexico: Qualitative study

AIM

The aim of the study was to understand the experiences of patients on automated peritoneal dialysis (APD) during the period of confinement due to the COVID-19 pandemic.

DESIGN

Qualitative exploratory study, phenomenological through semi-structured telephone interview.

METHOD

A priori sampling was carried out with patients on APD with remote monitoring and telephone follow-up, in 13 hospitals in Mexico.

RESULTS

Twenty-nine informants, mean age 45.41 ± 16.93; 15 women and 14 men. The analysis revealed four categories of analysis: home isolation, clinical follow-up, socioeconomic challenges and infodemic. The experiences of these patients led them to somatize emotions, presenting symptoms such as anxiety, sadness, loneliness, sleep, eating and digestive disorders, situation that sets the tone for future research on telemedicine care models, coping styles, emotional support strategies and socioeconomic impact on patients with chronic home treatments during the pandemic.

Preferences for Risks and Benefits of Islet Cell Transplantation for Persons With Type 1 Diabetes With History of Episodes of Severe Hypoglycemia: A Discrete-Choice Experiment to Inform Regulatory Decisions

BACKGROUND

The advisory panel for US Food and Drug Administration (FDA) recently endorsed pancreatic islet cell transplantation (ICT) therapy for suboptimally controlled type 1 diabetes (T1D), and FDA approval is under consideration. An important part of regulatory approval includes the patient perspective, through discrete choice. We developed a discrete-choice instrument and used it to determine how 90 people with T1D weigh the risks and benefits of ICT to inform regulatory decisions.

METHODS

Sawtooth software created a random, full-profile, balanced-overlap experimental design for a measure with 8 attributes of ICT risks/benefits, each with 3 to 5 levels. We asked 18 random task pairs, sociodemographics, diabetes management, and hypoglycemia questions. Analysis was performed using random parameters logistic regression technique.

RESULTS

The strongest preference was for avoiding the highest chance (15%) of serious procedure-related complications (β = -2.03, P < 0.001). The strongest positive preference was for gaining 5-y insulin independence (β = 1.75, P < 0.001). The desire for 5-y HbA1C-defined clinical treatment success was also strong (β = 1.39, P < 0.001). Subgroup analysis suggested strong gender differences with women showing much higher preferences for all benefits (68% higher for 5-y insulin independence), and men were generally more risk averse than women. Those with high versus low diabetes distress showed 3 times stronger preference for 5-y insulin independence but also twice preference to avoid risks of serious complications.

CONCLUSION

Despite showing the most preference for avoiding serious ICT complications, people with T1D had a strong preference for achieving ICT benefits, especially insulin independence. We identified important attributes of ICT and demonstrated that patients are willing to make these trade-offs, showing support for the introduction of ICT.

Development of a Patient Preference Survey for Wearable Kidney Replacement Therapy Devices

Background

Recent innovations have the potential to disrupt the current paradigm for kidney failure treatment. The US Food and Drug Administration is committed to incorporating valid scientific evidence about how patients weigh the benefits and risks of new devices into their decision making, but to date, premarket submission of patient preference information (PPI) has been limited for kidney devices. With input from stakeholders, we developed a survey intended to yield valid PPI, capturing how patients trade off the potential benefits and risks of wearable dialysis devices and in-center hemodialysis.

Methods

We conducted concept elicitation interviews with individuals receiving dialysis to inform instrument content. After instrument drafting, we conducted two rounds of pretest interviews to evaluate survey face validity, comprehensibility, and perceived relevance. We pilot tested the survey with in-center hemodialysis patients to assess comprehensibility and usability further. Throughout, we used participant input to guide survey refinements.

Results

Thirty-six individuals receiving in-center or home dialysis participated in concept elicitation (N=20) and pretest (N=16) interviews. Participants identified reduced fatigue, lower treatment burden, and enhanced freedom as important benefits of a wearable device, and many expressed concerns about risks related to device disconnection-specifically bleeding and infection. We drafted a survey that included descriptions of the risks of serious bleeding and serious infection and an assessment of respondent willingness to wait for a safer device. Input from pretest interviewees led to various instrument modifications, including treatment descriptions, item wording, and risk-level explanations. Pilot testing of the updated survey among 24 in-center hemodialysis patients demonstrated acceptable survey comprehensibility and usability, although 50% of patients required some assistance.

Conclusions

The final survey is a 54-item web-based instrument that will yield estimates of the maximal acceptable risk for the described wearable device and willingness to wait for wearable devices with lower risk.

Understanding the low take-up of home-based dialysis through a shared decision-making lens: a qualitative study

OBJECTIVES

To explore how people with chronic kidney disease who are pre-dialysis, family members and healthcare professionals together navigate common shared decision-making processes and to assess how this impacts future treatment choice.

DESIGN

Coproductive qualitative study, underpinned by the Making Good Decisions in Collaboration shared decision-model. Semistructured interviews with a purposive sample from February 2019 - January 2020. Interview data were analysed using framework analysis. Coproduction of logic models/roadmaps and recommendations.

SETTING

Five Welsh kidney services.

PARTICIPANTS

95 participants (37 patients, 19 family members and 39 professionals); 44 people supported coproduction (18 patients, 8 family members and 18 professionals).

FINDINGS

Shared decision-making was too generic and clinically focused and had little impact on people getting onto home dialysis. Preferences of where, when and how to implement shared decision-making varied widely. Apathy experienced by patients, caused by lack of symptoms, denial, social circumstances and health systems issues made future treatment discussions difficult. Families had unmet and unrecognised needs, which significantly influenced patient decisions. Protocols containing treatment hierarchies and standards were understood by professionals but not translated for patients and families. Variation in dialysis treatment was discussed to match individual lifestyles. Patients and professionals were, however, defaulting to the perceived simplest option. It was easy for patients to opt for hospital-based treatments by listing important but easily modifiable factors.

CONCLUSIONS

Shared decision-making processes need to be individually tailored with more attention on patients who could choose a home therapy but select a different option. There are critical points in the decision-making process where changes could benefit patients. Patients need to be better educated and their preconceived ideas and misconceptions gently challenged. Healthcare professionals need to update their knowledge in order to provide the best advice and guidance. There needs to be more awareness of the costs and benefits of the various treatment options when making decisions.

The CKD bowel health study: understanding the bowel health and gastrointestinal symptom management in patients with chronic kidney disease: a mixed-methods observational longitudinal study (protocol)

BACKGROUND

Gastro-intestinal (GI) intolerance is a frequently reported outcome in patients with kidney failure receiving maintenance dialysis and those who have received kidney transplants. Symptoms of GI intolerance (diarrhoea, constipation, bloating, abdominal pain, heart burn, and reflux) are associated with significant reduction in quality of life, morbidity, and increased used of healthcare resources. Having chronic kidney disease (CKD), together with related changes in diet and medication, may alter the gut microbiota and the microbial-derived uraemic metabolites that accumulate in kidney failure, and contribute to various complications including chronic diarrhoea, opportunistic infections, and drug-related colitis. Despite the high disease burden among patients with kidney replacement therapies, GI symptoms are often under-recognised and, consequently limited resources and strategies are devoted to the management of gastrointestinal complications in patients with CKD.

METHODS

The CKD Bowel Health Study is a multi-centre mixed-methods observational longitudinal study to better understand the bowel health and GI symptom management in patients with CKD. The program comprises of a longitudinal study that will assess the burden and risk factors of GI intolerance in patients treated with maintenance dialysis; a semi-structured interview study that will describe experiences of GI intolerance (including symptoms, treatment, self-management) in transplant candidates and recipients; and a discrete choice experience to elicit patient preferences regarding their experiences and perspectives of various intervention strategies for the management of GI symptoms after kidney transplantation.

DISCUSSION

This proposed program of work aims to define the burden the GI intolerance in patients with kidney failure and generate evidence on the patients' experiences of GI intolerance and their perspectives on their clinical and own management strategies of these symptoms, ensuring a patient-centred approach to guide clinical decision making and to inform the best study design for intervention trials.

Exploring stakeholders and their requirements in the process of home hemodialysis: A literature review

Providing home hemodialysis (HHD) therapy is a complex process that not only requires the use of a complex technology but also involves a diverse group of stakeholders, and each stakeholder has their requirements and may not share a common interest. Bringing them together will require the alignment of their interests. A process management perspective can help to accomplish the alignment of their interests. To align their interests, it is crucial to identify interest groups and understand their interests. The main objective of this paper is to identify the stakeholders and represents their interests as a list of requirements in the HHD process. An extensive literature review has been carried out and PubMed was used for literature extraction. In total, 1848 articles were retrieved of which 80 have fulfilled the inclusion criteria. A large array of actors is identified and their interests/requirements at different stages of the HHD process are represented in the form of a list. They have both common and conflicting requirements in the HHD process. If these requirements are aligned and balanced, a stakeholder's driven treatment process will be developed and a real improvement will be achieved in the treatment process.

Advanced hemodialysis equipment for more eco-friendly dialysis

Healthcare in general and dialysis care in particular are contributing to resource consumption and, thus, have a notable environmental footprint. Dialysis is a life-saving therapy but it entails the use of a broad range of consumables generating waste, and consumption of water and energy for the dialysis process. Various stakeholders in the healthcare sector are called upon to develop and to take measures to save resources and to make healthcare and dialysis more sustainable. Among these stakeholders are manufacturers of dialysis equipment and water purification systems. Dialysis equipment and consumables, together with care processes need to be advanced to reduce waste generation, enhance recyclability, optimize water purification efficiency and water use. Joint efforts should thus pave the way to enable delivering green dialysis and to contribute to environmentally sustainable health care.

Is home hemodialysis a practical option for older people?

An increasing demand for in-center dialysis services has been largely driven by a rapid growth of the older population progressing to end-stage kidney disease. Since the onset of the COVID-19 pandemic, efforts to encourage home-based dialysis options have increased due to risks of infective transmission for patients receiving hemodialysis in center-based units. There are various practical and clinical advantages for patients receiving hemodialysis at home. However, the lack of caregiver support, cognitive and physical impairment, challenges of vascular access, and preparation and training for home hemodialysis (HHD) initiation may present as barriers to successful implementation of HHD in the older dialysis population. Assessment of an older patient's frailty status may help clinicians guide patients when making decisions about HHD. The development of an assisted HHD care delivery model and advancement of telehealth and technology in provision of HHD care may increase accessibility of HHD services for older patients. This review examines these factors and explores current unmet needs and barriers to increasing access, inclusion, and opportunities of HHD for the older dialysis population.

Anemia management for home dialysis including the new US public policy initiative

Patients with end-stage kidney disease (ESKD) requiring kidney replacement therapy are often treated in conventional dialysis centers at substantial cost and patient inconvenience. The recent United States Executive Order on Advancing American Kidney Health, in addition to focusing on ESKD prevention and reforming the kidney transplantation system, focuses on providing financial incentives to promote a shift toward home dialysis. In accordance with this order, a goal was set to have 80% of incident dialysis patients receiving home dialysis or a kidney transplant by 2025. Compared with conventional in-center therapy, home dialysis modalities, including both home hemodialysis and peritoneal dialysis, appear to offer equivalent or improved mortality, clinical outcomes, hospitalization rates, and quality of life in patients with ESKD in addition to greater convenience, flexibility, and cost-effectiveness. Treatment of anemia, a common complication of chronic kidney disease, may be easier to manage at home with a new class of agents, hypoxia-inducible factor-prolyl hydroxylase inhibitors, which are orally administered in contrast to the current standard of care of i.v. iron and/or erythropoiesis-stimulating agents. This review evaluates the clinical, quality-of-life, economic, and social aspects of dialysis modalities in patients with ESKD, including during the coronavirus disease 2019 pandemic; explores new therapeutics for the management of anemia in chronic kidney disease; and highlights how the proposed changes in Advancing American Kidney Health provide an opportunity to improve kidney health in the United States.

Economic Impact of Home Hemodialysis

Home hemodialysis (HD) is growing in the United States, but the economics of the modality are largely unknown, especially considering the unique aspects of home HD in the United States . In this review, I focus on details of Medicare coverage, which directly applies to most patients on dialysis and influences the policies of private insurers. Key details in Medicare comprise the relationship between home dialysis training and initial Medicare eligibility, reimbursement for home HD training, coverage of additional HD treatments (ie., in excess of 3 treatments per week), and monthly capitated payments to nephrologists. The overarching narrative is that frequent home HD directly increases Medicare costs for outpatient dialysis, but these added costs can be mitigated by lower inpatient expenditures if increased HD treatment frequency lowers the risk of cardiovascular hospitalization and infection control is emphasized. I also review recent international literature; conventional home HD exhibits a superior cost profile, whereas frequent home HD is generally cost-effective over multiple treatment years (ie, if early technique failure is avoided). Out-of-pocket expenses for patients should be considered. The future economics of home HD in the United States will be determined by new equipment, new adaptations of the modality, and new payment models.

Comparing Mortality of Peritoneal and Hemodialysis Patients in an Era of Medicare Payment Reform

BACKGROUND

Prior studies have shown peritoneal dialysis (PD) patients to have lower or equivalent mortality to patients who receive in-center hemodialysis (HD). Medicare's 2011 bundled dialysis prospective payment system encouraged expansion of home-based PD with unclear impacts on patient outcomes. This paper revisits the comparative risk of mortality between HD and PD among patients with incident end-stage kidney disease initiating dialysis in 2006-2013.

RESEARCH DESIGN

We conducted a retrospective cohort study comparing 2-year all-cause mortality among patients with incident end-stage kidney disease initiating dialysis via HD and PD in 2006-2013, using data from the US Renal Data System and Medicare. Analysis was conducted using Cox proportional hazards models fit with inverse probability of treatment weighting that adjusted for measured patient demographic and clinical characteristics and dialysis market characteristics.

RESULTS

Of the 449,652 patients starting dialysis between 2006 and 2013, the rate of PD use in the first 90 days increased from 9.3% of incident patients in 2006 to 14.2% in 2013. Crude 2-year mortality was 27.6% for patients dialyzing via HD and 16.7% for patients on PD. In adjusted models, there was no evidence of mortality differences between PD and HD before and after bundled payment (hazard ratio, 0.96; 95% confidence interval, 0.89-1.04; P=0.33).

CONCLUSIONS

Overall mortality for HD and PD use was similar and mortality differences between modalities did not change before versus after the 2011 Medicare dialysis bundled payment, suggesting that increased use of home-based PD did not adversely impact patient outcomes.

Physical performance and health-related quality of life among older adults on peritoneal dialysis: a cross-sectional study

PURPOSE

Identifying performance-based tests that meaningful for patients may facilitate the implementation of rehabilitation programs. The primary aim of this study was to determine the independent associations between different performance-based tests and health-related quality of life (HRQoL) among elderly peritoneal dialysis (PD) patients.

METHODS

This cross-sectional study was conducted in China. Patients on PD who were 60 years of age or above were included. HRQoL was assessed using the Medical Outcomes Study Short Form 36. Physical function was determined by handgrip strength, timed up and go (TUG) test, 5-repetition sit-to-stand test, and comfortable gait speed. Depressive symptoms were measured using the self-reported Geriatric Depression Scale (GDS-15). Multiple linear regression analyses were performed to examine the factors influencing HRQoL.

RESULTS

In total, 115 participants with a mean age of 69.7 were included (46 women and 69 men). TUG (β =- 0.460, p < 0.001), prealbumin (β = 0.223, p = 0.014), and education level (β = 0.183, p = 0.042) were associated with physical health. GDS score (β = - 0.475, p < 0.001), serum albumin level (β = 0.264, p = 0.003), and sex (β = 0.217, p = 0.012), were associated with mental HRQoL.

CONCLUSION

TUG could be a valuable test for use in clinical practice and research aiming at facilitating tailed exercise programs, as it was associated with self-perceived physical HRQoL and could be meaningful to elderly PD patients. Depressive symptoms and nutrition were another two important rehabilitation areas for optimizing the overall HRQoL of older adults on PD.

Health Policy for Dialysis Care in Canada and the United States

Contemporary dialysis treatment for chronic kidney failure is complex, is associated with poor clinical outcomes, and leads to high health costs, all of which pose substantial policy challenges. Despite similar policy goals and universal access for their kidney failure programs, the United States and Canada have taken very different approaches to dealing with these challenges. While US dialysis care is primarily government funded and delivered predominantly by private for-profit providers, Canadian dialysis care is also government funded but delivered almost exclusively in public facilities. Differences also exist for regulatory mechanisms and the policy incentives that may influence the behavior of providers and facilities. These differences in health policy are associated with significant variation in clinical outcomes: mortality among patients on dialysis is consistently lower in Canada than in the United States, although the gap has narrowed in recent years. The observed heterogeneity in policy and outcomes offers important potential opportunities for each health system to learn from the other. This article compares and contrasts transnational dialysis-related health policies, focusing on key levers including payment, finance, regulation, and organization. We also describe how policy levers can incentivize favorable practice patterns to support high-quality/high-value, person-centered care and to catalyze the emergence of transformative technologies for alternative kidney replacement strategies.

Effect of patient- and center-level characteristics on uptake of home dialysis in Australia and New Zealand: a multicenter registry analysis

BACKGROUND

Home-based dialysis therapies, home hemodialysis (HHD) and peritoneal dialysis (PD) are underutilized in many countries and significant variation in the uptake of home dialysis exists across dialysis centers. This study aimed to evaluate the patient- and center-level characteristics associated with uptake of home dialysis.

METHODS

The Australia and New Zealand Dialysis and Transplant (ANZDATA) Registry was used to include incident dialysis patients in Australia and New Zealand from 1997 to 2017. Uptake of home dialysis was defined as any HHD or PD treatment reported to ANZDATA within 6 months of dialysis initiation. Characteristics associated with home dialysis uptake were evaluated using mixed effects logistic regression models with patient- and center-level covariates, era as a fixed effect and dialysis center as a random effect.

RESULTS

Overall, 54 773 patients were included. Uptake of home-based dialysis was reported in 24 399 (45%) patients but varied between 0 and 87% across the 76 centers. Patient-level factors associated with lower uptake included male sex, ethnicity (particularly indigenous peoples), older age, presence of comorbidities, late referral to a nephrology service, remote residence and obesity. Center-level predictors of lower uptake included small center size, smaller proportion of patients with permanent access at dialysis initiation and lower weekly facility hemodialysis hours. The variation in odds of home dialysis uptake across centers increased by 3% after adjusting for the era and patient-level characteristics but decreased by 24% after adjusting for center-level characteristics.

CONCLUSION

Center-specific factors are associated with the variation in uptake of home dialysis across centers in Australia and New Zealand.

Patients’ and caregivers’ expectations and experiences of remote monitoring for peritoneal dialysis: A qualitative interview study

Background:

Peritoneal dialysis (PD) can offer more flexibility and independence compared with hemodialysis, yet uptake of PD remains low. Barriers to PD include the fear of dialyzing without medical assistance and uncertainty about recognizing and managing complications. There is increasing use of remote monitoring in automated peritoneal dialysis (APD), but little is known about its acceptability by patients and caregivers. We aimed to describe patients’ and caregivers’ expectations and experiences of remote monitoring for APD.

Methods:

Qualitative study design, using semi-structured face-to-face interviews of patients who either receiving PD or were considered eligible for PD, and their caregivers. Transcripts were analyzed using thematic analysis.

Results:

Of the 34 participants, 27 were patients and the remainder caregivers. Four themes (with subthemes) were identified reducing patient burden (seeking reassurance and shared responsibility, convenience and accuracy); strengthening partnerships in care (empowering knowledge and understanding, increased accountability to dialysis team); improving access to treatment (saving time and money, providing timely care and avoiding hospital); and preserving quality patient–provider interactions (enhancing face-to-face contact, clarifying expectations of access and use of data).

Conclusions:

Remote monitoring may increase patient knowledge about their kidney disease and its treatment, encourage accountability to the clinical team, enhance partnerships with clinicians, and improve access to treatment and timely care. It is also important to ensure that remote monitoring does not replace face-to-face clinical contact with clinicians.

Socioeconomic Factors and Racial and Ethnic Differences in the Initiation of Home Dialysis

Rationale & Objective

Home dialysis has been underused in the United States, especially among minority groups. We investigated whether adjustment for socioeconomic factors would attenuate racial/ethnic differences in the initiation of home dialysis.

Study Design

Retrospective observational cohort study.

Setting & Population

Adult patients in the US Renal Data System who initiated dialysis on day 1 with either in-center hemodialysis (HD), home HD (HHD), or peritoneal dialysis (PD) from 2005 to 2013.

Predictor

Race/ethnicity: non-Hispanic white, Hispanic, black, or Asian.

Outcome

Initiating dialysis with PD versus in-center HD and HHD versus in-center HD for each minority group compared with non-Hispanic whites.

Analytical Approach

Odds ratios and 95% CIs estimated by logistic regression.

Results

Of 523,526 patients, 55% were white, 28% were black, 13% were Hispanic, and 4% were Asian; 8% started dialysis on PD, and 0.1%, on HHD. In unadjusted analyses, blacks and Hispanics were 30% and 19% less likely and Asians were 31% more likely to start on PD than whites. The differences narrowed when fully adjusted for demographic, medical, and socioeconomic factors. Adjustment for socioeconomic factors reduced these differences between white and black, Hispanic, and Asian patients by 13%, 28%, and 1%, respectively. Blacks were just as likely and Hispanics and Asians were less likely to start on HHD than whites. This did not change appreciably when fully adjusted for demographic, medical, and socioeconomic factors.

Limitations

No data for physician and patient preferences or modality education.

Conclusions

Black and Hispanic patients are less likely to start on PD than white patients, attributable partly, though not completely, to socioeconomic factors. Hispanics and Asians are less likely to start on HHD than whites. This was materially unaffected by socioeconomic factors. More research is needed to determine whether urgent-start PD programs and transitional care units in socioeconomically disadvantaged areas might reduce these disparities and increase home dialysis use among all groups.

An opportunity for improved engagement and transparency: A systematic review of renal dialysis cost effectiveness and discrete choice experiment studies

Much attention is given to patient and provider engagement, cost, and quality. Nephrology is in a unique position to examine the intersection of these issues given kidney dialysis is delivered at a high cost to chronically ill patients. Annual dialysis treatments in Canada range from $56,000-$107,000 per patient dependent on modality. Economists quantify the preferred modality by calculating cost effectiveness through quality-adjusted life years or determining utilization through Discrete Choice Experiments (DCEs). Cost-effectiveness studies identify peritoneal dialysis as the most economical, yet it is the least used. Discrete choice experiments address patient preferences but rarely include cost attributes. This presents a unique paradigm: cost studies do not include patient or physician perspectives, and DCEs do not consider cost. This systematic review of dialysis cost-effectiveness studies and DCEs identifies an opportunity to increase engagement and transparency by involving all care partners in assessing quality and cost.

Trends in Peritoneal Dialysis Use in the United States after Medicare Payment Reform

BACKGROUND AND OBJECTIVES

Peritoneal dialysis (PD) for ESKD is associated with similar mortality, higher quality of life, and lower costs compared with hemodialysis (HD), but has historically been underused. We assessed the effect of the 2011 Medicare prospective payment system (PPS) for dialysis on PD initiation, modality switches, and stable PD use.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

Using US Renal Data System and Medicare data, we identified all United States patients with ESKD initiating dialysis before (2006-2010) and after (2011-2013) PPS implementation, and observed their modality for up to 2 years after dialysis initiation. Using logistic regression models, we examined the associations between PPS and early PD experience (any PD 1-90 days after initiation), late PD use (any PD 91-730 days after initiation), and modality switches (PD-to-HD or HD-to-PD 91-730 days after initiation). We adjusted for patient, dialysis facility, and regional characteristics.

RESULTS

Overall, 619,126 patients with incident ESKD received dialysis at Medicare-certified facilities, 2006-2013. Observed early PD experience increased from 9.4% before PPS to 12.6% after PPS. Observed late PD use increased from 12.1% to 16.1%. In adjusted analyses, PPS was associated with increased early PD experience (odds ratio [OR], 1.51; 95% confidence interval [95% CI], 1.47 to 1.55; P<0.001) and late PD use (OR, 1.47; 95% CI, 1.45 to 1.50; P<0.001). In subgroup analyses, late PD use increased in part due to an increase in HD-to-PD switches among those without early PD experience (OR, 1.59; 95% CI, 1.52 to 1.66; P<0.001) and a decrease in PD-to-HD switches among those with early PD experience (OR, 0.92; 95% CI, 0.87 to 0.98; P=0.004).

CONCLUSIONS

More patients started, stayed on, and switched to PD after dialysis payment reform. This occurred without a substantial increase in transfers to HD.

Which factors determine treatment choices in patients with advanced kidney failure? a protocol for a co-productive, mixed methods study

INTRODUCTION

Kidney disease is common, affecting up to 1 in 10 of the adult population, and the numbers are expected to rise over the next decade. There are three main treatments that are available to patients with kidney disease: transplantation, dialysis and supportive care without dialysis. Dialysis can occur in a dialysis unit or in a person's home, but unit-based dialysis remains the most common initial treatment for patients in Wales. This is a cause for concern as most studies suggest that it is associated with the lowest quality of life and the highest mortality, and is a more expensive treatment option.This study aims to identify the factors that lead to patients choosing unit-based haemodialysis rather than home-based dialysis with a view to informing future changes in patient education and service commissioning in Wales. A secondary aim is to determine if the co-production of research leads to more sustainable services.

METHODS AND ANALYSIS

This mixed-method study taking place between October 2018 and September 2020 will use a sequential explanatory design whereby the descriptive quantitative cross-sectional analysis of linked health and administrative data sets inform qualitative data collection from patients, carers and health and care professionals. Qualitative findings will be used to interpret or explain quantitative descriptive results. Additional strands to the study include a review of materials and education provided to patients and an economic review of treatment modalities.

ETHICS AND DISSEMINATION

The study will be conducted in accordance with the principles expressed in the Declaration of Helsinki. It has full approval from Health and Care Research Wales Research Ethics Committee #5. As a co-productive study involving patients, clinicians, third sector partners and academics, findings from this study will be shared on a continual basis. Study results will be published in peer-reviewed journals and presented at national and international conferences.

Association of Scheduled vs Emergency-Only Dialysis With Health Outcomes and Costs in Undocumented Immigrants With End-stage Renal Disease

IMPORTANCE

In 40 of 50 US states, scheduled dialysis is withheld from undocumented immigrants with end-stage renal disease (ESRD); instead, they receive intermittent emergency-only dialysis to treat life-threatening manifestations of ESRD. However, the comparative effectiveness of scheduled dialysis vs emergency-only dialysis and the influence of treatment on health outcomes, utilization, and costs is uncertain.

OBJECTIVE

To compare the effectiveness of scheduled vs emergency-only dialysis with regard to health outcomes, utilization, and costs in undocumented immigrants with ESRD.

DESIGN, SETTING, AND PARTICIPANTS

Observational cohort study of 181 eligible adults with ESRD receiving emergency-only dialysis in Dallas, Texas, who became newly eligible and applied for private commercial health insurance in February 2015; 105 received coverage and were enrolled in scheduled dialysis; 76 were not enrolled in insurance for nonclinical reasons (eg, lack of capacity at a participating outpatient dialysis center) and remained uninsured, receiving emergency-only dialysis. We examined data on eligible persons during a 6-month period prior to enrollment (baseline period, August 1, 2014-January 31, 2015) until 12 months after enrollment (follow-up period, March 1, 2015-February 29, 2016), with an intervening 1-month washout period (February 2015). All participants were undocumented immigrants; self-reported data on immigration status was collected from Parkland Hospital electronic health records.

EXPOSURES

Enrollment in private health insurance coverage and scheduled dialysis.

MAIN OUTCOMES AND MEASURES

We used enrollment in health insurance and scheduled dialysis to estimate the influence of scheduled dialysis on 1-year mortality, utilization, and health care costs, using a propensity score-adjusted, intention-to-treat approach, including time-to-event analyses for mortality, difference-in-differences (DiD) negative binomial regression analyses for utilization, and DiD gamma generalized linear regression for health care costs.

RESULTS

Of 181 eligible adults with ESRD, 105 (65 men, 40 women; mean age, 45 years) received scheduled dialysis and 76 (38 men, 38 women; mean age, 52 years) received emergency-only dialysis. Compared with emergency-only dialysis, scheduled dialysis was significantly associated with reduced mortality (3% vs 17%, P = .001; absolute risk reduction, 14%; number needed to treat, 7; adjusted hazard ratio, 4.6; 95% CI, 1.2-18.2; P = .03), adjusted emergency department visits (-5.2 vs +1.1 visits/mo; DiD, -6.2; P < .001), adjusted hospitalizations (-2.1 vs -0.5 hospitalizations/6 months; DiD, -1.6; P < .001), adjusted hospital days (-9.2 vs +0.8 days/6 months; DiD, -9.9; P = .007), and adjusted costs (-$4316 vs +$1452 per person per month; DiD, -$5768; P < .001).

CONCLUSIONS AND RELEVANCE

In this study, scheduled dialysis was significantly associated with reduced 1-year mortality, health care utilization, and costs compared with emergency-only dialysis. Scheduled dialysis should be the universal standard of care for all individuals with ESRD in the United States.

Exploring Barriers and Potential Solutions in Home Dialysis: An NKF-KDOQI Conference Outcomes Report

Home dialysis therapy, including home hemodialysis and peritoneal dialysis, is underused as a modality for the treatment of chronic kidney failure. The National Kidney Foundation-Kidney Disease Outcomes Quality Initiative sponsored a home dialysis conference in late 2017 that was designed to identify the barriers to starting and maintaining patients on home dialysis therapy. Clinical, operational, policy, and societal barriers were identified that need to be overcome to ensure that dialysis patients have the freedom to choose their treatment modality. Education of patients and patient partners, as well as health care providers, about home dialysis therapy, if offered at all, is often provided in a cursory manner. Lack of exposure to home dialysis therapies perpetuates a lack of familiarity and thus a hesitancy to refer patients to home dialysis therapies. Patient and care partner support, both psychosocial and financial, is also critical to minimize the risk for burnout leading to dropout from a home dialysis modality. Thus, the facilitation of home dialysis therapy will require a systematic change in chronic kidney disease education and the approach to dialysis therapy initiation, the creation of additional incentives for performing home dialysis, and breakthroughs to simplify the performance of home dialysis modalities. The home dialysis work group plans to develop strategies to overcome these barriers to home dialysis therapy, which will be presented at a follow-up home dialysis conference.

Barriers to Education and Shared Decision Making in the Chronic Kidney Disease Population: A Narrative Review

PURPOSE OF REVIEW

Provision of education to inform decision making for renal replacement therapy (RRT) is a key component in the management of chronic kidney disease (CKD), yet patients report suboptimal satisfaction with the process of selecting a dialysis modality. Our purpose is to review the influencers of RRT decision making in the CKD population, which will better inform the process of shared decision making between clinicians and patients.

SOURCES OF INFORMATION

PubMed and Google Scholar.

METHODS

A narrative review was performed using the main terms "chronic kidney disease," "CKD," "dialysis," "review," "decision-making," "decision aids," "education," and "barriers." Only articles in English were accessed. The existing literature was critically analyzed from a theoretical and contextual perspective and thematic analysis was performed.

KEY FINDINGS

Eight common themes were identified as influencers for decision making. "Patient-focused" themes including social influence, values and beliefs, comprehension, autonomy and sociodemographics, and "clinician-focused" themes including screening, communication, and engagement. Early predialysis education and decision aids can effectively improve decision making. Patient-valued outcomes need to be more fully integrated into clinical guidelines.

LIMITATIONS

This is not a systematic review; therefore, no formal tool was utilized to evaluate the rigor and quality of studies included and findings may not be generalizable.

IMPLICATIONS

Standardized comprehensive RRT education programs through multidisciplinary health teams can help optimize CKD patient education and shared decision making. Involving patients in the research process itself and implementing patient values and preferences into clinical guidelines can help to achieve a patient-centered model of care.

Socioeconomic status and risk of kidney dysfunction: the Atherosclerosis Risk in Communities study

Background

There is strong evidence of an association between socioeconomic status (SES) and end-stage renal disease (ESRD). However, the association of SES with the risk of chronic kidney disease (CKD) and the rate of change in kidney function is unclear.

Methods

A cohort of 14 086 participants with an estimated glomerular filtration rate (eGFR) ≥60 mL/min/1.73 m2 at baseline in the Atherosclerosis Risk in Communities study (1987–89) were studied. The association of annual household income, educational attainment and neighborhood deprivation with incident ESRD, incident CKD and change in eGFR using four measurements over ∼23 years was assessed.

Results

A total of 432 participants developed ESRD and 3510 developed CKD over a median follow-up time of ∼23 years. After adjustment for demographics and baseline eGFR, the hazard ratio (HR) for incident ESRD compared with the high-income group was 1.56 [95% confidence interval (CI) 1.22–1.99 in the medium-income group and 2.30 (95% CI 1.75–3.02) in the low-income group (P-trend < 0.001), and for CKD was 1.10 (95% CI 1.01–1.20) in the medium-income group and 1.30 (95% CI 1.17–1.44) in the low-income group (P-trend < 0.001). After full adjustments, the HR for ESRD was 1.33 (95% CI 1.03–1.70) in the medium-income group and 1.50 (95% CI 1.14–1.98) in the low-income group (P-trend = 0.003) and for CKD was 1.01 (95% CI 0.92–1.10) in the medium-income group and 1.04 (95% CI 0.93–1.16) in the low-income group (P-trend = 0.50). The eGFR decline was 5% and 15% steeper in the medium- and low-income groups, respectively, after full adjustment (P-trend < 0.001). Results were similar, with lower educational attainment and higher neighborhood deprivation being associated with adverse outcomes.

Conclusions

SES (annual household income, educational attainment or neighborhood deprivation) was associated not only with ESRD risk but also with eGFR decline, although the association with CKD appeared weaker.
