Recruitment and training for home hemodialysis: experience and lessons from the Nocturnal Dialysis Trial

Greater haemodialysis exposure ('quotidian haemodialysis') has different mortality associations by patient age group

Background

Worldwide, most people requiring kidney replacement therapy receive haemodialysis (HD) three times per week. Greater HD time and/or frequency may improve survival, but implementation requires understanding potential benefits across the range of patients.

Methods

Using data from the Australia and New Zealand Dialysis and Transplant Registry, we assessed whether quotidian HD (defined as >3 sessions/week and/or >5 h/session) was associated with reduced mortality in adult patients. The primary outcome of all-cause mortality was analysed by a time-varying Cox proportional hazards model with quotidian HD as the exposure of interest.

Results

Of 24 138 people who received HD between 2011 and 2019, 2632 (10.9%) received quotidian HD at some stage. These patients were younger, more likely male and more likely to receive HD at home. Overall, quotidian versus standard HD was associated with a decreased risk for all-cause mortality {crude hazard ratio [HR] 0.50 [95% confidence interval (CI) 0.45-0.56]}, but an interaction between quotidian HD and age was identified (P = .005). Stratified by age groups and splitting follow-up time where proportional hazards were violated, the corresponding HR compared with standard HD was 2.43 (95% CI 1.56-3.79) for people >75 years of age in the first year of quotidian HD, 1.52 (95% CI 0.89-2.58) for 1-3 years and 0.95 (95% CI 0.51-1.78) for ≥3 years. There was no significant survival advantage in younger people.

Conclusions

Although quotidian HD conferred survival benefit in crude analyses, people ≥75 years of age had greater mortality with quotidian HD than standard HD. The mortality benefit in younger people was attenuated when adjusted for known confounders.

Systems Innovations to Increase Home Dialysis Utilization

Globally, there is an interest to increase home dialysis utilization. The most recent United States Renal Data System (USRDS) data report that 13.3% of incident dialysis patients in the United States are started on home dialysis, while most patients continue to initiate KRT with in-center hemodialysis. To effect meaningful change, a multifaceted innovative approach will be needed to substantially increase the use of home dialysis. Patient and provider education is the first step to enhance home dialysis knowledge awareness. Ideally, one should maximize the number of patients with CKD stage 5 transitioning to home therapies. If this is not possible, infrastructures including transitional dialysis units and community dialysis houses may help patients increase self-care efficacy and eventually transition care to home. From a policy perspective, adopting a home dialysis preference mandate and providing financial support to recuperate increased costs for patients and providers have led to higher uptake in home dialysis. Finally, respite care and planned home-to-home transitions can reduce the incidence of transitioning to in-center hemodialysis. We speculate that an ecosystem of complementary system innovations is needed to cause a sufficient change in patient and provider behavior, which will ultimately modify overall home dialysis utilization.

Patient Survival With Extended Home Hemodialysis Compared to In-Center Conventional Hemodialysis

Introduction

More frequent and/or longer hemodialysis (HD) has been associated with improvements in numerous clinical outcomes in patients on dialysis. Home HD (HHD), which allows more frequent and/or longer dialysis with lower cost and flexibility in treatment planning, is not widely used worldwide. Although, retrospective studies have indicated better survival with HHD, this issue remains controversial. In this multicenter study, we compared thrice-weekly extended HHD with in-center conventional HD (ICHD) in a large patient population with a long-term follow-up.

Methods

We matched 349 patients starting HHD between 2010 and 2014 with 1047 concurrent patients on ICHD by using propensity scores. Patients were followed-up with from their respective baseline until September 30, 2018. The primary outcome was overall survival. Secondary outcomes were technique survival; hospitalization; and changes in clinical, laboratory, and medication parameters.

Results

The mean duration of dialysis session was 418 ± 54 minutes in HHD and 242 ± 10 minutes in patients on ICHD. All-cause mortality rate was 3.76 and 6.27 per 100 patient-years in the HHD and the ICHD groups, respectively. In the intention-to-treat analysis, HHD was associated with a 40% lower risk for all-cause mortality than ICHD (hazard ratio [HR] = 0.60; 95% confidence interval [CI] 0.45 to 0.80; P < 0.001). In HHD, the 5-year technical survival was 86.5%. HHD treatment provided better phosphate and blood pressure (BP) control, improvements in nutrition and inflammation, and reduction in hospitalization days and medication requirement.

Conclusion

These results indicate that extended HHD is associated with higher survival and better outcomes compared to ICHD.

Setting Up Home Dialysis Programs: Now and in the Future

Home dialysis utilization has been growing in the United States over the past decade but still lags behind similar socioeconomic nations. More than half of dialysis facilities in the United States either are not licensed to offer home dialysis or, despite a license, have no patients dialyzing at home, and many programs have a relatively small census. Multiple stakeholders, including patients, health care providers, and payers, have identified increased home dialysis use as an important goal. To realize these goals, nephrologists and kidney care professionals need a sound understanding of the key considerations in home dialysis center operation. In this review, we outline the core domains required to set up and operate a home dialysis program in the United States now and in the future.

Interventions for fatigue in people with kidney failure requiring dialysis

BACKGROUND

Fatigue is a common and debilitating symptom in people receiving dialysis that is associated with an increased risk of death, cardiovascular disease and depression. Fatigue can also impair quality of life (QoL) and the ability to participate in daily activities. Fatigue has been established by patients, caregivers and health professionals as a core outcome for haemodialysis (HD).

OBJECTIVES

We aimed to evaluate the effects of pharmacological and non-pharmacological interventions on fatigue in people with kidney failure receiving dialysis, including HD and peritoneal dialysis (PD), including any setting and frequency of the dialysis treatment.

SEARCH METHODS

We searched the Cochrane Kidney and Transplant Register of Studies up to 18 October 2022 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Registry Platform (ICTRP) Search Portal and ClinicalTrials.gov.

SELECTION CRITERIA

Studies evaluating pharmacological and non-pharmacological interventions affecting levels of fatigue or fatigue-related outcomes in people receiving dialysis were included. Studies were eligible if fatigue or fatigue-related outcomes were reported as a primary or secondary outcome. Any mode, frequency, prescription, and duration of therapy were considered.

DATA COLLECTION AND ANALYSIS

Three authors independently extracted data and assessed the risk of bias. Treatment estimates were summarised using random effects meta-analysis and expressed as a risk ratio (RR) or mean difference (MD), with a corresponding 95% confidence interval (CI) or standardised MD (SMD) if different scales were used. Confidence in the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.

MAIN RESULTS

Ninety-four studies involving 8191 randomised participants were eligible. Pharmacological and non-pharmacological interventions were compared either to placebo or control, or to another pharmacological or non-pharmacological intervention. In the majority of domains, risks of bias in the included studies were unclear or high. In low certainty evidence, when compared to control, exercise may improve fatigue (4 studies, 217 participants (Iowa Fatigue Scale, Modified Fatigue Impact Scale, Piper Fatigue Scale (PFS), or Haemodialysis-Related Fatigue scale score): SMD -1.18, 95% CI -2.04 to -0.31; I2 = 87%) in HD. In low certainty evidence, when compared to placebo or standard care, aromatherapy may improve fatigue (7 studies, 542 participants (Fatigue Severity Scale (FSS), Rhoten Fatigue Scale (RFS), PFS or Brief Fatigue Inventory score): SMD -1.23, 95% CI -1.96 to -0.50; I2 = 93%) in HD. In low certainty evidence, when compared to no intervention, massage may improve fatigue (7 studies, 657 participants (FSS, RFS, PFS or Visual Analogue Scale (VAS) score): SMD -1.06, 95% CI -1.47, -0.65; I2 = 81%) and increase energy (2 studies, 152 participants (VAS score): MD 4.87, 95% CI 1.69 to 8.06, I2 = 59%) in HD. In low certainty evidence, when compared to placebo or control, acupressure may reduce fatigue (6 studies, 459 participants (PFS score, revised PFS, or Fatigue Index): SMD -0.64, 95% CI -1.03 to -0.25; I2 = 75%) in HD. A wide range of heterogenous interventions and fatigue-related outcomes were reported for exercise, aromatherapy, massage and acupressure, preventing our capability to pool and analyse the data. Due to the paucity of studies, the effects of pharmacological and other non-pharmacological interventions on fatigue or fatigue-related outcomes, including non-physiological neutral amino acid, relaxation with or without music therapy, meditation, exercise with nandrolone, nutritional supplementation, cognitive-behavioural therapy, ESAs, frequent HD sections, home blood pressure monitoring, blood flow rate reduction, serotonin reuptake inhibitor, beta-blockers, anabolic steroids, glucose-enriched dialysate, or light therapy, were very uncertain. The effects of pharmacological and non-pharmacological treatments on death, cardiovascular diseases, vascular access, QoL, depression, anxiety, hypertension or diabetes were sparse. No studies assessed tiredness, exhaustion or asthenia. Adverse events were rarely and inconsistently reported.

AUTHORS' CONCLUSIONS

Exercise, aromatherapy, massage and acupressure may improve fatigue compared to placebo, standard care or no intervention. Pharmacological and other non-pharmacological interventions had uncertain effects on fatigue or fatigue-related outcomes in people receiving dialysis. Future adequately powered, high-quality studies are likely to change the estimated effects of interventions for fatigue and fatigue-related outcomes in people receiving dialysis.

Home hemodialysis technique survival: insights and challenges

Home hemodialysis (HHD) offers several clinical, quality of life and cost-saving benefits for patients with end-stage kidney disease. While uptake of this modality has increased in recent years, its prevalence remains low and high rates of discontinuation remain a challenge. This comprehensive narrative review aims to better understand what is currently known about technique survival in HHD patients, elucidate the clinical factors that contribute to attrition and expand on possible strategies to prevent discontinuation. With increasing efforts to encourage home modalities, it is imperative to better understand technique survival and find strategies to help maintain patients on the home therapy of their choosing. It is crucial to better target high-risk patients, examine ideal training practices and identify practices that are potentially modifiable to improve technique survival.

Home dialysis: conclusions from a Kidney Disease: Improving Global Outcomes (KDIGO) Controversies Conference

Home dialysis modalities (home hemodialysis [HD] and peritoneal dialysis [PD]) are associated with greater patient autonomy and treatment satisfaction compared with in-center modalities, yet the level of home-dialysis use worldwide is low. Reasons for limited utilization are context-dependent, informed by local resources, dialysis costs, access to healthcare, health system policies, provider bias or preferences, cultural beliefs, individual lifestyle concerns, potential care-partner time, and financial burdens. In May 2021, KDIGO (Kidney Disease: Improving Global Outcomes) convened a controversies conference on home dialysis, focusing on how modality choice and distribution are determined and strategies to expand home-dialysis use. Participants recognized that expanding use of home dialysis within a given health system requires alignment of policy, fiscal resources, organizational structure, provider incentives, and accountability. Clinical outcomes across all dialysis modalities are largely similar, but for specific clinical measures, one modality may have advantages over another. Therefore, choice among available modalities is preference-sensitive, with consideration of quality of life, life goals, clinical characteristics, family or care-partner support, and living environment. Ideally, individuals, their care-partners, and their healthcare teams will employ shared decision-making in assessing initial and subsequent kidney failure treatment options. To meet this goal, iterative, high-quality education and support for healthcare professionals, patients, and care-partners are priorities. Everyone who faces dialysis should have access to home therapy. Facilitating universal access to home dialysis and expanding utilization requires alignment of policy considerations and resources at the dialysis-center level, with clear leadership from informed and motivated clinical teams.

Main Barriers to the Introduction of a Home Haemodialysis Programme in Poland: A Review of the Challenges for Implementation and Criteria for a Successful Programme

Introduction: Home dialysis in Poland is restricted to the peritoneal dialysis (PD) modality, with the majority of dialysis patients treated using in-centre haemodialysis (ICHD). Home haemodialysis (HHD) is an additional home therapy to PD and provides an attractive alternative to ICHD that combines dialysis with social distancing; eliminates transportation needs; and offers clinical, economic, and quality of life benefits. However, HHD is not currently provided in Poland. This review was performed to provide an overview of the main barriers to the introduction of a HHD programme in Poland. Main findings: The main high-level barrier to introducing HHD in Poland is the absence of specific health legislation required for clinician prescribing of HHD. Other barriers to overcome include clear definition of reimbursement, patient training and education (including infrastructure and experienced personnel), organisation of logistics, and management of complications. Partnering with a large care network for HHD represents an alternative option to payers for the provision of a new HHD service. This may reduce some of the barriers which need to be overcome when compared with the creation of a new HHD service and its supporting network due to the pre-existing infrastructure, processes, and staff of a large care network. Conclusions: Provision of HHD is not solely about the provision of home treatment, but also the organisation and definition of a range of support services that are required to deliver the service. HHD should be viewed as an additional, complementary option to existing dialysis modalities which enables choice of modality best suited to a patient’s needs.

Experience in Spain with the first patients in home hemodialysis treated with low-flow dialysate monitors

Home hemodialysis (HHD) with low-flow dialysate devices has gained popularity in recent years due to its simple design, portability, and ability to provide greater freedom of movement for our patients. However, there are doubts about the adequacy that this technology offers, since it uses monitors with low-flow bath and lactate. The aim of this study was to demonstrate the clinical benefits of low-flow HHD with the NxStage System One® recently introduced in Spain. We present the results of an observational, retrospective cohort study that included the first patients who started short daily HHD with this device in 12 Spanish centers. We analyzed the evolution of 86 patients at 0, 6 and 12 months, including data related to prescription, and evolution of biochemical parameters related to dialysis dose, anemia, mineral-bone metabolism; evolution of residual renal function, medication usage, and causes of withdrawal during the followup. We were able to demonstrate that this NxStage System One® monitor, in patients with HHD, have provided an adequate dialysis dose, with optimal ultrafiltration rate, with improvement of main biochemical markers of dialysis adequacy. The usage of this technique was associated to a decrease of antihypertensive drugs, phosphate binders and erythropoietin agents, with very good results both patient and technique survival. The simplicity of the technique, together with its good clinical outcomes, should facilitate the growth and utilization of HHD, both in incident and prevalent patients.

The need for individualizing teaching and assurance of knowledge transmission to patients training for home dialysis

Patients have varied learning styles and this has implications for home haemodialysis (HHD). Assessment tools directed toward understanding these styles remains understudied. As a consequence, this may lead to substandard retention rates or adverse events in HHD programs. As part of a continuous quality improvement initiative we have aimed to improve our understanding of patient learning styles and consequently tailor home dialysis training to individuals. To objectively determine knowledge translation and comprehension, irrespective of learning styles, we have introduced an objective structured clinical examination (OSCE). This assessment tool allows for further refinement of educational priorities by highlighting both deficiencies and strengths. Thereafter, an exit OSCE ensures patients attain an acceptable standard to complete home haemodialysis independently. We hope this tool will help shape future training criteria for HHD programs and consequently reduce adverse event rates.

Incremental and Personalized Hemodialysis Start: A New Standard of Care

Introduction

Incremental hemodialysis (iHD) may attenuate “dialysis shock” and reduce costs, preserving quality of life. It is considered difficult to reconcile with HD wards’ routine; fear of underdialysis and increasing mortality are additional concerns. The aim of this study was to evaluate mortality, morbidity, and costs in a large HD ward where iHD is the standard of HD start.

Methods

This observational study included all incident HD patients in 2017 to 2021, stratified according to HD start: iHD (1–2 sessions/wk), decremental HD (dHD, 3 sessions/wk at start, later reduced), or standard (3 sessions/wk). Results were compared with data recorded in the same unit before the incremental program (2015–2017) and with a propensity score-matched cohort from the French Renal Epidemiology and Information Network (REIN) registry.

Results

A total of 158 patients started HD in 2017 to 2021, 57.6% on iHD, 8.9% dHD, and 33.5% standard HD schedule. Patients on the standard schedule had lower initial estimated glomerular filtration rate (eGFR) (5 vs. 7 ml/min per 1.72 m², P = 0.003). We found no survival differences according to period of start (same center) and propensity score matching (REIN). Patients intensively followed in the pre-HD period were more likely to start on iHD-dHD. Persistence on iHD-dHD was about 50% at 1 year and 35% at 2 years. Hospitalization rates and time to first hospitalization or death did not differ between the schedules. The iHD-dHD policy allowed a 16% cost saving, even accounting for supplemental biochemical tests.

Conclusion

Our study reveals that iHD can be a new standard of care, as it is safe and feasible in up to two-thirds of patients on incident HD.

Experience in Spain with the first patients in home hemodialysis treated with low-flow dialysate monitors

Home hemodialysis (HHD) with low-flow dialysate devices has gained popularity in recent years due to its simple design, portability, and ability to provide greater freedom of movement for our patients. However, there are doubts about the adequacy that this technology offers, since it uses monitors with low-flow bath and lactate.

Risk of hospitalization, technique failure, and death with increased training duration in 3-days-a-week home hemodialysis

INTRODUCTION

Quality training is a core component of successful home hemodialysis (HHD) and training duration varies significantly between dialysis centers as well as at the patient level. This study aimed to assess the adverse outcomes associated with HHD training duration.

METHODS

All HHD patients successfully trained in a single dialysis center between January 2005 and July 2017 were included. A multivariable multiple-events (Andersen-Gill) survival model was built to evaluate the association between training time and main adverse events, including hospitalizations, technique failure, and death on HHD. Potential confounding factors were defined a priori (age, diabetes, coronary artery disease, and year of training start). Adjusted risk of vascular interventions (arteriovenous fistula angioplasties and central venous catheter replacements) was assessed as the secondary outcome in a negative binomial regression.

FINDINGS

Forty-eight patients were included in the study. Median HHD training duration was 86 (67-108) days, using a thrice weekly training schedule. Over a follow-up median time of 2.0 (0.7-3.3) years, three patients died while on HHD, 10 had a definitive transfer to HD, and 18 experienced a least 1 hospitalization (38 hospitalizations in total). Training duration was associated with a higher risk of hospitalization, technique failure, and death in unadjusted (hazard ratio [HR] 1.16 per month, 95% confidence interval [CI] 1.08-1.24) and adjusted multiple events model (HR 1.21, 95% CI 1.04-1.43). Risk of vascular access intervention was also significantly higher with increased training time (adjusted incidence rate ratio 1.31, 95% CI 1.03-1.64, per training month).

DISCUSSION

In this single-center observational study, HHD training duration was associated with a higher risk of adverse events including, death, technique failure, hospitalizations, and vascular access intervention. Enhanced clinical follow-up and home support should be offered to these more vulnerable patients to mitigate this heightened risk.

Survival comparisons in home hemodialysis: Understanding the present and looking to the future

A number of studies have compared relative survival for home hemodialysis patients (including longer hours/more frequent schedules) and other forms of renal replacement therapy. While informative, many of these studies have been limited by issues pertaining to their observational design including selection bias and residual confounding. Furthermore the few randomized controlled trials that have been conducted have been underpowered to detect a survival difference. Finally, in the face of a growing recognition of the value of patient-important outcomes beyond survival, the focus of comparisons between dialysis modalities may be changing. In this review, we will discuss the determinants of survival for patients receiving home hemodialysis and address the various studies that have compared relative survival for differing home hemodialysis schedules to each of in-center hemodialysis, peritoneal dialysis and transplantation. We will conclude this review by discussing whether there is an ongoing role for survival analyses in home hemodialysis.

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.

Strategic Planning for Starting or Expanding a Home Hemodialysis Program

The American Advancing Kidney Health Initiative has renewed interest in home hemodialysis (HHD). Many perceived barriers exist for adoption of HHD despite well-reported clinical benefits. A well-designed program ensures patient success further engaging more patients. The initial planning regarding the surrounding patient population, stakeholders, economics, and physical location is essential. The services offered including modality education and different kinds of HHD modalities depend on local expertise and economics. The program should fulfill conditions for coverage requirements for personnel, physical infrastructure, and quality metrics to begin operations. The patient recruitment is facilitated by a patient-centric modality education program developed by the multidisciplinary team. If the patient is interested, a training schedule should be discussed with the patient and caregiver. A system to ensure remote patient monitoring, respite care, and 24 hours on-call availability should be established. These practical considerations ensure initial success and future growth of the program.

Physical Infrastructure and Integrated Governance Structure for Home Hemodialysis

In view of the growing enthusiasm for home dialysis use, new dialysis centers may build or expend their home hemodialysis program in the next few years. This review will discuss the main challenges faced by small and large home hemodialysis programs in terms of physical spaces, human resource, training considerations, and overall governance. We will elaborate on the inclusion of home hemodialysis in the kidney replacement therapy care continuum, with a specific interest for collaboration and transition between peritoneal dialysis and home hemodialysis programs.

Peritoneal dialysis (PD) technique training: what features influence learning time?

BACKGROUND

Within peritoneal dialysis (PD) complications, peritonitis remains a primary challenge for the long-term success of the technique. Proper technique training is essential, since it reduces peritonitis rates, but the adequacy of training has not been standardized. Furthermore, factors influencing training duration have not been well identified.

METHODS

We retrospectively analyzed all consecutive training sessions of incident PD patients in our Unit from January 2001 to December 2018.

RESULTS

Our analysis included 135 patients, 25.9% were diabetic and median Charlson index (CCI) was 4 (IQR 2-6). Above 13 sessions was chosen as the cut off between usual and prolonged training, as it was our cohort's 75th percentile: 23% (31) had an extended training duration as per our study definition and 77% (104) had a usual training duration. The number of training sessions required increased with age (Spearman Rho 0.404; p = 0.000001), diabetic status (p = 0.001), unemployment status (p = 0.046) and CCI (Spearman Rho 0.369; p = 0.00001). Neither gender, cohabitation status, scheduled PD start, education level nor referral origin, were significant factors impacting training duration. Requiring longer training (> 13 sessions) was a significant risk factor for higher peritonitis risk, but extended training was not related to a shorter technique survival.

CONCLUSION

Number of PD training sessions depends on the patient's age and comorbidities, but is not related to social, educational or employment status. Prolonged training duration was a statistically significant predictor of higher peritonitis risk, but it was not related to shorter permanence in PD in our series. Identifying these patients since the training period would be useful to adapt training schedule as an early prevention strategy to minimize the risk of peritonitis and plan a preemptive retraining.

Going Home: Access for Home Modalities

The cost and health burden of ESRD continues to increase globally. Total Medicare expenditure on dialysis has increased from 229 million USD in 1973 to 35.4 billion USD in 2016. Dialysis access can represent almost a tenth of these costs. Central venous catheters have been recognized as a significant factor driving costs and mortality in this population. Home dialysis, which includes peritoneal dialysis and home hemodialysis, is an effective way of reducing costs related to renal replacement therapy, reducing central venous catheter usage and in many cases improving the clinical and psychosocial aspects of patients' health. Addressing access-related issues for peritoneal dialysis, urgent-start peritoneal dialysis and home hemodialysis can have impact on the success of home dialysis. This article reviews issues related to dialysis access for home therapies.

Targeted Education ApproaCH to improve Peritoneal Dialysis Outcomes (TEACH-PD): A feasibility study

BACKGROUND

There is substantial variation in peritonitis rates across peritoneal dialysis (PD) units globally. This may, in part, be related to the wide variability in the content and delivery of training for PD nurse trainers and patients.

AIM

The aim of this study was to test the feasibility of implementing the Targeted Education ApproaCH to improve Peritoneal Dialysis Outcomes (TEACH-PD) curriculum in real clinical practice settings.

METHODS

This study used mixed methods including questionnaires and semi-structured interviews (pretraining and post-training) with nurse trainers and patients to test the acceptability and usability of the PD training modules implemented in two PD units over 6 months. Quantitative data from the questionnaires were analysed descriptively. Interviews were analysed using thematic analysis.

RESULTS

Ten PD trainers and 14 incident PD patients were included. Mean training duration to complete the modules were 10.9 h (range 6-17) and 24.9 h (range 15-35), for PD trainers and patients, respectively. None of the PD patients experienced PD-related complications at 30 days follow-up. Three (21%) patients were transferred to haemodialysis due to non-PD-related complications. Ten trainers and 14 PD patients participated in the interviews. Four themes were identified including use of adult learning principles (trainers), comprehension of online modules (trainers), time to complete the modules (trainers) and patient usability of the manuals (patient).

CONCLUSION

This TEACH-PD study has demonstrated feasibility of implementation in a real clinical setting. The outcomes of this study have informed refinement of the TEACH-PD modules prior to rigorous evaluation of its efficacy and cost-effectiveness in a large-scale study.

The Potential Burden of Home Dialysis on Patients and Caregivers: A Narrative Review

Purpose of review:

Home dialysis modalities offer several benefits for patients with end-stage kidney disease when compared with facility-based thrice-weekly hemodialysis. To increase uptake of home dialysis, many centers are encouraging a “home-first” approach. However, it is important to appreciate that “one size may not fit all” and that dialysis modality selection is a complex decision that needs to be individualized. The purpose of this review was to explore aspects associated with home dialysis that may be associated with burden for patients and their caregivers and to discuss strategies to alleviate these concerns.

Sources of information:

Original research articles were identified from PubMed using search terms “peritoneal dialysis,” “home hemodialysis,” “home dialysis,” “barriers,” “quality of life” and “burden.”

Methods:

We performed a focused narrative review examining potential sources of burden with home dialysis therapies after conducting a critical appraisal of the literature and identifying the major recurring themes.

Key findings:

Home dialysis is associated with burden for certain patients. Indeed, some patients may experience ongoing concerns regarding the risks of adverse events and of inadequately performing dialysis on their own. Psychosocial issues affecting quality of life may also arise and include fear of social isolation, sleep disturbances, perceived financial burden, anxiety, and fatigue. Patients who depend on a caregiver may worry about creating a stressful home environment for their close ones. Furthermore, the demands associated with being a caregiver may lead to psychosocial distress in the caregivers themselves. All these factors may lead to burnout and consequently, therapy discontinuation necessitating an unplanned transition to in-center hemodialysis leading to adverse outcomes. However, certain strategies may help alleviate burden especially if concerns are identified early on.

Limitations:

As we did not apply any formal tool to assess the quality of the studies included, selection bias may have occurred. Nonetheless, we have attempted to provide a comprehensive review on the topic using numerous diverse studies and extensive review of the literature.

Implications:

Future studies should focus on better identifying patient priorities and strategies to facilitate dialysis modality selection and improve quality of life.

Nocturnal home hemodialysis with low-flow dialysate: Retrospective analysis of the first European patients

INTRODUCTION

Despite mounting evidence that increased frequency and duration of hemodialysis (HD) improves outcomes, less than 1% of HD patients worldwide receive nocturnal hemodialysis (NHD). Many perceived barriers exist to providing NHD and increasing its provision.

METHODS

A retrospective analysis of nocturnal therapy using a low-flow dialysate system in 4 European centers for a minimum of 12 months, with data collected on patient demographics, training times, safety features, medications, and biochemical parameters at baseline and at 6 and 12 months.

FINDINGS

Data were collected on 21 patients, with 12-month analysis available for 20 patients. Mean dialysis duration was 28 hours per week, with most dialysis on an alternate night regimen using 50-60 L of dialysate per session. All vascular access types were represented, and low molecular weight heparin was used as a bolus. All biochemical parameters met European standards, with a trend for improvement in standardized Kt/V, phosphate, hemoglobin, and albumin. There was a significant reduction in phosphate binder usage and a reduction in blood pressure medication. Training time was 9.6 sessions for independence at home, with 2 additional sessions to transition to NHD. Additional safety features included an alarmed drip tray under the cycler and moisture sensors under the venous needle (all patients used dual-cannulation technique). No patient safety events were reported.

DISCUSSION

These data support the use of a low-flow dialysate system for provision of NHD at home. Biochemical parameters were good, medication burden was reduced at 12 months, and all patients received more than double the duration of HD provided in standard in-center units. While patient numbers were small, low-flow dialysis in this cohort was both effective and safe. Use of this alternative HD system could reduce some of the barriers to NHD, increasing the uptake of therapy in Europe, and improving long-term patient outcomes.

Survival Comparisons of Home Dialysis Versus In-Center Hemodialysis: A Narrative Review

Purpose of review:

Many observational studies have demonstrated a survival benefit with home dialysis compared with in-center dialysis; however, results have been conflicting. The purpose of this review was to identify pitfalls and limitations in existing literature and examine the challenges of studying home and in-center dialysis populations.

Original research articles were identified from MEDLINE using search terms “in-center hemodialysis,” “home hemodialysis,” “conventional hemodialysis,” “nocturnal hemodialysis,” and “short daily hemodialysis.”

Methods:

A focused review and critical appraisal of existing home versus in-center hemodialysis survival literature was conducted to identify potential causes for variability in the observed survival outcomes.

Key findings:

The controversy in existing literature stems from the challenges of randomizing patients to home versus in-center hemodialysis modalities, and therefore a reliance on observational comparisons for study. In many cases, these observational analyses have been limited by selection bias (variabilities in populations included, inclusion of both incident and prevalent cohorts, and variabilities in dialysis intensity), as well as residual confounding. Furthermore, the studies that do exist lack generalizability in many cases.

Limitations:

There are few randomized controlled trials examining the survival benefit of home versus in-center hemodialysis and existing observational studies are often limited by bias and reduced generalizability. These limitations comprise the body of this review.

Implications:

This review examines challenges surrounding survival comparisons with home versus in-center hemodialysis and identify important directions for future study.

Nocturnal hemodialysis: improved quality of life and patient outcomes

Conventional hemodialysis is associated with high morbidity and mortality rates, as well as a reduced quality of life. There is a growing interest in the provision of more intensive hemodialysis, due to associated benefits in terms of reduced cardiovascular morbidity, better regulation of mineral metabolism, as well as its impact on quality of life measures, fertility, and sleep. Nocturnal hemodialysis, both in center and at home, allows the delivery of more intensive hemodialysis. This review discusses the benefits of nocturnal hemodialysis and evaluates the evidence based on available literature.

Buttonhole versus Stepladder Cannulation for Home Hemodialysis: A Multicenter, Randomized, Pilot Trial

BACKGROUND AND OBJECTIVES

Canadian home hemodialysis guidelines highlight the potential differences in complications associated with arteriovenous fistula (AVF) cannulation technique as a research priority. Our primary objective was to determine the feasibility of randomizing patients with ESKD training for home hemodialysis to buttonhole versus stepladder cannulation of the AVF. Secondary objectives included training time, pain with needling, complications, and cost by cannulation technique.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

All patients training for home hemodialysis at seven Canadian hospitals were assessed for eligibility, and demographic information and access type was collected on everyone. Patients who consented to participate were randomized to buttonhole or stepladder cannulation technique. Time to train for home hemodialysis, pain scores on cannulation, and complications over 12 months was recorded. For eligible but not randomized patients, reasons for not participating in the trial were documented.

RESULTS

Patient recruitment was November 2013 to November 2015. During this time, 158 patients began training for home hemodialysis, and 108 were ineligible for the trial. Diabetes mellitus as a cause of ESKD (31% versus 12%) and central venous catheter use (74% versus 6%) were more common in ineligible patients. Of the 50 eligible patients, 14 patients from four out of seven sites consented to participate in the study (28%). The most common reason for declining to participate was a strong preference for a particular cannulation technique (33%). Patients randomized to buttonhole versus stepladder cannulation required a shorter time to complete home hemodialysis training. We did not observe a reduction in cannulation pain or complications with the buttonhole method. Data linkages for a formal cost analysis were not conducted.

CONCLUSIONS

We were unable to demonstrate the feasibility of conducting a randomized, controlled trial of buttonhole versus stepladder cannulation in Canada with a sufficient number of patients on home hemodialysis to be able to draw meaningful conclusions.

An Intervention Design: Supporting Skills Development for Peritoneal Dialysis Trainers

BACKGROUND

Peritoneal dialysis (PD) is a home-based therapy where nurses train patients in its use. There has been no published randomized controlled trial (RCT) evaluating any specific protocol for nurses delivering PD training. A standardized education package based upon the best available evidence and utilizing modern educational practices may lead to improved patient outcomes. The aim is to develop a standardized, evidence-based curriculum for PD trainers and patients aligned with guidelines from the International Society for Peritoneal Dialysis (ISPD), using best practice pedagogy.

METHODS

A literature search and clinical audit were conducted to identify current practice patterns and best practice. Results were reviewed by a focus group of practitioners comprising PD nurses, nephrologists, consumers, a medical education expert, and an eLearning expert. From this, a training curriculum and modules were developed.

RESULTS

A comprehensive PD training curriculum has been developed, which includes modules for training PD nurses (trainers) and patient training manuals. The package comprises 2 introductory modules and 2 clinical case modules. The curriculum is designed for both interactive digital media (trainers) and traditional paper-based teaching with practical demonstrations (patients). Assessment is also addressed.

CONCLUSION

The need for the development of a comprehensive and standardized curriculum for PD nurse trainers and their patients was confirmed. This paper outlines the process of the development of this curriculum. Pilot testing of the modules was launched in late 2017 to examine feasibility, and planning has commenced for a RCT in 2019 to investigate the effect of the modules on clinical outcomes, and their wider application across Australia and New Zealand.

Antibiotic Dosing in Chronic Kidney Disease and End-Stage Renal Disease: A Focus on Contemporary Challenges

Infections are an important cause of morbidity and mortality among patients with chronic kidney disease. Therefore, appropriate antibiotic dosing is imperative to achieve positive patient outcomes while minimizing antibiotic dose-related toxicity. Accurately assessing renal function and determining the influence of renal replacement therapy on antibiotic clearance makes drug dosing in this patient population challenging. Furthermore, as technological advances in hemodialysis and peritoneal dialysis occur, research incorporating newer dialysis parameters to guide drug dosing may not be readily available. Currently, there are limited data to guide drug dosing in the setting of automated peritoneal dialysis, short daily hemodialysis, and nocturnal hemodialysis. Antibiotic-dosing recommendations should be carefully evaluated considering the accuracy of the renal function assessment, the similarity of the operating characteristics of the renal replacement therapy studied compared with those being used, and whether the dosing strategy takes advantage of the pharmacodynamic profile of the antibiotic under consideration. After implementing the antibiotic-dosing regimen, therapeutic drug monitoring should occur when possible along with careful monitoring for antibiotic efficacy and safety.

Home hemodialysis treatment and outcomes: retrospective analysis of the Knowledge to Improve Home Dialysis Network in Europe (KIHDNEy) cohort

Background

Utilization of home hemodialysis (HHD) is low in Europe. The Knowledge to Improve Home Dialysis Network in Europe (KIHDNEy) is a multi-center study of HHD patients who have used a transportable hemodialysis machine that employs a low volume of lactate-buffered, ultrapure dialysate per session. In this retrospective cohort analysis, we describe patient factors, HHD prescription factors, and biochemistry and medication use during the first 6 months of HHD and rates of clinical outcomes thereafter.

Methods

Using a standardized digital form, we recorded data from 7 centers in 4 Western European countries. We retained patients who completed ≥6 months of HHD. We summarized patient and HHD prescription factors with descriptive statistics and used mixed modeling to assess trends in biochemistry and medication use. We also estimated long-term rates of kidney transplant and death.

Results

We identified 129 HHD patients; 104 (81%) were followed for ≥6 months. Mean age was 49 years and 66% were male. Over 70% of patients were prescribed 6 sessions per week, and the mean treatment duration was 15.0 h per week. Median HHD training duration was 2.5 weeks. Mean standard Kt/V_urea was nearly 2.7 at months 3 and 6. Pre-dialysis biochemistry was generally stable. Between baseline and month 6, mean serum bicarbonate increased from 23.1 to 24.1 mmol/L (P = 0.01), mean serum albumin increased from 36.8 to 37.8 g/L (P = 0.03), mean serum C-reactive protein increased from 7.3 to 12.4 mg/L (P = 0.05), and mean serum potassium decreased from 4.80 to 4.59 mmol/L (P = 0.01). Regarding medication use, the mean number of antihypertensive medications fell from 1.46 agents per day at HHD initiation to 1.01 agents per day at 6 months (P < 0.001), but phosphate binder use and erythropoiesis-stimulating agent dose were stable. Long-term rates of kidney transplant and death were 15.3 and 5.4 events per 100 patient-years, respectively.

Conclusions

Intensive HHD with low-flow dialysate delivers adequate urea clearance and good biochemical outcomes in Western European patients. Intensive HHD coincided with a large decrease in antihypertensive medication use. With relatively rapid training, HHD should be considered in more patients.

Screening of Cognitive Impairment in the Dialysis Population: A Scoping Review

BACKGROUND

Cognitive impairment in end-stage kidney disease patients on dialysis is increasingly common. This study aimed to review the practice of screening and to evaluate the evidence on cognitive impairment prevalence in this population.

METHODS

This scoping review of studies summarises the evidence on cognitive impairment in dialysis populations. The search included the Medline, CINAHL, Embase, PsycINFO, PubMed, and Cochrane Library databases for English-language articles published between 2000 and 2015. A total of 46 articles were reviewed.

RESULTS

The studies were of prospective observational design, with the majority conducted in the haemodialysis population. The reported prevalence of cognitive impairment ranged from 6.6 to 51%. Three screening tools were consistently used.

CONCLUSION

While cognitive impairment is recognised in the dialysis population, there is paucity of screening data. The design of prospective comparisons ideally includes established screening instruments, particularly the Montreal Cognitive Assessment, to determine the optimal results for this population. Translation of established screening tools to increase the inclusion of people from other cultural and language groups is required. Regular screening can enhance the timing to introduce home-based care support and advance care planning discussions.

How an ordeal becomes the norm: A qualitative exploration of experiences of self-cannulation in male home haemodialysis patients

OBJECTIVES

Despite home haemodialysis (HHD) being associated with significant health and psychosocial benefits, it remains an under-utilized dialysis modality for people with chronic kidney disease. Self-cannulation, where patients insert their own needles for dialysis, is a key component of HHD. Recent research suggests that the prospect of self-cannulation is a barrier for patients, but there is little research which examines why this is the case. The aim of this study was to explore male HHD patients' experiences and attitudes towards self-cannulation.

DESIGN

Qualitative methods were adopted to gather in-depth views from experienced HHD patients from a UK renal centre.

METHODS

Semi-structured interviews were conducted with eight male HHD patients (HHD duration: 12-55 months). During the interview, the researcher elicited participants' lived experience of self-cannulation. Topics included the decision to self-cannulate and the impact of self-cannulation on the patient. The data collected were analysed using interpretative phenomenological analysis.

RESULTS

The findings from this study elucidate the process of how self-cannulation changed from an ordeal to the norm in these participants' lives. The central theme from these interviews is that 'becoming a person who self-cannulates is a process'. Three super-ordinate themes were discussed that relate to this central theme: 'gaining control', 'building confidence', and 'becoming the norm'.

CONCLUSIONS

The findings from this study suggest that some patients' initial fears of self-cannulation can be overcome. These findings offer health care professionals and patients alike a greater understanding of how patients who self-cannulate conceptualize it and its role in their mental and physical health. Statement of contribution What is already known on this subject? Home haemodialysis is a cost-effective form of renal replacement therapy which is under-utilized in the United Kingdom. Home haemodialysis is associated with positive health outcomes. Self-cannulation is noted as a barrier to home haemodialysis. What does this study add? Describes the process by which male dialysis patients became proficient in self-cannulation. Highlights psychological mechanisms which may facilitate and maintain self-cannulation. Suggests practical techniques which can be incorporated into renal clinics and care plans.

Clinical, patient-related, and economic outcomes of home-based high-dose hemodialysis versus conventional in-center hemodialysis

Despite technological advances in renal replacement therapy, the preservation of health and quality of life for individuals on dialysis still remains a challenge. The high morbidity and mortality in dialysis warrant further research and insight into the clinical domains of the technique and practice of this therapy. In the last 20 years, the focus of development in the field of hemodialysis (HD) has centered around adequate removal of urea and other associated toxins. High-dose HD offers an opportunity to improve mortality, morbidity, and quality of life of patients with end-stage kidney disease. However, the uptake of this modality is low, and the risk associated with the therapy is not fully understood. Recent studies have highlighted the evidence base and improved our understanding of this technique of dialysis. This article provides a review of high-dose and home HD, its clinical impact on patient outcome, and the controversies that exist.

Comparative effectiveness of home dialysis therapies: a matched cohort study

Background

Home dialysis is being increasingly promoted among patients with end-stage renal disease, but the comparative effectiveness of home hemodialysis and peritoneal dialysis is unknown.

Objective

To determine whether patients receiving home daily hemodialysis have reduced mortality risk compared with matched patients receiving home peritoneal dialysis.

Design

This study is an observational, propensity-matched, new-user cohort study.

Setting

Linked electronic data were from the United States Renal Data System (USRDS) and a large dialysis provider’s database.

Patients

The patients were adults receiving in-center hemodialysis in the USA between 2004 and 2011 and registered in the USRDS.

Measurements

Baseline comorbidities, demographics, and outcomes for both groups were ascertained from the United States Renal Data System.

Methods

We identified 3142 consecutive adult patients initiating home daily hemodialysis (≥5 days/week for ≥1.5 h/day) and matched 2688 of them by propensity score to 2688 contemporaneous US patients initiating home peritoneal dialysis. We used Cox regression to compare all-cause mortality between groups.

Results

After matching, the two groups were well balanced on all baseline characteristics. Mean age was 51 years, 66 % were male, 72 % were white, and 29 % had diabetes. During 10,221 patient-years of follow-up, 1493/5336 patients died. There were significantly fewer deaths among patients receiving home daily hemodialysis than those receiving peritoneal dialysis (12.7 vs 16.7 deaths per 100 patient-years, respectively; hazard ratio (HR) 0.75; 95 % CI 0.68–0.82; p < 0.001). Similar results were noted with several different analytic methods and for all pre-specified subgroups.

Limitations

We cannot exclude residual confounding in this observational study.

Conclusions

Home daily hemodialysis was associated with lower mortality risk than home peritoneal dialysis.

Patient selection and training for home hemodialysis

Patient selection and training is arguably the most important step toward building a successful home hemodialysis (HD) program. We present a step-by-step account of home HD training to guide providers who are developing home HD programs. Although home HD training is an important step in allowing patients to undergo dialysis in the home, there is a surprising lack of systematic research in this field. Innovations and research in this area will be pivotal in further promoting a higher acceptance rate of home HD as the renal replacement therapy of choice.

The use of vascular access audit and infections in home hemodialysis

Vascular access-related infection is an important adverse event in home hemodialysis (HHD). We hypothesize that errors in self-cannulation or manipulation of dialysis vascular access are associated with increased incidence of access-related infection. We conducted a retrospective cohort study of all prevalent HHD patients at the University Health Network. All vascular access-related infections were recorded from 2006 to 2013. Errors in dialysis access were ascertained by nurse-administered vascular access checklist. Ninety-two patients had completed at least one vascular access audit. Median HHD vintage was 2.3 (0.9-5.0) years in patients with appropriate vascular access technique and 5.8 (1.5-9.4) years in patients with erroneous vascular access technique. The overall rate of infection between patients with and without appropriate vascular access technique was similar (0.27 and 0.28 infections per year, P = 0.166). Among patients who were identified with errors in dialysis access manipulation, patients with five or more errors were associated with higher rate of access-related infection (mean of 0.47 vs. 0.16 infection per patient-year, P < 0.001). The use of vascular access audit is a feasible strategy, which can identify errors in vascular access technique. Patients with a longer median HHD vintage are associated with higher risk of inappropriate vascular access technique. Patients with multiple errors in vascular access technique are associated with a higher risk of dialysis access-related infection. Prospective evaluation of the impact of vascular access audit on adverse vascular access events is warranted.

The Association Between Conversion to In-centre Nocturnal Hemodialysis and Left Ventricular Mass Regression in Patients With End-Stage Renal Disease

BACKGROUND

In-centre nocturnal hemodialysis (INHD, 7-8 hours/session, 3 times/week) is an increasingly utilized form of dialysis intensification, though data on the cardiovascular benefits of this modality are limited.

METHODS

In this prospective cohort study, we enrolled 67 prevalent conventional hemodialysis (CHD, 4 hours/session, 3 times/week) recipients at 2 medical centres in Canada, of whom 37 converted to INHD and 30 remained on CHD. The primary outcome was the change in left ventricular mass (LVM) after 1 year as assessed by cardiac magnetic resonance imaging. Secondary outcomes included changes in serum phosphate concentration, phosphate binder burden, haemoglobin, erythropoiesis stimulating agent usage, and blood pressure.

RESULTS

Conversion to INHD was associated with a 14.2 (95% confidence interval [CI] 1.2-27.2) g reduction in LVM as compared with continuation on CHD. This result was maintained after adjustment for baseline imbalances between the groups and in ancillary analyses. There was a trend toward a larger drop in systolic blood pressure (9.8 [95% CI, -1.4-20.9] mm Hg) among INHD recipients with a significant reduction in the number of prescribed antihypertensive agents (0.7 [95% CI, 0.3-1.1] agents). Serum phosphate declined by 0.40 (95% CI, 0.16-0.63) mmol/L among INHD recipients without any difference in calcium-based phosphate binder requirements, as compared with those who remained on CHD.

CONCLUSIONS

Compared with continuation of CHD, conversion to INHD was associated with significant LVM regression and reduction in serum phosphate concentration at 1 year.

Optimizing outcomes in the elderly with end-stage renal disease--live long and prosper

BACKGROUND

The elderly form an expanding proportion of patients with chronic kidney disease and end-stage renal disease worldwide. The increased physiological frailty and functional morbidity associated with the aging process pose unique challenges when planning optimal management of an older patient needing renal replacement therapy (RRT).

AIMS

This position paper discusses current evidence regarding the optimal management of end-stage renal disease in the elderly with an emphasis on hemodialysis since it is the most common modality used in older patients. Further research is needed to define relevant patient-reported outcome measures for end-stage renal disease including functional assessments and psychological impacts of various forms of RRT. For those older patients who have opted for dialysis treatment, it is important to study the strategies that encourage greater uptake of home-based dialysis therapies and optimal vascular access.

CONCLUSIONS

The management of advanced chronic kidney disease in the elderly can be challenging but also extremely rewarding. The key issue is adopting a patient-focused and individualized approach that seeks to achieve the best outcomes based on a comprehensive holistic assessment of what is important to the patient.

Self-cannulation for haemodialysis: patient attributes, clinical correlates and self-cannulation predilection models

BACKGROUND AND OBJECTIVES

With emerging evidence in support of home haemodialysis (HHD), patient factors which determine uptake of the modality need to be better understood. Self-cannulation (SC) is a major step towards enabling self-care 'in-centre' and at home and remains the foremost barrier to its uptake. Human factors governing this aspect of HD practice are poorly understood. The aim of this study is to better understand self-cannulation preferences and factors which define them in end stage renal disease (ESRD).

DESIGN

In this multicentre study, 508 of 535 patients from predialysis (Group A: n = 222), in-centre (Group B: n = 213), and home HD (Group C: n = 100) responded to a questionnaire with 3 self-cannulation questions. Simultaneously, data on clinical, cognitive and psychosocial variables were ascertained. The primary outcome measure was 'perceived ability to self-cannulate AV access'. Predictive models were developed using logistic regression analysis.

RESULTS

36.6% of predialysis patients (A) and 29.1% of the 'in-centre' haemodialysis patients (B) felt able to consider SC for HD. Technical-skills related apprehension was highest in Group B (14.4%) patients. Response to routine venepuncture and the types of SC concerns were significant predictors of perceived ability to self-cannulate. There was no significant difference in concern for pain across the groups. In multivariable regression analysis, age, education level, 3 MS score, hypoalbuminemia in Groups B & C and additionally, attitude to routine phlebotomy and the nature of specific concern for self-cannulation in Groups A, B and C, are significant predictors of SC preference. The unadjusted c-statistics of models 1 (derived from Group A and validated on A) and 2 (derived from B+C and validated on B), are 0.76(95% CI 0.69, 0.83) and 0.80 (95% CI 0.74, 0.87) respectively.

CONCLUSIONS

There is high prevalence of perceived ability to self-cannulate. Modifiable SC concerns exist in ESRD. The use of predictive models to objectively define and target education and training strategies could potentially impact on HD self-management and future uptake of home HD.

The home hemodialysis hub: physical infrastructure and integrated governance structure

An effective home hemodialysis program critically depends on adequate hub facilities and support functions and on transparent and accountable organizational processes. The likelihood of optimal service delivery and patient care will be enhanced by fit-for-purpose facilities and implementation of a well-considered governance structure. In this article, we describe the required accommodation and infrastructure for a home hemodialysis program and a generic organizational structure that will support both patient-facing clinical activities and business processes.

Travel distance and home dialysis rates in the United States

INTRODUCTION

Rural residence is associated with increased peritoneal dialysis (PD) utilization. The influence of travel distance on rates of home dialysis utilization has not been examined in the United States. The purpose of this study was to determine whether travel distances to the closest home and in-center hemodialysis (IHD) facilities are a barrier to home dialysis. ♢

METHODS

This was a retrospective cohort study of patients aged ≥ 18 years initiating dialysis between 2005 and 2011. Unadjusted PD and home hemodialysis (HHD) rates were compared by travel distances to both the closest home dialysis and closest IHD facilities. Adjusted PD and HHD utilization rates were examined using multivariable logistic regression models. ♢

RESULTS

There were 98,608 patients in the adjusted analyses. 55.5% of the dialysis facilities offered home dialysis. IHD, PD and HHD patients traveled median distances of 5.4, 3.5 and 6.6 miles respectively to their initial dialysis facilities. Unadjusted analyses showed an increase in PD rates and decrease in HHD rates with increased travel distances. Adjusted odds of PD and HHD were 1.6 and 1.2 respectively for a ten mile increase in distance to the closest home dialysis facility, while for distances to the closest IHD facility the odds ratios for both PD and HHD were 0.7 (all p < 0.01). ♢

CONCLUSIONS

In metropolitan areas, PD and HHD generally increased with increased travel distance to the closest home dialysis facility and decreased with greater distance to an IHD facility. Examination of travel distances to PD and HHD facilities separately may provide further insight on specific barriers to these modalities which can serve as targets for future studies examining expansion of home dialysis utilization.
