Prescribing the dialysis dose and treatment frequency in home haemodialysis.

BACKGROUND: There is growing interest in home haemodialysis (HHD) performed with low-flow dialysate devices and variable treatment schedules. The target standard Kt/V (stdKt/V) should be 2.3 volumes/week, according to KDOQI guidelines (2015). The current formula for stdKt/V does not help prescribe the dialysis dose (eKt/V) and treatment frequency (TF). The aim of this study was to obtain a formula for stdKt/V that is able to define the minimum required values of eKt/V and TF to achieve the targeted stdKtV. METHODS: Thirty-eight prevalent patients on HHD were enrolled. A total of 231 clinical datasets were available for urea modelling using the Solute-Solver software (SS), recommended by KDOQI guidelines. A new formula (stdKt/V = a + b × Kru + c × eKt/V) was obtained from multivariable regression analysis of stdKt/V vs eKt/V and residual kidney urea clearance (Kru). The values of coefficients a, b and c depend on the treatment schedules and the day of the week of blood sampling for the kinetic study (labdayofwk) and then vary for each of their foreseen 62 combinations. For practical purposes, we used only seven combinations, assuming Monday as a labdayofwk for each of the most common schedules of the 7 days of the week. RESULTS: The stdKt/V values obtained with SS were compared with the paired ones obtained with the formula. The mean ± standard deviation stdKt/V values obtained with SS and the formula were 3.043 ± 0.530 and 2.990 ± 0.553, respectively, with 95% confidence interval +0.15 to -0.26. A 'prescription graph' was built using the formula to draw lines expressing the relationship between Kru and required eKt/V for each TF. Using this graph, TF could have been reduced from the delivered 5.8 ± 0.8 to 4.8 ± 0.8 weekly sessions. CONCLUSIONS: The new formula for stdKtV is reliable and can support clinicians to prescribe the dialysis dose and TF in patients undergoing HHD.

Barriers to Home Haemodialysis.

INTRODUCTION: Significant variation exists in the prevalence of home haemodialysis (HHD) among UK renal centres. Our centre has a HHD prevalence of 2%, and we aimed to study how many patients who chose HHD as their preferred mode of renal replacement therapy (RRT) went on to receive this treatment and the barriers to starting this treatment. METHODS: A retrospective single-centre analysis of electronic medical records for all patients who chose HHD at the time of RRT education was performed, and data were collected on patient demographics, comorbidity, frailty, RRT events, and barriers to HHD. RESULTS: 116 patients chose HHD as their preferred mode of RRT between 2006 and 2018. Of these patients, 93 required RRT, but only 28 patients ever received HHD. No statistical difference was identified between those patients who only received unit haemodialysis (UHD) and those who went onto receive HHD with respect to age, gender, comorbidity, frailty, and socioeconomic deprivation. Patient choice, change in clinical condition, transplantation, home environment, vascular access problems, and training delays were identified as reasons patients did not start HHD. No documented reason could be found in 9 patients with a breakdown of communication between clinics and peripheral dialysis units attributed as a significant contributor in some of these patients. Of the 26 patients who started HHD after UHD, 19 did so within 1 year of starting UHD. CONCLUSION: Most patients who choose HHD do not receive HHD. Many patients never start HHD because of potentially reversible barriers including inadequate communication among clinicians about patient choices, patients changing their minds once in a dialysis unit, and inadequate timely training support.

Trends in home dialysis use differ among age categories in past two decades: A Dutch registry study.

BACKGROUND: Although the number of patients with end-stage kidney disease is growing, the number of patients who perform dialysis at home has decreased during the past two decades. The aim of this study was to explore time trends in the use of home dialysis in the Netherlands. METHODS: Dialysis episodes of patients who started dialysis treatment were studied using Dutch registry data (RENINE). The uptake of home dialysis between 1997 through 2016 was evaluated in time periods of 5 years. Home dialysis was defined as start with peritoneal dialysis or home haemodialysis, or transfer to either within 2 years of dialysis initiation. All analyses were stratified for age categories. Mixed model logistic regression analysis was used to adjust for clustering at patient level. RESULTS: A total of 33 340 dialysis episodes in 31 569 patients were evaluated. Mean age at dialysis initiation increased from 62.5 ± 14.0 to 65.5 ± 14.5 years in in-centre haemodialysis patients, whereas it increased from 51.9 ± 15.1 to 62.5 ± 14.6 years in home dialysis patients. In patients <65 years, the uptake of home dialysis was significantly lower during each 5-year period compared with the previous period, whereas kidney transplantation occurred more often. In patients ≥65 years, the incidence of home dialysis remained constant, whereas mortality decreased. CONCLUSIONS: In patients <65 years, the overall use of home dialysis declined consistently over the past 20 years. The age of home dialysis patients increased more rapidly than that of in-centre dialysis patients. These developments have a significant impact on the organization of home dialysis.

Similar survival on home haemodialysis and automated peritoneal dialysis: an inception cohort study.

BACKGROUND: Several studies have shown superior survival of patients on home haemodialysis (HD) compared with peritoneal dialysis (PD), but patients on automated PD (APD) and continuous ambulatory PD (CAPD) have not been considered separately. As APD allows larger fluid volumes and may be more efficient than CAPD, we primarily compared patient survival between APD and home HD. METHODS: All adult patients who started kidney replacement therapy (KRT) between 2004 and 2017 in the district of Helsinki-Uusimaa in Finland and who were on one of the home dialysis modalities at 90 days from starting KRT were included. We used intention-to-treat analysis. Survival of home HD, APD and CAPD patients was studied using Kaplan-Meier curves and Cox regression with adjustment for propensity scores that were based on extensive data on possible confounding factors. RESULTS: The probability of surviving 5 years was 90% for home HD, 88% for APD and 56% for CAPD patients. After adjustment for propensity scores, the hazard ratio of death was 1.1 [95% confidence interval (CI) 0.52-2.4] for APD and 1.6 (95% CI 0.74-3.6) for CAPD compared with home HD. Censoring at the time of kidney transplantation (KTx) or at transfer to in-centre HD did not change the results. Characteristics of home HD and APD patients at the start of dialysis were similar, whereas patients on CAPD had higher median age and more comorbidities and received KTx less frequently. CONCLUSIONS: Home HD and APD patients had comparable characteristics and their survival appeared similar.

A Quality Improvement Process to Increase and Sustain a Peritoneal Dialysis Programme in the United Kingdom.

INTRODUCTION: Peritoneal dialysis (PD) remains underutilised in the West. The proportion of patients in the UK starting renal replacement therapy (RRT) with PD fell from 7.2% in 2011 to 6.0% in 2016. At our centre, 8.4% of dialysis patients received PD in April 2014. Evidence suggests that home dialysis improves patient clinical outcomes; therefore, a target was agreed to achieve 25% of dialysis patients receiving PD by 2018. METHODS: A rapid improvement process was introduced, as a quality improvement tool, to increase and sustain the PD programme. With multidisciplinary team support for PD growth, a nephrologist was trained to insert PD catheters. Nurses were trained to provide patients with balanced pre-dialysis information and discuss alternative dialysis modalities with haemodialysis (HD) patients. The "Acceptance, Choice and Empowerment" project raised awareness of home therapy choices, using a peer educator model specifically for ethnic minority patients. Lean methodologies were used to ensure continuous quality improvement. RESULTS: PD uptake increased from 37 to 84 patients, giving a PD penetration increase from 8.4% to 19.1% between April 2014 and March 2018. Catheter insertions increased from 94 at the end of QI Period 1 to 185 at the end of QI Period 2, representing a 97% increase, with the medical/surgical split remaining stable. Peritonitis rates remained stable, and PD drop off to HD reduced from 52% to 41% during the same period. CONCLUSIONS: By implementing a rapid improvement process and embedding a quality improvement programme, the number of incidents and prevalent PD patients increased and was sustained.

Anxiety and psychosocial impact during coronavirus disease 2019 in home dialysis patients.

The severe acute respiratory syndrome coronavirus (SARS-Cov-2) resulting in the coronavirus disease 2019 (COVID-19) is documented to have a negative psychosocial impact on patients. Home dialysis patients may be at risk of additional isolating factors affecting their mental health. The aim of this study is to describe levels of anxiety and quality of life during the COVID-19 pandemic among home dialysis patients. This is a single-centre survey of home dialysis patients in Toronto, Ontario. Surveys were sent to 98 home haemodialysis and 43 peritoneal dialysis patients. Validated instruments (Haemodialysis and Peritoneal Dialysis Treatment Satisfaction Questionnaire, Generalized Anxiety Disorder 7 Item [GAD7] Scale, Patient Health Questionnaire [PHQ-9], Illness Intrusiveness Ratings Scale, Family APGAR Questionnaire and The Self Perceived Burden Scale) assessing well-being were used. Forty of the 141 patients surveyed, participated in September 2020. The mean age was 53.1 ± 12.1 years, with 60% male, and 85% home haemodialysis, 80% of patients rated their satisfaction with dialysis at 8/10 or greater, 82% of respondents reported either "not at all" or "for several days" indicating frequency of anxiety and depressive symptoms, 79% said their illness minimally or moderately impacted their life, 76% of respondents were almost always satisfied with interactions with family members, 91% were never or sometimes worried about caregiver burden. Among our respondents, there was no indication of a negative psychosocial impact from the pandemic, despite the increased social isolation. Our data further supports the use of home dialysis as the optimal form of dialysis.

Risk assessment of failure during transitioning from in-centre to home haemodialysis.

BACKGROUND: Introducing a de-novo home haemodialysis (HHD) program often raises safety concerns as errors could potentially lead to serious adverse events. Despite the complexity of performing haemodialysis at home without the supervision of healthcare staff, HHD has a good safety record. We aim to pre-emptively identify and reduce the risks to our new HHD program by risk assessment and using failure mode and effects analysis (FMEA) to identify potential defects in the design and planning of HHD. METHODS: We performed a general risk assessment of failure during transitioning from in-centre to HHD with a failure mode and effects analysis focused on the highest areas of failure. We collaborated with key team members from a well-established HHD program and one HHD patient. Risk assessment was conducted separately and then through video conference meetings for joint deliberation. We listed all key processes, sub-processes, step and then identified failure mode by scoring based on risk priority numbers. Solutions were then designed to eliminate and mitigate risk. RESULTS: Transitioning to HHD was found to have the highest risk of failure with 3 main processes and 34 steps. We identified a total of 59 areas with potential failures. The median and mean risk priority number (RPN) scores from failure mode effect analysis were 5 and 38, with the highest RPN related to vascular access at 256. As many failure modes with high RPN scores were related to vascular access, we focussed on FMEA by identifying the risk mitigation strategies and possible solutions in all 9 areas in access-related medical emergencies in a bundled- approach. We discussed, the risk reduction areas of setting up HHD and how to address incidents that occurred and those not preventable. CONCLUSIONS: We developed a safety framework for a de-novo HHD program by performing FMEA in high-risk areas. The involvement of two teams with different clinical experience for HHD allowed us to successfully pre-emptively identify risks and develop solutions.

Design of therapeutic education workshops for home haemodialysis in a patient-centered chronic kidney diseases research: a qualitative study.

RATIONALE & OBJECTIVE: A quarter of patients do not receive any information on the modalities of renal remplacement therapy (RRT) before its initiation. In our facility, we provide therapeutic education workshops for all RRT except for home hemodialysis (HHD). The objectives of this study were to identify and describe the needs of CKD patients and caregivers for RRT with HHD and design therapeutic education workshops. SETTING & PARTICIPANTS: Two sequential methods of qualitative data collection were conducted. Interviews with patients treated with HHD and doctors specialized in HHD were performed to define the interview guide followed by semi-structured interviews with the help of HHD patients from our center. ANALYTIC APPROACH: Thematic analysis was conducted and were rooted in the principles of qualitative analysis for social scientists. Data were analyzed by two investigators. Transcribed interviews were entered into RQDA 3.6.1 software for data organization and coding purposes (Version 3.6.1). RESULTS: In total, five interviews were performed. We identified six themes related to the barriers, facilitators, and potential solutions to home dialysis therapy: (1) HHD allows autonomy and freedom with constraints, (2) safety of the care environment, (3) the caregiver and family environment, (4) patient's experience and experiential knowledge, (5) self-care experience and impact on life, and (6) factors that impact the choice of treatment with HHD. We designed therapeutic education workshops in a group of patients and caregivers. CONCLUSIONS: Our study confirmed previous results obtained in literature on the major barriers, facilitators, and potential solutions to HHD including the impact of HHD on the caregiver, the experiences of patients already treated with HHD, and the role of nurses and nephrologists in informing and educating patients. A program to develop patient-to-patient peer mentorship allowing patients to discuss their dialysis experience may be relevant.

Home and facility haemodialysis patients: a comparison of outcomes in a matched cohort.

BACKGROUND: Home haemodialysis (HHD) is utilized significantly less often than facility HD globally with few exceptions, despite being associated with improved survival and better quality of life. Previously HHD was exclusively offered to younger patients with a few comorbidities. However, with the increasing burden of end-stage kidney disease (ESKD) alongside an ageing population, increasing numbers of older patients are being treated with HHD. This study aims to re-evaluate survival and related outcomes in the context of this epidemiological shift. METHODS: A matched cohort design was used to compare all-cause mortality, transplantation, average biochemical values and graft survival 6 months post-transplant between HHD and facility HD patients. A total of 181 HHD patients from a major hospital network were included with 413 facility HD patients from the Australia and New Zealand Dialysis and Transplant Registry matched by age, gender and cause of ESKD. Survival analysis and competing risks analysis (for transplantation) were performed. RESULTS: After adjusting for body mass index, smoking status, racial group and comorbidities, HHD was associated with a significantly reduced risk of death compared with facility HD patients [hazard ratio 0.47 (95% confidence interval 0.30-0.74)]. Transplantation rates were comparable, with high rates of graft survival at 6 months in both groups. Haemoglobin, calcium and parathyroid hormone levels did not vary significantly. However, HHD patients had significantly lower phosphate levels. CONCLUSIONS: In this study, improved survival outcomes were observed in patients on home compared with facility dialysis, with comparable rates of transplantation, graft survival and biochemical control.

Managing heart failure in dialysis patients.

The heart and the kidney are intimately connected. They communicate in a bidirectional manner through a variety of pathways, forming an interdependent relationship. Recognition of this co-dependency is crucial in managing patients with cardiorenal syndrome, as we begin to realise the inevitability of disease progression to both organs; and an approach that focuses treatment on one organ may result in worsening outcome on the other organ. When faced with patients with deteriorating cardiac disease, nephrologists tend to focus on stabilisation of cardiac function and accept the heart disease to be unmodifiable. Likewise, cardiac patients with persistent kidney failure are presented with a poor renal prognosis and prepared for kidney transplantation. Adopting a cardio-protective approach in combination with dialysis optimisation raises hope for a more positive outcome with evidence of cardiac and renal recovery in some patients.

The use of virtual physician mentoring to enhance home dialysis knowledge and uptake.

Home dialysis therapies are flexible kidney replacement strategies with documented clinical benefits. While the incidence of end-stage kidney disease continues to increase globally, the use of home dialysis remains low in most developed countries. Multiple barriers to providing home dialysis have been noted in the published literature. Among known challenges, gaps in clinician knowledge are potentially addressable with a focused education strategy. Recent national surveys in the United States and Australia have highlighted the need for enhanced home dialysis knowledge especially among nephrologists who have recently completed training. Traditional in-person continuing professional educational programmes have had modest success in promoting home dialysis and are limited by scale and the present global COVID-19 pandemic. We hypothesize that the use of a 'Hub and Spoke' model of virtual home dialysis mentorship for nephrologists based on project ECHO would support home dialysis growth. We review the home dialysis literature, known educational gaps and plausible educational interventions to address current limitations in physician education.

Lifetime cost-effectiveness analysis of first-line dialysis modalities for patients with end-stage renal disease under peritoneal dialysis first policy.

BACKGROUND: This study aimed to determine the lifetime cost-effectiveness of first-line dialysis modalities for end-stage renal disease (ESRD) patients under the "Peritoneal Dialysis First" policy. METHODS: Lifetime cost-effectiveness analyses from both healthcare provider and societal perspectives were performed using Markov modelling by simulating at age 60. Empirical data on costs and health utility scores collected from our studies were combined with published data on health state transitions and survival data to estimate the lifetime cost, quality-adjusted life-years (QALYs) and cost-effectiveness of three competing dialysis modalities: peritoneal dialysis (PD), hospital-based haemodialysis (HD) and nocturnal home HD. RESULTS: For cost-effectiveness analysis over a lifetime horizon from the perspective of healthcare provider, hospital-based HD group (lifetime cost USD$142,389; 6.58 QALYs) was dominated by the PD group (USD$76,915; 7.13 QALYs). Home-based HD had the highest effectiveness (8.37 QALYs) but with higher cost (USD$97,917) than the PD group. The incremental cost-effectiveness ratio (ICER) was USD$16,934 per QALY gained for home-based HD over PD. From the societal perspective, the results were similar and the ICER was USD$1195 per QALY gained for home-based HD over PD. Both ICERs fell within the acceptable thresholds. Changes in model parameters via sensitivity analyses had a minimal impact on ICER values. CONCLUSIONS: This study assessed the cost-effectiveness of dialysis modalities and service delivery models for ESRD patients under "Peritoneal Dialysis First" policy. For both healthcare provider and societal perspectives, PD as first-line dialysis modality was cost-saving relative to hospital-based HD, supporting the existing PD First or favoured policy. When compared with PD, Nocturnal home Home-based HD was considered a cost-effective first-line dialysis modality for ESRD patients.

Comparison of physical activity and quality of life in home haemodialysis (HHD) patients versus conventional in-centre haemodialysis (ICHD) patients: the observational, longitudinal, prospective, international, multicentric SeCoIA study protocol.

BACKGROUND: Home haemodialysis (HHD), has shown improved clinical outcomes, as well as a better quality of life, compared to conventional in-centre haemodialysis (ICHD) but still has a global low prevalence among end-stage renal disease patients. Haemodialysis (HD) patients tend to be sedentary but only few studies, mainly in North American ICHD patients, have evaluated the level of activity in HD patients. METHODS: SeCoIA is an observational, longitudinal, prospective, international, multicentric, study, conducted in metropolitan France and Belgium. The main objective of the study is to quantify the physical activity measured by the total daily number of steps, in HHD patients compared to ICHD patients. The SeCoIA study will include 80 HHD patients and 80 ICHD patients,. Secondary objectives will be to characterize the HHD population and to confirm HHD efficiency on clinical parameters, as well as quality of life (QoL), in current practice. Physical activity will be measured by a 3-axis accelerometer. Accelerometers have been shown to provide accurate information, on both physical activity and sedentary behaviour. Patients will be instructed to wear the device and complete a patient diary 7 consecutive days after inclusion and the first week of each month for 12 months. Decision to undergo HDD or ICHD is independent of the study and follow-up frequency remains at the discretion of the physician/centre. QoL and quality of sleep will be respectively assessed by the Kidney Disease Quality of Life 1.2 (KDQOL™) and the Pittsburg Sleep Quality index (PSQI) questionnaires at inclusion, 6- and 12-month visits. Patients presenting a restless leg syndrome (RLS) will also complete the International Restless Legs Syndrome rating scale (IRLS) questionnaire. DISCUSSION: The SeCoIA study will be the first large cohort study (160 patients) evaluating physical activity, objectively measured with a 3-axis accelerometer, in HHD versus ICHD patients. The present study will also include a comparison of QoL with a focus on RLS between HHD and ICHD. It is anticipated that HHD patients will have an improved physical activity and QoL which should encourage physicians to further promote HHD. TRIAL REGISTRATION: Clinical trial NCT03737578 study registered on November 9, 2018 (Retrospectively registered).

Direct and indirect costs of end-stage renal disease patients in the first and second years after initiation of nocturnal home haemodialysis, hospital haemodialysis and peritoneal dialysis.

PURPOSE: To estimate the direct and indirect costs of end-stage renal disease (ESRD) patients in the first and second years of initiating peritoneal dialysis (PD), hospital-based haemodialysis (HD) and nocturnal home HD. METHODS: A cost analysis was performed to estimate the annual costs of PD, hospital-based HD and nocturnal home HD for ESRD patients from both the health service provider's and societal perspectives. Empirical data on healthcare resource use, patients' out-of-pocket costs, time spent on transportation and dialysis by ESRD patients and time spent by caregivers were analysed. All costs were expressed in Hong Kong year 2017 dollars. RESULTS: Analysis was based on 402 ESRD patients on maintenance dialysis (PD: 189; hospital-based HD: 170; and nocturnal home HD: 43). From the perspective of the healthcare provider, hospital-based HD had the highest total annual direct medical costs in the initial year (mean ± SD) (hospital-based HD = $400 057 ± 62 822; PD = $118 467 ± 15 559; nocturnal home HD = $223 358 ± 18 055; P < 0.001) and second year (hospital-based HD = $360 924 ± 63 014; PD = $80 796 ± 15 820; nocturnal home HD = $87 028 ± 9059; P < 0.001). From the societal perspective, hospital-based HD had the highest total annual costs in the initial year (hospital-based HD = $452 151 ± 73 327; PD = $189 191 ± 61 735; nocturnal home HD = $242 038 ± 28 281; P < 0.001) and second year (hospital-based HD = $413 017 ± 73 501; PD = $151 520 ± 60 353; nocturnal home HD = $105 708 ± 23 853; P < 0.001). CONCLUSIONS: This study quantified the economic burden of ESRD patients, and assessed the annual healthcare and societal costs in the initial and second years of PD, hospital-based HD and nocturnal home HD in Hong Kong. From both perspectives, PD is cost-saving relative to hospital-based HD and nocturnal home HD, except that nocturnal home HD has the lowest cost in the second year of treatment from the societal perspective. Results from this cost analysis facilitate economic evaluation in Hong Kong for health services and management targeted at ESRD patients.

Changing ethnic and clinical trends and factors associated with successful home haemodialysis at Auckland District Health Board.

BACKGROUND: The health and diversity of the population in New Zealand (NZ) is changing under the influence of many socio-economic factors. This may have shifted the landscape of home haemodialysis (HHD). AIMS: To examine the demographic and clinical changes, determinants of HHD training and technique outcome and mortality between 2008 and 2015 at Auckland District Health Board, NZ. METHODS: We compared three incident cohorts of HHD patients between 2008 and 2015. Relevant factors, including demographic and clinical characteristics, training failure, technique failure and mortality were recorded. Factors associated with training and technique failure were examined by multivariate logistic regression. RESULTS: Of 152 patients, 133 completed training, 13 (10%) experienced technique failure and 15 (11%) died. Significant changes in ethnicity (increased: Maori 1.7-fold, Asian 1.7-fold and Pasifika 1.4-fold; decreased: NZ European 2.7-fold, P = 0.001), and major comorbidities, ≥2 major comorbidities (1.8-fold increase, P = 0.03), diabetes (2.1-fold increase, P = 0.013) and heart failure (P = 0.04) were seen. HHD as first renal replacement therapy modality increased 15-fold (P = 0.0001) and training time increased by 4.5 weeks (P = 0.004). Death and technique failure were unchanged over time. Shorter training time, employment and lower C-reactive protein were associated with 'Successful HHD'. 'Unsuccessful HHD' patient characteristics differed by ethnicity. CONCLUSIONS: The HHD population has become more representative of the NZ population, but significantly more comorbid over time. Patient training time has increased, but mortality and technique failure remain stable. 'Successful HHD' is predicted by social and clinical factors, and 'unsuccessful HHD' may have different mechanisms in different patient groups.

Health-related quality of life and health utility of Chinese patients undergoing nocturnal home haemodialysis in comparison with other modes of dialysis.

BACKGROUND: To compare the health-related quality of life (HRQOL) and health utility of Chinese patients with end-stage renal disease (ESRD) undergoing nocturnal home haemodialysis (Home HD) against those patients undergoing other modes of dialysis. METHODS: Chinese ESRD patients undergoing Home HD were recruited in renal specialist outpatient clinics at three public hospitals in Hong Kong. SF-12 Health Survey (SF-12) was used to measure HRQOL and generate the SF-6D heath utility score. Mean scores of SF-12 domains, physical and mental component summary and SF-6D health utility of 41 patients undergoing Home HD were compared with available scores of patients receiving other forms of dialysis, namely, peritoneal dialysis (PD) (n = 103), hospital in-centre HD (n = 135) or community in-centre HD (n = 118). Adjusted linear regression models were used to examine the impact of mode of dialysis on the HRQOL and health utility scores, accounting for the sociodemographic and clinical characteristics. RESULTS: ESRD patients undergoing PD and community in-centre HD had better health utility, physical and mental component summary scores than the hospital in-centre HD. Adjusted analysis showed that hospital in-centre HD reported worse physical component summary and health utility scores when compared with PD and community in-centre HD. CONCLUSION: HRQOL and health utility scores of patients undergoing Home HD were similar to those undergoing PD and community in-centre HD. Better physical aspects of HRQOL and health utility was observed in PD and community-based HD than hospital in-centre HD, providing evidence for the increase in capacity of non-hospital-based HD, which provided flexibility as well as patient centredness and empowerment in Hong Kong.

Dutch nOcturnal and hoME dialysis Study To Improve Clinical Outcomes (DOMESTICO): rationale and design.

BACKGROUND: More than 6200 End Stage Renal Disease patients in the Netherlands are dependent on dialysis, either performed at home or in a dialysis centre. Visiting a dialysis centre three times a week is considered a large burden by many patients. However, recent data regarding the effects of dialysis at home on quality of life, clinical outcomes, and costs compared with in-centre haemodialysis are lacking. METHODS: The Dutch nOcturnal and hoME dialysis Study To Improve Clinical Outcomes (DOMESTICO) is a nationwide, prospective, observational cohort study that will include adult patients starting with a form of dialysis. Health-related quality of life, as the primary outcome, clinical outcomes and costs, as secondary outcomes, will be measured every 3-6 months in patients on home dialysis, and compared with a control group consisting of in-centre haemodialysis patients. During a 3-year period 800 home dialysis patients (600 peritoneal dialysis and 200 home haemodialysis patients) and a comparison group of 800 in-centre haemodialysis patients will be included from 53 Dutch dialysis centres (covering 96% of Dutch centres) and 1 Belgian dialysis centre (covering 4% of Flemish centres). DISCUSSION: DOMESTICO will prospectively investigate the effect of home dialysis therapies on health-related quality of life, clinical outcomes and costs, in comparison with in-centre haemodialysis. The findings of this study are expected to ameliorate the shared decision-making process and give more guidance to healthcare professionals, in particular to assess which type of patients may benefit most from home dialysis. TRIAL REGISTRATION: The DOMESTICO study is registered with the National Trial Register on (number: NL6519 , date of registration: 22 August 2017) and the Central Committee on Research Involving Human Subjects (CCMO) (number: NL63277.029.17).

Clinical study on low-molecular weight heparin infusion as anticoagulation for nocturnal home haemodialysis.

AIM: This study was conducted to evaluate low-molecular weight heparin (LMWH) as anticoagulation for nocturnal home haemodialysis (NHHD). While its longer half-life may cause drug accumulation in frequent dialysis, the essential need of a supplementary intra-dialytic bolus for the sleeping patients also renders LMWH's use impractical. METHODS: The recruited patients, who were on alternate-day 8 h haemodialysis, were randomized to receive either nadroparin or unfractionated heparin (UFH) for a week. They underwent crossover to receive the alternate anticoagulant in the next week. A nadroparin infusion regimen was adopted to enhance its practicability, which consisted of a loading dose of 35 IU/kg and a continuous infusion of 10 IU/kg per hour for 6 h. RESULTS: A total of 12 NHHD patients were recruited. With nadroparin infusion, the mean anti-Xa levels at the 2nd , 4th , 6th and 8th hours of dialysis were 0.46 ± 0.11, 0.55 ± 0.14, 0.61 ± 0.15 and 0.45 ± 0.15 IU/mL respectively. Comparing to UFH, which offered satisfactory anticoagulation according to the activated partial thromboplastin time, nadroparin-treated dialysis achieved similar thrombus scores and dialyser urea/creatinine clearances at the end of haemodialysis. During the post-dialysis period, one patient demonstrated residual LMWH effect (anti-Xa level 0.09 IU/mL) on the next day, whereas none had detectable anti-Xa activities 2 days afterwards upon next dialysis. CONCLUSIONS: Low-molecular weight heparin infusion is practical and effective as anticoagulation for NHHD. It can be safely used in an alternate-day haemodialysis schedule. A close monitoring for LMWH accumulation is recommended if long dialysis is performed daily.

Patient experiences of training and transition to home haemodialysis: A mixed-methods study.

AIM: This study aims to describe patients' perspectives on the transition to home haemodialysis. METHODS: Up to three sequential semi-structured interviews were conducted with 20 patients during the transition to home haemodialysis at an Australian renal unit. Transcripts were analysed thematically. Participants completed a satisfaction questionnaire after commencing home haemodialysis. RESULTS: We identified six themes: persevering despite trepidations (diminishing intimidation of machinery, acquiescing to fatal risks, reconciling fears of cannulation, dispelling concerns of neglect and tolerating necessary concessions); optimizing the learning pathway (practising problem solving, learning from mistakes, grasping technical complexity, minimizing cognitive overload and progressing at own pace); developing confidence (believing in own abilities, adapting to independence, depending on caregiver partnership and faith in crisis support); interrupted transition momentum (lacking individual attention, language barriers, installation delays, interfering illness and complications and acclimatizing to new conditions); noticing immediate gains (reclaiming lifestyle normality, satisfying self-sufficiency, personalizing treatment regime and thriving in a positive environment); and depleting resources and energy (exhaustion with gruelling routine, confronting medicalization of the home, draining financial reserves and imposing family burden). Fewer than 30% of respondents indicated low satisfaction with staff availability domains, staff interpersonal domains or technical domains. CONCLUSION: Home haemodialysis training fosters confidence in patients; however, many patients experience stress because of medical isolation, treatment responsibilities, family impositions and financial difficulties. Addressing patient's on-going psychosocial concerns may alleviate burdens on patients and their families during the transition to home haemodialysis.

Patient and caregiver values, beliefs and experiences when considering home dialysis as a treatment option: a semi-structured interview study.

BACKGROUND: Home dialysis can offer improved quality of life and economic benefits compared with facility dialysis. Yet the uptake of home dialysis remains low around the world, which may be partly due to patients' lack of knowledge and barriers to shared and informed decision-making. We aimed to describe patient and caregiver values, beliefs and experiences when considering home dialysis, to inform strategies to align policy and practice with patients' needs. METHODS: Semi-structured interviews with adult patients with chronic kidney disease Stage 4-5D (on dialysis <1 year) and their caregivers, recruited from three nephrology centres in New Zealand. Transcripts were analysed thematically. RESULTS: In total, 43 patients [pre-dialysis (n = 18), peritoneal dialysis (n = 13), home haemodialysis (n = 4) and facility haemodialysis (n = 9)] and 9 caregivers participated. We identified five themes related to home dialysis: lacking decisional power (complexity of information, limited exposure to home dialysis, feeling disempowered, deprived of choice, pressure to choose), sustaining relationships (maintaining cultural involvement, family influence, trusting clinicians, minimizing social isolation), reducing lifestyle disruption (sustaining employment, avoiding relocation, considering additional expenses, seeking flexible schedules, creating free time), gaining confidence in choice (guarantee of safety, depending on professional certainty, reassurance from peers, overcoming fears) and maximizing survival. CONCLUSIONS: To engage and empower patients and caregivers to consider home dialysis, a stronger emphasis on the development of patient-focused educational programmes and resources is suggested. Pre-dialysis and home dialysis programmes that address health literacy and focus on cultural and social values may reduce fears and build confidence around decisions to undertake home dialysis. Financial burdens may be minimized through provision of reimbursement programmes, employment support and additional assistance for patients, particularly those residing in remote areas.
