Needs and Considerations for Standardization of Kidney Disease Education in Patients with Advanced CKD

Kidney health advocacy organizations and leaders in the nephrology community have repeatedly emphasized the need to increase home dialysis utilization in the United States. Limited awareness and understanding of options for the management of kidney failure among patients living with advanced CKD is a significant barrier to increasing the selection and use of home dialysis. Studies have shown that providing targeted comprehensive patient education before the onset of kidney failure can improve patients' awareness of kidney disease and substantially increase the informed utilization of home dialysis. Unfortunately, in the absence of validated evidence-based education protocols, outcomes associated with home dialysis use vary widely among published studies, potentially affecting the routine implementation and reporting of these services among patients with advanced CKD. This review provides pragmatic guidance on establishing effective patient-centered education programs to empower patients to make informed decisions about their KRT and, in turn, increase home dialysis use.

The benefit of planned dialysis to early survival on hemodialysis versus peritoneal dialysis: a nationwide prospective multicenter study in Korea

Optimal preparation is recommended for patients with advanced chronic kidney disease to minimize complications during dialysis initiation. This study evaluated the effects of planned dialysis initiation on survival in patients undergoing incident hemodialysis and peritoneal dialysis. Patients newly diagnosed with end-stage kidney disease who started dialysis were enrolled in a multicenter prospective cohort study in Korea. Planned dialysis was defined as dialysis therapy initiated with permanent access and maintenance of the initial dialysis modality. A total of 2892 patients were followed up for a mean duration of 71.9 ± 36.7 months and 1280 (44.3%) patients initiated planned dialysis. The planned dialysis group showed lower mortality than the unplanned dialysis group during the 1st and 2nd years after dialysis initiation (1st year: adjusted hazard ratio [aHR] 0.51; 95% confidence interval [CI] 0.37-0.72; P < 0.001; 2nd year: aHR 0.71; 95% CI 0.52-0.98, P = 0.037). However, 2 years after dialysis initiation, mortality did not differ between the groups. Planned dialysis showed a better early survival rate in hemodialysis patients, but not in peritoneal dialysis patients. Particularly, infection-related mortality was reduced only in patients undergoing hemodialysis with planned dialysis initiation. Planned dialysis has survival benefits over unplanned dialysis in the first 2 years after dialysis initiation, especially in patients undergoing hemodialysis. It improved infection-related mortality during the early dialysis period.

Utilization of Home Dialysis and Permanent Vascular Access at Dialysis Initiation Following a Structured CKD Education Program

Rationale & Objective

Treatment options for kidney failure are complex, and the majority of patients transitioning to dialysis lack important information about treatment options and are not prepared to make informed decisions about their care. Correspondingly, the majority of patients who start dialysis default to in-center hemodialysis using a central venous catheter for vascular access as the initial modality; furthermore, hospital admissions, mortality, and infections are exceedingly common over the first few months.

Study Design

Matched retrospective cohort study.

Setting & Patients

2,398 adult patients with chronic kidney disease (CKD) who attended a structured CKD education program and pair-matched control patients who did not receive education before starting dialysis between January 2018 and June 2019.

Exposure

CKD education attendance documented from 2 months (60 days)-3 years before dialysis initiation. CKD education consisted of a 1-time, 90-minute, inperson or virtual class.

Outcome

Primary outcomes were dialysis modality and vascular access type on the first day of dialysis (day 0) and at day 90 after dialysis initiation. Secondary outcomes included hospitalizations and deaths during the first year of receiving dialysis.

Analytical Approach

Generalized linear models were used to compare outcomes between patients receiving CKD education and controls.

Results

Compared with controls, CKD education patients were more frequently receiving home dialysis (38.5% vs 12.6%, P < 0.001) and used a permanent vascular access (57.9% vs 33.8%, P < 0.001) at dialysis initiation; differences were minimally attenuated and remained statistically significant at day 90. Hospitalization rates were lower among CKD education patients than among controls during the first year of receiving dialysis (1.00 vs 1.38 admissions per patient-year; P < 0.001). CKD education patients also had lower mortality over the first year of receiving dialysis (P < 0.001).

Limitations

Bias and confounding cannot fully be accounted for in an observational study. Analyses only included patients with commercial and Medicare insurance who received CKD care before dialysis initiation and may not be generalizable to other patient populations.

Conclusions

Our findings indicate that attending a CKD education class before starting dialysis resulted in positive clinical outcomes, including reduction in hospitalization and mortality rates. Broad implementation of structured CKD education may result in more patients choosing home dialysis as their first treatment option and reduce the risk of adverse outcomes in the crucial early period after dialysis initiation.

Peritoneal Dialysis Guidelines 2019 Part 1 (Position paper of the Japanese Society for Dialysis Therapy)

Approximately 10 years have passed since the Peritoneal Dialysis Guidelines were formulated in 2009. Much evidence has been reported during the succeeding years, which were not taken into consideration in the previous guidelines, e.g., the next peritoneal dialysis PD trial of encapsulating peritoneal sclerosis (EPS) in Japan, the significance of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs), the effects of icodextrin solution, new developments in peritoneal pathology, and a new international recommendation on a proposal for exit-site management. It is essential to incorporate these new developments into the new clinical practice guidelines. Meanwhile, the process of creating such guidelines has changed dramatically worldwide and differs from the process of creating what were “clinical practice guides.” For this revision, we not only conducted systematic reviews using global standard methods but also decided to adopt a two-part structure to create a reference tool, which could be used widely by the society’s members attending a variety of patients. Through a working group consensus, it was decided that Part 1 would present conventional descriptions and Part 2 would pose clinical questions (CQs) in a systematic review format. Thus, Part 1 vastly covers PD that would satisfy the requirements of the members of the Japanese Society for Dialysis Therapy (JSDT). This article is the duplicated publication from the Japanese version of the guidelines and has been reproduced with permission from the JSDT.

Impact of superimposed nephrological care to guidelines-directed management by primary care physicians of patients with stable chronic kidney disease: a randomized controlled trial

BACKGROUND

Optimal clinical care of patients with chronic kidney disease (CKD) requires collaboration between primary care physicians (PCPs) and nephrologists. We undertook a randomised trial to determine the impact of superimposed nephrologist care compared to guidelines-directed management by PCPs in CKD patients after hospital discharge.

METHODS

Stage 3b-4 CKD patients were enrolled during a hospitalization and randomised in two arms: Co-management by PCPs and nephrologists (interventional arm) versus management by PCPs with written instructions and consultations by nephrologists on demand (standard care). Our primary outcome was death or rehospitalisation within the 2 years post-randomisation. Secondary outcomes were: urgent renal replacement therapy (RRT), decline of renal function and decrease of quality of life at 2 years.

RESULTS

From November 2009 to the end of June 2013, we randomised 242 patients. Mean follow-up was 51 + 20 months. Survival without rehospitalisation, GFR decline and elective dialysis initiation did not differ between the two arms. Quality of life was also similar in both groups. Compared to randomised patients, those who either declined to participate in the study or were previously known by nephrologists had a worse survival.

CONCLUSION

These results do not demonstrate a benefit of a regular renal care compared to guided PCPs care in terms of survival or dialysis initiation in CKD patients. Increased awareness of renal disease management among PCPs may be as effective as a co-management by PCPs and nephrologists in order to improve the prognosis of moderate-to-severe CKD.

Complications and outcomes of urgent-start peritoneal dialysis in elderly patients with end-stage renal disease in China: a retrospective cohort study

OBJECTIVES

To investigate the complications and survival of elderly patients with end-stage renal disease (ESRD) who received urgent-start peritoneal dialysis (USPD) or urgent-start haemodialysis (USHD), and to explore the value of peritoneal dialysis (PD) as the emergent dialysis method for elderly patients with ESRD.

DESIGN

Retrospective cohort study.

SETTING

Two tertiary care hospitals in Shanghai, China.

PARTICIPANTS

Chinese patients (n=542) >65 years of age with estimated glomerular filtration rate ≤15 mL/min/m2 who received urgent-start dialysis between 1 January 2005 and 31 December 2015, and with at least 3 months of treatment. Patients who converted to other dialysis methods, regardless of the initial dialysis method, were excluded, as well as those with comorbidities that could significantly affect their dialysis outcomes.

PRIMARY AND SECONDARY OUTCOME MEASURES

Dialysis-related complications and survival were compared. Patients were followed until death, stopped PD, transfer to other dialysis centres, loss to follow-up or 31 December 2016.

RESULTS

There were 309 patients in the USPD group and 233 in the USHD group. The rate of dialysis-related complications within 30 days after catheter implantation was significantly lower in the USPD group compared with the USHD group (4.5% vs 10.7%, p=0.031). The 6-month and 1, 2 and 3-year survival rates were 95.3%, 91.4%, 86.6% and 64.8% in the USPD group, and 92.2%, 85.7%, 70.2% and 57.8% in the USHD group, respectively (p=0.023). The multivariable Cox regression analysis showed that USHD (HR=2.220, 95% CI 1.298 to 3.790; p=0.004), age (HR=1.025, 95% CI 1.013 to 1.043, p<0.001) and hypokalaemia (HR=0.678, 95% CI 0.487 to 0.970; p=0.032) were independently associated with death.

CONCLUSIONS

USPD was associated with slightly better survival compared with USHD. USPD was associated with fewer complications and better survival than USHD in elderly patients with ESRD.

The benefit of early survival on PD versus HD—Why this is (still) very important

There are a number of misconceptions around the identified early survival benefit of peritoneal dialysis (PD) relative to hemodialysis (HD), including that such benefits “even out in the end” since the relative risk of death over time eventually encompasses 1.0 (or even an estimate that is unfavorable to PD); that the early benefit is, in fact, most likely due to unmeasured confounding; and such benefits are only due to the influence of central venous catheters and “crash starters” in the HD group. In fact, the early survival benefit results in a substantial gain of patient life years in PD cohorts relative to HD ones, even if it the benefit appears to “even out in the end,” is relatively insensitive to unmeasured confounding, and persists even when the effects of central venous catheters are accounted for. In this review, the calculations and arguments are made to support these tenets. Survival on dialysis is still one of the most important considerations for all stakeholders in the end-stage kidney disease community, including patients who rank it among their top priorities. Shared decision-making is a fundamental patient right and requires both balanced information and an iterative mechanism for a consensual decision based on shared understanding and purpose. A cornerstone of this process should be an explicit discussion of the early survival benefit of PD relative to HD.

Risk Factors for Unplanned Dialysis Initiation: A Systematic Review of the Literature

Background:

Unplanned dialysis initiation is common in patients with chronic kidney disease (CKD).

Objective:

To determine common definitions and patient risk factors for unplanned dialysis.

Design:

Systematic review.

Setting:

MEDLINE, EMBASE, and the Cochrane Library were searched from inception to February 2018.

Patients:

Studies that included incident chronic dialysis patients or patients with CKD that cited a definition or examined risk factors for unplanned dialysis were included.

Measurements:

Definitions and criteria for unplanned dialysis reported across studies. Patient characteristics associated with unplanned dialysis.

Methods:

Two reviewers independently extracted data using a standardized data abstraction form and assessed study quality using a modified New Castle Ottawa Scale.

Results:

From 2797 citations, 48 met eligibility criteria. Reported definitions for unplanned dialysis were variable. Most publications cited dialysis initiation under emergency conditions and/or with a central venous catheter. The association of patient characteristics with unplanned dialysis was reported in 26 studies, 18 were retrospective and 21 included incident dialysis patients. The most common risk factors in univariate analyses were (number of studies) increased age (n = 7), cause of kidney disease (n = 6), presence of cardiovascular disease (n = 7), lower serum hemoglobin (n = 9), lower serum albumin (n = 10), higher serum phosphate (n = 6), higher serum creatinine or lower estimated glomerular filtration rate (eGFR) at dialysis initiation (n = 7), late referral (n = 5), lack of dialysis education (n = 6), and lack of follow-up in a predialysis clinic prior to dialysis initiation (n = 5). A minority of studies performed multivariable analyses (n = 10); the most common risk factors were increased age (n = 4), increased comorbidity score (n = 3), late referral (n = 5), and lower eGFR at dialysis initiation (n = 3).

Limitations:

Comparison of results across studies was limited by inconsistent definitions for unplanned dialysis. High-quality data on patient risk factors for unplanned dialysis are lacking.

Conclusions:

Well-designed prospective studies to determine modifiable risk factors are needed. The lack of a consensus definition for unplanned dialysis makes research and quality improvement initiatives in this area more challenging.

A Digital Modality Decision Program for Patients With Advanced Chronic Kidney Disease

BACKGROUND

Patient education regarding end-stage renal disease (ESRD) has the potential to reduce adverse outcomes and increase the use of in-home renal replacement therapies.

OBJECTIVE

This study aimed to investigate whether an online, easily scalable education program can improve patient knowledge and facilitate decision making regarding renal replacement therapy options.

METHODS

We developed a 4-week online, digital educational program that included written information, short videos, and social networking features. Topics included kidney transplant, conservative management, peritoneal dialysis, in-home hemodialysis, and in-center hemodialysis. We recruited patients with advanced chronic kidney disease (stage IV and V) to enroll in the online program, and we evaluated the feasibility and potential impact of the digital program by conducting pre- and postintervention surveys in areas of knowledge, self-efficacy, and choice of ESRD care.

RESULTS

Of the 98 individuals found to be eligible for the study, 28 enrolled and signed the consent form and 25 completed the study. The average age of participants was 65 (SD 15) years, and the average estimated glomerular filtration rate was 21 (SD 6) ml/min/1.73 m². Before the intervention, 32% of patients (8/25) were unable to make an ESRD treatment choice; after the intervention, all 25 participants made a choice. The proportion of persons who selected kidney transplant as the first choice increased from 48% (12/25) at intake to 84% (21/25) after program completion (P=.01). Among modality options, peritoneal dialysis increased as the first choice for 4/25 (16%) patients at intake to 13/25 (52%) after program completion (P=.004). We also observed significant increases in knowledge score (from 65 [SD 56] to 83 [SD 14]; P<.001) and self-efficacy score (from 3.7 [SD 0.7] to 4.3 [SD 0.5]; P<.001).

CONCLUSIONS

Implementation of a digital ESRD education program is feasible and may facilitate patients' decisions about renal replacement therapies. Larger studies are necessary to understand whether the program affects clinical outcomes.

Home Hemodialysis (HHD) Treatment as Effective yet Underutilized Treatment Modality in the United States

End-stage renal disease (ESRD) is a major health burden and its incidence has been increasing yearly reaching 120,000 cases in 2014. Home hemodialysis (HHD) is a treatment modality option that has been shown to contribute to numerous clinical benefits but is largely underutilized due to many contributing factors. The purpose of this review paper is to analyze the advantages and disadvantages of HHD and the reasons for its low utilization with a special focus on its socioeconomic impact as compared to facility hemodialysis. Key factors contributing to HHD underutilization are related to the reimbursement system of the facility and nephrologists as well as the underutilization of the pre-dialysis educational benefit. Based on this comprehensive review of the literature, we propose several suggestions which may contribute to the expansion of HHD treatment modality.

Offering Patients Therapy Options in Unplanned Start (OPTiONS): Implementation of an educational program is feasible and effective

Background

Patients with unplanned dialysis start (UPS) have worse clinical outcomes than non-UPS patients, and receive peritoneal dialysis (PD) less frequently. In the OPTiONS study of UPS patients, an educational programme (UPS-EP) aiming at improving care of UPS patients by facilitating care pathways and enabling informed choice of dialysis modality was implemented. We here report on impact of UPS-EP on modality choice and clinical outcomes in UPS patients.

Methods

This non-interventional, prospective, multi-center, observational study included 270 UPS patients from 26 centers in 6 European countries (Austria, Germany, Denmark, France, United Kingdom and Sweden) who prior to inclusion presented acutely, or were being followed by nephrologists but required urgent dialysis commencement by an acutely placed CVC or PD catheter. Effects of UPS-EP on choice and final decision of dialysis therapy and outcomes within 12 months of follow up were analysed.

Results

Among 270 UPS patients who had an unplanned start to dialysis, 214 were able to receive and 203 complete UPS-EP while 56 patients - who were older (p = 0.01) and had higher Charlson comorbidity index (CCI; p < 0.01) - did not receive UPS-EP. Among 177 patients who chose dialysis modality after UPS-EP, 103 (58%) chose PD (but only 86% of them received PD) and 74 (42%) chose HD (95% received HD). Logistic regression analysis showed that diabetes 1.88 (1.05 – 3.37) and receiving UPS-EP, OR = 4.74 (CI, 2.05 – 10.98) predicted receipt of PD. Patients choosing PD had higher CCI (p = 0.01), higher prevalence of congestive heart failure (p < 0.01) and myocardial infarction (p = 0.02), and were more likely in-patients (p = 0.02) or referred from primary care (p = 0.02). One year survival did not differ significantly between PD and HD patients. Peritonitis and bacteraemia rates were better than international guideline standards.

Conclusions

UPS-EP predicted patient use of PD but 14% of those choosing PD after UPS-EP still did not receive the modality they preferred. Patient survival in patients choosing and/or receiving PD was similar to HD despite age and comorbidity disadvantages of the PD groups.

Influencia de la Consulta de Enfermedad Renal Crónica avanzada en la elección de modalidad de terapia renal sustitutiva

Introducción: La enfermedad renal crónica constituye un problema de salud pública por su elevada incidencia y prevalencia, importante morbimortalidad y coste asistencial. Un aspecto fundamental para el paciente es la elección de modalidad de terapia sustitutiva renal. En este sentido, la consulta de enfermedad renal crónica avanzada o prediálisis, puede jugar un papel fundamental. Objetivo: Conocer producción científica sobre la influencia de la consulta de enfermedad renal crónica avanzada en la elección de modalidad de diálisis por parte del paciente. Metodología: Revisión bibliográfica para la que se realizaron búsquedas en las bases de datos de PubMed, Scielo, Science Direct, Proquest y Google Académico. Se analizaron los artículos que trataban la consulta prediálisis, variables que influyeran en la elección de modalidad de diálisis y satisfacción del paciente. Resultados: Se han revisado 25 artículos publicados en los años 2002-2014, de diseño observacional descriptivo y de cohortes. Se ha encontrado relación en la elección de las técnicas domiciliarias con la existencia de un programa de educación prediálisis, la información que ofrece enfermería, la entrada programada en diálisis, menor edad, menor comorbilidad y factores socioeconómicos o estructurales. Conclusion: Los factores que favorecen la elección de las técnicas de diálisis domiciliarias son la existencia de consulta de enfermedad renal crónica avanzada y la referencia oportuna del paciente a dicha consulta, ser joven, menor comorbilidad y la necesidad de contención de costes. Esta elección se ve perjudicada por factores estructurales. Las terapias domiciliarias producen mayor satisfacción en los pacientes.

Type of Referral, Dialysis Start and Choice of Renal Replacement Therapy Modality in an International Integrated Care Setting

INTRODUCTION

Integrated Care Settings (ICS) provide a holistic approach to the transition from chronic kidney disease into renal replacement therapy (RRT), offering at least both types of dialysis.

OBJECTIVES

To analyze which factors determine type of referral, modality provision and dialysis start on final RRT in ICS clinics.

METHODS

Retrospective analysis of 626 patients starting dialysis in 25 ICS clinics in Poland, Hungary and Romania during 2012. Scheduled initiation of dialysis with a permanent access was considered as planned RRT start.

RESULTS

Modality information (80% of patients) and renal education (87%) were more frequent (p<0.001) in Planned (P) than in Non-Planned (NP) start. Median time from information to dialysis start was 2 months. 89% of patients started on hemodialysis, 49% were referred late to ICS (<3 months from referral to RRT) and 58% were NP start. Late referral, non-vascular renal etiology, worse clinical status, shorter time from information to RRT and less peritoneal dialysis (PD) were associated with NP start (p<0.05). In multivariate logistic regression analysis, P start (p≤0.05) was associated with early referral, eGFR >8.2 ml/min, >2 months between information and RRT initiation and with vascular etiology after adjustment for age and gender. "Optimal care," defined as ICS follow-up >12 months plus modality information and P start, occurred in 23%.

CONCLUSIONS

Despite the high rate of late referrals, information and education were widely provided. However, NP start was high and related to late referral and may explain the low frequency of PD.

The anticipated and the lived experience of home and in-centre haemodialysis: Is there a disconnect?

This qualitative study aimed to explore home haemodialysis and in-centre haemodialysis patients’ experience, to illuminate barriers and facilitators in the uptake and maintenance of home haemodialysis. Thirty-two semi-structured interviews with patients receiving home haemodialysis or in-centre haemodialysis were analysed using framework analysis. Four themes emerged: ‘perceptions of self’; ‘impact of haemodialysis on family’; ‘perceived advantages and disadvantages of home haemodialysis and in-centre haemodialysis’ and ‘practical issues and negotiating haemodialysis’. The lived experience of home haemodialysis was in contrast to the lived experience of in-centre haemodialysis and to the anticipated experience of home haemodialysis, highlighting patient factors that contributed to under-usage of home haemodialysis.

Overcoming the Underutilisation of Peritoneal Dialysis

Peritoneal dialysis is troubled with declining utilisation as a form of renal replacement therapy in developed countries. We review key aspects of therapy evidenced to have a potential to increase its utilisation. The best evidence to repopulate PD programmes is provided for the positive impact of timely referral and systematic and motivational predialysis education: average odds ratio for instituting peritoneal dialysis versus haemodialysis was 2.6 across several retrospective studies on the impact of predialysis education. Utilisation of PD for unplanned acute dialysis starts facilitated by implantation of peritoneal catheters by interventional nephrologists may diminish the vast predominance of haemodialysis done by central venous catheters for unplanned dialysis start. Assisted peritoneal dialysis can improve accessibility of home based dialysis to elderly, frail, and dependant patients, whose quality of life on replacement therapy may benefit most from dialysis performed at home. Peritoneal dialysis providers should perform close monitoring, preventing measures, and timely prophylactic therapy in patients judged to be prone to EPS development. Each peritoneal dialysis programme should regularly monitor, report, and act on key quality indicators to manifest its ability of constant quality improvement and elevate the confidence of interested patients and financing bodies in the programme.

The Concordance between Patients' Renal Replacement Therapy Choice and Definitive Modality: Is It a Utopia?

INTRODUCTION

It is desirable for patients to play active roles in the choice of renal replacement therapy (RRT). Patient decision aid tools (PDAs) have been developed to allow the patients to choose the option best suited to their individual needs.

MATERIAL AND METHODS

An observational, prospective registry was conducted in 26 Spanish hospitals between September 2010 and May 2012. The results of the patients' choice and the definitive RRT modality were registered through the progressive implementation of an Education Process (EP) with PDAs designed to help Chronic Kidney Disease (CKD) patients choose RRT.

RESULTS

Patients included in this study: 1044. Of these, 569 patients used PDAs and had made a definitive choice by the end of registration. A total of 88.4% of patients chose dialysis [43% hemodialysis (HD) and 45% peritoneal dialysis (PD)] 3.2% preemptive living-donor transplant (TX), and 8.4% conservative treatment (CT). A total of 399 patients began RRT during this period. The distribution was 93.4% dialysis (53.6% HD; 40% PD), 1.3% preemptive TX and 5.3% CT. The patients who followed the EP changed their mind significantly less often [kappa value of 0.91 (95% CI, 0.86-0.95)] than those who did not follow it, despite starting unplanned treatment [kappa value of 0.85 (95% CI, 0.75-0.95]. A higher agreement between the final choice and a definitive treatment was achieved by the EP and planned patients [kappa value of 0.93 (95% CI, 0.89-0.98)]. Those who did not go through the EP had a much lower index of choosing PD and changed their decision more frequently when starting definitive treatment [kappa value of 0.73 (95% CI, 0.55-0.91)].

CONCLUSIONS

Free choice, assisted by PDAs, leads to a 50/50 distribution of PD and HD choice and an increase in TX choice. The use of PDAs, even with an unplanned start, achieved a high level of concordance between the chosen and definitive modality.

Cost of renal replacement: how to help as many as possible while keeping expenses reasonable?

The treatment of kidney diseases consumes a substantial amount of the health budget for a relatively small fraction of the overall population. If the nephrological community and society do not develop mechanisms to contain those costs, it will become impossible to continue assuring optimal outcomes and quality of life while treating all patients who need it. In this article, we describe several mechanisms to maintain sustainability of renal replacement therapy. These include (i) encouragement of transplantation after both living and deceased donation; (ii) stimulation of alternative dialysis strategies besides classical hospital haemodialysis, such as home haemodialysis, peritoneal dialysis or self-care and necessitating less reimbursement; (iii) promotion of educational activities guiding the patients towards therapies that are most suited for them; (iv) consideration of one or more of cost containment incentives such as bundling of reimbursement (if not affecting quality of the treatment), timely patient referral, green dialysis, start of dialysis based on clinical necessity rather than renal function parameters and/or prevention of CKD or its progression; (v) strategically planned adaptations to the expected growth of the ageing population in need of renal replacement; (vi) the necessity for support of research in the direction of helping as large as possible patient populations for acceptable costs; and (vii) the need for more patient-centred approaches. We also extend the discussion to the specific situation of kidney diseases in low- and middle-income countries. Finally, we point to the dramatic differences in accessibility and reimbursement of different modalities throughout Europe. We hope that this text will offer a framework for the nephrological community, including patients and nurses, and the concerned policy makers and caregivers on how to continue reaching all patients in need of renal replacement for affordable expenses.

The impact of patient preference on dialysis modality and hemodialysis vascular access

Background

Home-based dialysis, including peritoneal dialysis (PD) and home hemodialysis (HHD), is associated with improved health related quality of life and reduced health resource costs. It is uncertain to what extent initial preferences for dialysis modality influence the first dialysis therapy actually utilized. We examined the relationship between initial dialysis modality choice and first dialysis therapy used.

Methods

Patients with chronic kidney disease (CKD) from a single centre who started dialysis after receiving modality education were included in this study. Multivariable logistic regression models were constructed to assess the independent association of patient characteristics and initial dialysis modality choice with actual dialysis therapy used and starting hemodialysis (HD) with a central venous catheter (CVC).

Results

Of 299 eligible patients, 175 (58.5%) initially chose a home-based therapy and 102 (58.3%) of these patients’ first actual dialysis was a home-based therapy. Of the 89 patients that initially chose facility-based HD, 84 (94.4%) first actual dialysis was facility-based HD. The adjusted odds ratio (OR) for first actual dialysis as a home-based therapy was 29.0 for patients intending to perform PD (95% confidence interval [CI] 10.7-78.8; p < 0.001) and 12.4 for patients intending to perform HHD (95% CI 3.29-46.6; p < 0.001). Amongst patients whose first actual dialysis was HD, an initial choice of PD or not choosing a modality was associated with an increased risk of starting dialysis with a CVC (adjusted OR 3.73, 95% CI 1.51-9.21; p = 0.004 and 4.58, 95% CI 1.53-13.7; p = 0.007, respectively).

Conclusions

Although initially choosing a home-based therapy substantially increases the probability of the first actual dialysis being home-based, many patients who initially prefer a home-based therapy start with facility-based HD. Programs that continually re-evaluate patient preferences and reinforce the values of home based therapies that led to the initial preference may improve home-based therapy uptake and improve preparedness for starting HD.

Geographic and facility-level variation in the use of peritoneal dialysis in Canada: a cohort study

BACKGROUND

Peritoneal dialysis is associated with similar survival and similar improvement in quality of life and is less costly compared with in-centre hemodialysis. We examined facility and geographic variation in the use of peritoneal dialysis in Canada.

METHODS

We analyzed data from the Canadian Organ Replacement Register for the period January 2001 to December 2010. We identified patients for whom peritoneal dialysis was the primary modality at 90 days after initiation of dialysis. We used multilevel models to evaluate variation in use of peritoneal dialysis by facility and geographic region.

RESULTS

We analyzed data for 31 778 incident dialysis patients at 56 facilities in 13 geographic regions across Canada. Use of peritoneal dialysis at 90 days varied considerably across geographic regions (range 19.8%-36.1%) and declined over time, from 28.8% in 2001 to 22.5% in 2010. After adjustment for case mix and facility-level quality indicators, 9.3% and 3.4% of the variability was attributable to facility and geographic factors, respectively. In adjusted models, there was a substantial difference between geographic regions with the lowest and highest peritoneal dialysis use (odds ratio for high use 1.51, 95% confidence interval [CI] 1.33-1.73 v. odds ratio for low use 0.69, 95% CI 0.60-0.79).

INTERPRETATION

In Canada, substantial variability in the use of peritoneal dialysis attributable to facility and geographic region was not explained by differences in patient case mix. An opportunity exists to optimize use of this cost-effective therapy through changes in policy and standardization of criteria for initiation of peritoneal dialysis.

Does a predialysis education program increase the number of pre-emptive renal transplantations?

OBJECTIVES

Renal transplantation (RT) is the most appropriate form of treatment for end-stage renal disease (ESRD). Pre-emptive RT decreases the rates of delayed graft function and acute rejection episodes, increasing patient and graft survival, while reducing costs and complications associated with dialysis. In this study, we investigated the relationship between a predialysis education program (PDEP) for patients and their relatives and pre-emptive RT.

METHODS

We divided 88 live donor kidney transplant recipients into 2 groups: transplantation without education (non-PDEP group; n = 27), and enrollment in an education program before RT (PDEP group n = 61).

RESULTS

Five patients in the non-PDEP group underwent pre-emptive transplantation, versus 26 of the PDEP group. The rate of pre-emptive transplantations was significantly higher among the educated (42.62%) versus the noneducated group (18.51%; P < .001).

CONCLUSION

PDEP increased the number of pre-emptive kidney transplantations among ESRD patients.

PD First: peritoneal dialysis as the default transition to dialysis therapy

Peritoneal dialysis (PD) and in-center hemodialysis (HD) are accepted as clinically equivalent dialysis modalities, yet in-center HD is the predominant renal replacement therapy (RRT) modality offered to new end-stage renal disease (ESRD) patients in the United States and most other industrialized nations. This predominance has little to do with clinical outcomes, patient choice, cost, or quality of life. It has been driven by ease of HD initiation, physician experience and training, inadequate pre-ESRD patient education, ample in-center HD capacity, and lack of adequate infrastructure for PD-related care. As compared with in-center HD, PD is a widely applicable, yet underutilized modality of RRT that provides comparable clinical outcomes, superior quality of life measures, significant cost savings, and many other unmeasured advantages. A "PD First" approach not only has advantages for patients but also physicians, healthcare systems, and society. In this review, we will summarize evidence demonstrating that PD should be the default modality when new ESRD patients are transitioning to dialysis therapy when preemptive transplantation is not an option and highlight the essential infrastructural requirements to allow for a "PD First" model.

Barriers to successful implementation of care in home haemodialysis (BASIC-HHD):1. Study design, methods and rationale

Background

Ten years on from the National Institute of Health and Clinical Excellence’ technology appraisal guideline on haemodialysis in 2002; the clinical community is yet to rise to the challenge of providing home haemodialysis (HHD) to 10-15% of the dialysis cohort. The renal registry report, suggests underutilization of a treatment type that has had a lot of research interest and several publications worldwide on its apparent benefit for both physical and mental health of patients. An understanding of the drivers to introducing and sustaining the modality, from organizational, economic, clinical and patient perspectives is fundamental to realizing the full benefits of the therapy with the potential to provide evidence base for effective care models. Through the BASIC-HHD study, we seek to understand the clinical, patient and carer related psychosocial, economic and organisational determinants of successful uptake and maintenance of home haemodialysis and thereby, engage all major stakeholders in the process.

Design and methods

We have adopted an integrated mixed methodology (convergent, parallel design) for this study. The study arms include a. patient; b. organization; c. carer and d. economic evaluation. The three patient study cohorts (n = 500) include pre-dialysis patients (200), hospital haemodialysis (200) and home haemodialysis patients (100) from geographically distinct NHS sites, across the country and with variable prevalence of home haemodialysis. The pre-dialysis patients will also be prospectively followed up for a period of 12 months from study entry to understand their journey to renal replacement therapy and subsequently, before and after studies will be carried out for a select few who do commence dialysis in the study period. The process will entail quantitative methods and ethnographic interviews of all groups in the study. Data collection will involve clinical and biomarkers, psychosocial quantitative assessments and neuropsychometric tests in patients. Organizational attitudes and dialysis unit practices will be studied together with perceptions of healthcare providers on provision of home HD. Economic evaluation of home and hospital haemodialysis practices will also be undertaken and we will apply scenario ("what … if") analysis using system dynamics modeling to investigate the impact of different policy choices and financial models on dialysis technology adoption, care pathways and costs. Less attention is often given to the patient’s carers who provide informal support, often of a complex nature to patients afflicted by chronic ailments such as end stage kidney disease. Engaging the carers is fundamental to realizing the full benefits of a complex, home-based intervention and a qualitative study of the carers will be undertaken to elicit their fears, concerns and perception of home HD before and after patient’s commencement of the treatment. The data sets will be analysed independently and the findings will be mixed at the stage of interpretation to form a coherent message that will be informing practice in the future.

Discussion

The BASIC-HHD study is designed to assemble pivotal information on dialysis modality choice and uptake, investigating users, care-givers and care delivery processes and study their variation in a multi-layered analytical approach within a single health care system. The study results would define modality specific service and patient pathway redesign.

Effect of timing of dialysis commencement on clinical outcomes of patients with planned initiation of peritoneal dialysis in the IDEAL trial

BACKGROUND

Since the mid-1990s, early dialysis initiation has dramatically increased in many countries. The Initiating Dialysis Early and Late (IDEAL) study demonstrated that, compared with late initiation, planned early initiation of dialysis was associated with comparable clinical outcomes and increased health care costs. Because residual renal function is a key determinant of outcome and is better preserved with peritoneal dialysis (PD), the present pre-specified subgroup analysis of the IDEAL trial examined the effects of early-compared with late-start dialysis on clinical outcomes in patients whose planned therapy at the time of randomization was PD.

METHODS

Adults with an estimated glomerular filtration rate (eGFR) of 10 - 15 mL/min/1.73 m(2) who planned to be treated with PD were randomly allocated to commence dialysis at an eGFR of 10 - 14 mL/min/1.73 m(2) (early start) or 5 - 7 mL/min/1.73 m(2) (late start). The primary outcome was all-cause mortality.

RESULTS

Of the 828 IDEAL trial participants, 466 (56%) planned to commence PD and were randomized to early start (n = 233) or late start (n = 233). The median times from randomization to dialysis initiation were, respectively, 2.03 months [interquartile range (IQR):1.67 - 2.30 months] and 7.83 months (IQR: 5.83 - 8.83 months). Death occurred in 102 early-start patients and 96 late-start patients [hazard ratio: 1.04; 95% confidence interval (CI): 0.79 - 1.37]. No differences in composite cardiovascular events, composite infectious deaths, or dialysis-associated complications were observed between the groups. Peritonitis rates were 0.73 episodes (95% CI: 0.65 - 0.82 episodes) per patient-year in the early-start group and 0.69 episodes (95% CI: 0.61 - 0.78 episodes) per patient-year in the late-start group (incidence rate ratio: 1.19; 95% CI: 0.86 - 1.65; p = 0.29). The proportion of patients planning to commence PD who actually initiated dialysis with PD was higher in the early-start group (80% vs 70%, p = 0.01).

CONCLUSION

Early initiation of dialysis in patients with stage 5 chronic kidney disease who planned to be treated with PD was associated with clinical outcomes comparable to those seen with late dialysis initiation. Compared with early-start patients, late-start patients who had chosen PD as their planned dialysis modality were less likely to commence on PD.

Effects of a pre-dialysis patient education program on the relative frequencies of dialysis modalities

BACKGROUND

Pre-dialysis education can guide the choice of the dialysis modality best tailored to meet the needs and preferences of individual patients with chronic kidney disease.

METHODS

In a retrospective single-center cohort study, we evaluated the impact of a pre-dialysis education program on the incidence rates of patients using hemodialysis (HD) and peritoneal dialysis (PD) in our unit. The frequency distribution of dialysis modalities between people attending our education program and people not attending the program (control group) was analyzed for the 4-year period 2004 - 2008.

RESULTS

From among all the incident chronic kidney disease 5D patients presenting during the 4-year period, we analyzed 227 who started dialysis either with an arteriovenous fistula or a PD catheter. In that cohort, 70 patients (30.8%) took part in the education program, and 157 (69.2%) did not receive structured pre-dialysis counseling. In the group receiving education, 38 patients (54.3%) started with PD, and 32 (45.7%), with HD. In the standard-care group not receiving education, 44 patients (28%) started with PD, and 113 (72%), with HD (p < 0.001).

CONCLUSIONS

Our multidisciplinary pre-dialysis program had a significant impact on the frequency distribution of dialysis modalities, increasing the proportion of patients initiating dialysis with PD.

Outcome of the sub-optimal dialysis starter on peritoneal dialysis. Report from the French Language Peritoneal Dialysis Registry (RDPLF)

BACKGROUND

This study was carried out to examine the association of sub-optimal dialysis initiation of peritoneal dialysis (PD) with all the possible outcomes on PD using survival analysis in the presence of competing risks.

METHODS

This was a retrospective cohort study based on the data of the French Language Peritoneal Dialysis Registry. We analysed 8527 incident patients starting PD between January 2002 and December 2010. The end of the observation period was 01 June 2011. Times from the start of PD to death, transplantation, transfer to haemodialysis (HD) and first peritonitis episode were calculated. The sub-optimal dialysis initiation was defined by a period of <30 days on HD before PD initiation.

RESULTS

Among 8527 patients, there were 568 patients who started PD after <30 days on HD. There were 6562 events: 3078 deaths, 2136 transfers to HD, 1348 renal transplantations. When using a Fine and Gray model, sub-optimal dialysis start, early peritonitis and transplant failure were associated with a higher sub-distribution relative hazard of technique failure. There was no association between the sub-optimal dialysis start and the sub-distribution hazard of death or transplantation. In the multivariate analysis using a Fine and Gray regression model, the sub-optimal dialysis start was not associated with a higher sub distribution relative hazard of peritonitis.

CONCLUSIONS

Sub-optimal dialysis initiation is neither associated with a higher risk of death nor with a lower risk of renal transplantation. Sub-optimal PD patients had a higher risk of transfer to HD.

Effectiveness of multidisciplinary care for chronic kidney disease in Taiwan: a 3-year prospective cohort study

BACKGROUND

Previous studies have demonstrated that multidisciplinary pre-dialysis education and team care may slow the decline in renal function for chronic kidney disease (CKD). Our study compared clinical outcomes of CKD patients between multidisciplinary care (MDC) and usual care in Taiwan.

METHODS

In this 3-year prospective cohort study from 2008 to 2010, we recruited 1056 CKD subjects, aged 20-80 years, from five hospitals, who received either MDC or usual care, had an estimated glomerular filtration rate (eGFR) <60 mL/min, were matched one to one with the propensity score including gender, age, eGFR and co-morbidity diseases. The MDC team was under-cared based on NKF K/DOQI clinical practice guidelines and the Taiwanese pre-end-stage renal disease (ESRD) care program. The incidence of progression to ESRD (initiation of dialysis) and mortality was compared between two groups. We also monitored blood pressure control, the rate of renal function decline, lipid profile, hematocrit and mineral bone disease control.

RESULTS

Participants were prone to be male (64.8%) with a mean age of 65.1 years and 33.1 months of mean follow-up. The MDC group had higher prescription rates of angiotensin-converting enzyme inhibitor/angiotensin receptor blocker (ACEI/ARB), phosphate binder, vitamin D3, uric acid lower agents and erythropoietin-stimulating therapy and better control in secondary hyperparathyroidism. The decline of renal function in advanced stage CKD IV and V was also slower in the MDC group (-5.1 versus -7.3 mL/min, P = 0.01). The use of temporary dialysis catheter was higher in the usual care group, and CKD patients under MDC intervention exhibited a greater willingness to choose peritoneal dialysis modality. A Cox regression revealed that the MDC group was associated with a 40% reduction in the risk of hospitalization due to infection, and a 51% reduction in patient mortality, but a 68% increase in the risk of initiation dialysis when compared with the usual care group.

CONCLUSIONS

MDC patients were found to have more effective medication prescription according to K/DOQI guidelines and slower renal function declines in advanced/late-stage CKD. After MDC intervention, CKD patients had a better survival rate and were more likely to initiate renal replacement therapy (RRT) instead of mortality.

Perspectives of patients, families, and health care professionals on decision-making about dialysis modality--the good, the bad, and the misunderstandings!

OBJECTIVES

This study explored the factors influencing decision-making about dialysis modality, integrating the perspectives of patients, their families, and health care professionals within an Asian population. The study further sought to understand the low penetration rate of peritoneal dialysis (PD) in Singapore. ♢

METHODS

A sample of 59 participants comprising pre-dialysis patients, dialysis patients, caregivers, and health care professionals (HCPs) participated in semi-structured interviews to explore the decision-making process and their views about various dialysis modalities. Data were thematically analyzed using NVivo9 (QSR International, Doncaster, Australia) to explore barriers to and facilitators of various dialysis modalities and decisional support needs. ♢

RESULTS

Fear of infection, daily commitment to PD, and misperceptions of PD emerged as barriers to PD. Side effects, distance to dialysis centers, and fear of needling and pain were barriers to hemodialysis (HD). The experiences of other patients, communicated informally or opportunistically, influenced the preferences and choices of patients and family members for a dialysis modality. Patients and families value input from HCPs and yet express strong needs to discuss subjective experiences of life on dialysis (PD or HD) with other patients before making a decision about dialysis modality. ♢

CONCLUSIONS

Pre-dialysis education should expand its focus on the family as the unit of care and should provide opportunities for interaction with dialysis patients and for peer-led learning. Barriers to PD, especially misperceptions and misunderstandings, can be targeted to improve PD uptake.

Effect of multidisciplinary pre-dialysis education in advanced chronic kidney disease: Propensity score matched cohort analysis

AIM

  The mortality and morbidity of end-stage renal failure patients remains high despite recent advances in pre-dialysis care. Previous studies suggesting a positive effect of pre-dialysis education were limited by unmatched comparisons between the recipients and non-recipients of education. The present study aimed to clarify the roles of the multidisciplinary pre-dialysis education (MPE) in chronic kidney disease patients.

METHODS

  We performed a retrospective single centre study, enrolling 1218 consecutive pre-dialysis chronic kidney disease patients, between July 2007 and Feb 2008 and followed them up to 30 months. By using propensity score matching, we matched 149 recipient- and non-recipient pairs from 1218 patients. The incidences of renal replacement therapy, mortality, cardiovascular event and infection were compared between recipients and non-recipients of MPE.

RESULTS

  Renal replacement therapy was initiated in 62 and 64 patients in the recipients and non-recipients, respectively (P > 0.05). The MPE reduced unplanned urgent dialysis (8.7% vs 24.2%, P < 0.001) and shortened hospital days (2.16 vs 5.05 days/patient per year). MPE recipients had a better metabolic status at the time of initiating renal replacement therapy. Although no significant survival advantage from MPE was exhibited, MPE recipients had lower incidence of cardiovascular events (adjusted hazard ratio, 0.24; 95% confidence interval (CI), 0.08 to 0.78; P = 0.017), and a tendency toward a lower infection rate (adjusted hazard ratio, 0.44; 95% CI, 0.17 to 1.11; P = 0.083).

CONCLUSION

  MPE was associated with better clinical outcomes in terms of urgent dialysis, cardiovascular events and infection.

Cost-effectiveness analysis of the Spanish renal replacement therapy program

BACKGROUND

We undertook a cost-effectiveness analysis of the Spanish Renal Replacement Therapy (RRT) program for end-stage renal disease patients from a societal perspective. The current Spanish situation was compared with several hypothetical scenarios.

METHODS

A Markov chain model was used as a foundation for simulations of the Spanish RRT program in three temporal horizons (5, 10, and 15 years). The current situation (scenario 1) was compared with three different scenarios: increased proportion of overall scheduled (planned) incident patients (scenario 2); constant proportion of overall scheduled incident patients, but increased proportion of scheduled incident patients on peritoneal dialysis (PD), resulting in a lower proportion of scheduled incident patients on hemodialysis (HD) (scenario 3); and increased overall proportion of scheduled incident patients together with increased scheduled incidence of patients on PD (scenario 4).

RESULTS

The incremental cost-effectiveness ratios (ICERs) of scenarios 2, 3, and 4, when compared with scenario 1, were estimated to be, respectively, -€83 150, -€354 977, and -€235 886 per incremental quality-adjusted life year (ΔQALY), evidencing both moderate cost savings and slight effectiveness gains. The net health benefits that would accrue to society were estimated to be, respectively, 0.0045, 0.0211, and 0.0219 ΔQALYs considering a willingness-to-pay threshold of €35 000/ΔQALY.

CONCLUSIONS

Scenario 1, the current Spanish situation, was dominated by all the proposed scenarios. Interestingly, scenarios 3 and 4 showed the best results in terms of cost-effectiveness. From a cost-effectiveness perspective, an increase in the overall scheduled incidence of RRT, and particularly that of PD, should be promoted.

When to initiate dialysis--is early start always better?

The question when to initiate dialysis is attracting increasing attention. In recent years, there has been a tendency to initiate dialysis earlier in terms of estimated glomerular filtration rate (eGFR) in an attempt to achieve better patient outcomes. However, several observational studies and one randomized controlled trial have found no benefit for early dialysis initiation. On the contrary, they have found that starting dialysis with a higher eGFR is associated with increased mortality. These studies need to be carefully interpreted in light of their reliance on eGFR to estimate kidney function at dialysis initiation. The decision to start dialysis should not be based solely on a predefined eGFR value, but more importantly on a careful clinical assessment of the individual patient.

Cost analysis of the Spanish renal replacement therapy programme

BACKGROUND

A cost analysis of the Spanish Renal Replacement Therapy (RRT) programme in the year 2010, for end-stage renal disease (ESRD) patients, was performed from the perspective of the Public Administration.

METHODS

The costs associated with each RRT modality [hemodialysis (HD), peritoneal dialysis (PD) and kidney transplantation (Tx)] were analysed. The Spanish ESRD incidence and prevalence figures in the year 2010 were forecasted in order to enable the calculation of an aggregate cost for each modality. Costs were mainly computed based on a review of the existing literature and of the Official Bulletins of the Spanish Autonomous Communities. Data from Oblikue Consulting eSalud health care costs database and from several Spanish public sources were also employed.

RESULTS

In the year 2010, the forecasted incidence figures for HD, PD and Tx were 5409, 822 and 2317 patients, respectively. The forecasted prevalence figures were 22,582, 2420 and 24,761 patients, respectively. The average annual per-patient costs (incidence and prevalence) were €2651 and €37,968 (HD), €1808 and €25,826 (PD) and €38,313 and €6283 (Tx). Indirect costs amounted to €8929 (HD), €7429 (PD) and €5483 (Tx). The economic impact of the Spanish RRT programme on the Public Administration budget was estimated at ~€1829 million (indirect costs included): €1327 (HD), €109 (PD) and €393 (Tx) million.

CONCLUSIONS

HD accounted for >70% of the aggregate costs of the Spanish RRT programme in 2010. From a costs minimization perspective, it would be preferable if the number of incident and prevalent patients in PD were increased.

Patient INformation about Options for Treatment (PINOT): a prospective national study of information given to incident CKD Stage 5 patients

BACKGROUND

Informed decision-making requires the presentation of all possible courses of action; however, it is unclear what proportion of Stage 5 chronic kidney disease (CKD) patients are routinely informed of all their treatment options. The aim of this study was to determine the effect of patient and unit characteristics on the type and timing of information provided.

METHODS

A prospective national multi-centre study of information was given to incident pre-emptive transplant, dialysis and conservatively managed patients in Australian renal units, over a 3-month period.

RESULTS

Sixty-six of 73 renal units participated in the study. Seven hundred and twenty-one incident CKD Stage 5 patients including 102 who chose not to dialyse were identified. Of these, 603 (84%) were presented with information about their options prior to commencing treatment. Three quarters (n = 543) were presented with home dialysis, one-third (n = 230) pre-emptive transplantation and 65% (n = 470) were informed about conservative care as an option. Patients were more likely to receive information prior to commencing treatment if they were known to a nephrologist for more than 3 months (OR 7.29, 95% CI 3.86-13.79) or were treated in small units with < 100 dialysis patients (OR 2.40, 95% CI 1.26-4.60). The mean estimated glomerular filtration rate at the time information was first presented was 13.3 mL/min/1.73 m(2) (95% CI 12.7-13.8) and mean serum creatinine was 449 μmol/L (95% CI 431-467).

CONCLUSIONS

Most Australian patients were informed of their treatment options prior to starting treatment, albeit in late stage CKD. Earlier education and support for informed decision-making may help optimize the uptake of pre-emptive transplantation and home dialysis therapies.

'Reality and desire' in the care of advanced chronic kidney disease

There is a long distance between the actual worldwide reality in advanced chronic kidney disease care and the desire of how these patients should be managed to decrease cardiovascular and general morbidity and mortality. Implementation of adequate infrastructures may improve clinical outcomes and increase the use of home renal replacement therapies (RRT). Current pitfalls should be addressed to optimise care: inadequate medical training for nephrological referral and RRT selection, late referral to nephrologists, inadequate patient education for choice of RRT modality, lack of multidisciplinary advanced kidney disease clinics and lack of programmed RRT initiation. These deficiencies generate unintended consequences, such as inequality of care and limitations in patient education and selection-choice for RRT technique with limited use of peritoneal dialysis. Multidisciplinary advanced kidney disease clinics may have a direct impact on patient survival, morbidity and quality of life. There is a common need to reduce health care costs and scenarios increasing PD incidence show better efficiency. The following proposals may help to improve the current situation: defining the scope of the problem, disseminating guidelines with specific targets and quality indicators, optimising medical speciality training, providing adequate patient education, specially through the use of general decision making tools that will allow patients to choose the best possible RRT in accordance with their values, preferences and medical advice, increasing planned dialysis starts and involving all stakeholders in the process.

Multidisciplinary predialysis education decreases the incidence of dialysis and reduces mortality--a controlled cohort study based on the NKF/DOQI guidelines

BACKGROUND

Observational studies have demonstrated that multidisciplinary predialysis education (MPE) improves the post-dialysis outcomes of chronic kidney disease (CKD) patients. However, the beneficial effect of MPE remains unclear in prospective controlled studies.

METHODS

All CKD patients who visited the outpatient nephrology clinics at two centres of the Chang Gung Memorial Hospital in 2006-07 were enrolled. The incidence of dialysis and mortality were compared between MPE recipients and non-recipients. The content of the MPE was standardized in accordance with the NKF/DOQI guidelines. Prognostic factors for progression to end-stage renal disease (ESRD) and all-cause mortality were analysed by using the Cox proportional hazards model.

RESULTS

Of 573 patients, 287 received MPE. Dialysis was initiated in 13.9% and 43% of the patients in the MPE and non-MPE groups, respectively (P < 0.001). The mean follow-up period was 11.7 +/- 0.9 months. The overall mortality was 1.7% and 10.1% in the MPE and non-MPE groups, respectively (P < 0.001). Cox regression analysis revealed that diabetes, estimated glomerular filtration rate (eGFR), high-sensitive C-reactive protein (hs-CRP) and MPE assignment were significant independent predictors for progression to ESRD. Independent prognostic factors for mortality included age, diabetes, eGFR, hs-CRP and MPE assignment.

CONCLUSIONS

MPE based on the NKF/DOQI guidelines may decrease the incidence of dialysis and reduce mortality in late-stage CKD patients.

Peritoneal dialysis patient selection: characteristics for success

This review focuses on the strategy of patient selection for peritoneal dialysis (PD) based on published epidemiology studies and observational data. With the success of the PD first model in Hong Kong, experience shows that there is no particular patient group that cannot be put on PD except those who have major problems in the abdomen. Incident patients should be offered the choice to receive PD at the start of dialysis in order to preserve better the residual renal function. Concern has also been expressed for a time-dependent negative impact of PD on survival, although PD in general provides survival advantage at least during the first few years after the start of dialysis. Regular patient review is essential to allow prompt adjustment of the dialysis regimen and modality when required. Accumulating research suggests that center size has a significant effect on the patient and technique survival of patients undergoing PD. Comorbid diabetes, large and small body size, peritoneal membrane transport status, elderly age group, and socioeconomic status are important patient factors to consider. Good clinical and psychosocial care of the PD patients are essential as well as the attention to their compliance. Enhanced training to medical and nursing personnel on PD is one of the key success factors for improving its utilization and outcome.

Gaining efficiencies: resources and demand for dialysis around the globe

OBJECTIVES

End-stage renal disease (ESRD) is a debilitating condition resulting in death unless treated. Treatment options are transplantation and dialysis. Alternative dialysis modalities are peritoneal dialysis (PD) and hemodialysis (HD), each of which has been shown to produce similar outcomes and survival. Nevertheless, the financial implications of each modality are different and these differences vary by country, especially in the developing world. Changes in clinically appropriate dialysis delivery leading to more efficient use of resources would increase the resources available to treat ESRD or other disabling conditions. This article outlines the relative advantages of HD and PD and uses budget impact analysis to estimate the country-specific, 5-year financial implications on total dialysis costs assuming utilization shifts from HD to PD in two high-income (UK, Singapore), three upper-middle-income (Mexico, Chile, Romania), and three lower-middle-income (Thailand, China, Colombia) countries.

RESULTS

Peritoneal dialysis is a clinically effective dialysis option that can be significantly cost-saving compared to HD, even in developing countries.

CONCLUSIONS

The magnitude of costs associated with treating ESRD patients globally is large and growing. PD is a clinically effective dialysis option that can be used by a majority of ESRD patients and can also be significantly cost-saving compared to HD therapy. Increasing clinically appropriate PD use would substantially reduce health-care costs and help health-care systems meet ever-tightening budget constraints.
