Abstract
Worldwide the assistance on renal replacement therapy (RRT) is carried out mainly by private for-profit services and in a market with increase in mergers and acquisitions. The aim of this study was to conduct an integrative systematic review on privatization and oligopolies in the RRT sector in the context of contemporary capitalism. The inclusion criteria were scientific articles without language restrictions and that addressed the themes of oligopoly or privatization of RRT market. Studies published before 1990 were excluded. The exploratory search for publications was carried out on February 13, 2024 on the Virtual Health Library Regional Portal (VHL). Using the step-by-step of PRISMA flowchart, 34 articles were retrieved, of which 31 addressed the RRT sector in the United States and 26 compared for-profit dialysis units or those belonging to large organizations with non-profit or public ones. The main effects of privatization and oligopolies, evaluated by the studies, were: mortality, hospitalization, use of peritoneal dialysis and registration for kidney transplantation. When considering these outcomes, 19 (73%) articles showed worse results in private units or those belonging to large organizations, six (23%) studies were in favor of privatization or oligopolies and one study was neutral (4%). In summary, most of the articles included in this systematic review showed deleterious effects of oligopolization and privatization of the RRT sector on the patients served. Possible explanations for this result could be the presence of conflicts of interest in the RRT sector and the lack of incentive to implement the chronic kidney disease care line. The predominance of articles from a single nation may suggest that few countries have transparent mechanisms to monitor the quality of care and outcomes of patients on chronic dialysis.

Effect of Dialysis Modalities on All-Cause Mortality and Cardiovascular Mortality in End-Stage Kidney Disease: A Taiwan Renal Registry Data System (TWRDS) 2005-2012 Study. J Pers Med 2022; 12:jpm12101715. [PMID: 36294854 PMCID: PMC9605117 DOI: 10.3390/jpm12101715] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Revised: 10/03/2022] [Accepted: 10/06/2022] [Indexed: 12/12/2022] Open
Abstract
Introduction: End-stage kidney disease (ESKD) patients who need renal replacement therapy need to face a dialysis modality decision: the choice between hemodialysis (HD) and peritoneal dialysis (PD). Although the global differences in HD/PD penetration are affected by health-care policies, these two modalities may exert different effects on survival in patients with ESKD. Although Taiwan did not implicate PD as first policy, we still need to compare patients’ outcomes using two modalities in a nation-wise database to determine future patients’ care and health policies. Methods: We used the nationwide Taiwan Renal Registry Data System (TWRDS) database from 2005 to 2012 and included 52,900 patients (48,371 on HD and 4529 on PD) to determine all-cause and cardiovascular mortality among ESKD patients. Results: Age-matched survival probability from all-cause mortality was significantly lower in patients on PD than in those on HD (p < 0.05). The adjusted hazard ratios of 3-year and 5-year all-cause and cardiovascular mortality were significantly higher in PD compared with HD. The presence of comorbid conditions including myocardial infarction, coronary artery disease (CAD), diabetes mellitus (DM), hypoalbuminemia, hyperferritinemia and hypophosphatemia was related with significantly higher all-cause and CV mortality in PD patients. No significant difference was noted among younger patients <45 years of age regardless of DM and/or comorbid conditions. Conclusion: Although PD did not have the survival advantage compared to HD in all dialysis populations, PD was related with superior survival in younger non-DM patients, regardless of the presence of comorbidities. Similarly, for younger ESKD patients without the risk of CV disease, both PD and HD would be suitable dialysis modalities.

Abstract
BACKGROUND Access to forms of dialysis, kidney transplantation (Tx) and comprehensive conservative management (CCM) for patients with end-stage kidney disease (ESKD) varies across European countries. Attitudes of nephrologists, information provision and decision-making may influence this access and nephrologists may experience several barriers when providing treatments for ESKD. METHODS We surveyed European nephrologists and kidney transplant surgeons treating adults with ESKD about factors influencing modality choice. Descriptive statistics were used to compare the opinions of professionals from European countries with low-, middle- and high-gross domestic product purchasing power parity (GDP PPP). RESULTS In total, 681 professionals from 33 European countries participated. Respondents from all GDP categories indicated that ∼10% of patients received no information before the start of renal replacement therapy (RRT) (P = 0.106). Early information provision and more involvement of patients in decision-making were more frequently reported in middle- and high-GDP countries (P < 0.05). Professionals' attitudes towards several treatments became more positive with increasing GDP (P < 0.05). Uptake of in-centre haemodialysis was sufficient to 73% of respondents, but many wanted increased uptake of home dialysis, Tx and CCM. Respondents experienced different barriers according to availability of specific treatments in their centre. The occurrence of barriers (financial, staff shortage, lack of space/supplies and patient related) decreased with increasing GDP (P < 0.05). CONCLUSIONS Differences in factors influencing modality choice when providing RRT or CCM to adults with ESKD were found among low-, middle- and high-GDP countries in Europe. Therefore a unique pan-European policy to improve access to treatments may be inefficient. Different policies for clusters of countries could be more useful.

Abstract
BACKGROUND Employment is important for the quality of life and financial security of patients of working age receiving kidney replacement therapy (KRT). We aimed to examine self-reported work status and general, physical and mental work ability, and to determine associations between demographic, disease-related, work-related, and macro-economic factors and employment. . METHODS Europeans from 37 countries, aged 19-65 years, treated with dialysis or kidney transplantation, filled out the web-based or paper-based cross-sectional EDITH kidney patient survey between November 2017 and January 2019. We performed descriptive analyses and multivariable generalized logistic mixed models. RESULTS Of the 3 544 patients, 36.5% were employed and working (25.8% of dialysis patients, 53.9% of kidney transplant recipients [KTRs]). Mean general work ability was 5.5 out of 10 (dialysis: 4.8, KTRs: 6.5). Non-working patients (all: 4.1, dialysis: 3.9, KTRs: 4.7) scored lower than working patients (all: 7.7, dialysis 7.3, KTRs: 8.0). Working dialysis patients scored lower on physical and mental work ability (7.1 and 8.1) than working KTRs (8.0 and 8.4, p < 0.001). Impaired physical work ability (42.7%) was more prevalent than impaired mental work ability (26.7%). Male sex, age 40-49 years, higher education, home dialysis or kidney transplantation as current treatment, treatment history including kidney transplantation, absence of diabetes mellitus, better general work ability, and higher country GDP were positively associated with employment (p < 0.05). CONCLUSIONS Low employment rates and impaired work ability were prevalent among European patients receiving KRT. Demographic, disease-related, work-related, and macro-economic factors were associated with employment.

Abstract
Background Accurate comparisons of haemodialysis (HD) and peritoneal dialysis (PD) survival based on observational studies are difficult due to substantial residual confounding that arises from imbalances between treatments. Propensity score matching (PSM) comparisons confer additional advantages over conventional methods of adjustment by further reducing selection bias between treatments. We conducted a systematic review of studies that compared mortality between in-centre HD with PD using a PSM-based approach. Methods A sensitive search strategy identified all citations in the PubMed, Cochrane and EMBASE databases from inception through November 2018. Pooled PD versus HD mortality hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated through random-effects meta-analysis. A subsequent meta-regression explored factors to account for between-study variation. Results The systematic review yielded 214 citations with 17 cohort studies and 113 578 PSM incident dialysis patients. Cohort periods spanned the period 1993–2014. The pooled HR for PD versus HD was 1.06 (95% CI 0.99–1.14). There was considerable variation by country, however, mortality risks for PD versus HD remained virtually unchanged when stratified by geographical region with HRs of 1.04 (95% CI 0.94–1.15), 1.14 (95% CI 0.99–1.32) and 0.98 (0.87–1.10) for European, Asian and American cohorts, respectively. Subgroup meta-analyses revealed similar risks for patients with diabetes [HR 1.09 (95% CI 0.98–1.21)] and without diabetes [HR 0.99 (95% CI 0.90–1.09)]. Heterogeneity was substantial (I2 = 87%) and was largely accounted for by differences in cohort period, study type and country of origin. Together these factors explained a substantial degree of between-studies variance (R2 = 90.6%). Conclusions This meta-analysis suggests that PD and in-centre HD carry equivalent survival benefits. Reported differences in survival between treatments largely reflect a combination of factors that are unrelated to clinical efficacy.

Abstract
Background Access to various kidney replacement therapy (KRT) modalities for patients with end-stage kidney disease differs substantially within Europe. Methods European adults on KRT filled out an online or paper-based survey about factors influencing and experiences with modality choice (e.g. information provision, decision-making and reasons for choice) between November 2017 and January 2019. We compared countries with low, middle and high gross domestic product (GDP). Results In total, 7820 patients [mean age 59 years, 56% male, 63% on centre haemodialysis (CHD)] from 38 countries participated. Twenty-five percent had received no information on the different modalities, and only 23% received information >12 months before KRT initiation. Patients were not informed about home haemodialysis (HHD) (42%) and comprehensive conservative management (33%). Besides nephrologists, nurses more frequently provided information in high-GDP countries, whereas physicians other than nephrologists did so in low-GDP countries. Patients from low-GDP countries reported later information provision, less information about other modalities than CHD and lower satisfaction with information. The majority of modality decisions were made involving both patient and nephrologist. Patients reported subjective (e.g. quality of life and fears) and objective reasons (e.g. costs and availability of treatments) for modality choice. Patients had good experiences with all modalities, but experiences were better for HHD and kidney transplantation and in middle- and high-GDP countries. Conclusion Our results suggest European differences in patient-reported factors influencing KRT modality choice, possibly caused by disparities in availability of KRT modalities, different healthcare systems and varying patient preferences. Availability of home dialysis and kidney transplantation should be optimized.

Abstract
Background The strong geographic variations in the incidence rates of renal replacement therapy (RRT) for end-stage renal disease are not solely related to variations in the population's needs, such as the prevalence of diabetes or the deprivation level. Inequitable geographic access to health services has been involved in different countries but never in France, a country with a generous supply of health services and where the effect of the variability of medical practices was highlighted in an analysis conducted at the geographic scale of districts. Our ecological study, performed at the finer scale of townships in a French area of 8,370,616 inhabitants, investigated the association between RRT incidence rates, socioeconomic environment and geographic accessibility to healthcare while adjusting for morbidity level and medical practice patterns. Methods Using data from the Renal Epidemiology and Information Network registry, we estimated age-adjusted RRT incidence rates during 2010–2014 for the 282 townships of the area. A hierarchical Bayesian Poisson model was used to examine the association between incidence rates and 18 contextual variables describing population health status, socioeconomic level and health services characteristics. Relative risks (RRs) and 95% credible intervals (95% CrIs) for each variable were estimated for a 1-SD increase in incidence rate. Results During 2010–2014, 6,835 new patients ≥18 years old (4231 men, 2604 women) living in the study area started RRT; the RRT incidence rates by townships ranged from 21 to 499 per million inhabitants. In multivariate analysis, rates were related to the prevalence of diabetes [RR (95% CrI): 1.05 (1.04–1.11)], the median estimated glomerular filtration rate at dialysis initiation [1.14 (1.08–1.20)], and the proportion of incident patients ≥ 85 years old [1.08 (1.03–1.14)]. After adjusting for these factors, rates in townships increased with increasing French deprivation index [1.05 (1.01–1.08)] and decreased with increasing mean travel time to reach the closest nephrologist [0.92 (0.89–0.95]). Conclusion These data confirm the influence of deprivation level, the prevalence of diabetes and medical practices on RRT incidence rates across a large French area. For the first time, an association was found with the distance to nephrology services. These data suggest possible inequitable geographic access to RRT within the French health system.

A call for harmonization of European kidney care: dialysis reimbursement and distribution of kidney replacement therapies. Nephrol Dial Transplant 2020; 35:979-986.

Abstract
Abstract
Background
We compare reimbursement for haemodialysis (HD) and peritoneal dialysis (PD) in European countries to assess the impact on government healthcare budgets. We discuss strategies to reduce costs by promoting sustainable dialysis and kidney transplantation.
Methods
This was a cross-sectional survey among nephrologists conducted online July–December 2016. European countries were categorized by tertiles of gross domestic product per capita (GDP). Reimbursement data were matched to kidney replacement therapy (KRT) data.
Results
The prevalence per million population of patients being treated with long-term dialysis was not significantly different across tertiles of GDP (P = 0.22). The percentage of PD increased with GDP across tertiles (4.9, 8.2, 13.4%; P < 0.001). The HD-to-PD reimbursement ratio was higher in countries with the highest tertile of GDP (0.7, 1.0 versus 1.7; P = 0.007). Home HD was mainly reimbursed in countries with the highest tertile of GDP (15, 15 versus 69%; P = 0.005). The percentage of public health expenditure for reimbursement of dialysis decreased across tertiles of GDP (3.3, 1.5, 0.7%; P < 0.001). Transplantation as a proportion of all KRT increased across tertiles of GDP (18.5, 39.5, 56.0%; P < 0.001).
Conclusions
In Europe, dialysis has a disproportionately high impact on public health expenditure, especially in countries with a lower GDP. In these countries, the cost difference between PD and HD is smaller, and home dialysis and transplantation are less frequently provided than in countries with a higher GDP. In-depth evaluation and analysis of influential economic and political measures are needed to steer optimized reimbursement strategies for KRT.

Abstract
Background Home-based dialysis, including peritoneal dialysis (PD) and home hemodialysis (HHD), has been shown to be associated with lower costs and higher health-related quality of life than in-center HD. However, factors influencing the choice of dialysis modality, including gender, are still not well understood. Methods A questionnaire was sent out to all dialysis patients in the western region of Sweden in order to investigate factors affecting choice of dialysis modality. Logistic regression was used to analyze the data. Results Patients were more likely to have home dialysis if they received predialysis information from 3 or more sources and, to a greater extent, perceived the information as comprehensive and of high quality. In addition, patients had a lower likelihood of receiving home dialysis with increasing age and if they lived closer to a dialysis center. Men had in comparison with women a greater likelihood of receiving home dialysis if they lived with a spouse. In-center dialysis patients more often believed that the social interaction and support provided through in-center HD treatment influenced the choice of dialysis modality. Conclusion This study highlights the need for increased awareness of various factors that influence the choice of dialysis modality and the importance of giving repeated, comprehensive, high-quality information to dialysis and predialysis patients and their relatives. Information and support must be adapted to the needs of individual patients and their relatives if the intention is to improve patients’ well-being and the proportion of patients using home dialysis.

Dialysis initiation, modality choice, access, and prescription: conclusions from a Kidney Disease: Improving Global Outcomes (KDIGO) Controversies Conference. Kidney Int 2019; 96:37-47.

Abstract
Globally, the number of patients undergoing maintenance dialysis is increasing, yet throughout the world there is significant variability in the practice of initiating dialysis. Factors such as availability of resources, reasons for starting dialysis, timing of dialysis initiation, patient education and preparedness, dialysis modality and access, as well as varied "country-specific" factors significantly affect patient experiences and outcomes. As the burden of end-stage kidney disease (ESKD) has increased globally, there has also been a growing recognition of the importance of patient involvement in determining the goals of care and decisions regarding treatment. In January 2018, KDIGO (Kidney Disease: Improving Global Outcomes) convened a Controversies Conference focused on dialysis initiation, including modality choice, access, and prescription. Here we present a summary of the conference discussions, including identified knowledge gaps, areas of controversy, and priorities for research. A major novel theme represented during the conference was the need to move away from a "one-size-fits-all" approach to dialysis and provide more individualized care that incorporates patient goals and preferences while still maintaining best practices for quality and safety. Identifying and including patient-centered goals that can be validated as quality indicators in the context of diverse health care systems to achieve equity of outcomes will require alignment of goals and incentives between patients, providers, regulators, and payers that will vary across health care jurisdictions.

Abstract
In many countries, the use of peritoneal dialysis (PD) remains low despite arguments that support its greater use, including dialysis treatment away from hospital settings, avoidance of central venous catheters, and potential health economic advantages. Training patients to manage aspects of their own care has the potential to enhance health literacy and increase patient involvement, independence, quality of life, and cost-effectiveness of care. Complex reasons underlie the variable use of PD across the world, acting at the level of the patient, the health care team that is responsible for them, and the health care system that they find themselves in. Important among these is the availability of competitively priced dialysis fluid. A number of key interventions can affect the uptake of PD. These include high-quality patient education around dialysis modality choice, timely and successful catheter placement, satisfactory patient training, and continued support that is tailored for specific needs, for example, when people present late requiring dialysis. Several health system changes have been shown to increase PD use, such as targeted funding, PD First initiatives, or physician-inserted PD catheters. This review explores the factors that explain the considerable international variation in the use of PD and presents interventions that can potentially affect them.

Abstract
BACKGROUND/AIMS Since comorbidities are major determinants of modality choice, and also interact with dialysis modality on mortality outcomes, we examined the pattern of modality choice according to comorbidities and then evaluated how such choices affected mortality in incident dialysis patients. METHODS We analyzed 32,280 incident dialysis patients in Korea. Patterns in initial dialysis choice were assessed by multivariate logistic regression analyses. Multivariate Poisson regression analyses were performed to evaluate the effects of interactions between comorbidities and dialysis modality on mortality and to quantify these interactions using the synergy factor. RESULTS Prior histories of myocardial infarction (p = 0.031), diabetes (p = 0.001), and congestive heart failure (p = 0.003) were independent factors favoring the initiation with peritoneal dialysis (PD), but were associated with increased mortality with PD. In contrast, a history of cerebrovascular disease and 1-year increase in age favored initiation with hemodialysis (HD) and were related to a survival benefit with HD (p < 0.001, both). While favoring initiation with HD, having Medical Aid (p = 0.001) and male gender (p = 0.047) were related to increased mortality with HD. Furthermore, although the severity of comorbidities did not inf luence dialysis modality choice, mortality in incident PD patients was significantly higher compared to that in HD patients as the severity of comorbidities increased (p for trend < 0.001). CONCLUSIONS Some comorbidities exerted independent effects on initial choice of dialysis modality, but this choice did not always lead to the best results. Further analyses of the pattern of choosing dialysis modality according to baseline comorbid conditions and related consequent mortality outcomes are needed.

Abstract
The treatment of chronic kidney disease (CKD) and of end-stage renal disease (ESRD) imposes substantial societal costs. Expenditure is highest for renal replacement therapy (RRT), especially in-hospital haemodialysis. Redirection towards less expensive forms of RRT (peritoneal dialysis, home haemodialysis) or kidney transplantation should decrease financial pressure. However, costs for CKD are not limited to RRT, but also include nonrenal health-care costs, costs not related to health care, and costs for patients with CKD who are not yet receiving RRT. Even if patients with CKD or ESRD could be given the least expensive therapies, costs would decrease only marginally. We therefore propose a consistent and sustainable approach focusing on prevention. Before a preventive strategy is favoured, however, authorities should carefully analyse the cost to benefit ratio of each strategy. Primary prevention of CKD is more important than secondary prevention, as many other related chronic diseases, such as diabetes mellitus, hypertension, cardiovascular disease, liver disease, cancer, and pulmonary disorders could also be prevented. Primary prevention largely consists of lifestyle changes that will reduce global societal costs and, more importantly, result in a healthy, active, and long-lived population. Nephrologists need to collaborate closely with other sectors and governments, to reach these aims.

Abstract
Catheter-related infections in peritoneal dialysis (PD) remain a significant complication, and some patients with recurrent exit-site (ESI) and/or tunnel infections may experience external cuff extrusion. In these cases, cuff-shaving has been described as a possible course of treatment. During a 4-year period, there were 44 patients with PD at our department; all received double-cuffed Tenckhoff catheters. Six (13%) never started on PD. Five (13%) of the 38 active PD patients experienced cuff extrusion. Causes of end-stage renal disease (ESRD) were diabetic nephropathy (n = 1), toxic nephropathy (n = 1), hypertensive nephrosclerosis (n = 1), systemic disease (n = 1) and one with unknown cause. PD catheters were inserted by the Department of Surgery and our patients waited a mean of 3.71 weeks (0.57–7.86) from catheter insertion to PD start. Patients were followed up by monthly and even fortnightly during infections. Our cohort experienced two (1–5) ESIs per patient prior to cuff extrusion. Cultures showed growth of Staphylococcus aureus and the patients received dicloxacillin orally 500 mg qid for 3–4 weeks. Of the 38 active PD patients, 5 (13%) developed cuff extrusion with an incidence of 0.20 episodes/patient/year, manifesting on average at 32 weeks (17.3–40.6), due to repeated ESI in four patients and substantial weight loss in one patient. All five underwent cuff-shaving and the ESIs resolved completely in 80% of the cases assisted by supplemental treatment with mupirocin and/or dicloxacillin. There were no complications to the cuff-shaving procedure itself. None of the five patients experienced new ESIs after cuff-shaving had been performed. Cuff-shaving reduces the rate of recurring ESIs. The procedure is safe, if performed correctly, and poses no risk to the patient or the catheter.

Abstract
Most of the global burden of chronic kidney disease (CKD) is occurring in low- and middle-income countries (LMICs). As a result of rapid urbanization in LMICs, a growing number of populations are exposed to numerous environmental toxins, high infectious disease burdens and increasing rates of noncommunicable diseases. For CKD, this portends a high prevalence related to numerous etiologies, and it presents unique challenges. A better understanding of the epidemiology of CKD in LMICs is urgently needed, but this must be coupled with strong public advocacy and broad, collaborative public health efforts that address environmental, communicable, and non-communicable risk factors.

Abstract
BACKGROUND Whether the choice of dialysis modality in patients with end stage renal disease may impact mortality is undecided. No randomized controlled trial has properly addressed this issue. Propensity-matched observational studies could give important insight into the independent effect of peritoneal (PD) opposed to haemodialysis (HD) on all-cause and cardiovascular mortality. METHODS To correct for case-mix differences between patients treated with PD and HD, propensity-matched analyses were utilized in all patients who initiated dialysis as first renal replacement therapy in Norway in the period 2005-2012. PD patients were matched in a 1:1 fashion with HD patients, creating 692 pairs of patients with comparable baseline variables. As-treated and intention-to treat analyses were undertaken to assess cardiovascular and all-cause mortality. Interaction analyses were used to assess differences in the relationship between initial dialysis modality and mortality, between strata of age, gender and prevalent diabetes mellitus. RESULTS In the as-treated analyses, initial dialysis modality did not impact 2-year (PD vs. HD: HR 0.87, 95 % CI 0.67-1.12) or 5-year all-cause mortality (HR 0.95, 95 % CI 0.77-1.17). In patients younger than 65 years, PD was superior compared to HD with regard to both 2-year (HR 0.39, 95 % CI 0.19-0.81), and 5-year all-cause mortality (HR 0.49, 95 % CI 0.27-0.89). Cardiovascular mortality was also lower in the younger patients treated with PD (5-year HR 0.38, 95 % CI 0.15-0.96). PD was not associated with impaired prognosis in any of the prespecified subgroups compared to HD. The results were similar in the as-treated and intention-to-treat analyses. CONCLUSION Survival in PD was not inferior to HD in any subgroup of patients even after five years of follow-up. In patients below 65 years, PD yielded superior survival rates compared to HD. Increased use of PD as initial dialysis modality in ESRD patients could be encouraged.

Abstract
BACKGROUND Peritoneal dialysis (PD) for the treatment of end-stage renal failure was introduced in the 1960s. Nowadays it has evolved to an established therapy that is complementary to hemodialysis (HD), representing 11% of all patients treated worldwide with dialysis. Despite good clinical outcomes and similar results in patient survival between PD and HD, the penetration of PD is decreasing in the Western world. SUMMARY First the major events in the history of the development of PD are described. Then important insights into the physiology of peritoneal transport are discussed and linked to the changes in time observed in biopsies of the peritoneal membrane. Furthermore, the developments in peritoneal access, more biocompatible dialysate solutions, automated PD at home, the establishment of parameters for dialysis adequacy and strategies to prevent infectious complications are mentioned. Finally non-medical issues responsible for the declining penetration in the Western world are analyzed. KEY MESSAGES Only after introduction of the concept of continuous ambulatory PD by Moncrief and Popovich has this treatment evolved in time to a renal replacement therapy. Of all structures present in the peritoneal membrane, the capillary endothelium offers the rate-limiting hindrance for solute and water transport for the diffusive and convective transport of solutes and osmosis. The functional and anatomical changes in the peritoneal membrane in time can be monitored by the peritoneal equilibrium test. Peritonitis incidence decreased by introduction of the Y-set and prophylaxis using mupirocin on the exit site. The decrease in the proportion of patients treated with PD in the Western world can be explained by non-medical issues such as inadequate predialysis patient education, physician experience and training, ease of HD initiation, overcapacity of in-center HD, lack of adequate infrastructure for PD treatment, costs and reimbursement issues of the treatment. FACTS FROM EAST AND WEST (1) PD is cheaper than HD and provides a better quality of life worldwide, but its prevalence is significantly lower than that of HD in all countries, with the exception of Hong Kong. Allowing reimbursement of PD but not HD has permitted to increase the use of PD over HD in many Asian countries like Hong Kong, Vietnam, Taiwan, Thailand, as well as in New Zealand and Australia over the last years. In the Western world, however, HD is still promoted, and the proportion of patients treated with PD decreases. Japan remains an exception in Asia where PD penetration is very low. Lack of adequate education of practitioners and information of patients might as well be reasons for the low penetration of PD in both the East and West. (2) Patient survival of PD varies between and within countries but is globally similar to HD. (3) Peritonitis remains the main cause of morbidity in PD patients. South Asian countries face specific issues such as high tuberculosis and mycobacterial infections, which are rare in developed Asian and Western countries. The infection rate is affected by climatic and socio-economic factors and is higher in hot, humid and rural areas. (4) Nevertheless, the promotion of a PD-first policy might be beneficial particularly for remote populations in emerging countries where the end-stage renal disease rate is increasing dramatically.

Abstract
BACKGROUND Although previous studies suggest similar patient survival for peritoneal dialysis (PD) and haemodialysis (HD), PD use has decreased worldwide. We aimed to study trends in the choice of first dialysis modality and relate these to variation in patient and technique survival and kidney transplant rates in Europe over the last 20 years. METHODS We used data from 196 076 patients within the European Renal Association-European Dialysis and Transplant Association (ERA-EDTA) Registry who started renal replacement therapy (RRT) between 1993 and 2012. Trends in the incidence rate and prevalence on Day 91 after commencing RRT were quantified with Joinpoint regression. Crude and adjusted hazard ratios (HRs) for 5-year dialysis patient and technique survival were calculated using Cox regression. Analyses were repeated using propensity score matching to control for confounding by indication. RESULTS PD prevalence dropped since 2007 and HD prevalence stabilized since 2009. Incidence rates of PD and HD decreased from 2000 and 2009, respectively, while the incidence of kidney transplantation increased from 1993 onwards. Similar 5-year patient survival for PD versus HD patients was found in 1993-97 [adjusted HR: 1.02, 95% confidence interval (95% CI): 0.98-1.06], while survival was higher for PD patients in 2003-07 (HR: 0.91, 95% CI: 0.88-0.95). Both PD (HR: 0.95, 95% CI: 0.91-1.00) and HD technique survival (HR: 0.93, 95% CI: 0.87-0.99) improved in 2003-07 compared with 1993-97. CONCLUSIONS Although initiating RRT on PD was associated with favourable patient survival when compared with starting on HD treatment, PD was often not selected as initial dialysis modality. Over time, we observed a significant decline in PD use and a stabilization in HD use. These observations were explained by the lower incidence rate of PD and HD and the increase in pre-emptive transplantation.

Abstract
INTRODUCTION End-stage renal disease (ESRD) is a major public health problem with increasing prevalence and costs. An understanding of the long-term trends in dialysis rates and outcomes can help inform health policy. We determined the optimal case definition for the diagnosis of ESRD using administrative claims data in the province of Manitoba over a 7-year period. METHODS We determined the sensitivity, specificity, predictive value and overall accuracy of 4 administrative case definitions for the diagnosis of ESRD requiring chronic dialysis over different time horizons from Jan. 1, 2004, to Mar. 31, 2011. The Manitoba Renal Program Database served as the gold standard for confirming dialysis status. RESULTS During the study period, 2562 patients were registered as recipients of chronic dialysis in the Manitoba Renal Program Database. Over a 1-year period (2010), the optimal case definition was any 2 claims for outpatient dialysis, and it was 74.6% sensitive (95% confidence interval [CI] 72.3%-76.9%) and 94.4% specific (95% CI 93.6%-95.2%) for the diagnosis of ESRD. In contrast, a case definition of at least 2 claims for dialysis treatment more than 90 days apart was 64.8% sensitive (95% CI 62.2%-67.3%) and 97.1% specific (95% CI 96.5%-97.7%). Extending the period to 5 years greatly improved sensitivity for all case definitions, with minimal change to specificity; for example, for the optimal case definition of any 2 claims for dialysis treatment, sensitivity increased to 86.0% (95% CI 84.7%-87.4%) at 5 years. CONCLUSION Accurate case definitions for the diagnosis of ESRD requiring dialysis can be derived from administrative claims data. The optimal definition required any 2 claims for outpatient dialysis. Extending the claims period to 5 years greatly improved sensitivity with minimal effects on specificity for all case definitions.

Abstract
In 1964 the ERA-EDTA Registry was started as one of the first renal registries in
the world. This meeting report describes how this European registry has
developed over the 50 years of its existence. Where the first report presented
patient numbers, nowadays the Registry acts as a platform for collaborative
renal research in Europe. In addition, it provides training in epidemiology
methods to nephrologists and other renal researchers.

Abstract
Background: The number of patients receiving renal replacement therapy (RRT) increases annually and worldwide. Differences in the RRT incidence, prevalence, and modality vary between regions and countries for reasons yet to be clarified. Aims: Gain a better understanding of the association between hemodialysis (HD)-related variables and general population global health indicators. Methods: The present study included prevalent HD patients from 27 countries/regions from the monitoring dialysis outcomes (MONDO) database from 2006-2011. Global population health indicators were obtained from the 2014 World Health Organization report and the Human Development Index from the Human Development Report Office 2014. The Spearman rank test was used to assess the correlations between population social economic indicators and HD variables. Results: A total of 84,796 prevalent HD patients were included. Their mean age was 63 (country mean 52-71), and 60% were males (country mean 52-85%). Significant correlations were found between HD demographic clusters and population education, wealth, mortality, and health indicators. The cluster of nutrition and inflammation variables were also highly correlated with population mortality, wealth, and health indicators. Finally, cardiovascular, fluid management, and dialysis adequacy clusters were associated with education, wealth, and health care resource indicators. Conclusion: We identified socioeconomic indicators that were correlated with dialysis variables. This hypothesis-generating study may be helpful in the analysis of how global health indicators may interfere with access to HD, treatment provision, dialytic treatment characteristics, and outcomes.

Abstract
Geographic remoteness has been found to influence health-related outcomes negatively. As reported in the literature, rural dialysis patients have a higher risk of mortality with increasing travel distance to dialysis units. However, few studies have focused on the impact of travel distances on the development of dialysis complications. We utilized a prospectively collected chronic hemodialysis patient cohort from a rural regional hospital for analysis. Data on demographics, comorbidities, and serum laboratory results were obtained. Correlation analyses between travel distance to dialysis units and dialysis complications were conducted, and significantly correlated parameters were entered into multivariate logistic regression models to determine their exact associations. A total of 46 rural chronic hemodialysis patients were enrolled, with an average age higher than others in the literature. Significant correlation was found between travel distance and serum hemoglobin levels (R(2) = -0.34, P value = 0.029). Multivariate logistic regression found that every 1 km increase in travel distance was associated with an increased risk of anemia (hemoglobin <9 g/dL) (odds ratio 1.46; P value = 0.01). Sensitivity analyses further showed that the associated risk was partially attenuated by serum albumin (odds ratio 1.83; P value = 0.07) and ferritin (odds ratio 1.39; P value = 0.08) levels. This is the first study to demonstrate the association between increased travel distance to dialysis units and the risk of anemia in chronic dialysis patients, especially elderly. Malnutrition, inflammation, and atherosclerosis syndrome could be partially responsible for the observed association. Further research is required to confirm our findings.

A missed opportunity - consequences of unknown levetiracepam pharmacokinetics in a peritoneal dialysis patient. BMC Nephrol 2014; 15:49. [PMID: 24739070 PMCID: PMC4006077 DOI: 10.1186/1471-2369-15-49] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2013] [Accepted: 01/20/2014] [Indexed: 11/23/2022] Open
Abstract
Background Levetiracetam is a frequently used drug in the therapy of partial onset, myoclonic and generalized tonic-clonic seizures. The main route of elimination is via the kidneys, which eliminate 66% of the unchanged drug as well as 24% as inactive metabolite that stems from enzymatic hydrolysis. Therefore dose adjustments are needed in patients with chronic kidney disease stage 5 D, i.e. patients undergoing dialysis treatment. In this patient population a dose reduction by 50% is recommended, so that patients receive 250–750 mg every 12 hours. However “dialysis” can be performed in using different modalities and treatment intensities. For most of the drugs pharmacokinetic data and dosing recommendations for patients undergoing peritoneal dialysis are not available. This is the first report on levetiracetam pharmacokinetics in a peritoneal dialysis patient. Case presentation A 73-y-old Caucasian male (height: 160 cm, weight 93 kg, BMI 36.3 kg/m2) was admitted with a Glasgow Coma Scale of 10. Due to diabetic and hypertensive nephropathy he was undergoing peritoneal dialysis for two years. Eight weeks prior he was put on levetiracetam 500 mg twice daily for suspected partial seizures with secondary generalization. According to the patient’s wife, levetiracetam lead to fatigue and somnolence leading to trauma with fracture of the metatarsal bone. Indeed, even 24 hours after discontinuation of levetiracetam blood level was still 29.8 mg/l (therapeutic range: 12 – 46 mg/l). Fatigue and stupor had disappeared five days after discontinuation of the levetiracepam. A single dose pharamockinetic after re-exposure showed an increased half life of 18.4 hours (normal half life 7 hours) and levetiracetam content in the peritoneal dialysate. Both half-life and dialysate content might help to guide dosing in this patient population. Conclusion If levetiracetam is used in peritoneal dialysis patients it should be regularly monitored to avoid supratherapeutic levels that could lead to severe sequelae.

Abstract
Background: Chronic kidney disease (CKD) is a worldwide public health problem with increasing incidence and prevalence and associated expenses. Objectives: To explore different perceptions of rural and urban patients with chronic kidney disease (CKD) about kidney transplant. Patients and Methods: We conducted four focus groups, each including 5 or 6 patients with stage 5 CKD or end stage renal disease living in a rural or urban area. Open-ended questions probed patient familiarity with kidney transplant, perceptions of benefits of kidney transplant, perceived barriers to kidney transplant, and views about living donation. All the sessions were recorded and professionally transcribed. Responses were pooled, de-identified, and analyzed using qualitative thematic content analysis. Results: Urban patients were more likely to receive supplementary information and being strongly encouraged by their nephrologists to seek transplant. All participants acknowledged “independence” as the main advantage of transplantation. Increased freedom to travel and improved life expectancy were mentioned only among the urban groups. The main themes in all groups regarding perceived barriers to transplant were the tedious pre-transplant testing and workup expenses. Among rural groups, there was a perception that distance from transplant centers impedes transplant evaluation. Religious reasons favoring and opposing transplant were mentioned by participants in a rural group. Some members contended that since illness is God’s will, we should not change it. Others in the same group argued that “God is not ready for us to give up”. Praise and gratitude for the living donor were expressed in all groups, but concerns about donor’s outcome were discussed only within the rural groups. In discussing preference about known or anonymous donors, members of an urban group mentioned favoring an anonymous donor, citing unease with a sense of life-long indebtedness. Conclusions: Observed differences in perceptions among rural and urban patients about aspects of transplant may contribute to geographic disparities in transplant. The findings could be helpful to guide future individualized, culturally sensitive educational interventions about transplant for patients with CKD.

Abstract
BACKGROUND The treatment of chronic kidney disease through dialysis is a considerable expense in most health systems. The two chief methods of providing dialysis, haemodialysis (HD) and peritoneal dialysis (PD) have significant differences in cost composition and factors of production. The aim of this article is to identify and quantify the macroeconomic variables that influence the relative cost of such modalities across different countries. METHODS From previously published literature, we extracted the estimates of HD/PD cost ratios in a total of 46 countries. We conducted a multivariate regression analysis using the estimated HD/PD cost ratio in each country, with several country level indicators as explanatory variables. We found a strong statistical effect of the following variables on the HD/PD cost ratio: country's level of development, economies of scale and percentage of private health-care expenditure. RESULTS The statistical effects on HD/PD ratio by local manufacturing and relaxed import regulation of PD equipment were calculated and were found to be very significant. CONCLUSIONS it is possible for a country to still reap the benefits of economies of scale in provision of PD, even in the absence of a large enough market to make local production of PD equipment feasible in that country.

Abstract
The marked variation that exists in renal replacement therapy (RRT) epidemiology between countries and within countries requires careful systematic examination if the root causes are to be understood. While individual patient-level studies are undoubtedly important, there is a complementary role for more population-level, area-based studies--an aetiological approach. The EVEREST Study adopted such an approach, bringing RRT incidence rates, survival and modality mix together with macroeconomic factors, general population factors and renal service organizational factors for up to 46 countries. This review considers the background to EVEREST, its key results and then the main methodological lessons and their potential application to ongoing work.
