Background: An increase in the dialysis programme expenditure is expected in most countries given the continued rise in the number of people with end-stage renal disease (ESRD) globally. Since chronic peritoneal dialysis (PD) therapy is relatively less expensive compared with haemodialysis (HD) and because there is no survival difference between PD and HD, identifying factors associated with PD use is important.
Methods: Incidence counts for the years 2003-05 were available from 36 countries worldwide.
Background And Objectives: Mortality on dialysis varies greatly worldwide, with patient-level factors explaining only a small part of this variation. The aim of this study was to examine the association of national-level macroeconomic indicators with the mortality of incident dialysis populations and explore potential explanations through renal service indicators, incidence of dialysis, and characteristics of the dialysis population.
Design, Setting, Participants, & Measurements: Aggregated unadjusted survival probabilities were obtained from 22 renal registries worldwide for patients starting dialysis in 2003-2005.
Background: Applying the Kidney Disease Outcomes Quality Initiative definitions of chronic kidney disease (CKD), it appears that CKD is common. The increased recognition of CKD has brought with it the clinical challenge of translating into practice the implications for the patient and for service planning. To understand the clinical relevance and translate that into information to support individual patient care and service planning, we explored clinical outcomes in a large British CKD cohort, identified through routine opportunistic testing, with a 6-year follow-up (≈ 13,000 patient-years).

Background: Incidence rates of renal replacement therapy (RRT) for end-stage renal disease vary considerably worldwide. This study examines the independent association between the general population, health care system and renal service characteristics and RRT incidence rates.
Methods: RRT incidence data (2003-2005) were obtained from renal registries; general population age and health and macroeconomic indices were collected from secondary sources.
Rates of initiation of renal replacement therapy (RRT), use of home modalities of treatment and patient outcomes vary considerably between countries. This paper reports the methods and baseline characteristics of countries participating in the EVEREST study (n = 46), a global collaboration examining the association between medical and non-medical factors and RRT incidence, modality mix and survival. Numbers of incident and prevalent patients were collected for current (2003-05) and historic (1983-85, 1988-90, 1993-95 and 1998-2000) periods stratified, where available, by age, gender, treatment modality and cause of end stage renal disease (diabetic versus non-diabetic).

This systematic review evaluates the benefits and harms of antimicrobial interventions for the prevention of catheter-related infections (CRIs).
Methods: MEDLINE (1950-May 2009), EMBASE (1980-May 2009) CENTRAL (up to May 2009) and bibliographies of retrieved articles were searched for relevant RCTs.
Background: A systematic review of randomized controlled trials (RCTs) comparing continuous ambulatory peritoneal dialysis (CAPD) with all forms of automated peritoneal dialysis (APD) was performed to assess their comparative clinical effectiveness.
Methods: The Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and CINAHL, were searched for relevant RCTs. Analysis was by a random effects model and results expressed as relative risk (RR) and weighted mean difference (WMD) with 95% confidence intervals (CI).
Background: Acute renal failure (ARF) is a diverse condition with no standardized definition and is managed in several sub-specialty areas within hospitals. Its incidence and aetiology are unknown and studies show a wide range of incidences. ARF is becoming more common as the population ages leading to the hypothesis that the incidence is much higher than previous estimates.

Methods: The Cochrane CENTRAL Registry, MEDLINE, EMBASE, CINAHL, the American College of Physicians Database, Database of Abstracts of Reviews of Effectiveness, and reference lists were searched for randomized trials of HF, HDF, and AFB compared with HD; HDF compared with AFB; and HF compared with HDF. Two reviewers extracted data for all-cause mortality; hypotension, headache, nausea, vomiting, and any other adverse symptoms; quality of life (QoL); hospitalization; dialysis adequacy; and end-of-treatment beta 2 -microglobulin levels.
Background: The number of patients starting renal replacement therapy (RRT) for end-stage renal disease (ESRD) in the United Kingdom rises annually. Patients are increasingly elderly with a greater prevalence of comorbid illness. Unadjusted survival, from the time of starting RRT, is not improving.

Methods: All patients commencing dialysis in nine centres in seven European countries between 1 July 1998 and 31 October 1999 were recruited.
