Gaining valid answers to so-called sensitive questions is an age-old problem in survey research. Various techniques have been developed to guarantee anonymity and minimize the respondent’s feelings of jeopardy. Two such techniques are the randomized response technique (RRT) and the unmatched count technique (UCT). In this study we evaluate the effectiveness of different implementations of the R...

BACKGROUND Chronic kidney disease (CKD) is common, important and associated with increased healthcare needs due to CKD progression. Definitions of renal disease progression are multiple, and not always comparable. A measure of 'progression' directly comparable with renal replacement therapy (RRT) initiation would identify 'progressors' in research and for healthcare planning. METHODS The Gram...

BACKGROUND The Danish National Registry on Regular Dialysis and Transplantation (NRDT) provides systematic information on the epidemiology and treatment of end-stage chronic kidney disease in Denmark. It is therefore of major importance that the registry is valid and complete. The aim of the present study was to evaluate the registration of incident patients on chronic renal replacement therapy...

INTRODUCTION Indications for renal replacement therapy (RRT) have not been generally standardized and vary among intensive care units (ICUs). We aimed to assess the proportion, indications, and modality of RRT, as well as the association between the proportion of RRT use and 90-day mortality in patients with septic shock in Finnish adult ICUs. METHODS We identified patients with septic shock ...

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 macr...

We read with interest the article published by Zou et al. [1] regarding the timing of renal replacement therapy (RRT) initiation in patients with acute kidney injury (AKI) post-cardiac surgery. The authors claim that their meta-analysis shows that early RRT initiation decreases 28-day mortality in this context. This meta-analysis included a mix of observational (retrospective and prospective) s...

INTRODUCTION These analyses examine (a) survival from the start of renal replacement therapy (RRT), based on the total incident UK RRT population reported to the UK Renal Registry, including the 18% who started on PD and the 6% who received a pre-emptive transplant and (b) survival of prevalent patients. Changes in survival between 1997 and 2008 are also reported. METHODS Survival was calcula...

Rapidly-exploring Random Tree Star(RRT*) is a recently proposed extension of Rapidly-exploring Random Tree (RRT) algorithm that provides a collisionfree, asymptotically optimal path regardless of obstacles geometry in a given environment. However, one of the limitation in the RRT* algorithm is slow convergence to optimal path solution. As a result it consumes high memory as well as time due to ...

Whether or not to provide RRT, and when to start, are two of the fundamental questions facing nephrologists and intensive-care practitioners in most cases of severe AKI. In recent publications, the timing of initiation of RRT was listed as one of the top priorities in research on AKI. However, this dimension has not been included as a factor in any of the large RCTs in this area. The optimal ti...
