Study Description
Brief Summary:
Previous studies of the patients treated in RRI clinics suggest that hemodialysis patients undergo a certain consistent predictable pattern at the initiation of dialysis and before death. This pattern can be described as a group of patterns of patients' biological markers over a few months after starting dialysis and several months prior to death. Additional patterns can be observed that occur with changes in seasons or time of day. The aim of this study is to compare these patterns in patients treated in FMC-Asia, FMC-Europe, FMC-South America, and RRI-US populations. Noting that patterns in patient parameters are similar across continents, climates, and geographic variations only further accentuates the importance in the models that can predict patients' survival and provide an opportunity for timely intervention.

Study Design

Study Type : Observational
Actual Enrollment : 50000 participants
Observational Model: Cohort
Time Perspective: Retrospective
Official Title: International Comparison of Evolution of Clinical and Laboratory Parameters in Chronic Hemodialysis Patients
Study Start Date : January 2000
Primary Completion Date : May 2010
Study Completion Date : May 2010
Groups and Cohorts

Hemodialysis patients

Outcome Measures

Primary Outcome Measures :
  1. Date of death [ Time Frame: 10 years and 5 months ]
    The main purpose of the study is developing an alert system that will help dialysis providers recognize patients who are at increased risk of death (or hospitalization). This alert system will be developed and can be utilized in patients treated all over the world.

Secondary Outcome Measures :
  1. Hospitalizations [ Time Frame: January 2000 - May 2010 ]
