Brief Summary:
This study will follow 2500 prevalent Chronic Kidney Disease (CKD) patients with Glomerular Filtration Rate (GFR) from 15-45 ml/min for 30 months with serial measurements every 6 months and subsequent annual chart review up to 60 months. This observational study will analyze the demographics, clinical status, medications and blood and urine samples of these patients and study the conventional biochemical, hormonal and metabolic parameters assessing which underlying biomarkers reflect the processes involved with disease progression.

Bioimpedance sub-study cohort
Funded by a grant from Kidney Foundation of Canada, Dr. Catherine Clase initiated a bioimpedance sub-study across 7 centres and recruited n=416 within the CANPREDDICT population. The study uses bioimpedance measurements to assess volume status to determine the multivariable relationship between baseline volume overload and subsequent cardiovascular events. Subjects are followed at 6 months intervals for 2 years.
Ethnic enrichment cohort
Additional recruitment initiated and funded by the Principal Investigator, Adeera Levin for enriching the ethnic representation within the Canadian cohort on South Asian and Oriental Asian was completed from Sept 2012 to June 2013, n=53.
Original CanPreddict cohort
The original CanPreddict cohort was recruited from Jun 2008 - Oct 2009 has 2544 CKD patients across Canada.

Primary Outcome Measures :
  1. Renal Replacement Therapy [ Time Frame: 6 monthly for 3 years, annually up to 5 years ]
    Renal Replacement Therapy is defined as dialysis start or transplantation.

  2. Cardiovascular events [ Time Frame: 6 monthly for 3 years, annually up to 5 years ]
    Cardiovascular events are defined as myocardial infarction, ischemic and hemorrhagic stroke, coronary revascularization, congestive heart failure, peripheral bypass and gangrenes, adjudicated by a nephrologist, cardiologist and neurologist.

  3. Death [ Time Frame: 6 monthly for 3 years, annually up to 5 years ]
    Deaths are reported with source documentation and adjudicated for ischemic or congestive cardiovascular death, other cardiovascular death, non-cardiovascular death and unknown cause of death.
