Notes: *Under-reporting of incident ESKD cases from Quebec was estimated to be approximately 170 cases in 2011 and 560 cases in 2012.
^†This is an adaptation of the Charlson Index for ESRD patients; it assigns each of the 14 comorbid conditions a value of 1 to 10.
^‡Estimated glomerular filtration rate as determined by the Modification of Diet in Renal Disease (MDRD) formula (mL/min/1.73 m²).
^§Patients who first see a nephrologist less than 90 days before starting dialysis.
