Incidence of End-Stage Kidney Disease (ESKD), by Primary Diagnosis

This indicator gives the breakdown, by primary diagnosis, of all patients with end-stage kidney disease (ESKD) who began renal replacement therapy (RRT) for the first time in the calendar year.

Increasing incidence rates over time have important implications for resources, disease management and the need for kidney donation.

Calculation

Counts and rates are based on patients registered during a given calendar year in a Canadian facility. Patients who began RRT for ESKD outside of Canada but are subsequently treated in Canada are included in prevalence counts but not incidence counts.

Short/Other Names

Description

Breakdown by primary diagnosis of all incident patients (new patients) with end-stage kidney disease who began renal replacement therapy (RRT) (either dialysis or renal transplantation) for the first time in the calendar year

Rationale

Disease etiology can be tracked by viewing changes in the primary diagnosis over time. There are significant costs associated with treating this patient group.

Interpretation

Increasing incidence rates over time have important implications for resources, disease management and the need for kidney donation.

Caveats and Limitations

The indicator is based on voluntary data submitted to CORR from facilities across Canada. Submission of data for patients beginning RRT for ESKD is not mandatory.

Data from Quebec was not included because of significant under-reporting between 2011 and 2019, which may lead to biased results.

Trending Issues

An overview of under-reporting of incident ESKD cases can be found in Data Quality Documentation for Users: Canadian Organ Replacement Register, 2010 to 2019 Data (PDF).
