Canadian Organ Replacement Register (CORR) metadata

Overview

The Canadian Organ Replacement Register (CORR) is a national database that provides statistics to track long-term trends for

• Dialysis activity
• Organ transplantation
• Organ donation
• Wait list statistics

Find out more about organ transplants, organ donations and dialysis, including reports and analyses based on CORR data.

Data source

CORR collects data from dialysis centres, transplant centres, organ donation organizations and provincial programs in Canada.

The data is collected and reported on a calendar-year basis (January 1 to December 31). This is consistent with the practice in other international registries that report on end-stage organ failure.

As a result, international comparison reporting is possible.

Data coverage

Patients are tracked from their first treatment (dialysis or transplantation) to the date of death, unless they are lost to follow-up.

Only treatments provided in Canada are included in CORR reports. CORR also captures data about patients transferred outside of Canada when those facilities report the transfers. This makes it possible to record continuity of care.

Information on organ donors is linked to information about those who receive the organ transplant.

Data availability

• Most recent year: 2023
• Next release: 2024 (September 2025)
• Historical series: 1981 to 2022
• By request: 1981 to 2023 (please complete a data inquiry form)

Classification

CORR uses a custom coding system for diagnoses. This system was adapted from other renal registries and is based on input from the CORR advisory board.

The system allows detailed clinical information relevant to chronic organ failure to be captured and analyzed.

These coding systems match those used in various European dialysis/transplant registries to help facilitate international comparisons.

Data elements

Data elements are collected for the following:

• Patient-specific treatment and outcome data on end-stage kidney failure patients receiving renal replacement therapy in Canada, including
