Overview

The Canadian Joint Replacement Registry (CJRR) was launched in May 2001 as a voluntary registry and has now been mandated in several provinces. CJRR collects patient-specific information (clinical, surgical and prosthesis) on hip and knee replacement surgeries performed in Canada.

This metadata page primarily covers CJRR data collected via CJRR systems: the legacy CJRR electronic file system, the CJRR web tool (retired in 2018) and the CJRR paper forms (retired in 2013). As of 2018–2019, CJRR data can be submitted via the Discharge Abstract Database (DAD) under Group 20. Refer to the DAD metadata page for details about the DAD.

Data source

Data on joint replacement procedures is received directly from

  • Facilities
  • Health regions
  • Provincial ministries of health

Currently, CJRR reporting is mandatory in Nova Scotia, Ontario, Manitoba and British Columbia. Participation is voluntary in the other provinces and territories.

Beginning in 2018–2019, CJRR data will be sourced from the CJRR electronic file system and from the DAD Group 20 information. Data source differs by jurisdiction.

Data coverage

As data sources for CJRR differ by jurisdiction as of 2018–2019, email cjrr@cihi.ca for the latest information.

Data availability

CJRR data is based on surgery date and collected by fiscal year (April 1 to March 31).

  • Most recent year: fiscal year 2017–2018
  • Next release: fiscal year 2018–2019 (August 2019)
  • Historical series: fiscal years 2001–2002 to 2016–2017

Data from 2003–2004 onward is available for custom data requests. Please complete a data request form.

Classification

No official classification standards are used in the capture of CJRR data (outside of the DAD). Diagnosis and reason for revision are captured using drop-down categories identified by the CJRR Advisory Committee, with consideration given to the categories used by international orthopedic registries.

Data elements

CJRR data elements collect patient information, surgical information and prosthesis (implant) information. As of April 1, 2012, the data elements were streamlined to a new minimum data set (MDS). These are aligned with the standard set by the International Society of Arthroplasty Registers.
