Canadian Joint Replacement Registry Metadata

Overview

The Canadian Joint Replacement Registry (CJRR) was launched in May 2001 as a voluntary registry and has now been mandated in Ontario, Manitoba and British Columbia. It was developed to provide a rich set of additional patient-level clinical, surgical and prosthesis information beyond what is captured in the Hospital Morbidity Database, the Discharge Abstract Database and the National Ambulatory Reporting System, allowing for more in-depth analysis of hip and knee replacement procedures.

Data source

Data on joint replacement procedures is received directly from

• Orthopedic surgeons
• Facilities
• Health regions
• Provincial ministries of health

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

Data coverage

CJRR contains demographic, clinical and prosthesis data from all provinces and territories except Prince Edward Island and Nunavut.*

* Currently, no procedures are performed in Nunavut.

Data availability

CJRR data is collected on a fiscal-year basis (based on surgery date), running from April 1 to March 31.

• Most recent year: fiscal year 2016–2017
• Next release: fiscal year 2017–2018 (Sept. 2018)
• 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. Diagnosis and reason for revision information are captured using drop-down categories identified by the CJRR Advisory Committee.

Data elements

As of April 1, 2012, CJRR streamlined its data elements to a new minimum data set (MDS). These are aligned with the standard set by the International Society of Arthroplasty Registers.

• 2013–2014 (MDS)
• 2012–2013 (MDS)
• 2005–2006 to 2011–2012

Prior to April 1, 2012, CJRR had a more detailed set of data elements. These included information on wait times, patient height and weight, and other information.
