This bulletin outlines the facility-testing process for the Canadian Joint Replacement Registry (CJRR) for 2017–2018. In order to facilitate the submission process and enhance data quality, all participating facilities are required to provide annual test data to the Canadian Institute for Health Information (CIHI) in advance of live submissions to most CIHI databases. Facility testing occurs once a facility’s licensed vendor has successfully submitted test data. Facilities are also required to submit data for retesting when there is a change in vendor.
