Reporting Methods
Publicly reported at national and provincial/territory level as part of national Continuing Care Reporting System (CCRS), quarterly. Also includes reporting at region, LTCF, corporation, and sector level (not public). The CCRS quality indicators use 4 rolling quarters of data for calculations in order to have a sufficient number of assessments for risk adjustment. Since residents are assessed on a quarterly basis, each resident can contribute to the indicator up to 4 times.
