Resource Utilization Groups version III Plus Grouping Methodology: Flowcharts, SAS Code and CMI Values  Core

The Resource Utilization Groups version III Plus (RUG-III Plus) methodology is used in the Continuing Care Reporting System (CCRS). It assigns continuing care assessments to Resource Utilization Groups using RAI-MDS 2.0 assessment data and appropriate Case Mix Index (CMI) values. CIHI has released specifications for the RUG-III Plus case-mix system to licensed CCRS vendors, for use by organizations that are interested in implementing it. If interested, please work with your vendor to ensure the new methodology is incorporated into your systems.

Please note that the RUG-III Plus grouping methodology and weights for 2018-2019 are the most up-to-date versions.

The price you pay for an item depends on the type of organization to which you belong. Until you sign in, we do not know which price applies to you.

No. Regardless of the language in which the publication itself is available, the series screen provides a general description of the publications in that series and, for each edition, gives you the option of choosing the language and the media type (for example, paper or PDF) of the publication that you want. CIHI often publishes reports in both English and French, though there is sometimes a delay between the publication of the English version and the availablility of the French version. The series information will always be available in both English and French, even if the report itself is only available in one language.

If you want the downloadable version of an available publication and the price is free, as is often the case, you can simply download the file (usually a PDF) by clicking the Download link.
