Clinical Risk Grouper
The Clinical Risk Grouper (CRG) of Alberta is a time series assigning each Alberta resident registered with the Alberta Health Care Insurance Plan (AHCIP) into a Clinical Risk Group (CRG).
This population-based grouper allows for clinically relevant risk adjustment, enhanced planning and innovative economic studies.

Individuals with one or more chronic conditions are classified based on those conditions or combinations of conditions, with further breakouts for condition-specific severity of illness. Individuals without a chronic condition are assigned to groups for one or more significant acute illness, or other significant health event such as delivery or newborn birth, and those without a significant acute condition, to various groups for “healthy.”
