The Rehabilitation Patient Group (RPG) grouping methodology classifies rehabilitation inpatients into discrete groups based on clinical information submitted to CIHI’s National Rehabilitation Reporting System (NRS).
Overview of the methodology
The RPG grouping methodology is applied to episodes based on a client’s primary reason for receiving inpatient rehabilitation services, client age at admission, and motor and cognitive functional status. When a client is discharged, their episode is weighted based on their length of stay, RPG and associated Rehabilitation Cost Weights (RCWs).

Methodology in action
NRS-weighted episodes are used to produce RPG resource utilization reports. CIHI produces these reports to summarize clinical and resource characteristics of individuals and facilities. A variety of audiences may use weighted RPG reports, including financial and decision-support analysts, facility administrators and management teams in health regions and ministries of health.
Weighted RPG reports for the NRS are available in the following reporting tool (login required):
