Glossary Definition

Definition:

A refined version of the Diagnosis Related Group (DRG™) case-mix system that classifies cases into levels of severity and complexity based on the presence of comorbidities and complications and their impact on resource use.

This system has been used by the Manitoba Centre for Health Policy in earlier case-mix costing work (Finlayson et al., 2009). For more information see section 1 - Case-Mix Costing Using RDRGs in the [/b]Hospital Costing in the 1990's[/b] concept.
