Glossary Definition

Last Updated: 2009-04-09

Definition:

Resource Intensity Weights (RIW™) are the relative case weights for CMGs™ used to measure the intensity of resource use (relative cost) associated with different diagnostic, surgical procedure and demographic characteristics of an individual. RIWs™ are assigned according to the case mix group to which an individual is assigned as well as their age, health status, and discharge status and are based upon micro-costing. In this report, we have used RIWs™ assigned using the CMG with Complexity Overlay (CMG Plx™) methodology.
