In response to this need, a Severity, Intensity, and Complexity (SIC) model has been developed which integrates leading severity measurement techniques with specific patient age cohorts and CC clusters to account for differences in patient intensity and complexity. The calibration and construction of the SIC model was based on a modified version of the CMS
