Proposed Methods for Developing and Testing Risk- and Reliability-Adjustment Models for HCBS Composite Measures

This methods report describes Mathematica Policy Research’s approach to creating risk-adjustment models using composite measures to profile care delivered to the home- and community-based service (HCBS) population. The composite measures are adaptations of the Agency for Healthcare Research and Quality’s prevention quality indicators (PQIs), which measure hospital admissions for ambulatory care–sensitive conditions.
