Measuring the Relative Contribution of Social Risk Factors in an Enhanced Risk‐Adjustment Model for Unplanned Hospital Readmissions

摘要

Recent research provides evidence that social risk factors should be accounted for when measuring hospital performance. Since 2015, the Massachusetts Center for Health Information and Analysis (CHIA) has publicly reported on all‐payer, unplanned hospital readmissions using an adapted version of the Yale/CMS hospital‐wide readmission measure. According to expert recommendations of a statewide workgroup, CHIA expanded its existing risk‐adjustment model to incorporate patient‐ and community‐level social risk factors. This study aims to establish a method to measure the relative contributions of social risk factors in the enhanced risk‐adjustment model for unplanned hospital readmissions.
