Measure Methodology Reports
The methodology and updates reports listed below describe the methods used to develop the risk-standardized readmission measures, and the 2016 updates and quality assurance activities.
Additional rationale of CMS’s methodological decisions during development and reevaluation of the readmission measures is available in the Frequently Asked Questions document.
2016 Readmission Measures Updates
CMS contracted with a team of clinical and statistical experts from Yale New Haven Health Services Corporation/Center for Outcomes Research and Evaluation (YNHHSC/CORE) to develop, and annually re-evaluate and update the readmission measures. The 2016 reports describe the measures' re-evaluation activities conducted in preparation for the 2016 public reporting cycle.
