Measure Methodology Reports
The publicly reported 30-day risk-standardized readmission measures include:
- Acute Myocardial Infarction (AMI)
- Chronic Obstructive Pulmonary Disease (COPD)
- Heart Failure (HF)
- Hospital-Wide All-Cause Unplanned Readmission (HWR)
- Total Hip Arthroplasty (THA) and/or Total Knee Arthroplasty (TKA)
The technical reports listed below describe the methods used in the development of the risk-standardized readmission measures and the subsequent annual measure updates and quality assurance activities. More detailed justifications of CMS’s methodological choices in the development and maintenance of the readmission measures are available in the Frequently Asked Questions (FAQs) document posted on the Resources page.
2014 Readmission Measures Maintenance
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 review and update the readmission measures annually. The 2014 reports describe the measures maintenance activities conducted in preparation for the 2014 public reporting cycle.
