Stakeholders had until March 29 to offer written comments to the federal government regarding revisions to the current methodology for public reporting of comparative hospital performance data. The call for comment follows a decision by the U.S. Centers for Medicare & Medicaid Services (CMS) to postpone a release of hospital performance information, which was scheduled for last summer. The delay will permit CMS to review proposed revisions to the 5-star rating methodology used to evaluate more than 4,000 acute-care hospitals across the U.S. The Hospital Compare database includes a universe of 57 measures that can be included in a data release. Among the topics CMS wants to address are potential changes to measure groupings, measure weighting, larger-than-expected shifts in performance ratings, hospital peer groupings and clustering. CMS also is seeking comment on whether public reporting should address a hospital’s year-to-year performance improvement as well as the possibility of generating customized ratings based on a user’s own performance reporting preferences. Comments should be sent to the Yale New Haven Health Services Corporation (cmsstarratings@yale.edu). Additional methodological information is available at qualitynet.org.
