The table below shows the weight applied to each measure group. Application of clustering algorithm to categorize summary scores into star ratingsįor each hospital, a hospital summary score is calculated by taking the weighted average of the hospital’s scores for each measure group.Assignment of hospitals to peer groups based on their number of measure groups (3, 4, or 5).Application of minimum thresholds for receiving an Overall Star Rating.Calculation of hospital summary scores as a weighted average of available group scores.Calculation and standardization of measure group scores.Selection and standardization of measures for inclusion in the Overall Star Rating.Overall Star Ratings are created using this seven-step process: The methodology used to calculate Overall Star Ratings involves multiple steps to select, standardize, and calculate scores based on Care Compare measures. Most hospitals will have an Overall Hospital Quality Star Rating of 3. Overall Star Ratings aren’t calculated for Veterans Health Administration (VHA) or Department of Defense (DoD) hospitals. Hospitals report data to The Centers for Medicare & Medicaid Services ("CMS") through the Hospital Inpatient Quality Reporting (IQR) Program, Hospital Outpatient Quality Reporting (OQR) Program, Hospital Readmission Reduction Program (HRRP), Hospital-Acquired Condition (HAC) Reduction Program, and Hospital Value-Based Purchasing (VBP) Program. Once reporting thresholds are met, a hospital’s Overall Star Rating is calculated using only those measures for which data are available. The Overall Hospital Quality Star Rating for ASCENSION ST MICHAELS HOSPITAL summarizes a variety of measures across 5 areas of quality into a single star rating for each hospital.
