While CMS provides hospitals with an “Excess Readmission Ratio” in their Hospital Specific Reports, which is the number of predicted readmissions, divided by the number of expected readmissions, Medisolv provides clients with the number of readmissions that would have to be avoided to avoid a financial penalty. This proprietary calculation is based on the number of observed unplanned 30-day readmissions minus expected readmissions. Estimated Excess Readmissions are calculated both prospectively for future payment years, and retrospectively for final-result years. The prediction of unplanned 30-day readmissions is based on predictive modeling techniques developed by Medisolv, which consider an individual hospital’s historical index case volume, expected, and predicted readmissions. Each quarter, every hospital’s performance is recomputed, using one of thousands of machine learning models until a best-fit is achieved for a given measure and for a given hospital.
