Sound Inpatient Physicians Inc. retained Milliman to develop benchmarks for various inpatient metrics, both at the nationwide and regional level. This report presents the methodology of our analysis. We developed benchmarks for both the commercial and Medicare populations for the following metrics:

• Inpatient admission rate after an intense Emergency Department (ED) visit
• Medical and surgical inpatient readmission rates
• Inpatient discharge rates to the various medical venues

This report was commissioned by Sound Physicians.
