For readers familiar with the 2000-2002 (Years 1-3) Case-Mix Reports, the authors briefly describe how this report differs from the previous year’s report. First, this report seeks to evaluate the stability of many of the findings and resultant decisions from the 2000-2002 Case-Mix Reports, including the choice of case-mix adjusters, their parameterization, and their impact. Second, they have reformatted the presentation of information in a way that favors comparative tables across years were possible and which relegates older data to the Appendix when this is not possible, with the hopes of producing a more concise document.
The research described in this report was prepared for Edward Sekscenski of the Centers for Medicare & Medicaid Services by RAND Health.
