Abstract

We developed a new framework for combining 17 Health Plan Employer Data and Information Set (HEDIS®) indicators into a single composite score. The resultant scale was highly reliable (coefficient alpha =0.88). A principal components analysis yielded three components to the scale: effectiveness of disease management, access to preventive and followup care, and achieving medication compliance in treating depression. This framework for reporting could improve the interpretation of HEDIS® performance data and is an important step for CMS as it moves towards a Medicare managed care (MMC) performance assessment program focused on outcomes-based measurement.
