Comparative Effectiveness of New Approaches to Improve Mortality Risk Models From Medicare Claims Data.

ABSTRACT:

Importance

Risk adjustment models using claims-based data are central in evaluating health care performance. Although US Centers for Medicare & Medicaid Services (CMS) models apply well-vetted statistical approaches, recent changes in the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) coding system and advances in computational capabilities may provide an opportunity for enhancement.

Objective

To examine whether changes using already available data would enhance risk models and yield greater discrimination in hospital-level performance measures.

Design, setting, and participants

This comparative effectiveness study used ICD-9-CM codes from all Medicare fee-for-service beneficiary claims for hospitalizations for acute myocard
