Comprehensive morbidity adjustment reveals stable post-AMI mortality; challenges unadjusted rising trends and supports refined models in outcomes research.
Can changes in demographics and illness burden explain the observed rise in one-year mortality following hospitalization for AMI in Medicare patients?
The observed rise in one-year mortality following AMI in Medicare patients from 1995 to 1999 is explained by changes in patient demographics and illness burden, highlighting the importance of comprehensive risk adjustment in evaluating outcomes.
