Study Finds Hospital Readmission and Mortality Rates Not Linked
Feb. 14—Researchers found no evidence that a hospital’s performance on 30-day mortality rates were strongly associated with performance on 30-day readmission rates, in a study in JAMA that included data on nearly 3 million hospital admissions for Medicare beneficiaries with heart attack, pneumonia, or heart failure. These findings may lessen concerns that hospitals with lower mortality rates will have higher readmission rates.
Mortality and readmission measures have been proposed for use in federal programs to modify hospital payments based on performance, the article says. And some researchers have raised concerns that these rates might have an inverse relationship, such that hospitals with lower mortality rates are more likely to have higher readmission rates.
However, the study showed correlations between risk-standardized mortality rates (RSMRs) and risk-standardized readmission rates (RSRRs) were 0.03 for acute myocardial infarction, −0.17 for heart failure, and 0.002 for pneumonia.
