Using admission characteristics to predict short-term mortality from myocardial infarction in elderly patients: results from the Cooperative Cardiovascular Project
Article Abstract:
Only a small percentage of the variation in mortality rates between hospitals can be explained by the clinical status of the patient upon admission. Researchers used data from the Cooperative Cardiovascular Project (CCP) to develop a model to predict which patients would die within 30 days of a heart attack. This information could be used to compare the quality of care between different hospitals. The CCP studied 30-day mortality rates in 14,581 patients hospitalized in over 100 hospitals in four states for acute heart attack. The 30-day mortality rate was 21% overall, but varied from 18.1% to 22.6% depending on the state. Clinical factors at admission most associated with variations in 30-day mortality were age, average arterial pressure, respiratory rate and blood urea nitrogen. However, these could only account for 27% of the variation. Some of the variation could be a result of the state where the patient was hospitalized, but this still left 67% of the variation unexplained.

Regionalization and the underuse of angiography in the Veterans Affairs health care system as compared with a fee-for-service system
Article Abstract:
The underuse of needed angiography after acute myocardial infarction in a traditional Medicare fee-for-service system is compared with underuse in the regionalized Department of Veterans Affairs (VA) health care system. It is found that there is underuse of needed angiography after acute myocardial infarction in both the VA and Medicare systems, but the rate of underuse is significantly higher in the VA.

Outcome of myocardial infarction in Veterans Health Administration patients as compared with Medicare patients
Article Abstract:
The care provided in VA hospitals is probably as good as the care provided in other hospitals. This was the conclusion of a study of 2,486 veterans and 29,249 Medicare beneficiaries who were treated in a hospital for heart attack. Although the veterans had more co-existing diseases, 30-day and one-year mortality rates were similar.
