What was measured?What percentage of HMO members had their cholesterol level checked after a heart attack or other serious heart problem or surgery?
These results are based on a sample of HMO patient administrative and medical records.
Why is it important?Persons with heart disease should have their cholesterol levels tested regularly as a step to avoid a repeat heart attack, a stroke or death.
Look for differences of at least four percentage points.
Smaller differences are often not significant.
