Collection and usage attributes
|Guide for use:|
Measurement in mmol/L to 1 decimal place.
Record the absolute result of the total cholesterol measurement. When reporting, record whether or not the measurement of Cholesterol-total - measured was performed in a fasting specimen.
When reporting, record absolute result of the most recent Cholesterol-total - measured in the last 12 months to the nearest 0.1 mmol/L.
Measurement of lipid levels should be carried out by laboratories, or practices, which have been accredited to perform these tests by the National Association of Testing Authorities.
In settings where the monitoring of a person's health is ongoing and where a measure can change over time (such as general practice), the Service contact—service contact date, DDMMYYYY should be recorded.
High blood cholesterol is a key factor in heart, stroke and vascular disease, especially coronary heart disease.
Poor nutrition can be a contributing factor to heart, stroke and vascular disease as a population's level of saturated fat intake is the prime determinant of its level of blood cholesterol.
Large clinical trials have shown that people at highest risk of cardiovascular events (e.g. pre-existing ischaemic heart disease) will derive the greatest benefit from lipid lowering drugs. Recent trials have suggested that there should be no cholesterol level threshold for the initiation of treatment in this group of patients. In October 2006, the PBS criteria for lipid-lowering drugs was expanded to include all patients identified as high-risk (based on PBS criteria) regardless of their cholesterol level.
