Hypothesis
How have cholesterol screening and the prescription of lipid-lowering drugs changed in general practice from 1994 to 2003?
Conclusion
Cholesterol testing and treatment practices have broadened significantly, with more patients being tested and treated at lower cholesterol levels than in previous years.
Supporting Evidence
- Cholesterol testing increased in all age groups, especially for those over 65.
- 12% of patients tested were on lipid-lowering medication.
- The mean cholesterol level decreased in both treated and untreated groups.
Takeaway
Doctors are checking cholesterol levels more often and starting patients on cholesterol-lowering medications sooner than before.
Methodology
Data from the Intego database, including electronic medical records from 47 general practices, were analyzed using mixed model linear regression.
Potential Biases
The study may not fully represent all Flemish GPs due to selection based on registration quality.
Limitations
The GPs in the study were not a random sample, and there may have been unrecorded tests performed by hospital consultants.
Participant Demographics
54.56% women and 45.44% men, with a focus on patients over the age of 25.
