Quality of secondary cardiovascular prevention in specialised care in the Netherlands: the SOLID study.

OBJECTIVE
To determine the extent to which Dutch patients with a history of cardiovascular disease and high cholesterol levels, treated in specialised care, are achieving low-cholesterol targets as defined by national guidelines.


DESIGN
Hospital-based cohort study.


SETTING
Practices of 41 hospital-based cardiologists and internists in the Netherlands.


SUBJECTS
7377 patients.


RESULTS
Forty-one percent of the patients with an indication for secondary cardiovascular prevention by lipid-lowering drug treatment were receiving medication and were achieving cholesterol targets, 42% were receiving lipid-lowering medication but had cholesterol levels above target, 11% were not receiving treatment, and 5% had no recent lipid measurements.


CONCLUSION
Compared with previous studies, the SOLID study shows that a relatively large percentage of the Dutch patients under specialised care with a history of cardiovascular disease and an indication for cholesterol-reducing therapy are currently being treated. A considerable proportion of the patients, however, are still not receiving optimal treatment and more than 10% are not being treated at all.
