National survey on prescription of cardiovascular drugs among outpatients with coronary artery disease in Switzerland


Muntwyler, Jörg; Noseda, Giorgio; Darioli, Roger; Gruner, Christiane; Gutzwiller, Felix; Follath, Ferenc (2003). National survey on prescription of cardiovascular drugs among outpatients with coronary artery disease in Switzerland. Swiss Medical Weekly, 133(5-6):88-92.

Abstract

BACKGROUND
Secondary prevention of coronary artery disease markedly reduces cardiovascular mortality and non-fatal endpoints. Outpatient care of subjects with coronary artery disease has been assessed in several European countries, but no current data is available for Switzerland.
METHODS
A random sample of office-based physicians across Switzerland recorded current drug prescription of outpatients with coronary artery disease in the years 2000/2001 by means of a mail questionnaire. We assessed treatment frequencies according to different patient characteristics.
RESULTS
565 patients were included (mean age 68 +/- 11 years, 75% male). There was no evidence for differences in drug utilisation among the regions. Drug prescription rates for antithrombotic agents, beta-blockers, ACE-inhibitors/angiotensin receptor blockers and lipid lowering drugs were 91%, 58%, 50% and 63% respectively. Lower treatment rates were observed among patients >70 years and in those without a history of myocardial infarction or coronary revascularisation. Forty-nine percent of the patients had a blood pressure >140/>90, and 60% had lipid readings above the intervention cut-off according to the Swiss recommendations. Among those without a history of myocardial infarction or coronary revascularisation, the respective figures were 60% and 80%.
CONCLUSIONS
Compared to former surveys evidence based drug prescription has improved in Switzerland. Despite this, therapeutic goals for cholesterol levels and blood pressure are not being reached in a large proportion of patients. A high risk group for under use of evidence based drugs are patients without a history of myocardial infarction or coronary revascularisation.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
