Abstract

Background: Evidence on the effectiveness of educational interventions on prescribing behaviour modification in prevention of cardiovascular disease is still insufficient. We evaluated the effects of a brief educational intervention on prescription of hydroxymethylglutaryl-CoA reductase inhibitors (statins), inhibitors of platelet aggregation (IPA), and antihypertensive agents (AH). Design: Cluster randomised controlled trial with continuous medical education (CME) groups of general practitioners (GPs). Methods: Prescription of statins, IPA, and AH were verified prior to study start (BL), immediately after index consultation (IC), and at follow-up after 6 months (FU). Prescription in patients at high risk (>15% risk of a cardiovascular event in 10 years, based on the Framingham equation) and no prescription in low-risk patients (≤ 15%) were considered appropriate. Results: An intervention effect on prescribing could only be found for IPA. Generally, changes in prescription over time were all directed towards higher prescription rates and persisted to FU, independent of risk status and group allocation. Conclusions: The active implementation of a brief evidence-based educational intervention on global risk in CVD did not lead directly to risk-adjusted changes in prescription. Investigations on an extended time scale would capture whether decision support of this kind would improve prescribing risk-adjusted sustainably.

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.
