[Failure of an educational intervention to change anticholesteremic drug prescription in primary care].
OBJECTIVE
To evaluate the effectiveness of an intervention for decreasing hypocholesterolemic drugs prescription in patients with low cardiovascular risk profile.


METHODS
Quasi-randomized intervention study.


METHODS
Public primary health care centres in the province of Valencia (Spain).


METHODS
238 general/family practitioners from 23 primary health care centres.


METHODS
The centres were assigned to either an experimental group that received the educational intervention (individual scientific information by outreach detailing and invitation to a workshop about treatment of hypercholesterolemia in the primary care setting with the participation of an opinion leader) or a control group.


RESULTS
The effectiveness of the intervention was measured through the monthly mean daily defined doses (DDD) from the 4 months prior to the intervention until 5 months thereafter. Mean DDD increased along the study period in both groups, with no detectable differences between them. Similarly, there were no between-group differences after controlling the initial prescription levels using a mixed lineal model.


CONCLUSIONS
The educational intervention as it was implemented was ineffective for changing overall hypocholesterolemic drug prescription in primary care. Consequently, this intervention is not justified for reducing pharmaceutical expenditure.
