Reducing the prescribing of antibiotics in general practices through outreach visits.: A randomised controlled trial in southern Denmark
(English)Manuscript (preprint) (Other academic)
Aims: To study the effects of outreach visits and a simple desk guide on the prescribing in general practice of all antibacterial agents intended for systemic use (ATC code J01), broad spectrum penicillins (J01CA), pivmecillinam (J01CA08), and macrolids (J01FA), and betalaktamase sensitive penicillin (J01CE) to expected to be unchanged or increase.
Study population: Eighty-eight out of 94 general practices in the former Storstrøm County, that agreed to participate, were randomly allocated into two parallel study arms, an intervention and a control area.
Method: The year 1999 was used as the run-in-period, 2000 as the intervention period, and the spring of 2001 as the post-trial period. All participating practices received an outreach visit during the intervention period, and focus in the intervention area was on the prescribing of antibacterial agents. Data on practice characteristics and on prescribing level for the six drug groups was obtained from the County Health Insurance database. Multiple linear regression analysis was used to evaluate differences in prescribing trends across the study period.
Results: After adjustments for differences in initial prescribing levels practices in the intervention area prescribed less of all antibacterial agents intended for systemic use and less broad spectrum penicillin than practices in the control area. For the other drug groups under study, pivmecillinam, betalaktamase sensitive penicillins and macrolids, there were non-significant trends in the intended direction.
Conclusions: Outreach visits and a simple desk guide appear to affect the prescribing of antibacterial agents as intended.
