The Evaluation Method

Test and control areas were chosen for the intervention matched for population size and socio-economic characteristics, GP, and pharmacist numbers. The initiative took place over 3 years: 1995 pre-intervention, 1996 the intervention year, 1997 post-intervention.

The campaign was evaluated in two ways: by questionnaires distributed before and after the campaign and by quantitative analysis of prescription and sales of target medicines before and after the campaign, in both the test and the control areas.

Agreement was obtained from the health authorities and their medical and pharmaceutical advisors for the circulation of pre- and post-campaign questionnaires to GPs and community pharmacists in both the test and the control areas. In addition, agreement was obtained for access to "prescribing analysis and cost" (PACT) data for GPs in both areas.
