Study objectivesTwo hypotheses:
1. Dissemination of locally and multidisciplinairy developed guidelines can lead to a modest but relevant change of volumes of prescriptions in the desired direction
2. What is the additional effect on change of volumes of prescriptions because of involving the target group in the preparation and development of the guidelines
Ethics approval(s)Not provided at time of registration
Health condition(s) or problem(s) studiedImproving rational prescribing behaviour among GPs in the Netherlands
InterventionThe randomised intervention concerns the intensified involvement of GPs in the development procedure of a set of prescription guidelines. A randomised subgroup of GPs were invited for a more intense role and received conceptual guidelines to comment on them. The other GPs only received the final version of the prescription guidelines. The second design of our study, the quasi experiment, concerns the dissemination of locally and multidisciplinary guidelines in the south of the Netherlands, controlled by a comparable region elsewhere in the Netherlands. The guidelines contained 14 recommendations on antibiotics, asthma/COPD drugs and cholesterol drugs.
Intervention typeOther
Primary outcome measurePrescription data, gathered retrospectively per GP per month during the period 2001-2004. Expected directions of change have been defined based on the detailed recommendations contained in the guidelines, in combination with estimates based on the expertise of the initially involved key regional representatives.
Secondary outcome measuresDrug volumes and pre/post changes between groups on short-term and long term (one and two years after).
