Schizophrenia Clinical Trial
Official title:
Antipsychotic Polypharmacy: Prevalence, Background and Consequences
The primary purpose of the study is to investigate whether an intensive educational intervention can reduce the use of antipsychotic polypharmacy. It is hypothesised that the use of antipsychotic polypharmacy is, in some degree, dependent on non-patient related factors.
Several surveys have shown a high prevalence of antipsychotic polypharmacy (concomitant
prescription of at least 2 different antipsychotics) among patients with schizophrenia even
though international guidelines recommend monotherapy.
From register data areas with differences in the prevalence of antipsychotic polypharmacy
will be identified. Two high prevalence areas will be randomized to either control or
intervention area. In the intervention area an intensive educational intervention consisting
of outreach visits with a multifaceted approach will be carried out with the duration of 1
year.
Differences in health staff related factors such as knowledge and attitude towards clinical
guidelines will be assessed with a questionnaire before and after the intervention in the
intervention area as well as in the low prevalence area at baseline.
Medical records data describing the use of antipsychotic polypharmacy will be collected.
With register data health economic issues will be assessed.
