Abstract

Abstract: Background: Concurrent prescription of more than one type of antipsychotic for the same patient – antipsychotic polypharmacy (APP) – is associated with increased incidence of side effects, uncertain therapeutic benefit and general guidelines advise against it. Nevertheless, APP is common and there is little evidence about possible interventions to improve practice. Aims: To investigate the prevalence and documentation quality of APP in specialized psychiatric care and assess the feasibility and effect of a simple intervention to improve clinical practice. Methods: We examined the prevalence and the quality of documentation of APP in medical records from a large inpatient treatment department before and 6 months after an intervention, which consisted of giving feedback to doctors on their prescription practices as well as teaching about current guidelines. Prescription and documentation before and after intervention were compared between intervention and control wards. Results: One hundred and twenty-one medical records were examined at baseline. 43% of these had APP, of these 27% was satisfactory documented. After the intervention, the proportion with APP was reduced from 42% to 29% in the intervention group. There was a statistically significant interaction effect of the intervention group and the after-intervention condition on this reduction. The percentage with satisfactory documentation of APP was increased after the intervention in both groups, but we found no corresponding interaction effect. Conclusion: APP is prevalent in inpatient treatment of patients with mainly psychotic disorders but documentation of this is insufficient. Simple education and feedback on prescription and records documentation practices may increase adherence to guidelines.
