Background
Bipolar disorder and schizophrenia are severe mental illnesses, each with a prevalence of approximately 1–2% in the general population. There is considerable controversy about differentiating schizophrenia from schizoaffective or bipolar disorder owing to many similarities in psychopathology, progression, and biological factors. The aim of this study was to identify similarities and differences in the pharmacological treatment of these disorders by comparing the prescription patterns.
Method
In this retrospective, explorative study we analyzed the prescribed medication of 300 patients with bipolar, schizophrenic, or schizoaffective disorders from data obtained from ten German adult psychiatric clinics of the LWL (“Landschaftsverband Westfalen-Lippe”) psychiatric network.
Results
Only 21.8% of patients analyzed were consistently compliant in taking their medication before hospitalization. Polypharmacy was applied in 75.6% of cases, whereby 2.27 psychopharmacological agents were prescribed at discharge. Briefly, we observed greater similarity between prescription patterns associated with bipolar and schizoaffective disorders than with schizophrenia prescription patterns.
Conclusion
Polypharmacy tends to be more the rule than the exception, especially when patients present with affective psychotic features. Bipolar and schizoaffective disorders cannot be differentiated according to their prescription patterns.
