BACKGROUND: Quetiapine is an antipsychotic that is widely prescribed off-label by family physicians despite evidence that safer alternatives exist. The aim of this research was to explore, in-depth, family physicians' reasons for this behaviour.
METHODS: We conducted qualitative interviews with 15 urban family physicians in Alberta between October 2015 and April 2016. Participants were purposively selected based on sex, years of experience and practice type. Interviews explored participants' experiences prescribing quetiapine. Interviews were recorded, transcribed verbatim and coded with the use of thematic analysis.
RESULTS: A wish to support day-to-day function of patients with complex psychosocial needs without causing benzodiazepine addiction motivated participants to prescribe quetiapine. The indications were varied and included incomplete symptom resolution, unclear or multiple mental health diagnoses, and complicated psychosocial problems. Family physicians benchmarked their prescribing against peers and were reluctant to stop medication started by colleagues. Limited knowledge of quetiapine's adverse effects led prescribers to choose low dosages.
INTERPRETATION: Quetiapine helped family physicians treat patients with complex mental health problems without prescribing benzodiazepines, but awareness of quetiapine's adverse effects was poor. Education about quetiapine should combine psychopharmacology with multidisciplinary educational initiatives that focus on symptom resolution, comorbidity and nondrug options to promote more appropriate prescribing.
