Pharmacists in clozapine clinics improving physical health monitoring

Abstract

Introduction: People living with schizophrenia have a higher rate of comorbid physical health diseases and compared with the general population die earlier due to these diseases. A pharmacist working in an outpatient mental health clinic setting could assist with the management of physical health disease for this population. The aim of this study was to investigate whether having a pharmacist in a community clozapine clinic would improve adherence to physical health monitoring and whether this would have a positive effect on these physical health outcomes.

Methods: This retrospective observational study compared patient data from 2 clozapine clinics; one where a pharmacist engaged in medication reviews and management of medication side effects, and another that did not have a pharmacist. The rates of physical health monitoring and the changes from baseline of physical health outcomes (weight, BMI, BP, HbA1c, and lipids) were compared after the first pharmacist intervention (medication review).

Results: The pharmacist clinic had statistically higher rates of metabolic and ECG monitoring (glucose 48% vs 11%, P < .001; lipids 61% vs 7.1%, P < .001; ECG 15% vs 0%, P = .001). Positive trends in weight were identified in the pharmacist-group, although this failed to reach statistical significance.

Discussion: This study shows that pharmacists providing regular medication reviews improves physical health monitoring for patients receiving clozapine.
