ObjectivesAlthough antipsychotic prescribing in elderly patients using polypharmacy has not been studied in well-designed clinical trials and meta-analyses, there is an urgent need to monitor prescribing practice in this population. One of the possible approaches to optimize pharmacotherapy may be the involvement of clinical pharmacists (CPs). The aim of this research was to examine whether the involvement of a CP can improve treatment guidelines adherence and change the total number of medications per patient in older patients who are treated with excessive polypharmacy that includes antipsychotics.MethodsThis cohort retrospective study included older patients (65 years or older) treated with at least one antipsychotic and excessive polypharmacy (10 or more medications concurrently) between 2012 and 2014 in primary care. The main outcome measures were antipsychotic treatment guidelines’ adherence and the total number of medications per patient after the CP’s interventions. Only interventions including antipsychotics were studied in detail (i.e., discontinuation, switching, initiation, dose adjustment, change of another medication because of a drug-related problem). Data on diagnoses, patient pharmacotherapy and the CP’s interventions were obtained from clinical records and medical reviews.

The acceptance of the CP’s recommendations, but not age, improved antipsychotic treatment guidelines’ adherence (p = 0.041).ConclusionsThese results show that a collaborative care approach including a CP in primary care significantly improved the adherence to treatment guidelines. The results also support the implementation of this service in the Slovenian healthcare system, although more studies are needed.
