Advanced-scope pharmacist roles in medical outpatient clinics: a cost-consequence analysis

Abstract

Background: There is a growing body of evidence that supports the clinical effectiveness of pharmacist roles in outpatient settings. However, limited studies have investigated the economic efficiency of advanced-scope outpatient pharmacist roles, particularly in the Australian setting. Assessing the overall costs and benefits of these outpatient pharmacist roles is needed to ensure service sustainability.

Aims: To use a cost-consequence approach to evaluate the advanced-scope outpatient pharmacist roles across multiple clinic disciplines from the hospital perspective.

Methods: A cost-consequence analysis was undertaken using data from a previous clinical-effectiveness study. All outpatient pharmacist consults conducted from 1 June 2019 to 31 May 2020 across 18 clinic disciplines were evaluated. Consequences from the pharmacist services included number of consults conducted, number of medication-related activities and number of resolved recommendations.

Results: The overall cost to the hospital for the outpatient pharmacist service across all clinics was AU$1 991 122, with a potential remuneration of AU$3 895 247. There were 10 059 pharmacist consults undertaken for the 12-month period. Medication-related activities performed by pharmacists primarily included 6438 counselling and education activities and 4307 medication list activities. When the specialist pharmacist roles were added to the outpatient clinics, several health service benefits were also realised.

Conclusions: The addition of pharmacist roles to outpatient clinics can increase the cost of services; however, they also can increase medication optimisation activities. Future research should examine a societal perspective that includes broader cost and effectiveness outcomes. This study could justify the implementation of advanced-scope outpatient pharmacist roles in other Australian hospitals.
