Implementation and pharmacoeconomic analysis of a clinical staff pharmacist practice model.
The implementation and pharmacoeconomic analysis of a clinical staff pharmacist (CSP) practice model are described. Staff pharmacists at a large, tertiary care, academic medical center were selected and trained to perform clinical pharmacy services under the direction of clinical pharmacy specialist mentors. Clinical interventions by these CSP practitioners were evaluated in terms of direct cost savings (the difference in actual acquisition costs between therapies) and cost avoidance (the dollar value of adverse drug events [ADEs] avoided). The CSPs performed a total of 4959 interventions during a 12-month period. The interventions provided direct cost savings of $92,076 and an estimated cost avoidance of $488,436. Comparing cost savings and cost avoidance with the expenses of providing these services indicated a net economic benefit of $392,660. A new model of pharmacy practice that integrates staff pharmacists into existing clinical practice has the potential to minimize the risks, decrease the costs, and improve the outcomes associated with drug therapy.
