Use of an Innovative Pharmaceutical Class Scoring Tool for Prioritized Annual Formulary Review.

Though The Joint Commission requires health systems perform annual formulary review, guidance for how to perform this review is lacking. Published methods include comprehensive review of all pharmaceutical classes; however, this approach may not be the most efficient or effective option for a health system with a large formulary. To create a prioritization system for annual formulary review through development of a pharmaceutical class scoring tool. Drug information pharmacists developed the scoring tool, which used external and internal data to score pharmaceutical classes in 4 categories: safety, efficacy, cost, and utilization. The primary outcome, number of formulary changes resulting from pharmaceutical class review, was compared between the highest-scoring and lowest-scoring class to assess the tool's ability to prioritize high-yield class reviews. The tool calculated scores for 91 pharmaceutical classes, altogether containing 962 medications. After review of the highest-scoring class, corticosteroids, 2 formulary changes were made: one dosage form was removed from formulary, and one medication was restricted to outpatient use only. Zero formulary changes resulted from review of the lowest-scoring class, pharmaceutical adjuvants. The tool described in this study prioritized annual formulary review efforts by identifying a pharmaceutical class with meaningful formulary optimization opportunities as the highest-scoring class, while correctly identifying a class with no optimization opportunities as the lowest-scoring class.
