Computer-based support system for formulary decisions

Area of Science:

• Health Informatics
• Pharmacoeconomics
• Decision Science

Background:

• Pharmacy and Therapeutics (P&T) committees play a crucial role in drug formulary decisions.
• Evaluating drugs involves complex, often subjective, assessments of multiple criteria.
• Standardizing these evaluations is essential for consistent and evidence-based decision-making.

Purpose of the Study:

• To introduce a novel system for quantifying subjective drug evaluations within P&T committees.
• To provide a structured, data-driven approach for drug formulary decision-making.
• To enhance the objectivity and comparability of drug assessments.

Main Methods:

• Development of the Formulary Decision Support System (FDSS), a menu-driven database and statistical package.
• Utilizing numerical ratings for drug attributes (effectiveness, cost, adverse reactions) against an ideal drug.
• Incorporating weighted criteria based on importance and individual member expertise/responsibility.

Main Results:

• FDSS successfully converts subjective P&T committee member opinions into quantifiable data.
• The system generates computer reports summarizing individual and overall committee drug ratings.
• Facilitates direct numerical comparisons between different drugs for specific indications.

Conclusions:

• The FDSS offers a systematic method to objectify drug evaluations, moving beyond purely subjective assessments.
• Implementation of FDSS can lead to more consistent, transparent, and defensible formulary decisions.
• This quantitative approach supports evidence-based medicine and resource allocation in healthcare settings.
