[Evaluation of drug utilization from positive lists]

Area of Science:

• Pharmacoeconomics
• Drug utilization research
• Health services research

Context:

• Rising drug expenditures necessitate cost-control mechanisms.
• Positive drug lists are a key regulatory strategy.
• Analyzing drug consumption trends is crucial for cost management.

Purpose:

• To introduce and evaluate the DU 90% method for drug consumption analysis.
• To utilize a 90% ratio of drug preparations in total consumption analysis.
• To assess the effectiveness of drug lists in cost reduction.

Summary:

• The DU 90% method was applied to hospital prescriptions, classifying drugs by ATC groups and using defined daily doses.
• Calculations identified 116-142 drugs within the DU 90% interval, with consistent positive list drug ratios across departments.
• Anti-infectives and drugs affecting blood/hematopoietic organs represented the highest expenditures.

Impact:

• The DU 90% method offers an easy, low-cost approach to identify areas for pharmacotherapy improvement.
• Facilitates qualitative and quantitative evaluation of pharmacotherapy standards.
• Supports evidence-based decision-making in drug formulary management.
