Which statement best describes a Drug Usage Evaluation (DUE)?

• A. A financial audit of drug expenditures
• B. A process to evaluate the appropriate use of medications
• C. A survey of patient satisfaction with medications
• D. A check of pharmacy inventory levels

Answer: (B)

Drug Usage Evaluation is a quality improvement process that looks at how medications are used to ensure they are appropriate, safe, and effective for patients. It involves reviewing indications, dosing and duration, potential drug interactions or contraindications, and monitoring for adverse effects, all against evidence-based criteria and actual patient data. The aim is to identify and correct suboptimal prescribing, improving therapeutic outcomes and informing education or policy changes. This isn’t about financial audits, patient satisfaction surveys, or inventory checks, which focus on costs, experiences, or stock management rather than the appropriateness of drug use.
