During a Drug Utilization Review, what type of information is primarily evaluated?

During a Drug Utilization Review (DUR), the primary focus is on evaluating the appropriateness and necessity of prescribed medications. This process involves analyzing a patient's medication regimen to ensure that the medications prescribed are suitable for the patient's specific clinical needs, are used in accordance with established guidelines, and do not pose any potential drug interactions or contraindications.

The evaluation typically includes assessing whether medications are being prescribed at the correct dosage, whether there are any duplicate therapies, and whether the medications align with evidence-based practices. The intent of DUR is to promote patient safety and optimize therapeutic outcomes, which is why the appropriateness and necessity of each medication is critically assessed.

Other options, while related to the broader pharmaceutical context, do not directly align with the primary objectives of a DUR. For example, legality of drug imports pertains to regulatory compliance rather than patient medication management, cost-effectiveness is related to economic analysis rather than clinical appropriateness, and marketing strategies involve business practices of pharmaceutical companies rather than clinical evaluations of medication use.
