What is the role of drug utilization management (UM) in Medicare?

The role of drug utilization management (UM) in Medicare primarily focuses on ensuring that medications prescribed to patients are appropriate for their condition while also managing costs effectively. This involves assessing medication usage patterns to identify any inappropriate prescriptions, potential for drug interactions, effectiveness of prescribed therapies, and adherence to clinical guidelines. By implementing these strategies, UM aims to optimize therapeutic outcomes for patients, ensuring that they receive the most suitable medications that align with best practices. Additionally, by controlling unnecessary expenditures, it helps maintain the sustainability of the Medicare program.

Other options may suggest approaches that do not align with the primary objectives of UM, such as merely increasing the number of prescriptions or mandating the use of generics without evaluating the appropriateness for individual patient needs. The emphasis on controlling costs along with promoting the appropriate use of medication distinguishes the correct answer as the most comprehensive reflection of UM's role in Medicare.
