For Medicaid patients, a DUR of drugs dispensed for 189 days is required for what?

The correct answer is focused on the necessity of assessing therapeutic duplication and drug interactions for Medicaid patients over a dispense period of 189 days. Drug Utilization Review (DUR) is an essential process designed to ensure that medications prescribed to patients are appropriate, safe, and effective.

When evaluating a patient’s medication history over such a significant duration, it is crucial to check for therapeutic duplication, which occurs when a patient is prescribed multiple medications that treat the same condition. This can increase the risk of side effects and potentially lead to overdose situations. Additionally, assessing drug interactions is critical, as these can modify the effectiveness of medications or lead to adverse effects when drugs interact negatively with one another.

By conducting a comprehensive DUR that includes both therapeutic duplication and drug interaction checks, healthcare providers can improve patient safety, ensure optimal medication therapy management, and support better health outcomes for Medicaid patients.

In contrast, focusing solely on drug allergies or only on drug-drug interactions would not provide the comprehensive evaluation needed for effective medication management over an extended period. Incorrect dosages and duration of therapy would also be part of a broader assessment but does not encompass the full scope of what a DUR aims to achieve, particularly for Medicaid patients.
