Which of the following options are drug utilization management (UM) rules?

The choice involving the requirement for prior authorization for certain medications is a central aspect of drug utilization management (UM) rules. This process is designed to ensure that medications prescribed are necessary, appropriate, and meet safety guidelines. Prior authorization helps in controlling costs and preventing potential misuse of medications by requiring healthcare providers to obtain approval from the insurance company before the medication can be purchased or distributed. This requirement promotes responsible prescribing practices and ensures that patients receive the most effective treatment options tailored to their specific needs.

In the context of drug utilization management, the other options might be relevant but do not encapsulate the specific rules governing drug UM as effectively as the prior authorization requirement. While reviewing patient medication history can play a role in assessing the appropriateness of prescriptions, it is more a component of patient care management than a specific UM rule. Limiting prescription refills and encouraging the use of brand-name medications may not align with the overall goals of drug utilization management, which typically aims to balance the clinical needs of patients with cost-effectiveness and access to necessary treatments.
