Which of the following is not an example of drug utilization management (UM) rules?

Chronic disease management focuses on the overall care and support of patients with long-term health conditions, ensuring they receive appropriate treatment and resources to manage their diseases effectively. This approach is more centered on the holistic management of patient health rather than the specific utilization of medications.

In contrast, drug utilization management (UM) rules, such as prior authorization, step therapy, and quantity limits, are specific protocols used to oversee and regulate the prescription and use of medications. Prior authorization requires approval before certain medications are prescribed, ensuring they are necessary and appropriate. Step therapy involves trying less expensive or safer options before moving to more costly or riskier medications, helping to manage costs and ensuring the right treatment path. Quantity limits restrict the number of medication units a patient can receive in a specific time frame, preventing overuse or misuse.

Thus, chronic disease management stands apart as it addresses the broader spectrum of patient care rather than just the management of medication use, making it the correct choice in this context.
