Is the overuse of drugs considered prospective or retrospective DUR?

The correct classification of the overuse of drugs pertains to retrospective Drug Utilization Review (DUR). Retrospective DUR examines prescription and patient records after the fact to identify potential medication-related issues that may have occurred, such as overuse of medications. This type of review analyzes historical data to detect patterns of drug use and to assess whether patients are receiving appropriate treatments or experiencing adverse drug events due to their medication regimens.

In contrast, prospective DUR occurs before the dispensing of medications and focuses on evaluating prescriptions for potential drug interactions, allergies, and other issues at the point of care. Concurrent DUR takes place while a patient is receiving treatment, monitoring ongoing therapy to ensure it's effective and safe. The classification as "not classified" does not apply here, as overuse can indeed be assessed through retrospective evaluation, making it crucial to recognize how past usage patterns can inform current prescriptions and healthcare strategies.
