What are the standards for DUR according to regulatory guidelines?

The correct choice highlights that drug utilization review (DUR) standards are informed by the American Hospital Formulary Service and peer-reviewed literature. This is significant because these resources provide evidence-based guidelines and comprehensive evaluations of medications that help in assessing their effectiveness, safety, and appropriateness.

Using the American Hospital Formulary Service ensures that pharmacists have access to credible and standardized drug information that is widely accepted within the medical community. Peer-reviewed literature enhances these standards by incorporating the latest research findings and clinical studies, which are vital for making informed decisions regarding patient care and medication management.

The choice of World Health Organization guidelines, while important for global health initiatives, does not directly address the specific and localized needs of drug utilization reviews as framed by local or national healthcare systems. Similarly, relying solely on the American Medical Association or individual pharmacies lacks the comprehensive and evidence-based approach provided by the resources mentioned in the correct answer. Thus, choice B represents the most authoritative and balanced approach to establishing DUR standards.
