What is a fundamental requirement of OBRA '90 regarding Medicaid participants?

The correct answer highlights a crucial requirement established by the Omnibus Budget Reconciliation Act of 1990 (OBRA '90) concerning Medicaid participants. The law mandates that pharmacists must conduct a comprehensive review of a patient's entire drug profile before prescribing new medications. This review is essential to ensure that any potential drug interactions, duplications of therapy, and contraindications are identified. The goal is to optimize patient safety and therapeutic outcomes by ensuring that medications prescribed are appropriate, effective, and safe for the patient given their existing medications and health conditions.

This comprehensive review process is part of the broader patient care responsibilities imposed on pharmacists to promote rational drug use and support efficient healthcare delivery. It emphasizes collaboration between healthcare providers to make informed decisions regarding a patient’s treatment plan.
