Which act requires careful management of how pharmacists interact with patients?

The correct answer relates to OBRA '90, which stands for the Omnibus Budget Reconciliation Act of 1990. This act introduced significant regulations aimed at improving patient care in pharmacy practice, particularly emphasizing the interaction between pharmacists and patients.

One of the major components of OBRA '90 is the mandate for pharmacists to offer counseling to patients on their medications, ensuring they understand the medication’s purpose, proper usage, potential side effects, and any interactions with other drugs. Additionally, it requires pharmacists to perform drug utilization reviews to identify and resolve any medication-related issues. This focus on patient interaction and education directly enhances medication safety and improves health outcomes.

The other acts listed might address various issues related to pharmacy practice, such as privacy, substance abuse treatment, and the regulation of specific medications, but they do not focus primarily on the management of pharmacist-patient interactions to the same degree as OBRA '90.
