Final answer:
A pharmacy using an AMS must maintain written policies and procedures, detailing operations, error handling, inventory management, data security, staff training, and reporting of incidents.
Step-by-step explanation:
A pharmacy using an Automated Medication System (AMS) must maintain WRITTEN policies and procedures. These documents are critical for ensuring the safe and efficient operation of the AMS. For instance, WRITTEN protocols might detail how medications are loaded into the AMS, how to handle discrepancies or errors, inventory management, and the steps for maintaining the system's data security and privacy. Additionally, regulations often require WRITTEN procedures for training staff on the use of the AMS, as well as for monitoring, managing, and reporting any adverse events or medication errors.
