What must be ensured when using an Automated Dispensing System (ADS) in long-term care?

When using an Automated Dispensing System (ADS) in long-term care, it is essential to have a separate DEA number for each dispensing machine. This requirement is important because each ADS is considered a separate entity for the purpose of controlled substance distribution. Therefore, having a unique DEA number for each machine helps ensure compliance with federal regulations governing the handling and dispensing of controlled substances.

This necessity for separate DEA registrations addresses accountability and traceability, allowing for proper monitoring of the controlled substances dispensed from each specific machine. It also facilitates the ability to identify any potential discrepancies or issues with inventory management within the facility.

The other options do not align with established regulations regarding ADS in long-term care settings. Storing all medications in the patient's room may not comply with safety and security protocols, while having a single DEA registration for all facilities can lead to complications in tracking controlled substances. Lastly, maintaining records at the central pharmacy is crucial for ensuring compliance and accountability in the dispensing process, contrary to the suggestion that no records are required.
