We have had the AmerisourceBergen carousels in place for over 4 years. This system was difficult at first as were are an alpha test site. We have 4 carousels and a packaging system that supplies 3 hospitals with 2 more hospitals coming soon. After working closely with the company over the years it works wonderfully. The difference for us is that ABC was able to integrated the system so that our system at St. Joe's can request and re-fill the pyxis machines at the other sites which has cut down on our inventory. It also does a suggested order and splits out and orders our 340B buyback products.
My advise is: Get something that will interface with the other pieces of automation that you might have plus your wholesaler. We have Med Carousells - AcuDoses - NarcStation. All these are McKesson joined by a McKesson wholesaler we buy drugs from. All these pieces "talk" - to a certain extent.
