Abstract

A wireless, mobile point-of-care system is provided including a plurality of mobile point-of-care carts, each capable of transporting a plurality of patient-specific medication or supply drawers or containers. The mobile point-of-care carts provide for both auto-identification of patient containers carried by the cart, as well as real-time tracking of the carts themselves. Using the combination of these two features, each patient-specific drawer can be located throughout the hospital at any given time. A method is further provided for utilizing this location information to generate a medication delivery/removal plan or route, which can be used by delivery personnel to alleviate the burden caused by making medication carts mobile.
