The system for controlling and tracking medical items (830) includes a plurality of medical item storage cabinets (878). Each cabinet includes a plurality of doors (888-894). The doors control access to shelves (902, 904) and support modules (1210). Shelves and support modules include user interfaces (938, 1214). Authorized users desiring to take medical items from storage locations in cabinets for use in treating patients are enabled to provide inputs through a display terminal (880) adjacent to cabinets and/or interfaces to indicate the taking of medical items. Storage cabinets include visual indicators so that users may be guided to find a selected medical item for which information is input at an associated display terminal. Alternatively, authorized users gain access to the interior of the cabinet and indicate through appropriate inputs through interfaces on the shelves the types and quantities of items being taken.
