A method and apparatus is disclosed for providing an integrated communication services (ICS) network that permits
wireless and
wireline data subscribers to share information on a hospital campus using
wireless or
wireline local area networks, or to seamlessly tap into the facility's
central database while in transit away from the hospital. Users interface with the ICS network through the use of a
point of care terminal that resembles a
clipboard and accepts
data entry from a
stylus on an touch screen. The
central database, referred to as the integrated communications clearinghouse (ICC) is adapted to store a communication profile for every network
server on the ICS network. The ICC also maintains a Global
Patient Profile (GPP), consisting of a
patient profile for every patient ever added to the network. The GPP provides the ICC with the capability of providing aggregated data and demographic information (with or without
patient identification), creating “live”
public health statistics through a single query to a central
server. To access the ICS, a user at a
point of care terminal can utilize several paths in order to deliver data to its destination. This may include existing off-the-shelf PCMCIA based peripherals such as:
wireless LANS, standard wired
Ethernet LAN, a land line Modem, or wireless
wide area networks. The wireless
wide area networks may also include several data paths such as a circuit switched cellular, or packet based Cellular Digital Packet Data (CDPD). The actual selection of a particular channel will be service-dependent and a function of the user whereabouts, the desired quality of the connection, and the costs of the connection.
