© IHE This document provides an overview of the HIMSS 2009 New Directions IHE PCD DPI door poster. Use Case scope is summarized in the following table. Harmonization Use Matrix Developed from contributions by several harmonization* working groups Initial phase focuses on normalization of acute care data interchange representation and transportation (see Phasing) Table, p.8

© IHE DPI PoC [w]P/LAN DPI Point-of-Care (PoC) acute care Patient/Local Area Network (P/LAN), incl. wirelesss (wP/LAN) Supervisory Control and Data Acq’n (SCADA): may be local or remote, wired or wireless, patient- or body-area network-based (wP/LAN). Transport without data transform via Clinical LAN is necessary to integrate patient data from mobile location(s), e.g. Ancillaries, to “home- bed” and “home-nurses’ station[s]” Transport with data transform (e.g. IEEE HL7 v2.x is necessary for integration in Clinical Document Arch.
