Real time data transfer impact on WAN – Every HL7 message generated by the local interface engine is communicated over the WAN to the enterprise IE in ACC. Real time data transfer Performance at CDCO – Processing of all messages and storage of all data at CDCO HDR is completed within one hour of processing through enterprise interface engine Scope Data storage what data is stored – Pharmacy, Allergies and Vitals data are fully mapped and stored in the HDR via the data plug-ins Demographics, Laboratory are fully mapped and stored in the HDR via the 3M ASN.1 standard TIU, Radiology, encounters, health factors and problem list are stored as coded” “loosely text (meaning a lower degree of normalization) Orders are stored as text (all order states) All domains use the data plug-ins as a storage mechanism Windows One of the three sites is a Windows site VMS Site Two of the sites are VMS Cache sites Data Quality Mapped Data A statistically significant sample of all data in each mapped domain is certified via IV&V process Data stored as text A statistically significant sample of all data is each non-computational domain is certified via IV&V process Configuration HDD/MMI Demographics for patients with national ICNs stored in HDR Compliance VHA HL7 v2.4 All messages are certified and accepted by VHA
