Communication between EHRs (and other clinical systems) and Emergency Management (EM) and Emergency Medical Services (EMS) systems is critical for patient care. HL7 has worked with OASIS to provide resources to enhance interoperability in this domain.
TEP Message Transforms
OASIS EDXL-TEP is an OASIS Emergency Management Technical Committee (EM-TC) international public standard that enables emergency patient tracking data exchange between the myriad of systems used by Emergency Management (EM) and Emergency Medical Services (EMS). Patient movement, condition, and care are tracked and shared throughout the emergency continuum of care, from initial encounter with emergency services to the point of admittance to a healthcare facility. This specification provides a mechanism for hospitals/EDs to track incoming patients from emergency services in the field via existing HL7 conformant systems. It also includes the specification for transforming an HL7 V2.7.1 message to an EDXL-TEP message if a patient must be transported from the healthcare facility by emergency services to another healthcare facility (e.g. Hospital Evacuation).
HAVE 2.0 Alignment
Emergency Management actors use, for the most part, OASIS Emergency Management standards for communicating relevant information. HAVE addresses the status and availability of hospital and ED resources. Most hospital/ED systems primarily employ HL7 for messaging. A bridge between the HAVE and HL7 messages in the HAVE standard would improve information exchange between emergency management and hospitals/EDs.
