Section 1h: Cross-paradigm/Domain Analysis Models

HL7 Domain Analysis Model: Emergency Care, Release 1 – US Realm


The Emergency Care Domain Analysis Model includes a standardized model of Emergency Department (ED) care processes for use by ED stakeholders, and as informative material for health care domains that interact with the ED. The EC DAM also provides the information framework for incorporating the Data Elements for Emergency Department Systems (DEEDS) into a generic US based hospital emergency department domain model

The scope of the EC DAM is broad, but the intent of this Domain Analysis Model is to create a general foundation for Emergency Care (EC) information needs and to provide an integrated set of EC information artifacts for use by disease specific projects that intersect with EC (such as the CV Chest Pain DAM).


HL7 Domain Analysis Model: Emergency Care, Release 1 – US Realm may also go by the following names or acronyms:

"V3 DAM: Emergency Care, R1", EC DAM


  • Quality Reporting Agencies
  • Regulatory Agency
  • Standards Development Organizations (SDOs)
  • EHR, PHR Vendors
  • Health Care IT Vendors
  • Clinical Decision Support Systems Vendors
  • HIS Vendors
  • Emergency Services Providers
  • Healthcare Institutions (hospitals, long term care, home care, mental health)



  • Provides a high level overview of how HL7 developed HIT related standards can be integrated and applied to the emergency department setting
  • Ensures interoperability of ED data while providing the foundational requirements for EDIS design and use
  • Represents a framework to organize HL7 artifacts in support of the Emergency Care Enterprise Information Requirements
  • Enables developers and implementers of information artifacts related to Emergency Care to understand the inter-relationships between the conceptual models of emergency care and the related information specifications
  • Provides a mapping between terminology models as represented by DEEDS, the many and various Common Message Element Types (CMETs) that provide an underlying information model, and the process model of EC as described by the included business process model
  • Allows mapping of the elements of the Electronic Health Record Functional Model onto those models to create a current EDIS Functional Profile as a model of use
  • Provides a platform specification for use by researchers understanding how to perform clinical research in the ED, policymakers concerned about the impact of policy decisions on the EC, standards developers interacting with the EC domain, and software developers creating FHIR-based applications that interact with the ED
  • Informs further development and refinement of EC related standards.


  • American College of Emergency Physicians ongoing effort to create a Clinical Emergency Data Registry (http://www.acep.org/cedr/).
  • National EMS Information System (www.nemsis.org) in the development of the Emergency Medical Services CDA and the American College of Surgeons Trauma Registry Domain Analysis Model


Members of the HL7 Emergency Care Work Group working collaboratively with Members of the Emergency Informatics Association (Including representation from ACEP, ENA, AAEN, CDC and industry representatives) developed the EC-DAM to provide a framework to understand ED information needs, define interactions between the ED and external systems and to guide innovation, standards development, policies and interoperability for the Emergency Care Enterprise in manner accessible to domain experts and policy makers.

The EC-DAM is not intended to be implementable as there are a myriad of local variations on the details of how Emergency Departments operate in the United States and Worldwide.

Ongoing development to incorporate updated information standards will keep the DAM fresh but never fully up-to-date. We encourage those working with the EC-DAM to contact the Emergency Care Workgroup with questions, concerns and suggestions.
