Informative balloting 2011Jan

Release 1 – US Realm


This standard publishes a DIM specific to emergency medical service in the pre-hospital setting based on the DAM approved in May 2010. The DIM will be balloted as an Informative document. Subsequently, the project will develop interoperability specifications based on the DIM, including, at least, a Patient Run Report from the EMS Agency to the ED and an Annual Report from the Agency to the national sponsor. These specifications will be balloted as DSTU, and implementation guides will be produced.


Business Case (Intended Use, Customers)

Healthcare, including emergency medical services, emergency departments, and inter-facility transportation; and public health


For the purpose of this project Emergency Medical Services (EMS) are defined as a branch of emergency services dedicated to providing out-of-hospital acute medical care and/or transport to definitive care, to patients with illnesses and injuries which the patient, or the medical practitioner, believes constitutes a medical emergency. The EMS DAM is designed to support the creation of specifications to support the interoperability needs of Emergency Medical Services. The US Sponsor desires to bring EMS communication into line with HITSP and NHIN standards to support quality and the ability to benefit from data re-use.
