HL7 V3 Models for Exposure

Based on the RIM Changes that were approved through Harmonization, PHER has developed the following models that utilize the various Exposure related changes. At this point, all of these are normative CMETs (links are to the January 2010 ballot site):

  • A_PublicHealthStatement - The Exposure class included in this model illustrates the use of the various new participation types and roles that were introduced into the RIM to handle exposure.
  • R_ExposureAgentCarrier - This CMET, and its two child CMETs (R_ExposureAgentFomite, R_ExposureAgentVector) - This CMET documents the source of an exposure.
  • R_InvestigativeSubject - This CMET documents an entity as the subject of some sort of public health investigation. In the exposure model it is used for general exposure participants as well as the exposure target.
  • E_PublicHealthEntity This CMET and all its child CMETs are used to document that actual things that participate in various ways in the Exposure event.
