Class: Visit

Events where Persons engage with the healthcare system for a duration of time. They are often also called “Encounters”. Visits are defined by a configuration of circumstances under which they occur, such as (i) whether the patient comes to a healthcare institution, the other way around, or the interaction is remote, (ii) whether and what kind of trained medical staff is delivering the service during the Visit, and (iii) whether the Visit is transient or for a longer period involving a stay in bed. (OMOP)

    name: id
    description: The 'logical' identifier of the entity within the system of record.  The
      simple value of this attribute stands for an identifier of this data object
      within the system, it can be used as a reference from other objects within the
      same system (i.e. primary and foreign keys), and it should be unique per type
      of object. The same data object copied to a different system will likely have
      a different "id" in the new system since "id" values are system specific and
      do not represent persistent business identifiers. Business identifiers are assigned
      outside the information system and are captured in the "identifier" field. The
      "id" field is more likely to be a serially or randomly generated value that
      is assigned to the data object as it is created in a system.
