NexusEmrPreventionRoute Naming system

Status: draft · 1.26.0 · JSON

Identifies the administration-route picklist values recorded by the Nexus EMR prevention form. A picked value is written as a coding on Immunization.route beside route.text, and this is that coding's system. Codes are NOT enumerated: the picklist is static app content and the app is the source of truth for it, so an enumeration here would be a snapshot that drifts. A code is the picked label lowercased with runs of whitespace collapsed to a single hyphen, and the coding's display carries the label as the form shows it. The route is a SINGLE axis, so at most one coding under this system appears on an Immunization.route -- unlike the site, which carries two. route.text is written whenever anything was picked, INCLUDING Unknown, which writes the text and no coding; text present with no coding is therefore the normal shape rather than a defect, and an absent coding does not mean an absent pick. A blank pick clears the element entirely. EMR-LOCAL: this system implies no external governance, and consumers should treat values under it as local/raw codes per the raw-code pattern. The Immunization profile leaves route unbound and no standard terminology slicing (SNOMED CT) is claimed by the profiles today; a standard coding carried beside the raw one is a later-phase commitment. The URI is stable and is pinned in stored Coding.system values.
