Records that a diagnostic report has been sent to Ontario Health's ACDR. Carried as a tag on
DiagnosticReport.meta.tag, where this is the tag's system.
A tag, not an extension. The address identifies the system of a Coding in meta.tag, which
is why it is declared as a code system. The vocabulary is the unusual part: the codes are the
literal strings true and false, the writer's rendering of a boolean.
Absent means not sent -- and nothing more. It does not distinguish "not yet sent" from "will never be sent": a report carries no tag when its site is not configured to send, when its status is not one that is sent, or when its code is not one that is sent. The tag is a record of delivery and not of eligibility or of intent.
true means the receiver acknowledged the report. It is written only after an accepting
acknowledgement comes back; a rejected or failed send leaves the report untagged so it can be
retried. It records nothing about WHICH version was accepted, or when -- it is a fact about the
report rather than about one version of it, and nothing clears it, so a report revised after a send
still carries it. A consumer that needs the timing, the version, or the acknowledgement itself
should read AuditEvent.
false is representable but is not written. The vocabulary is closed by the boolean it is
rendered from, so both codes are listed; only true is emitted. Read false exactly as an absent
tag, compare case-insensitively, and treat anything that is not true as not sent rather than as
an error.
One tag per system, and this system carries one fact. A writer replaces any existing tag with
this system rather than adding a second. The parallel record of delivery downstream is a separate
system, ../CodeSystem/diagnostic-report-sent-downstream, precisely so that
the two can be held at once.
Nexus EMR writes this today at
http://services.well.com/fhir/tags/diagnostic-reports/acdr-sent (FHIR-371): it is live in
stored DiagnosticReport.meta.tag codings and in code, and is under migration to the canonical
declared here. Write the canonical; expect both until the migration completes, and match both
addresses exactly rather than deriving one from the other.
| Code | Display | Definition |
|---|---|---|
true |
Sent | The report has been sent to Ontario Health's ACDR and the receiver acknowledged it. Records the delivery, not which version was delivered or when. |
false |
Not sent | The report has not been sent. Representable but not written by Nexus EMR; a reader should treat it exactly as an absent tag. |
