A acuity entry indicates the triage acuity entry and the triage time of the patient.

The code describes the triage acuity scale. IHE recommends the use the Emergency Severity Index (ESI). However, the vocabulary used within an affinity domain may be determined by a policy agreement within the domain.
This is a reference to the narrative text within the section that describes the acuity description.
This is a reference to the narrative text corresponding to the Observation act.
The effectiveTime element shall be sent. It records the interval of time over which triage occurs. The use case for this information requires that the ending time of triage be recorded. However, the <low value=' '> element may be sent by systems that capture the beginning and end of the triage process.
<high value=' '/>
This element records the time of completion of triage, and is required. If unknown, it must be recorded using a flavor of null. This element may be sent using the TS data type, as shown above. If there is uncertainty about the time of completion of triage, the sender may record the time using the IVL_TS data type, as shown below.
<high xsi:type='IVL_TS'> <low value=''/> <high value=''/> </high>
