Issue
In public health reporting it is often important to report not just the effective time of some act, but the activity time associated with the act as well.
Recommendation
- Add the activityTime attribute to the Observation, SubstanceAdministration, Supply, Procedure, Encounter and Act classes in the CS model.
Rationale
There are at least two circumstances in public health reporting where knowing activity time is important. The first is from an administrative perspective, it is important to capture when investigations begin and end. The end of an investigation is often documented via final report. The second circumstance where activity time is important is when investigating some public health event, it is important not just to document the effective time of the event, but all the time spent by participants involved in the event. Since effective time does not capture administrative time, activity time is needed to properly capture all time, administrative or otherwise associated with an event.
Discussion
Activity time captures all time spent on some act (including administrative time) not just the effective time of an act.
Recommended Action Items
Add the following attribute to the Observation, SubstanceAdministration, Supply, Procedure, Encounter and Act classes:
- activityTime – GTS [0..1] optional
- A time expression specifying when an Act occurs, or, depending on the mood, is supposed to occur, scheduled to occur, etc. The activityTime includes the times of component actions (such as preparation and clean-up). The activityTime is primarily of administrative rather than clinical use. The clinically relevant time is the effectiveTime. When an observation of a prior symptom is made, the activityTime describes the time the observation is made, as opposed to effectiveTime which is the time the symptom is reported to have occurred. Thus the activityTime may be entirely different from the effectiveTime of the same Act.
