|DotNet Class HL7Connect.Cda.EIVL|
Specifies a periodic interval of time where the recurrence is based on activities of daily living or other important events that are time-related but not fully determined by time.
Example: "one hour after breakfast" specifies the beginning of the interval at one hour after breakfast is finished. Breakfast is assumed to occur before lunch but is not determined to occur at any specific tim
|A code for a common (periodic) activity of daily living based on which the event related periodic interval is specified. Events that qualify for being adopted in the domain of this attribute must satisfy the following requirements:|
· the event commonly occurs on a regular basis
· the event is being used for timing activities, and
· the event is not entirely determined by time
If these criteria are not met, the relationship of the event and its time must be communicated using structures outside the datatypes defined in this standard.
If populated, the value of this attribute SHALL be taken from the HL7 TimingEvent code system. -- Lists Timing events that a repeating event may relate to
|An interval of elapsed time (duration, not absolute point in time) that marks the offsets for the beginning, width and end of the EIVL measured from the time each such event actually occurred. |
Example: if the specification is "one hour before breakfast for 10 minutes", code is CM, IVL.low of offset is -1 h and the IVL.high of offset is -50 min.
The offset SHALL be null if the event code specifies "before", "after" or "between meals". The offset SHALL be nonNull if the EIVL is nonNull and the event code is C, CM, CD, or CV. The offset may or may not be null for the event codes HS and WAKE.
