Existing Wording: The observation resource has the following aspects:

status (mandatory) - all users of observations SHALL be sure of the status of the observation

reliability - provides an estimate of the degree to which quality issues have impacted on the value of an observation

code (mandatory) - describes what was observed. This is the 'name' in the name/value pair assertion pattern used in this

resource

identifier - Unique identifier for this particular observation so it can be recognized in all contexts where it is represented

value - the actual value that was observed

related observations - Other observations that are components of this observation, or provide supporting information, context or

warnings about this observation

subject,.bodySite[x] - the patient, or group of patients, location, or device, that this observation was made on. Note that group of

patients is most often used in veterinary care. For individual patients, the location on the body may also be specified, though this

is often implicit in the Observation.code

applies[x] - The time or time-period the observed value is asserted as being true. For biological subjects - e.g. human patients -

this is usually called the "physiologically relevant time.

interpretation, comments, and reference range: information to help understand the observed value

method, issued, performer - additional information about how the test was performed that may help understand the observation.

The method is often implicit in the Observation.code

Typically, an observation will have either a value or component observations, and not both.

Comment:

not bad idea to have possible. but there is no tradition for routine reporting of this as a discrete fields
