Observation resource - Edited use case

The "edit" approach for any observation resource will be the same. So this approach applies for "updation" of any data point that is modelled as an observation resource.

• effectiveDateTime - will have the timestamp of the measurement/observation made. This will remain the same unless the user updates also the measurement timestamp
• identifier - will have the same unique identifier with which it has been ingested already
• status - will always be "final" for the updated resource

   

Below is a sample for updating a BG observation with identifier "AAAAA-AAAAA-AAAAA":

   

Step	Description	BG Value	BG Measurement TimeStamp	Type	Identifier
1	A new blood glucose entry is made	170	2018-03-19T06:46:00+00:00	manual entry	AAAAA-AAAAA-AAAAA
2	The entry is updated	177	2018-03-19T06:46:00+00:00	manual entry	AAAAA-AAAAA-AAAAA
3	The entry is updated	178	2018-03-19T06:46:00+00:00	manual entry	AAAAA-AAAAA-AAAAA

The following bundle is generated on Step 2.
