Observation Delete use case

The "Delete" approach for observation resource will be as below. So this approach applies for any data point that is modelled as observation resource.

• effectiveDateTime - will have the timestamp of the measurement/observation made.
• identifier - will have the same unique identifier with which it has been ingested already
• status - will always be "cancelled" for the deleted resource

   

Below is a sample for deleting a BG observation with internal confidence ID "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 deleted; In FHIR it is logically deleted by replacing it with "cancelled" status		2018-03-19T06:46:00+00:00

The following bundle is generated on Step 3.
