Codes providing the status of an observation.

This case-sensitive code system http://hl7.org/fhir/observation-status defines the following codes in a Is-A heirarchy:

1registered Registered

The existence of the observation is registered, but there is no result yet available.

btn btn
1preliminary Preliminary

This is an initial or interim observation: data may be incomplete or unverified.

btn btn
1final Final

The observation is complete and there are no further actions needed. Additional information such "released", "signed", etc. would be represented using Provenance which provides not only the act but also the actors and dates and other related data. These act states would be associated with an observation status of preliminary until they are all completed and then a status of final would be applied.

btn btn
1amended Amended

Subsequent to being Final, the observation has been modified subsequent. This includes updates/new information and corrections.

btn btn
2  corrected Corrected

Subsequent to being Final, the observation has been modified to correct an error in the test result.

btn btn
1cancelled Cancelled

The observation is unavailable because the measurement was not started or not completed (also sometimes called "aborted").

btn btn
1entered-in-error Entered in Error

The observation has been withdrawn following previous final release. This electronic record should never have existed, though it is possible that real-world decisions were based on it. (If real-world activity has occurred, the status should be "cancelled" rather than "entered-in-error".).

btn btn
1unknown Unknown

The authoring/source system does not know which of the status values currently applies for this observation. Note: This concept is not to be used for "other" - one of the listed statuses is presumed to apply, but the authoring/source system does not know which.

LevelA few code lists that FHIR defines are hierarchical - each code is assigned a level. See Code System for further information.

CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
