CodeDisplayDefinition
registeredRegisteredThe existence of the observation is registered, but there is no result yet available.
preliminaryPreliminaryThis is an initial or interim observation: data may be incomplete or unverified.
finalFinalThe observation is complete and there are no further actions needed. Additional information such "released", "signed", etc would be represented using [Provenance](provenance.html) 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.
amendedAmendedSubsequent to being Final, the observation has been modified subsequent. This includes updates/new information and corrections.
cancelledCancelledThe observation is unavailable because the measurement was not started or not completed (also sometimes called "aborted").
entered-in-errorEntered in ErrorThe observation has been withdrawn following previous final release.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".).

The type of PlanDefinition.
CodeDisplayDefinition
order-setOrder SetA pre-defined and approved group of orders related to a particular clinical condition (e.g. hypertension treatment and monitoring) or stage of care (e.g. hospital admission to Coronary Care Unit). An order set is used as a checklist for the clinician when managing a patient with a specific condition. It is a structured collection of orders relevant to that condition and presented to the clinician in a computerized provider order entry (CPOE) system.
clinical-protocolClinical ProtocolDefines a desired/typical sequence of clinical activities including preconditions, triggers and temporal relationships.
eca-ruleECA RuleA decision support rule of the form [on Event] if Condition then Action. It is intended to be a shareable, computable definition of actions that should be taken whenever some condition is met in response to a particular event or events.

CodeSystem:ActionGroupingBehavior

Defines organization behavior of a group.
CodeDisplayDefinition
visual-groupVisual GroupAny group marked with this behavior should be displayed as a visual group to the end user.
logical-groupLogical GroupA group with this behavior logically groups its sub-elements, and may be shown as a visual group to the end user, but it is not required to do so.
sentence-groupSentence GroupA group of related alternative actions is a sentence group if the target referenced by the action is the same in all the actions and each action simply constitutes a different variation on how to specify the details for the target. For example, two actions that could be in a SentenceGroup are "aspirin, 500 mg, 2 times per day" and "aspirin, 300 mg, 3 times per day". In both cases, aspirin is the target referenced by the action, and the two actions represent different options for how aspirin might be ordered for the patient. Note that a SentenceGroup would almost always have an associated selection behavior of "AtMostOne", unless it's a required action, in which case, it would be "ExactlyOne".
