Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of its narrative along with other profiles, value sets, etc.

Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource. Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute).

Contained resources do not have a narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later.

Allows users to make use of identifiers when the identifier system is not known.

This element deals only with general categories of identifiers. It SHOULD not be used for codes that correspond 1..1 with the Identifier.system. Some identifiers may fall into multiple categories due to common usage. Where the system is known, a type is unnecessary because the type is always part of the system definition. However systems often need to handle identifiers where the system is not known. There is not a 1:1 relationship between type and system, since many different systems have the same type.

Allows for alternative encodings within a code system, and translations to other code systems.

Codes may be defined very casually in enumerations, or code lists, up to very formal definitions such as SNOMED CT - see the HL7 v3 Core Principles for more information. Ordering of codings is undefined and SHALL NOT be used to infer meaning. Generally, at most only one of the coding values will be labeled as UserSelected = true.

If the value is a full URI, then the system SHALL be urn:ietf:rfc:3986. The value's primary purpose is computational mapping. As a result, it may be normalized for comparison purposes (e.g. removing non-significant whitespace, dashes, etc.) A value formatted for human display can be conveyed using the http://hl7.org/fhir/StructureDefinition/rendered-value). Identifier.value is to be treated as case sensitive unless knowledge of the Identifier.system allows the processer to be confident that non-case-sensitive processing is safe.

For planning purposes, Appointments may include a CareTeam participant to indicate that one specific person from the CareTeam will be assigned, but that assignment might not happen until the Encounter begins. Hence CareTeam is not included in Encounter.participant, as the specific individual should be assigned and represented as a Practitioner or other person resource.

Similarly, Location can be included in Appointment.participant to assist with planning. However, the patient location is tracked on the Encounter in the Encounter.location property to allow for additional metadata and history to be recorded.

The role of the participant can be used to declare what the actor will be doing in the scope of this encounter participation.

If the individual is not specified during planning, then it is expected that the individual will be filled in at a later stage prior to the encounter commencing.

If the precision on these values is low (e.g. to the day only) then this may be considered was an all day (or multi-day) encounter, unless the duration is included, where that amount of time occurred sometime during the interval.

The reason communicates what medical problem the patient has that should be addressed during the episode of care. This reason could be patient reported complaint, a clinical indication that was determined in a previous encounter or episode of care, or some planned care such as an immunization recommendation. In the case where you have a primary reason, but are expecting to also address other problems, you can list the primary reason with a use code of 'Chief Complaint', while the other problems being addressed would have a use code of 'Reason for Visit'.

Examples:

• pregnancy would use HealthcareService or a coding as the reason
• patient home monitoring could use Condition as the reason

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

• ele-1: All FHIR elements must have a @value or children

Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

Used to track patient's diet restrictions and/or preference. For a complete description of the nutrition needs of a patient during their stay, one should use the nutritionOrder resource which links to Encounter.

For example, a patient may request both a dairy-free and nut-free diet preference (not mutually exclusive).
