Location

Unique code or number identifying the location to its users.

Organization label locations in registries, need to keep track of those.

The rules of the identifier.type determine if a check digit is part of the ID value or sent separately, such as through the checkDigit extension.

The operational status covers operation values most relevant to beds (but can also apply to rooms/units/chairs/etc. such as an isolation unit/dialysis chair). This typically covers concepts such as contamination, housekeeping, and other activities like maintenance.

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.

The operational status if the location (where typically a bed/room).

Description of the Location, which helps in finding or referencing the place.

Humans need additional information to verify a correct location has been identified.

Systems are not required to have markdown support, so the text should be readable without markdown processing. The markdown syntax is GFM - see https://github.github.com/gfm/

Indicates whether a resource instance represents a specific location or a class of locations.

When using a Location resource for scheduling or orders, we need to be able to refer to a class of Locations instead of a specific Location.

This is labeled as a modifier because whether or not the location is a class of locations changes how it can be used and understood.

Indicates whether a resource instance represents a specific location or a class of locations.

Indicates the type of function performed at the location.

Not all terminology uses fit this general pattern. In some cases, models should not use CodeableConcept and use Coding directly and provide their own structure for managing text, codings, translations and the relationship between elements and pre- and post-coordination.

Indicates the type of function performed at the location.

The contact details of communication devices available at the location. This can include addresses, phone numbers, fax numbers, mobile numbers, email addresses and web sites.

Need to keep track of both simple contact details and also assigned contacts within larger organizations.

The address/telecom use code 'home' are not to be used. Note that these contacts are not the contact details of people who provide the service (that would be through PractitionerRole), these are official contacts for the Healthcare itself for specific purposes. E.g. Mailing Addresses, Billing Addresses, Contact numbers for Booking or Billing Enquiries, general web address, web address for online bookings etc.

If this is empty (or the type of interest is empty), refer to the organization's contacts.

Physical location.

If locations can be visited, we need to keep track of their address.

Additional addresses should be recorded using another instance of the Location resource, or via the Organization.

Physical form of the location, e.g. building, room, vehicle, road, virtual.

For purposes of showing relevant locations in queries, we need to categorize locations.

Not all terminology uses fit this general pattern. In some cases, models should not use CodeableConcept and use Coding directly and provide their own structure for managing text, codings, translations and the relationship between elements and pre- and post-coordination.

Physical form of the location.

Longitude. The value domain and the interpretation are the same as for the text of the longitude element in KML (see notes on Location main page).

Do not use an IEEE type floating point type, instead use something that works like a true decimal, with inbuilt precision (e.g. Java BigInteger)

Latitude. The value domain and the interpretation are the same as for the text of the latitude element in KML (see notes on Location main page).

Do not use an IEEE type floating point type, instead use something that works like a true decimal, with inbuilt precision (e.g. Java BigInteger)

Altitude. The value domain and the interpretation are the same as for the text of the altitude element in KML (see notes on Location main page).

Do not use an IEEE type floating point type, instead use something that works like a true decimal, with inbuilt precision (e.g. Java BigInteger)

The expected type of the target of the reference. If both Reference.type and Reference.reference are populated and Reference.reference is a FHIR URL, both SHALL be consistent.

The type is the Canonical URL of Resource Definition that is the type this reference refers to. References are URLs that are relative to http://hl7.org/fhir/StructureDefinition/ e.g. "Patient" is a reference to http://hl7.org/fhir/StructureDefinition/Patient. Absolute URLs are only allowed for logical models (and can only be used in references in logical models, not resources).

This element is used to indicate the type of the target of the reference. This may be used which ever of the other elements are populated (or not). In some cases, the type of the target may be determined by inspection of the reference (e.g. a known RESTful URL) or by resolving the target of the reference.

Aa resource (or, for logical models, the URI of the logical model).

The purpose of this identifier.

Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers.

Applications can assume that an identifier is permanent unless it explicitly says that it is temporary.

Identifies the purpose for this identifier, if known .

The version of the code system which was used when choosing this code. Note that a well-maintained code system does not need the version reported, because the meaning of codes is consistent across versions. However this cannot consistently be assured, and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged.

Where the terminology does not clearly define what string should be used to identify code system versions, the recommendation is to use the date (expressed in FHIR date format) on which that version was officially published as the version date.

A representation of the meaning of the code in the system, following the rules of the system.

Need to be able to carry a human-readable meaning of the code for readers that do not know the system.

Note that FHIR strings SHALL NOT exceed 1,048,576 (1024*1024) characters in size

Indicates that this coding was chosen by a user directly - e.g. off a pick list of available items (codes or displays).

This has been identified as a clinical safety criterium - that this exact system/code pair was chosen explicitly, rather than inferred by the system based on some rules or language processing.

Amongst a set of alternatives, a directly chosen code is the most appropriate starting point for new translations. There is some ambiguity about what exactly 'directly chosen' implies, and trading partner agreement may be needed to clarify the use of this element and its consequences more completely.

A human language representation of the concept as seen/selected/uttered by the user who entered the data and/or which represents the intended meaning of the user.

The codes from the terminologies do not always capture the correct meaning with all the nuances of the human using them, or sometimes there is no appropriate code at all. In these cases, the text is used to capture the full meaning of the source.

Very often the text is the same as a displayName of one of the codings.

Establishes the namespace for the value - that is, an absolute URL that describes a set values that are unique.

There are many sets of identifiers. To perform matching of two identifiers, we need to know what set we're dealing with. The system identifies a particular set of unique identifiers.

Identifier.system is always case sensitive.

The portion of the identifier typically relevant to the user and which is unique within the context of the system.

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.

Time period during which identifier is/was valid for use.

A Period specifies a range of time; the context of use will specify whether the entire range applies (e.g. "the patient was an inpatient of the hospital for this time range") or one value from the range applies (e.g. "give to the patient between these two times").

Period is not used for a duration (a measure of elapsed time). See Duration.

Organization that issued/manages the identifier.

The Identifier.assigner may omit the .reference element and only contain a .display element reflecting the name or other textual information about the assigning organization.

Plain text narrative that identifies the resource in addition to the resource reference.

This is generally not the same as the Resource.text of the referenced resource. The purpose is to identify what's being referenced, not to fully describe it.

Another Location of which this Location is physically a part of.

For purposes of location, display and identification, knowing which locations are located within other locations is important.

References SHALL be a reference to an actual FHIR resource, and SHALL be resolvable (allowing for access control, temporary unavailability, etc.). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository.

Collection of characteristics (attributes).

These could be such things as is wheelchair accessible.

A custom attribute that could be provided at a service (e.g. Wheelchair accessibiliy).

What days/times during a week is this location usually open, and any exceptions where the location is not available.

This type of information is commonly found published in directories and on websites informing customers when the facility is available.

Specific services within the location may have their own hours which could be shorter (or longer) than the locations hours.

Systems may choose to render availability differently than it is exchanged on the interface. For example, rather than "Mon, Tue, Wed, Thur, Fri from 9am-12am; Mon, Tue, Wed, Thur, Fri from 1pm-5pm" as would be implied by two availableTime repetitions, an application could render this information as "Mon-Fri 9-12am and 1-5pm".

The availableStartTime is the opening time, and the availableEndTime is the closing time.

Connection details of a virtual service (e.g. shared conference call facility with dedicated number/details).

There are two types of virtual meetings that often exist:

• a persistent, virtual meeting room that can only be used for a single purpose at a time,
• and a dynamic virtual meeting room that is generated on demand for a specific purpose.

Implementers may consider using Appointment.virtualService for virtual meeting rooms that are generated on-demand.

Technical endpoints providing access to services operated for the location.

Organizations may have different systems at different locations that provide various services and need to be able to define the technical connection details for how to connect to them, and for what purpose.

References SHALL be a reference to an actual FHIR resource, and SHALL be resolvable (allowing for access control, temporary unavailability, etc.). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository.
