Health Connect Australia Provider Directory FHIR Implementation Guide

Health Connect entry for a healthcare service at a location by an organisation.

A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.

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 it's narrative along with other profiles, value sets, etc.

An Extension

Indicates the IAR (Initial Assessment and Referral) Levels of Care for a healthcare service.

Context of Use: HealthcareService

Codes from: http://ns.electronichealth.net.au/hc/CodeSystem/hc-iar-levels-of-care

Indicates if Healthcare service is accepting new patients. A value of True means the service is accepting new patients.

Information for referrers about referral requirements for this healthcare service.

The time period during which the HealthcareService is considered active in the HealthConnect directory.

May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions.

Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).

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.

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.

Identifier for the organization that is used to identify the healthcare service across multiple disparate systems.

This flag is used to mark the record to not be used. This is not used when a center is closed for maintenance, or for holidays, the notAvailable period is to be used for this.

This element is labeled as a modifier because it may be used to mark that the resource was created in error.

The organization that provides this healthcare service.

This property is recommended to be the same as the Location's managingOrganization, and if not provided should be interpreted as such. If the Location does not have a managing Organization, then this property should be populated.

The specific type of service that may be delivered or performed.

A reference to a code defined by a terminology system.

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.

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

A symbol in syntax defined by the system. The symbol may be a predefined code or an expression in a syntax defined by the coding system (e.g. post-coordination).

List of contacts related to this specific healthcare service.

If this is empty, then refer to the location's contacts.

The location(s) that this service is available to (not where the service is provided).

The locations referenced by the coverage area can include both specific locations, including areas, and also conceptual domains too (mode = kind), such as a physical area (tri-state area) and some other attribute (covered by Example Care Organization). These types of Locations are often not managed by any specific organization. This could also include generic locations such as "in-home".

The code(s) that detail the conditions under which the healthcare service is available/offered.

The provision means being commissioned by, contractually obliged or financially sourced. Types of costings that may apply to this healthcare service, such if the service may be available for free, some discounts available, or fees apply.

Indicates which days of the week are available between the start and end Times.

The days of the week.

Is this always available? (hence times are irrelevant) e.g. 24 hour service.

The opening time of day. Note: If the AllDay flag is set, then this time is ignored.

The time zone is expected to be for where this HealthcareService is provided at.

An IANA timezone code for the timezone offset per BCP 175. For data types allowing the offset (all except date and time), this extension SHALL agree with the offset if provided and cannot be used in place of the offset if the precision expressed requires an offset. Where an offset is provided, this extension provides a more legible display of the zone associated with the offset. Where an offset is not present, this extension can be used to provide zone information not otherwise available.

These are codes like "America/New_York" or "America/Los_Angeles". See https://www.iana.org/time-zones for the official source, and https://en.wikipedia.org/wiki/List_of_tz_database_time_zones for more information.

Health Connect entry for a healthcare service at a location by an organisation.

The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.

The only time that a resource does not have an id is when it is being submitted to the server using a create operation.

The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource.

A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.

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 it's narrative along with other profiles, value sets, etc.

The base language in which the resource is written.

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).

A human language.

A human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety.

Contained resources do not have 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.

These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, and nor can they have their own independent transaction scope.

This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags In their meta elements, but SHALL NOT have security labels.

Identifies the broad category of service being performed or delivered.

Selecting a Service Category then determines the list of relevant service types that can be selected in the primary service type.

A category of the service(s) that could be provided.

The specific type of service that may be delivered or performed.

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

The identification of the code system that defines the meaning of the symbol in the code.

The URI may be an OID (urn:oid:...) or a UUID (urn:uuid:...). OIDs and UUIDs SHALL be references to the HL7 OID registry. Otherwise, the URI should come from HL7's list of FHIR defined special URIs or it should reference to some definition that establishes the system clearly and unambiguously.

Need to be unambiguous about the source of the definition of the symbol.

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 symbol in syntax defined by the system. The symbol may be a predefined code or an expression in a syntax defined by the coding system (e.g. post-coordination).

Need to refer to a particular code in the system.

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.

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

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.

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.

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.

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

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.

Collection of specialties handled by the service site. This is more of a medical term.

The location where this healthcare service may be provided.

Further description of the service as it would be presented to a consumer while searching.

Additional details, that the service provider can add for their directory listing, as a free text, that is not covered by other available data elements.

The locations referenced by the coverage area can include both specific locations, including areas, and also conceptual domains too (mode = kind), such as a physical area (tri-state area) and some other attribute (covered by Example Care Organization). These types of Locations are often not managed by any specific organization. This could also include generic locations such as "in-home".

The code(s) that detail the conditions under which the healthcare service is available/offered.

Eligibility requirements for the healthcare service, bound to the HealthConnect Service Eligibility ValueSet.

Describes the eligibility conditions for the service.

The description of service eligibility should, in general, not exceed one or two paragraphs. It should be sufficient for a prospective consumer to determine if they are likely to be eligible or not. Where eligibility requirements and conditions are complex, it may simply be noted that an eligibility assessment is required. Where eligibility is determined by an outside source, such as an Act of Parliament, this should be noted, preferably with a reference to a commonly available copy of the source document such as a web page.

Programs that this service is applicable to.

Programs are often defined externally to an Organization, commonly by governments; e.g. Home and Community Care Programs, Homeless Program, ….

Government or local programs that this service applies to.
