The official URL for this profile is: 

http://hl7.org/fhir/us/core/StructureDefinition/us-core-condition

This profile sets minimum expectations for the Condition resource to record, search, and fetch a list of conditions associated with a patient. It identifies which core elements, extensions, vocabularies and value sets SHALL be present in the resource when using this profile.

Example Usage Scenarios:

The following are example usage scenarios for the US Core Condition profile:

  • Query for a Patient’s current or historical conditions
  • Record or update a Patient’s conditions

Mandatory and Must Support Data Elements

The following data-elements must always be present (Mandatory definition]) or must be supported if the data is present in the sending system (Must Support definition). They are presented below in a simple human-readable explanation. Profile specific guidance and examples are provided as well. The Formal Profile Definition below provides the formal summary, definitions, and terminology requirements.

Each Condition must have:

  1. a status of the condition*
  2. a category
  3. a code that identifies the condition
  4. a patient

*The status element has the following constraints: SHALL be present if verification status is not entered-in-error and SHALL NOT be present if verification Status is entered-in-error.

Each Condition must support:

  1. a verification status
  2. an encounter
  3. a date of diagnosis*
  4. a date of resolution
  5. a date when recorded*

*See the next section for how the date of diagnosis is represented in this Profile.

Profile specific implementation guidance:

  • The US Core Condition Category Codes support the separate types of conditions so API consumers can separate health concerns, problems, and encounter diagnoses.
  • The 2015 Certification rule requires the use of SNOMED CT for problem list entries. Following the rules for [required] binding to coded data types, ICD or other local codes can be used as translations to SNOMED CT.
  • The US Core Condition Code supports ICD-9-CM for historical purposes only. ICD-10-CM is available and may be used as the primary code for current encounter diagnoses.
  • To search for an encounter diagnosis, query for Conditions that reference the Encounter of interest and have a category of encounter-diagnosis. An example search is shown in the Quick Start section below.
    • When Condition.category is “encounter-diagnosis” the encounter, SHOULD be referenced in Condition.encounter.
  • See SDOH Guidance for more information when exchanging Social Determinants of Health (SDOH) Conditions/Health Concerns.
  • There is no single element in Condition that represents the date of diagnosis. It may be the assertedDate Extension, Condition.onsetDate, or Condition.recordedDate.
    • Although all three are marked as must support, the server is not required to support all.
    • A server SHALL support Condition.recordedDate.
    • A server SHALL support at least one of assertedDate Extension and Condition.onsetDate. A server may support both, which means they support all 3 locations.
    • The client application SHALL support all three elements.

Examples

  • Condition-hc1 is an example of a condition categorized as a “health-concern”
  • Condition-example is an example of a condition categorized as a “problem”
  • Condition-SDOH-example is an example of a condition categorized as a “Social Determinants Of Health”

Notes:

Quick Start

Below is an overview of the required Server RESTful FHIR interactions for this profile - for example, search and read operations - when supporting the US Core interactions to access this profile’s information (Profile Support + Interaction Support). Note that systems that support only US Core Profiles (Profile Only Support) are not required to support these interactions. See the US Core Server CapabilityStatement for a complete list of supported RESTful interactions for this IG.

  • The syntax used to describe the interactions is described here.
  • See the General Guidance section for additional rules and expectations when a server requires status parameters.
  • See the General Guidance section for additional guidance on searching for multiple patients.

Mandatory Search Parameters:

The following search parameters and search parameter combinations SHALL be supported:

  1. SHALL support searching for all conditions including problems, health concerns, and encounter diagnosis for a patient using the patient search parameter:

    GET [base]/Condition?patient={Type/}[id]

    Example:

    1. GET [base]/Condition?patient=1137192

    Implementation Notes: Fetches a bundle of all Condition resources for the specified patient (how to search by reference)

Optional Search Parameters:

The following search parameter combinations SHOULD be supported:

  1. SHOULD support searching using the combination of the patient and clinical-status search parameters:

    GET [base]/Condition?patient={Type/}[id]&clinical-status=http://terminology.hl7.org/CodeSystem/condition-clinical|active,http://terminology.hl7.org/CodeSystem/condition-clinical|recurrance,http://terminology.hl7.org/CodeSystem/condition-clinical|remission

    Example:

    1. GET [base/Condition?patient=1032702&clinical-status=http://terminology.hl7.org/CodeSystem/condition-clinical|active,http://terminology.hl7.org/CodeSystem/condition-clinical|recurrance,http://terminology.hl7.org/CodeSystem/condition-clinical|remission

    Implementation Notes: Fetches a bundle of all Condition resources for the specified patient and all "active" statuses (active,relapse,remission). This will not return any "entered in error" resources because of the conditional presence of the clinicalStatus element. (how to search by reference and how to search by token)

  2. SHOULD support searching using the combination of the patient and category search parameters:

    GET [base]/Condition?patient={Type/}[id]&category={system|}[code]

    Example:

    1. GET [base]/Condition?patient=1032702&category=http://terminology.hl7.org/CodeSystem/condition-category|problem-list-item
    2. GET [base]/Condition?patient=1032702&category=http://hl7.org/fhir/us/core/CodeSystem/condition-category|health-concern
    3. GET [base]/Condition?patient=1032702&category=http://terminology.hl7.org/CodeSystem/condition-category|encounter-diagnosis

    Implementation Notes: Fetches a bundle of all Condition resources for the specified patient and category. (how to search by reference and how to search by token)

  3. SHOULD support searching using the combination of the patient and category and encounter search parameters:

    GET [base]/Condition?patient={Type/}[id]&category={system|}[code]&encounter={Type/}[id]

    Example:

    1. GET [base]/Condition?patient=1032702&category=http://terminology.hl7.org/CodeSystem/condition-category|encounter-diagnosis?encounter=1036

    Implementation Notes: Fetches a bundle of all Condition resources for the specified patient and category and encounter. When category = "encounter-diagnosis" will return the encounter diagnosis for the encounter. (how to search by reference and how to search by token)

  4. SHOULD support searching using the combination of the patient and code search parameters:

    GET [base]/Condition?patient={Type/}[id]&code={system|}[code]

    Example:

    1. GET [base]/Condition?patient=1032702&code=[http://snomed.info/sct|442311008]

    Implementation Notes: Fetches a bundle of all Condition resources for the specified patient and code. (how to search by reference and how to search by token)

  5. SHOULD support searching using the combination of the patient and onset-date search parameters:
    • including support for these onset-date comparators: gt,lt,ge,le
    • including optional support for AND search on onset-date (e.g.onset-date=[date]&onset-date=[date]]&...)

    GET [base]/Condition?patient={Type/}[id]&onset-date={gt|lt|ge|le}[date]{&onset-date={gt|lt|ge|le}[date]&...}

    Example:

    1. GET [base]Condition?patient=555580&onset-date=ge2018-01-14

    Implementation Notes: Fetches a bundle of all Condition resources for the specified patient and date. (how to search by reference and how to search by date)

  6. SHOULD support searching using the combination of the patient and asserted-date search parameters:
    • including support for these asserted-date comparators: gt,lt,ge,le
    • including optional support for AND search on asserted-date (e.g.asserted-date=[date]&asserted-date=[date]]&...)

    GET [base]/Condition?patient={Type/}[id]&asserted-date={gt|lt|ge|le}[date]{&asserted-date={gt|lt|ge|le}[date]&...}

    Example:

    1. GET [base]Condition?patient=555580&asserted-date=ge2018-01-14

    Implementation Notes: Fetches a bundle of all Condition resources for the specified patient and date. (how to search by reference and how to search by date)

  7. SHOULD support searching using the combination of the patient and recorded-date search parameters:
    • including support for these recorded-date comparators: gt,lt,ge,le
    • including optional support for AND search on recorded-date (e.g.recorded-date=[date]&recorded-date=[date]]&...)

    GET [base]/Condition?patient={Type/}[id]&recorded-date={gt|lt|ge|le}[date]{&recorded-date={gt|lt|ge|le}[date]&...}

    Example:

    1. GET [base]Condition?patient=555580&recorded-date=ge2018-01-14

    Implementation Notes: Fetches a bundle of all Condition resources for the specified patient and date. (how to search by reference and how to search by date)

  8. SHOULD support searching using the combination of the patient and abatement-date search parameters:
    • including support for these abatement-date comparators: gt,lt,ge,le
    • including optional support for AND search on abatement-date (e.g.abatement-date=[date]&abatement-date=[date]]&...)

    GET [base]/Condition?patient={Type/}[id]&abatement-date={gt|lt|ge|le}[date]{&abatement-date={gt|lt|ge|le}[date]&...}

    Example:

    1. GET [base]Condition?patient=555580&abatement-date=ge2018-01-14

    Implementation Notes: Fetches a bundle of all Condition resources for the specified patient and date. (how to search by reference and how to search by date)
