The IE Core Observation Screening Assessment Profile inherits from the FHIR Observation resource; refer to it for scope and usage definitions. This profile meets the requirements of the iEHR IE Core Data for Interoperability (IECDI) Health Status Assessments Data Class. It sets the minimum expectations for the Observation Resource to record, search, and fetch observations representing the questions and responses to surveys and screening and assessment tools. For example, a social history status such as education or food insecurity or an assessment of cognitive, functional, or disability status. It can represent a single response, multiple responses, and multi-select "check all that apply" type questions. This profile specifies which core elements, extensions, vocabularies, and value sets SHALL be present in the resource and constrains how the elements are used. Providing the floor for standards development for specific use cases promotes interoperability and adoption. Before reviewing this profile, implementers are encouraged to read the Screening and Assessments guidance page, which documents the process of recording responses and capturing assertions/determinations resulting from surveys and questionnaires.

This page is new content for IE Core Version 1.0.0

Example Usage Scenarios:

The following are example usage scenarios for this profile:

  • Query for screening or assessment results for a patient.
  • Record or update screening and assessment results belonging to a Patient

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 Views below provides the formal summary, definitions, and terminology requirements.

  1. a status
  2. a category code of "survey"
  3. a LOINC code, if available, which tells you the survey question
  4. a patient

Each Observation Must Support:

  1. additional categories that further specify the assessment or screening
  2. a time indicating when the survey was taken
  3. the answer or a reason why the data is absent*
    • if the result value is a numeric quantity and coded quantity units are used, UCUM is required.
  4. who answered the questions (in other words, a performer)*
  5. related questionnaire responses or observations that this observation is made from
  6. reference to observations that make up this observation*

* see guidance below

Profile Specific Implementation Guidance:

  • *See the Screening and Assessments guidance page for how this profile represents surveys, screenings, and assessments.
    • Each response to individual questions and each answer to a multi-select or "check all that apply" question is a separate IE Core Screening and Assessments Observation. The question is communicated in Observation.code, and the answer is in Observation.value.
    • Multi-question screenings and assessments use the IE Core Screening and Assessments Observation to represent a "panel" or grouping. The multi-question surveys or assessments Observation.code is an overarching assessment or screening code, and the Observation.value element SHOULD be empty. Observation.hasMember references IE Core Screening and Assessments Observations that represent the responses to each question in the screening or assessment.
  • A practitioner's clinical observation or assertion about a patient's health status, which is not a response to a screening or assessment question, SHOULD use the IE Core Simple Observation Profile instead.
  • The category type 'survey' is required, and a set of categories that represent the IECDI data elements and further specify the assessment must be supported. Because of technical requirements, a value set with a Required Binding is needed for IECDI categories. However, other categories are permitted. The Observation.category element provides an efficient way of restricting search on observations to a given context such as survey observations. Example searches are shown in the Quick Start section below. However, clients need to understand that data categorization is somewhat subjective. The categorization applied by the source may not align with the client's expectations. Clients may find it more useful to use queries based on a specific code or set of codes or to perform additional client-side filtering of query results.
  • *An Observation without a value, SHALL include a reason why the data is absent unless there are 1) component observations, or 2) reporting panel observations using Observation.hasMember.
    • For further guidance, see the Observation Grouping section in FHIR Specification.
    • Systems that never provide an observation without a value are not required to support Observation.dataAbsentReason.
  • *An Observation.component without a value, SHALL include a reason why the data is absent.
    • Systems that never provide a component observation without a component value are not required to support Observation.component.dataAbsentReason.
  • *Although 'Observation.performer' target profiles IE Core Practitioner Profile and IE Core Patient Profile are labeled Must Support. Servers are not required to support both, but SHALL support at least one. Clients SHALL support both.
  • *Although 'Observation.derivedFrom' target profiles Observation and IE Core QuestionnaireResponse Profile are labeled Must Support. The certifying server system is not required to support both, but SHALL support at least one. The client application SHALL support both.

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 IE Core interactions to access this profile's information (Profile Support + Interaction Support). Note that systems that support only IE Core Profiles (Profile Only Support) are not required to support these interactions. See the IE Core Server CapabilityStatement for a complete list of supported RESTful interactions for this IG.

  • See the Scopes Format section for a description of the SMART scopes syntax.
  • See the Search Syntax section for a description of the IE Core search syntax.
  • See the General Requirements 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.

IE Core Scopes

Servers providing access to assessment data SHALL support these IE Core SMART Scopes:

  • resource level scopes: <patient|user|system>/Observation.rs

  • granular scopes: <patient|user|system>.Observation.rs?category=http://terminology.hl7.org/CodeSystem/observation-category|survey

  • granular scopes: <patient|user|system>.Observation.rs?category=http://iehr.ai/fhir/ie/core/CodeSystem/ie-core-category|sdoh

Mandatory Search Parameters:

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

  1. SHALL support searching using the combination of the patient and category search parameters:

    GET [base]/Observation?patient={Type/}[id]&category=http://terminology.hl7.org/CodeSystem/observation-category|laboratory

    Example:

    1. GET [base]/Observation?patient=1134281&amp;category=survey

    Implementation Notes: Fetches a bundle of all Observation resources for the specified patient and a category code = laboratory (how to search by reference and how to search by token)

  2. SHALL support searching using the combination of the patient and code search parameters:
    • including optional support for OR search on code (e.g.code={system|}[code],{system|}[code],...)

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

    Example:

    1. GET [base]/Observation?patient=1134281&amp;code=http://loinc.org|9271-8
    2. GET [base]/Observation?patient=1134281&amp;code=http://loinc.org|9271-8,http://loinc.org|32405-3,http://loinc.org|32403-8

    Implementation Notes: Fetches a bundle of all Observation resources for the specified patient and observation code(s). SHOULD support search by multiple report codes. The Observation code parameter searches `Observation.code only. (how to search by reference and how to search by token)

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

    GET [base]/Observation?patient={Type/}[id]&category=http://terminology.hl7.org/CodeSystem/observation-category|laboratory&date={gt|lt|ge|le}[date]{&date={gt|lt|ge|le}[date]&...}

    Example:

    1. GET [base]Observation?patient=555580&category=survey&date=ge2018-03-14T00:00:00Z

    Implementation Notes: Fetches a bundle of all Observation resources for the specified patient and date and a category code = laboratory (how to search by reference and how to search by token and how to search by date)

Optional Search Parameters:

The following search parameter combinations SHOULD be supported:

  1. SHOULD support searching using the combination of the patient and category and status search parameters:
    • including support for OR search on status (e.g.status={system|}[code],{system|}[code],...)

    GET [base]/Observation?patient={Type/}[id]&category=http://terminology.hl7.org/CodeSystem/observation-category|laboratory&status={system|}[code]{,{system|}[code],...}

    Example:

    1. GET [base]/Observation?patient=1134281&category=survey&status=final

    Implementation Notes: Fetches a bundle of all Observation resources for the specified patient and category = laboratory and status (how to search by reference and how to search by token)

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

    GET [base]/Observation?patient={Type/}[id]&category={system|}[code]&_lastUpdated={gt|lt|ge|le}[date]{&_lastUpdated={gt|lt|ge|le}[date]&...}

    Example:

    1. GET [base]Observation?patient=555580&survey&_lastUpdated=ge2024-01-01T00:00:00Z

    Implementation Notes: Fetches a bundle of all Observation resources for the specified patient and category and _lastUpdated. See the IE Core General Guidance page for Searching Using lastUpdated. (how to search by reference and how to search by token and how to search by date)

  3. SHOULD support searching using the combination of the patient and code and date search parameters:
    • including optional support for OR search on code (e.g.code={system|}[code],{system|}[code],...)
    • including support for these date comparators: gt,lt,ge,le
    • including optional support for AND search on date (e.g.date=[date]&date=[date]]&...)

    GET [base]/Observation?patient={Type/}[id]&code={system|}[code]{,{system|}[code],...}&date={gt|lt|ge|le}[date]{&date={gt|lt|ge|le}[date]&...}

    Example:

    1. GET [base]Observation?patient=555580&code=http://loinc.org|9271-8&date=ge2019-01-01T00:00:00Z

    Implementation Notes: Fetches a bundle of all Observation resources for the specified patient and date and report code(s). SHOULD support search by multiple report codes. (how to search by reference and how to search by token and how to search by date)
