## Resource Profile: US Core QuestionnaireResponse Profile

Official URL: http://hl7.org/fhir/us/core/StructureDefinition/us-core-questionnaireresponse | Version: 9.0.0
Standards status: Trial-use | Maturity Level: 3 | Computable Name: USCoreQuestionnaireResponseProfile
Other Identifiers: OID:2.16.840.1.113883.4.642.40.2.42.56

The US Core QuestionnaireResponse Profile inherits from the Structured Data Capture (SDC) Questionnaire Response Profile. This profile sets minimum expectations for the QuestionnaireResponse resource to record, search, and fetch the responses to form/survey and assessment tools such as the Protocol for Responding to and Assessing Patients\u2019 Assets, Risks, and Experiences (PRAPARE) Survey. It specifies which core additional elements, extensions, vocabularies, and value sets SHALL be present and constrains how the elements are used. 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.

Example Usage Scenarios:

The following are example usage scenarios for this profile:

- Query for survey screening results for a patient.
- Record or update screening results belonging to a Patient

### Mandatory and Must Support Data Elements

In addition to the Mandatory and Must Support data elements in the SDC QuestionnaireResponse Profile, 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. Note that the Key Elements Table view aggregates all the Must Support elements between this profile and its parent profiles.

Each QuestionnaireResponse Must Have:

1. a reference back to the assessment upon which it is based
2. a status
3. a patient
4. the date the answers were gathered

Each QuestionnaireResponse Must Support:

1. a practitioner who recorded the answers1
2. the questions and decimal, string, and coded answers
   - each question must have an identifier pointing to the question

1 see guidance below

### Profile Specific Implementation Guidance

This section provides detailed implementation guidance for the US Core Profile to support implementation and certification.

- The SDC profile (from which this profile is derived) focuses on the constraints appropriate to capturing the "answer(s)" to a FHIR Questionnaire and demands that the Questionnaire's canonical URL be specified. If the QuestionnaireResponse is based on a non-FHIR form:
  1. Construct a FHIR Questionnaire representing at least the relevant metadata (in other words, the questions may be omitted).
  2. Communicates the identifier of the non-FHIR form instead of the canonical URI using the US Core Extension Questionnaire URI extension.
- See the Screening and Assessments guidance page for how this profile or Observations can represent SDOH assessments.
- QuestionnaireResponse can be searched using the standard FHIR RESTful API search parameters. Example searches are shown in the Quick Start section below. Although search chains through the associated Questionnaire can be used to query QuestionnaireResponse by item, individual responses are not directly searchable in QuestionnaireResponse. To search directly for individual responses, they must be "parsed" into a searchable form - i.e., to a local FHIR or non-FHIR data store such as a database or FHIR Observations.
- The basic workflow for creating, discovering, retrieving, and data-extracting FHIR Questionnaire and QuestionnaireResponse is thoroughly documented in the Structured Data Capture (SDC) implementation guide.

- 1The profile elements `QuestionnaireResponse.author and QuestionnaireResponse.source` communicate the individual level provenance author data corresponding to the U.S. Core Data for Interoperability (USCDI) Provenance Author Data Elements.

Usages:

- Refer to this Profile: US Core Observation Screening Assessment Profile and US Core Simple Observation Profile
- Examples for this Profile: QuestionnaireResponse/AUDIT-C, QuestionnaireResponse/TAPS, QuestionnaireResponse/exercise-vital-sign, QuestionnaireResponse/glascow-coma-score... Show 3 more, QuestionnaireResponse/hunger-vital-sign-example, QuestionnaireResponse/phq-9-example and QuestionnaireResponse/prapare-example
- CapabilityStatements using this Profile: US Core Client CapabilityStatement and US Core Server CapabilityStatement

### 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.

- See the Scopes Format section for a description of the SMART scopes syntax.
- See the Search Syntax section for a description of the US 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.

#### US Core Scopes

Servers providing access to completed questionnnaire, survey and assessement data SHALL support these US Core SMART Scopes:

- resource level scopes: `<patient|user|system>/QuestionnaireResponse.rs` §

#### Mandatory Search Parameters:

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

1. SHALL support both read QuestionnaireResponse by `id` AND QuestionnaireResponse search using the _id search parameter

   `GET [base]/QuestionnaireResponse?_id=[id]' or 'GET [base]/QuestionnaireResponse/[id]`

   Examples:

   > 1. GET [base]/!QuestionnaireResponse/AHC-HRSN-screening-example

   > 2. GET [base]/!QuestionnaireResponse/?_id=AHC-HRSN-screening-example

   Implementation Notes: Fetches a US Core QuestionnaireResponse Profile resource or a search Bundle containing a US Core QuestionnaireResponse Profile resource matching the id (see Parameters for all resources).

2. SHALL support searching for all questionnaireresponses for a patient using the patient search parameter

   `GET [base]/QuestionnaireResponse?patient={Patient/}[id]`

   Example:

   > 1. GET [base]/QuestionnaireResponse?patient=Patient/1137192&

   Implementation Notes: Fetches a bundle of all US Core QuestionnaireResponse Profile resources for the specified patient ( see how to search by reference).

#### Optional Search Parameters:

The following search parameters and search parameter combinations SHOULD be supported

1. SHOULD combo description field using the combination of the patient and status search parameters

   - Including support OR search on `status` (e.g.`status={system|}[code],{system|}[code],...`)

   `GET [base]/QuestionnaireResponse?patient={Patient/}[id]&status={system|}[search_code]{,{system|}[code],...}`

   Example:

   > 1. GET [base]/QuestionnaireResponse?patient=Patient/1137192&status=completed

   Implementation Notes: Fetches a bundle of all US Core QuestionnaireResponse Profile resources for the specified patient and status ( see how to search by reference and how to search by token).

2. SHOULD combo description field using the combination of the patient and authored search parameters

   - Including optional support for AND search on `authored` (e.g.`authored=[date]&authored=[date]&...`)

   - Including support for these `authored` comparators: "gt", "lt", "ge", "le"

   `GET [base]/QuestionnaireResponse?patient={Patient/}[id]&authored={gt|lt|ge|le}[dateTime]{&date={gt|lt|ge|le}[dateTime]&...}`

   Example:

   > 1. GET [base]/QuestionnaireResponse?patient=Patient/1137192&date=ge2021

   Implementation Notes: Fetches a bundle of all US Core QuestionnaireResponse Profile resources for the specified patient and date ( see how to search by reference).

3. SHOULD combo description field using the combination of the patient and questionnaire search parameters

   `GET [base]/QuestionnaireResponse?patient={Patient/}[id]&questionnaire={Type/}[id]`

   Example:

   > 1. GET [base]/QuestionnaireResponse?patient=Patient/1137192&questionnaire=http://hl7.org/fhir/us/sdoh-clinicalcare/Questionnaire/SDOHCC-QuestionnaireHungerVitalSign

   Implementation Notes: Fetches a bundle of all US Core QuestionnaireResponse Profile resources for the specified patient that have been completed against a specified form. ( see how to search by reference).

#### Searching QuestionnaireResponse by Context

Searching a patient's QuestionnaireResponses by specific context such as those defined in US Core Category can be achieved by querying the metadata on the associated Questionnaire. Specifically, `Questionnaire.useContext` with a code="focus" and value of "sdoh"/"functionalStatus"/etc. could be accomplished using a chained search:

`GET [base]/QuestionnaireResponse?subject=Patient/123&questionnaire.context-type-value=focus$sdoh`
