The US Core Care Experience Preference Profile inherits from the FHIR [Observation](https://hl7.org/fhir/R4/observation.html) resource; refer to it for scope and usage definitions. This profile provides guidance on how to record a care experience preference expressed by the patient regarding their care and treatment. Examples include, but are not limited to, religious preferences, dislikes and fears, preferred place for birth, preferred pharmacy, and thoughts and feelings to be shared. This profile does not represent an actual order, but it can guide caregivers and medical personnel about what is important for the person. This profile sets minimum expectations for the Observation resource to record, search, and fetch for a patient care experience preferences. It 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. 

**Example Usage Scenarios:**

The following are example usage scenarios for this profile:

* Query for a patient's care experience preferences.
* [Record or update](us-core-roadmap.md#future-candidate-requirements-under-consideration) clinical observations or assessments about a patient's care experience preferences.

### Mandatory and Must Support Data Elements

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

**Each Observation Must Have:**

1. a status
1. a fixed code for care experience preference
1. a patient

**Each Observation Must Support:**

1. a category code of "care-experience-preference"
1. a time indicating when the preference was made
1. care experience preference value

**Additional USCDI Requirements:**

These [Additional USCDI Requirements](must-support.md#additional-uscdi-requirements) elements are not Mandatory or Must Support but are required for ONC Health IT certification testing and are included in the formal definition of the profile and the Observation examples.

### Profile Specific Implementation Guidance

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

* Care experience preferences expressed by a patient might be documented in narrative (text) form or the result of selecting from a list of options provided by the content creator/implementer.
* The context or precondition of a patient's preference **SHOULD** be supplied in: 
* the `Observation.valueString` (for example, "If this [health scenario] were to occur, …”) or
* an extension such as the PACIO Advance Directive Interoperability Implementation Guide's [Enclosed Precondition Extension](http://hl7.org/fhir/us/pacio-adi/StructureDefinition/adi-enclosedPrecondition-extension).[§](requirements.md#CONF-0422)
 
* A code system value **SHOULD** be supplied for each additional code.[§](requirements.md#CONF-0420)

* 1The profile elements `Observation.performer and Observation.device` communicate the [individual level provenance](basic-provenance.md#individual-level-provenance) author data corresponding to the U.S. Core Data for Interoperability (USCDI) Provenance Author Data Elements.

**Usages:**

* Examples for this Profile: [Observation/care-experience-preference](Observation-care-experience-preference.md)
* CapabilityStatements using this Profile: [US Core Client CapabilityStatement](CapabilityStatement-us-core-client.md) and [US Core Server CapabilityStatement](CapabilityStatement-us-core-server.md)

### 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](CapabilityStatement-us-core-server.md) for a complete list of supported RESTful interactions for this IG.

* See the [Scopes Format](scopes.md#scopes-format) section for a description of the SMART scopes syntax.
* See the [Search Syntax](general-guidance.md#search-syntax) section for a description of the US Core search syntax.
* See the [General Requirements](general-requirements.md) section for additional rules and expectations when a Server requires status parameters.
* See the [General Guidance](general-guidance.md) section for additional guidance on searching for multiple patients.

#### US Core Scopes

Servers providing access to care experience preference data **SHALL** support these [US Core SMART Scopes](scopes.md#smart-scopes):

* [resource level scopes](http://hl7.org/fhir/smart-app-launch/STU2.2/scopes-and-launch-context.html#scopes-for-requesting-clinical-data): `<patient|user|system>/Observation.rs` [§](requirements.md#CONF-0145)

Servers providing access to care experience preference data **MAY** support these [US Core SMART Scopes](scopes.md#smart-scopes):

* [granular scopes](http://hl7.org/fhir/smart-app-launch/STU2.2/scopes-and-launch-context.html#finer-grained-resource-constraints-using-search-parameters): `<patient|user|system>/Observation.rs?category=http://hl7.org/fhir/us/core/CodeSystem/us-core-category|care-experience-preference` [§][]

-------

#### Mandatory Search Parameters:

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

1. **SHALL** support searching for all Observations using the combination of the [patient](SearchParameter-us-core-observation-patient.md) and [category](SearchParameter-us-core-observation-category.md) search parameters`GET [base]/Observation?patient={Patient/}[id]&category={system|}[search_code]`Example:
> 
1. GET [base]/Observation?patient=Patient/1137192&category=care-experience-preference

**Implementation Notes**: Fetches a bundle of all US Core Care Experience Preference Profile resources for the specified patient and a category code = "care-experience-preference" ( see [how to search by reference](http://hl7.org/fhir/R4/search.html#reference) and [how to search by token](http://hl7.org/fhir/R4/search.html#token)).
1. **SHALL** support searching for all Observations by code using the combination of the [patient](SearchParameter-us-core-observation-patient.md) and [code](SearchParameter-us-core-observation-code.md) search parameters
