description: The US Core Observation Sexual Orientation Profile inherits from the FHIR [Observation](https://hl7.org/fhir/R4/observation.html) resource; refer to refer to it for scope and usage definitions. This Profile sets minimum expectations for the Observation resource to record, search, and fetch sexual orientation observations associated with a patient. 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. package_name: hl7.fhir.us.core derivation: constraint name: USCoreObservationSexualOrientationProfile type: Observation elements: effectiveDateTime: {type: dateTime, mustSupport: true, choiceOf: effective, index: 5} status: binding: {strength: required, valueSet: 'http://hl7.org/fhir/ValueSet/observation-status'} mustSupport: true index: 0 effective: mustSupport: true choices: [effectiveDateTime, effectivePeriod, effectiveTiming, effectiveInstant] index: 4 code: short: Sexual Orientation mustSupport: true pattern: type: CodeableConcept value: coding: - {code: 76690-7, system: 'http://loinc.org'} type: CodeableConcept index: 1 effectiveTiming: {type: Timing, mustSupport: true, choiceOf: effective, index: 7} valueCodeableConcept: short: Sexual Orientation binding: {strength: extensible, valueSet: 'http://cts.nlm.nih.gov/fhir/ValueSet/2.16.840.1.113762.1.4.1240.11', bindingName: SexualOrientation} mustSupport: true index: 9 effectiveInstant: {type: instant, mustSupport: true, choiceOf: effective, index: 8} subject: type: Reference mustSupport: true refers: ['http://hl7.org/fhir/us/core/StructureDefinition/us-core-patient'] index: 2 effectivePeriod: {type: Period, mustSupport: true, choiceOf: effective, index: 6} package_version: 8.0.0 class: profile kind: resource url: http://hl7.org/fhir/us/core/StructureDefinition/us-core-observation-sexual-orientation base: http://hl7.org/fhir/StructureDefinition/Observation version: 8.0.0 required: [subject]
