description: A Sex Parameter for Clinical Use is a parameter that provides guidance on how a recipient should apply settings or reference ranges that are derived from observable information such as an organ inventory, recent hormone lab tests, genetic testing, menstrual status, obstetric history, etc.. This property is intended for use in clinical decision making, and indicates that treatment or diagnostic tests should consider best practices associated with the relevant reference population. When exchanging these concepts, refer to the guidance in the [Gender Harmony Implementation Guide](http://hl7.org/xprod/ig/uv/gender-harmony/). package_name: hl7.fhir.uv.extensions.r5 derivation: constraint name: PatSexParameterForClinicalUse type: Extension elements: extension: short: A context-specific sex parameter for clinical use type: Extension index: 0 slicing: slices: value: match: {} schema: short: A context-specific sex parameter for clinical use type: Extension _required: true index: 0 extensions: {} elements: extension: {index: 1} url: type: uri pattern: {type: Uri, value: value} index: 2 value: choices: [valueCodeableConcept] index: 4 valueCodeableConcept: {type: CodeableConcept, choiceOf: value, index: 5} required: [value, valueCodeableConcept] period: match: {} schema: type: Extension short: When the sex for clinical use applies index: 6 extensions: {} elements: extension: {index: 7} url: type: uri pattern: {type: Uri, value: period} index: 8 value: choices: [valuePeriod] index: 10 valuePeriod: {type: Period, choiceOf: value, index: 11} required: [valuePeriod, value] comment: match: {} schema: type: Extension short: Context about the sex parameter for clinical use index: 12 extensions: {} elements: extension: {index: 13} url: type: uri pattern: {type: Uri, value: comment} index: 14 value: choices: [valueString] index: 16 valueString: {type: string, choiceOf: value, index: 17} required: [valueString, value] supportingInfo: match: {} schema: type: Extension short: Source of the sex for clincal use index: 18 extensions: {} elements: extension: {index: 19} url: type: uri pattern: {type: Uri, value: supportingInfo} index: 20 value: choices: [valueCodeableReference] index: 22 valueCodeableReference: {type: CodeableReference, choiceOf: value, index: 23} required: [valueCodeableReference, value] url: pattern: {type: Uri, value: 'http://hl7.org/fhir/StructureDefinition/patient-sexParameterForClinicalUse'} index: 24 value: choices: [] index: 26 package_version: 1.0.0 extensions: value: url: null short: A context-specific sex parameter for clinical use type: Extension _required: true index: 0 extensions: {} elements: extension: {index: 1} url: type: uri pattern: {type: Uri, value: value} index: 2 value: choices: [valueCodeableConcept] index: 4 valueCodeableConcept: {type: CodeableConcept, choiceOf: value, index: 5} required: [value, valueCodeableConcept] period: url: null type: Extension short: When the sex for clinical use applies index: 6 extensions: {} elements: extension: {index: 7} url: type: uri pattern: {type: Uri, value: period} index: 8 value: choices: [valuePeriod] index: 10 valuePeriod: {type: Period, choiceOf: value, index: 11} required: [valuePeriod, value] comment: url: null type: Extension short: Context about the sex parameter for clinical use index: 12 extensions: {} elements: extension: {index: 13} url: type: uri pattern: {type: Uri, value: comment} index: 14 value: choices: [valueString] index: 16 valueString: {type: string, choiceOf: value, index: 17} required: [valueString, value] supportingInfo: url: null type: Extension short: Source of the sex for clincal use index: 18 extensions: {} elements: extension: {index: 19} url: type: uri pattern: {type: Uri, value: supportingInfo} index: 20 value: choices: [valueCodeableReference] index: 22 valueCodeableReference: {type: CodeableReference, choiceOf: value, index: 23} required: [valueCodeableReference, value] class: extension kind: complex-type url: http://hl7.org/fhir/StructureDefinition/patient-sexParameterForClinicalUse base: http://hl7.org/fhir/StructureDefinition/Extension version: 1.0.0 required: [extension]
