description: A stoma is an unnatural, surgically created opening connecting a body cavity with the outside world. A stoma is created e.g. as an exit opening for feces or urine in the event that they cannot leave the body naturally. In the case of a tracheostomy, the stoma is intended to facilitate breathing if that is no longer possible via the oral, nasal and throat cavity. package_name: nictiz.fhir.nl.r4.zib2020 derivation: constraint name: ZibStoma abstract: true type: Condition elements: category: pattern: type: CodeableConcept value: coding: - {code: '245857005', system: 'http://snomed.info/sct'} index: 0 code: short: StomaType binding: {strength: extensible, valueSet: 'http://decor.nictiz.nl/fhir/ValueSet/2.16.840.1.113883.2.4.3.11.60.40.2.5.2.1--20200901000000'} index: 1 bodySite: {type: CodeableConcept, short: Location / AnatomicalLocation, index: 2} onset: short: CreationDate choices: [onsetDateTime] index: 7 slicing: slices: onsetDateTime: match: {} schema: short: CreationDate choices: [onsetDateTime] index: 7 onsetDateTime: short: CreationDate type: dateTime choiceOf: onset index: 8 slicing: slices: onsetDateTime: match: {} schema: {short: CreationDate, type: dateTime, choiceOf: onset, index: 8} note: index: 9 elements: text: {short: Comment, index: 10} package_version: 0.9.0-beta.1 class: profile kind: resource url: http://nictiz.nl/fhir/StructureDefinition/zib-Stoma base: http://hl7.org/fhir/StructureDefinition/Condition version: null required: [category, code]
