description: This profile represents the constraints applied to the MedicationStatement resource by the PS-CA project to represent a record of a medication statement in the patient summary. It is informed by the constraints of the [MedicationStatement IPS-UV profile](http://hl7.org/fhir/uv/ips/StructureDefinition-MedicationStatement-uv-ips.html) and the [Canadian Baseline Profile](http://build.fhir.org/ig/HL7-Canada/ca-baseline/branches/master/StructureDefinition-profile-medicationstatement.html) to allow for cross-border and cross-jurisdiction sharing of Medication Summary information. package_name: ca.infoway.io.psca derivation: constraint name: MedicationStatementPSCA type: MedicationStatement elements: dosage: mustSupport: true index: 12 elements: text: {mustSupport: true, index: 13} timing: {index: 14} route: type: CodeableConcept binding: {strength: preferred, valueSet: 'https://fhir.infoway-inforoute.ca/ValueSet/routeofadministration'} index: 15 medicationCodeableConcept: {type: CodeableConcept, mustSupport: true, choiceOf: medication, index: 5} effective[x]: extensions: data-absent-reason: {url: 'http://hl7.org/fhir/StructureDefinition/data-absent-reason', max: 1, short: 'effective[x] absence reason', type: Extension, mustSupport: true, index: 11} elements: extension: index: 10 slicing: rules: open description: Extensions are always sliced by (at least) url discriminator: - {path: url, type: value} min: null slices: data-absent-reason: match: {url: null} schema: {short: 'effective[x] absence reason', type: Extension, mustSupport: true, url: 'http://hl7.org/fhir/StructureDefinition/data-absent-reason', index: 11} max: 1 extension: type: Extension short: Extension for representing rendered dosage instruction. url: http://prescribeit.ca/fhir/StructureDefinition/ext-rendered-dosage-instruction index: 0 slicing: slices: RenderedDosageInstruction: match: {} schema: {type: Extension, short: Extension for representing rendered dosage instruction., url: 'http://prescribeit.ca/fhir/StructureDefinition/ext-rendered-dosage-instruction', index: 0} max: 1 status: {mustSupport: true, index: 1} effective: mustSupport: true choices: [] index: 9 medicationReference: type: Reference mustSupport: true choiceOf: medication refers: ['http://fhir.infoway-inforoute.ca/io/psca/StructureDefinition/medication-ca-ps'] index: 4 subject: type: Reference mustSupport: true refers: ['http://fhir.infoway-inforoute.ca/io/psca/StructureDefinition/patient-ca-ps'] index: 6 elements: reference: {mustSupport: true, index: 7} required: [reference] medication: mustSupport: true choices: [medicationReference, medicationCodeableConcept] index: 3 package_version: 2.0.2-DFT-Ballot extensions: RenderedDosageInstruction: {url: 'http://prescribeit.ca/fhir/StructureDefinition/ext-rendered-dosage-instruction', max: 1, type: Extension, short: Extension for representing rendered dosage instruction., index: 0} class: profile kind: resource url: http://fhir.infoway-inforoute.ca/io/psca/StructureDefinition/medicationstatement-ca-ps base: http://hl7.org/fhir/StructureDefinition/MedicationStatement version: null required: [effective]
