Medication on discharge is referenced, never copied: those MedicationRequests already exist on the server -- the form picks them from it -- so they become section entries rather than new resources. The follow-up is intent `plan` rather than an Appointment because the form captures it as free text with no date to book against; give the item a date and an Appointment becomes the truer target. The Encounter is deliberately untouched: closing the stay -- Encounter.status and the discharge disposition -- belongs to the EMR\\'s discharge workflow, which knows about bed release, billing and the actual moment the patient left. Writing a note is not the same event as being discharged, and a map that conflated them would close stays early.'\r\n\r\nuses "http://hl7.org/fhir/StructureDefinition/QuestionnaireResponse" alias QR as source\r\nuses "http://hl7.org/fhir/StructureDefinition/Bundle" alias Bundle as target\r\nuses "http://hl7.org/fhir/StructureDefinition/Composition" alias Composition as target\r\nuses "http://hl7.org/fhir/StructureDefinition/ServiceRequest" alias ServiceRequest as target\r\n\r\ngroup ExtractInpatientDischargeNote(source qr : QR, target bundle : Bundle) {\r\n qr -> bundle.type = 'transaction' "setBundleType";\r\n qr -> bundle.entry as entry, entry.resource = create('Composition') as comp then {\r\n qr -> comp, entry then BuildNoteBase(qr, comp, entry) "noteBase";\r\n qr -> comp.name = 'InpatientDischargeNote' "noteName";\r\n qr -> comp.title = 'Discharge note' "noteTitle";\r\n qr -> comp.type as ty then {\r\n qr -> ty.coding as sghi then {\r\n qr -> sghi.system = 'https://fhir.slade360.co.ke/fhir/CodeSystem/inpatient-document-type-codesystem' "sghiSystem";\r\n qr -> sghi.code = 'discharge-note' "sghiCode";\r\n qr -> sghi.display = 'Discharge note' "sghiDisplay";\r\n } "sghiCoding";\r\n qr -> ty.coding as loinc then {\r\n qr -> loinc.system = 'http://loinc.org' "loincSystem";\r\n qr -> loinc.code = '18842-5' "loincCode";\r\n qr -> loinc.display = 'Discharge summary' "loincDisplay";\r\n } "loincCoding";\r\n qr -> ty.text = 'Discharge summary' "typeText";\r\n } "noteType";\r\n qr.item as it where ((linkId = 'summary') and answer.value.exists()) -> comp.section as sec then {\r\n it -> sec.title = 'Admission summary' "summaryTitle";\r\n it -> sec then AddSectionText(it, sec) "summaryText";\r\n } "summaryRule";\r\n // One section, one entry per medication.
