description: The PDQm Match Input Parameters Profile describes the Parameters Resource that is to be posted to the $match endpoint when invoking ITI-119.\nThis profile is consistent with the exceptions of the [Patient-match operation in FHIR core](http://hl7.org/fhir/R4/patient-operation-match.html),\nexcept the input resource SHALL be an instance of the [PDQm Patient Profile for $match Input](StructureDefinition-CHPDQmMatchInput.html).\n\nNote that the only REQUIRED parameter is the Patient Resource. When only the Patient is supplied, it can be POSTed directly to the $match endpoint\nwithout being wrapped in a Parameters Resource, as long as it conforms to the [PDQm Patient Profile for $match Input](StructureDefinition-CHPDQmMatchInput.html). package_name: ch.fhir.ig.ch derivation: constraint name: CHPDQmMatchParametersIn type: Parameters elements: parameter: index: 0 slicing: slices: resource: match: {} schema: index: 0 elements: resource: {type: Patient, index: 1} package_version: epr-fhir-4.0.1 class: profile kind: resource url: http://fhir.ch/ig/ch-epr-fhir/StructureDefinition/CHPDQmMatchParametersIn base: https://profiles.ihe.net/ITI/PDQm/StructureDefinition/IHE.PDQm.MatchParametersIn version: 4.0.1
