Attributes
| Attribute | Type | Multiplicity | Attribute note |
|---|---|---|---|
| Encounter Identifier | Identifier | 0..1 | |
| Encounter Category Code | Codeable Concept | 0..1 | Uniquely specifies the category (class) of an encounter (e.g., emergency, ambulatory, inpatient acute/non-acute).
Value Set: To be developed. |
| Encounter Type Code | Codeable Concept | 0..1 | Uniquely specifies the specific type of care or service provided during the encounter (e.g., prenatal visit, diabetic foot care visit, cancer screening).
Value Set: To be developed. |
| Encounter Priority Code | Codeable Concept | 0..1 | |
| Encounter Mode Code | Codeable Concept | 0..* | Uniquely specifies the possible method(s) of contact with the health care provider(s) available in the encounter to its participants (e.g., in-person, email, text, telephone).
Synonym of "mode" in this context: modality, visit modality.
Value Set: https://fhir.infoway-inforoute.ca/ValueSet/visitmodalitycode |
| Encounter Creation Date Time | Date Time | 0..1 | The date and, if known, the time the encounter was created.
Note: This may be different from appointment creation date time. For instance, as in some systems, the following sequence of consecutive actions may apply:
1) Patient goes to see their endocrinologist and has to come back for a reassessment in 2 weeks.
2) On leaving this consultation they create an appointment in 2 weeks time.
3) Patient calls a few days later having to cancel the appointment and is able to push the appointment a few days. The encounter stays the same (e.g., 2 week follow-up), with the same creation date-time as that of the previous appointment, but that appointment is cancelled and new one is created for the encounter. Hence, at this stage, encounter creation date-time is different from appointment creation date-time. |
| Encounter Period | Period | 0..1 | The date and, if known, the time when the encounter began and when it was administratively ended according to local workflow or policy. |
