ContactRank

The SDK supports the Contact Rank extension on the Patient.ContactComponent type used in the Patient.contact collection within the Patient resource.

URL Definition​

using FhirUkCore.Uris;

String extensionUrl = UkCoreUris.ExtensionContactRank;

HasContactRank​

To test whether the extension has been applied to a Patient.ContactComponent type, the HasContactRank method can be used. This returns a boolean.

using Hl7.Fhir.Model;

Boolean existsContactRank = pat.contact[0];

SetContactRank​

To set the Contact Rank for a Patient.ContactComponent type, the SetContactRank method can be used.
The actual rank to be applied must be specified using a FHIR PositiveInt datatype.

 var testContact = new Patient.ContactComponent()
 {
     Name = new HumanName()
     { Text = "A Test Name" }
 };

 testContact.SetContactRank(new PositiveInt(2));

GetContactRank​

To retrieve the Contact Rank from a Patient.ContactComponent type, the GetContactRank method can be used.
This will return a Contact Rank as a PositiveInt datatype. If the extension has not been set a null will be returned.

using Hl7.Fhir.Model;

PositiveInt rank = pat.contact[0].GetContactRank();
