### Sending a CDA Document

#### Scenario

The "Anytown General Hospital" needs to send an ITK Discharge Summary for the now completed in-patient stay for Mrs. Smith. Mrs. Smith has been discharged from the care of the Oncology team in the hospital. The Discharge Summary needs to be delivered to Mrs. Smith's General Practice "The Surgery, Townville", and in particular to her regular General Practitioner Dr. Brown. It is the hospital's practice to request both an infrastructure acknowledgement and business acknowledgement from GP practices to show that Discharge Summaries have been received into the GP practice system. Metadata is also generated for the correspondence.

#### Codes used in this example

- Anytown General Hospital has an Organisation Data Service (ODS) code of "R59"
- The Surgery, Townville has an ODS code of "Y88764"
- Dr. Brown has a General Medical Council code of "G1234567"
- Mrs. Smith's NHS Number is "2345678901"
- The discharge report interaction id is "urn:nhs-itk:interaction:primaryRecipientDischargeReport-v1-0"

#### Acknowledgement related handling specifications

- urn:nhs-itk:ns:201005:infackrequested set to "true"
- urn:nhs-itk:ns:201005:ackrequested set to "true"
- urn:nhs-itk:ns:201005:busresponserequested set to "false"

#### Creating the distribution envelope for a CDA document transmission requiring an acknowledgement

The CDA document has been created by an author working for the Oncology team for Anytown General Hospital, it has been attested to, and is ready for transmission to Mrs. Smith's General Practice (in particular Dr. Brown).

#### Completing the Distribution Envelope
