The goal is to display the MRN on the rapid registration once a patient is looked up, like this:

1) Add the MRN field to the rapid registration form

      - Using passagepoint's powerful screen policy, edit the Rapid Registration form

- Turn UniqueLabel's visible property to true.

- Change Lable Text to "MRN" then hit your enter key. Label will now read "MRN"

Do the same thing for the UniqueId field:

Now save by clicking on the save button at the top left.

2) Map the HL7 MRN field to passagepoint's uniqueId fiel

Add a new rule in Home > configure > Acitions under HL7 integrations exactly as below:

path to the field:    /.PID-3-1

Regular Expressions:   .*

Action:    Set attribute

Label:  _map.person.uniqueId
