Patient data added to Whiteboard is only visible to the user who created it.
Sharing is how you control is visible to others.
Shares are typically between two users and are only active when both parties accept.
A share can be cancelled at any time.
A share is only for a single patient.
You will get notified when you receive a new share or when your share has been accepted.
Both parties in the share can choose the individual data items (Progress Notes, History, Prescriptions etc.) that they wish to share.
Shares can also be setup to automatically add new data items to an existing share.
