Here, you can invite a new patient to join a study. If the patient already exists within Health Storylines, then you do not need to fill out any additional details and may simply send the invitation.

If, however, the patient is not already in Health Storylines, then an additional section will appear, which will prompt the admin to add additional details regarding the patient, including what Group they are in (which can be configured in the Manage Groups tab), and other personal information such as their name, gender, etc.
