One of the requests from the user study indicated that there is an issue with the workflow when finishing the scheduling of a new appointment:
"As you are scheduling a new appointment and confirming it the module redirects to the appointments list page and closes the previous page, and thus you need to write down manually the appointment details even before it was saved"
Thus, I suggest we should make some sort of confirmation before saving the appointment that shows the full appointment details.
