Emssanar EPS members' appointments, in Microsoft Outlook. With Arbol, with no manual copying.
How it works
The Emssanar EPS member calls or writes to your organization.
The assistant asks for the Emssanar EPS order and authorization before offering a slot.
It checks availability in Microsoft Outlook and creates the appointment as an event on the clinician's calendar.
If the patient reschedules, it moves it in Microsoft Outlook and lets your team know.
