The EPS SOS member calls or writes to your organization. 2. The assistant asks for the EPS SOS order and authorization before offering a slot. 3. It checks availability in Microsoft Outlook and creates the appointment as an event on the clinician's calendar. 4. If the patient reschedules, it moves it in Microsoft Outlook and lets your team know. ## What each one is - Health insurer (EPS) in the contributory and subsidized regimes ### EPS SOS Servicio Occidental de Salud EPS S.A.
