OnCall Wiki Homepage


OnCall is an application that provides on-call scheduling for clinical staff, location of staff that are on-call in real time, and real time contact/communication capability for those clinicians on-call at any given moment for the hospital.

OnCall allows not only administrators to plan their staffing of on-call rotations, but also allows staff to trade on-call schedules and cover for each other through interactions between staff members within the application. In an emergency OnCall can nofify the user which staff are the closest and allow the user to choose who to contact.
