Currently, significant healthcare support staff time is spent trying to fill cancelled shifts. This project will develop a mobile and desktop app which notifies the appropriate Environmental Services Staff of available shifts. An algorithm which accounts for seniority is used to select the order in which staff will be notified. ShiftLink will refine features to meet the needs of Markham Stouffville Hospital support staff. This pilot will provide proof of concept leading to the expansion of the program to other user groups at MSH and other healthcare organizations.
