Abstract: The scheduler matches staffing requirements with qualified healthcare workers, each having a GPS cell phone. The workers have an online UPP and a calendar with OPEN/CLOSED shift dates/times. Once matched to a staffing requirement, workers are notified and within 15 minutes they must respond. Non-responses reduce the selection ranking of workers. For shift-assigned workers, the system gathers worker GPS data prior to the shift-time. Transit time or distance is monitored from the worker geolocation to the facility. If dynamic thresholds are exceeded, alerts are generated to the worker and the manager. The facility sends a cancel, hold open or replace command for the shift. If replace, the system repeats a worker identify, match, notify, accepting response, prioritize, and notify selected worker for the shift.
