A service provider system 110 operates to receive and store initial patient vital sign information, and to use this vital sign information to assign an initial queue position to the patient. The patient wears a mobile vital sign monitoring device that detects vital patient sign information and periodically sends this information to the system 110, which uses the current and past vital sign information to determine whether the patient vital signs are within an acceptable clinical range, and if not, the system 110 operates to modify the position of the patient within the queue.
