Abstract
A system for early warning of non-compliance with an established workflow in a work area includes a radio frequency (RF) sensor configured to detect each of a plurality of RF signals located within the work area, and a monitoring system operably connected to the RF sensor. The monitoring system is configured to compare a temporal sequence of detected RF signals to a predetermined temporal sequence of the RF signals associated with the established workflow, and to determine whether a warning condition exists based on the comparison. The RF signals can be emitted by RFID tags within the work area, such as a patient room of a healthcare provider, and the RFID tags may be associated with a hand sanitizing station, an intravenous solution dispenser, and a healthcare provider staff member, each of which play a role in reducing the incidence of hospital-acquired infections through compliance with corresponding patient safety protocols.
