A Florida hospital says electronic tracking of nursing personnel is helping it refine their workflow and work habits and lay the groundwork to replace the obsolete "midnight census" method of determining staffing requirements. Florida Hospital Celebration Health is using Real Time Locating System (RTLS) tags and sensors from Stanley Healthcare, a division of Stanley Black & Decker that provides inventory, security, and safety products for the healthcare industry. Like GPS, RTLS is location tracking technology, but with greater precision for tracking movements within a building rather than across the globe.
