I can already hear the clamor for a home unit, with sensors conveniently close to the kitchen table. Your New BFF will be telling you to wash your hands….

The trademarked system, called HyGreen, logs, down to the second, the frequency of hand cleaning and contact with patients in a database that clinical supervisors can review immediately.

This is the first system that enables real-time monitoring of hand washing.

“This isn’t big brother, this is just another tool,” said Richard J. Melker, M.D., Ph.D., a UF College of Medicine anesthesiology professor who developed the technology ……

Here’s how it works: The health-care worker squirts sanitizer gel or soap into his or her hand before passing it under a wall-mounted sensor. A wireless signal from a badge worn by the worker activates a green light on the hand-washing sensor. When the worker enters a patient room, a monitor near the bed detects the status of the badge, and flashes green if the person has clean hands. If the person has not washed, or too much time has passed between washing and approaching the patient, the badge will give a gentle “reminder” vibration.

“I do wash my hands more often,” said nurse Carrie McGirr, R.N., who volunteered to help test the HyGreen system. “It’s a fairly simple process to learn.”
