Why can’t hospitals get health care workers to wash their hands?
Hospitals in the United States enjoy access to running water. Virtually all of them have alcohol-rub dispensers, hundreds of them, in the hallways. Using one takes a few seconds. Yet health care workers fail to wash hands a good percentage of the times they should. Doctors are particularly bad.
A health care worker’s hands are the main route infections take to move from one patient to another. One recent study of several intensive care units — where the patients most vulnerable to infection reside — showed that hands were washed on only one quarter of the necessary occasions....
... Enter technology. In the last year or two, several new ways to promote hand-washing – all things that beep – have made their debut: HyGreen, BioVigil, Patient Care Technology System’s Amelior 360 and Proventix’s nGage are some of them, but there are others. Some are spinoffs of systems widely used to track hospital equipment (this is how hospitals can find a wheelchair when it is needed). All employ new technology that can detect alcohol — which in hospitals is a component not only of rubbing gel but also soap.
They work like this: every health care worker wears an electronic badge. When she washes her hands or uses alcohol rub, a sensor at the sink or dispenser or her own badge smells the alcohol and registers that she has washed her hands. Another sensor near the patient detects when her badge enters a room or the perimeter around a patient that the hospital sets. If that badge shows that her hands were recently washed, it displays a green light or something else the patient can see. If she hasn’t washed, her hands, the badge says so and emits a signal to remind her to do so. The sensor also sends this information to a central data base. Information about the hand-washing practices of a particular unit, shift or individual is instantly available....
