Soon doctors will use a wristband to tell if they washed their hands properly.
A startup called intelligentM is developing the RFID-reading, motion sensing device, which vibrates when the wearer has scrubbed their hands sufficiently. If not, their activity will be logged and possibly passed on to their boss, who can monitor other employees wearing the band.
According to MIT Technology Review, some 100,000 people have died due to hospital infections, and many payers, including Medicare, refuse to reimburse hospitals for those illnesses. So as a result, there's a greater push to get doctors, nurses and technicians to wash well.
