Are doctors' hands clean? This wristband knows

MIT Technology Review, March 27, 2013

A startup called IntelligentM wants to make hospitals healthier by encouraging workers to clean their hands properly. Its solution is a bracelet that vibrates when the wearer has scrubbed sufficiently, giving employees a way to check their habits and letting employers know who is and isn't doing things right. Some 100,000 people a year in the United States alone die because of infections that arise from hospital visits, according to the Centers for Disease Control and Prevention, and a lot of these infections occur because doctors, nurses, and technicians don't wash well enough. The problem has garnered more attention lately, in part because Medicare and other payers have stopped reimbursing hospitals for expenses related to treating hospital-acquired infections.
