By the end of next year, more than a third of U.S. employers will offer their workers the ability to receive health care remotely using emerging telemedicine solutions, according to a survey from Towers Watson, which finds companies are being driven to new technologies by a need for lower-cost treatment options. The firm predicts that telemedicine will help U.S. businesses save more than $6 billion in health care costs and eliminate the need for office visits in more than 14% of cases.
