emocha Mobile Health launched its video-based directly observed therapy application, miDOT, in Harris County, Texas. miDOT will be used to bridge the distance between healthcare workers and the tuberculosis (TB) patients that are dispersed across the nearly 1,800 square miles surrounding Houston, which has one of the nation’s highest Tuberculosis rates. The roll-out began in early February after emocha won a competitive bidding process based on a head-to-head pilot with competing technologies.
