Primary care doctors in England have been told by the National Institute for Health and Care Excellence (NICE) to prescribe a digital therapeutic instead of sleeping tablets for patients suffering with insomnia. Sleepio, an app developed by London-based Big Health Ltd. that uses an algorithm to provide personalized cognitive behavioral therapy (CBT), could benefit up to 800,000 people, according to NICE. It is recommending use of the app as an effective alternative to drugs such as zolpidem and zopiclone, after weighing evidence from 28 studies, including 12 randomized controlled trials.
