Scaling Up mHealth: Where Is the Evidence?
Essay on mobile Health
PLOS Medicine "Despite hundreds of mHealth pilot studies, there has been insufficient programmatic evidence to inform implementation and scale-up of mHealth. We discuss what constitutes appropriate research evidence to inform scale up. Potential innovative research designs such as multi-factorial strategies, randomized controlled trials, and data farming may provide this evidence base. We make a number of recommendations about evidence, interoperability, and the role of governments, private enterprise, and researchers in relation to the scale up of mHealth."
