Can novel health applications in developing countries spark health innovation in the United States? Massive experimentation in mobile and interactive health is taking place overseas, often targeting poor populations in poor countries. Consider several current examples: 1) a smart card enabled health savings scheme for uninsured mothers-to-be; 2) a crowdsourcing application to identify medicine stockouts in real-time; and 3) a viral model for peer sharing audio health content using mobile phones and traditional social networks. These are services from just one country: Kenya. Worldwide, mobile and interactive innovations represent fundamental shifts in how we think about health and healthcare. These innovations are leapfrogging traditional models. What can we adapt to the US health system (and market) in the next 2-3 years?
