Cheap, accessible and easy to use, mobile phones are everywhere. With the advent of the smartphone has come a new kind of healthcare - M:Health - in which mobiles are playing a key role in monitoring and improving the health of communities around the globe. Linking remote communities in developing countries with professional healthcare, mobile phones are helping break down long-standing barriers to accessing treatment. Use of M:Health is also growing in developed countries, helping patients to monitor and manage their own health, thereby reducing pressure on health services. According to the World Health Organisation the burden of deaths from non-communicable diseases will climb from 28 per cent in 2008 to 46 per cent by 2030. The George Institute for Global Health is investing in research into innovative new strategies for tackling the burden of chronic disease.
