Profile Contents


John Powell is an academic public health physician and health services researcher with a particular interest in ehealth and connected health: investigating how information and communication technology can be used to improve health and health services. He is a Senior Clinical Researcher at the University of Oxford and also works for NICE and NHS Choices. His ehealth projects are in two main areas. Firstly, evaluating the effectiveness of ehealth tools – for example: a randomised trial of an internet-based intervention to promote mental wellbeing in the general population; a randomised trial of an internet intervention for cardiac rehabilitation; the development of a serious game intervention for childhood obesity and the development and piloting of a virtual reality tool for the treatment of social phobia. Secondly, investigating how a connected health world is changing how patients and the public interact with services and manage their own health – for example: a study examining the sharing of online patient experiences; and a study examining how young people are engaging with health care in new ways.
