The Whole System Demonstrator programme, which spanned three and a half years and recruited more than 6000 patients and 230 general practices at a cost of £30m (€37m; $47m), is one of the most complex and ambitious trials ever conducted by the NHS and the biggest assessment of telehealth and telecare in the world.

Launched in May 2008, it was designed to answer one deceptively simple question for a health service hungry for innovative ways to manage the escalating costs of caring for an increasingly elderly population: does the use of technology as a remote intervention make a difference?
