The agency's health division has been asked to provide strategic advice, policy and public affairs support for Tunstall, which specialises in remote services that monitor patients in their homes.
Under the changes proposed by the Government in the Health and Social Care Bill, £80bn of the NHS budget is to shift from Primary Care Trusts to new bodies run by GPs, potentially placing a stronger emphasis on self-care.
Last November, Health Secretary Andrew Lansley said: 'Technologies such as telecare and telehealth are already increasingly used to help people stay safe in their own homes.'
Tunstall maintains that telehealthcare can help people remain independent by providing support for patients to better self-care, thus reducing GP visits and hospitalisation.
Ali Rogan, comms director at Tunstall, also claimed its services could help free up NHS resources.
'This is a big year for the NHS and social care services,' he said. 'We are confident that telehealthcare will make a significant difference, improving outcomes, enabling patients to live more independent lives and freeing up NHS and local authority resources.'
MHP Health MD Mike Birtwistle will lead the 15-month retained account.
'The new world will look very different to NHS commissioners, patients and suppliers alike,' said Birtwistle. 'Tunstall is a world-class firm providing world-class services to patients.'
