NHS Online, which will see its first patients next year, is expected to deliver up to 8.5 million virtual appointments and assessments in its first three years – four times more than an average NHS trust.

The NHS England research reveals 60% of consultants would be interested in working for NHS Online alongside their current NHS roles – many more than will be needed to run the service.

The survey of nearly 300 consultants and specialist doctors also found that 48% would be willing to offer at least four hours a week of their time, with the opportunity to care for patients innovatively, work flexibly and improve patient experience among their top reasons for wanting to sign up.

Professor Stella Vig, national clinical director for elective care at NHS England and consultant surgeon, said: ‘It's fantastic to see that consultants and specialist doctors are hugely supportive of the NHS's new online hospital, with nearly two-thirds willing to offer their time for this revolutionary service alongside their current roles.

'NHS Online will transform the way we deliver planned care, offering patients the choice to have an online appointment with a specialist anywhere in England.'

Prof Vig added: 'We've also expanded the list of conditions which NHS Online will treat, so that even more patients will be able to benefit when the service launches next year.'

Health minister, Zubir Ahmed, said: 'Patients shouldn't have to wait months or travel miles to get the care they need. By turbocharging the NHS with the latest technology, NHS Online will let people see specialist doctors faster - from the comfort of their own home.'

NHS Online is being designed with patients, specialist doctors and other experts to ensure the service meets the needs of patients, uses the latest technology follows best practice and provides the highest standards of care.

Findings from the survey of consultants and further engagement with NHS staff will be used to develop plans for the service.
