The fallout from Fujitsu severing ties with the NHS National Programme for IT (NpfIT) continues, with the rumoured potential loss of some seven hundred jobs at Fujitsu. 1,000 Fujitsu employees work within the NHS programme.

Also at stake are £340 million in revenues. The company has until the end of this month to pay back the NHS £67 million of the £143 million it received in advance payments.

Fujitsu walked away from talks earlier this month, prompting the NHS to terminate the 10-year, £846 million deal as the South's technology service provider. Contract renegotiation terms had proved unacceptable to the Japanese company, which pressed the NHS for a return to the original deal.

Trade union Unite, which has been a highly vocal critic of several troubled outsourcing deals this year, has urged the Government to take action to prevent a haemorrhage of skilled workers from the programme.

“Government must act to ensure that the knowledge and skills gained in working for Fujitsu are retained, whoever the provider or providers are in the future, and ensure that the skilled staff can help the project continue to a successful conclusion in the interests of patients, the NHS and the health of the nation,” said Unite national officer for IT workers, Peter Skyte.

Last week the Public Accounts Committee (PAC) sat at Westminster to hear of central Whitehall mismanagement and local NHS tensions – a story that calls into question the viability of a central IT scheme imposed on local Trusts that have differing needs, skills and funding challenges.

Fujitsu executives told MPs that constant local modifications coupled with the withholding of funds forced the outsourcer's hand. The changing terms of the contract would have been unaffordable, claimed Peter Hutchinson, UK public services group director at Fujitsu Services, who said there had been over 600 such alterations.

"We withdrew from the re-set negotiations. We were still perfectly willing and able to deliver to the original contract," he said. “There was a limit beyond which we could not go,” he added, referring to the company's employees, investors and pensioners.

In turn, the termination of the deal has left the NHS with a "gaping hole", said the PAC chairman Edward Leigh. NHS COO Gordon Hextall said that BT was in the running to take over the eight former Fujitsu sites in the South of England.

• All hospitals in England and Wales were supposed to have had patient record systems installed by the end of 2006, but only 34 out of 169 have received their systems so far and, of these, 21 are reportedly outdated.
