Fujitsu Services PR manager Graham Goulden said the move was triggered by new work for the NHS, HM Revenue and Customs, and Lloyds TSB, which has altered Fujitsu's comms issues.
Firefly, whose tenure on the account predates the rebranding of Fujitsu Services from ICL, is defending the £250,000 brief against Lewis Communications and Harvard.
The company provides the software behind the NHS's National Programme for IT, to put patient records online, for the South. Other providers have contracts to enable the project elsewhere in the country.
Goulden said the account focused on three areas: B2B comms via trade and IT publications; targeting potential clients, particularly those in financial services, utility and public sectors; and promoting Fujitsu Services as a source of 'authoritative industry comment'.
The £6.2bn IT system has been criticised because of concerns that local NHS trusts could be forced to foot the bill if its cost increases, although the Government has said that the cost would be sustainable.
Last month it won a £170m contract to handle Lloyds TSB's core IT services and in March signed a seven-year outsourcing contract with WH Smith.
The review follows Firefly's loss last year of its PR and B2B account with Fujitsu Siemens Computers.
