West Hertfordshire Hospitals NHS Trust has put out an ICT contract for tender worth up to £50 million over five years.
The ICT infrastructure improvement programme contract will support the work of almost 4,000 staff across three main sites and one satellite site.
Services required include the provision of a service desk; service management including disaster recovery, business continuity and security; data management including storage, back-up and archiving; and information management covering desktops, laptops and other devices.
The contract also covers unified communications across LANs, WANs and mobile networks; and videoconferencing, fixed and mobile telephony, printing services, and application hosting.
The trust said: "Bidders will be aware of the continuing changes that are occurring both in technology, and within the NHS at large.
Bidders must be able to flex their service arrangements to take into account these changes in technology and organisational structure that will inevitably occur during the five-year life of the contract."
The trust said it may want to extend the contract to cover clinical or information systems, business applications, portals and digital service user engagement, such as tele-health.
"The services may be extended under this contract either during the procurement process itself, or during the term of the contract under change control procedures," the trust said.
The estimated contract value is between £30 million and £50 million. There is also the possibility that the five-year deal could be extended by a further two years at the trust's discretion.
Bids of interest have to be in by May 22, with full invitations to tender sent to suppliers on June 6.
University Hospitals of Leicester NHS Trust recently signed a major IT management services outsourcing deal with IBM.
