British Telecom (BT) has secured a five-year deal worth up to £20m with Belfast Health and Social Care Trust.
BT has been chosen by the trust to provide 17,000 users with new technology that will support the drive towards care in the community across Northern Ireland.
The recently published Compton Review of Health and Social Care in Northern Ireland, 'Transforming Your Care, indicated the need to focus on care in the community.
Head of BT's NI public sector and major accounts, Peter Russell, said: "BT has been working with the National Health Service in the UK for many years, building a long-term relationship based on understanding the challenges and objectives around healthcare.
"We are delighted to have the opportunity to work in partnership with the Belfast Trust, bringing the very latest communications technologies to bear that will over time hopefully transform the way healthcare is provided in Northern Ireland."
This strategy will require the effective use of a communications framework and will transform the way healthcare workers communicate and share information.
Paul Duffy, Belfast Health and Social Care Trust, said, "We chose BT to develop our next generation of voice and data communications services that will greatly enhance healthcare services to our 340,000 patients and clients.
"We look forward to working with BT on delivering real benefits to staff and patients, and facilitating new ways of communication and teamwork."
