Barts and the London NHS Trust has become the third NHS trust in London to go live with a Cerner Millennium Care Record System (CRS) supplied by BT under the £12.4bn NHS IT Programme.

The trust switched on the new system over the weekend, going live in A&E, inpatients and outpatients, with functionality including case note tracking.

Barts and The London is one of Britain’s top teaching hospital trusts, comprising St Bartholomew’s in the City, The Royal London in Whitechapel and The London Chest in Bethnal Green. The implementation is one of the most complex and challenging so far undertaken by the NHS IT programme.

BT has previously installed the Cerner system at Queen Mary’s Sidcup (QMS) and Barnet and Chase Farm, in its role as Local Service Provider for London.

A trust spokesperson confirmed the go-live, but declined to give further details: “We can confirm that Barts and The London has gone live with the new CRS system (Cerner Millennium Release 0) this week,” she said.

A spokesperson for BT confirmed to E-Health Insider that the system had gone live across all sites.

The BT spokesperson said future implementations of Millennium in the capital would be of the London cluster version of Millennium Release 1 software. The Royal Free Hampstead NHS Trust is expected to be the first trust to receive this towards the end of May.

Barts and The London was first due to go-live at the end of last year, but was delayed due to ‘outstanding issues’. Implementation was further delayed last month before the trust eventually went live on 5 April.
