Originally designed simply as an electronic booking system, Choose and Book was developed to enable patient hospital choice. It was introduced into the NHS from 2005 onwards. It was procured as part of the National Programme for IT (NPfIT) in 2003. The contract was awarded to Schlumberger Limited's Sema division just before its acquisition by Atos Origin. The software is based on Cerner Corporation's Millennium e-Booking software.
