Electronic Staff Record

Electronic Staff Record or ESR is an Oracle-based human resources and payroll database system currently being rolled out throughout the NHS in the UK. ESR is provided by the healthcare systems corporation McKesson.

The ongoing implementation of ESR is one of the largest IT implementations in the world and will replace 29 payroll systems and approximately 38 human resources systems used throughout the NHS. On completion a total of 1.2 million NHS staff members will be paid by ESR. The NHS is variously the third or fifth largest employer in the world, after the Chinese army, Indian Railways and (as argued by Jon Hibbs, the NHS's head of news, in a press release from March 22, 2005) Wal-Mart and the United States Department of Defense.

Delivery
Implementation of ESR been completed in nine of the twelve planned waves to date. New waves 'go live' approximately every two months and each consists of around 50 trusts. Wave 10 is due in October 2007.
