Data for Northern Ireland is maintained by the Health & Social Care Board, Information Standards Service. Current data for purchasers and providers, GPs and GP practices are provided. Health and Social Care in Northern Ireland is administered over 5 geographic areas – each of these areas is served by a Health and Social Care Trust and a Local Commissioning Group. These five areas are overseen by one Health and Social Care Board which has the overall responsibility for commissioning, resource management, performance management and improvement across the whole of Northern Ireland. This structure was introduced following the Review of Public Administration (RPA) in Northern Ireland and formally came into effect on 1 April 2009. The five Local Commissioning Groups (LCGs) are committees of the Health and Social Care Board and are responsible for the commissioning of health and social care of their local population. Each LCG is co-terminus with their respective Health and Social Care Trust area. There are five trusts in Northern Ireland providing health and social care services to the Northern Ireland public. Services are provided locally and on a regional basis Users should note that there are currently two different code structures used for Northern Ireland Commissioning Groups due to historic format restrictions applied to the publication files. A 5-character code is used for the Health Board's records in the NIorg.csv file and references to them in nlhscgpr.csv, whilst these are truncated to a 3-character code for use in the postcode directory products supplied by ONS. As these three character codes are not published in their own dataset we have provided a simple lookup file in order to tie the different code structures together. A file (XLS, 22.5kB) has also been provided containing the same lookup, including addresses.
