Data for England is shown by NHS trust, where the trust includes at least one hospital with a Type 1 A&E department. Type 1 means a consultant-led 24 hour A&E service with full resuscitation facilities.
When you enter a postcode for a location in England you will be shown a list of NHS trusts in your area. They will not necessarily be in order of your closest hospital as some trusts have more than one hospital. Data for Wales and Scotland are shown by NHS board and by Health and Social Care trust in Northern Ireland.
Comparative data is shown for a previous year where available. However, where trusts have merged there is no like-for-like comparison to show. Earlier data is not available for all measures, so comparisons between years are not always possible.
Each nation has different target times and ways of categorising data for the measures shown, therefore comparisons between them are not possible.
