Overview

• Summary of dataset and variables:

  Data on attendances and waiting times at emergency departments in Wales, reported by Local Health Boards.

  Data are provided for major emergency departments and other emergency departments and minor injury units. Data for other emergency departments / minor injury units are only available from April 2012.

• Data collection or calculation:

  Data are drawn from Local Health Board administrative systems relating to the management of patients who have been referred for hospital treatment. Data are reported monthly by Local Health Boards via Digital Health and Care Wales (DHCW) and are available from October 2009.

  In April 2019 health service provision for residents of Bridgend local authority moved from Abertawe Bro Morgannwg to Cwm Taf. The health board names changed, with Cwm Taf University Health Board becoming Cwm Taf Morgannwg University Health Board, and Abertawe Bro Morgannwg University Health Board becoming Swansea Bay University Health Board.

• Statistical quality:

  Data definitions and standards are mandated by the Welsh Information Standards Board (WISB).

  During the COVID-19 pandemic, several Minor Injury Units temporarily closed temporarily. These were Barry hospital (closed in March 2020; reopened in August 2020); Bryn Beryl (closed in May 2020; reopened in August 2020); Dolgellau and Barmouth District Hospital (closed in April 2020; remains closed); Tywyn & District War Memorial Hospital (closed in June 2020; remains closed); and Llandovery (closed in April 2020; remains closed).

  Emergency department data for Betsi Cadwaladr University health board for December 2025 to March 2026 have been revised. The data originally published indicated a significant fall in 4-hour performance compared with previous figures, however the revised figures show performance was relatively stable.

• Rounding applied:
