General description
This table provides the current diagnostic and therapy services waiting times data.

Data collection and calculation
Please find this information in the related statistical release, as per the given weblink.

From 1st April 2019 health service provision for residents of Bridgend local authority moved from Abertawe Bro Morgannwg to Cwm Taf. For more information see the joint statement from Cwm Taf and Abertawe Bro Morgannwg University Health Boards (see weblinks). The health board names have 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. A link to the statement from the minister for health and social service can be found in the weblinks section.

Sites that were previously included under Community in Betsi Cadwaladr have been included individually in the data from October 2019 onwards. These sites are Abergele Hospital, Bryn Beryl Hospital, Cefni Hospital, Dolgellau & Barmouth District, Eryri Hospital, NW Cancer Treament Centre, Ruthin Community Hospital, Tywyn & District War Memorial, Ysbyty Alltwen and Ysbyty Penrhos Stanley.

Revisions information
In January 2020, Diagnostics and Therapies data for Betsi Cadwaladr was published for six additional sites with a back series as far back as April 2018. Previously the data for these sites had been published under the broader ‘community’ site category.

Statistical quality
Please find this information in the related statistical release, as per the given weblink.
Due to a data issue, figures for nuclear medicine for Aneurin Bevan were under reported between February 2015 and July 2015 inclusive. During these months data for Myocardial Perfusion Scans were not reported under nuclear medicine, whereas outside of these months this test was included under nuclear medicine. Therefore, the decrease in patients seen in February 2015 and the increase seen in August 2015 were due to the way the data were reported, rather than changes in actual numbers of patients. This has caused a difference of approximately 350-400 patients each month, and approximately 150 to 190 of these each month were waiting 8 weeks or longer for their scan. Therefore the exclusion of these patients slightly improves the Welsh performance against the standard.
Diagnostic Endoscopy, Dietetics, Occupational Therapy, Physiological Measurement, Physiotherapy and Speech Language for Withybush General Hospital (Hywel Dda Health Board) have been estimated for September 2010 – May 2011 using data from August 2010 as they were unable to submit data due to migration from PAS to Myrddin.
Physiotherapy data for October 2012 for Cardiff and Vale University Health Board are estimated using their data for September 2012, as they were unable to provide full data on physiotherapy for October 2012.
Physiotherapy data for February 2013 for Cardiff and Vale University LHB are estimated using their data for January 2013. This is due to Cardiff and Vale University being unable to provide full data on physiotherapy for February 2013, because staff sickness resulted in patients not being entered into the system in time for the submission.
Radiology & imaging data for June 2013 for Cardiff and Vale University LHB are estimated using their data for May 2013. This is due to Cardiff and Vale University experiencing technical difficulties with the base data.
Neurophysiology data for April 2014 for Betsi Cadwaladr University LHB are estimated using their data for March 2014, this is due to the implementation of the service to a new hospital site which resulted in the April 2014 data being unreliable and hence not submitted by the LHB.
Data for April 2017 for Cwm Taf University Health Board are estimated using their data for March 2017, as they were unable to provide any data for April 2017.

From the April 2018 data (from the June 2018 release of this publication onwards), additional diagnostic tests for Cardiology have been included in the Diagnostic and Therapy waiting times data. These new records have been included in the waiting time totals and as a result there has been an increase in the number of people waiting for a diagnostic test.
