Health Inspectorate Wales (HIW) has raised concerns at the Cynnydd and Dinas wards in the Ablett Unit at Glan Clwyd Hospital, Bodelwyddan, Denbighshire. The hospital mental health unit has been told to make improvements after an inspection found some issues put patient safety at risk. The former Tawel Fan ward, which was part of the unit, shut in 2013 after reports about patients' care. HIW said it was also concerned to find that some issues it identified in its previous inspection in 2014 were still apparent, despite Betsi Cadwaladr University Health Board developing a clear action plan to resolve them.
