Ms S complained that despite raising concerns about her daughter in June 2022, Betsi Cadwaladr University Health Board failed to provide her with a complaint response.
The Ombudsman concluded that the Health Board failed to communicate an update to Ms S and further failed to comply with its statutory complaints procedure.
As an alternative to an investigation, the Ombudsman sought and gained the Health Boards agreement to apologise for the delays and provide a formal response to Ms S within 30 working days.
