Residents in the Cwm Taf Health Board area are facing a wait of up to eighteen months for hearing tests.
The disgraceful figures were revealed by RCT Welsh Liberal Democrats following a freedom of information request . RCT Campaign Manager Karen Roberts says it is unacceptable
"The request was submitted following feedback from a number of residents who had attended the local audiology clinic and been told they needed a hearing test but that the wait was more than 70 weeks.
"The actual statement from Cwm Taf puts the wait at 73 weeks, so people being put on the list now face not being given an appointment until November 2015.
"It is yet another example of how Wales is lagging behind the rest of the UK under the Welsh Labour Government. Diagnostic waiting times are unacceptably high across a whole range of specialities. In the case of people who are suffering from an impairment of hearing then it may not be life threatening, but it does affect their quality of life.
"The people of Rhondda Cynon Taff are being sold short by their elected representatives. Why is this being allowed to continue?
"We are constantly at or near the bottom of the league table when it comes to ambulance response times, with figures regularly showing less than 50% of category A emergency calls being responded to within 8 minutes.
"On top of that people in Rhondda and Taff Ely have been sold out by the Health Board who rolled over and agreed to the South Wales Programme decision to remove services from the Royal Glamorgan. They have been let down constantly by the Labour Government."
For the end of April 2014, figures show:
• 27% of Welsh patients wait over 18 weeks to start treatment in Wales, while just 6.2% are waiting the same period in England
• 12% of Welsh patients wait longer than 4 hours in A&E, while in England only 4.2% wait longer than 4 hours
• 30% of Welsh patients wait over 8 weeks for diagnostic tests, whilst in England just 2% wait over 6 weeks
