"Stephen McMahon, co-founder of the patient rights and safety advocacy group the Irish Patients Association (IPA), said: “We see that some steps are being taken to improve patient flow through EDs but this revelation regarding turnaround times is yet another example of deteriorating conditions.

“The increase in emergency ambulances turnaround times nationally signals a further exposure to risk for patients in the community as ambulance capacity is reduced and its service becomes more challenged.” Mr McMahon stated that the latest figures mean the National Ambulance Service (NAS) would have to double its fleet to achieve an average 30 minute turnaround time.

“We appreciate the great work that our emergency responders do and those who work in overcrowded EDs - this deterioration is not their fault,” he added. “It has happened over a long time due in part to poor governance and accountability at all levels.”
