At the end of February, the Mid-Western Regional Orthopaedic Hospital in Croom had 4,148 patients waiting four years or more.
There were 105,632 patients waiting over a year for a first consultant outpatient appointment across Ireland.
This represents a small improvement on the figures up to the end of January.
The hospitals with the longest overall outpatient waiting lists were:
– University College Hospital Galway 41,035 patients
– Waterford Regional 28,625
– Tallaght Hospital 26,119
– Limerick Regional 23,098
– Cork University Hospital 22,944
– Beaumont Hospital 22,206
The HSE West said that it expects to make significant improvements in the outpatient waiting list for services at the Regional Orthopaedic Hospital in Limerick by the end of this month.
It said that all hospitals are validating outpatient waiting lists and historically lists have contained inaccuracies for many reasons.
It said the waiting list at the hospital as of 1 May for an outpatient appointment is 7,477.
The HSE West said that it aims to have the list validated by the end of May and have no patient waiting longer than a year for an orthopaedic appointment by the end of November.
