The figures show, however, that two of the three leading Dublin maternity hospitals — the Coombe and Holles Street — are not even in the top 10.
The maternity statistics were based on 9,200 fully completed 23-part online patient surveys carried out over the past 12 months.
They put Portiuncula in first place nationally, followed by South-Tipperary General in second and Dublin’s Rotunda Hospital in third.
Mayo General Hospital was in fourth place in the patients’ ratings chart, with the Midland Regional in Mullingar fifth.
Dublin’s Coombe Hospital was in 13th place, with the National Maternity, Holles Street in 15th place in the league table.
Last in the table were the maternity services provided at Donegal’s Letterkenny General Hospital.
As part of the Rate my Hospital survey, patients and their relatives are asked to rate hospitals on a scale of one to five based on recent hospital experience under a number of headings relating to quality of care and facilities. They are also asked to name the relevant hospital specialty.
Meanwhile, in Rate my Hospital’s latest league table for A&E services, South Tipperary General Hospital, Our Lady’s Children’s Hospital, Crumlin and St John’s in Limerick are in joint first place. Roscommon County Hospital, which was formerly top of the table, has fallen to seventh place, while the Mater in Dublin remains rated by patients as Ireland’s worst A&E.
