An independent review of 9 hospitals across the country, including the Midland Regional in Tullamore, and Galway University Hospital, found 'unsafe' and 'unacceptable' treatment at all of them.
It's also recommended an end to the practice of placing trolleys on wards once the health system becomes stabilised.
The review of unplanned care looked at 9 hospitals which were under huge pressure during the 2018/2019 winter season - however it was never published by the HSE who felt it was no longer relevant in light of the Covid pandemic.
It's now in the public domain following a Freedom of Information request by the Irish Patients Association.
The Irish Examiner says the report states that 50% or more of patients spent at least one night on a trolley before getting a bed or being discharged, while in at least 1 hospital patients spent up to 10 nights on trolleys.
The review recommended an end to the practice of placing trolleys on wards once the health system becomes stabilised.
