A new national patient survey has found small improvements were achieved in three stages of care - care on the ward; examinations, diagnosis and treatment, and discharge or transfer.
Long waiting times in the emergency department were highlighted as a problem in the National Patient Experience Survey 2018.
Just 31% of patients said that they were admitted to a ward within the Health Service Executive's target waiting time of six hours.
The survey found that 3% said that they waited 48 hours or more before being admitted to a ward.
There was no change in the area of admissions or patients' overall rating of care when compared with the 2017 data.
Over 13,400 of the 26,752 eligible patients completed the survey, resulting in a response rate of 50%.
The survey took place in May and was the second of its kind.
