Over 115,000 people left an emergency department without finishing their treatment last year.
It represents over one in 13 people who attended an ED, according to freedom of information figures.
Almost 1.5 million patients went to emergency departments last year.
115,165 of them left without completing their treatment.
That's 7.8 per cent.
The highest was in Tallaght University Hospital, at 20 per cent, followed by St James's Hospital, also in Dublin, at 12.9 per cent.
Our Lady of Lourdes Hospital in Drogheda was next, at 12.1 per cent.
The HSE says emergency departments are for people with serious injuries or illnesses, but many others go there when they do not need to.
It says patients are treated by priority and, because of that, some patients with less serious needs may choose to get healthcare elsewhere.
