A man has told the Covid-19 Inquiry that he believes his mother was denied the chance of survival in April 2020.
Glen Grundle from Coleraine was at times tearful as he spoke about his mum Milda's experience in hospital, describing "issues at all levels", and calling for accountability.
He was among a number of members of the Northern Ireland Covid-19 Bereaved Families for Justice group to give evidence to the latest module of the UK Covid-19 Inquiry on Tuesday.
Mr Grundle gave evidence on the impact of Covid-19 restrictions on funerals and wakes in Northern Ireland, describing the coming together of families and friends to share memories as "very much part of the culture here".
He also described examples of the impact of "pandemic grief", such as him not having given anyone a "proper hug" since the last time he saw his mother.
Appearing remotely before the inquiry in London, Mr Grundle said his mother, Milda Grundle, who had MS, was taken to hospital in early April 2020 and said she was "immediately put under pressure" to agree to DNACPR, a Do-Not-Resuscitate order.
Mr Grundle told the inquiry that a consultant said she had "no quality of life" because she used a hoist and had carers.
"I was absolutely shocked, I argued with him on the telephone, I told him that there would be repercussions ... I couldn't believe someone was playing God, which can never be allowed to happen," he said.
"Quality of life is something only that person knows."
He said he started emailing politicians and doing media interviews to highlight his concerns, and said that the consultant was later removed from his mother's case.
However, he said there were continued efforts to get his mother to agree to a DNACPR, adding she accepted to a certain extent when they told her she wouldn't get a ventilator in the Intensive Care Unit.
At that time, he said there were warnings in the media about the health service being short of resources, adding hospitals were "terrified at the anticipated tsunami of patients" that they had seen in other countries.
"It's my personal belief that my mum was denied a chance at survival," he said.
"The DNACPR has room for three signatures and only one consultant signed it, there were supposed to be three different people involved in the assessment, and I don't consider it valid ... of course, I didn't have access to the hospital, so I didn't know what was going on."
Mr Grundle said he wants answers about his mother's care and how she got Covid-19, adding he has been campaigning for an inquest into her death.
"I really haven't started to grieve ... if we can't even get information, to accept what has happened, to understand," he said.
"You see this with Hillsborough as well; the families' pain is prolonged; that's why the work on the duty of candour is so important.
"We need to have access to this information. I'm never going to have closure or peace about what happened to my mum, but I at least need that information to know what happened, and then to be able to go on and get some accountability.
"Truth, accountability and justice for my mum, and that's what we want."
Marie McArdle and Julie McMurray are also giving evidence to the inquiry on Tuesday.
