The consultant at the centre of an investigation into spinal surgery complications at Temple Street Children's Hospital continued working despite safety concerns.
The HSE has appointed a UK expert to carry out an external review of the consultant's clinical care.
It's in response to 19 children suffering serious complications following surgery over the last year.
Paul Cullen, Health Editor with the Irish Times, says questions have been raised about how long the issue went unaddressed:
"Staff were expressing concern from September 2022, and progressively Children's Health Ireland acted to reduce the person's work."
Paul says the person ceased doing spinal surgeries in May, and all surgeries in July of this year.
Stephen Morrison's son Harvey has been waiting for surgery for a number of years but it's been postponed and he says action needs to be taken:
Stephen said he and his partner were "shocked" and "scared."
"What these kids have already gone through in their lives is beyond what most of us can imagine," he said.
Stephen added, "they've been left aside too long."
Helpline
Children's Health Ireland has announced a new helpline for those affected by the spinal surgery scandal.
In a statement this afternoon, the Temple Street operators said they have made staff available to answer any queries relating to spinal surgeries at the hospital.
Anyone affected can call 01 409 6117 between 9am and 5pm Monday to Friday.
