The DoH target is for 95% of patients to be treated, discharged or admitted within four hours and no patient to wait longer than 12 hours.
Dr Corrigan, who is an emergency medicine consultant, has called on the department to spend its money more effectively.
A Freedom of Information request from BBC News NI revealed that every health trust in Northern Ireland experienced patient waits of about week or more.
The Northern Health Trust said a wait of more than 10 days for a patient in Antrim Area Hospital was because they needed to be isolated in a side room for other people’s safety.
“If there’s space, it’s taken up by somebody,” said Dr Corrigan.
She added that patients who might be vomiting or suffering from diarrhoea were queuing for the one toilet available in a unit.
“It’s a soul-destroying work environment. You can’t give the care you want to give,” she said.
“You certainly aren’t giving the care you’re trained to give. It’s not the care you’d want your family to receive.”
There are currently hundreds of people stuck in hospitals across Northern Ireland who are medically fit to be discharged but do not have a care package or an appropriate facility to go to.
The BMA said this increases pressure in EDs because people are not moving through the hospital system.
