Logan Hospital stands by its handling of an incident in which a mental health patient was tackled to the ground, and that it was appropriate to involve a security guard to restrain her.

Toni Burcher had been admitted to the hospital on May 5 for treatment relating to her mental health issues, but she and her husband Robert Cowling were reportedly unhappy with the behaviour of staff.

CCTV of the confrontation shows Ms Burcher being tackled to the ground, which left her concussed and with a gash to her scalp.

“What scared me was the impact,” Ms Burcher told 9NEWS.

Her husband, Robert, was also wrestled and held face down by another guard during the incident.

“You can actually see the guy rushing at her, grabbing her and throwing her on the ground,” he said.

“The way we were treated that night was disgusting.”

The security guards reportedly kept Ms Burcher restrained on the ground for six minutes despite medical staff attempting to treat her head wound.

Acting Chief Executive of Metro South Health Robert Mackway-Jones said they regret the incident, however there was a broader context.

"With the way that the patient presented (to the hospital) it was entirely appropriate that security were involved to restrain her," Mr Mackway-Jones told reporters today.

"You really need to understand the full context. The footage that has raised all these questions is only part of the overall care for the patient, so really if you understand the wider context of what has happened, it paints a very different picture."

Mr Mackway-Jones said Queensland Police had conducted an investigation into the incident and the Health service had also conducted an internal review, with both finding no case to answer.

The couple are understood to have made a complaint to the health ombudsman, and Mr Mackway-Jones said they would cooperate fully with any further investigations.

Premier Annastacia Palaszczuk said security officers in hospitals should act respectfully, but she understood there was more to the matter.
