Security was called after Theodorus van der Veen, 81, took hold of a fire hose and activated it in a ward of the Prince Charles Hospital in April, the Brisbane Magistrates Court heard.
Shane Kilgariff allegedly tackled Mr van der Veen, with both men falling to the ground.
Police will allege it was the injuries inflicted during the incident that subsequently saw Mr van der Veen die two weeks later.
Kilgariff, 50, was granted bail on the condition that he report to police once a week and not travel internationally.
The court was told that Kilgariff still works at the hospital but since the incident has been employed in an administration role.
Queensland Health has launched an investigation into the incident.
“As with any serious matter, we have launched an internal investigation into this incident,” Queensland Health said in a statement.
“As this matter is now before the courts, we are unable to comment further.”
