The last redevelopment of the 136-year-old hospital only catered for growth up to 2006 and it was now performing over capacity,the report said.
The hospital was experiencing"severe bed blockages",whereby patients banked up in the emergency department because there were no spare beds on the wards.
This was due to the pediatric in-patient unit having no surge capacity,the discharge lounge being too small and the constraints of the emergency department itself,which was housed in a heritage building bounded by imaging services and had no room to expand.
An estimated 58 new treatment spaces would be required in the emergency department on top of 2011 levels by 2027.
