Rebecca Jackson, 20, a mental health patient at Leeds General Infirmary, stabbed a student nurse three times in the back after walking out of the hospital in April last year.
Tanya Mitcham nearly bled to death as the stab wounds severed an artery, and had to have major surgery to save her life.
In the court hearing today Jackson has been deemed not well enough to face the criminal charges against her, despite the jury finding that she committed the act.
Jackson walked out of the LGI after telling a nurse that she wanted to kill her mother, she then stole a 12-inch knife from a shop in the city centre before attacking the student nurse at the city bus station.
It is expected that Jackson will be made the subject of a hospital order after a psychiatrist gives evidence at the hearing today.
