Cause of death

The effects of restraint and drugs

AI-generated summary

Warren Osborne, a 45-year-old man affected by amphetamines and experiencing drug-induced psychosis, died during physical restraint at Caboolture Hospital. After being triaged in the Emergency Department, he accessed restricted hospital areas through faulty security doors and entered Ward 2A. Following failed persuasion, nursing and security staff restrained him in a prone position for over 10 minutes. The restraint combined with amphetamine-induced cardiac effects caused sudden arrythmogenic cardiac arrest. Contributing factors included inadequate training of security staff in positional asphyxia risks, failure to move him to recovery position after resistance ceased, and absence of handcuffs that might have enabled quicker positioning changes. The coroner identified that training should emphasize physiological risks of prone restraint and that staff demonstrating incompetence in restrictive practices should not be deployed to such roles.

  • Drug intoxication producing agitation and acidotic state
  • Staff unaware of physiological risks of prone restraint
  • Catecholamine and lactate release during restraint

Coroner's recommendations

  1. Establish clear lines of communication and authority between Metro North Protective Services and line managers to ensure mandatory occupational violence prevention training is undertaken within specified timeframes, particularly for emergency response team members
  2. Hospital and health service officers who are members of emergency response teams and fail to demonstrate competence in restrictive practices training should not be deployed to perform such practices, consistent with Queensland Police Service policy
  3. Metro North Hospital and Health Service should adopt aspects of Queensland Police Service practical training on physiological impacts of positional asphyxia to reinforce risks of prone restraint to those engaged in this practice
