mixed drug toxicity (methadone, valproate, zuclopenthixol)
AI-generated summary
Michael David Rex, a 41-year-old man with chronic treatment-resistant paranoid schizophrenia, died from mixed drug toxicity (methadone, valproate, zuclopenthixol) while detained in Ward 5H of the Margaret Tobin Centre psychiatric facility. He was placed in an open ward after 9 days in a closed secure ward; methadone was not a prescribed medication. The source of methadone remains unknown but likely came from an unknown visitor or through gaps in the perimeter fence. Critical clinical lessons: delayed toxicology results (not known until January 2009) hampered investigation; investigations should have considered drug ingestion as a possibility immediately; hourly sleep checks failed to detect deterioration in a deeply sedated patient; security gaps around psychiatric facilities pose contamination risks; visitor recording systems and perimeter security require review to prevent contraband access while maintaining therapeutic environment.

Coroner's recommendations
Review the physical nature of fencing to the rear garden area of Ward 5H to prevent passage of illicit drugs
Implement policy to govern visitor access to Ward 5H including visitor guidelines, visitor identification requirements for detained patients, and maintenance of visitor record book with documentation of staff observations of patient-visitor interactions
Review routine guidelines and reassess manner of checking patients during night and when asleep during day; reassess timeliness of medication administration and provide refresher training
Introduce guidelines for minimal course of action by ward staff upon finding of deceased detained persons, including scene securing, witness identification, and mandatory provision of CCTV footage to investigators as soon as practicable
Ensure all CCTV footage is retained and not overwritten until permission obtained from State Coroner or police
Ensure investigating police take proactive role in identifying possible investigative issues rather than relying on witnesses; police should consider toxicological component in unexplained deaths in hospital settings even before toxicology results available
