Finding into death of Jeffrey John Hartwig

Contributing factors

• Combined toxic effects of multiple psychoactive medications (methadone, quetiapine, fluphenazine, benzodiazepines, sodium valproate)
• Paranoid schizophrenia with altered mental state
• Possible central nervous system depression leading to respiratory depression
• Possible aspiration related to sedation and vomiting
• Inadequate monitoring of sedation level despite clinical indicators
• Cessation of formal vital observations after 10 December despite fever and respiratory symptoms

Coroner's recommendations

1. Continued implementation and refinement of Monash Health's procedures for management of illicit and non-illicit substances in acute mental health inpatient units, in compliance with Victorian Department of Health Chief Psychiatrist guidelines
2. Ongoing development and delivery of training for nursing staff on recognition of abnormal breathing patterns and respiratory distress
3. Implementation of formal sedation scoring protocols using standardized sedation scales (aiming for sedation score <2) when patients are on multiple psychoactive medications
4. Establishment of clear protocols for continuation of formal vital observations and sedation monitoring when clinical indicators of infection, fever, or respiratory concerns are identified
5. Continuation of enhanced nursing training and frameworks emphasizing observation of patient breathing without hindrance, particularly when patients are on multiple CNS depressants
