AI-generated summary
Kumanjayi, a 34-year-old Aboriginal woman with schizophrenia and chronic pulmonary disease, died in the mental health inpatient unit from combined drug toxicity and respiratory failure. She received 198% of the recommended maximum antipsychotic dose without medicine reconciliation. Clinical failures cascaded: staff mischaracterized her as 'aggressive' (she was cooperative), justifying inappropriate intramuscular sedation; mandatory physical observations and pulse oximetry were not performed despite respiratory risks; medication orders were given verbally without proper documentation; handovers between ED and inpatient unit were rushed and incomplete; and deterioration was not escalated. The coroner found her death entirely preventable: proper medication reconciliation, mandatory monitoring per procedure, accurate documentation, timely escalation to senior clinicians, and completion of handovers would have prevented her death. Key lessons include: always reconcile medicines before admission, perform specified observations after sedation, accurately document patient behaviour, escalate medication concerns promptly, and ensure thorough documented handovers between clinical areas.
