John Walter Hedges, a 76-year-old man with terminal metastatic cancer, died at Greenslopes Private Hospital following a morphine overdose administered by agency nurse Cornelia Empen. Hedges had two pain management routes: an intrathecal catheter (delivering 2.2mg over 48 hours) and subcutaneous access (as-needed breakthrough pain relief). Empen, working her first shift in the ward with minimal orientation and inadequate handover, injected 5mg of morphine intended for the subcutaneous site into the intrathecal port instead. The bolus dose far exceeded normal intrathecal administration and precipitated respiratory depression and death. Systemic failures included unlabeled infusion lines, lack of mandatory bedside verification by two nurses, insufficient agency staff orientation, inadequate handover clarity, and absence of readily available reversal agents. The coroner found systemic rather than criminal negligence, identifying key preventive measures: line labeling, safety alerts, mandatory bedside handovers, improved orientation procedures, and antidote availability.
