Cause of death

morphine toxicity and carcinomatosis

AI-generated summary

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.

Contributing factors

  • injection of 5mg morphine into intrathecal port instead of subcutaneous catheter
  • unlabeled infusion lines
  • failure of second nurse to accompany to bedside for verification
  • minimal orientation of agency nurse to hospital
  • unclear handover due to foreign accent on recorded message
  • similar appearance of two infusion sites without clear differentiation
  • flawed hospital procedures for agency staff familiarization
  • absence of readily available naloxone prior to incident
  • lack of safety alerts or visual identifiers on infusion equipment

Coroner's recommendations

  1. Implement labeling of intrathecal lines to clearly distinguish them from subcutaneous access
  2. Discontinue use of infusion lines with side ports
  3. Attach safety alert cards to pumps to remind staff of intrathecal line presence
  4. Mandate bedside handovers rather than recorded tape handovers
  5. Ensure naloxone is available on all emergency trolleys throughout the hospital
  6. Review and improve procedures for orienting agency nurses to hospital policies and practices
  7. Enhance continuing education programs to include case studies of critical incidents
  8. Implement auditing processes to monitor compliance with hospital policies
  9. Ensure mandatory verification by two nurses at bedside before administration of high-risk medications
  10. Provide specialized orientation for nurses unfamiliar with intrathecal medication delivery systems
