Cause of death

Cardiac conducting system disease leading to asystole against a background of a structurally abnormal heart and a congenital cluster of disorders

AI-generated summary

A 24-year-old woman with complex congenital cardiac disease, cerebral palsy, and hydrocephalus was admitted to a secondary hospital with a respiratory tract infection and bradycardia with left bundle branch block. She deteriorated into asystole during overnight monitoring. Cardiac telemetry alarms sounded for approximately 25-30 minutes but nursing staff failed to respond appropriately. While the underlying cardiac conducting system disease was the direct cause of death, the delayed response to telemetry alarms represented a lost opportunity for resuscitation and potential temporary pacing intervention. Key failures included: inadequate supervision of junior medical staff regarding management planning; failure to chart prescribed antibiotics; alarm fatigue and demarcation culture among nursing staff; understaffing (two RNs and one EN for 30 beds); and equipment issues with telemetry batteries. Although experts agreed early intervention would have been difficult given rapid deterioration, prompt response was the standard of care expected.

Contributing factors

  • Left bundle branch block with progressive bradycardia
  • Failure of nursing staff to respond to extended red telemetry alarm for 25-30 minutes
  • Alarm fatigue from frequent false alarms due to faulty batteries
  • Culture of demarcation among nursing staff; individual staff only attending to allocated patients
  • Inadequate staffing levels: 2 registered nurses and 1 enrolled nurse for 30-bed ward
  • Late arrival of assistant in nursing, overloading enrolled nurse
  • Failure of monitor at nurses' station in front of beds 1-4
  • Inadequate supervision of junior medical staff by visiting medical officer
  • Failure to chart prescribed antibiotics as regular medication
  • Deficiency in medical intervention guidelines for cardiac dysrhythmia management
  • Underlying viral respiratory infection precipitating cardiac decompensation
  • Complex congenital cardiac disease with patent ductus arteriosus, valvular degeneration, and global systolic dysfunction

Coroner's recommendations

  1. Registered Nurse Nomsebenzi Mbedla and Registered Nurse Julie Kang be referred pursuant to s.82(2) of the Coroners Act 2009 and s.151A of the Health Practitioner Regulation National Law (NSW) No 86a of 2009
