AI-generated summary
Harriet Ostler, a 19-month-old toddler, was admitted to Port Macquarie Base Hospital with viral respiratory symptoms and died from sudden cardiac death due to underlying myocarditis/cardiomyopathy precipitated by rhinovirus infection. Clinical lessons include: (1) recognising that pulmonary consolidation on chest X-ray can indicate cardiac pathology with fluid overload, not just infection; (2) interpreting abnormal vital signs (respiratory rate >70, elevated heart rate) as requiring escalation despite fever; (3) the importance of blood gas sampling when vital signs deteriorate; (4) implementing Between the Flags vital sign monitoring systems to trigger medical review; and (5) establishing clear escalation pathways rather than vague instructions. The coroner noted the underlying cardiac pathology was not recognised. Whilst an abnormal blood gas or correct CXR interpretation might have prompted investigation, whether earlier recognition would have prevented sudden cardiac arrest remains unclear given the rapid deterioration.

Contributing factors
- viral myocarditis/cardiomyopathy secondary to rhinovirus
- failure to recognise underlying cardiac pathology
- misinterpretation of chest X-ray findings
- failure to perform blood gas analysis despite deteriorating vital signs
- failure to escalate care to higher level of care
- lack of explicit vital sign thresholds for medical review
- inadequate recognition of clinical deterioration between 11:09pm and 12:47am
- failure to access Between the Flags system for vital sign interpretation
- transition to electronic medical record system without adequate safety checks
