Cause of death
intracerebral haemorrhage caused by rupture of arterial aneurysm
AI-generated summary
A 45-year-old man with an intracerebral haemorrhage from a ruptured aneurysm presented to an emergency department and general practice on multiple occasions in October 2005 with headache, vomiting, dizziness, and neck stiffness—features consistent with a sentinel bleed. Junior clinicians (a relatively inexperienced medical practitioner and an intern) misdiagnosed him with dehydration, migraine, and viral meningitis without performing appropriate investigations. Although the differential diagnosis of subarachnoid haemorrhage was briefly recorded, it was never properly excluded; instead, clinicians relied on positive response to analgesia and normal neurological examination. The patient was repeatedly discharged without CT or lumbar puncture despite clear red flags. He died from fatal rebleeding 6 weeks later. The death was preventable with timely imaging; had CT scanning been performed on first or second presentation, the aneurysm would likely have been identified with good prognosis for surgery.

Error types
Clinical conditions
Contributing factors
- failure to perform CT scan or lumbar puncture despite reasonable differential diagnosis of subarachnoid haemorrhage
- inexperienced junior clinicians (medical practitioner and intern) managing complex presentation
- inadequate documentation of headache onset characteristics
- reliance on response to analgesia as basis for excluding serious pathology
- failure to recognise atypical presentation of subarachnoid haemorrhage
- mischaracterisation of neck stiffness
- absence of senior medical officer review at critical time point
- previous clinical notes not made available at second presentation
- patient misdiagnosed sequentially as dehydrated, migrainous, and meningitic
Coroner's recommendations
- Minister for Health and South Australian Medical Board to draw Taylor, Gillam, and Farkas inquests to the attention of the medical profession with emphasis on education of GPs and ED practitioners regarding atypical presentations of subarachnoid and intracerebral haemorrhage
- Medical and nursing schools and Royal Australasian College of General Practitioners to include atypical presentations of subarachnoid and intracerebral haemorrhage in curricula, with particular reference to suddenness of headache onset
- Educational programs directed to medical practitioners (especially GPs and ED doctors, particularly junior staff) to: (a) properly investigate differential diagnoses of subarachnoid/intracerebral haemorrhage by appropriate means such as CT scans; (b) exercise care in eliminating these diagnoses on clinical examination alone; (c) exercise care in eliminating these diagnoses based on response to analgesia alone; (d) specifically consider atypical presentations; (e) consider sentinel bleed from aneurysm; (f) carefully elicit and document nature of headache onset; (g) consider circumstances of presentation and whether unusual for patient
- Modbury Hospital to amend 'Adult Non-Trauma Headache Treatment Guidelines' to include reference to atypical presentations of subarachnoid/intracerebral haemorrhage, characteristics including significance of headache onset nature, and specific reference to neck stiffness
- Modbury Hospital to create and install prompts in ED reminding practitioners to consider atypical presentations of subarachnoid/intracerebral haemorrhage
- Minister for Health to draw prompt recommendation to attention of all other hospitals and recommend implementation
- Modbury Hospital to ensure clinical records of patients are made available upon re-presentation
- Minister for Health to draw records availability recommendation to attention of all other hospitals and recommend implementation
- Modbury Hospital to ensure patients re-presenting to ED with same complaint are examined by senior medical practitioner and treatment plan not implemented without senior practitioner consultation
- Minister for Health to draw senior practitioner review recommendation to attention of all other hospitals and recommend implementation
