AI-generated summary
Michelle McIlquham, 28 years old, died from undiagnosed acute bacterial meningitis (streptococcus pneumonia) that developed from a middle ear infection. She presented to Bankstown Hospital Emergency Department with a first-time seizure, fever, severe headache and ear pain. Despite multiple clear danger signs and repeated nursing escalations of concern, the junior doctor diagnosed only otitis media with behavioral distress, completely failing to consider serious life-threatening illness. No blood tests or CT imaging were ordered to investigate further. She was inappropriately discharged while clearly unwell and requiring physical assistance. She died at home within 7 hours. Critical system failures included: the supervising senior doctor accepted the junior's diagnosis without examining the patient; no standard investigations were ordered; parental and nursing concerns were not adequately heeded; cognitive bias (premature closure) caused the doctor to anchor to an initial wrong impression; and staff fatigue likely impaired judgment. The case powerfully demonstrates how developmentally disabled patients are vulnerable when their symptoms and distress are misattributed to behavioral issues rather than investigated as serious medical illness.

Coroner's recommendations
- Nursing assessment of all high-risk patients triaged categories 1-3 before physical discharge from ED if not assessed within 30 minutes of last review
- Nursing assessment of patients requiring physical assistance to leave ED, or amendment of discharge protocols to warn against discharging patients needing physical assistance without doctor assessment
- Guideline requiring senior doctor assessment of patients presenting with first-time seizure, with FBC and standard battery of tests ordered if senior doctor unavailable within 30 minutes
- GCS assessment on admission and prior to discharge for all patients presenting with GCS less than 15
- Senior doctor assessment of patients with developmental disability in triage categories 1, 2 and 3 before discharge
- Annual education of all ED clinical staff on detection of signs of risk factors and symptoms of sepsis, including investigations and management with rapid IV antibiotics and fluids
- Documentation of junior medical officer's differential diagnosis in patient record, formulated at time of Presentation Plan
- Review of Section 1 (Emergency Department Patient Assessment and Review) of Bankstown Hospital Emergency Department Supervision Guideline
- In-house training for ED staff (medical and nursing) on mental and physical preparation for shifts and self-care during shifts
