Unascertained - sudden and unexpected death; evidence did not allow determination between sudden unexpected death in epilepsy (SUDEP) and sudden cardiac death (SCD)
AI-generated summary
Ezekiel Howard, a 10-year-old boy, died suddenly in his sleep on 12 September 2011. His death remains unexplained despite extensive investigation. The coroner could not determine whether death resulted from undiagnosed epilepsy (SUDEP) or sudden cardiac death, as evidence was incomplete and inconclusive. The boy had episodes of transient neurological symptoms in April-May 2011 that prompted investigation including ECG, MRI, and echocardiogram, but no definitive diagnosis was established. An EEG was recommended but not completed before his death. Post-mortem examination revealed subtle cardiac inflammation and minor brain findings but no definitive cause. Critical learning: the importance of completing diagnostic workup in children with unexplained neurological episodes, the challenge of diagnosing focal epilepsy without specialist input and EEG, and the necessity of proper medical records management. A particularly concerning systemic failure involved deletion of his echocardiogram images by the hospital's ultrasound equipment system.

Coroner's recommendations
The coroner emphasized the importance of retention of original medical images and noted that robust systems for secure data storage should be mandatory in all Local Health Districts
Highlighted the need for immediate and thorough investigation when large volumes of medical data are lost
Recommended clear written protocols regarding data retention, archiving, and deletion procedures for all medical equipment, particularly when used by visiting clinicians
Noted the importance of completing diagnostic workup (including EEG) in children with unexplained neurological symptoms
Emphasized the critical role of specialist paediatric neurologists in diagnosing childhood epilepsy, ideally with witness accounts or video footage of events
Recommended improved access to EEG testing for families in outer suburban areas
