AI-generated summary

John Laurenson, a 47-year-old remand prisoner, died from rupture of a brain aneurysm on 20 June 2017, four days after collapsing in his prison cell. He had multiple intracranial aneurysms identified in 2015-2016, including a 23mm aneurysm. Multiple opportunities to provide earlier specialist treatment were missed: Canberra Hospital failed to arrange follow-up after discovering the aneurysms; during his first imprisonment (May-September 2016), Justice Health did not initiate specialist referral despite having medical records; during his second imprisonment, a GP incorrectly referred him to vascular rather than neurosurgery, delaying urgent neurosurgical consultation by four months; the MDT at Prince of Wales Hospital lacked critical information about aneurysm growth (2015 scans unavailable) that would have triggered urgent treatment. Expert evidence indicated earlier intervention may have prevented the fatal haemorrhage. Systemic failures in medical record management, specialist referral processes, and information gathering contributed to delays in diagnosis and treatment.

Contributing factors

  • failure of Canberra Hospital to arrange neurosurgical follow-up after identifying serious aneurysms
  • failure to initiate specialist referral during first imprisonment (May-September 2016)
  • incorrect specialist referral (vascular instead of neurosurgery) by GP Dr Mayer in November 2016
  • absence of 2015 neuroradiology imaging at MDT meeting on 14 March 2017
  • incomplete patient history obtained at outpatient clinic (failure to detect known hypertension)
  • absence of serial imaging comparison to assess aneurysm growth
  • inadequate clinical handover and information transfer between healthcare systems
  • delay of four months between initial referral and neurosurgical consultation
  • systemic failures in medical record management across different healthcare jurisdictions
  • insufficient documentation of MDT decision-making and imaging reviewed

Coroner's recommendations

  1. Justice Health and Forensic Mental Health Network consider introducing a policy requiring that where an inmate has a known brain aneurysm, or where a brain aneurysm is identified during an inmate's period of custody, the inmate is referred to a GP Clinic as soon as possible and then referred for urgent review by a specialist neurosurgeon
