Cause of death

Acute hypoxic ischaemic encephalopathy and pneumonia in a man with recent traumatic neck injury and combined drug effect (principally Oxycodone)

AI-generated summary

Peter Martin Carroll, age 21, died on 8 June 2007 in the ICU at Royal Perth Hospital from acute hypoxic ischaemic encephalopathy and pneumonia following oxycodone overdose. He had been discharged that day (5 June) after orthopaedic surgery for a wrist fracture sustained while intoxicated. Carroll had a documented psychiatric history including recent involuntary mental health admission (discharged 27 May 2007) for attempted suicide, chronic alcohol abuse, depression, and psychosis. Critically, physicians at Royal Perth Hospital did not access discharge summaries from the Joondalup Health Campus mental health unit due to system access restrictions. A brief assessment by drug and alcohol nursing staff on discharge day was inadequate—no formal psychiatric review occurred despite clear risk factors for self-harm. Carroll was discharged with 20 × 20mg oxycodone tablets. That evening he consumed a fatal dose. The coroner found the death accidental, noting systemic failures in information sharing between hospitals and inadequate mental health risk assessment before discharge of a vulnerable young man to hostel accommodation.

Contributing factors

  • Failure to access mental health discharge summaries from Joondalup Health Campus due to PSOLIS system restrictions
  • Inadequate psychiatric risk assessment prior to discharge
  • Absence of formal mental health review despite documented recent involuntary psychiatric admission and suicide attempts
  • Discharge with potentially fatal quantity of oxycodone to vulnerable patient with high risk factors: recent suicidal ideation, active psychiatric illness, substance abuse history, and hostel accommodation without secure storage
  • Misinterpretation of drug and alcohol nursing assessment as constituting comprehensive psychiatric review
  • Inadequate documentation clarity regarding type of assessment performed
  • Lack of integration between public hospital PSOLIS system and private Joondalup Health Campus mental health records

Coroner's recommendations

  1. No formal recommendation regarding PSOLIS system access made by coroner as active steps already underway; however coroner noted the inability of appropriately credentialed physicians at Joondalup Health Campus to fully access and upload relevant patient information was sub-optimal and in need of revision; implementation expected early 2013
