Cause of death

multi-organ failure and staphylococcal septicaemia following pulmonary and aortic valve replacement for staphylococcal endocarditis of the aortic valve

AI-generated summary

A 41-year-old man with a pre-existing aortic valve abnormality developed staphylococcal septicaemia, likely initiated by Q fever exposure at his abattoir workplace or a finger laceration. He presented with fever and chest pain but was initially misdiagnosed as having viral infection. Following appropriate blood tests revealing thrombocytopenia, he was admitted to RAH. He absconded after 24 hours, returning to the community in a delirious state due to sepsis-induced acute organic brain syndrome. He was appropriately detained under the Mental Health Act to ensure treatment, re-admitted to RAH, and underwent emergency aortic and pulmonary valve replacement. Despite technically successful surgery, he suffered extensive myocardial infarction, multi-organ failure and died. Clinical lessons: early recognition of sepsis severity, appropriate use of mental health legislation for acute delirium secondary to medical illness, and timely escalation to cardiothoracic surgery. Vaccination of at-risk workers with pre-existing cardiac pathology warrants consideration.

Contributing factors

  • pre-existing aortic valve abnormality
  • Q fever exposure (likely occupational from abattoir work)
  • finger laceration at work providing potential source of infection
  • possible intravenous drug use as source of infection
  • initial misdiagnosis as viral infection rather than sepsis
  • patient absconded from hospital after 24 hours before antibiotic regimen established
  • acute delirium secondary to sepsis causing treatment refusal
  • extensive myocardial infarction and multi-organ failure post-operatively

Coroner's recommendations

  1. The South Australian Department of Health should reinforce its existing recommendations regarding immunisation of persons who have animal contact in the course of their occupations, particularly those with known existing cardiac valve irregularity, against Q fever.
