Cause of death

Septic arthritis complicating left knee joint prosthesis in the setting of status post fractured neck of femur and Girdlestone procedure

AI-generated summary

A 62-year-old man with autism spectrum disorder, cerebral palsy, and epilepsy died from septic arthritis of a prosthetic left knee joint. He presented with fever, knee pain, and delirium in November 2022, three months post-knee replacement. Despite clinical suspicion of prosthetic joint infection, the orthopaedic team repeatedly decided against joint aspiration, citing concerns about introducing infection—a concern the coroner found unreasonable given he was already on antibiotics with negative blood cultures. The team also failed to diagnose a hip fracture after he fell from his bed. Intellectual disability and delirium complicated assessment, but the coroner found the death preventable because earlier aspiration and diagnosis would likely have altered outcomes. Key failures included: not performing the planned aspiration despite no alternative infection source, inadequate multidisciplinary consultation, and delayed hip fracture diagnosis. The coroner found empirical evidence shows joint aspiration carries minimal infection risk (0.037-0.08%) and is far outweighed by risks of missing septic arthritis.

Contributing factors

  • Failure to perform joint aspiration despite clinical suspicion of prosthetic joint infection
  • Reluctance to aspirate knee based on unreasonable fear of introducing infection
  • Failure to identify alternative infection sources in timely manner
  • Inadequate multidisciplinary team discussion and consultation
  • Delayed diagnosis of right hip fracture following fall from bed
  • Intellectual disability and delirium complicating clinical assessment and history-taking
  • Incomplete examination following unwitnessed fall
  • Misinterpretation of chest x-ray findings
  • Failure to perform planned aspiration procedure

Coroner's recommendations

  1. Grampians Health conduct a review of circumstances surrounding the death to produce guidelines for staff regarding assessment and management of patients with disability, cognitive impairment, mental health conditions, or other factors contributing to difficult, unreliable or inconsistent clinical assessment, particularly relating to patient history-taking and physical examination
  2. Grampians Health conduct a review of scientific literature on risk of iatrogenic complications of diagnostic joint aspiration and produce evidence-based guidelines, developed at multidisciplinary consultant level, to balance risk of complication with risk of missing joint infection diagnosis in septic patients where joint infection may be implicated
