Cause of death

pulmonary thromboembolism due to left deep calf vein thrombosis complicating left lower leg and pelvic fractures

AI-generated summary

John Matthew Murray, aged 35, died from pulmonary thromboembolism due to deep vein thrombosis complicating severe pelvic and leg fractures sustained in a motorcycle accident. Following extensive orthopaedic surgery, he was placed on a specialised three-times-daily heparin subcutaneous protocol designed to prevent post-operative thromboembolic disease. A junior doctor, Dr Hassan Hasan, systematically failed to administer correct heparin doses according to the protocol, increasing by 500 units instead of 1000 units on multiple occasions when APTT levels indicated underdosing. Despite protocol familiarity, lack of registrar supervision, and no single registrar assigned to oversee the intern, the errors went undetected for days. While causation could not be established with certainty, therapeutic anticoagulation was never achieved. The case demonstrates critical failures in intern supervision, unclear accountability structures, and inadequate monitoring of complex anticoagulation protocols in hospitals.

Contributing factors

  • failure by intern to administer correct heparin doses according to protocol
  • inadequate registrar supervision of junior doctor
  • lack of assigned registrar responsibility for specific intern
  • errors in heparin dosing not detected despite multiple opportunities
  • failure to achieve therapeutic anticoagulation despite protocol
  • period of 5 days (1-6 October) without thromboprophylaxis after severe trauma

Coroner's recommendations

  1. The Department of Health should advise surgeons visiting public hospitals that they are encouraged to contact the Forensic Science Centre to inquire as to the cause of death in cases where their patients have died and a post mortem has been directed by the Coroner
  2. The Royal Adelaide Hospital should conduct a review of the existing structure of the Orthopaedic Units to improve registrar supervision of interns and require that responsibility and accountability for the performance of a particular intern be reposed in a designated registrar
  3. The Medical Board of South Australia should consider these findings in relation to the registration of overseas trained doctors
