AI-generated summary

A 39-year-old man with chronic paranoid schizophrenia on a Community Treatment Order died by suicide in a head-on motor vehicle collision. He had been appropriately managed on depot antipsychotic medication with generally good psychiatric care. However, a critical gap occurred when his GP (Dr C.), lacking awareness of psychiatrist-only requirements for commercial licence assessments and unaware of recent medication non-compliance, certified him as fit for a commercial truck driver's licence—a task requiring psychiatric assessment per guidelines. The psychiatrist (Dr A.) had appropriately declined the commercial licence weeks earlier due to concerns about stability and community safety. Although this certification error did not directly cause the death (the deceased was not driving a truck when he died), it highlights systemic failures: inadequate communication between GP and psychiatrist about the fitness-to-drive assessment, unclear guidance to GPs about specialist requirements, and insufficient flagging on assessment forms. Clinically, this case underscores the importance of inter-specialist communication, adherence to assessment guidelines, and recognising that recent psychiatric instability, medication non-compliance, and poor insight are contraindications for high-responsibility roles.

Coroner's recommendations

  1. Department of Transport should be informed that medical assessment certificates are being accepted for commercial driving that have not been certified by appropriately qualified professionals as specified in guidelines
  2. Department of Transport should consider altering the fitness-to-drive assessment form to make the requirement for psychiatric certification of commercial applications clearer
  3. Royal Australian College of General Practitioners (RACGP) should provide guidance to members about the requirement for specialist psychiatric opinion in relation to commercial driver's licence applications
  4. General practitioners should take the initiative to enquire with treating psychiatric teams when assessing fitness to drive for patients under specialist psychiatric care
  5. Encourage review and clarification of fitness-to-drive guidelines by relevant professional bodies to address ambiguities in assessment criteria
