AI-generated summary
Terry Riordan, 45, died from multi-drug toxicity caused by ingesting amitriptyline and methadone in April 2015. He had complex medical and psychiatric comorbidities, substance abuse issues, and was under care of his GP Dr H. for 17 years. Critical clinical lessons include: inadequate medical record-keeping failing to document consultation notes, clinical reasoning, medication decisions, suicide risk assessments, or referrals; concurrent prescribing of multiple psychoactive medications without specialist input (three antidepressants simultaneously, two benzodiazepines); failure to assess risk from polypharmacy; and lack of structured mental health care planning despite known suicidal ideation. Dr H. failed to refer to psychiatry, pain specialists, or drug/alcohol services despite complexity. The mental health team (RCNACS) performed appropriately and offered voluntary admission which Terry declined. Police response to welfare check was reasonable given circumstances.
