A 30-year-old man with opioid use disorder, anxiety, and depression died by suicide from jumping the Batman Bridge. He had been prescribed escalating doses of clonazepam (1-8mg daily) over three years by general practitioners at Beaconsfield Family Medical Practice without documented risk assessments, risk mitigation strategies, or treatment plans. Critical omissions included: failure to access DORA (prescription monitoring system) despite alerts about his opioid dependence history; lack of collateral information gathering; absence of documented mental health monitoring despite reporting suicidal ideation to family; and no implementation of risk mitigation strategies such as urine drug screening or comprehensive reviews. While clonazepam did not directly cause his death, the coroner found that more thorough assessment and a structured treatment plan—rather than long-term benzodiazepine escalation—could have better identified his mental health and substance use issues. Clinicians must actively gather substance use history, implement documented safety plans, and use available monitoring systems when prescribing high-risk medications.

Coroner's recommendations
General practitioners prescribing benzodiazepines to patients with substance use disorder history should seek and obtain information concerning the patient's substance use history via DORA
Doctors should document clear goals of treatment with timeframes and expected undertakings, with such documentation available to all clinicians in the practice
Risk mitigation strategies should be implemented such as frequent urine drug screens, comprehensive patient reviews, and frequent full-bodied checks for signs of injecting
A plan should be implemented to prescribe the lowest effective dose of a benzodiazepine for the shortest possible time in line with correct therapeutic guidelines
Collateral information concerning a patient's mental health and substance use history should be actively sought
Comprehensive mental health assessment and monitoring should be documented, particularly when patients have disclosed suicidal ideation to family members
