Hypoglycaemia due to administration of exogenous insulin
AI-generated summary
Mitchell Johns, 28, died from hypoglycaemia following an intentional insulin overdose during a suicide attempt. He had Type 1 diabetes, depression, and chronic suicidal ideation. On 27 May 2021, he presented to Bendigo Hospital ED after injecting ten insulin pens. Mental health assessment occurred but systems failures limited decision-making. He discharged against medical advice, re-presented hours later with recurrent hypoglycaemia, and discharged again that evening despite medical risks. He died the next morning from ongoing insulin effects. Key clinical lessons: (1) Failure to integrate medical and mental health planning resulted in clinicians lacking shared risk information; (2) Inadequate mental state re-assessment on second ED admission despite clear indicators; (3) No formal escalation pathways for mental health concerns between teams; (4) Absence of written discharge instructions to his father regarding risk monitoring and insulin safety. The coroner found the death potentially preventable and recommended improved integration of care, clearer assessment order guidance for emergency physicians, and statewide education on managing concurrent medical-mental health crises.
