AI-generated summary

Katherine Walton, a 47-year-old registered nurse, died from insulin overdose in April 2007. She had a complex medical history including hepatitis C, depression, chronic back pain, epilepsy, and substance use issues. After an argument at home on 23 April, she was assessed at Wonthaggi Hospital for suspected overdose and given a deferred psychiatric assessment. She discharged herself early the next morning, visited her workplace and solicitor, then checked into a Melbourne hotel where she died. The coroner found she deliberately self-administered insulin. Key clinical lessons include: recognition that early discharge after overdose risk warrants closer follow-up, importance of comprehensive psychiatric risk assessment in emergency settings, attention to medication access in workplace settings, and identification of cumulative psychosocial stressors (occupational loss, bereavement, relationship strain) requiring integrated mental health support.
