AI-generated summary
Melinda Miller, aged 58, died unexpectedly at home on 21-22 August 2013 while receiving treatment-resistant bipolar disorder management with clozapine and olanzapine. Her death was investigated thoroughly following detection of elevated drug levels at autopsy. However, these elevated levels were attributed to post-mortem redistribution rather than overdose, as medication was strictly supervised via daily dispensing by community mental health staff. Ms Miller had appropriate cardiometabolic monitoring while on clozapine. Autopsy revealed pre-existing myocarditis and atherosclerotic coronary artery disease. The coroner concluded the most likely cause of death was cardiac arrhythmia caused by the combination of pre-existing myocarditis and the acute action of clozapine and/or olanzapine. No healthcare professional was criticised, and all clozapine prescribing and monitoring protocols were appropriately followed. The key clinical lesson relates to improved post-mortem sampling procedures for patients on clozapine.

Coroner's recommendations
- Upon the death of a person who is administered clozapine, a blood sample should be taken immediately upon the admission of the body to the Royal Hobart Hospital and at multiple stages within a 48 to 72 hour period of time to more accurately determine levels of toxicity at the time of death.
- Implementation of Digital Medical Records in all community mental health clinics to improve information exchange between outreach clinics and the Clozapine Clinic.
