AI-generated summary
Joshua Brown, a 57-year-old man with treatment-resistant schizophrenia managed in the community, died from clozapine toxicity. He had accumulated over 50 tablets of clozapine at home despite being prescribed 550mg daily in blister packs. On 20 April 2017, his case manager noted disorientation and confusion during a telephone call and attempted to escalate concerns to the Waiora mental health team. However, communication breakdown occurred when reception staff and the duty worker failed to follow escalation protocols, delaying notification to his case manager. Mr Brown was found deceased two days later with evidence of excessive clozapine ingestion. The coroner found he was experiencing psychosis at the time. Key clinical lessons: vigilance about clozapine stockpiling, especially during non-compliance episodes; regular assessment of excess medication access; patient counselling about medication disposal; and reliable escalation processes for urgent clinical concerns in community mental health settings.
