AI-generated summary
Candice Mackenzie Wallace-Mohlmann, a 30-year-old woman with chronic schizophrenia and substance abuse history, died from hypoxic brain injury caused by self-injection of vecuronium and atropine obtained from a hospital storeroom. She was admitted under Mental Health Act detention for acute psychosis. Critical clinical lessons include: (1) her antipsychotic medication was inadequate despite florid psychosis; (2) she required one-to-one nursing observation but was managed at lower observation levels; (3) critical clinical information (including her morning absconding) was not communicated to afternoon staff, who relied on incomplete verbal handovers rather than reading clinical records; (4) transfer from secure psychiatric intensive care to an open ward without intensive supervision was inappropriate for her clinical acuity; (5) emergency medication trolleys in Ward B4 were inadequately secured. The coroner found the death was not suicide but recreational drug-seeking behavior reflecting institutional restrictions and inadequate psychiatric containment.

- Inadequate antipsychotic medication dosing (sodium valproate subtherapeutic levels, flupenthixol dose not escalated despite florid psychosis)

- Poor communication of clinical information between shifts; reliance on incomplete verbal handover rather than review of clinical records
- Nursing staff unaware of patient's morning absconding episode
- Inappropriate transfer from secure psychiatric intensive care unit (North Brentwood) to open ward without adequate supervision
- Inadequate security of emergency medication trolley containing dangerous drugs
- Lack of contemporaneous clinical documentation following intake meeting
- Patient's clinical condition deteriorated (floridly psychotic) yet low-level observation continued
- Institutional pressure to use open wards for high-acuity patients due to downsizing of psychiatric hospitals
