Cardio-respiratory arrest due to mixed prescription drug sedation (clozapine and olanzapine) in the presence of advanced emphysema and acute bronchopneumonia
AI-generated summary
Nigel Douglas Roberts, a 55-year-old man with chronic schizophrenia, COPD, and cardiomyopathy, died from cardio-respiratory arrest due to mixed prescription drug sedation (clozapine and olanzapine) in the presence of advanced emphysema and acute bronchopneumonia. He was admitted to Spencer Clinic psychiatric inpatient unit following an assault on staff at Karingal nursing home. During his 23-hour hospital admission, he received multiple sedating medications (clozapine, olanzapam, clonazepam) for behavioural management. Critical clinical failures included: inadequate recognition of respiratory depression risk despite known COPD, lack of continuous oxygen saturation monitoring with pulse oximeter, insufficient respiratory rate monitoring, failure to exclude delirium as cause of agitation, vague observation orders, and absence of specialist respiratory input. The coroner found the death was otherwise preventable through strict respiratory monitoring protocols and careful medication risk assessment.

Nursing handovers in Spencer Clinic should be structured to include discussion regarding physical illness and observations
Process should be developed to ensure continuous training and up-skilling of clinical staff in basic life support, IV cannulation and other procedural skills
Formal mental health examination needs to be recorded for each mental health patient for each shift
Formal process should be developed with respect to registrar handover after hours and on weekends
System should be developed to improve case-specific and general discussion between nursing administration in Spencer Clinic and NWRH nursing specialist staff
NWRH should consult with Respiratory Department at Royal Hobart Hospital regarding adoption of oxygen prescription guideline for COPD
Processes should be developed to ensure direct admission patients are appropriately monitored with particular emphasis on patient safety and comprehensive evaluation within 24 hours of admission
State-wide system should be developed to ensure patients seen in Emergency Department have a complete medical assessment
Discussion should be instituted to align seclusion and restraint procedures initiated in Emergency Department with requirements of Mental Health Act 2013
