Cause of death

Bronchopneumonia and influenza A complicating cardiac and renal failure associated with mesangiocapillary glomerulonephritis complicating non-Hodgkin's lymphoma

AI-generated summary

A 66-year-old man with cryoglobulinaemic vasculitis secondary to non-Hodgkin's lymphoma died from bronchopneumonia and influenza A complicating cardiac and renal failure. He developed delirium, agitation and paranoia during his final admission, requiring an Inpatient Treatment Order. He received intramuscular olanzapine and opioid analgesia for behavioural management and pain. Clinical lessons include: recognising that hypoxia and CNS vasculitis can cause delirium in complex medical patients; considering respiratory depression risk when combining sedating medications in patients with compromised respiratory function; ensuring close monitoring of oxygen saturations and respiratory rate when medications with respiratory depressant potential are administered; and early recognition of occult infections like bronchopneumonia which may present atypically in unwell patients. The coroner found no criticism of medical management.

Contributing factors

  • Respiratory depression from combined medications (olanzapine, opioids, diazepam)
  • Hypoxia potentially contributing to delirium
  • Large pleural effusions causing pulmonary compression
  • Pulmonary oedema from cardiac and renal failure
  • Occult bronchopneumonia and influenza A not clinically recognised
  • CNS vasculitis causing delirium and behavioural disturbance
  • Delayed diagnosis due to patient refusal of procedures
