Acute on chronic subdural haematoma due to recent head trauma in the context of vascular dementia
AI-generated summary
Brian O'Connor, a 73-year-old man with vascular dementia, was admitted to a mental health inpatient unit following aggressive behaviour. He was placed on 15-minute observations due to Level 3 falls risk. Over several weeks, he sustained multiple head injuries from falls and altercations with other patients, including hits to his head on 1 and 2 February 2006. On 8 March 2006, he was struck on the head by another patient and became unresponsive. CT imaging revealed a 30mm acute-on-chronic subdural haematoma. He was intubated but his condition deteriorated, and he died on 15 March 2006. The coroner's findings suggest that despite identified falls risk and multiple head injuries, the cumulative risk was not adequately managed, and the development of chronic subdural haematoma was not detected earlier despite the pattern of repeated head trauma in an elderly patient on anticoagulation or with bleeding risk.
