Despite being a major source of morbidity and mortality for this patient population, a nationwide, systematic mechanism for reporting of brain metastases does not exist. Better understanding the epidemiology of brain metastases will help identify individuals who are at greatest risk of developing them and guide clinicians in selecting patients who are most likely to benefit from brain metastasis surveillance and prophylaxis.Objective Men who experience homelessness in Australia often have complex health and social issues, including the trimorbidity of concurrent mental illness, substance use disorders and physical health conditions. These men tend to have poor health outcomes, and present challenges to healthcare systems. To improve system responsiveness and patient outcomes, the perspectives of marginalised groups need to be understood. Methods Five focus groups were conducted with 20 men in a homeless men's hostel, exploring their experiences of seeking and receiving health care, and views about improving these. An inductive thematic analysis was undertaken. Results Several participants expressed gratitude for care provided for life-threatening physical illness and trauma. However, negative experiences of health system responses were more frequently reported. Four emerging themes all made securing effective 'tickets of entry' to health care more difficult dismissive care, care fragmentation, inconsistent medical management of arginalised people, to break cycles of trauma and exclusion. Prehospital intramuscular (IM) ketamine is increasingly used for chemical restraint of agitated patients. However, few studies have assessed emergency department (ED) follow-up of patients receiving prehospital ketamine for this indication, with previous reports suggesting a high
