Ovarian cancer diagnosis within 28 days after an emergency admission to hospital: national population-based study of patient risk factors and cancer characteristics using routinely collected data in England.

Using national routinely collected data from England, this population-based study identifies patient and cancer characteristics linked to ovarian cancer diagnosis within 28 days of emergency admission. Two in five women were diagnosed after emergency admission, highlighting the need for targeted interventions to improve earlier diagnosis and outcomes. Emergency diagnosis was more common among younger and older women, those with greater frailty, and those from deprived neighborhoods. The national scope strengthens generalizability and shows how routine data can reveal populations and pathways where earlier recognition may be improved.
