Cancer registration data were linked to hospital data. Poisson regression was used to estimate adjusted risk ratios (adjRRs) that represent associations of patient characteristics with a cancer diagnosis 28 days after emergency admission.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among 28\u2009204 included women, 11\u2009377 (40.3%) were diagnosed after emergency admission. Being diagnosed after emergency admission was more common in younger (18\u201329 years: 42.7%, adjRR 1.36, 95%\u2009CI 1.22 to 1.52)\u2009and older women (\u226580 years: 54.9%, adjRR 1.25, 1.20 to 1.31), compared with women aged 60\u201369 years (36.2%). Women from the most deprived quintile of neighbourhoods had higher risks of being diagnosed after emergency admission (44.2%) than those from the least deprived quintile (37.8%, adjRR 1.11, 1.06 to 1.16). Women with severe frailty had substantially increased risks of being diagnosed after emergency admission (68.6%) than those who were fit (29.2%, adjRR 1.88, 1.78 to 1.99). Of the 8438\u2009women diagnosed after emergency admission, 1155 (13.7%) had early stage (stages 1 or 2) cancer, compared with 5442 (39.2%) of the 13\u2009865 not diagnosed after emergency admission.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Two in five women were diagnosed after emergency admission, with even higher frequencies seen in younger and older women, frailer women, and those from deprived neighbourhoods. Women diagnosed after emergency admission were three times less likely to have early stage cancer. These UK based results are likely to be relevant for many other countries that aim to reduce the number of women diagnosed with symptoms so severe that emergency admission is necessary.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1136\/bmjonc-2025-001053","type":"journal-article","created":{"date-parts":[[2026,7,8]],"date-time":"2026-07-08T00:00:10Z","timestamp":1783468810000},"page":"e001053","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["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"],"prefix":"10.1136","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5792-4747","authenticated-orcid":false,"given":"Georgia","family":"Zachou","sequence":"first","affiliation":[{"name":"Department of Health Services Research and Policy, London School of Hygiene and Tropical Medicine, London, UK"},{"name":"Clinical Effectiveness Unit, Royal College of Surgeons of England, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rui","family":"Wu","sequence":"additional","affiliation":[{"name":"Clinical Effectiveness Unit, Royal College of Surgeons of England, London, UK"},{"name":"School of Biosciences, University of Surrey, Guildford, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Hutchings","sequence":"additional","affiliation":[{"name":"Department of Health Services Research and Policy, London School of Hygiene and Tropical Medicine, London, UK"},{"name":"Clinical Effectiveness Unit, Royal College of Surgeons of England, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"van der Meulen","sequence":"additional","affiliation":[{"name":"Department of Health Services Research and Policy, London School of Hygiene and Tropical Medicine, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ipek","family":"Gurol-Urganci","sequence":"additional","affiliation":[{"name":"Department of Health Services Research and Policy, London School of Hygiene and Tropical Medicine, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Agnieszka","family":"Michael","sequence":"additional","affiliation":[{"name":"School of Biosciences, University of Surrey, Guildford, UK"},{"name":"Royal Surrey Cancer Centre, Royal Surrey County Hospital NHS Foundation Trust, Guildford, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sudha","family":"Sundar","sequence":"additional","affiliation":[{"name":"Department of Cancer and Genomic Sciences, University of Birmingham, Birmingham, UK"},{"name":"City Hospital, Sandwell and West Birmingham Hospitals NHS Trust, Birmingham, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2026,7,7]]},"reference":[{"key":"2026070717000556000_5.2.e001053.1","doi-asserted-by":"publisher","DOI":"10.3322\/CAAC.21834"},{"key":"2026070717000556000_5.2.e001053.2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ygyno.2012.06.033"},{"key":"2026070717000556000_5.2.e001053.3","doi-asserted-by":"crossref","DOI":"10.1186\/s12875-014-0200-y","article-title":"Estimating the workload associated with symptoms-based ovarian cancer screening in primary care: an audit of electronic medical records","volume":"15","author":"Lim","year":"2014","journal-title":"BMC Fam Pract"},{"key":"2026070717000556000_5.2.e001053.4","doi-asserted-by":"publisher","DOI":"10.1016\/S1470-2045(22)00127-9"},{"key":"2026070717000556000_5.2.e001053.5","doi-asserted-by":"publisher","DOI":"10.1016\/S1470-2045(24)00406-6"},{"key":"2026070717000556000_5.2.e001053.6","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(21)00731-5"},{"key":"2026070717000556000_5.2.e001053.7","unstructured":"Ovarian Cancer Audit Feasibility Pilot (OCAFP).
