It is uncertain to what extent this is done in primary care and whether testing is equitable.<\/jats:p>\n <\/jats:sec>\n \n Aim<\/jats:title>\n To report the proportion of people with incident heart failure who undergo a ferritin test within 12 months.<\/jats:p>\n <\/jats:sec>\n \n Design & setting<\/jats:title>\n Retrospective primary care cohort study using Clinical Practice Research Datalink Aurum data, between 2016 and 2021.<\/jats:p>\n <\/jats:sec>\n \n Method<\/jats:title>\n We report the proportion of adults with an incident diagnosis of heart failure who received a ferritin test within 12 months. Multivariable logistic regression was used to examine the odds of testing based on key demographic covariates and co-morbidities.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Among 105 749 individuals with an incident diagnosis of heart failure (mean age 71.6 years, SD 14.3), only 35 688 (33.7%) received a ferritin test within the subsequent year. Increasing age (odds ratio 1.25 per 10-year increase, 95% CI: 1.24\u20131.27), female sex (male sex OR 0.86, 0.84\u20130.89) and Asian ethnicity (OR 1.70, 1.59\u20131.80) were all associated with increased odds of testing as were diagnoses of coeliac disease (OR 1.86, 1.58-2.21), type 1 diabetes (OR 1.82, 1.51-2.19) and cirrhosis (OR 1.64, 1.43-1.87). There was geographic variation in testing, even in adjusted analyses.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n In a large primary care dataset, two thirds of people with incident heart failure did not receive a ferritin test for iron deficiency within a year of diagnosis demonstrating a gap in current practice and an opportunity for improvements in service delivery.<\/jats:p>\n <\/jats:sec>","DOI":"10.3399\/bjgpo.2026.0086","type":"journal-article","created":{"date-parts":[[2026,7,31]],"date-time":"2026-07-31T15:50:15Z","timestamp":1785513015000},"page":"BJGPO.2026.0086","source":"Crossref","is-referenced-by-count":0,"title":["Iron deficiency testing among people with incident heart failure in primary care"],"prefix":"10.3399","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-7162-7695","authenticated-orcid":false,"given":"Vijay","family":"Maharajan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0352-3785","authenticated-orcid":false,"given":"Nicholas Robert","family":"Jones","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1588-3849","authenticated-orcid":false,"given":"Clare","family":"Bankhead","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Innocent","family":"Erone","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Haynes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4982-0291","authenticated-orcid":false,"given":"Alvin M","family":"Katumba","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christien Ka Hou","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suzanne","family":"Maynard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Noemi","family":"Roy","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akshay","family":"Shah","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simon J","family":"Stanworth","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0946-742X","authenticated-orcid":false,"given":"Margaret","family":"Smith","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cynthia","family":"Wright-Drakesmith","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1987","published-online":{"date-parts":[[2026,7,31]]},"container-title":["BJGP Open"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.3399\/BJGPO.2026.0086","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,31]],"date-time":"2026-07-31T15:50:16Z","timestamp":1785513016000},"score":1,"resource":{"primary":{"URL":"http:\/\/bjgpopen.org\/lookup\/doi\/10.3399\/BJGPO.2026.0086"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7,31]]},"references-count":0,"alternative-id":["10.3399\/BJGPO.2026.0086"],"URL":"https:\/\/doi.org\/10.3399\/bjgpo.2026.0086","relation":{},"ISSN":["2398-3795"],"issn-type":[{"value":"2398-3795","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,7,31]]}}}
