In the dataset review, we evaluated completeness, diversity, validation, and granularity in cancer clinical coding along the patient cancer pathway, which was split into three domains: (1) patient characteristics and risk factors, (2) cancer screening attendance, and (3) living with cancer. It was conducted in NCL primary care electronic health record systems, covering a population of over 1.4 million adults across 5 boroughs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Cancer-related clinical coding in NCL primary care revealed significant gaps despite high completeness for ethnicity (912,679\/1,055,083, 86.5%) and language (898,023\/1,307,601, 68.7%). Employment status (29,848\/1,229,644, 2.4%) and family history of cancer (183,424\/1,236,580, 14.8%) were underrecorded, with wide variation in coding practices. Screening data showed good alignment with national datasets for cervical and bowel screening but fragmented and inconsistent breast screening data due to a lack of standardized codes. Cancer diagnosis coding was incomplete (4604\/5260, 87.5% recorded), and treatment and staging data were almost entirely absent, limiting proactive management of long-term consequences. Stakeholder input highlighted inconsistent template use, limited data updates, and insufficient incentives as key barriers to better coding.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The QI project has provided a detailed insight into the many dimensions of cancer coding and sheds light on many factors that underpin variation and coding preference. We offer a number of recommendations. The prioritized ones include the need for a cancer clinical coding data framework for primary care supported by appropriate funding and incentivization; improvements in the breast screening pathway and its interface with primary care; improvements in the quality of secondary care information that is sent to primary care; and dissemination of the importance of coding of cancer activity in primary care.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2196\/73205","type":"journal-article","created":{"date-parts":[[2026,1,7]],"date-time":"2026-01-07T14:05:07Z","timestamp":1767794707000},"page":"e73205","source":"Crossref","is-referenced-by-count":0,"title":["Quality of Cancer-Related Clinical Coding in Primary Care in North Central London: Mixed Methods Quality Improvement Project"],"prefix":"10.2196","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2165-9192","authenticated-orcid":false,"given":"Afsana","family":"Bhuiya","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-8364-5084","authenticated-orcid":false,"given":"Graham","family":"Roberts","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7931-7101","authenticated-orcid":false,"given":"Katie","family":"Tucker","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7513-2575","authenticated-orcid":false,"given":"Stefanie","family":"Bonfield","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2676-5071","authenticated-orcid":false,"given":"Georgia","family":"Black","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2026,1,7]]},"reference":[{"key":"ref1","unstructured":"High quality patient recordsNHS England2025-01-06https:\/\/www.england.nhs.uk\/long-read\/high-quality-patient-records\/"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1136\/bmjspcare-2019-asp.135"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1186\/s12913-019-4326-4"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1186\/s12913-018-3745-y"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1136\/amiajnl-2013-001666"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1093\/fampra\/cmn023"},{"key":"ref7","unstructured":"Strategies for success: tackling common clinical documentation integrity challenges head-onHealthcare Financial Management Association20242025-09-01https:\/\/www.hfma.org\/revenue-cycle\/strategies-for-success-tackling-common-clinical-documentation-integrity-challenges-head-on\/"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijmedinf.2016.08.004"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1136\/bmjopen-2016-012669"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1136\/bmjopen-2021-051456"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.326.7398.1070"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.3399\/bjgp.2024.0036"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1007\/s00520-023-08278-1"},{"key":"ref14","unstructured":"National Cancer Registration and Analysis Service (NCRAS)GOV.UK2025-09-03https:\/\/www.gov.uk\/guidance\/national-cancer-registration-and-analysis-service-ncras"},{"key":"ref15","unstructured":"Datasets in support of statutory duties2025-09-08https:\/\/digital.nhs.uk\/services\/data-services-for-commissioners\/datasets-in-support-of-statutory-duties"},{"key":"ref16","unstructured":"Quality and Outcomes Framework (QOF)2024-09-30https:\/\/digital.nhs.uk\/data-and-information\/data-tools-and-services\/data-services\/general-practice-data-hub\/quality-outcomes-framework-qof"},{"key":"ref17","unstructured":"Navigating the New QOF Landscape: Your Guide to the 2025\/26 Changes for GP Practices2025-09-11https:\/\/www.mypracticemanager.co.uk\/advice\/qof-2025-26-changes"},{"issue":"3","key":"ref18","first-page":"143","volume":"15","author":"Tai, TW","year":"2007","journal-title":"Inform Prim Care"},{"key":"ref19","unstructured":"Cancer: find out more about the National Cancer Registration and Analysis Service (NCRAS) -
