We assessed the validity of hospital episode data for identifying individuals with chronic kidney disease compared to biochemistry data in a large population-based cohort, the Grampian Laboratory Outcomes, Morbidity and Mortality Study-II (n\u2009=\u200970,435). Grampian Laboratory Outcomes, Morbidity and Mortality Study-II links hospital episode data to biochemistry data for all adults in a health region with impaired kidney function and random samples of individuals with normal and unmeasured kidney function in 2003. We compared identification of individuals with chronic kidney disease by hospital episode data (based on International Classification of Diseases-10 codes) to the reference standard of biochemistry data (at least two estimated glomerular filtration rates &lt;60\u2009mL\/min\/1.73\u2009m<jats:sup>2<\/jats:sup> at least 90\u2009days apart). Hospital episode data, compared to biochemistry data, identified a lower prevalence of chronic kidney disease and had low sensitivity (&lt;10%) but high specificity (&gt;97%). Using routine health care data from multiple sources offers the best opportunity to identify individuals with chronic kidney disease. <\/jats:p>","DOI":"10.1177\/1460458214562286","type":"journal-article","created":{"date-parts":[[2015,1,1]],"date-time":"2015-01-01T04:33:08Z","timestamp":1420086788000},"page":"383-396","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["Is routine hospital episode data sufficient for identifying individuals with chronic kidney disease?
