Patients with VLU are often admitted to the hospital; however, epidemiological study of this important patient subset is challenged by lack of validated database search protocol. Five International Classification of Diseases (ICD) 9 codes were identified for their relationship with VLUs (454.0, 454.2, 459.11, 707.9, and 707.10). The ICD9 code was considered to successfully predict a VLU if the wound was located in the gaiter area and had either relevant clinical findings, a positive venous study, and\/or a diagnosis of VLU written in the physician note. The code 454.0, when combined with length of admission and subjects\u2019 age, yielded high specificity (100%) and positive predictive value (100%), sacrificing sensitivity (34.4%). This formula represents a viable search criterion to identify VLU patients in large\u2010scale datasets to examine patients\u2019 outcomes, costs, and comorbidities.<\/jats:p>","DOI":"10.1111\/wrr.12700","type":"journal-article","created":{"date-parts":[[2019,1,28]],"date-time":"2019-01-28T22:28:22Z","timestamp":1548714502000},"page":"431-434","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Validation of inpatient international classification of disease ninth revision codes as predictors of venous leg ulcers"],"prefix":"10.1111","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8394-3503","authenticated-orcid":false,"given":"J.A.","family":"Jaller","sequence":"first","affiliation":[{"name":"Department of Dermatology and Cutaneous Surgery University of Miami Miller School of Medicine  Miami Florida"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.S.","family":"Darwin","sequence":"additional","affiliation":[{"name":"Department of Dermatology and Cutaneous Surgery University of Miami Miller School of Medicine  Miami Florida"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.I.","family":"Silverberg","sequence":"additional","affiliation":[{"name":"Department of Dermatology Northwestern University Feinberg School of Medicine  Chicago Illinois"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.A.","family":"Lev\u2010Tov","sequence":"additional","affiliation":[{"name":"Department of Dermatology and Cutaneous Surgery University of Miami Miller School of Medicine  Miami Florida"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2019,2,7]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2014.10.048"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2648.2010.05568.x"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.3111\/13696998.2014.903258"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1067\/mjd.2002.121739"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2016.12.043"}],"container-title":["Wound Repair and Regeneration"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fwrr.12700","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/wrr.12700","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/wrr.12700","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/wrr.12700","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,10]],"date-time":"2023-09-10T21:39:57Z","timestamp":1694381997000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/wrr.12700"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,2,7]]},"references-count":5,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2019,7]]}},"alternative-id":["10.1111\/wrr.12700"],"URL":"https:\/\/doi.org\/10.1111\/wrr.12700","archive":["Portico"],"relation":{},"ISSN":["1067-1927","1524-475X"],"issn-type":[{"value":"1067-1927","type":"print"},{"value":"1524-475X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,2,7]]},"assertion":[{"value":"2018-07-28","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2019-01-23","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2019-02-07","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
