The \u201cgold-standard\u201d definition was a blinded review of the abstracted chart by a neurology resident physician. Of the included 783 patients, 79 (10.1%) had diplopia as per the gold standard, while 51 (6.5%) had diplopia listed in NACRS. The specificity of the ICD-10 code was 96.9% (95% confidence interval 95.6\u201398.2), and sensitivity was 36.7% (26.1\u201347.3). The ICD-10 code for diplopia can reliably identify patients with true diplopia seen in the emergency departments.\n                  <\/jats:p>","DOI":"10.1017\/cjn.2026.10631","type":"journal-article","created":{"date-parts":[[2026,7,6]],"date-time":"2026-07-06T04:03:36Z","timestamp":1783310616000},"page":"1-4","source":"Crossref","is-referenced-by-count":0,"title":["Validation of an ICD-10 Code for Diplopia in the Emergency Department: A Retrospective Cohort Study"],"prefix":"10.1017","author":[{"given":"Alexander","family":"Thistle","sequence":"first","affiliation":[{"name":"University of Toronto Scarborough"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1196-3059","authenticated-orcid":false,"given":"Anuj","family":"Rastogi","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03dbr7087","id-type":"ROR","asserted-by":"publisher"}],"name":"University of Toronto & St. Michael\u2019s Hospital-Unity Health Toronto"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Clare L.","family":"Atzema","sequence":"additional","affiliation":[{"name":"Sunnybrook Health Sciences Centre & University of Toronto"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Moira K.","family":"Kapral","sequence":"additional","affiliation":[{"name":"University of Toronto"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert J.","family":"Campbell","sequence":"additional","affiliation":[{"name":"Queen\u2019s University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2953-2540","authenticated-orcid":false,"given":"Manav V.","family":"Vyas","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03dbr7087","id-type":"ROR","asserted-by":"publisher"}],"name":"University of Toronto & St. Michael\u2019s Hospital-Unity Health Toronto"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2026,7,6]]},"container-title":["Canadian Journal of Neurological Sciences \/ Journal Canadien des Sciences Neurologiques"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0317167126106313","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,14]],"date-time":"2026-07-14T06:36:46Z","timestamp":1784011006000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0317167126106313\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7,6]]},"references-count":0,"alternative-id":["S0317167126106313"],"URL":"https:\/\/doi.org\/10.1017\/cjn.2026.10631","relation":{},"ISSN":["0317-1671","2057-0155"],"issn-type":[{"value":"0317-1671","type":"print"},{"value":"2057-0155","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,7,6]]}}}
