A retrospectively and prospectively maintained clinical database at a single high\u2010volume EA\/TEF center was used for comparison. Patients treated between October 1, 2015 and July 31, 2022 were included. Searches progressively narrowed the cohort by ICD\u201010\u2010CM diagnosis codes, expansion to include incorrectly coded as \u2018iatrogenic, age less than 30 days, and use of at least 1 ICD\u201010\u2010CM procedure code. Results of PHIS data and institution data were compared for accuracy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The most refined search of PHIS and the EA\/TEF clinical database yielded 93 and 84 patients, respectively. The sensitivity was 99% and positive predictive value was 94%. A PHIS search using these methods and encompassing 49 children's hospitals yielded an EA\/TEF cohort of 2479 patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>We present a validated search method in the PHIS database to identify a high\u2010fidelity cohort of EA\/TEF patients for multi\u2010institutional study. We have demonstrated that a carefully maintained clinical database may be used to validate cohorts in PHIS. This cohort allows for improved practice variability and outcomes study of EA\/TEF patients. Similar methods may be employed to generate other rare disease cohorts in PHIS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of Evidence<\/jats:title><jats:p>Level 4.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ohn.839","type":"journal-article","created":{"date-parts":[[2024,5,28]],"date-time":"2024-05-28T08:34:06Z","timestamp":1716885246000},"page":"808-814","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Validation of a PHIS Esophageal Atresia and Tracheoesophageal Fistula Cohort in ICD\u201010"],"prefix":"10.1002","volume":"171","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0636-6233","authenticated-orcid":false,"given":"Claire M.","family":"Lawlor","sequence":"first","affiliation":[{"name":"Department of Otolaryngology Children's National Health System Washington District of Columbia USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ali","family":"Kamran","sequence":"additional","affiliation":[{"name":"Department of General Surgery Boston Children's Hospital Boston Massachusetts USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"Bennett","sequence":"additional","affiliation":[{"name":"Department of General Surgery Boston Children's Hospital Boston Massachusetts USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hengameh","family":"Behzadpour","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology Children's National Health System Washington District of Columbia USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Prasanth","family":"Pattisapu","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, Nationwide Children's Hospital The Ohio State University Columbus Ohio USA"},{"name":"Center for Surgical Outcomes Research and Center for Health Equity and Outcomes Research, Nationwide Children's Hospital Abigail Wexner Research Institute Columbus Ohio USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Benjamin","family":"Zendejas","sequence":"additional","affiliation":[{"name":"Department of General Surgery Boston Children's Hospital Boston Massachusetts USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5448-1546","authenticated-orcid":false,"given":"Sukgi S.","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology and Communication Enhancement Boston Children's Hospital Boston Massachusetts USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,5,28]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpedsurg.2022.01.060"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpedsurg.2021.06.015"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpedsurg.2016.08.012"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11605-017-3423-0"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpedsurg.2017.05.024"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00431-022-04677-4"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1186\/s13054-022-04293-6"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjoto.2023.103790"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/pbc.24930"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpedsurg.2013.02.062"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/lary.29798"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.surg.2014.03.016"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.2147\/PHMT.S106643"},{"key":"e_1_2_8_15_1","unstructured":"National Center for Health Statistics.
