We evaluated the sensitivity, specificity, accuracy, and agreement of the NHIS criteria for defining T2DM by comparing them with the KNHANES criteria as a standard reference.Results: In the study population (n=13,006), two algorithms were devised to determine from the NHIS dataset whether the diagnostic claim codes for T2DM were accompanied by prescription codes for anti-diabetic drugs (algorithm 1) or not (algorithm 2). Using these algorithms, the prevalence of T2DM was 14.9% (n=1,942; algorithm 1) and 20.8% (n=2,707; algorithm 2). Good reliability in defining T2DM was observed for both algorithms (Kappa index, 0.73 [algorithm 1], 0.63 [algorithm 2]). However, the accuracy (0.93 vs. 0.89) and specificity (0.96 vs. 0.90) tended to be higher for algorithm 1 than for algorithm 2. The validity (accuracy, ranging from 0.91 to 0.95) and reliability (Kappa index, ranging from 0.68 to 0.78) of defining T2DM by NHIS criteria were independent of age, sex, socioeconomic status, and accompanied hypertension or dyslipidemia.Conclusion: The operational definition of T2DM based on population-based NHIS claims data, including diagnostic codes and prescription codes, could be a valid tool to identify individuals with T2DM in the Korean population.<\/jats:p>","DOI":"10.4093\/dmj.2022.0375","type":"journal-article","created":{"date-parts":[[2023,2,8]],"date-time":"2023-02-08T01:18:38Z","timestamp":1675819118000},"page":"201-210","update-policy":"https:\/\/doi.org\/10.4093\/crossmark_policy","source":"Crossref","is-referenced-by-count":43,"title":["Comparison of Operational Definition of Type 2 Diabetes Mellitus Based on Data from Korean National Health Insurance Service and Korea National Health and Nutrition Examination Survey"],"prefix":"10.4093","volume":"47","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1524-1742","authenticated-orcid":true,"given":"Jong Ha","family":"Baek","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong-Moon","family":"Park","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyung Do","family":"Han","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min Kyong","family":"Moon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jong Han","family":"Choi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3703-1479","authenticated-orcid":true,"given":"Seung-Hyun","family":"Ko","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2567","reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1136\/bmjdrc-2020-001355"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1186\/s12933-020-01032-5"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.4093\/dmj.2020.0008"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.4093\/dmj.2022.0193"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.4093\/dmj.2018.42.2.93"},{"key":"ref6","first-page":"3787","volume-title":"The oral glucose tolerance test: 100 years later","author":"Jagannathan","year":"2020"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.4093\/dmj.2016.40.1.79"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.2337\/dc20-1533"},{"key":"ref9","first-page":"e29551","volume-title":"Prevalence and comorbidities of bronchiolitis in adults: a population-based study in South Korea","author":"Jeong","year":"2022"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-021-96483-5"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1136\/bmjopen-2021-048784"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1097\/gme.0000000000001848"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1097\/hjh.0000000000001842"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1016\/j.diabres.2021.108946"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.4093\/dmj.2022.0106"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1097\/md.0000000000025045"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.4093\/dmj.2020.0175"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1136\/bmjopen-2015-009952"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1093\/ije\/dyt228"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1186\/s40885-019-0124-x"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.3904\/kjim.2019.188"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1038\/ki.2013.444"},{"key":"ref23","first-page":"5","volume-title":"What is moderate drinking?: defining \u201cdrinks\u201d and drinking levels","author":"Dufour","year":"1999"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1123\/jpah.5.s1.s30"},{"key":"ref25","first-page":"203","volume-title":"Measures of diagnostic accuracy: basic definitions","author":"Simundic","year":"2009"},{"key":"ref26","doi-asserted-by":"publisher","DOI":"10.2307\/2529310"},{"key":"ref27","doi-asserted-by":"publisher","DOI":"10.1186\/s12913-018-3738-x"},{"key":"ref28","doi-asserted-by":"publisher","DOI":"10.1111\/jdi.13641"},{"key":"ref29","doi-asserted-by":"publisher","DOI":"10.1186\/s12913-018-3148-0"}],"container-title":["Diabetes &amp;
