Using RWE, this study sought to examine the prevalence of treated TD, use of medical utilization, and use of prescription drugs among patients with TD with respect to TD type and comorbid psychiatric illness.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>We performed a retrospective cross-sectional study. Using the Korean Health Insurance Review and Assessment Service Pediatric Patient Sample data from 2009 to 2016, we analyzed 20,599 patients with TD (Korean Standard Classification of Diseases-6\/7 code: F95.x) aged 2\u201319 years.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The annual average TD prevalence was 2.6\/1000 population (95% confidence interval, 2.3\u20132.8\/1000). Between 2009 and 2016, a slight increase in TD prevalence was observed from 1.9 to 2.9\/1000 population. The TD prevalence rate in male patients was four times higher than that in female patients. Differences were observed in health care utilization and drug prescription types between patients with Tourette syndrome and chronic or transient TD. In addition, more than half of patients with TD had comorbid psychiatric disorders, and one-third of patients with TD had attention-deficit\/hyperactivity disorder (ADHD). Patients with TD without comorbidities were frequently prescribed aripiprazole, while patients with TD and comorbid ADHD were frequently prescribed atomoxetine, methylphenidate, risperidone, and aripiprazole.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>This study described the epidemiological characteristics of TD based on recent RWE from Korea, and its findings can help establish future TD evidence-based clinical guidelines and related policies.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1089\/cap.2019.0050","type":"journal-article","created":{"date-parts":[[2019,7,30]],"date-time":"2019-07-30T16:10:14Z","timestamp":1564503014000},"page":"764-772","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":20,"title":["Population-Based Epidemiology of Pediatric Patients with Treated Tic Disorders from Real-World Evidence in Korea"],"prefix":"10.1177","volume":"29","author":[{"given":"Seungjin","family":"Choi","sequence":"first","affiliation":[{"name":"Department of Child and Adolescent Psychiatry, Severance Children's Hospital, Institute of Behavioral Science in Medicine, Yonsei University College of Medicine, Seoul, Republic of Korea."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hankil","family":"Lee","sequence":"additional","affiliation":[{"name":"College of Pharmacy, Yonsei Institute of Pharmaceutical Sciences, Yonsei University, Incheon, Republic of Korea."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dong-Ho","family":"Song","sequence":"additional","affiliation":[{"name":"Department of Child and Adolescent Psychiatry, Severance Children's Hospital, Institute of Behavioral Science in Medicine, Yonsei University College of Medicine, Seoul, Republic of Korea."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keun-Ah","family":"Cheon","sequence":"additional","affiliation":[{"name":"Department of Child and Adolescent Psychiatry, Severance Children's Hospital, Institute of Behavioral Science in Medicine, Yonsei University College of Medicine, Seoul, Republic of Korea."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2019,12,2]]},"reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"crossref","unstructured":"American Psychiatric Association: Diagnostic and Statistical Manual of Mental Disorders 5th ed.
