Methods: Patients with suspected intussusception who had ICD-10 code K561 as their discharge diagnosis from the national database were selected, and those who underwent either radiologic and\/or surgical reduction were defined as true intussusception patients. We compared the time periods from patients visiting the ED to ultrasound, radiologic reduction and\/or surgical reduction between the study group (first half of 2020, COVID-19 period) and the control groups (control group 1: first half of 2019, control group 2: second half of 2019). Results: The number of suspected intussusception patients in each group was 1223, 1576, and 624, and the incidence rates were 7.85, 11.30, and 4.19 per 100,000 person-half-years (control group 1, control group 2, study group, respectively, p &lt; 0.05). No differences in terms of the time from the ED visit to ultrasound, radiological reduction and\/or surgical reduction were noted between the study group and the control groups. Conclusions: In Korea, the COVID-19 pandemic did not significantly affect the ED treatment process or the results of patients with intussusception.<\/jats:p>","DOI":"10.3390\/children9020277","type":"journal-article","created":{"date-parts":[[2022,2,17]],"date-time":"2022-02-17T20:24:26Z","timestamp":1645129466000},"page":"277","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Impact of the COVID-19 Pandemic on Emergency Care Utilization and Outcomes in Pediatric Patients with Intussusception"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2385-2834","authenticated-orcid":false,"given":"Jin Hee","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Emergency Medicine, Seoul National University Bundang Hospital, Seongnam 13620, Korea"},{"name":"Department of Emergency Medicine, Seoul National University College of Medicine, Seoul 03080, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3634-9573","authenticated-orcid":false,"given":"Young Sun","family":"Ro","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, Seoul National University Hospital, Seoul 03080, Korea"},{"name":"National Emergency Medical Center, National Medical Center, Seoul 04564, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0960-0198","authenticated-orcid":false,"given":"Hyuksool","family":"Kwon","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, Seoul National University Bundang Hospital, Seongnam 13620, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2449-1006","authenticated-orcid":false,"given":"Dongbum","family":"Suh","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, Seoul National University Bundang Hospital, Seongnam 13620, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9950-3449","authenticated-orcid":false,"given":"Sungwoo","family":"Moon","sequence":"additional","affiliation":[{"name":"National Emergency Medical Center, National Medical Center, Seoul 04564, Korea"},{"name":"Department of Emergency Medicine, Korea University Ansan Hospital, Ansan 15355, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,2,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"41","DOI":"10.1162\/asep_a_00803","article-title":"COVID-19 in Korea: Success Based on Past Failure","volume":"20","author":"Lim","year":"2021","journal-title":"Asian Econ.
