This retrospective, single\u2010center, cross\u2010sectional study included 33,158 admissions for patients \u2264\u200917\u2009years old admitted to the Children's Hospital (CH) between January 1, 2017, and December 31, 2021. Data was abstracted using Vizient Clinical Data Base and the internal data warehouse. A Poisson regression model was implemented to compare admission diagnosis patterns during the pre\u2010 and intra\u2010pandemic phases. CH SARS\u2010CoV\u20102 prevalence rate was 0.1% in 2020 and 0.5% in 2021. There was a decrease in overall admissions to the CH (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.01) and PICU (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.01) at the onset of the pandemic. There were significant and variable differences in admission patterns for certain infectious and seizure\u2010related diagnoses. The CH experienced an increase in certain specific mental health diagnoses. Seasonality was noted for viral bronchiolitis during the pre\u2010pandemic phase, but was disrupted during the intra\u2010pandemic phase. The COVID\u201019 pandemic had a significant impact on the number and pattern of admissions, despite low prevalence of SARS\u2010CoV\u20102 in our hospital. These changes may be secondary to COVID\u201019 community mitigation strategies. Results can inform anticipated patterns during future pandemics.\n                  <\/jats:p>","DOI":"10.1111\/apm.70165","type":"journal-article","created":{"date-parts":[[2026,3,8]],"date-time":"2026-03-08T09:28:55Z","timestamp":1772962135000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Pediatric Admissions During the\n                    <scp>COVID<\/scp>\n                    \u201019 Pandemic in a Hospital With Low Prevalence of\n                    <scp>SARS<\/scp>\n                    \u2010\n                    <scp>CoV<\/scp>\n                    \u20102"],"prefix":"10.1111","volume":"134","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-1753-8058","authenticated-orcid":false,"given":"Jordon C.","family":"Mitzelfelt","sequence":"first","affiliation":[{"name":"Department of Pediatrics Mayo Clinic Children's  Rochester MN USA"},{"name":"Division of Pediatric Critical Care Medicine Children's Mercy  Kansas City MO USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kristin C.","family":"Mara","sequence":"additional","affiliation":[{"name":"Department of Quantitative Health Sciences Mayo Clinic Children's  Rochester MN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jaclyn","family":"Whelan","sequence":"additional","affiliation":[{"name":"Data Applications and Insights, Vizient  Irving TX USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patrick","family":"Wieneke","sequence":"additional","affiliation":[{"name":"Data Applications and Insights, Vizient  Irving TX USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David J.","family":"Hall","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Mayo Clinic Children's  Rochester MN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthew C.","family":"Authement","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Mayo Clinic Children's  Rochester MN USA"},{"name":"Pediatric Hospital Medicine, Department of Pediatrics Children's Hospital and Medical Center  Omaha NE USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erin E.","family":"Knoebel","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Mayo Clinic Children's  Rochester MN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Travis R.","family":"Kirkpatrick","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Mayo Clinic Children's  Rochester MN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael E.","family":"Nemergut","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology and Perioperative Medicine Mayo Clinic Children's  Rochester MN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Kawai","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Mayo Clinic Children's  Rochester MN USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,2,27]]},"reference":[{"key":"e_1_2_9_2_1","unstructured":"Organization WH \u201cWHO Director\u2010General's Opening Remarks at the Media Briefing on COVID\u201019 \u201daccessed March 5 2021 https:\/\/www.who.int\/director\u2010general\/speeches\/detail\/who\u2010director\u2010general\u2010s\u2010opening\u2010remarks\u2010at\u2010the\u2010media\u2010briefing\u2010on\u2010covid\u201019\u2010\u2010\u201011\u2010march\u20102020."},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2020\u2010039628"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajem.2020.11.037"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.3389\/fped.2022.874045"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chest.2021.03.004"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmjpo\u20102020\u2010000876"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1001\/jamanetworkopen.2020.37227"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1093\/cid\/ciaa710"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1542\/hpeds.2021\u2010006334"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/ppul.25461"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1001\/jamanetworkopen.2023.39884"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00431\u2010021\u201004015\u20100"},{"key":"e_1_2_9_14_1","unstructured":"U.S. Food & Drug Administration \u201cCoronavirus Disease 2019 (COVID\u201019) \u201daccessed March 5 2021 https:\/\/www.fda.gov\/emergency\u2010preparedness\u2010and\u2010response\/counterterrorism\u2010and\u2010emerging\u2010threats\/coronavirus\u2010disease\u20102019\u2010covid\u201019."},{"key":"e_1_2_9_15_1","unstructured":"\u201cOffice of Governor Tim Walz & Lt.
