All clinical data in the electronic health record were extracted and deposited into an integrated data repository that was used for this work.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>We identified 225 new sepsis episodes in 216 patients. An evaluation for sepsis-associated coagulopathy was performed in 96 (43%) episodes. Gram-negative pathogen, nSOFA score at evaluation, and mortality were greater among episodes that included a coagulopathy evaluation compared with those that did not. Abnormal coagulation results were common (271\/339 evaluations; 80%) and were predominantly prothrombin times. Intervention (plasma or cryoprecipitate) followed a minority (84\/271; 31%) of abnormal results, occurred in 40\/96 (42%) episodes that were often associated with &amp;gt;1 intervention (29\/40; 73%), and coincided with thrombocytopenia in 37\/40 (93%) and platelet transfusion in 27\/40 (68%). Shapley Additive Explanations modeling demonstrated strong predictive performance for the composite outcome of death and\/or treatment for coagulopathy in neonates (f1 score 0.8, area under receiver operating characteristic curve 0.83 for those with abnormal coagulation values). The three most important features influencing the composite outcome of death or treatment for coagulopathy included administration of vasoactive medications, hematologic dysfunction assessed by the maximum nSOFA platelet score, and early sepsis (\u226472\u2005h after birth).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>A coagulopathy evaluation was performed in a minority of NICU patients with sepsis and was associated with greater illness severity and mortality. Abnormal results were common but infrequently associated with intervention, and intervention was contemporaneous with thrombocytopenia. The most important feature that influenced the composite outcome of death or treatment for coagulopathy was the administration of vasoactive-inotropic medications. These data help to identify NICU patients at risk of sepsis-associated coagulopathy.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fped.2024.1364725","type":"journal-article","created":{"date-parts":[[2024,3,5]],"date-time":"2024-03-05T00:02:33Z","timestamp":1709596953000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":10,"title":["The frequency and timing of sepsis-associated coagulopathy in the neonatal intensive care unit"],"prefix":"10.3389","volume":"12","author":[{"given":"Khyzer B.","family":"Aziz","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew","family":"Saxonhouse","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Divya","family":"Mahesh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kathryn E.","family":"Wheeler","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James L.","family":"Wynn","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,3,5]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"801","DOI":"10.1001\/jama.2016.0287","article-title":"The third international consensus definitions for sepsis and septic shock (sepsis-3)","volume":"315","author":"Singer","year":"2016","journal-title":"JAMA"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2024.0179","article-title":"International consensus criteria for pediatric sepsis and septic shock","author":"Schlapbach","year":"2024","journal-title":"JAMA"},{"key":"B3","doi-asserted-by":"publisher","first-page":"707","DOI":"10.1007\/BF01709751","article-title":"The SOFA (Sepsis-related Organ Failure Assessment) score to describe organ dysfunction\/failure.
