The objective of this study was to evaluate the incidence and predictors of CSTS failure, focusing on late-preterm infants.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>METHODS:<\/jats:title>\n                  <jats:p>We performed a retrospective review of late-preterm infants born from 2013 to 2017 to identify the incidence and predictors of CSTS failure, focusing on location of admission. We performed multivariable linear regression to assess the effect of CSTS results on length of stay (LOS).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS:<\/jats:title>\n                  <jats:p>We identified 918 subjects who underwent CSTSs, of whom 4.6% failed. Those infants who were admitted to both the NICU and nursery before discharge had the highest failure rate (8.5%). Of those who failed, 24% failed \u22652 CSTSs. Of these, 20% (all from the nursery) were found to have obstructive apnea and desaturations, and a total of 40% required supplemental oxygen for safe discharge from the hospital. Although crude LOS was longer for those who failed an initial CSTS, when accounting for location of admission, level of prematurity, and respiratory support requirements, the CSTS result was not a significant predictor of longer LOS.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS:<\/jats:title>\n                  <jats:p>A concerning number of late-preterm infants demonstrated unstable respiratory status when placed in their car seat. Those who failed repeat CSTSs frequently had underlying respiratory morbidities that required escalation of care. Although further study is warranted, LOS was not associated with CSTS results but rather with the cardiorespiratory immaturity noted or discovered by performing a CSTS.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1542\/peds.2019-1703","type":"journal-article","created":{"date-parts":[[2019,12,20]],"date-time":"2019-12-20T13:25:45Z","timestamp":1576848345000},"source":"Crossref","is-referenced-by-count":16,"title":["Car Seat Tolerance Screening for Late-Preterm Infants"],"prefix":"10.1542","volume":"145","author":[{"given":"Aimee","family":"Magnarelli","sequence":"first","affiliation":[{"name":"National Institutes of Health, Bethesda, Maryland; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nina","family":"Shah Solanki","sequence":"additional","affiliation":[{"name":"Division of Neonatology, Department of Pediatrics, School of Medicine, University of Maryland, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natalie L.","family":"Davis","sequence":"additional","affiliation":[{"name":"Division of Neonatology, Department of Pediatrics, School of Medicine, University of Maryland, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"417","published-online":{"date-parts":[[2020,1,1]]},"reference":[{"key":"2021121016072189500_B1","doi-asserted-by":"crossref","unstructured":"Centers for Disease Control and Prevention.
