Although hypothermia prevention has been extensively studied in infants &amp;lt;32 weeks\u2019 gestation, the authors of few studies have targeted moderate- and late-preterm infants (MLPIs) in the delivery room.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>METHODS<\/jats:title>\n                  <jats:p>This quality improvement initiative was conducted from June 2019 to June 2023 at the Massachusetts General Hospital NICU and Labor and Delivery Unit. All inborn MLPIs 32\u2009+\u20090\/7 to 36\u2009+\u20096\/7 weeks\u2019 gestation admitted to the NICU were included. We expanded thermoregulatory measures typically used in protocols for infants &amp;lt;32 weeks\u2019 gestation, including increasing delivery room ambient temperature to 74\u00b0F and thermal mattress use. The primary outcome was hypothermia (&amp;lt;36.5\u00b0C) after NICU admission. The balancing measure was hyperthermia (\u226538\u2009\u00b0C).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>During the study period, there were 566 inborn MLPIs with a mean gestational age of 34\u2009+\u20093\/7 weeks and a mean birth weight of 2269 g. Special cause variation in neonatal hypothermia incidence was observed with a decrease from a mean baseline of 27% to 7.8% postintervention. Special cause variation was observed in hyperthermia incidence, with an increase from 1.4% to 6.2% postintervention largely initially associated with noncompliance with the protocol for thermal mattress removal.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>The expansion of several thermoregulation techniques commonly used in infants &amp;lt;32 weeks\u2019 gestation, particularly thermal mattress use, was associated with a decreased incidence of NICU admission hypothermia in MLPIs, with an increase in mild hyperthermia predominantly associated with concomitant polyethylene wrap use.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1542\/peds.2023-065117","type":"journal-article","created":{"date-parts":[[2024,8,22]],"date-time":"2024-08-22T08:10:46Z","timestamp":1724314246000},"source":"Crossref","is-referenced-by-count":9,"title":["Prevention of NICU Admission Hypothermia in Moderate- and Late-Preterm Infants"],"prefix":"10.1542","volume":"154","author":[{"given":"Amanda E.","family":"Winkler","sequence":"first","affiliation":[{"name":"aHarvard Neonatal-Perinatal Medicine Fellowship Program, Boston, Massachusetts"},{"name":"bDivision of Newborn Medicine, Department of Pediatrics"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph H.","family":"Chou","sequence":"additional","affiliation":[{"name":"bDivision of Newborn Medicine, Department of Pediatrics"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elizabeth","family":"West","sequence":"additional","affiliation":[{"name":"cDepartment of Obstetrics, Massachusetts General Hospital, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carolyn","family":"Bleiler","sequence":"additional","affiliation":[{"name":"bDivision of Newborn Medicine, Department of Pediatrics"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janet","family":"Bell","sequence":"additional","affiliation":[{"name":"bDivision of Newborn Medicine, Department of Pediatrics"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeanne","family":"Gilbert","sequence":"additional","affiliation":[{"name":"bDivision of Newborn Medicine, Department of Pediatrics"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christina M.","family":"Duzyj","sequence":"additional","affiliation":[{"name":"cDepartment of Obstetrics, Massachusetts General Hospital, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sergei","family":"Roumiantsev","sequence":"additional","affiliation":[{"name":"bDivision of Newborn Medicine, Department of Pediatrics"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul H.","family":"Lerou","sequence":"additional","affiliation":[{"name":"bDivision of Newborn Medicine, Department of Pediatrics"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Megan","family":"Aurora","sequence":"additional","affiliation":[{"name":"bDivision of Newborn Medicine, Department of Pediatrics"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"417","published-online":{"date-parts":[[2024,8,22]]},"reference":[{"issue":"2","key":"2024090102520664600_B1","doi-asserted-by":"crossref","first-page":"271","DOI":"10.1016\/j.jpeds.2013.09.049","article-title":"Hypothermia and early neonatal mortality in preterm infants","volume":"164","author":"de Almeida","year":"2014","journal-title":"J Pediatr"},{"issue":"3","key":"2024090102520664600_B2","doi-asserted-by":"crossref","first-page":"e643","DOI":"10.1542\/peds.2006-0943","article-title":"Admission temperature of low birth weight infants: predictors and associated morbidities","volume":"119","author":"Laptook","year":"2007","journal-title":"Pediatrics"},{"key":"2024090102520664600_B3","doi-asserted-by":"crossref","first-page":"S49","DOI":"10.1038\/jp.2010.177","article-title":"Hypothermia in very low birth weight infants: distribution, risk factors and outcomes","volume":"31","author":"Miller","year":"2011","journal-title":"J Perinatol"},{"key":"2024090102520664600_B4","first-page":"1","volume-title":"Thermal Protection of the Newborn: A Practical Guide","author":"World Health Organization","year":"1997"},{"key":"2024090102520664600_B5","doi-asserted-by":"crossref","first-page":"S120","DOI":"10.1542\/peds.2015-3373D","article-title":"Part 7: neonatal resuscitation: 2015 international consensus on cardiopulmonary resuscitation and emergency cardiovascular care science with treatment recommendations","volume":"136","author":"Perlman","year":"2015","journal-title":"Pediatrics"},{"issue":"9","key":"2024090102520664600_B6","first-page":"1367","article-title":"Hypothermia in Iranian newborns.
