The objectives were 1) to determine the usage of iNO among preterm neonates &lt;35 weeks before and after the 2010 National Institutes of Health consensus statement and 2) to evaluate characteristics and outcomes among preterm neonates who received iNO.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This is a population\u2010based cross\u2010sectional study. Billing and procedure codes were used to determine iNO usage. Data were queried from the National Inpatient Sample from 2004 to 2016. Neonates were included if gestational age was &lt;35 weeks. The epochs were spilt into 2004\u20132010 (Epoch 1) and 2011\u20132016 (Epoch 2). Prevalence of iNO use, mortality, bronchopulmonary dysplasia (BPD), intraventricular hemorrhage, length of stay, mechanical ventilation, and cost of hospitalization.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There were 4865 preterm neonates &lt;35 weeks who received iNO. There was a significant increase in iNO use during Epoch 2 (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). There was significantly higher use in Epoch 2 among neonates small for gestational age (SGA)\u00a02.3% versus 7.2%, congenital heart disease (CHD) 11.1% versus 18.6%, and BPD 35.2% versus 46.8%.

The increased use of iNO among preterm neonates may be targeted at specific high\u2010risk populations such as SGA and CHD\u00a0neonates. There was lower mortality in Epoch 2; however, the cost was doubled.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ppul.25775","type":"journal-article","created":{"date-parts":[[2021,11,29]],"date-time":"2021-11-29T12:26:47Z","timestamp":1638188807000},"page":"427-434","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Epidemiologic
