Screening newborns after 24 hours of life with pulse oximetry to detect critical (hypoxemic) congenital heart defects was recommended in 2011. To assess the effect of mandatory screening policies on mortality reduction, researchers analyzed U.S. live birth–infant death data for the period 2007 to 2013. They compared rates of early deaths (between age 24 hours and 6 months) from 12 types of CHD conditions between states with versus without mandatory screening.
Between 2011 and 2013, eight states implemented mandatory screening, five states introduced nonmandatory screening, and nine introduced mandatory screening but had not yet implemented screening by 2013. Nationally, between 2007 and 2013, some 2700 infant deaths occurred from critical CH…
