Severity and Cost of RSV Hospitalization Among US Preterm Infants Following the 2014 American Academy of Pediatrics Policy Change.

The American Academy of Pediatrics (AAP) Committee on Infectious Diseases (COID) periodically publishes recommendations for respiratory syncytial virus (RSV) immunoprophylaxis (IP) use in pediatric patients considered to be at highest risk for severe RSV infection. In 2014, for the first time, the AAP COID stopped recommending the use of RSV IP for otherwise healthy infants born at 29 weeks' gestational age (wGA) or later, stating that RSV hospitalization (RSVH) rates in this population are similar to those of term infants. Subsequently, epidemiological studies in the US at national and regional levels provided evidence of the impact of the policy change in 29-34 wGA infants.
