Data from the NIS database do not enable identification of which patients had received immunoprophylaxis. Selective use of immunoprophylaxis during many of the years studied may have reduced the overall incidence of RSV hospitalizations among the CHD population. It is likely that not all high risk children 12-23 months of age with CHD received immunoprophylaxis. No patient-level data were available on the status of surgical correction for the hospitalized children.
