Late-preterm infants have greater morbidity and total health care costs than term infants, and these differences persist throughout the first year of life. Management strategies and guidelines to reduce morbidity and costs in late-preterm infants should be investigated.

Children at high risk for RSV (CLD, CHD and prematurity), those with severe underlying comorbidities, or those with nosocomial RSV appear to be at increased risk for death after RSV hospitalization. More data are needed on cause of death and how much is directly attributable to RSV.

BACKGROUND: Respiratory syncytial virus (RSV) is a leading cause of lower respiratory tract infection (LRTI) in infants and young children, accounting for approximately 75,000-125,000 hospitalizations per year. It is estimated that in 2000, RSV infection accounted for 1.7 million office visits, 402,000 emergency room visits, and 236,000 hospital outpatient visits per year for children younger than 5 years of age. Palivizumab, a humanized monoclonal antibody directed against RSV, is the only immunoprophylaxis therapy approved by the FDA for prevention of serious lower respiratory tract disease caused by RSV in infants (up to 2 years of age) who meet 1 or more of the following criteria for high risk: (a) gestational age up to 35 weeks; (b) diagnosis of chronic lung disease (CLD, formerly bronchopulmonary dysplasia [BPD]); or (c) diagnosis of cyanotic or complex congenital heart disease. The RSV season typically occurs between November and March but may vary by region. During the period of our review, depending on local duration of the RSV season, infants usually required 5 monthly (every 28-30 days) intramuscular injections of palivizumab. Infants born in the middle of the season received their palivizumab doses from the time of birth to the end of the season and, therefore, may have required less than 5 doses. It is unclear if compliance with monthly doses is a problem and whether noncompliance increases the risk of RSV hospitalizations in routine clinical practice.
