Background In 2014, the American Academy of Pediatrics stopped recommending RSV immunoprophylaxis (RSV IP) for otherwise healthy infants 29–34 weeks gestational age (wGA), while continuing to recommend RSV IP for infants born at <29 wGA. The decline in RSV IP and associated increase in RSV hospitalizations (RSVH) among infants 29–34 wGA have been described previously, but potential effects of the 2014 guidance change on preterm infants <29 wGA are unknown. This study compared 2012–2014 and 2014–2016 outpatient RSV IP use as well as RSVH rates relative to term infants among otherwise healthy <29 wGA infants. Methods Infants born from July 1, 2011 to June 30, 2016 were followed from birth hospitalization discharge through their rst year of life in the MarketScan Commercial (COM) and Multistate Medicaid (MED) databases. DRG and ICD codes identified term and <29 wGA infants at birth. RSV IP receipt was derived from pharmacy and outpatient medical claims (inpatient RSV IP data were unavailable). RSVH were derived from inpatient medical claims. RSVH IP use and RSVH were assessed across three chronologic age (CA) groups: <3 months, 3–<6 months, and 6–<12 months. RSVH rate ratios for 2012–2014 and 2014–2016 were calculated for <29 wGA infants using healthy term infants 0–<12 months of age as a reference category. Results Outpatient RSV IP receipt fell after 2014 for <29 wGA infants across all CA categories, with the greatest decline observed among infants <3 months CA (Table 1). Greater RSVH rates for <29 wGA infants relative to term infants were observed after 2014 (Figures 1 and 2), with infants <3 months CA experiencing the greatest percentage increases in relative RSVH risks. Conclusion Outpatient RSV IP decreased and RSVH relative to term infants increased among otherwise healthy <29 wGA infants following the 2014 policy change, even though RSV IP continued to be recommended. The effects were greatest for infants <3 months CA and those insured by Medicaid. Funded by AstraZenecaTable 1.
