Episodic Cost of Lower Respiratory Tract Illness Due to Respiratory Syncytial Virus Among US Infants During the First Year of Life

A study using two healthcare claims databases (commercial, Medicaid) was undertaken to estimate episodic cost of lower respiratory tract illness due to respiratory syncytial virus (RSV-LRTI) among infants aged <12 months overall, by age, and by birth gestational age (weeks [wGA]). Among commercial-insured infants, mean costs were $28,812 for hospitalized episodes, $2,575 for emergency department episodes, and $336 for outpatient clinic episodes; costs were highest among infants aged <1 month and infants with wGA ≤32, and were comparable-albeit somewhat lower-among Medicaid-insured infants. Cost of RSV-LRTI during acute phase of illness is high, especially among youngest and premature infants.
