Vaccine Administration in Children’s Hospitals

Abstract

OBJECTIVES: To examine inpatient vaccine delivery across a national sample of children’s hospitals. METHODS: We conducted a retrospective cohort study examining vaccine administration at 49 children’s hospitals in the Pediatric Health Information System database. Children <18 years old admitted between July 1, 2017, and June 30, 2019, and age eligible for vaccinations were included. We determined the proportion of hospitalizations with ≥1 dose of any vaccine type administered overall and by hospital, the type of vaccines administered, and the demographic characteristics of children who received vaccines. We calculated adjusted hospital-level rates for each vaccine type by hospital. We used logistic and linear regression models to examine characteristics associated with vaccine administration. RESULTS: There were 1 185 667 children and 1 536 340 hospitalizations included. The mean age was 5.5 years; 18% were non-Hispanic Black, and 55% had public insurance. There were ≥1 vaccine doses administered in 12.9% (95% confidence interval: 12.8–12.9) of hospitalizations, ranging from 1% to 45% across hospitals. The most common vaccines administered were hepatitis B and influenza. Vaccine doses other than the hepatitis B birth dose and influenza were administered in 1.9% of hospitalizations. Children had higher odds of receiving a vaccine dose other than the hepatitis B birth dose or influenza if they were <2 months old, had public insurance, were non-Hispanic Black race, were medically complex, or had a length of stay ≥3 days. CONCLUSIONS: In this national study, few hospitalizations involved vaccine administration with substantial variability across US children's hospitals. Efforts to standardize inpatient vaccine administration may represent an opportunity to increase childhood vaccine coverage.

Policy of vaccination of “fragile children”: Results of a survey of 14 Italian children’s hospitals

“…Compliance with vaccination has been repeatedly challenged during the last decades. 7 , 8 Thus, physicians – and in particular pediatricians – should feel the moral mandate to continuously support and develop the confidence of the parents and families toward active immunization. It is a common experience that vaccination coverage among pediatric inpatients is lower than in the general population, and hospitalization has been shown to be a risk factor for delaying or missing immunization in children.…”
