Emergency departments: An underutilized resource to address pediatric influenza vaccine coverage.

BACKGROUND: Emergency department (ED) based influenza vaccine (IV) programs have been successful in adults; however, little is known about pediatric ED IV programs in terms of prevalence, feasibility, or successful implementation. AIMS: To describe the reach and effectiveness of IV practices in pediatric EDs, and identify IV facilitators and barriers. METHODS: We assessed, via cross-sectional survey of pediatric ED physicians, number of EDs offering IV to children, vaccines administered annually, and perceived facilitators/barriers to vaccination. The proportion of EDs offering IV is reported. Chi-square tests compared facilitators and barriers among high performers (≥50 IV/year), low performers (<50 IV/yr), and non-vaccinators. We calculated an area of missed effect for the number of children who could be vaccinated if non-vaccinating EDs offered IV. RESULTS: Among 492 physicians from 166 EDs, 142 responded (representing 61 (37.3 %) EDs). Most EDs were in large, urban, academic, freestanding children's hospitals (Table 1). Only twenty-six EDs (44.3 %) offer ≥ 1 IV/yr. Seventeen (65.4 %) were low performers, five (19.2 %) high performers, and four (15.4 %) were model programs. High/model performers used establish workflows more commonly than lower performers (78 % vs. 33 %), although this was not statistically significant (p = 0.077). Common facilitators included: strong provider and administration buy-in, electronic health record facilitation, storage/accessibility, and having a leadership team/champion (Fig. 1). Non-vaccinators commonly perceived lack of these factors as barriers. Many (24/61, 39.3 %) EDs expressed interested in establishing or growing IV programs. Up to 18,250 unvaccinated children could receive IV annually if non-vaccinating EDs offered IV during influenza season. CONCLUSIONS: Over half of EDs participating in the Pediatric Emergency Medicine Collaborative Research Committee do not currently offer pediatric IV. Addressing identified barriers/facilitators to develop IV programs in EDs has potential to improve vaccination rates, especially among minority and underserved children.
