Association between provider recommendation and influenza vaccination status among children.

BACKGROUND: Provider recommendation is associated with influenza vaccination receipt. The objectives of this study were to estimate the percentage of children 6 months-17 years for whom a provider recommendation for influenza vaccination was received, identify factors associated with receipt of provider recommendation, and evaluate the association between provider recommendation and influenza vaccination status among children.

METHODS: National Immunization Survey-Flu (NIS-Flu) parentally reported data for the 2013-14, 2014-15, and 2015-16 seasons were analyzed. Tests of association between provider recommendation and demographic characteristics were conducted using Wald chi-square tests and pairwise comparison t-tests. Multivariable logistic regression was used to determine variables independently associated with receiving provider recommendation and the association between provider recommendation and influenza vaccination status.

RESULTS: Approximately 70% of children had a parent report receiving a provider recommendation for influenza vaccination for their child. The strongest association between receipt of provider recommendation and demographic characteristics was with child's age, with younger children (6-23 months, 2-4 years, and 5-12 years) being more likely to have a provider recommendation than older children (13-17 years). In addition, children living in a household above poverty with household income >$75,000 were more likely to have a parent report receipt of a provider recommendation than children living below poverty. Children with a provider recommendation were twice as likely to be vaccinated than those without.

CONCLUSIONS: This study affirms the importance of provider recommendation for influenza vaccination among children. Ensuring that parents of all children receive a provider recommendation may improve vaccination coverage.
