Influenza-Related Knowledge, Beliefs, and Experiences Among Caregivers of Hospitalized Children.

OBJECTIVE Caregivers frequently decline influenza vaccine for their hospitalized child. In this study, we aimed to examine factors impacting their influenza vaccine decision-making. METHODS We conducted a cross-sectional survey study of English- and Spanish-speaking caregivers of children hospitalized at a tertiary care pediatric hospital between November 2017 and April 2018. The survey assessed influenza-related knowledge, beliefs, experiences, and vaccine hesitancy. Multivariable logistic regression examined associations between survey responses and child influenza vaccination status at admission (already vaccinated versus not yet vaccinated this season) and, among caregivers with vaccine-eligible children, influenza vaccine acceptance (versus declination) for their child during hospitalization. RESULTS Caregivers (N =522; 88.9% response rate) were mostly non-Hispanic white (66.9%) and English-speaking (97.7%). At admission, 63.2% of children were already vaccinated this season. The caregiver view that influenza vaccination is important for their child’s health was the strongest positive predictor of having an already vaccinated child (adjusted odds ratio [aOR]: 3.16; 95% confidence interval [CI]: 2.46–4.05); vaccine hesitancy was the strongest negative predictor (aOR: 0.61; 95% CI: 0.50–0.75). Among caregivers with vaccine-eligible children, 30.3% accepted influenza vaccine for their hospitalized child. Their belief regarding the child health benefits of influenza vaccination was associated with vaccine acceptance during hospitalization (aOR: 6.87; 95% CI: 3.38–13.96). Caregiver vaccine hesitancy and agreement that children with mild illness should delay vaccination negatively impacted vaccine acceptance (aOR: 0.39; 95% CI: 0.25–0.62; aOR: 0.33; 95% CI: 0.20–0.56, respectively). CONCLUSIONS We identified key factors impacting influenza vaccine decision-making among caregivers of hospitalized children, a critical step to improving uptake in this population.
