Maternal influenza vaccination: evaluation of a patient-centered pamphlet designed to increase uptake in pregnancy.
We developed and tested a theoretically-based pamphlet entitled 'Influenza in Pregnancy,' specifically designed to increase pregnant women's knowledge, reduce barriers to maternal vaccination, and subsequently improve vaccine uptake. A randomized control trial was conducted on pregnant women (n = 135) at three locations in Connecticut during the 2011-2012 season to evaluate the impact of the patient-centered pamphlet. The women were randomized to one of three groups: the pamphlet; pamphlet/benefit statement (vaccinating the pregnant woman also benefits the young infant); or control. A Chi square analysis compared the intervention with control using the primary outcome of vaccination. A secondary outcome of the perceptions of health beliefs of maternal vaccination were measured through General Linear Model/ANOVA model for repeated measures. Overall 66.9% (89/133) were vaccinated. Both the pamphlet group 72.9% (35/48) (χ² = 6.81, df = 1 p = .009), and the pamphlet/benefit statement group 86.1% (31/36) (χ² = 13.74, df = 1, p < .001), had significantly higher vaccine uptake than the control group 46.9% (23/49). The potential barrier, perception of vaccine safety (F = 4.973, df = 2, p < .01), and benefit of vaccination to mother and infant (F = 6.690, df = 2, p < .01) significantly improved for the intervention groups compared to control group. The pamphlet significantly increased the pregnant women's perceptions of the safety and benefit of the vaccine, and the overall uptake.
