ABSTRACT To describe influenza vaccination rates and identify risk factors for missing vaccination among children with asthma in managed Medicaid.
As part of a longitudinal study of asthma care quality, parents of children aged 2-16 years with asthma enrolled in Medicaid managed care organizations in Massachusetts, Washington, and California were surveyed by telephone at baseline and 1 year. We evaluated influenza vaccination rates during the follow-up year.
The study population included 1058 children with asthma. The influenza vaccination rate was 16% among all children with asthma and 21% among those with persistent asthma. Children with persistent asthma (odds ratio [OR] 0.53, 95% confidence interval [CI] 0.36-0.79) and those who had been hospitalized during the follow-up year (OR 0.29, 95% CI 0.11-0.76) were less likely to miss vaccination. Children older than 9 years (OR 1.66, 95% CI 1.13-2.46) and children of parents with less than a high school education (OR 2.29, 95% CI 1.05-5.03), compared with a college degree, were at risk for missing vaccination. Among children with persistent asthma, older children (OR 1.65, 95% CI 1.01-2.69) and children of parents with less than a high school education (OR 4.13, 95% CI 1.43-11.90) were more likely to miss influenza vaccination.
Our findings suggest that interventions directed toward older children and families with lower educational levels may help improve influenza vaccination rates among this high-risk group. The low overall vaccination rate highlights the need for improvement in this important component of asthma care quality for all children with asthma.

    ABSTRACT: Data from the Behavioral Risk Factor Surveillance System was used to determine if parents' decisions to vaccinate children against seasonal influenza conform to predictions made by theories of preventive health behavior that postulate increased preventive action with increased risk. Results indicated that parents of children with active asthma were more likely to report influenza vaccination than parents of children who never had asthma (OR = 3.5, 95% CI 2.4–5.1). There was no difference in vaccination frequency reported by parents of children without asthma and children whose asthma is in remission (OR = .8, 95% CI.4–1.4). Parents of children whose asthma is in remission will require additional education and prompting to encourage needed influenza vaccination.

    ABSTRACT: The morbidity and mortality associated with influenza is substantial in children with asthma. There are no available data on the safety and immunogenicity of influenza vaccine in children with asthma in Latin America. Furthermore, it is unclear if influenza vaccination may cause asthma exacerbations. We conducted a placebo-controlled trial to investigate the safety and immunogenicity of an inactivated trivalent split virus influenza vaccine in children with asthma in Mexico. We also measured the impact of influenza vaccination on pulmonary function tests in this population. The inactivated influenza vaccine was immunogenic and safe in terms of local and systemic side effects compared to placebo. We observed no significant impact on pulmonary function tests among vaccine recipients. Given the significant morbidity associated with influenza in children, strategies to promote increased influenza vaccination coverage in this high-risk group in Latin America and elsewhere are urgently needed.

    ABSTRACT: National guidelines have historically varied for influenza vaccination of children with asthma, depending on asthma severity. This study aims to explore perspectives of primary care physicians regarding influenza vaccination practices for children with persistent versus intermittent asthma. A cross-sectional survey was mailed to general pediatricians (n = 300) and family physicians (n = 300) in primary care offices in Michigan in 2006. The main outcome measures included physicians' influenza vaccination recommendations and reasons for nonadministration of influenza vaccine to children with asthma for the 2005-2006 influenza season. Ninety-six percent of respondents (N = 320) reported routinely recommending influenza vaccination for children with persistent asthma; fewer (82%) reported routinely recommending influenza vaccination for those with intermittent asthma. The adjusted odds of recommending influenza vaccination for intermittent asthma patients was significantly higher among pediatricians versus family physicians (adjusted odds ratio 3.49, 95% confidence interval, 1.68-7.22), controlling for other practice characteristics. Regardless of specialty, physicians with more than 25 asthma patients were more likely than those with fewer asthma patients to routinely recommend influenza vaccination. Physicians who do not routinely recommend influenza vaccination to children with intermittent asthma were more likely to cite overlooking discussion of influenza vaccine during the visit (50% vs 13%, respectively; P < .0001) as a reason for lack of vaccination. Influenza vaccination practices of primary care physicians reflect the inconsistencies historically found in national recommendations. Further research is warranted to determine whether the recent clarification of recommendations of the National Asthma Education and Prevention Program (NAEPP) to remove distinctions by asthma severity is associated with a reduction in missed opportunities to vaccinate.
