IntroductionTetanus, diphtheria, and acellular pertussis (Tdap) vaccination has been recommended for adolescents in the U.S. since 2006. Information on Tdap vaccination by provider recommendation is limited. The purpose of this study is to assess recent Tdap vaccination by provider recommendation status among adolescents aged 13-17 years.MethodsThe 2013 National Immunization Survey-Teen data (N=18,948) were analyzed in 2016 to assess national and state-specific Tdap vaccination coverage disparities among adolescents by provider recommendation status, and other demographic and access to care variables. Multivariable logistic regression analysis and predictive marginal modeling evaluated associations between Tdap vaccination and provider recommendation status and other factors among adolescents aged 13-17 years.ResultsOverall, only 56.9% of adolescents aged 13-17 years received a provider recommendation for Tdap. Coverage was significantly higher among adolescents with a provider recommendation (88.6%) compared with those without a provider recommendation (80.5%) (p<0.05). Multivariable logistic regression showed that characteristics independently associated with a higher likelihood of Tdap vaccination included receiving a provider recommendation, Hispanic ethnicity, having two to three physician contacts in the past 12 months, having one or two vaccination providers, and receiving vaccinations from more than one type of facility (p<0.05).ConclusionsProvider recommendations were significantly associated with Tdap vaccination among adolescents aged 13-17 years. However, 43% of parents of adolescents did not receive a provider recommendation. Evidence-based strategies such as standing orders and provider reminders alone or health systems interventions in combination should be taken to improve provider recommendation and Tdap vaccination coverage.Published by Elsevier Inc.
