Concordance of adolescent human papillomavirus vaccination parental report with provider report in the National Immunization Survey-Teen (2008–2013)

Objectives To examine the accuracy of parental report of HPV vaccination through examination of concordance, with healthcare provider vaccination report as the comparison. Methods The 2008–2013 National Immunization Survey (NIS)-Teen was used to examine accuracy of parent reports of HPV vaccination for their female daughters aged 13–17 years, as compared with provider report of initiation and number of doses. Multivariable logistic regression models were used to examine associations related to concordance of parent and provider report. Results Of 51,746 adolescents, 84% concordance for HPV vaccine initiation and 70% concordance for number of doses was observed. Accuracy varied by race/ethnicity, region, time, and income. The parent report of number of doses was more likely to be accurate among parents of 13 and 14 year old females than 17 year olds. Accuracy of initiation and number of doses were lower among Hispanic and black adolescents compared to white parents. The odds of over-report was higher among minorities compared to whites, but the odds of underreport was also markedly higher in these groups compared to parents of white teens. Accuracy of parental vaccine report decreased across time. Conclusions These findings are important for healthcare providers who need to ascertain the vaccination status of young adults. Strengthening existing immunization registries to improve data sharing capabilities and record completeness could improve vaccination rates, while avoiding costs associated with over-vaccination.
