Abstract
Introduction:
Several studies have examined predictors of HPV vaccine initiation and completion. Two common methods to measure HPV vaccine initiation and completion are parental recall and provider verified vaccine history. Some studies use parental recall because it is cost-effective and time-consuming. Others argue that the provider report should be used because it is the gold standard, although it is more costly and time-consuming. Yet, few studies compare the accuracy of parental report versus provider report for HPV vaccine initiation and completion.
Objective:
To compare the accuracy of parental reported and provider reported data on HPV vaccine initiation and completion among a national sample of adolescents in the United States.
Methods:
Data from the 2014 National Immunization Survey-Teen (NIS-Teen) were analyzed for 38,703 adolescents. HPV vaccine initiation and completion were assessed using parental recall (shot cards) and provider verified (medical records) vaccine history. Adjusted, weighted multivariable logistic regression compared the accuracy of parental and provider reported data on HPV vaccine initiation and completion.
Results:
HPV vaccine initiation (a) and completion (b), by subgroup analysis, is similar for parental recall and provider report. However, subgroup analyses for parental report were slightly lower than provider report, although not statistically significant (Table 1).
Conclusion:
This study showed that parental report is comparable to provider report when measuring HPV vaccine initiation and completion among adolescents in the US. For more cost-effective and timely assessment of vaccine uptake, an accurate and practical method of measuring HPV vaccine initiation and completion is paramount. Utilizing parental report may be a more cost-effective and timely alternative to provider report for clinical evaluation of vaccine uptake.
