Sources of information for assessing human papillomavirus vaccination history among young women

Assessing history of human papillomavirus (HPV) vaccination is important for monitoring vaccine uptake, impact, and effectiveness. Based on data collected from 1720 women with high-grade cervical lesions reported to a statewide surveillance system in Connecticut, we found that available medical records did not contain HPV vaccination information for 34% of women, and 43% of women could not be reached for interview. When both were used for data collection, concordance of vaccination history (83%) and sensitivity of self-report (96%) were both high. Reviewing medical records based on self-reported information about vaccine providers increased confirmation of vaccination histories in this sample by 18%. The vaccine registry in Connecticut is not currently utilized for HPV vaccinations, but efforts to increase use for adolescent vaccines could be useful in the future to overcome limitations of other sources.
